Abstract
The present invention provides a system and apparatus for a mobile CS user to access an IMS network and a registration method for accessing. The network under the present invention comprises an IMS network for providing IMS services and a CS access network. The network contains a Register Proxy Function (RPF) entity, which comprises a first interface for communicating with the IMS network and a second interface for communicating with the CS access network. The RPF entity is adapted to map a CS registration event which is originated by the mobile CS user through the second interface to an IMS registration event, and initiate registration to the IMS network through the first interface on behalf of the mobile CS user. The technical solution under the present invention enables a mobile CS user to be registered to an IMS network practicably so that the CS user can enjoy rich IMS services.
