ABSTRACT:
The mobile communication network (30) comprises at least one circuit switching access network (33) that supports circuit switched communications. A call control system (23) for providing call related functions for packet switched communications, arranged to send and receive call control information in accordance with a first call control protocol (SIP) for packet switched communication, is provided. An access control system (22) is arranged to exchange call control information with said call control system (23) by using said first call control protocol (SIP), and to exchange call control information with said circuit switching access network (33) by using a second call control protocol (RANAP/BSSAP).
