摘要 |
A wireless communications system and methods having at least two interconnected Mobile Switching Centers (12, 14), each coupled to a corresponding media gateway (74, 76) and to an IP network (40) reduces the use of circuit connections (32) during inter-MSCs handover. Speech packets (84) are transmitted between a first MSC (12) and a second MSC (14) over an IP network (40) rather than over the circuit connections (32). An IP address (80) is used as a transaction identifier which can include the IP address, socket, and/or session number associated with the media gateway (74) for a call. The anchor MSC (12) sends the IP network address (80) that is currently being used for the call to the non-anchor MSC (14).
