This application is a continuation of U.S. patent application Ser. No. 17/018,293, filed Sep. 11, 2020, which is a continuation of U.S. patent application Ser. No. 16/123,018, filed Sep. 6, 2018 (now U.S. Pat. No. 10,803,025). All sections of the aforementioned application(s) and patent(s) are incorporated herein by reference in their entirety.
FIELD OF THE DISCLOSUREThe subject disclosure relates to a system and process for scalable and secure content delivery.
BACKGROUNDSome wireless communication networks utilize licensed portions of a frequency spectrum, while others utilize unlicensed portions or combinations of licensed and unlicensed frequency spectra. Examples include mobile cellular service, which often uses licensed frequency spectrum to provide wireless service over a relatively large area, e.g., a macro cell or smaller areas through e.g. a small cell or femto cell serving 4G or 5G wireless service. In at least some instances, mobile cellular service can include wireless service in unlicensed frequency spectra, e.g., through wireless access points. Wireless access points can operate according to wireless protocols, such as IEEE 802.11, including WiFi, Bluetooth and the like. Wireless service is typically available within a geographic region limited in extent with respect to a wireless base station and/or access point providing the service.
Wireless service may be provided to stationary equipment, e.g., a connected home or business, and/or mobile equipment. Wireless services can include, without limitation, voice and/or data services to equipment of mobile users, e.g., smart phones, tablet devices, laptop computers, and the like. Data services can include short message service (SMS), multimedia messaging service (MMS), email, web browsing, file transfer, and the like. Recent trends have also seen a growth in machine-to-machine (M2M) communications, e.g., with the advent of the Internet of Things (IoT), resulting in a rapid expansion in the number of wireless service subscribers. At the same time, applications that use wireless services, such as streaming media, can pose significant bandwidth demands on provider networks.
In order to satisfy increasing demand for connectivity from multiple business verticals, wireless service providers can either expand coverage areas as well as available bandwidth or densify the network through service offerings in various frequency spectra at the same location. For example, a mobile service provider can procure additional licensed spectrum, install and/or upgrade mobile cellular infrastructure including new and/or upgraded macro cell sites, microcell sites and/or femto cell sites, and/or install wireless access points operating in unlicensed spectrum, e.g., WiFi hotspots. While some mobile users can move to favorable locations, e.g., WiFi hotspots when using applications requiring heavy data usage, others may not be able to do so.
Demand for high data rates is increasing to accommodate advances in other technologies, such as connected cars. Autonomous vehicles create a lot of data (in the order of KBs, MBs and even GBs) and exchange part of this data between a vehicle and a (edge) cloud service via a cellular network. Examples of demand for wireless data include firmware updates, passenger entertainment, map updates, positioning correction information, just-in-time services, e.g., to order a parking spot on-demand, and so on. A fourth-generation broadband cellular network technology (4G) is adapted to deliver mobile broadband but was not designed to compensate all new expected new challenges, such as those for connected cars or autonomous vehicles. Although future, e.g., fifth generation broadband cellular network technology (5G) may address some or all of current data demand, its implementation is still far out. Even when deployment begins, it will likely occur incrementally and will likely take years to reach a large coverage of urban spaces.

The subject disclosure describes, among other things, illustrative embodiments that combine mobile cellular licensed and unlicensed spectrum with a peer-to-peer (P2P) file sharing to facilitate transport of massive amounts of data to diverse endpoints. The techniques disclosed herein offload at least some data transport from licensed frequency services to avoid commercial network overload and customer disappointment consuming other services, while also promoting a fast and scalable delivery mechanism for content in the network. Examples disclosed herein include content provided by a producer for wide distribution to machines and/or mobile assets, such as connected cars (CC), drones, smart devices, and the like. For example, transported data content can include, without limitation, layered high definition map updates for CC, no-fly database updates for drones, drone obstacle identification and object/model sharing. More generally, transported data can include high definition multimedia content, e.g., 1080 p, 4 k, 8 k, data sharing, software over-the-air (SOTA), firmware over-the-air (FOTA) updates connected devices, e.g., including CC, drones, smart appliances, map updates, device monitoring and profiling, and the like.

At least some file segments of the set of file segments are transported to equipment of a targeted group of users via an unlicensed frequency spectrum and according to a P2P file sharing process. A secured and signed segmentation record is forwarded to the equipment of the targeted group of users comprising a first group of users and a second group of users, wherein the segmentation record identifies the set of file segments. Progress of a delivery of the set of file segments to the equipment of the targeted group of users is monitored according to the segmentation record. The progress of the delivery of the set of file segments is analyzed to identify a deficiency in delivery of a particular file segment of the set of file segments to the equipment of the targeted group of users. Responsive to the deficiency, the particular file segment is provided to equipment of the first group of users wirelessly via a licensed frequency spectrum.
One or more aspects of the subject disclosure include a process that includes segmenting, by a processing system including a processor, a file to obtain a set of file segments, wherein the file can be regenerated according to a recombination of the set of file segments, and wherein at least some file segments of the set of file segments are transported to equipment of a targeted group of users via an unlicensed frequency spectrum and according to a P2P file sharing process. A segmentation record is provided, by the processing system, to the equipment of the targeted group of users including a first group of users and a second group of users. The segmentation record identifies the set of file segments. A deficiency in delivery of a particular file segment of the set of file segments to the equipment of the targeted group of users is identified, by the processing system, according to the segmentation record.

Although the example illustrates mobile devices 124, 126 in communication with the base station or access point 122, it is understood that the base station or access point 122 can be in communication with other wireless devices that might not necessarily be mobile. Examples of other wireless devices include, without limitation, smart home appliances, e.g., internet accessible thermostats, video surveillance systems, alarm systems, smart meters, and the like.

In various embodiments, the content sources 175 include broadcast television and radio sources, video on demand platforms and streaming video and audio services platforms, one or more content data networks, data servers, web servers and other content servers, and/or other sources of media.
