Abstract: Apparatus and methods for access point coordination of data transmissions within a wireless local area network (WLAN). In one embodiment, a method of managing a WLAN using an access point (AP) coordination system. The AP coordination system accepts client device requests through their associated APs and coordinates one or more APs within the WLAN to fulfill the client requests, without forcing the client devices to associate with different APs. The APs fulfilling a client device request are masked under the BSSID of the client-associated AP.

Abstract: A wireless station is allocated use of a time slot in a given direction, uplink or downlink, on a given channel. The wireless station monitors for presence of wireless energy during a portion of the time slot. Based on a detected level of the wireless energy in the time slot, the wireless station controls transmission of wireless communications in a direction opposite to the configured direction in a remaining part of the time slot.

Abstract: A system and method for mitigating a distributed denial-of-service (DDoS) attack in a networked computing system. At least one DDoS honeypot in operative communication with a central controller in the networked computing system is configured to receive a data packet from a network, determine a source address of the data packet, and send the source address to the central controller. The central controller is configured to initiate a mitigation action based on the source address and one or more mitigation rules, wherein a determination of whether the received data packet is part of the DDoS attack is based on one or more detection rules.

Abstract: Methods and apparatus for reducing base station downlink transmission power in a manner that provides one or more devices being serviced by the base station time to establish or switch to another connection are described. The methods and apparatus are particularly well suited for system where base stations may be instructed by a control device to reduce or stop downlink power to a point where downlink data transmission is not supportable. In various embodiments a base station responds to a downlink power reduction instruction by reducing downlink transmission power in downlink slots in a serious of power reduction steps. In cases where the required power reduction is to a point where downlink data transmission can not be supported, the base station signals that it is switching to a no DL slot mode of operation in which downlink slots are not supported but UL slots will continue to be supported.

Abstract: In a wireless communications system, such as a 5G CBRS system, a Spectrum Access System (SAS) assigns portions of the (CBRS) spectrum to associated base stations (CBSDs). In some embodiments, a central spectrum-database server receives information about spectrum allocations made by two or more different SASs operated by different companies and tabulates that information in a combined spectrum database that each SAS can independently retrieve for use in allocating bandwidth to its CBSDs. In some implementations, the messages between each SAS and multiple associated CBSDs are transmitted via a domain proxy that snoops on multiple spectrum-allocation-related messages (e.g., spectrum grant/revocation messages and/or heartbeat messages) to gather the information to be transmitted to the server, where the information does not include any company-or network-sensitive information.

Abstract: Systems, methods, and devices for establishing a context-centric shared-viewing party. A processor in a network server may determine content for shared viewing based on inputs received from a user via a user device, and select a context participant group. Each of the user and participants in the selected group may share a commonality with the other participants in that group. The processor may receive complementary context from at least one or more of the user device or user devices of participants in the selected group. The processor may generate a context stream based on the received contextualized content, and send the context stream to the user device.

Abstract: A master node (MN) communicating with a UE using resource of a first band of unlicensed spectrum sends an addition request to a selected secondary node, to request resources for supporting the UE in a second band of unlicensed spectrum. The addition request includes minimum frequency separation information and optionally a baseline reference frequency. The minimum frequency separation information communicated in the addition request, indicates a minimum amount of frequency separation to be maintained between the communication resources in the first band of unlicensed spectrum used for communications with the UE and communication resource in the second band of unlicensed spectrum to be used for communications with the UE. The secondary node selects a channel within the second band of unlicensed spectrum to use for communications with the UE, which will satisfy the minimum frequency separation requirement communicated in the addition request and avoid IDC problems for the UE.

It is determined that the first object comprises a first network-attached device attached to a network. Information that corresponds to the first network-attached device is obtained, and the information is presented in conjunction with a real time view of the scene.

Abstract: Redundant configuration and testing for flexible nodal layer 3 overlay of layer 2 traffic. A network deployed at a site includes a local network to carry layer 2 traffic, a pair of layer 3 tunnel instantiation devices in a failover configuration. Each layer 3 tunnel instantiation device encapsulates the layer 2 traffic into layer 3 traffic and forwards the layer 3 traffic to a network gateway using a configurable layer 3 tunnel. A virtual client on each layer 3 tunnel instantiation device sends simulated client traffic to the network gateway via the local network and a partner layer 3 tunnel instantiation device to check end-to-end operability of the local network, the partner layer 3 tunnel instantiation device, and the network gateway. A testing layer 3 tunnel instantiation device initiates an action with respect to the partner layer 3 tunnel instantiation device based on a response to the simulated client traffic.

