Abstract:
1. A mobile communication method in a mobile communication system providing switched type communications by which a mobile station currently camping on in a cell under control of a radio access network of a first communication scheme not supporting circuit-switched communications is enabled to be switched to a cell under control of a radio access network of a second communication scheme supporting the circuit-switched communications to start the circuit-switched communications, the method comprising the steps of: causing a mobile station to send a switch of the first communication scheme a call request signal including capability information indicating whether or not the mobile station supports a barring scheme for the switched type communications; causing the switch to perform processing regarding the switched type communications for the mobile station when receiving the call request signal during call restriction and judging that the mobile station supports the barring scheme for the switched type communications on the basis of the capability information; and causing the switch to send the mobile station a call rejection signal when receiving the call request signal during the call restriction and judging that the mobile station does not support the barring scheme for the switched type communications based on the capability information.
