DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention plots the position of a mobile phone on a display screen by using a digital wireless telephone service using a mobile phone such as a PHS, and owns the mobile phone by this display. The present invention relates to a set time search method and a set time search system in a position information search system in which a user displays current position information on a map, and a computer-readable recording medium storing a program of the method. .

[0002]

2. Description of the Related Art PHS (Personal Handy-phone System)
) Can use the digital wireless telephone service, thereby making data communication available. As an example using this data communication, PH as a terminal
It has already been provided that the user moves with S and calls this PHS to display the position of the user who owns the PHS on an electronic map. For example, if a person with a dementia disease has PHS,
By calling the HS, the current position can be displayed on the electronic map on the computer screen, and the position of the user can be immediately confirmed.

[0003] In another example, the present location is displayed on a school excursion student so that an attendant teacher can grasp the situation of the student. That is, in recent school trips such as Tokyo and Kyoto, a group of about 5 to 6 people is formed, and a daily action plan is made for each group, and for example, the city of Kyoto is followed according to this plan. To act.

[0004] When acting in each group, the teacher checks the whereabouts of the student who is acting and has one PHS for each group for emergency communication.
This is called a location information search system using a PHS, and unlike a general mobile phone, a large number of low-output wireless base stations (antennas) are installed in terms of cost, The position information is obtained by using the positions of the wireless base stations installed in a large number.

FIG. 5 shows a schematic block diagram of this position information search system. The PHS radio base station 10 has a very narrow communication area of about 10 to 500 m, so that a telephone pole, a building rooftop, a public telephone box, It is installed countlessly on the ceiling of underground malls, subway platforms, and department store ceilings. Each wireless base station 10 is connected to a network 11 such as an ISDN, and can perform data communication. Further, the PHS 17 constantly or at predetermined intervals transmits position information (position registration signal), and the personal communication service (control database 14) calls the PHS 17 via the wireless base station 10, and the As a result, the position information of the PHS 17 is received by the nearby wireless base station 10. Then, the wireless base station 10 receiving the position information from the PHS 17 sends the position information to the control database 14 of the personal communication service via the network 11, and the control database 14 stores and manages the position information of the PHS 17. .

That is, the control database 14 stores the position information of the wireless base station 10 that has received the position information from the searched PHS 17.
Is stored as position information. A PHS 17 is provided for each group, and a teacher standing by at a hotel or the like connects the search-side PHS 12 to the personal computer 13 via the data card 16, and an arbitrary PHS 17 is connected to the personal computer 13 by the above-described position information search system. When the telephone number is input and operated, a response signal from the PHS 17 is received. At this time, the position information of the PHS 17 (wireless base station 10) can be recognized by the CS-ID from the control database 14. It has become. This position information is converted into latitude and longitude information, and plotted and displayed on the electronic map on the screen of the personal computer 13 with time. The group head of the group of the PHS 17 can also be displayed.

This location information retrieval system can acquire location information by manually inputting a telephone number to each PHS 17 into the personal computer 13, and immediately confirms where a certain group is currently. You can do it.

[0008]

In such a position information retrieval system, the system is started up,
There is a problem that position information can be obtained only at predetermined time intervals such as every 0 minutes and every hour. That is, the location information of the group cannot be obtained at a preset time. For example, in a certain group, for a plan of being at “Kinkakuji” at 2:20 pm, a search for a predetermined time interval There is a problem that it is not possible to search at 2:20 pm.

[0009] Further, although the position information can be searched by manually inputting it into the personal computer 13 at that time, the operation is time-consuming, and it is possible to search only one group. However, many groups are searched at the same time. Is impossible.

[0010] That is, prior to the school excursion, a one-day plan is made in advance in the school to conduct pre-learning, and after the school excursion, whether or not the student was able to act according to the plan, and If you fail to act as planned,
In some cases, post-learning may be performed to find out what caused the inability to act. In this case, even if the location information search system searches for location information at a predetermined time interval from the departure time, the location information is different from the time of the visit place of one day of each group, and the location information at the predetermined time interval is different. In the search, there is a case where the user is in a bus, taxi, subway, or the like, and the time plan of each group and the location information search time are irrelevant, so that the location information search is not very meaningful.
