The mobile terminal 10 and the base station 3 in the above configuration
The operation of 0 will be described with reference to FIG. 4, FIG. 5, and FIG. Here, in FIG. 4, it is assumed that the mobile terminals 1 and 2 have the same configuration as the mobile terminal 10, and the base station 3 has the same configuration as the base station 30. Here, the table described in the portion of the base station 3 in FIG. 6 shows the terminal information table, and “name” indicates the terminal name, “exist” indicates whether or not the terminal exists in the service area, and “ Indicates a group partner. Therefore, the left column of the table described in the base station 3 indicates the terminal number, the middle column indicates YES or NO, and the right column indicates the group partner terminal number. Become.

First, in the portable terminal 1 or 2, the base station 3
Make a group registration request to. That is, the mobile terminal 1
Alternatively, in step 2, a group registration request signal including the terminal number of the group partner is transmitted via the key input unit 14 (see S0 in FIG. 6). Specifically, enter a special number for group registration or, if a key for group registration is provided separately, press that key to set the group registration request signal transmission mode, followed by the terminal number of the group partner Enter When the mobile terminal 2 is to be the group partner in the mobile terminal 1, the terminal number 2 is input as the terminal number of the group partner. Here, display indicating that the mode is the group registration request signal transmission mode and display of the terminal number of the group partner are performed on the display unit 15. Then, by pressing a predetermined transmission button in the key input unit 14,
A group registration request signal is transmitted to base station 3.

Next, upon receiving this group registration request signal, the base station 3 registers in the terminal information table provided in the group registration section 361 of the storage section 36.
That is, as shown in FIG. 3, the mobile terminal name including the terminal name of the mobile terminal that transmitted the group registration request signal is registered, and the terminal name of the group partner is registered. Also,
The base station 3 periodically transmits and receives control signals to check reception sensitivity via the mobile terminals 1 and 2 and the like, the antenna 11 and the transmission / reception circuit 12, and checks terminals within the service area. , receiver sensitivity has exceeded the threshold value is good (S1), for those not exposed to the registration (S2), together with the terminal name of the portable terminal name and group opponent to whether existing in a service area "YE
S "is registered in the terminal information table (S3).

For example, when a group registration request signal is transmitted from the portable terminal 1 with the portable terminals 1 and 2 as a group, the reception sensitivity of the portable terminals 1 and 2 is checked, and the portable terminal 1 is added to the terminal name. The mobile terminal 2 is registered, and YES is registered for each of the mobile terminals 1 and 2, and the mobile terminal 1 is registered for the mobile terminal 1 and the mobile terminal 1 is registered for the mobile terminal 2 as a group partner.

Next, consider a case where the portable terminal 2 has been out of the service area of the base station 3. In this case, since the reception sensitivity is equal to or less than the threshold in the check, the mobile terminal 2 is changed to “NO” to determine whether or not it is in the service area of the terminal information table (S4), and the group partner is checked. Then, if there is a group partner, the group partner movement information is transmitted to the group partner (S6). Since the mobile terminal 2 is registered as the group partner, the mobile terminal 2 transmits to the mobile terminal 1 that the mobile terminal 2 as the group partner has moved. In the portable terminal 1 that has received this transmission, a notification sound is generated via the speaker 17 or a message indicating that the portable terminal 2 has moved is displayed on the display unit, such as “terminal 2 moved”.

Thus, the user of the portable terminal 1 can know that the portable terminal 2 has moved. Also, mobile information can be provided only by the mobile terminal and one base station without centrally managing the location information of the mobile terminal by the central office or the exchange. As a specific application example of the mobile phone system in this embodiment, a plurality of mobile terminals are owned by a family or a group in an amusement park or the like,
It is possible to monitor each other's movement by having the family and an elderly person who has a wandering habit.

Note that, upon receiving a group registration request signal from a mobile terminal and checking the reception sensitivities of the mobile terminal that transmitted the group registration request signal and the mobile terminals of the group of mobile terminals, first, all mobile terminals were checked. Normally, the reception sensitivity exceeds the threshold value and is in the service area, but if the mobile terminal already exits the service area at that time, whether or not it is in the service area of the terminal information table Is registered as “NO”. When a mobile terminal that is not present in the service area and registered as “NO” enters the service area, this is changed to “YES”. Further, in the above description, the base station 3 automatically transmits the group partner movement information to the mobile terminal 1. However, the base station 3 sends the movement information in response to the transmission of the movement information request signal from the mobile terminal 1. You may do so.

