できる。Referring to FIG. 1 showing an embodiment of the present invention, a mobile telephone exchange device 1 is connected to a mobile unit 4 via a mobile radio base station 3.
And a communication connection with the mobile unit 4 'via the mobile radio base station 3'. The mobile telephone exchange device 1 stores map information of an area that can be covered wirelessly by a map information storage device 2.
I remember. The stored map information can be categorized for each mobile radio base station 3, 3 'and can be read arbitrarily, and the latest map information corresponding to a section change such as a road can be updated. The mobile units 4 and 4 'have mobile radio terminal units 5 and 5' for performing communication control with the mobile telephone exchange 1 and map information storage units 6 and 6 'and display units 7 and 4, respectively.
7 '. The mobile unit 4 sends out a call signal when it needs map information or when talking with a normal telephone subscriber 8. This call signal is received by the mobile radio base station 3 and transferred to the mobile telephone exchange 1. The mobile telephone switching device 1 identifies the geographical position of the mobile radio base station 3 that has received the call signal, and reads out map information corresponding to the installation position from the map information storage device 2. Subsequently, the mobile telephone exchange 1 broadcasts the map information via the mobile radio base station 3 using a radio channel corresponding to the mobile 4. The mobile unit 4 receives the broadcasted map information using the mobile wireless terminal device 5 and stores the received map information in the map information storage device 6 in the mobile unit 4. The stored map information can be arbitrarily referred to in the mobile unit 4.

る。Further, when the mobile unit 4 deviates from the wireless service area of the mobile radio base station 3 which has been performing the communication operation in advance and moves to the wireless service area of the mobile radio base station 3 ′,
Here, the same mobile unit 4 will be referred to as a mobile unit 4 ′, but the mobile telephone exchange 1 uses the radio channel of the mobile radio base station 3 based on the electric field strength information reported from the mobile radio base station 3. Is stopped, and it is determined to use the wireless channel of the mobile base station 3 '. When this determination is made and the mobile radio base station 3 'establishes communication connection with the mobile 4', the mobile telephone exchange 1 stores map information corresponding to the installation position of the mobile radio base station 3 'in the map information storage device. 2 and broadcast via the mobile radio base station 3 '.
The mobile unit 4 'updates the previously stored map information with the broadcasted map information and stores it again. Thereby, it is possible to refer to the optimal map information according to the moving route of the moving object.
