Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wireless telephone switching system in which a terminal device, typified by a car telephone, moves, and is particularly intended to display location information of the terminal device.

<Background> Conventionally, in wireless telephone switching systems, there has been a system in which the location of a moving terminal device is identified and an appropriate wireless channel is assigned to the terminal device based on the location information. However, no attempt was made to display its location.

<Summary of the Invention> This invention adds a device (e.g., printer) that displays location information to the conventional wireless telephone exchange system with a location identification function, and further converts the location information into additional information (e.g., road name, place name). The object of the present invention is to provide a method for displaying location information and additional information in accordance with terminal device identification information.

According to this invention, in the wireless telephone switching system,
A display device and a translation device that converts the location information into additional information are added to the method that can identify the location information of a moving terminal device, and it displays the location of the mobile terminal device and also displays road names, place names, and nearby information. Display additional information such as police station.

This translation device uses location information to translate road names, place names,
Contains translation data that converts to information on nearby fire stations, police stations, etc.

Next, embodiments of the invention will be described with reference to the drawings.

<Example> This invention will be explained with reference to the drawings showing examples of the invention. An example of this is when a driver of a car equipped with a terminal device witnesses an incident while driving on the road, dials "110" from the terminal device, and reports the incident to a center operator.

The movement range of the car is multiple service areas 0
Divided into 1 and 02, each service area 01 and 02
Transmitter/receiver 11, 1 covering respective areas
2 is provided.

When the driver makes a call, the terminal device in the automobile 50 sends out a calling signal 21 to which terminal device identification information is added through the optimum wireless channel depending on the radio wave strength from the transceivers 11, 12, . . . of the wireless base station. The terminal device then sends out a dial signal 22 of "110" through the optimum radio channel, and reports to the car telephone exchange 31 via the transceiver 11 that it is an emergency call.

The switch 31 uses the control unit 33 to analyze the dial to indicate that it is an emergency call, and sends the trunk 3 to the center 41.
2. Select line 42 and make a call to operator console 43 of center 41. On the other hand, the exchange 31 relays the terminal device identification information and the corresponding service area information (location information) 46 to the translation control device 45 in the center 41 through the data line 44.

The translation control device 45 translates the received service area information 46 from pre-existing translation data into additional information. Additional information includes place names, road names 03 and 04, the nearest police station 05 or fire department, and their contact telephone numbers. This additional information is immediately output to the printer 47.

The operator of the center 41 communicates with the driver of the car 50 via the transmitter/receiver 11, switchboard 31, and reception desk 43, and uses the information output from the printer 47 to obtain information about the surrounding situation at the location where the incident, accident, fire, etc. has occurred, as well as the command destination. You can even know. Furthermore, in this embodiment, terminal device identification information (in this embodiment, a telephone number) is also output, so that it can be used to respond to repeated calls from the operator.

<Effects> As explained above, this invention converts the location information from the switchboard into additional information such as place name, road name, nearby police station, fire department, etc., and informs the operator of the information, thereby giving prompt and accurate instructions. There are some effects that can be achieved.

Claims (1)

[Claims] 1. In a wireless telephone switching system that uses control signals with terminal device identification information added between a wireless base station and a terminal device, the identification information of the terminal device involved in the call as well as the location of the moving terminal device are transmitted. The terminal device is identified, the information is sent to the center, and the center's control device displays the identification information of the terminal device, translates the location information, and displays the location information and related additional information. A mobile terminal device location display method.
