The attributes of IMS common centrex service are very similar to that of intelligent network VPMN in TD-SCDMA/GSM network, and the service for group client will mainly be provided by the common centrex service in the future. To preserve the investments in existing SCP equipment, it is suggested that a gradual upgrade should be carried out to incorporate the current SCP platform into the common centrex service platform. As networking of multi-manufacture may come into being on the platform upon the upgrade of equipment, this paper will give a comprehensive and detailed study on networking of multi-manufacture IMS commom centrex service platform incorporated with VPMN.
