摘要： Embodiments provide efficient multicast handover for content delivery to client devices in multi-carrier communications systems. For example, client devices in a transport craft can consume a media channel offering via a first carrier during transport through the communications system. Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second.

摘要： A first network node controls WLAN accesses and a second network node controls cellular network accesses. The first network node (NN) records a time of a last radio contact event of a user equipment (UE) with respect to a WLAN access controlled by the first NN. In response to a request from a third NN, the first NN indicates the recorded time of the last radio contact event to the third NN. The second NN records a time of a last radio contact event of the UE with respect to a cellular network access controlled by the second NN. In response to a request from the third NN, the second NN indicates the recorded time of the last radio contact event to the third NN. The third NN can use the indicated times to determine whether the UE is attached to a WLAN access or to a cellular network access.

摘要： Wireless access points detect neighboring wireless access points in different subnets. Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information. If so, the neighboring wireless access point uses the predictive roaming information to quickly connect with the wireless client and to establish a tunnel to redirect network traffic associated with the wireless client through to its home subnet.

摘要： A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

摘要： Systems, methods, and instrumentalities to select a distributed gateway (D-GW). A WTRU may be configured to detect a request for an address associated with content. The WTRU may receive an address list associated with the content. The WTRU may select a distributed gateway (D-GW). If an address of a currently connected D-GW is included in the address list, the WTRU may select the currently connected D-GW. If the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the WTRU may select the anchor D-GW that is not currently connected. If the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the WTRU may select the currently connected D-GW.

摘要： A method and apparatus are described for supporting dynamic and distributed mobility management (DMM). A wireless transmit/receive unit (WTRU) may attach to a first distributed gateway (D-GW), and configure a first Internet protocol (IP) address based on a prefix locally provided by the first D-GW. The WTRU may move and attach to a second D-GW while carrying out an on-going communication session with a correspondent node (CN). The WTRU may configure a second IP address based on a prefix provided by the second D-GW. The WTRU may use the first IP address for carrying out the on-going session and use the second IP address for a new communication session.

摘要： Embodiments of the invention are directed to systems, methods and computer program products for routing traffic in a packet data network (PDN). A method includes determining whether the mobile device has an active long-lived data traffic session over an original PDN connection between the mobile device and a first PDN gateway (P-GW); if the mobile device has an active long-lived data traffic session, then routing any new long-lived data traffic session over the original PDN connection; and if the mobile device does not have an active long-lived data traffic session, then routing any new long-lived data traffic session over a location-based PDN connection established based at least in part on a current location of the mobile device. In other words, the mobile device initiates and maintains all long-lived data sessions (for which service continuity is essential) to only one PDN connection.