In various embodiments, the communications network 125 can include wired, optical and/or wireless links and the network elements 150, 152, 154, 156, etc. can include service switching points, signal transfer points, service control points, network gateways, media distribution hubs, servers, firewalls, routers, edge devices, switches and other network nodes for routing and controlling communications traffic over wired, optical and wireless links as part of the Internet and other public networks as well as one or more private networks, for managing subscriber access, for billing and network management and for supporting other network functions.
In at least some embodiments, the communication network 100 can facilitate in whole or in part monitoring P2P file sharing, analyzing progress and/or efficiencies of P2P file sharing applications, and/or coordinating activities to increase progress and/or efficiencies. In at least some embodiments, file sharing progress is facilitated by selectively injecting segments into a group of P2P participants. The illustrative example includes a file ingestor 180 and a file distribution facilitator 181. The file ingestor 180 receives a data content item for distribution to a group of targeted wireless devices, e.g., the mobile phones 124 and/or vehicles 126. The file ingestor 180 is in communication with the file distribution facilitator 181. In some embodiments, one or more of the file ingestor 180 or the file distribution facilitator 181 determines whether P2P file sharing should be applied to the received data item. Such decisions can be based on one or more of a number of targeted wireless devices exceeding some threshold, a data size of the data content item exceeding some threshold, a network state, such as available capacity, congestion, error status, and so on.
To the extent that P2P file sharing is employed, the file ingestor 180 disaggregates the data item into a set of smaller data item segments. One of the file ingestor 180, the file distribution facilitator 181 or both generates a segmentation record. In at least some embodiments, the segmentation record provides a complete listing of segments, wherein the original data item can be regenerated, e.g., by a file sharing client application, according to a recombination of the set of data item segments. In some embodiments, one or more of the mobile devices 124 and/or vehicles 126 receives at least some segments of the set of segments from the base station or access point 122 via licensed frequency spectrum. For example, licensed frequency distribution by the base station or access point 122 can be used to provision one or more mobile devices and/or vehicles 126 with some or all of the data item segments. One or more of these receiving mobile devices 124 and/or vehicles 126 is then available to share one or more of the received segments with other mobile devices 124 and/or vehicles according to the P2P process.
In at least some embodiments, a progress of the receiving of data item segments for one or more of the mobile devices and/or vehicles 126 of the group of targeted wireless devices is determined according to the segmentation record. For example, the file distribution facilitator 181 generates a file segmentation record and facilitates distribution of the segmentation record to the targeted wireless devices 124, 126. In some embodiments, the segmentation record can be distributed to each of the targeted wireless devices 124, 126 via the base station or access point 122 using licensed frequency spectrum. According to the illustrative example, each of the targeted wireless devices 124, 126 can maintain a progress report 184a . . . 184e, generally 184. The progress report 184 identifies a progress of receipt of the data item segments of the set of data item segments. In at least some embodiments, the progress report 184 identifies one or more of those data item segments received by the respective targeted wireless device 124, 126, or those data item segments not yet received by the respective targeted wireless device 124, 126, or a combination of segments received and not yet received.
In some embodiments, the targeted wireless devices 124, 136 provide an indication of the progress report 184 to the file distribution facilitator 181. The file distribution facilitator 181, in turn, can analyze the progress reports 184 to determine whether any of the targeted wireless devices 124, 126 require data item segments, which data item segments are required, whether there are any time constraints on a transfer of the complete file, and so on. Responsive to the analysis, the file distribution facilitator 181 can facilitate a further distribution of segments to one or more of the targeted wireless devices 124, 126 via the base station or access point 122 using licensed frequency spectrum. For example, the file distribution facilitator 181 can provide one or more of the missing segments to one or more of the targeted wireless devices 124, 126 in need of the missing segments. Alternatively or in addition, the file distribution facilitator 181 can provide one or more of the missing segments to other wireless devices 124, 126, relying on the P2P process to propagate the missing segments to the one or more of the targeted wireless devices 124, 126 in need of the missing segments.
This can include sending or seeding a missing segment to another wireless device of the targeted wireless devices 124, 126. Considering the user of selective distribution or seeding in combination with a P2P process, there is a likelihood that the other wireless device may have already received the missing segment. Accordingly, in at least some embodiments, the sending or seeding of the missing segment occurs after first determining that the intended recipient device has not already received the missing segment. It is understood that in at least some applications the initial sending or seeding of segments and/or the sending or seeding of missing segments can include sending or seeding segments to other wireless devices 124, 126 that may not be included in the targeted group of wireless devices 124, 126. This approach allows for a larger group of wireless devices 124, 126 to participate in the P2P process as facilitators. It is further understood that in at least some embodiments, participation of non-targeted wireless devices 124, 126 can be incentivized. By way of non-limiting example, incentives can include providing points, e.g., points that can be accumulated and used in a service provider's ecosystem or elsewhere, additional data that can be added to a subscribed data limit, and the like.
In at least some embodiments, at least some of the targeted wireless devices 124, 126 can analyze which data item segments it has and determines which data item segments it can upload to other peers according to the P2P process. In at least some embodiments, participants in the P2P process can include a client application. For example, the client application can seek out readily available data item segments, e.g., from peers, and download them immediately, rather than halting the download and waiting for the next (and possibly unavailable) piece in line, which typically reduces the overall time of the download. Some example client applications include, without limitation, μTorrent, Xunlei, Transmission, qBittorrent, Vuze, Deluge, BitComet and Tixati.
The data content source 202 provides a data content item to a file ingestor 204. The file ingestor 204 disaggregates, divides or otherwise partitions the data content item into a set of data item segments. It is understood that the data item segments have a size that is less than a size of the original data content item. In some embodiments, the data item segments are substantially equal in size, e.g., ten 1 Mb segments for a 10 Mb data content item. Alternatively or in addition, the data item segments of a disaggregated data content item can vary in size. Disaggregation can include any process that allows a data content item to be divided into segments or chunks that can be recombined to obtain the original data content item.
