Patent ID: 7054302

Claim:
The An arrangement for interworking a time division multiple access (TDMA) network with a plurality of non-TDMA networks, the arrangement comprising: voice signaling gateway (VSGW) means coupled to the plurality of non-TDMA networks and to the TDMA network, said VSGW comprising a session initiation Protocol (SIP) element and a dispatch application (DAP) element, wherein the voice signaling gateway (VSGW) means further includes: a VSGW signaling controller for generating signaling information for the TDMA network and the plurality of non-TDMA networks; a VSGW bearer traffic controller for converting bearer traffic between the TDMA network and the plurality of non-TDMA networks; the coupling of the VSGW means to the TDMA network including a plurality of connections for signaling and for bearer traffic; and the coupling of the VSGW means to the plurality of non-TDMA networks including signaling and bearer traffic connections between each of the plurality of non-TDMA networks and the VSGW means, wherein the VSGW signaling controller is coupled to the VSGW bearer traffic controller via a bearer control connection whereby the VSGW signaling controller controls bearer traffic interworking via the VSGW bearer traffic controller among the TDMA network and the plurality of non-TDMA networks.
