Description

  The present invention relates to location information management of a mobile radio.

  In a general mobile radio location information management system, a mobile radio with a built-in GPS receives its own location information from a GPS satellite, and transmits the acquired location information to a base station. Then, the base station transmits the position information of the mobile wireless device to the position information management device, and the position information management device displays the position of the mobile wireless device on the map.

  However, in such a position information management system, when the mobile radio is located outside the service area of the base station, the mobile radio cannot notify the base station of the position information acquired from the GPS satellite. The management device cannot manage location information.

  As position information management methods for mobile radio devices outside the service area, those described in Patent Document 1 and Patent Document 2 have been proposed.

  Patent Document 1 discloses a method for notifying a service center of emergency information including its own location information to other vehicles equipped with the same device when an emergency situation occurs in a vehicle or the like outside the service area of an in-vehicle mobile phone. Proposes a way to send.

  Patent Document 2 also transmits emergency information to other vehicles by narrowband communication when an emergency occurs in a vehicle outside the calling range of an in-vehicle mobile phone. Proposed method to do.

A mobile station transceiver unit, further comprising a storage unit for storing location information received as another mobile radio and the first mobile radio ID, while the base station required transceiver unit is communicating with the base station In addition, when the mobile station transceiver unit receives the position information and the first mobile wireless device ID as another mobile wireless device, the storage unit stores the positional information and the first mobile wireless device ID, and the base station transceiver unit Transmits the location information, the first mobile radio ID, and the second mobile radio ID to the base station after the communication with the base station is completed .

The mobile wireless device of the present invention transmits the position information and the first mobile wireless device ID to other mobile wireless devices at regular intervals via the transmission / reception antenna. Further, when the transmission / reception unit receives the position information and the first mobile radio ID as another mobile radio, the control unit sets the second mobile radio ID unique to itself to the position information and the first mobile radio ID. The transmission / reception unit transmits the position information, the first mobile radio ID and the second mobile radio ID to the base station via the transmission / reception antenna, and the transmission / reception unit performs transmission / reception for the base station that communicates with the base station. And a mobile station transceiver unit that communicates as another mobile radio, and further includes a storage unit that stores the received location information and the first mobile radio ID as another mobile radio. If the mobile station transceiver receives the location information and the first mobile radio ID as another mobile radio while the transmitter / receiver is communicating with the base station, the storage unit receives the location information and the first mobile The wireless device ID is stored, and the transceiver for base station The position information and the first mobile wireless device ID and the second mobile wireless device ID after the communication with the base station is finished transmitting to the base station. Therefore, if your mobile radio is outside the base station area, you can relay your position information to the base station by relaying the other mobile radio if the other mobile radio is within the base station area. It is possible to manage the location information of all mobile radios in the system. Even if mobile radios in the base station area are communicating with the base station, when the mobile station transceiver receives location information from the out-of-range mobile radio, it temporarily stores them in the storage unit and communicates with the base station. Can be transmitted to the base station from the base station transceiver unit.
