  • Implementing generic cell global identity for unlicensed mobile access
    Patent number: 7885638
    Abstract: A method for causing GSM location information and UMA billing information to be encapsulated in a single CGI structural element during a standalone UMA network access session comprises a plurality of operations. An operation is provided for applying at least one algorithm to location information of a Mobile Station (MS) serving a subscriber device during a standalone UMA network access session for causing at least one of compressing, re-aligning and repackaging the MS location information whereby an amount of MS location information holding space of a GSM Edge Radio Access Network (GERAN) Cell Global Identity (CGI) structural element occupied by the MS location information is reduced such that a portion of the MS location information holding space becomes unused. An operation is performed for inserting UMA billing information into at least a portion of the unused portion of the MS location information holding space.

  • Method and system for providing wireless-specific services for a wireless access network
    Patent number: 7639647
    Abstract: A method and system for providing wireless-specific services for a wireless access network includes receiving at a call agent of a wireless access network a call origination for a mobile device. Whether the device is registered on the wireless access network is determined. If the mobile device is not registered, whether the mobile device is active is determined at a mobility control function (MCF). If the mobile device is active, the call is connected to the mobile device with a call agent based on a temporary line directory number (TLDN) assigned by the MCF and passed to the call agent in an extended session initiation protocol (SIP) message.

  • Method and system of control signaling for a wireless access network
    Patent number: 7471674
    Abstract: A method and system of control signaling for a wireless access network includes receiving from a wireless access network a signaling message for a mobile device. The signaling message is in a wireless-specific format. The signaling message is converted to a native format of a call agent to generate a call agent message. The call agent message comprises wireless-specific information of the signaling message.

  • Method and system for providing supplementary services for a wireless access network
    Patent number: 7444151
    Abstract: A method and system for providing supplementary services for a wireless access network includes downloading supplementary service triggers from a call agent to a mobility control function (MCF) for a wireless access network. Wireless-specific signaling of the wireless access network is communicated to the MCF. The MCF detects events associated with a trigger based on the wireless-specific signaling. The call agent is informed of the events by the MCF through session initiating protocol (SIP) extensions.
