Abstract:
The characteristic of a mobile communication system according to the present invention is that the mobile communication system includes the steps of: causing an MME in a visitor network of UE#1 to acquire SRVCC capability of the UE#1 and to notify an HSS of the SRVCC capability of the UE#1 in an attach process or location registration process of the UE#1; and causing an ATCF, which controls an ATGW, to acquire the SRVCC capability of the UE#1, in a registration process of the UE#1 with IMS.
