Mobile communication terminals 81, 82, 83 and 8
Reference numerals 4, 85, and 86 each have an individual mobile communication terminal identification number, and are associated with one of the plurality of mobile exchanges 11, 21 and the like. Recorded in the exchange. For example, FIG.
Assuming that the mobile communication terminal 81 belongs to the mobile exchange 11, the subscriber data of the mobile communication terminal 81 is stored in the subscriber data memory 121 of the memory device 41 of the mobile exchange 11, and the location information is It is stored in the mobile location information memory 101 of the memory device 41 of the mobile switching center 11. In FIG. 1, a mobile communication terminal 81 exists in a wireless zone 61 of a base station 71 of a radio network controller 91 of a mobile switching center 11. This wireless zone 61 is used as position information,
The information is stored in the mobile location information memory 101 together with the communication terminal identification number of the mobile communication terminal 81. At the same time, the network / subscriber data management device 51 is connected via the data link 9.
The location information and the communication terminal identification number are stored in the mobile communication terminal location information memory 140. It is also assumed that the mobile communication terminal 81 has moved from the wireless zone 61 to the wireless zone 64. The location information of the mobile communication terminal 81 to which the mobile terminal has moved needs to be the wireless zone 64 of the base station 74 of the wireless network controller 92 of the mobile switching center 12.
For this reason, the location information is transferred via the data link 9 to the mobile switchboard 11 that originally accommodated the mobile communication terminal 81, and the mobile location information memory 101 is rewritten. The position information is also transferred to 51 and the mobile communication terminal position information memory 140 is rewritten. As a result, the mobile communication terminal 81 is connected to the radio zone 6 of the base station 74 of the radio network controller 92 of the mobile switching center 12.
4 are recognized.

Next, an example of a method of performing a group for realizing the present invention by a subscriber contract will be described. Here, it is assumed that each subscriber of the mobile communication terminals 81 and 84 and the fixed terminal 1 forms one group. When a new group is created, a subscriber who intends to form the group applies for an application for creating a group to a network administrator who manages the fixed networks 3 and 4, the mobile switching network 5 and the common channel signaling networks 6 and 7. And make a subscriber contract. The network manager who has received the application operates the operation terminal 52 connected to the network / subscriber data management device 51, and stores the group identification number and the mobile communication terminal and fixed terminal that join the group in the group configuration memory 141. Stores the type and telephone number. FIG. 3 shows an example of a data format stored in the group configuration memory 141. In the example shown in FIG. 3, the group configuration memory 141 is provided for each group, and includes a group code 201 for identifying the group in the entire communication network, a group configuration number 202 indicating the number of groups, and a group responsibility. Data (terminal phone number)
203 and data (terminal telephone numbers) 204 of group members excluding the responsible person are recorded. In addition, for a group, whether the group calling method according to the present invention is closed and used only for members of the group, or the calling code of the group is disclosed to members other than the members of the group, and the group calling is performed from all terminals. A flag 1 (group call restriction flag) is provided in the group code 201 in order to determine whether the group code can be performed. For example, if the first digit of the group code is "0", only members belonging to the same group can call.
If "1" is set beforehand at the time of contract, it can be identified from terminals other than the group members, so that it can be identified at the time of an incoming call. Further, a flag 2 (group joining method identification flag) is provided at the head of the group manager terminal telephone number 203, and it can be set whether or not to inquire of the manager about joining the group. For example, if the flag 2 is "0", the responsible person is inquired of the group joining, and if the flag 2 is "1", it is set so that the network administrator judges whether or not the joining is possible. Further, as the flag 3 (terminal type flag), a fixed terminal or a mobile communication terminal is set.

