[Conventional technology]

The spread of mobile terminals such as PHS phones and mobile phones is remarkable. This mobile terminal is basically used for voice information calls, but other usage methods are being actively considered. For example, Japanese Patent Laid-Open No. 9-23477, use a mobile such as a mobile phone overslept prevention method trains had are shown. This is because the same notification information as the notification information transmitted from the base station near the destination is registered in advance in the non-volatile memory of the mobile device, and the notification information received when the mobile device moves near the destination is registered. When it is confirmed that the information matches the notification information, an alarm is generated by the alarm circuit.

【0003】

Further, Japanese Patent Application Laid-Open No. 8-18501 indicates that simple navigation is performed based on the identification code of the base station. That is, a control signal (LCCH superframe) is unilaterally transmitted from the base station using the control channel, and the identification information (ID code) of the base station transmitting the control signal is included in this LCCH superframe. )It is included. On the mobile terminal side, it is detected based on the ID code or notification area information in the LCCH superframe that the mobile terminal has moved from the communication area of one base station to the communication area of another base station, and the ID code or notification area information. When is changed, the ID code sent from the base station at this time is compared with the ID code registered at the time of service (navigation) request, and when they match, a notification is sent. As a result, it is known that the base station closest to the target position, that is, the target position has been approached.

[Problems to be Solved by the Invention]

However, in the former publication technology, the notification information must be registered in advance in the mobile device, and the user must always perform the registration instruction operation of the notification information. Further, even in the latter publication technology, the ID code of the base station must be known and registered in advance before the service starts, and the base station and the ID code must be stored in advance on the mobile terminal side as a database. Will increase the memory capacity.

【0005】

By the way, when I meet with a friend, I am very worried about when and when the other person will actually come. Also, if the meeting place is not clear, it is very worrisome whether you are at the correct meeting place or heading for the correct meeting place. In such a case, considering the high spread of mobile terminals, it is desired that the mobile terminals can be used to support meetings.

【0012】

In the present invention, it is possible to support the meeting by using the mobile terminal as described above. FIG. 3 is a diagram for explaining the meeting support function. In this figure, the terminal W is a mobile terminal possessed by a waiter W'at the meeting place in the meeting area, and the terminal A is a mobile terminal possessed by a human A'who is going to the meeting place from now on. The phone mode is set to public mode. First, the terminal W transmits the identification number information (hereinafter referred to as CS-ID) of the base station of the radio zone (corresponding to the meeting area) in which the terminal W is located to the terminal A. Then, the terminal A stores the CS-ID in the RAM 13. After that, the terminal A searches for the CS-ID of the base station in the radio zone where the terminal A is located while heading to the meeting place. Now, when terminal A enters the meeting area, the received CS-ID matches the CS-ID transmitted from terminal W and stored, so terminal A, that is, human A', waits for himself. You can know that you have entered the area. As described above, according to the present invention, the human A'can go to the meeting place without error by relying on the CS-ID from the terminal W of the waiter W'. In FIG. 3, a human B'who goes to the meeting place and a terminal B possessed by the human B'are shown, and the human B'and the terminal B and the waiter W'and the terminal W also meet in the same manner. Support is possible. The area covered by one base station is about 10m to 50km in radius, although it depends on the area of the mobile communication base station, and it varies from place to place depending on the area. Only within 50m is covered in transceiver mode.

【0013】

The above-mentioned meeting support function will be described in more detail with reference to FIG. 1 using the terminal W and the terminal A. To provide meeting support, first call terminal A from terminal W, and when terminal W and terminal A are in a call state by incoming call (step S1), terminal W sends a CS-ID to terminal A (step S2). ). This CS-ID is transmitted from terminal W to terminal A by P-mail (transmission of character information using incoming subaddress information in the PHS network), and the CS-ID received by terminal W is transmitted (step). S2). Terminal A receives the transmitted CS-ID (step S2) and stores this CS-ID (step S3). After that, terminal W and terminal A end the call and disconnect each line (step S4). The CS-ID can be sent from the terminal W to the terminal A even when character information is transmitted by DTMF during a call, or can be sent as a DTMF signal by switching the mode between the terminal W and the terminal A during a call. Further, the CS-ID may be sent by P-mail after the terminal W calls the terminal A, confirms that the CS-ID will be transmitted from now on during the two-way call, disconnects the line once, and then sends the CS-ID. At this time, the terminal W can confirm with the beep of the speaker 8 that the CS-ID was successfully received by the terminal A.

