Abstract
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.
Claims29
A femto cell base station used in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- generating means that generates a SIP (session initiation protocol) message including a terminal ID of a radio terminal and a check request for the terminal ID at a predetermined time;
- and
- first transmitting means that transmits the SIP message generated by said generating means to a higher level apparatus in said communication system.
A gateway system that forms a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- first determining means that determines which an apparatus is a destination based on whether a received SIP (session initiation protocol) message includes information indicating a check request for a terminal ID or information indicating a SMS (short message service) when the gate way system receives the SIP message;
- and
- third transmitting means transmits content of the received SIP message to the destination determined by said first determining means.
A MAP (mobile application part) gateway apparatus used in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- second determining means that determines whether or not a received message includes information indicating a check request for a terminal ID;
- and
- fourth transmitting means that transmits a message corresponding to the received message including the check request to said equipment identification register in a case where said second determining means determines that the received message includes the information indicating the check request for said terminal ID.
A communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- A femto cell base station used in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- generating means that generates a SIP (session initiation protocol) message including a terminal ID of a radio terminal and a check request for the terminal ID at a predetermined time;
- and
- first transmitting means that transmits the SIP message generated by said generating means to a higher level apparatus in said communication system;
- A gateway system that forms a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- first determining means that determines which an apparatus is a destination based on whether a received SIP (session initiation protocol) message includes information indicating a check request for a terminal ID or information indicating a SMS (short message service) when the gate way system receives the SIP message;
- and
- third transmitting means transmits content of the received SIP message to the destination determined by said first determining means;
- and
- A MAP (mobile application part) gateway apparatus used in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- second determining means that determines whether or not a received message includes information indicating a check request for a terminal ID;
- and
- fourth transmitting means that transmits a message corresponding to the received message including the check request to said equipment identification register in a case where said second determining means determines that the received message includes the information indicating the check request for said terminal ID.
A communication control method in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- a generation step of a femto cell base station generating a SIP (session initiation protocol) message including a terminal ID of a radio terminal and a check request for the terminal ID at a predetermined time;
- and
- a first transmission step of said femto cell base station transmitting the SIP message generated in said generation step to a higher level apparatus in said communication system.
A communication control method in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- a first determination step of determining which apparatus is a destination based on whether a received SIP (session initiation protocol) message includes information indicating a check request for a terminal ID or information indicating a SMS (short message service) when a gateway system forming said communication system receives the SIP message;
- and
- a third transmission step of said gateway system transmitting content of the received SIP message to the destination determined in said first determination step.
A communication control method in a communication system having a function of checking a terminal ID through the use of an equipment identify register, comprising:
- a second determination step of a MAP (mobile application part) gateway apparatus in said communication system determining whether or not a received message includes information indicating a check request for a terminal ID;
- and
- a fourth transmission step of said MAP gateway apparatus transmitting a message corresponding to the received message including the check request to said equipment identification register in a case where it is determined in said second determination step that the received message includes the information indicating the check request for said terminal ID.
