Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system such as an automatic telephone system, and more particularly to a mobile communication system in which the location of a mobile station on the receiving side can be determined by the mobile station on the receiving side.

[0002]

2. Description of the Related Art Conventionally, as a system capable of knowing the current location of a mobile station of a communication partner, for example, Japanese Unexamined Patent Application Publication No.
A telephone system described in Japanese Patent Publication No. 05116 is known. In this telephone system, the exchange relation between the base station and the position name of the calling area corresponding to the base station is stored in the exchange table in advance, and when communication is performed between the mobile stations, the mobile station refers to the exchange table and moves on the called side. The location information of the caller is displayed at the station.

[0003]

In the prior art, the location information on the calling side is displayed based on the exchange relationship between the base station previously stored in the exchange table and the location name of the corresponding calling area. As a result, the location of the transmitting base station is known, but no further detailed location information is known, and it was difficult to specify a detailed address of the location of the other party.

Accordingly, an object of the present invention is to provide a mobile communication system in which the detailed current position of the transmitting side can be easily determined in view of the above-mentioned conventional problems.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a base station which is arranged for each predetermined service area and relays communication of mobile stations in the service area, and In a mobile communication system including a control station for managing a base station, the control station stores map information of a service area under the control of a subordinate base station, and the storage based on address information. Means for retrieving means and reading map information around the corresponding address, and when a call is sent from the mobile station, map information around the address information transmitted from the mobile station is read from the storage means. The current position of the mobile station on the transmitting side is displayed on the display unit of the mobile station on the receiving side by reading out the data and transmitting it to the mobile station on the receiving side.

[0006]

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the mobile communication system of the present invention. In FIG. 1, 1, 2,... N are radio base stations, and 3 is a control station.
Each base station is installed in a predetermined service area. In the example of FIG. 1, the base station 1 is installed in the service area 4 and the base station 2 is installed in the service area 5. Each base station relays communications of mobile stations within the service area. Reference numeral 6 denotes a mobile station located in the service area 4, and reference numeral 7 denotes a mobile station located in the service area 5.

The control station 3 has a plurality of base stations 2 and 3 under its control.
.. N is managed, and transmission from a plurality of base stations,
Alternatively, it controls the distribution to the base station for incoming / outgoing calls from a class (not shown) and the connection to the class. On the other hand, when each base station receives a call from a mobile station within its service area or an incoming call from a network or a mobile station of another base station, it performs call control (channel assignment, connection, etc.). . This allows communication between mobile stations in the service area, communication between mobile stations of other base stations,
Controls communication with general subscriber telephones.

Further, in the present embodiment, a home memory 8 is provided in the control station 3, and the home
Is stored in the service area where all the base stations under the control of are installed. That is, all the map information in the service areas 4, 5,... Where the base stations 1, 2,... N are installed is stored, and when the current address information is transmitted from the mobile station as described later in detail, the control station In step 3, map information around the corresponding address information is read, and the receiving side is notified of the current location of the mobile station on the calling side by the map information.

More specifically, for example, it is assumed that the mobile station 6 in the service area 4 is a calling side, the mobile station 7 in the service area 5 is a called side, and a call is made from the mobile station 6 to the mobile station 7. . At this time, in the mobile station 6, the user operates the data input unit 9 to input address information of the current location. Each mobile station is provided with a data input unit 9 and a display unit 10, and the user operates the data input unit 9 to, for example, input the address information of the current location to the address XX city XX town XX street. Enter

[0010] The input address information is transmitted to the control station 3 via the base station 1. In the control station 3, a control circuit (not shown) is provided therein. The home memory 8 is searched based on the address information transmitted by the control circuit, and map information around the corresponding address is read. It is. At this time, the control circuit reads map information in a predetermined range such as a radius of 100 m or a radius of 500 m with the current position as the center.
In the control circuit, information such as a circle indicating the current location of the address of the transmitting side is added to the read map information, and the map information is transmitted to the mobile station 7 via the base station 2.

When the mobile station 7 receives the map information, it displays the received map information on the display unit 10 to notify the user of the mobile station on the receiving side as the current address information of the mobile station on the transmitting side. In this case, as described above, information such as a circle indicating the current location is added to the map information around the current location on the transmitting side, and the current location is displayed on the display unit 10 together with the map information around the current location of the mobile station on the transmitting side. Since the mark is displayed, the receiving side can accurately know the current detailed position of the mobile station on the transmitting side. Conversely, when a call is transmitted from the mobile station 7 to the mobile station 6, by inputting the current address information from the mobile station 7, the control station 3 reads the map information around the current location from the home memory 8 and outputs the map information. Display unit 10
To be displayed.

[0012]

As described above, according to the present invention, a map of the current address of the mobile station on the transmitting side is displayed on the display unit of the mobile station on the receiving side, so that the caller's name is displayed on the receiving side. The current detailed position can be accurately known. For example, when meeting, etc., the location of the communication partner can be immediately found, which has the effect of saving time.