【0014】

After that, the terminal W goes into the standby state (step S5). On the other hand, the terminal A starts the search (search) of the CS-ID issued from the public base station while heading to the meeting place (step S6). Then, the terminal A compares the CS-ID received in this search with the stored CS-ID (step S7), and if they match (enters the meeting area and stores the CS-ID). (When captured), the owner of the terminal A is notified of this by a notification sound, vibration of the vibrator, and a display by the display unit 3 (Fig. 2) (step S8). At the same time, the terminal A captures the CS-ID and notifies the terminal W that it has entered the meeting area by P-mail via the public base station under the operation of the owner (step S9). At this time, the owner of the terminal A can confirm by ear whether the P-mail has been successfully transmitted. Further, on the terminal W, the waiter can confirm that the terminal A has entered the meeting area by P-mail. The area-in notification to the terminal W can also be performed by a DTMF signal.

【0015】

By the way, in PHS, one base station usually covers an area with a radius of 200 to 300 m in Tokyo, where many buildings are densely packed. Therefore, in the method of supporting the meeting by relying on the CS-ID in the public mode as described above, it is possible to support until the other party approaches a distance of 200 to 300 m from the waiter. If a person on the other side enters within a distance of 200 to 300 m from the waiter, the CS-ID will remain constant and unchanged, so it will not be possible to find a meeting place by relying on the CS-ID.

【0016】

On the other hand, in the transceiver mode of PHS, the call distance is within a radius of 50 m. Therefore, if you grasp the position of the waiter to some extent in the public mode that covers a wide area, then switch the mode to the transceiver mode and search for the waiter depending on whether the call in the transceiver mode is possible or not, the other person Can support the meeting until the person approaches the waiter within 50m, and the support system can be improved.

【0017】

In such a method, the other terminal (eg, terminal A in FIG. 3) can switch to transceiver mode using means of notifying the owner that the terminal has entered the meeting area in public mode. .. Further, the terminal on the waiting side (for example, the terminal W in FIG. 3) can switch to the transceiver mode in the same manner when the notification information notifying the area-in is transmitted from the terminal on the other side (for example, the terminal A). .. At this time, the terminal on the waiting side can be set to the dual mode of public / transceiver. However, when using the transceiver mode in this way, it is necessary that both the waiting side and the other side terminals are added to the same HBS (home base station [base station]). Further, when the terminal is switched to the transceiver mode or the dual mode of the public / transceiver in this way, the operation of the CS-ID transmission means, the storage means, the search means, and the notification means as the support function in the public mode is prohibited. You can also.

【0018】

The waiting support function in the transceiver mode as described above will be described in detail with reference to FIG. 4 using the terminals W and A in FIG. In this support function, terminals W and A are first set to transceiver mode (step S11). After that, the terminal W goes into the standby state (step S12). On the other hand, in the terminal A, the wait setting (step S13) is performed by key operation. Then, the terminal A intermittently calls the terminal W at a rate of, for example, twice or less every 3 minutes, and determines whether or not there is a response from the terminal W (steps S14, S15, S16).

【0019】

On the other hand, in the terminal W in the standby state, when the terminal A approaches within about 50 m and the call becomes possible, the call from the terminal A is received (step S17). The terminal W and its owner then respond to the call (step S18). As a result, a response signal is sent to the terminal A, the terminal A has a response (step S16), and the notification means such as the notification sound, vibration, and display are operated, and the distance that oneself can talk to the terminal W is reached. In other words, it notifies that it has approached the meeting place (step S19). At the same time, the notification information is transmitted from the terminal A to the terminal W (step S20), and the terminal W is also notified that the terminal A has approached the meeting place.

【0020】

Then, if such support in the transceiver mode is performed following the support in the public mode, highly accurate meeting support becomes possible as described above. Further, in the transceiver mode, the calling side can further save the battery by performing the calling intermittently.

【0021】

On the other hand, in the support of the public mode, if the CS-ID sender sends the CS-ID, he / she may leave the meeting place until the other party reaches the meeting place, which increases the freedom. Further, the transmitting side can send the CS-ID to a plurality of parties to provide meeting support to the plurality of parties, and can grasp the position of the other party even before the other party actually appears.

【0022】

Further, according to the present invention as described above, unlike the two publication techniques described in the section of the prior art, it is not necessary to register the information from the base station in the terminal in advance, and it is necessary to register in advance and the operation status. You can use it freely when you need assistance without being restrained. Further, if the registration of information from the base station is unnecessary, the memory capacity is not increased. Furthermore, the present invention has a different object from the publication technology.

【0023】

In the present invention, the support in the transceiver mode can be separated from the support in the public mode and can be implemented by itself.

【0024】

[Effect of the invention]

As described in detail above, according to the mobile terminal of the present invention, it is possible to freely use the public mode or the transceiver mode to support the meeting when support is required without being restricted by the pre-registration / operation status. It is possible to increase the utility value of mobile terminals.
