An authentication system comprises a register image storage unit, which stores a pre-registered register image of a mobile terminal user; a communication control unit, which receives a moving image of the user transmitted from the mobile terminal; and an authentication processing unit, which authenticates the user by checking the moving image received by the communication control unit against the register image stored in the register image storage unit.

Authentication system, mobile terminal, and authentication method

When a location-area MSCreceives an SMS originating signal, an interrogating unitsends an SRIforSM signal including the MSISDN of a receiving terminalto an HLRWhen the location-area MSCreceives an SRIforSMack signal from the HLRa subscriber-identification-information obtaining unitobtains an IMUI contained in the SRIforSMack. An on-origination carrier identifying unitidentifies from the IMUI the carrier to which the receiving terminalsubscribes. The location-area MSCdetermines whether the carriers have an SMS interconnection agreement with each other, on the basis of identification made by an on-origination carrier identifying unit

A mobile communication service control system according to the present invention has a home location registerstoring subscriber information, a switching unitfor sending a subscriber information inquiry signalto the register, and a service control unitfor controlling a service provided for subscribers. The home location registerstores service informationnecessary for a start of control of the service at the service control unitand sends the service informationalong with a response signalto the subscriber information inquiry signalto the switching unit. The switching unittransfers the service informationreceived from the register, to the service control unit