In some embodiments, a size of a data item segment can be fixed. Data content item segment, or chunk sizes can include, without limitation, a fixed number of bytes per segment, e.g., 1 Mb and/or a fixed number of segments per data content item, e.g., a number of “N,” say 10 segments per data content item or file, with a segment size being determined by a division of the data content item by the number of segments. It is understood that segment sizes can be selected based on one or more factors. Factors can include, without limitation, a type of data content item, e.g., streaming video versus text. Other factors can include network traffic conditions, type and/or capabilities of recipient devices, and the like. For example, a segment size may depend on a buffer size of a streaming media player. Alternatively or in addition, segment size may depend upon a quality of service requirement and/or a priority of the data item, e.g., with higher priority segments being assigned a greater or lesser size, such that a transfer requires coordination of fewer or more segments than a lower priority data item. Network traffic conditions can include, without limitation, network congestion, transport delay, signal-to-noise ration and/or bit error rate, error correction performance and so on. As network conditions may change, different segmentations may be selected based on the network conditions to facilitate efficient transfers of data content items.
It is further envisioned that in at least some embodiments, a size of a segment or chunk can vary. For example, multiple segment sizes for a different data content items can be fixed according to a particular segmentation and/or transfer strategy. A first segmentation of one data content item can be accomplished according to a first fixed segment size, whereas, a second segmentation of another data content item can be accomplished according to a second fixed segment size, which differs from the first. In at least some applications, segment size can vary for the same data content item. For example, a data content item can be divided into a number of segments, with at least some segments having different sizes than other segments. Segments can be transported according to a P2P process based on segment size. Some P2P participants may be selected based on segment size. Alternatively or in addition, segment size(s) may be selected based on the P2P participants. Selections of segment size and/or P2P participants can be based on one or more of the foregoing criteria, e.g., network conditions, data type, etc., and/or according to the P2P participants. For example, stationary or slow moving P2P participants may be selected for sharing a first segment size, e.g., a relatively large segment size, whereas, fast moving P2P participants may be selected for sharing a second segment size, e.g., a relatively small segment size. Accordingly, a data content item can be segmented according to multiple sizes to allow for implementation of a flexible P2P strategy.
In at least some embodiments, segment size can change during a P2P distribution process. For example, a data content item can be segmented according to a first segment size. The first segments can be distributed according a P2P process as disclosed herein. A file distribution facilitator can monitor progress of the file transfer and evaluate whether the process would be expedited according to a segmentation of a different size. To the extent that a different segment size would be beneficial, the distribution facilitator could initiate a different segmentation. It is envisioned that in at least some embodiments, that different segment sizes can be selected to be compatible.
In at least some embodiments, the ingestor 204 generates a segmentation record 207. The segmentation record 207, without limitation, can identify the data item segments of a disaggregated file. For example, the segmentation record 207 includes an identifier of the data content item as well as a segment reference number, e.g., a sequential or ordinal number, and the set of sequential or ordinal numbers identifying all data item segments of the associated data content item. The segmentation record can be used by one or more elements of the system 200 to track progress of a particular file distribution. The sequence number or ordinal reference can be used to arrange data item segments that may be received by a targeted wireless device out of order. The segmentation record and its entries are secured and signed in order to prevent tampering of data by other malicious entities.
In at least some embodiments, a security measure can be added to the process, e.g., to provide some assurance that data item segments received from peers are legitimate and authentic. According to the illustrative example, the file ingestor 204 applies a security mechanism to one of the data content item and/or the data item segments. Security mechanisms can include, without limitation, one or more of hash algorithms, checksums, encryption, blockchain, authentication and the like. In some embodiments, a data content item may be secured, e.g., by a security key to prevent unauthorized access. For example, distribution of copyright protected material may include some measure of scrambling that requires application of a key to obtain an unscrambled version. Such scrambling would allow peers of a P2P process to participate in a file distribution, without necessarily requiring access to the transferred data content item.
A blockchain-type, certification-type or Digital-Rights-Management-(DRM)-type of security measure can be applied to each of the data item segments. For example, the file ingestor 204 encodes each data item segment into a block of digital data that is uniquely signed and/or identified. According to a blockchain algorithm, each data item segment, or block, is connected to another block, such as the one before and/or after it. When applied in this manner, the blockchain algorithm can create an irreversible, immutable chain. Accordingly, data item segments, or blocks, are chained together, preventing any individual data item segment, or block, from being altered or an unauthorized block from being inserted between two existing blocks.
The system 200 also includes a file distribution facilitator 206. The file distribution facilitator 206 is in communication with the file ingestor 204 and one or more mobile cellular sites 208. In at least some embodiments, the file distribution facilitator 206 is in communication with the producer 202. Information obtained from the producer 202 can include identification of the data content item and identification of targeted recipients and/or targeted equipment of targeted recipients. In at least some embodiments, information obtained from the producer 202 can include identification of a priority, e.g., ranging from critical to trivial, uncritical or unimportant, e.g., “nice to have” but not necessary. In some embodiments, timing requirements for a file distribution can be imposed by the producer 202. For example, a safety related firmware upgrade to a vehicle may require full compliance within a time period, such as within 24 hours, within one week, etc.
In operation, the file distribution facilitator 206 identifies targeted wireless devices that should receive the data content item. The file distribution facilitator 206 also identifies the data content item to be distributed to the targeted wireless devices, the segmentation record, and any timing and/or priority requirements as may be related to the distribution. In some embodiments, the file distribution facilitator 206 determines a strategy for initiating, priming or seeding a P2P process. The strategy can be based on one or more of identification of the targeted wireless devices, a size of the data content item, a priority or criticality of the distribution and so on. In some embodiments, the file distribution facilitator 206 sends a complete set of all segments to a particular wireless device or group of wireless devices of the targeted wireless devices. Selection of the initial recipients can be based on one or more of a geographic location of the recipient wireless device, an available link quality associated with a wireless link to the recipient device, an identity of the particular wireless device, e.g., according to a type of device, a related user account. Other considerations can include, without limitation, whether a recipient device is a fast moving device, a slow moving device or a stationary device. For example, slow moving devices may be preferred over stationary devices to increase a likelihood of propagating segments to peers outside of a range of the participating cell.
