摘要:
A communication system that includes at least UE and an HLR that are used in an IMS network further includes: a Femto-cell base station that makes up a predetermined communication area, and a control unit for controlling at least communication between the UE and the HLR. The Femto-cell base station and the control unit are present between the UE and the HLR. The Femto-cell base station includes a transmission unit for transmitting messages received from the UE to the control unit and for transmitting messages received from the control unit to the UE. The control unit converts messages received from the Femto-cell base station to messages that can be recognized by the HLR, and converts messages received from the HLR to messages that can be recognized by the UE.

摘要:
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.
摘要:
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.

摘要:
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.
摘要:
A communication system for solving a problem, in which secure communications security cannot be ensured in communications between a femtocell base station and UE, is provided. The communication system includes UE (User Equipment) and an HLR (Home Location Register) used in an IMS (IP Multimedia subsystem) network and a femtocell base station (Femto AP) that constructs a predetermined communication area. The femtocell base station exists between the UE and the HLR, acquires a concealment key corresponding to the UE from the HLR during authentication of the UE, and executes a concealment process to conceal the identity of the UE based on the concealment key.
