  • Patent number: 8725831
    Abstract: A two-layer communication protocol that supports efficient real-time location-aware application on multiple mobile devices that must communicate with each other and/or a centralized server. The two-layer protocol includes a method of communicating data between a first mobile device and a second mobile device using a server to facilitate the communication of the data. The two-layer communication protocol also includes a method of communicating data between a first mobile device and a second mobile device using a server to facilitate the connection between the two devices. The communication of data occurs directly between the two mobile devices. Each method uses reliable, connection-oriented protocols to exchange application-level information and control signals while utilizing unreliable, connection-less protocols to communicate real-time location data. Also provided are architectures implementing these methods.

  • Patent number: 8718015
    Abstract: Disclosed are a method and a terminal for synchronizing a subordinate carrier cell, which method comprises the following steps of: after a terminal receives an activation uplink subordinate carrier order from a service node B, the terminal, with the current time as a reference, carrying out synchronization in a cell in an activation set of the enhanced dedicated channel of the subordinate carrier under a non-service node B at a first time point after having carried out delay according to an acquired subordinate carrier activation processing offset time period. The present technical solution reduces the time delay required by synchronization and inter-cell interference and enables the cell capacity and coverage to be unaffected.

  • Patent number: 8705456
    Abstract: A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.

  • Patent number: 8700034
    Abstract: Systems and methods are disclosed that provide identities of multiple serving elements of user equipment (UE). In one embodiment, a subscriber server of a packet-switched data network stores data for the UE, which is served by the packet-switched data network. The subscriber server receives a user data request from a network element over a Diameter interface. In response to the user data request, the subscriber server identifies multiple serving elements where the UE is presently registered in the packet-switched data network and/or a legacy network. The subscriber server inserts identifiers for the multiple serving elements where the UE is presently registered in a user data answer, and transmits the user data answer to the network element over the Diameter interface.

  • Patent number: 8699488
    Abstract: A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet that includes a feature header. The device also modifies, based on the feature peer information, current condition state signaling, and other information, the feature header to create a modified customer packet, and determines, based on the feature peer information, the current condition state signaling, and the other information, which of the feature peers support a feature associated with the modified customer packet. The device further selects, from the determined feature peers, a set of feature peers for the modified customer packet to traverse, and forwards, based on the modified feature header, the modified customer packet to one of the feature peers in the selected set of feature peers.

  • Patent number: 8693366
    Abstract: Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.

  • Patent number: 8681690
    Abstract: A technique for enabling multiple terminals to simulate data traffic of a single virtual terminal includes transmitting from a first transmitting terminal a request to establish a communication session between the first transmitting terminal and a receiving terminal, where the first transmitting terminal is one a plurality of transmitting terminals. The first transmitting terminal receives at least one message from the receiving terminal to establish the communication session. Once the communication session is established between the first transmitting terminal and the receiving terminal, data traffic is transmitted from the plurality of transmitting terminals to the receiving terminal within the communication session such that the receiving terminal is unaware that more than one transmitting terminal is transmitting within the communication session.

  • Patent number: 8665708
    Abstract: The present invention provides a method and an apparatus for acquiring protocol messages by a ring-network node, including: using dual fields to identify different protocol messages; if a node supporting G.8032v1 receives a Force Switch (FS) or Manual Switch (MS) protocol message, determining that message is a Signal Fail (SF) protocol message according to an identifier; a node supporting G.8032v2 determining that the received protocol message is an SF or MS or FS protocol message according to the identifier. The method of the present invention enables the nodes in a ring network to accurately control the state of their own ports, thereby avoiding the case that multiple blocking points appear in the ring network and improving the network performance.
