COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

A communication system and method not causing a call arrival processing to come into a looped state when the communication method at the called side is determined. When an inquiry receiving section (201) receives an inquiry signal indicating an inquiry of the called side from a GMSC (101), a flag judging section (202) judges whether or not an identification flag is added. If not, a reply section (205) sends as a replay a routing number RN of a CCCF/NeDS (105) allocated by an allocating section (204) to the GMSC (101). If so, a VMSC inquiry section (203) acquires visit information on the mobile device from a VMSC (107) serving as a visit exchange, and sends the visit information acquired by the replay section (205) to the GMSC (101) as a replay.
