Abstract

A mobile communication device capable of issuing a report as quickly as possible to a report destination of which telephone number or electronic mail address varies depending on the current position is provided. When identification information of the report destination is inputted, the identification information is converted to a communication address such as a telephone number or electronic mail address for the report destination corresponding with the current position of the mobile communication device such as a cellular phone by means of pattern matching and call request or transmission processing is performed. In the case of a mobile communication device with a high processing performance, the current position is located by activating the GPS prior to receiving a position communication request from the report destination, and the current position is communicated on the basis of the position communication request.

Claims

1. A mobile communication device, comprising:

storing means that stores identification information for a predetermined report destination and a communication address for each area of the report destination;

area detection means that detects the area that contains a current position; and

communication means that extracts the communication address of the report destination corresponding with the area detected by the area detection means from the storing means in response to the input of the identification information of the report destination and that communicates with the report destination by using the extracted communication address.

2. The mobile communication device according to claim 1, further comprising:

positioning means which locates the current position by means of a GPS,

wherein, upon starting communications with the report destination by using the extracted communication address, the positioning means starts to locate the current position prior to receiving by the communication means a position communication request from the report destination, and the communication means communicates the current position that is located by the positioning means to the report destination on the basis of receipt of the position communication request.

3. The mobile communication device according to claim 1, wherein the area detection means detects the area containing the current position on the basis of base station information received from a base station.

4. The mobile communication device according to claim 1, wherein the predetermined report destination is an emergency report destination including the police, fire brigade or ambulance services.

5. The mobile communication device according to claim 1, wherein the communication address is a telephone number or electronic mail address.

6. A position search method that, based on a report to a predetermined report destination from a mobile communication device that is capable of locating a current position by means of a GPS, searches for the current position of the mobile communication device from the report destination, comprising the steps of:

a communication device of the report destination acquiring mobile device information capable of identifying the processing performance of the mobile communication device, and transmitting a position communication request to the mobile communication device while communicating with the mobile communication device when it is judged that the processing performance of the mobile communication device is high on the basis of the mobile device information and transmitting a position communication request to the mobile communication device following the end of communications with the mobile communication device when it is judged that the processing performance of the mobile communication device is low; and

the mobile communication device communicating the current position that is obtained as a result of the GPS positioning to the communication device of the report destination on the basis of the receipt of the position communication request.

7. The position search method according to claim 6, wherein a mobile communication device with a high processing performance starts GPS positioning while communicating with the communication device of the report destination;

and

a mobile communication device with a low processing performance starts GPS positioning on the basis of receipt of the position communication request.

8. The position search method according to claim 6, wherein the processing performance of the mobile communication device is judged from the operating speed of a processor built in the mobile communication device.

9. The position search method according to claim 6, wherein the mobile communication device comprises storing means which stores identification information for a predetermined report destination and a communication address for each area for the report destination;

and

the mobile communication device detects the area containing the current position in response to the input of the identification information of the report destination, extracts the communication address of the report destination corresponding with the detected area from the storage means, and communicates with the communication device of the report destination by using the extracted communication address.

10. The position search method according to claim 9, wherein the communication address is a telephone number or an electronic mail address.