In at least some embodiments, the recipient wireless device, e.g., a first auto 220, receives a copy of the segmentation record and updates a progress report 211a that identifies received segments, missing segments, or both received and missing segments. In some embodiments, the progress report 211a can be transmitted from the auto 220 back to the file distribution facilitator 206. Other participating wireless devices, such as a second car 222 can also maintain progress reports 211b, also providing an indication of transfer progress to the file distribution facilitator 206. The file distribution facilitator 206 can monitor file and/or segment distribution process based on the progress reports 211a, 211b, generally 221. Progress reports 211 can identify one or more of the wireless device, e.g., according to an IP address, a MAC address, a user account, a device type, and the like. The progress report can identify when a targeted wireless device has received a complete set of segments of a data item. The file distribution facilitator 206 can track completions, and terminate a P2P process when all or at least some predetermined portion of the targeted wireless devices have received the complete set of segments.
Once one or more participating wireless devices have received some or all of the data item segments of a particular data content item, a P2P process can be applied. The P2P generally allows for participating wireless devices to share one or more already received segments. The sharing can be accomplished according to a push algorithm, in which a participant having received one or more segments, i.e., a source, identifies participants within range and facilitates a transfer of one or more of the received segments. In some embodiments, a push algorithm includes sending messages from the source to other participants that identifies available segments. Recipient wireless devices can evaluate available segments against an associated progress report to identify missing segments. The recipient wireless devices can send a message to the source identifying missing segments.
By way of non-limiting example, the message can include a specific request for one or more of the missing segments. The source, in response, can supply the requested segments over a direct wireless link between the wireless devices 229 offloading the licensed cellular network. The wireless link 229 can include, without limitation, a wireless link operating in an unlicensed frequency band, such as forms of WiFi, millimeter wave, laser, or short-range communication technologies providing a radio interface for user equipment (UE) to UE communications. Without limitation, examples of short-range communication can include PC5 and/or alternative direct short range communication (DSRC), e.g., based on IEEE 802.11p. An example protocol is disclosed in 3GPP LTE-V2X PC5, also known as LTE side-link. Alternatively or in addition, the wireless link can include operation in licensed frequency spectra, e.g., according to Uu-air interface 226 between a UE 220 and an eNB 208. The eNB 208 can include functionality to identify and facilitate a wireless link to the requesting device. For example, the link can include traditional cellular communications, unlicensed frequency communications at network edge devices, such as wireless access points 210 or hotspots that can communicate to the requesting wireless device 222 in a wireless link 228 operating in unlicensed frequency bands. Alternatively or in addition, the eNB 208 can relay the communication to the file distribution facilitator 206, which identifies and/or facilitate a wireless link to the requesting device through one or more of the available wireless links 226, 229, 228. Furthermore, Road-Side-Units (RSU) type wireless endpoints such as 210 can be considered part of the supporting communication infrastructure. For example, RSUs 210 can include caching functionalities.
Alternatively or in addition, the sharing can be accomplished according to a pull algorithm, in which a participant having determined that one or more segments are required, i.e., a destination, identifies participants within range and facilitates a transfer of one or more of the received segments. In some embodiments, a pull algorithm includes sending messages from the destination to other participants that identifies missing segment(s). Hereby, data is exchanged in interest groups namely swarms for only one item represented by the segment lists or progress reports bilateral. In the example of
In at least some embodiments, one or more progress reports 211 are communicated to the file distribution facilitator 206. The file distribution facilitator 206, in turn, can evaluate missing segments for one or more destination devices of the targeted devices 220, 222 based on the progress reports 211. One or more of received information, e.g., progress reports and results of analyses can be stored in a P2P progress report 209. Having identified missing segment(s) and associated wireless devices, the file distribution facilitator 206 can further analyze progress reports 211, e.g., according to the P2P progress report 209, to identify potential source devices for serving the missing segment(s) to the destination devices. Any wireless device having already received a particular segment can serve as a source of that segment to other target devices missing the particular segment. In at least some embodiments, the file distribution facilitator 206 selects one or more sources for providing the missing segment(s) to the destination devices according to the P2P process. Selection of one or more sources can be based on position, location information, the proximity and/or channel quality between communicating instances determined individually and/or controlled by the eNB or swarm.
Position information can include, without limitation, a location of a source device, a location of a destination device, a relative location between the source and the destination device, or any combination thereof. Location information can be reported by one or more of the source and destination devices, e.g., according to a location application and/or GPS receiver of the device(s). Alternatively or in addition, location information can be determined by a wireless service provider. For example, locations can be determined according to distance or range estimates based on one or more of power level, time delay, time difference of arrival, phase difference, triangulations, and the like.
It is understood that in at least some embodiments, a network service provider can cache one or more segments, e.g., including complete sets of segments, at network edge locations. Edge locations can include, without limitation, wireless access points 210 mounted on RSUs 210 or deployed at alternative locations. At least some wireless access points provide wireless service to wireless devices 220, 222 via unlicensed frequency spectra, including any of the examples disclosed herein or equivalents. Caching can be used to supplement P2P distribution by providing wireless access to segments for destination devices of the targeted wireless devices is within wireless service range of the network edge device 210.
According to the illustrative example, the network edge device 210 is in communication with one or more of the file ingestor, 204 and file distribution facilitator 206. The network edge device 210 can participate as an injection point, e.g., similar to the cellular base station 208. Alternatively or in addition, the network edge device 210 can participate as a member of the P2P application, e.g., receiving and/or transmitting segments to other wireless devices of the group of targeted wireless devices. In at least some scenarios, the network edge device 210 is equivalent to a P2P device having a complete set of segments.
