The road to 3G runs through 2G and 2.5G networks. Until 3G is deployed ubiquitously, 2-2.5G networks and endpoints dominates. The 3G subscribers should share the successful services deployed in the existing network and the service migration is needed. Redesigning and redeveloping the legacy services is a time-consuming and error-prone task. A connection view model (CVM) approach is taken to simplify the service migration. Services represented with the CVM are platform independent and the main task is to develop the transform rules for service migration which can be reused. With this approach, the successful color ring back tone (CRBT) service is migrated to the IP multimedia subsystem (IMS).