The data stored in the group configuration memory 141 is transferred from the network / subscriber data management device 51 to the exchange to which each terminal belongs via the data link 9. For example, in the case of the mobile communication terminal 81, the mobile switch 1 is transmitted from the network / subscriber data management device 51 via the data link 9.
1 and transferred to the group attribute memory 1 of the memory device 41.
11 is stored. FIG. 4 shows a group attribute memory 11.
1 and 112 show configuration examples. In addition, it is assumed that a group attribute memory 113 having the same configuration as the group attribute memory 111 is also stored in the fixed network exchange in which the fixed terminal 1 is accommodated, as shown in FIG. In the example shown in FIG. 4, the group attribute memory 111 stores the subscriber (user).
Area coordinates 301 indicating the area coordinates of the communication terminal described later, the number of groups 302 indicating the number of groups to which the user of the terminal has subscribed, and the user recognizing (registering)
User recognition group number 30 indicating the group number to perform
3. Group code 30 indicating the group code on the communication network side corresponding to the group number 303 recognized by the user
And 4, an incoming call mode 305 for setting ON / OFF of incoming calls for each group. In the incoming call mode 305, when a user subscribes to a plurality of groups, a group to receive a group call is set for each terminal. For example, when the mobile communication terminal 81 has subscribed to three groups, the incoming call is set to ON for a group that receives a group call, and the incoming call is set to OFF for a group that cannot be called. Also,
The group number 303, the group code 304, and the incoming call mode 305 exist as many as the number of groups 302 to which the user has subscribed. Group number 303 recognized by the user
Can be arbitrarily registered by the subscriber at the time of group configuration, and is input from the operation terminal 52 of the network / subscriber management device 51 and transferred together with other data. Here, when the group member is a fixed terminal, the telephone number / region coordinate conversion device 14 of the network / subscriber data management device 51 is used.
2, the location of the fixed terminal is quantified.

FIG. 5 shows a conceptual diagram when converting a telephone number into local coordinates. A range to which the calling method according to the present invention is applied is divided into a grid pattern at equal intervals, and a square surrounded by a horizontal line and a vertical line with the accommodation exchange as a starting point (1, 1) is referred to as one regional coordinate area. In FIG.
Assuming that the area where the fixed terminal exists is the third area in the horizontal direction and the third area in the vertical direction, the relative area coordinates of the fixed terminal 1 are (3, 3). The database 144 stores the relative value area coordinates of the fixed terminal and the base station with respect to the accommodation exchange and the coordinates of the absolute position of the accommodation exchange. In order to convert the telephone number into the local coordinate of the absolute position, the telephone number / local coordinate conversion device 142 stores the local coordinate of the absolute position of the accommodation exchange and the local coordinate of the relative position corresponding to the telephone number of the terminal in a database. 144. As shown in FIG. 6A, the telephone number / region coordinate conversion device 142 obtains the absolute position coordinates of the accommodation exchange using the station number as a key, and further obtains the corresponding relative position from the terminal telephone number. The absolute position coordinates of the terminal are calculated and obtained from the coordinates of. The obtained absolute position coordinates are stored as area coordinates in the group attribute memory 113 of the exchange of the fixed network in which the fixed terminal 1 is accommodated via the common channel signal network 6.

In the case of a mobile communication terminal, when a location is registered within a certain radio zone, the position of a base station forming the radio zone is replaced with local coordinates. For example, in FIG. 5, the mobile communication terminal 81 is inside the wireless zone 61, and the mobile switch 1 is connected via the base station 71.
When the location registration information is stored in the first mobile information memory 101, the location information is transferred to the network / subscriber data management device 51 via the data link 9, and the mobile communication terminal location information memory 140 is rewritten. The position information is converted into local coordinates by the position information / region coordinate conversion device 143 using the position information. The location information / area coordinate conversion device 143 converts the location information into the absolute location area coordinates based on the absolute position area coordinates of the exchange, and the relative location area coordinates corresponding to the base station where the terminal is located. With reference to the database 144. The database 144 stores, for example, the area coordinates of the relative position corresponding to the base station as shown in FIG. As shown in FIG. 5, since the local coordinates of the position information of the base station 71 are (7, 4), by referring to this, the local coordinates of the mobile communication terminal 81 are set to (7, 4). I do. As shown in FIG. 6 (2), the position information / region coordinate conversion device 143 obtains the absolute position coordinates of the accommodation exchange using the station number as a key, and further obtains the corresponding relative position from the terminal position information. The absolute position coordinates of the terminal are calculated and obtained from the coordinates of. The obtained absolute position coordinates are set as area coordinates and stored in the group attribute memory 111 of the mobile switching center 11 via the data link 9.

Next, an example of a method of registering a group for realizing the calling method according to the present invention will be described with reference to FIG. By dialing a telephone number managed in a predetermined number format from a communication terminal (here, the mobile communication terminal 81), the mobile terminal is connected to the accommodating exchange (here, the mobile exchange 11). The central office 11 is connected to the network / subscriber data management device 51 via the common line signaling network 6 or the data link 9. In this example, the mobile communication terminal 8 in the communication state
1 and the network / subscriber data management device 51 are registered (contracted) by the mobile communication terminal 81 pressing its number key according to the guidance of the network / subscriber data management device 51.
And how to do it. Here, the mobile communication terminal 81
Is the group manager, the mobile communication terminals 82 and 83 and the fixed terminal 1 are other member constituent terminals, and the group is 4
An example in which a person is used will be described.