It is envisioned that distribution of at least some data content may be time critical. Accordingly, the illustrative systems discussed herein can include provisions that may decide whether to participate in the P2P process based on a timing aspect indicating a timing criticality having a relatively short time period. Alternatively or in addition, progress of an implemented P2P process can adapt according to a timing aspect. For example, if a timing aspect includes a maximum period for distribution to a group of targeted wireless devices, the system 200 may initiate distribution of the data content item according to a relatively limited seeding so as to reduce a burden to licensed frequency spectra. As time progresses, additional seedings may be necessary based on a remaining time of the maximum distribution period. It is conceivable that in at least some circumstances, Licensed frequency spectra can be used to distribute some or all segments missing as determined by the P2P process.
A first vehicle 236 includes at least one wireless device capable of communicating within an associated first wireless range 240. The wireless device can include a wireless transceiver of the car itself. Alternatively or in addition, the wireless device can include a wireless transceiver of an occupant or cargo, e.g., machine, of the vehicle 236. When the first vehicle 236 is within one of the regions of cellular coverage 234, it can communicate with equipment of the respective cell site 232 using licensed frequency spectrum. This communication allows the first vehicle to access cloud services, such as a P2P file distribution server, e.g., the file distribution facilitator 181 (
The first vehicle 236 moves according to a path 238 that may take the vehicle within and without one or more of the regions of cellular coverage 234. At some regions along the path 238, the first vehicle 236 may be in more than one regions of cellular coverage, e.g., being capable of communicating with both a first cell site 232a and a second cell site 232b. At other regions along the path 238, the vehicle falls outside of any of the regions of cellular coverage 234. It is understood that the illustrated regions of cellular coverage 234 may include in-network coverage, e.g., of a subscribed cellular service plan, and/or out-of-network coverage, e.g., of a competitor's cellular service plan.
According to the illustrative example, the first vehicle 236 is a targeted device of a group of targeted devices that are identified to receive a data content item. The data content item can be disaggregated into a set of data item segments as disclosed herein, and individual segments and/or groups of segments can be transported to the vehicle 236 according to the disclosed P2P process. For illustrative purposes, a segmentation record includes a set of boxes 242 representing a set of segments necessary for the first vehicle 236 to obtain the data content item plus one segment file indicating the amount of all segments and their certificates marked as ‘c’ in the first position of the boxes. Each segment represents one of the free boxes. The set of boxes 242 is not shaded indicating that all segments are required. However, as segments are received, the boxes of the set of boxes 242 are filled in. An arrow drawn from the first box of the set of boxes 242 to the cell tower 232a indicates that the first data item segment is received by the vehicle 236 when the vehicle 236 is within the first region of cellular coverage 234a. For the time being, the remaining boxes of the set of boxes 242 remain empty signifying that the vehicle 236 requires segments associated with the remaining unshaded boxes of the set of boxes 244.
The second system configuration 230b includes a second vehicle 246 located within the first cellular range 234a of the first cell site 232a and the second cellular range 234b of the second cell site 234b. The second vehicle has also received a segmentation record including a set of boxes 252 representing the set of segments necessary for the second vehicle 246 to obtain the data content item. The first and second sets of boxes 242, 252 can include the same boxes associated with the same segments and the same ordering necessary to regenerate the original data content item. However, the tracking of progress of received segments will vary according to the progress of the P2P process.
Being located within range of the first and second cell sites 232a, 232b, it would be possible for the second vehicle 246 to receive one or more segments from either or both of the cell sites 232a, 232b. However, a distribution of segments in this manner would utilize scarce licensed frequency spectrum of a Uu LTE link. Advantageously, proximity of the second vehicle 246 to the first vehicle 236 results in an overlapping coverage of the first wireless range 240 of the first vehicle 236 and a second wireless range 250 of the second vehicle 246. According to the illustrative example, both vehicles 236, 246 are participants in a P2P file sharing process. Accordingly, the first vehicle can share one or more segments that it has received. According to the illustrative example, the only segment that the first vehicle 236 can share is a first segment.
An arrow shown between the vehicles 236, 246 indicates a transfer of the first segment from the first vehicle 236 to the second vehicle 246. Beneficially, this vehicle-to-vehicle, i.e., P2P, transfer can occur in unlicensed spectrum based on the overlapping ranges 240, 250. Thus, a portion of the data content item corresponding to the first segment can be provided to the second vehicle without using the licensed frequency spectrum. Upon successful receipt of the first segment, the second set of boxes 252 can be updated to shade in the first box corresponding to receipt of the first segment. There is no change to the first set of boxes 242 being a donor in this instance. It is understood that in at least some instances a progress report, e.g., identifying received segments or shaded boxes, for each of the vehicles can be shared with other P2P participants and/or with the file distribution facilitator 181 (
The fourth system configuration 230d includes a third vehicle 247 also located outside of the first and second cellular ranges 234a, 234b. The third vehicle 247 has also received a segmentation record represented by a third set of boxes 253 corresponding to the set of segments necessary for the third vehicle 247 to obtain the data content item. The first and third sets of boxes 242, 253 can include the same boxes associated with the same segments and the same order to support regeneration of the original data content item. However, the tracking of progress of received segments of the first and third sets of boxes 242, 253 will vary based on their respective progress according to the P2P process.
Advantageously, proximity of the third vehicle 247 to the first vehicle 236 results in an overlapping coverage of the first wireless range 240 of the first vehicle 236 and a third wireless range 255 of the third vehicle 247. According to the illustrative example, both vehicles 236, 247 are participants in the P2P file sharing process. Accordingly, the first vehicle 236 can share up to the first two segments that it has received, while the third vehicle 247 can share a third segment that it has received.
