METHOD AND APPARATUS FOR PROVIDING CIRCUIT SWITCHED DOMAIN SERVICES OVER A PACKET SWITCHED NETWORK

摘要

A method and apparatus for providing mobile switching center based services over a packet switched network is described. An interface between a mobile station and a packet mobile switching center is provided. The interface is used to transfer control plane information and user plane information between the mobile station and the packet mobile switching center over the packet switched network. A packet mobile switching center for a circuit switched network is also described. In one embodiment, a network controller handles control plane information from a packet switched core network and an interworking unit handles user plane information from the packet switched core network.