Next, a second embodiment will be described. Second
In the mobile phone system of the embodiment, the center is connected to a mobile terminal and a base station having substantially the same configuration as in the first embodiment and further to a wired network connected to the base station, and controls the entire mobile phone system. 90 (see FIG. 7).
Here, the mobile terminal of the present embodiment has a function of receiving and outputting the group partner movement information transmitted from the center 90 via the base station, in addition to the function of the mobile terminal of the first embodiment. Further, in addition to the function of the mobile terminal in the first embodiment, the base station of the present embodiment transmits the content registered in the terminal information table to the center upon receiving a group registration request signal from the mobile terminal, When the mobile terminal leaves the service area, the mobile terminal transmits the terminal movement information to the center. The base station of this embodiment has the same terminal information table as that of the first embodiment.
For example, the base stations 6 and 8 respectively correspond to FIG.
It has a terminal information table as shown in FIG.

The center 90 includes a transmitting / receiving unit 91
, A control unit 92, and a storage unit 93. Here, the transmission / reception circuit 91 performs communication with the base station, and the control unit 92 controls the operation of each unit of the center 90. The storage unit 93 includes a group registration unit 931 as shown in FIG. The group registration unit 931 has a table as shown in FIG. 8. The table includes a terminal name of each mobile terminal, information on a service area where the terminal is located, information on a group partner with respect to the terminal, and the like. Is stored.

Here, the operations of the portable terminal having the above configuration, the base station, and the center will be described with reference to FIGS. The description of the same operation as in the first embodiment is omitted. In the description of the operation of this embodiment, FIG.
As shown in FIG. 9 , a description will be given using a mobile telephone system in which base stations 6 to 8 are connected to a public network and a center 9 is connected. It is assumed that the mobile terminals 4 and 5 are initially in the service area of the base station 6. Here, the base stations 6 to 8 are base stations having the configuration according to the second embodiment described above, and the mobile terminals 4 and 5 are also mobile terminals having the configuration according to the second embodiment described above. It is. The center 9 has the same configuration as the center 90.

Here, the table described in the base station 6 in FIG. 12 shows the terminal information table as in the case of FIG. 6, and the left column of the table described in the base stations 6 and 8 Indicates the terminal number, the middle column indicates YES or NO, and the right column indicates the terminal number of the group partner. The table in the center of FIG. 12 shows the terminal information table (see FIG. 8) provided in the center, where “name” indicates the terminal name,
“Sa” indicates the number of the existing service area, and “g” indicates the group partner. Therefore, the left column of the table described in the center indicates the terminal number, and the middle column indicates the number of the existing service area. And the right column indicates the terminal number of the group partner.

First, as in the first embodiment, the portable terminal issues a group registration request to the base station. Here, it is assumed that the mobile terminal 4 issues a group registration request for grouping the mobile terminals 4 and 5 (FIG. 12).
S0). Then, the group registration request signal is received by the base station 6, and the base station 6
1 is registered in the terminal information table provided in the terminal 1. That is, the reception sensitivity of the mobile terminals 4 and 5 is checked, and FIG.
Registration is performed as shown in FIG. 2 (see S1 to S3 in FIG. 11). Therefore, when the above-described group registration request is made from the portable terminal 4, the presence or absence of the portable terminal 4 is determined to be YES in the terminal information table of the base station 6 as shown in FIG. The other party is registered as the mobile terminal 5, and the presence or absence of the mobile terminal 5 is YES.
Thus, the group partner is registered with the mobile terminal 4.

Then, the base station 6 transmits the contents registered in the terminal information table to the center 9 as terminal movement information (see S7 in FIGS. 11 and 12). That is, the terminal information table of the center 9 includes, as shown in FIG.
For the mobile terminal 4, the service area is the base station 6 and the other party in the group is the mobile terminal 5.
The service area is the base station 6 and the other party of the group is registered with the mobile terminal 4.

Next, it is assumed that the portable terminal 5 moves and moves from the service area of the base station 6 to the service area of the base station 8. Then, the base station 6 changes the terminal information table (S4 in FIG. 11), and if there is a group partner, transmits the information to the group partner (FIG. 11).
S5, S6). That is, since the mobile terminal 5 has left the service area of the base station 6, the presence or absence of the mobile terminal 5 is NO (see FIG. 10A), and the mobile terminal 5 has left the service area of the base station 6. Is transmitted to the portable terminal 4 (S6 in FIGS. 11 and 12). Then, the portable terminal 4 receiving this outputs the information by a notification sound or display, and it can be seen that the portable terminal 5 has left the service area of the base station 6 in the portable terminal 4. Also, base station 6
Similarly transmits to the center 9 that the mobile terminal 5 has left the service area of the base station 6 (FIG. 11, FIG. 12 S
8) At the center 9 receiving this, the information on the service area of the portable terminal 5 is canceled.

