Abstract (en)

[origin: WO0160091A1] A system for interworking voice signaling messages between circuit-switched and packet-switched networks includes a base station (24) operable to communicate with a mobile station (12) over a wireless interface (48). The system also includes a wireless adjunct internet platform (WARP) (26) coupled to the base station (24) and to the packet-switched network (20). The WARP (26) is operable to communicate with the mobile station (12) through the base station (24) using a circuit-switched call control protocol and with the packet-switched network (20) using a packet-switched call control protocol. The WARP (26) comprises an interworking function operable to convert between the circuit-switched call control protocol and the packet-switched call control protocol.
