Abstract
An apparatus (105), system (100) and method is provided for a unified circuit switched and packet-based communications system architecture having network interworking functionality. The apparatus (105) includes a circuit switched network interface (130), with the circuit switched network interface coupleable to a network switch (135) for communication of a circuit switched network protocol signal with a circuit switched network (160); a packet-based network interface (140), the packet-based network interface coupleable to a router (115) for communication of a packet-based network protocol signal with a packet-based network (150); a transceiver (120) coupleable to the communications channel (103) for the transmission and reception of a first protocol signal; and a communications controller (145), the communications controller coupled to the circuit switched network interface, to the packet-based network interface and to the transceiver, the communications controller responsive, through a set of program instructions and an interworking function, to interconvert the first protocol signal with the circuit switched network protocol signal and to interconvert the first protocol signal wi…
