Embodiments of the present invention will be described with reference to the drawings. In this embodiment, a PHS having a high penetration rate as a simplified type telephone system is described as an example. FIG. 1 is a schematic explanatory diagram of the search system of the present invention.
FIG. 2 is a diagram illustrating the configuration of a terminal device, and FIG. 3 is a diagram illustrating the configuration of a PHS service station. The moving object search system includes a PHS terminal 10, a base station 20 that relays radio waves from the PHS terminal 10, and a PHS service station 30 that collectively manages a plurality of base stations 20 (a, b, c, d). Have. PHS
The terminal 10 is attached to a moving object and moves together with the object to be searched. The PHS terminal 10 is a transmission / reception unit 1 for PHS radio waves.
1 and a power supply unit 13. An ordinary PHS terminal has an analog / digital switch, but since this terminal is not required to have a call function, only a PHS radio wave transmitting / receiving unit 11 and a power supply unit 13 are required. Base station 20 is approximately 200
m, and each base station 20 has an ID and is registered and managed by the PHS service station 30.
The PHS service station 30 includes a PHS service control unit 31 having a control function of a normal PHS service,
A registration function unit 33 for registering D, a storage unit 35 for processing and storing and storing information from the nearest base station, an information providing unit 37 for transmitting the stored information, and a charging control unit 39 are provided.

The mechanism of the moving object search system will be described. The user inputs the ID of the terminal 10 to the PHS service station 30.
Register with a service provider that manages The terminal 10 moves with the moving object while transmitting the terminal ID. When the terminal 10 approaches the nearest base station 20a, the PHS service station 30 processes and accumulates information of the terminal ID sent from the base station 20a for each terminal ID. Here, the information processed by the PHS service station 30 obtains the address (location) information of the base station 20a from the input ID of the base station 20a. Then, the obtained address is stored in the storage unit 35 as location information. Further, the stored time is stored as time information. The service information processing / storage unit 35 processes and accumulates information for each ID of the terminal device 10 at regular time intervals.

[0008] The user can obtain desired information from the information of the PHS service station 30 stored by the user terminal 40. The user terminal 40 is an I of the terminal 10
D registration unit 41, reference unit 43 for displaying service information, storage unit 45 for storing information, charging information acquisition unit 47, PHS
A communication control unit 49 with the service station and a power supply unit 42 are provided. The user obtains the information of the terminal 10 stored in the PHS service station 30 by inputting the terminal ID of the terminal 10. That is, when the user wants to know where the moving object is now, when the user accesses the PHS service station 30 by the terminal ID of the terminal 10 attached to the moving object, the PHS service station 30 The information stored in the storage unit 35 is sent from the service information providing unit 37 to the user terminal 40. At this time, the billing information control unit 39 executes a billing process such as the number of times of use and the time of use, and sends out the billing information to the billing information acquiring unit 47 of the user terminal 40.

As described above, this moving object search system can know which base station was present at a certain time at a terminal having a terminal ID moving with the moving object. Further, by knowing the location stored at regular intervals, route information can be estimated from the travel route of the moving object and the travel distance at each time. Since the terminal 10 has no communication mechanism,
It is lightweight and can be provided economically. Also,
By providing the terminal 10 with a calling function, the presence of an unmanned moving object can be notified to the administrator by sound. Further, the billing process is executed only when the user uses the accumulated information, which makes the management easier for the user and the service provider.