Abstract: Methods and apparatus used to facilitate preparation of one or more target base stations for possible UE handoffs, e.g., conditional handoffs, which may or may not occur depending on whether or not various handoff conditions are satisfied are described. A handoff message, e.g., a conditional handoff message, including a validity time is generated and sent to each selected target base stations to which a UE may be handed off. The validity time indicates to the target base station a time window, e.g., a time duration for which the handoff target message is to be considered valid. In response to the handoff message, the target base station, receiving the handoff message, allocates resources to the UE and starts a countdown validity timer based on the indicated length of the validity time. When the validity timer expires without handoff to the target base station, the target base station releases the allocated resources.

Abstract: According to one configuration, a system includes a mobile communication device in communication with a wireless base station. During operation, the mobile communication device detects one or more conditions associated with the wireless network environment. Based on the one or more detected conditions, the mobile communication device selects amongst multiple channel access procedures to communicate with the wireless base station and establish a wireless communication link. The mobile communication device can be configured to include supplemental data in a message to the wireless base station to indicate a reason for the mobile communication device selecting a particular channel access procedure of the multiple channel access procedures.

Abstract: A video processing system receives primary video capturing movement of a first object, the first object defined in the primary video by multiple contours of the first object. The video processing system receives selection information indicating a contour of interest associated with the first object; the contour of interest may be one of the multiple contours of the first object. Based on the selection information, the video processing system monitors the contour of interest. The video processing system analyzes variations in the monitored contour of interest over multiple frames of the primary video to produce magnified motion associated with the monitored contour of interest of the first object.

Abstract: A network services provider delivers bandwidth services to users in relation to a dynamic limit based on an average user consumption, rather than a fixed amount per subscriber. An average user consumption is employed to compute a consumption limit from relative portions of a user community substantially exceed the average, typically defined as “heavy users.” Usage levels below the consumption limit have an increased availability up to the consumption limit. The consumption limit may vary from a total capacity of the service infrastructure, which changes, generally in an increasing manner, as additional resources are added to the network. The consumption limits may be defined over different service intervals, such as daily, weekly or monthly, and for different groups of users depending on network layout.

Obtain, by the controller, from a plurality of peering entry points of the internet service provider, currently used bandwidth per customer for the plurality of internet service provider customers. Compare, by the controller, for the plurality of internet service provider customers, the assigned bandwidth per customer to the currently used bandwidth per customer, to determine at least one given customer of the plurality of internet service provider customers putatively suffering from a distributed denial of service attack. Initiate at least one remedial action for the at least one given customer of the plurality of internet service provider customers putatively suffering from the distributed denial of service attack.

Abstract: Methods and apparatus for determining and adjusting subcarrier spacing (SCS) to be used by a base station, e.g., a CBSD, for transmitting downlink data to one or more wireless devices, e.g., UEs, are described. A subcarrier spacing (SCS) level to be used by the base station is determined based on information relating to buffering of downlink data supplied to the base station via a cable, e.g., data accumulation rate (DAR) and/or average data arrival time (ADAT). Measured cable modem (CM) to base station latency is also used in the SCS determination. The amount of time for which a determined SCS level is to be used by the base station is set based on measured latency between a CMTS and the CM.

Abstract: Methods and apparatus for predicting communications resources which will be needed at a venue and then controlling the amount of available resources dynamically are described. In various embodiments real time or near real time video of areas of the venue are used to predict the number of people in a portion of a venue and/or the direction of movement. Along with other information such as the type of event and/or event schedule collected information is supplied to a set of trained resource requirement models which are used to predict future resource needs at a venue, e.g., while an event is ongoing. Commands are sent to dynamically vary the amount of communications resources provided to one or more portions of the venue. Resources which can be varied included but are not limited to fixed wired WAN bandwidth, WiFi bandwidth, cellular bandwidth, network based on-demand services, transcoding services, firewall services, etc.

Abstract: Apparatus and methods for managing content delivery in a packetized network. In one embodiment, the network provide content to a plurality of clients via a plurality of nodes and origin points, and resources are discreetly represented (e.g., with IP addresses, such as those afforded under the IPv6 protocol) to allows for direct advertisement of resources. Exemplary solutions described herein further advantageously leverage extant architectures and protocols (such as BGP), and make use of a common control plane, which can be utilized for example by different content delivery network (CDN) operators and different delivery components to advertise resources. Internally within a given CDN, increased granularity of resource addressing and advertisement may provide benefits including: (i) resource affinity; (ii) resource-level balancing; (iii) dynamic resource scoping; and (iv) “zero-touch” provisioning and resource relocation.

Abstract: A Narrow Band-Internet of Things (NB-IoT) communications link between a wireless access point of a non-cellular network and a cellular base station of a cellular network is implemented and used to support load management operations in a communications system including a cellular network and a non-cellular network. A service management system uses UE performance information and network statistics communicated over the NB-IoT communications link to evaluate network loading with regard to congestion in the non-cellular network. The session management system initiates a communications session for congestion control to offload a session from a congested network to a less congested network. The NB-IoT link is used to communicate session handoff related signaling.
