    Abstract: PROBLEM TO BE SOLVED: To provide inter-system handoffs between an existing circuit wireless system and a packet system by an improved wireless network. SOLUTION: A packet wireless system is enhanced so as to provide translation between a circuit call model and a packet call model. A media gateway translates bearer traffic between formats used in each system. The media gateway, a media gateway control function and an associated call state control function cooperate to emulate the behavior of the circuit wireless system, so that when interoperating with a conventional circuit wireless system, the packet system appears to be another circuit wireless system. When necessary, the media gateway, the media gateway control function and the call state control function are more cooperated with each other in order to emulate the function of an anchor MSC of the circuit wireless.

    Abstract: An application server component of an apparatus in one example communicates to one or more mobile stations, of a plurality of mobile stations, one or more updates of one or more statuses of respective one or more mobile stations of the plurality of mobile stations. The plurality of mobile stations comprise a first mobile station and a second mobile station, wherein the one or more updates of the one or more statuses of the respective one or more mobile stations comprise an update of a status of the first mobile station. The application server component communicates the update of the status of the first mobile station to the second mobile station to indicate to the second mobile station whether the first mobile station is available for participation in a call with the second mobile station.