In FIG. 8, first, for a group to be accessed from now on, newly created “0”, erased “1”,
The user inputs which operation of group member change “2” is to be performed (step 601). When "1" is pressed, a predetermined deletion process is performed to delete a group or a group member. When "2" is pressed, the group member is changed by a predetermined change process as a change of the group member. Here, it is assumed that “0” is input as a new creation. At this time, an area of the buffer memory 147 for temporarily storing the contents as shown in FIG. 4 is secured.

Next, the number of persons constituting the group ("4" in the example) is received and stored in the group number 202 of the buffer memory 147 (step 602).
Next, the input of the telephone number of the group manager is accepted (step 603). In order to check whether the telephone number input in step 603 is a telephone number registered properly in the fixed networks 3 and 4 and the mobile switching network 5,
The data is transferred from the network / subscriber data management device 51 to the exchange (mobile exchange 11) that accommodates the telephone number of the group manager, and is registered in the subscriber memory 121 of the memory device 41 of the mobile exchange 11. Mobile communication terminal 81
And the result is transferred to the network / subscriber data management device 51 (step 604). Step 60
If 4 is NG, the process returns to step 603. If step 604 is OK, the input telephone number is stored in the data 203 of the group manager in the buffer memory 147, and one is added to the input number of the telephone number (step 604-).
1). Next, the input of the telephone numbers of the members constituting another group is accepted (step 605). Next, as in step 604, the telephone number input in step 605 is collated (step 606). If step 606 is NG, the process returns to step 605. If step 606 is OK, the input telephone number is stored in the group member data 204 of the buffer memory 147, and the number of input telephone numbers is added by 1 (step 606-1). Next, if the number of input telephone numbers that have been verified as OK in steps 603 and 606 is smaller than the number stored in the group member 202 in the buffer memory 147, the processing in steps 605 and 606 is performed, and the numbers are equal. This is repeated until it becomes (step 607).

Next, an input of a number recognized by the user as a group is received (step 608). In order to confirm that this number is not the number already used by the group members, the data 203 of the group manager and the group member data 20 in the buffer memory 147 are checked.
Exchange (mobile exchange 1
1 and 12 and the exchanges of the fixed network 3) are transferred via the common line signaling network 6 and the data link 9 to the group numbers input in step 608, and are recognized by the users of the group attribute memories 111, 112 and 113 of each exchange. A comparison result with the group number 303 to be performed is performed, and a search result as to whether or not there is an overlap is returned to the network / subscriber data management device 51. If there is an overlap, the process returns to step 608 and repeats until there is no overlap in all the group members (step 609). Next, an input of a start date and time for starting the service as a group is received (step 61).
1). Next, it is determined whether or not the date and time input in step 610 is normal, and the input in step 611 is prompted until the determination result becomes OK (step 612). Next, an input of the number of days to be used as a temporary contract is received (step 613). Next, it is determined whether or not the value input in step 613 does not exceed the specified value, and the input in step 613 is prompted until the value becomes a normal value (step 614). Here, the service end date is calculated by adding the number of days to be used as the temporary contract input in step 613 to the start date and time of starting the service input in step 611 (step 615). Next, the group code of the new joining group is issued and the buffer memory 147 is issued.
(Step 61)
6). Next, the date and time entered in step 611 and the contents of the buffer memory 147 are stored in the temporary contract group start waiting memory 145 of the network / subscriber management device 51 (step 617). FIG. 9 shows a configuration example of the temporary contract group start waiting memory 145. The temporary contract group start waiting memory 145 has a group code 701, a use start date 70
2, an end-of-use date 703 and an area 704 for storing the contents of the buffer memory 147.

With the above procedure, the temporary group configuration contract from the subscriber is terminated. Network / subscriber management device 51
Searches the group data stored in the temporary contract group start waiting memory 145 once a day for those whose start date and time are the same as the date and time at that time. It is stored in the group configuration memory 141 of the subscriber management device 51. After storing, similar to the procedure for registering a group based on the subscriber contract described above,
Terminals constituting the group (mobile communication terminals 81, 8)
2, 83 and the fixed terminal 1) are transferred to each group attribute memory (111, 112, 113) of the exchange (the mobile exchange 11 and the exchange in the fixed network 3). When the data transfer is completed, the service can be used as a temporary contract group.

