INTEGRATION SYSTEM OF DIFFERENT TYPES OF MOBILE SWITCHING CENTERS AND SUPPORTING METHOD AND APPARATUS

摘要

An integration system using multiple types of MSCs (12, 14) has been provided. An access request from a mobile station (22, 24, 26) is first determined (36) whether it is associated with a second type of MSC. If so, the access request is routed (38) to a MSC of the second type. Otherwise, it is determined (42) whether the access request is a registration, and if so, the access request is also routed (38) to a MSC of the second type for the registration processing. At the registration process, it is determined (82) whether the access request should be associate with the second type of MSC, and if so, an association as such is assigned (86) between the mobile station and the second type of MSC.
