Integration of Packet and Cellular Telephone Networks
First Claim
1. Communication apparatus, comprising:
- a packet network interface, for coupling to a packet switch in a packet network;
a telephone network interface, for coupling to a node in a circuit-switched telephone network; and
a convergence processor, coupled between the packet network and telephone network interfaces and adapted to emulate a mobile switching center (MSC) and a visitor location register (VLR) in the circuit-switched telephone network so as to assign telephone numbers in the circuit-switched telephone network to user terminals in the packet network and to connect telephone calls, using the assigned telephone numbers, between telephones in the circuit-switched network and the user terminals.

Abstract
Communication apparatus (22) includes a packet network interface (62), for coupling to a packet switch (28) in a packet network (24), and a telephone network interface (63), for coupling to a node (54) in a circuit-switched telephone network (26). A convergence processor (66) is coupled between the packet network and telephone network interfaces and adapted to emulate a mobile switching center (MSC) and a visitor location register (VLR) in the circuit-switched telephone network so as to assign telephone numbers in the circuit-switched telephone network to user terminals (30, 32, 34, 38) in the packet network and to connect telephone calls, using the assigned telephone numbers, between telephones (42) in the circuit-switched network and the user terminals. 51617

16. A method for communication, comprising:
-
coupling a convergence processor between a packet switch in a packet network and a node in a circuit-switched telephone network;
assigning telephone numbers in the circuit-switched telephone network to user terminals in the packet network; and
connecting telephone calls, using the assigned telephone numbers, between telephones in the circuit-switched network and the user terminals, by operating the convergence processor so as to emulate a mobile switching center (MSC) and a visitor location register (VLR) of the assigned numbers in the circuit-switched telephone network. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
