Abstract

From a data terminal device (3), a position notifying device (1) acquires a position request for requesting position information of a target object and identification information, with identification information for identifying the data terminal device (3) being stored in a storage section (11). In response thereto, the position notifying device (1) determines whether the currently acquired identification information is stored in the storage section (11) or not. If the identification information is stored, the position notifying device (1) generates position information of the target object, and sends the position information to the data terminal device (3).

Claims

1. A position notifying device, mounted on a moving object, for transmitting position information of a target he moving object to a remote data terminal device, comprising:

a storage section for storing identification information for identifying the data terminal device;

a reception section for receiving, from the data terminal device, a position request for requesting position information of a moving object and identification information;

an identification information determination section for, in response to the position request received by the reception section, determining whether the identification information received by the reception section has been stored in the storage section or not;

a position information generation section for, after the identification information determination section determines that the identification information has been stored in the storage section, generating position information of the moving object;

a transmission section for transmitting each piece of position information generated by the position information generation section to the data terminal device; and

an end determination section for, after the transmission section has transmitted each piece of position information, determining whether or not to end provision of position information to the data terminal device, wherein.

the position information generation section newly generates position information of the moving object, at a time interval, until the end determination section determines that provision of position information is to be ended.

2. The position notifying device according to claim 1, wherein the identification information is previously uniquely assigned for the data terminal device to perform communications.

3. The position notifying device according to claim 1, wherein the identification information is at least for a user of the position notifying device to freely determine.

5. The position notifying device according to claim 1, wherein, together with the position information, the position information generation section transmits either traveling speed information of the moving object, traveling direction information of the moving object, or a traveling route of the moving object.

4. (canceled)

6. A position notifying method for transmitting position information of a moving object to a remote data terminal device, comprising:

a storage step of storing identification information for identifying the data terminal device;

a reception step of receiving, from the data terminal device, a position request for requesting position information of a moving object and identification information;

an identification information determination step of, in response to the position request received in the reception step, determining whether the identification information received in the reception step has been stored in the storage step or not;

a position information generation step of, after the identification information determination step determines that the identification information has been stored in the storage step, generating position information of the moving object;

a transmission step of transmitting the position information generated by the position information generation step to the data terminal device; and

an end determination step of, after the position information has been transmitted in the transmission step, determining whether or not to end provision of position information to the data terminal device, wherein,

in the position information generation step, position information of the moving object is newly generated at a time interval until the end determination step determines that provision of position information is to be ended.
