Abstract
A communication system and communication method with which an incoming call processing can be prevented from falling into a loop state when a communication mode for the incoming call destination is determined. When an inquiry reception unit receives an inquiry signal representing an incoming call destination inquiry from a GMSC, a flag judgment unit judges whether an identification flag has been added. In cases where judgment is made that an identification flag has not been added, a response unit sends back a routing number of a CCCF/NeDS assigned to the GMSC and, in cases where judgment is made that an identification flag has been added, a VMSC inquiry unit acquires in-range information regarding the mobile device from a VMSC which is a visited mobile-services switching center, and the acquired in-range information acquired by the response unit is sent back to the GMSC.
