Femtocell base station, gateway system, map-gw apparatus, communication system, control method, and program

A femtocell base station that connects UE (User Equipment) to a core network side, the femtocell base station characterized by comprising

• control means for controlling ON and OFF of a flag used in controlling whether a SMS (Short Message Service) reaches the destination.

A gateway system that transfers, via a femtocell base station that connects UE (User Equipment) to a core network side, a short message to the UE, the gateway system characterized by comprising

• transfer means for, in the case where a SIP (Session Initiation Protocol) message is received, transferring, when the received SIP message is transmitted to a SMSC (Short Message Service Center), content of the SIP message to the SMSC and transferring, when the received SIP message is transmitted to a destination other than the SMSC, the content of the SIP message to an apparatus on the core network side.

A MAP (Mobile Application Part) gateway apparatus used in a communication system having a function of delivering a short message, the MAP gateway apparatus characterized by comprising

• control means for transmitting, when MS Present information or SMMA (Short Message Memory Available) information is included in a received message, a message corresponding to the MS Present information or the SMMA information to a HLR (Home Location Register).

A communication system comprising at least UE (User Equipment) and a femtocell base station that connects the UE to a core network side, characterized in that

• the femtocell base station includes
• control means for controlling ON and OFF of a flag used in controlling whether a SMS (Short Message Service) reaches the destination.

A communication system comprising UE (User Equipment), a femtocell base station that connects the UE to a core network side, a SMSC (Short Message Service Center) that manages a short message delivered to the UE, and a gateway system that transfers the short message to the UE via the femtocell base station, characterized in that

• the gateway system includes transfer means for, in the case where a SIP (Session Initiation Protocol) message is received, transferring, when the received SIP message is transmitted to the SMSC, content of the SIP message to the SMSC and transferring, when the received SIP message is transmitted to a destination other than the SMSC, the content of the SIP message to an apparatus on the core network side.

A control method performed in a femtocell base station that connects UE (User Equipment) to a core network side, the control method characterized by comprising:

• a first transmitting step of converting, when information concerning a SMS (Short Message Service) is received from the UE, the received information concerning the SMS into a SIP (Session Initiation Protocol) message including the received information concerning the SMS and transmitting the converted SIP message to the core network side;
• and
• a second transmitting step of converting, 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 transmitting the converted information concerning the SMS to the UE.

A control method performed in a femtocell base station that connects UE (User Equipment) to a core network side, the control method characterized by comprising:

• a control step of controlling ON and OFF of a flag used in controlling whether a SMS (Short Message Service) reaches the destination.

A control method performed in a gateway system that transfers, via a femtocell base station that connects UE (User Equipment) to a core network side, a short message to the UE, the control method characterized by comprising

• a transfer step of, in the case where a SIP (Session Initiation Protocol) message is received, transferring, when the received SIP message is transmitted to a SMSC (Short Message Service Center), content of the SIP message to the SMSC and transferring, when the received SIP message is transmitted to a destination other than the SMSC, the content of the SIP message to an apparatus on the core network side.

A control method performed in a MAP (Mobile Application Part) gateway apparatus used in a communication system having a function of delivering a short message, the control method characterized by comprising

• a control step of transmitting, when MS Present information or SMMA (Short Message Memory Available) information is included in a received message, a message corresponding to the MS Present information or the SMMA information to a HLR (Home Location Register).
