PURPOSE:To grasp the present position of a mobile station from a call termination side at the time of an emergency notice or the like by providing an input means, a position detection means and a transmission means in the mobile station and providing an emergency call judgement means and a position notice request means in a base station. CONSTITUTION:The mobile station is provided with the input means 18 for receiving the input of a user and outputting an inputted result, the position detection means 17 for detecting the position of the present station and outputting a detected result S3 and the transmission means 13, 15 and 16 for reporting the inputted result and the detected result S3 to the base station. The base station is provided with the emergency call judgement means for judging whether or not it is emergency communication and generating judgement signals and the position notice request means for letting a mobile station position detected result be reported from the mobile station to the base station based on the judgement signals. Then, when the mobile station originates an emergency signal, the base station checks whether or not it is the emergency signal and issues an instruction for letting the mobile station detect the present station position and report it to the base station in the case of the emergency signal. The base station which recognizes the position of the mobile station reports the position to a call termination side terminal. |
