  • Patent number: 9357078
    Abstract: An SS7-based call protocol conversion gateway that translates between circuit-switched SS7 protocols and session initiation protocol (SIP) oriented protocol, allowing an E911 call initiated over a switched network to be routed by a VoIP network. The SS7-based call protocol conversion gateway provides a PSAP with MSAG quality (street address) information about a VoIP dual mode phone user without the need for a wireless carrier to invest in building out an entire VoIP core. Thus, wireless carriers may continue signaling the way they are today, i.e., using the J-STD-036 standard for CDMA and GSM in North America, yet see benefits of a VoIP network core, i.e., provision of MSAG quality location data to a PSAP.

  • Patent number: 9357578
    Abstract: Methods, systems, and devices are described for recovery from a connection disruption of a user equipment (UE) operating in a multi-carrier mode. The UE may establish a first connection with a primary cell and a second connection with a secondary cell while operating in the multi-carrier mode. A determination may be made that a disruption in the connection with the primary cell has occurred, and the UE may perform a connection reestablishment procedure to attempt to reestablish communications. The connection reestablishment routine may prioritize the secondary cell ahead of one or more other cells for attempting to reestablish communications. The prioritization may be based at least in part on the establishment of the second connection in the multi-carrier mode.

  • Patent number: 9295014
    Abstract: When performing interference cancellation on selected information (e.g., synchronization signals, certain broadcast signals, etc.) through cross correlation, symbol periods of signals being combined will generally match up. Slight mismatches will generally produce negligible impact on interference cancellation. However, where the mismatch is severe due to significant timing offsets, serious performance degradation may occur, particularly when timing offsets are sufficiently large as to overlap data portions of a transmission. By selectively puncturing resource elements prior to the selected information and/or after the selected information, the selected information may be protected and allow for interference cancellation even in cases of large timing offsets.

    Abstract: A system and method for neighbor-cell measurement reporting in a cellular environment supporting multistate cells limits measurement reporting by requiring that state-specific trigger conditions are met. Thus for example, a dormant cell may need to meet more stringent measurement conditions before a report is generated by the user device, since a current primary cell may prefer to hand off to an active cell. In particular, state-specific thresholds, offsets, and hysteresis values may be used to enforce a preference for active cells, for example.

Thus, the network may take advantage of opportunities for handover or cell reselection offered by a detected cell, while still insuring that handover or cell reselection procedures remain limited to cells that are appropriate.

  • Patent number: 9198093
    Abstract: A method of facilitating identification of a user equipment (UE) is disclosed. A first network control node (NCN) receives an radio link failure (RLF) indication message including a first mobile identity indicator (MII) of a UE. The first NCN determines a second MII of the UE, the second MII being associated with the first MII, and a second NCN associated with the second MII. And the first NCN sends the second MII to the second NCN.

  • Patent number: 9198122
    Abstract: System and method are provided for redirecting a communication device between a macro network and a femtocell network using a service redirection message (SRDM). In an embodiment, the communication device registers with the network which then determines the subscription status of the communication device to a femtocell network. If the subscription is confirmed, using the SRDM the system redirects the communication device to a communication frequency used by the femtocell network. Upon receipt of the SRDM, the communication devices tunes to a communication frequency specified in the SRDM. The system may segregate the CDMA channels used by the macro network, one set containing channels exclusive to the macro network and the other containing channel or channels used by both the macro network and the femtocell network. In this way, the communication device is prevented from entering a frequency re-hashing loop.

  • Patent number: 9191872
    Abstract: There is provided a passive network monitoring device that monitors one or more network interfaces between network nodes including a SGW node, a PGW node, an ePDG node, and a PCRF node and a PCEF node. The device receives a handover indication for UE from untrusted non-3GPP network access to 3GPP network access and receives a response to an attach request from one or more of the network interfaces, the response including a MSIP address and a charging ID for the UE. The device determines the UE is from a single subscriber based on each of the handover, the MSIP address of the response and the charging ID of the response, and correlates information for the UE at each of the one or more network interfaces with the single subscriber.

  • Patent number: 9191869
    Abstract: A device receives a default cell handoff parameter set from a base station within a cellular network. The device receives a modified handoff parameter set, wherein the modified handoff parameter set is different than the default cell handoff parameter set, and tests a mobile device in different geographic locations served by the base station, using the modified handoff parameter set, to measure one or more network/call service parameters associated with handoff of the mobile device to a neighboring cell. The device identifies optimum modified handoff parameters for the mobile device based on the measured one or more network/call service parameters.

  • Patent number: 9191094
    Abstract: A relay node (200) transmits a terminal handover request, which requests permission for a terminal handover, or a relay station handover request, which requests permission for a relay station handover, to a radio base station (100A). When the relay node receives a handover instruction which instructs a relay station handover, the relay node carries out a relay handover; and when the relay node receives a handover instruction which instructs a terminal handover, the relay node transmits the handover instruction to at least one among a group of radio terminals (300E-300G).

    Abstract: A map-based mobility robustness optimization (MRO) capability is provided for improving one or more aspects related to mobility in a wireless communication network. The map-based MRO capability may use one or more reference signal strength map associated with a wireless network to determine at least one management function for the wireless network. The at least one management function may include determining at least one configuration action adapted to satisfy a handover failure rate for the wireless network based on the one or more reference signal strength maps, preventing handover race conditions in a cluster of wireless cells covered by the one or more reference signal strength maps, or the like. The one or more management functions may be adapted to improve or optimize one or more of handover failure rate, prevention of handover race conditions, or the like.
