Abstract

A mobile communication device and other users form a communication network along with a position search server. When a position search request from the user terminal is sent through the position search server, the mobile communication terminal determines the urgency level of that search request by referring to a telephone book having preset urgency levels. The mobile communication device automatically sends its own position data to the requesting source in response to high urgency levels such as tracing a stolen vehicle, and automatically sends its own position data or stands by for terminal user approval as required in response to low urgency level—high priority requests.

Claims

1. A mobile communication terminal device for communication with a communication network comprising:

a radio communication means for communicating by radio with the communication network;

a position data memory for storing position data indicating a current position;

an input means for a user to enter instructions;

a determination means for deciding an urgency level of a position search request received by the radio communication means from the communication network, and sending the position data to a station making the position search request when the determination means determines the urgency level is high and,

a control means to send the position data to the station upon deciding that the urgency level is low and the user entered an approval instruction by the input means.

2. A mobile communication terminal device as in claim 1, wherein:

the radio communication means receives urgency level information indicating the urgency level of the position search request; and

the control means determines the urgency level of the position search request based on the urgency information.

3. A mobile communication terminal device as in claim 1, further comprising:

a telephone book memory for storing preset telephone numbers of other stations and priority level information related to the preset telephone numbers; and

a requesting station determination means for determining whether telephone number of the requesting station determined to have a low urgency level is contained in the telephone book memory,

wherein the control means sends the position data to the requesting station, when determined by the determination means that the telephone book memory does not contain the telephone number but the user enters an approval instruction by the input means.

4. A mobile communication terminal device as in claim 1, further comprising:

a telephone book memory for storing preset telephone numbers of stations; and

a requesting station determination means for determining whether a telephone number of the requesting station determined to have the low urgency level is contained in the telephone book memory,

wherein the control means sends the position data to the requesting station when the determination means determines the telephone number is contained in the telephone book memory, and

wherein the control means sends the position data to the requesting station, when the determination means determines that the telephone number is not contained in the telephone book memory but the user enters an approval instruction by the input means.

5. A mobile communication terminal device as in claim 1, further comprising:

a telephone book memory for storing preset telephone numbers of other stations and priority level information related to the preset telephone numbers; and

a requesting station determination means for determining whether the telephone number of the requesting station determined to have a low the urgency level is contained in the telephone book memory,

wherein the control means sends the position data to the requesting station, when determined by the determination means that the telephone book memory contains the telephone number and that information with a high priority level is contained in the telephone book memory.

6. A mobile communication terminal device as in claim 1, further comprising:

a telephone book memory for storing preset telephone numbers of other stations and priority level information related to the preset telephone numbers; and

a requesting station determination means for determining whether the telephone number of the requesting station determined to have the low urgency level is contained in the telephone book memory,

wherein the control means sends the position data to the requesting station, when the user enters an approval instruction by the input means under a condition that the telephone book memory contains a low priority level of the telephone number of the requesting station.

7. A method of communication with a communication network comprising steps of:

detecting an urgency level of a position search request received from a requesting station through the communication network;

sending a position data to the requesting station that issued the position search request, when it is determined in the detecting step that the urgency level is high; and

sending the position data to the requesting station that issued the position search request, when a user enters an approval instruction although the urgency level is low.

8. A mobile communication terminal device for communicating with a communication network comprising:

a position data memory for storing position data showing a current position;

an input means for a user to enter instructions;

a determination means for determining a requesting station of a position search request received through the communication network; and

a control means for sending the position data to the requesting station when it is determined by the determination means to be a first search requesting station, for sending the position data to the requesting station when the user enters an approval instruction by the input means even if it is determined to be a second search requesting station different from the first search requesting station.

9. A mobile communication terminal device as in claim 8 further comprising:

an input means for a user to enter instructions;

a telephone book memory for storing preset telephone numbers of other stations and priority level information relating to the preset telephone numbers; and

a requesting station determination means for determining whether a telephone number of the requesting station determined to be the second request station is contained in the telephone book memory,

wherein the control means sends the position data to the requesting station without the user entering an approval instruction by the input means, when the determination means determines that both the telephone number and information with a high priority level is included in the telephone book memory.

10. A mobile communication terminal device as in claim 9, wherein the control means sends the position data to the requesting station when the user enters an approval instruction by the input means, even if when the determination means determines that the telephone number is included and the priority level is low.

11. A mobile communication terminal device as in claim 9, wherein the control means refuses to send the position data to the requesting station when the determination means determines the telephone number is included but the priority level in the telephone memory book is low.
