  • Patent number: 9596709
    Abstract: A method, device, and computer program product for facilitating device-to-device, D2D, communication among wireless communication devices, WCDs, is provided. The device is a first WCD that receives a wireless packet broadcasted by a second WCD. The wireless packet has one or more of i) a group identifier that identifies a group to which the second WCD belongs and ii) an application identifier that identifies an application which generated at least part of the wireless packet. The first WCD extracts from the wireless packet one or more of the group identifier and the application identifier. The first WCD determines whether to discard the wireless packet based on the one or more of the group identifier and the application identifier extracted from the wireless packet.

  • Patent number: 9408113
    Abstract: A method of selecting a target core network of a communication network for handing over a voice session of a terminal from a packet switched source radio access network (RAN) to a target RAN. The voice session is anchored in an Internet Protocol Multimedia Subsystem, and the selected target core network includes a circuit switched domain which is associated with the target RAN and supports voice session continuity to hand over the voice session from the source RAN to the target RAN. The target RAN is associated with a network identification of the target core network. The method is executed by a node and includes receiving a network identification of at least one target core network associated with at least one target RAN. The target core network is selected based on an indicated support of voice session continuity by the network identification.

  • Publication number: 20160165565
    Abstract: A quite simple and effective way for simplifying the mobile system for the mobile broadband customers, thereby lowering the equipment costs and in the end allowing for more competitive flat rate fees, is to direct the traffic from mobile broadband devices (110) to dedicated gateways (120). The mobile broadband device (110) is comprised in a user equipment (105) in a wireless communication network (100). The wireless communication network (100) comprises a network node (115) is arranged to be connected to the mobile broadband device (110). First, the mobile broadband device (110) sends (200, 300) an attach request message to the network node (115). The attach request comprises an information element indicating that the device (110) is a broadband device. Then, the device (110) receives (301) an attach accept message from the network node (115) comprising address information of the dedicated gateway (120).

  • Patent number: 9258179
    Abstract: A method is provided for facilitating recovery from the failure of a P-CSCF within an IP multimedia Subsystem network. A gateway, such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway responds by signalling the unavailability of the P-CSCF to user equipment, which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF.
