A mobile terminal comprising: a receiver adapted for receiving 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; a transmitter adapted for transmitting signals to the information service providing communication apparatus; a locator adapted for repeating identifying a location of the mobile terminal; a linear movement distance calculator adapted for calculating a linear movement distance of the mobile terminal between a past location of the mobile terminal and a current location of the mobile terminal; a comparative determiner adapted for determining whether or not the linear movement distance calculated by the linear movement distance calculator is greater than a threshold; a current location signal transmission regulator adapted for regulating the transmitter, so that the transmitter transmits a signal indicating the current location of the mobile terminal identified by the locator if the comparative determiner has determined that the linear movement distance is greater than the threshold, the current location signal transmission regulator adapted for regulating the transmitter so that the transmitter does not transmit the signal indicating the current location if the comparative determiner has determined that the linear movement distance is less than the threshold; a memory adapted for storing the past location of the mobile terminal; the mobile terminal being characterized by further comprising: a transmission-success-failure determiner adapted for determining whether or not transmission of the signal indicating the current location has been successfully completed by the transmitter; and a past location recorder adapted for recording in the memory the current location of the mobile terminal identified by the locator as the past location of the mobile terminal if the transmission-success-failure determiner determines that the transmission of the signal indicating the current location has been successfully completed, wherein the past location recorder is adapted for not recording in the memory the current location of the mobile terminal identified by the locator if the transmission-success-failure determiner determines that the transmission of the signal indicating the current location has failed. a receiver adapted for receiving 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;
