Patent ID: 8903417

Claim:
A mobile terminal comprising: circuitry configured to receive information adapted to a current location of the mobile terminal via a mobile communication network from an information service providing communication apparatus that sends information adapted to current locations of mobile terminals to mobile terminals; transmit signals to the information service providing a communication apparatus; identify a location of the mobile terminal; calculate a linear movement distance of the mobile terminal between a past location of the mobile terminal and a current location of the mobile terminal; determine whether the linear movement distance is greater than a threshold; transmit a signal indicating the current location of the mobile terminal if it is determined that the linear movement distance is greater than the threshold, and not transmit the signal indicating the current location if it is determined that the linear movement distance is less than the threshold; store the past location of the mobile terminal; determine that transmission of the signal indicating the current location has been successfully completed when an acknowledgement of the signal indicating the current location is received; determine that transmission of the signal indicating the current location has failed when the signal indicating the current location cannot be transmitted, or an acknowledgement is not received although the signal indicating the current location was transmitted; and store the current location of the mobile terminal as the past location of the mobile terminal if it is determined that the transmission of the signal indicating the current location has been successfully completed, and not store the current location of the mobile terminal if it is determined that the transmission of the signal indicating the current location has failed.