A pair of arrows shown between the two vehicles 236, 247 indicates a transfer of the first and second segments from the first vehicle 236 to the third vehicle 247 and a transfer of the third segment from the third vehicle 247 to the first vehicle 236. After the mutual P2P transfer, both vehicles 236, 247 will have received the first three segments of the set of segments. Once again, the vehicle-to-vehicle, i.e., P2P, transfer can occur in unlicensed spectrum based on the overlapping ranges 240, 255 of the respective vehicles. Thus, a portion of the data content item corresponding to the first and second segments can be provided to the third vehicle 247 without using licensed frequency spectrum. Upon successful receipt of the first and second segments, the third set of boxes 253 can be updated to shade in the first three boxes corresponding to receipt of the first three segments. Likewise, the first set of boxes 242 can be updated to shade in the first three boxes corresponding to receipt of the first three segments.
Updated progress reports 242, 253, e.g., identifying received segments or shaded boxes, for each of the vehicles 236, 247 can be shared with other P2P participants and/or with the file distribution facilitator 181 (
The fourth system configuration 230d also illustrates a fourth vehicle 256. By this point in the illustrative example, the first vehicle 236 has already received first, second and third segments of the set of segments. A single segment remains to be received by the first vehicle 236 in order to complete the set of segments 242 allowing for a regeneration of the original data item at the first vehicle 236.
Advantageously, proximity of the fourth vehicle 256 to the first vehicle 236 also results in an overlapping coverage of the first wireless range 240 of the first vehicle 236 and a second wireless range 260 of the fourth vehicle 247. According to the illustrative example, both vehicles 236, 247 are also participants in the P2P file sharing process. Accordingly, the fourth vehicle 247 can share its fourth segment with the first vehicle.
An arrow shown between the vehicles 236, 247 indicates a transfer of the third segment from the fourth vehicle 247 to the second vehicle 246. It is understood that in at least some scenarios, a security measure is applied to one or more of the data content item segments. As disclosed above, the security item can be applied during a pre-processing of the data content item, e.g., coincident with disaggregation and/or after disaggregation but prior to initial injections or seeding by the mobile service provider. In such instances, security information can be generated to facilitate subsequent secure transfer and/or receipt of the data content item segments. The security information can include one or more of a checksum, a hash value, a key and/or other certificate.
In at least some embodiments, the security information is distributed to P2P participants. For example, the security information can be includes within a segmentation report, or provided separately. In at least some embodiments, the security information is distributed separately from the P2P process. Separate distribution can include, without limitation, distribution via licensed frequency spectra, e.g., via SMS, email, file transfer, and the like. In some embodiments, a P2P client application receives the security information from a P2P server application.
An arrow drawn from the fourth vehicle 256 to the first vehicle 236 indicates that the fourth data segment is transferred to the first vehicle to complete the set of segments. The first vehicle 236 upon receipt of the fourth segment, applies the security information to the received segment. However, according to the illustrative example, the fourth segment of a fourth group of blocks 232 of the fourth vehicle 256 has been compromised. Accordingly, application of the security information does not satisfy a security requirement of the security measure. For example, application of a hash algorithm produces a result that differs from a hash value. Accordingly, the first vehicle is unable to use the received segment to complete the set of segments.
In some embodiments, a recipient of a segment that does not satisfy a security requirement notifies a provider of the segment. The notification can request that the segment be resent. It is conceivable that the segment was corrupted during a wireless transfer from the fourth vehicle 256, e.g., due to noise, interference and/or a weak signal level. To the extent the segment is resent, the security information is applied once again. If the security measure fails, the process of resending and re-verifying can be repeated or terminated.
In some embodiments, a security report is generated to indicate that an attempted transfer or number of transfers of a data content item segment failed due to an inability to satisfy the security requirement. For example, a security report can be generated by the recipient, i.e., the first vehicle 236, by the provider, i.e., the fourth vehicle 256, or by both P2P participants 236, 256. The security report(s) can be shared with one or more P2P participants, with a with a mobile network operator, with a file distribution facilitator 181 (
It is understood that in at least some applications the security reports can be monitored, e.g., by any of the recipients or a dedicated security server, and analyzed to determine whether there will be any consequences the P2P distribution. For example, a report of the fourth segment failing a security requirement after transfer to the first vehicle 236 may result in the file distribution facilitator 181 taking action with respect to the provider, i.e., the fourth vehicle. Action might include resending the fourth segment to the fourth vehicle by any of the means disclosed herein including direct injection, e.g., by the second cell site 232b as the fourth vehicle 256 is within the range of cellular coverage 234b, or by P2P sharing from other participants, or any combination thereof. In some embodiments, the file distribution facilitator 181 and/or security server makes note of the security issue, but takes no immediate action. To the extent other security reports indicate security issues with one or more of the same segment or the same provider, e.g., the fourth vehicle 356, subsequent action may be taken. In extreme examples, the source of suspect data segments, e.g., the fourth vehicle 256, can be removed as a participant of the P2P file sharing. Removal can be for a current file transfer and/or from future file transfers.
An arrow drawn from the second vehicle 246 to the first vehicle 236 indicates that the fourth data segment is transferred to the first vehicle 236 to complete the set of segments. The first vehicle 236 applies the security information to the received segment and responsive to satisfaction of a security requirement, the P2P file transfer to the first vehicle is nearly completed. The first vehicle, having determined that it has received all of the segments according to the segmentation report, initiates a regeneration process. The regeneration process regenerates the original data content item from the complete set of received segments. Regeneration can include an aggregation of the segments of the complete set of segments. In at least some embodiments, regeneration instructions can be provided to P2P participants, such as the first vehicle 236 to facilitate application of the regeneration process by the first vehicle 236. For example, regeneration instructions can be provided by one or more of the file distribution facilitator 181 (
It is understood that regeneration of the original file may depend on a particular disaggregation process applied to the original data content item at a time of ingestion. It is conceivable that in some embodiments, more than one different types of disaggregation processes may be applied, e.g., according to a file size, a file type, a priority, network conditions, and the like. Alternatively, a common disaggregation process may be used, such that recipient devices do not require separate regeneration instructions. For example, file regeneration instructions or functionality can be built into a P2P client application allowing the file to be regenerated responsive to receipt of the complete set of segments. It is further conceivable that file regeneration may be performed having received less than a complete set, e.g., for streaming media wherein a sufficient set, being less than a complete set of segments, can be combined to regeneration of a portion of a streaming media file to allow for a presentation of that portion.
