  • Patent number: 9357586
    Abstract: In a communication network (400), wireless access points (300) utilize one or more agents (302, 306) to support the operating needs of corresponding mobile stations. Pursuant to one approach, the agent supports translation of the mobile station's end-to-end protocol-based messages to Internet Protocol-based messages that are readily ported through an Internet Protocol-friendly communication system infrastructure that preferably eschews the use of network elements that rely upon unique and/or proprietary non-Internet Protocol interfaces. Pursuant to another approach the wireless access point is able to interact on a peer-to-peer basis with other wireless access points in order to facilitate, for example, handovers and other mobility management tasks.

  • Patent number: 8401574
    Abstract: A method and apparatus for managing delivery of information in a wireless network (100) includes bearer plane information handlers (110, 111), each of which maintains a database of paging controller associations (200). Each paging controller association is an association of an idle mobile device to a last known paging controller of that idle mobile device. The apparatus also includes paging controllers (115-118), each of which is associated with at least one paging area (130-133). For each paging area, the paging controller maintains a database of all base transmitters of the paging area that are associated with the paging controller (310) and maintains a database of other selected paging controllers that control base transmitters in the paging area (315). Using these resources, the method uses location notification messages and paging responses to deliver bearer plane information to a mobile device (125) that has been idle.

  • Patent number: 8374153
    Abstract: Various embodiments are described to enable improved inter-network/inter-technology handover of mobile devices. A network device (131, 132) collects dynamic information corresponding to mobile devices (101, 102), such as wireless measurement information at the device's location, and/or information corresponding to wireless network nodes (121-124), such loading levels/loading distributions. The network device then sends some or all of the dynamic information collected and/or statistical information generated from the dynamic information collected to a neighboring network information server (150) for access by other communication networks. By maintaining dynamic and/or statistical information in a neighboring network information server, such information can be made available to all the communication networks in a given region. One potential benefit to making this information available is improved inter-network handoff decision-making.