Next, a system operation and a procedure when a subscriber completes a subscriber contract or a temporary contract with a group and uses a group call according to the present invention will be described with reference to FIG. In FIG. 1, mobile communication terminals 81, 82,
The case where the terminal 83 and the fixed terminal 1 make a group registration contract will be described as an example. The mobile communication terminals 81, 82, and 83 are located in the wireless areas 61, 62, and 63, respectively, and perform a location registration operation to access the memory device 41 of the mobile switching system 11 via the base stations 71, 72, and 73. The location information is stored in the mobile location information memory 101, and the location information is also stored in the mobile communication terminal location information memory 140 of the network / subscriber data management device 51 shown in FIG. Further, if there is a location registration operation, the number of subscribing groups in the group attribute memory 111 of each mobile communication terminal shown in FIG. 4 is not 0, so the location information / network / subscriber management device 51 shown in FIG. The value converted into the local coordinate by the local coordinate conversion device 143 is stored in the local coordinate 301 corresponding to each mobile communication terminal in the group attribute memory 111 of the memory device 41 of the mobile exchange 11. As described above, when the mobile communication terminal moves across wireless zones and an event that the position information is changed occurs, the above-described position registration, regional coordinate conversion, and data storage processing are executed as needed. As for the fixed terminal 1, at the time of the group configuration contract, the network shown in FIG.

48 shows the configuration of the embodiment. The group call waiting list memory 148 stores the number of group members 202 and group member data 203 and 204 corresponding to the group code, and the distance to a designated terminal described later.

In FIG. 10, it is determined whether the telephone number stored in the first group member data of the group call waiting list memory 148 belongs to the mobile communication terminal or the fixed terminal. If there is, the process proceeds to step 808, and if the terminal is a mobile communication terminal, the process proceeds to step 809 (step 807). In the case of a fixed terminal, access is made to the subscriber data of the fixed network in which the fixed terminal is accommodated. Notify the subscriber management device 51. If the call can be received, the network / subscriber management device 51 is notified that the call can be received, and at the same time, the area coordinates 301 of the group attribute memory 111 corresponding to the terminal are transmitted (step 808). If the terminal is a mobile communication terminal, position information of the mobile communication terminal is collected by using the mobile communication terminal position information memory 140 of the network / subscriber management device 51 (step 809). The mobile switching center indicated by the position information is requested to determine whether an incoming call is possible within the wireless area indicated by the position information of the mobile communication terminal. The mobile switching center that has received the request makes a status collation request to the mobile communication terminal (step 810). When the mobile communication terminal issues a response to the state check and the mobile exchange receives the response via the base station, the mobile communication terminal determines that the call can be received, and informs the network / subscriber management device that the call can be received. 51, and at the same time, the area coordinates 301 of the group attribute memory 111 corresponding to the terminal. Also,
If the mobile terminal is out of the range of the wireless area supported by the mobile switching system after performing the location registration and the location is not registered again, or the power of the mobile communication terminal is turned off, the communication terminal Since the mobile communication terminal cannot issue a response to the state check, the network / subscriber management device 5 informs that the call cannot be received and the call cannot be received.
1 (step 811). After the processing of step 808 or 811 is completed, the number of groups who have determined whether incoming calls are possible is added by one (step 811-1), and the number of groups after the addition matches the number of persons registered in the number 202 of group members. (Step 81)
1-2). If they do not match, the process moves to step 807. As a result, steps 807 to 811
Up to the group call waiting list memory 14
This is performed for all telephone numbers except for the telephone number of the calling terminal among the telephone numbers stored in the group member data 203 and 204 of FIG.

After it is determined that all group members can accept incoming calls, the process proceeds to step 812 shown in FIG. Next, data is deleted from the group / call waiting list memory 148 of the network / subscriber management device 51 for the terminal that has transmitted to the network / subscriber management device 51 that the call cannot be received in steps 808 and 811. Then, it is removed from the search target for calling (step 812). Next, it is determined whether or not the call search target exists in the group call waiting list memory 148, and if the list is empty, a call is sent to the user of the mobile communication terminal 81 who has attempted to call the group. Notify that there is no other party to perform (step 81
3, 814), and terminates the service (step 81).
5). If the list is not empty, the selection of the group calling method is accepted (step 816). Next, when the input in step 816 is “0”, the service (step 81) searches for a terminal that is closest to the area where the mobile communication terminal 81 attempting to use the service is located (step 81).
8) If the input is "1", a service for searching and calling the terminal closest to the terminal to which the designated telephone number is assigned (step 819); if the input is "2", regardless of the distance, It shifts to the service (step 820) for performing the simultaneous call (step 817).

