  • Patent number: 9088960
    Abstract: A network architecture uses an Application Server Autonomous Access (ASAA) server which allows paging and call routing across different types of wireless and wireline access networks. The ASAA server provides connectivity between an external voice or data network and a wireless transmit/receive unit (WTRU). The external voice or data network may be a public switched telephone network (PSTN) or a public data network (PDN), so that the connectivity between the external network and the WTRU is provided through the access networks using data from the ASAA server.

  • Patent number: 8971293
    Abstract: The present invention is a method and system for station location based neighbor determination and handover probability estimation. A serving access point determines the location and movement measurements of a station (STA). Neighboring access points report coordinates of cell fringes of the neighboring access points. The STA sends a request for system information to the current access point along with current location of the STA. The current access point provides the system information, and the STA utilizes the system information to determine best handover candidate from among neighboring access points and an estimate of the time for handover.

  • Patent number: 8219091
    Abstract: A method and system for conveying media independent handover (MIH) capability information are disclosed. A wireless communication system includes a plurality of wireless networks deployed under different wireless communication protocols. A multi-mode wireless transmit/receive unit (WTRU) may perform a handover from one wireless network to another for continuous reception of services. The wireless network sends a message to the WTRU which indicates whether the wireless network supports MIH services and a supported MIH mode. The WTRU receives the message and makes a handover decision based on the message.
