  • Patent number: 9705906
    Abstract: Physical Layer and Data-Link Layer data are connected with Networking through Application Layer data/information to enable searching, sorting, and identification of novel relationships between signal sources and their contents. Metadata can be used at the Physical Layer in an optical fiber network, connecting with metadata generated at the Data Link Layer, connected to metadata generated at the Network to Application Layer. The Physical Layer metadata is obtained from configuration and provisioning data within an Intelligent Optical System. The Data-Link Layer metadata is obtained from a signal processing device. The Network through Application Metadata is obtained from a packet capture or flow capture probe. The metadata from all layers are linked in a data store such that the network traffic, passing through stream(s) in optical fiber(s) layer data are combined.

  • Patent number: 9647759
    Abstract: A method for communication includes receiving in a first communication interface input frames, which include data symbols that were derived by encoding respective characters, and further include one or more synchronization symbols having no corresponding characters. The characters from the data symbols are recovered, and the recovered characters are transmitted to a second communication interface by mapping the characters into communication frames and discarding the synchronization symbols. The characters are extracted from the communication frames in the second communication interface by synchronizing to the input frames independently of the synchronization symbols. The input frames are reconstructed in the second communication interface, including the data symbols and the synchronization symbols, by re-encoding the extracted characters.

  • Patent number: 9647782
    Abstract: We disclose an interface device configured to inter-convert CPRI data frames and Optical Transport Units (OTUs). The interface device acquires frame synchronization by temporarily storing data in a buffer bank such that translated sync characters are placed at respective predetermined locations within the buffer bank. Each translated sync character represents, in the corresponding OTU, a respective sync character of a CPRI hyperframe. The interface device is configured to distinguish translated sync characters from payload-data words of identical value based on predetermined alignment, in the buffer bank, of data temporarily stored therein for conversion into the CPRI data format. The interface device advantageously enables multiplexing of a plurality of CPRI links and aggregation and encapsulation of the multiplexed CPRI data into a stream of OTUs for transmission to the intended destination over an Optical Transport Network.

  • Patent number: 9519608
    Abstract: PCI Express is a Bus or I/O interconnect standard for use inside the computer or embedded system enabling faster data transfers to and from peripheral devices. The standard is still evolving but has achieved a degree of stability such that other applications can be implemented using PCIE as basis. A PCIE based interconnect scheme to enable switching and inter-connection between multiple PCIE enabled systems each having its own PCIE root complex, such that the scalability of PCIE architecture can be applied to enable data transport between connected systems to form a cluster of systems, is proposed. These connected systems can be any computing, control, storage or embedded system. The scalability of the interconnect will allow the cluster to grow the bandwidth between the systems as they become necessary without changing to a different connection architecture.

In one embodiment, a base station determines that the base station is transitioning to an unavailable state. The base station then notifies one or more radio network nodes with which the base station conducts base-station-to-node communication that the base station is unavailable. Thereafter, in one embodiment, the one or more radio network nodes cease communication attempts with the base station. In this manner, the radio network nodes can avoid spending additional resources on attempts to re-establish communication connections to base stations that tend to be offline more often (e.g., low-power base stations (LP-BSs)).

  • Patent number: 9037145
    Abstract: A first mobile station operating on a first network according to a first network protocol receives a proxy request for access to a network resource, by from a second mobile station operating on a second network according to a second network protocol. The proxy request is received according to a third network protocol. The first mobile station determines a priority of the proxy request; accepts or denies the proxy request based on the determined priority of the proxy request; allocates resources to the proxy request, if the proxy request is accepted; and serves as a proxy mobile station for the second mobile station to access the network resource.

  • Patent number: 9025605
    Abstract: Apparatus and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.

  • Patent number: 9014196
    Abstract: Messages from a physical layer of each communication band and communication channel associated with each protocol utilized in a multi-band, multi-protocol network may be aggregated into a single multi-protocol layer called, for example, a super channel layer. An optimal communication path may be identified from among the communication bands and/or communication channels based on information borne by the single multi-protocol layer. A communication session may be established via optimal communication path. The communication path may include different channels within a single communication bands, and/or channels selected from different communication bands. In this regard, channels from the same or different communication bands may be combined to provide an optimal communication path. The single multi-protocol layer may be characterized as a sublayer located within the data link layer. Accordingly, the single multi-protocol layer may be located above a MAC layer, both of which are part of the data link layer.

  • Patent number: 9007908
    Abstract: A system and method for remote and mobile patient monitoring service is provided using heterogeneous wireless access in which each patient is equipped with a remote monitoring device with a heterogeneous wireless transceiver. This can be a value-added service provided by a Healthcare service provider (i.e., a hospital or healthcare center) for which the Healthcare service provider can pay to the wireless network service provider (i.e., a network operator). With heterogeneous wireless access, a remote/mobile patient can use different types of wireless technologies (e.g., WiMAX-based WMAN and WiFi-based WLAN technologies) to transfer monitored bio-signal data to the healthcare center. The monitoring device can buffer and then transmit the bio-signal data to the healthcare center through the heterogeneous radio access network. In this device, there can be two buffers used to store bio-signal data, each with different priority. The scheduler in this device can make an optimal decision on data transmission.
