COMMUNICATION SYSTEM, GATEWAY DEVICE, FEMTO ACCESS POINT, COMMUNICATION METHOD AND DEVICE PROGRAM
First Claim
1. A communication system which is connected to another communication system with a different communication procedure and is used, whereinthe other communication system comprises an RNC (Radio Network Controller) and a BTS (Base Transceiver Station);
- the communication system comprises a gateway device and a Femto Access Point;
the gateway device and the Femto Access Point configure a virtual RNC unit which is recognized as an RNC by the RNC when communication with the RNC is performed; and
if hand over is performed between the BTS and the Femto Access Point, the virtual RNC unit transmits and receives a message containing hand over information for call control to and from the RNC.

Abstract
In order to realize hand over between an existing communication network and an FAP in a communication system with a different communication procedure, without requiring improvement of an existing communication system, a gateway device and the Femto Access Point configure virtual RNC means which is recognized as an RNC by an RNC when communication with the RNC is performed, and if the hand over is performed between a BTS and the Femto Access Point, the virtual RNC means transmits and receives a message containing hand over information for call control to and from the RNC.
