In the base station 5, the dynamic position management device 52 activates transmission to the base station radio 53 in response to a dispatch command request from the host computer 51, and transmits the dispatch command.

In the mobile station 6, when the mobile station radio 63 receives a dispatch command from the base station 5, the data processing unit 62 determines whether the dispatch command is addressed to its own station or another station, and addressed to its own station. If there is, the confirmation signal ACK is returned to the base station 5.

The dispatch command received by the mobile station 6 includes command data indicating the contents of the command and coordinate data indicating the location of the disaster, and the data processing unit 62 sends the confirmation signal A.
After returning CK, this command data is sent to the wireless data terminal device 61, and the wireless data terminal device 61 displays the content of the command.

The mobile station 6 which receives the dispatch command from the base station 5
Then, when the registration operation is performed by the wireless data terminal device 61, a dynamic registration (mobilization) signal is returned to the base station 5 to notify that the mobile station 6 has been dispatched.

In the base station 5, when the base station radio 53 receives this dynamic registration (mobilization) signal and transmits it to the dynamic position management device 52, the dynamic position management device 52 receives the vehicle identification number (vehicle ID) of the mobile station 6. ) Is confirmed and the dynamic contents are registered, and then a confirmation signal ACK is returned to the mobile station 6.

The above-mentioned movement registration (mobilization) signal includes movement contents,
After the base station 5 returns the confirmation signal ACK to the mobile station 6, which contains the vehicle ID, the current position coordinates, etc., the dynamic position management device 52 notifies the host computer 51 of the contents of the dynamic registration (mobilization). .

In addition, when the mobile station 6 that has been dispatched performs a registration operation with the wireless data terminal device 61 each time the dynamic state of the vehicle changes, the dynamic registration of the changed dynamic content is transmitted to the base station 5, and the base station 5 The confirmation signal ACK is returned to the mobile station 6.

The base station 5 notifies the host computer 51 of the dynamic contents changed every time the dynamic registration is received from the dynamic position management device 52, and the host computer 51 updates the dynamic contents and the vehicle of the mobile station 6. The current position of is updated.

[0017]

In this conventional dynamic registration method, the dynamic registration can be performed from the mobile station side at any time. Therefore, when the number of dispatched vehicles increases, the dynamic registration radio waves become congested and There has been a problem in that the reception rate is reduced on both sides of the base station, errors in received data increase, and dynamic registration cannot be performed in real time.

Also, when the mobile station cannot receive the confirmation signal ACK from the base station, the mobile station side does not register the dynamics, so that the registration operation is repeated until the dynamics registration is completed, and the operational efficiency deteriorates. There was a problem to do.

An object of the present invention is to prevent a decrease in the data reception rate and an increase in data errors on both the base station side and the mobile station side even when the number of dispatched vehicles increases, and to perform real-time dynamic registration of the mobile station. It is to provide a dynamic registration method to be realized.
