METHOD AND APPARATUS FOR ROUTING MESSAGES IN A NETWORK

摘要

A method of routing a message in a network includes transmitting by a mobile station (105) a signaling connection establishment message (308) on a radio connection (118) to a radio network control (102) though a base station (104). The signaling connection establishment message including a registration request message. Next the mobile station receives a registration accept message (310) on the radio connection and subsequently transmits an uplink signaling message (312) on the radio connection. The uplink signaling message from the mobile station includes a core network operator identifier (604).
