Abstract:
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.
