When a femto cell base station used for a communication system provided with a function of providing a predetermined supplementary service receives first information indicating supplementary service control from a radio terminal, the femto cell base station converts the received information to a SIP (Session Initiation Protocol) message including the first information and transmits the SIP message to a higher apparatus in the communication system.

Communication system and apparatus for providing supplementary service in femto cell

A femto cell base station includes a generating part that generates a SIP message including a terminal ID of a radio terminal and a check request for the terminal ID at a predetermined time, and a first transmitting part that transmits the SIP message generated by the generating part to a higher level apparatus in the communication system.

Communication system for checking for unauthorized use of a terminal

A femtocell base station (FAP) converts, when information concerning a SMS is received from UE (User Equipment), the received information concerning the SMS into a SIP (Session Initiation Protocol) message including the received information concerning the SMS and transmits the converted SIP message to the core network side. The femtocell base station converts, when a SIP message including information concerning the SMS is received from the core network side, the information concerning the SMS included in the received SIP message into a message that can be recognized by the UE and transmits the converted information concerning the SMS to the UE.
