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 which mutually transmits position information and displays the received position information of a partner, and a mobile communication terminal in this mobile communication system.

[0002]

2. Description of the Related Art Conventionally, the position of the mobile communication terminal itself is calculated from the base station currently used by the mobile communication terminal, and the position of the mobile communication terminal itself is displayed on the terminal of a fixed station or a mobile station. The system exists.

[0004]

Since the conventional mobile communication system is configured as described above, there has been a problem that it is not possible for the mobile communication terminals to mutually understand the position information of each other.

[0005] In the past, when meeting each other, it was necessary to confirm in advance a place where they could understand each other and then move to the meeting place. However, now that mobile communication terminals have become widespread and it is now possible to talk to the other party at any time, it is becoming more common to decide in advance only a rough place and then decide details of the meeting place while moving. However, if it is the first time or there is no characteristic landmark around the place, the place may not be well communicated to the other party.

[0006] In recent years, mobile communication terminals have spread not only as a telephone function for talking but also as very familiar mobile information terminals. However, conventional mobile communication terminals only display their own position on the mobile communication terminal. It would be very convenient if the position of the other party could be displayed on his / her own mobile communication terminal in real time.

Further, by displaying the position of the other party, it is possible to prevent malicious mischief.

Further, since the map information used for displaying the position information on the map tends to have a large amount of data, it is possible to reduce the memory capacity of the mobile communication terminal by distributing it from the base station side. Can contribute to downsizing.

The present invention has been made in order to solve the above problems, and is to configure a mobile communication system and a mobile communication terminal which allow the mobile communication terminals to mutually understand each other's position information. With the goal.
