  • Patent number: 8483173
    Abstract: A media gateway comprising a plurality of network interface cards, at least one switch matrix, and a server module including at least one unlicensed mobile access module is provided. A method and computer-readable medium for activating an unlicensed mobile access channel for a mobile station in a network is provided. A media gateway receives a request to allocate an unlicensed mobile access termination. The request is received in response to at least one of a discovery registration by the mobile station and a handover request by the mobile station. The mobile station is serviced by at least one of a wireline network and a wireless network interfaced by the media gateway. The media gateway allocates the unlicensed mobile access termination. The termination has an identifier associated therewith. The media gateway receives at least one transmit parameter associated with the mobile station, and completes bearer set-up of the unlicensed mobile access channel according to the at least one transmit parameter.

  • Patent number: 7835346
    Abstract: Methods, systems, and computer program products for establishing transcoding free connections between UMA and UMTS call legs are disclosed. According to one method, a media gateway determines whether codec configurations used by UMA and UMTS legs of a call are compatible. In response to determining that the configurations are compatible, media gateway determines whether rate control is necessary to establish a transcoding free connection. In response to determining that rate control is necessary, the media gateway issues rate control requests on the UMA and UMTS legs as appropriate. The media gateway determines whether the rate control requests are successful. In response to determining that the requests are successful, the media gateway establishes a transcoding free connection between the UMA and the UMTS legs of the call.

  • Patent number: 7729346
    Abstract: Methods and apparatus for transparently switching a local instance of a UMTS protocol-based call from a first card or module of a media gateway to a second card or module of the media gateway, such that the remote end of the call is not aware that the call has been switched between the first and second cards or modules. Moreover, initially establishing call media flow may include implementing two timers of different duration during which call-initialization is retried if no Positive-Acknowledgement of call initialization is received, where a shorter-duration timer is relied upon to attempt retries if a Negative-Acknowledgement is received, and a longer-duration timer is relied upon to attempt retries if neither a Positive-Acknowledgement nor a Negative-Acknowledgement is received.