When the mobile terminal 5 moves to the service area of the base station 8, the reception sensitivity of the mobile terminal 5 in the base station 8 becomes better. Register in the terminal information table (Fig. 1
1 S1 to S3), specifically, in the terminal information table of the base station 8, the mobile terminal 5 becomes YES. Further, the base station 8 transmits to the center 9 that the mobile terminal 5 has entered the service area of the base station 8 (FIG. 11, FIG. 12 S
7). Then, since the center 9 knows that the mobile terminal 5 has entered the service area of the base station 8, the center 9
Is a base station 8.

Then, the service area of the portable terminal 5 is changed, and the center 9 changes the service area of the portable terminal 5.
The mobile terminal 5 searches for whether there is a partner in the group, and if so, notifies the partner in the group that the mobile terminal 5 has moved to its own service area. That is, since the mobile terminal 5 includes the mobile terminal 4 as a partner of the group, the mobile terminal 4 is notified that the mobile terminal 5 has moved to the service area of the base station 8. More specifically, since the service area where the mobile terminal 4 is located is the service area of the base station 6, the group partner movement information is temporarily transmitted to the base station 6 (S9). The group partner movement information includes destination information (in this case, the mobile terminal 4), information of the mobile terminal that has moved (in this case, the mobile terminal 5), and information of the service area that has moved (this In this case, the base station 8).

When receiving the group partner movement information, the base station 6 looks at the transmission destination information and instructs the mobile terminal 4 to "move the mobile terminal 5 to the service area of the base station 8".
Then, the group partner movement information to the effect is transmitted (S10). Then, the portable terminal 4 outputs an indication that "the portable terminal 5 has moved to the service area of the base station 8". Therefore,
When the owner of the mobile terminal 4 wants to find the owner of the mobile terminal 5, the service area of the base station 8 may be searched.

Thus, when the mobile terminal of the group partner moves, it is possible to know the destination of the movement, and it is very useful when the lost person in the amusement park or the location of the old man who has a wandering habit is unknown. It is effective.

The center 9 may not only transmit the information on the moved portable terminal to the group partner but also transmit the position information of the group terminal to the moved portable terminal. That is, in the above example, the mobile terminal 5
When the service area where is located is changed, the information of the mobile terminal 4 is transmitted to the mobile terminal 5 via the base station 8 (S11, S12). In other words, by transmitting to the mobile terminal 5 that the mobile terminal 4 is in the service area of the base station 6, the mobile terminal 5 only has to head toward the base station 6 where the mobile terminal 4 is located.

Note that, in the above example, the base station 8
When the mobile terminal has moved, it can be detected that the mobile terminal 5 has entered its own service area, but since the group partner of the mobile terminal 5 is not known, the information about the group partner is requested from the center 9. (S13). That is, the base station 8 requests the information on the group partner from the center 9 and obtains a reply about the group partner from the center 9 to register the group partner with respect to the mobile terminal 5 as the mobile terminal 4 (FIG. 10B). reference). By doing so, for example, if the mobile terminals 4 and 5 move together to the service area of the base station 8 and then the mobile terminal 5 moves to another service area, the base station 8 When transmitting to the group partner that the mobile terminal 5 has left, information on the group partner that is the transmission destination can be secured.

In the second embodiment, when the portable terminal 5 moves out of the service area of the base station 6, the fact that the portable terminal 5 has been separated is transmitted to the portable terminal 4 (FIG. 12, S6). ), Since the destination is finally known from the information from the center 9, the processing may be omitted. Further, in the second embodiment, when the mobile terminal moves, the destination is automatically transmitted to the mobile terminal of the group partner. However, the mobile terminal receives a request for information of the group partner from the base station. Only when this occurs, the information may be transmitted from the center 9. By doing so, useless transmission can be prevented.

In the first and second embodiments,
Although a case has been described where two mobile terminals are grouped, three or more mobile terminals may be grouped. In this case, a plurality of mobile terminal names will be registered for the other party of the group in the terminal information table of the base station and the center, and when a certain mobile terminal moves,
The group partner movement information will be sent to all other group partner mobile terminals.

Further, in each of the above embodiments, each mobile terminal has been described as having the configuration shown in FIG. 1. However, in a plurality of mobile terminals, one is a parent terminal and the other is a child terminal. The child terminal has a simple configuration of a transmission / reception circuit, a control unit, a storage unit, etc., and when the child terminal moves, the parent terminal is notified that the child terminal has left the service area or the destination of the child terminal.