According to the process 260, a data item is identified for distribution at 261. Identification of the data item can include a request from a producer or provider of the data item. In at least some embodiments, the request is accompanied with or followed by receipt of the data item. The data item is segmented into a set of data item segments that are distributed individual or in groups to the equipment of the targeted group of users via a P2P file sharing process. The P2P process utilizes peer transfers of some data item segments in unlicensed frequency spectra blended with injection of other data item segments un licensed frequency spectra. The blended distribution provides for a timely distribution of the data item that limits use of licensed frequency spectra in an efficient manner.
A progress of P2P file distribution is monitored at 262. For example, progress can be determined according to individual progress reports from P2P participants. Progress reports can provide a measure of completion for each of the P2P participants, e.g., identifying received segments, missing segments, or some other measure, such as a percentage, or simple binary complete/incomplete. Progress can be tracked, e.g., by a file distribution facilitator 181 (
An efficiency of the P2P file distribution can be determined at 263. An efficiency can be based on any suitable measure, such as progress, segment availability, reachability, connectivity and signal quality, energy level, amount of transmitted/received files (to enforce fairness), elapsed time, remaining time, e.g., when a time limit has been established, ratio of licensed versus unlicensed spectrum, a percentage of licensed and/or unlicensed spectrum, and the like.
To the extent it is determined at 264 that the process 260 is progressing in an efficient manner, the process 260 continues monitoring the progress at 262 and analyzing and/or updating efficiency at 263. In some embodiments, trends and/or changes to progress and/or efficiencies can be determined and used as metrics to further evaluate a P2P file distribution process. For example, a trend in increasing or decreasing efficiency over time can trigger a response from a file distribution facilitator 181. If an efficiency is trending downward, i.e., becoming less efficient, than the file distribution facilitator 181 can revise and/or modify a segment injection policy. Such modifications might include injections of more file segments to offset a downward trend. Modifications can be reversed and/or further modified in a like manner. For example, if increased segment injection results in an increased efficiency, the file injections can be reduced to conserve licensed frequency spectra. It is understood that such a process can be automated, e.g., according to a feedback process to implement a predetermined policy responsive to P2P file transfer performance.
To the extent it is determined at 264 that the process is progressing in an inefficient manner, a segment is identified for injection at 265. Segment injection can include the use of licensed frequency spectra to inject one or more segments in a targeted manner, e.g., to specific users and/or within specific regions. For example, a location of the injection is identified at 266. The location might be a default location, e.g., every cell and/or cell sector, or a subset of cells and/or cell sectors. In at least some embodiments, targeted injection is based on a location of a P2P file distribution that requires one or more particular segments. In some embodiments, P2P progress can be arranged according to a geographical map to identify missing segments versus location. For example, a heat map can be prepared for an overall P2P progress/availability and/or progress of a group of segments. Such a mapping can be based on locations of equipment of the targeted group of users.
The segment is injected at the identified location at 267. The injection can be accomplished to one or more wireless devices within a coverage region of the identified location. For example, one P2P participant, or even a non-participant, can be identified as a destination for the injection. In at least some embodiments, the recipient can further distribute the injected segment according to the P2P process. The process again continues monitoring progress of the P2P distribution at 262.
A security measure is applied to the data item segments at 273. The security measure can include one or more of the example security measures disclosed herein or otherwise generally know. In at least some examples, the security measure can be applied by the file ingestor 180, 204. It is understood that more than one security measure can be applied. For example, an original data content item may be encrypted or otherwise scrambled before disaggregation. The individual segments resulting from disaggregation can be further secured, e.g., according to a hash, a checksum and/or a blockchain process. The security process includes provisions for receiving devices to apply security information to facilitate recovery of the original data item segments and/or file upon regeneration.
A first targeted wireless device is identified at 274. This can be any wireless device that happens to be within range of one or more cell towers of a mobile communication network. In some embodiments, the targeted wireless device is selected from among multiple devices according to a selection process. The selection process can include consideration as to whether the targeted wireless device is an in-network device, or roaming. Alternatively or in addition, the process can include consideration as to past performance of the particular device, e.g., if the device has been a reliable participant in other P2P file distributions. Still other considerations include types of equipment, signal strength, link quality, mobility, and so on.
In at least some embodiments a P2P push and/or pull process or algorithm monitors parameters that can be used in a selection process. Such parameters can include, without limitation, signal quality and/or channel quality between communicating instances (cell sites, RSUs, end user devices, vehicles, drones, and the like). Selection of a source and/or destination of a segment or group of segments can be based at least in part on the monitored parameters. In some embodiments, monitored parameters can include one or more of mobility, speed, direction, proximity, signal strength, channel quality and the like.
For example, a peer group can be established according to proximity, e.g., selecting peers within a geographical region, and/or within a radio signal range. Alternatively or in addition, peers of a group can be selected based on mobility versus stationary. Alternatively or in addition, peer groups can be selected based on a combination of parameters, such as mobility and direction. For example, a peer group can be selected to include vehicles moving in a similar direction. This might include vehicles traveling in the same/similar direction on the same roadway or different roadways in a same general direction. This would favor vehicles that are likely to remain within proximity for some time, versus vehicles moving in opposite or different directions.
A first secured data item segment is transported to the first wireless device at 275 via licensed frequency spectrum, e.g., according to a Uu protocol of a UE to eNB link of a 3GPP LTE (4G) network. The first secured data item segment distributed by the first wireless device to another wireless device via unlicensed frequency spectrum at 276. Transfer via unlicensed spectrum can include any of the examples disclosed herein, including short-range communication, Wifi, Bluetooth, and the like.
Progress of the P2P distribution progress is analyzed at 276 and a subsequent injection of a file segment is initiated at 278 responsive to the distribution progress.
