PROBLEM TO BE SOLVED: To enable communication between a user handling an originating terminal and an extension terminal over a mobile communications network, using operations that are simple by the user. SOLUTION: An HLR 30 associates the originating terminal specification information of the originating terminal 10, the representative number of a local area communication device 50 connected by the originating terminal 10 and the extension number of the extension terminal connected by the local area communication device 50, and stores them in a connectivity-restriction storage 31. A connection request receiver 41 of a call controller 40 acquires the representative number on the basis of the originating terminal specification information and the extension number of a call receiving terminal 60, while referring to the connectivity restriction storage 31 when a connection request including the originating terminal specification information and the extension number of the call receiving terminal 60 is received through the mobile communication network N from the originating terminal 10. The connection request receiver of the call controller, further, transmits a connection request with an identifier indicating a direct-in connection request to the local area communication device 50. The local area communication device 50 receives the connection request and enables communication over a local area communication network E with the call-receiving terminal 60, when it is confirmed that the connection request has the identifier.