While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks in
It is understood that in some instances, connectivity may be interrupted while transmitting one or more segments. This can include transmission by one or more of a mobile cellular site 208 232, an RSU 210, and/or equipment including mobile equipment of P2P participants and/or recipient devices 220, 222, 236, 246, 247, 256. Contributors to interruptions can include, without limitation, fading signals, distinct directions and/or loss of line-of-sight. A caching process can be employed by one or more of the P2P participants and/or recipients, such that portions of incomplete segments can be stored locally. Accordingly, an interrupted download of one or more segments can resume when conditions allow, completing transmission of segment(s) without necessarily re-transmitting any cached portions.

In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via a transport layer 350, a virtualized network function cloud 325 and/or one or more cloud computing environments 375. In various embodiments, this cloud networking architecture is an open architecture that leverages application programming interfaces (APIs); reduces complexity from services and operations; supports more nimble business models; and rapidly and seamlessly scales to meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations.
In contrast to traditional network elements—which are typically integrated to perform a single function, the virtualized communication network employs virtual network elements (VNEs) 330, 332, 334, etc. that perform some or all of the functions of network elements 150, 152, 154, 156, etc. (
As an example, a traditional network element 150 (shown in
In an embodiment, the transport layer 350 includes one or more of fiber, cable, free-space optical, e.g., laser, wired and/or wireless transport elements, e.g., Bluetooth and/or millimeter-wave for licensed and/or unlicensed spectrum, network elements and interfaces to one or more of the foregoing. The transport layer 350 can provide one or more of broadband access 110, wireless access 120, voice access 130, wireless P2P access 380, media access 140 and/or access to content sources 175 for distribution of content to any or all of the access technologies. In particular, in some cases a network element needs to be positioned at a specific place, and this allows for less sharing of common infrastructure. Other times, the network elements have specific physical layer adapters that cannot be abstracted or virtualized, and might require special DSP code and analog front-ends (AFEs) that do not lend themselves to implementation as VNEs 330, 332 or 334. These network elements can be included in transport layer 350.
The virtualized network function cloud 325 interfaces with the transport layer 350 to provide the VNEs 330, 332, 334, etc. to provide specific NFVs. In particular, the virtualized network function cloud 325 leverages cloud operations, applications, and architectures to support networking workloads. The virtualized network elements 330, 332 and 334 can employ network function software that provides either a one-for-one mapping of traditional network element function or alternately some combination of network functions designed for cloud computing. For example, VNEs 330, 332 and 334 can include route reflectors, domain name system (DNS) servers, and dynamic host configuration protocol (DHCP) servers, system architecture evolution (SAE) or its components such as mobility management entity (MME) or Packet/Serving-gateways, broadband network gateways, IP edge routers for IP-VPN, Ethernet and other services, load balancers, distributers and other network elements. In at least some embodiments, workloads of at least some elements can be distributed across a number of servers — each of which adds a portion of the capability, and overall which creates an elastic function with higher availability than its former monolithic version. These virtual network elements 330, 332, 334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.
The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc. to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.

The terms “first,” “second,” “third,” and so forth, as used in the claims, unless otherwise clear by context, is for clarity only and doesn't otherwise indicate or imply any order in time. For instance, “a first determination,” “a second determination,” and “a third determination,” does not indicate or imply that the first determination is to be made before the second determination, or vice versa, etc.
In the subject specification, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can comprise both volatile and nonvolatile memory, by way of illustration, and not limitation, volatile memory, non-volatile memory, disk storage, and memory storage. Further, nonvolatile memory can be included in read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can comprise random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory.
Moreover, it will be noted that the disclosed subject matter can be practiced with other computer system configurations, comprising single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as personal computers, hand-held computing devices (e.g., PDA, phone, smartphone, watch, tablet computers, netbook computers, etc.), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network; however, some if not all aspects of the subject disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
In at least some embodiments, a file sharing process, such as the example processes disclosed herein, can include a revoking of content distributed according to the P2P file sharing. A revocation process can be accomplished in a manner similar to the provisioning processes disclosed herein, such that provisioned content can be revoked, terminated and/or otherwise purged from P2P participants. For example, revocation can be initiated according to a planned distribution period and/or lifecycle of data/content. It is understood that a revocation process can be applied to all segments of a data item and/or in a selective manner to a subset of segments of the data item. For example, an updating process can be applied to replace and/or add a scene of a movie, a chapter of a book, and/or a subset or module of provisioned software and/or firmware. Outdated portions may be excised from the P2P process, as necessary, and replaced with updated content, while leaving other portions subject to an earlier P2P process unmodified. Whether an updating process or a replacement process is applied can be determined, e.g., according to estimates of bandwidth usage, time to complete, network conditions, and so on. For example, to the extent it is determined that it would be easier to insert a new item instead of updating existing ones, the process would proceed to revoke the old item in favor of the new one.
In one or more embodiments, information regarding use of services can be generated including services being accessed, media consumption history, user preferences, and so forth. This information can be obtained by various methods including user input, detecting types of communications (e.g., video content vs. audio content), analysis of content streams, sampling, and so forth. The generating, obtaining and/or monitoring of this information can be responsive to an authorization provided by the user. In one or more embodiments, an analysis of data can be subject to authorization from user(s) associated with the data, such as an opt-in, an opt-out, acknowledgement requirements, notifications, selective authorization based on types of data, and so forth.
Some of the embodiments described herein can also employ artificial intelligence (AI) to facilitate automating one or more features described herein. The embodiments (e.g., in connection with automatically identifying acquired cell sites that provide a maximum value/benefit after addition to an existing communication network) can employ various AI-based schemes for carrying out various embodiments thereof. Moreover, the classifier can be employed to determine a ranking or priority of each cell site of the acquired network. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, . . . , xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to determine or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches comprise, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
As will be readily appreciated, one or more of the embodiments can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to predetermined criteria which of the acquired cell sites will benefit a maximum number of subscribers and/or which of the acquired cell sites will add minimum value to the existing communication network coverage, etc.