Here, "0" is input in step 816, and the process proceeds to step 818 via step 817, that is, the mobile communication terminal 81 which is a constituent terminal of the group is closest to its own terminal. FIG. 13 shows an example of a procedure for performing communication with a terminal at a position. If there is a call search target person in the group call waiting list memory 148, the mobile communication terminal 81 is obtained from the local coordinates of each terminal received in steps 808 and 811 and the local coordinates of the mobile communication terminal 81 received in step 803.
The distance between the terminal and each terminal is calculated (step 901). This result is stored in the group call waiting list memory 148, and the group call waiting list memory 148 is rearranged in ascending order using the distance as a key (step 902). Next, the telephone number of the terminal closest to the head of the group call waiting list memory 148, that is, the mobile communication terminal 81 is called. For the transmission of the mobile communication terminal, the position information of the mobile communication terminal stored in the mobile communication terminal position information memory of the network / subscriber management device 51 is used (step 9).
03). In addition, a method will be described in which, when the calling terminal does not respond, a search for the next closest terminal is performed and the calling is performed sequentially. If the calling terminal responds in step 903, the state transits to the communicating state in both terminals (step 905), and the service processing is terminated by disconnecting one of them (step 911). If the calling terminal does not answer in step 903 and the user of the mobile communication terminal 81 disconnects the call (step 906), the service processing ends (step 91).
1). If the terminal that made the call in step 903 does not answer and the user of the mobile communication terminal 81 performs an operation such as hooking (step 907), the terminal that did not make a response, that is, the group call waiting list memory 148 Erase the first data (step 90
8). Next, the group call waiting list memory 148
In step 909, it is determined whether or not data of the terminal to be called remains, and if not, it is notified that all terminals in the group could not be called (step 910), and the service is terminated (step 910). 912).
If the data of the terminal that makes the call remains in the group call waiting list memory 148, the process proceeds to step 9
03, group call waiting list memory 148
Call the terminal of the first data of. By repeating the above, it is possible to sequentially call the mobile communication terminal 81 in an order close to the mobile communication terminal 81 until the terminal responds.

Next, "1" is input in step 816, and the process proceeds to step 819 via step 817, that is, the mobile communication terminal 81, which is a constituent terminal of the group, determines that the designated telephone number is FIG. 14 shows an example of a service procedure for searching for and calling a terminal closest to the assigned terminal. After the procedure from step 800 to step 820 is completed, the telephone number of the terminal that is the source of the area to be called is accepted (step 1001).
A request is made to the exchange to which the terminal assigned the input telephone number is assigned to check the telephone number, and if the input is not normal, the user of the mobile communication terminal 81 is prompted to input again (step 1002). Next, the area coordinates of the telephone number input in step 1001 are determined. If the input telephone number is that of a fixed terminal, the area coordinates are obtained by using the data stored in the telephone number / area coordinate conversion memory of the network / subscriber management device 51. If the input telephone number is a mobile communication terminal, position information of the mobile communication terminal is obtained from data stored in the mobile communication terminal position information memory 140 of the network / subscriber management device 51, Further, the local coordinates of the mobile communication terminal are obtained from the data stored in the position information / local coordinate conversion device 143 of the network / subscriber management device 51 (step 1003). Next, the area coordinates obtained in step 1003 and step 80
6, the distance between the terminal to which the designated telephone number is assigned and each terminal is calculated from the regional coordinates of each terminal received in step 810 and the group call waiting list memory 1
48. This is sorted in ascending order using the distance as a key (step 1004). After step 1004,
This is the same as the processing from step 904 to step 911.

In step 816, "0" or "1" is input, and the mobile communication terminal 81, which is a constituent terminal of the group, attempts to communicate with the terminal closest to the terminal. Alternatively, in the service procedure for searching for and calling a terminal closest to the terminal to which the telephone number designated by the mobile communication terminal 81 that is a constituent terminal of the group is assigned, in step 905, the group call waiting list memory 148 When the user is talking with the first terminal and wants to call the next closest terminal as it is when the call ends, the user of the mobile terminal terminal 81 performs a hooking operation (step 911).
Moving to step 908, the next terminal can be called. When it is desired to terminate the calling in order, the calling can be performed by disconnecting in the same manner as in step 906.

Next, FIG. 15 shows a state in which "2" is input in step 816 and the process proceeds to step 820 through step 817, that is, FIG. 15 shows an example of a service procedure for performing a simultaneous call regardless of the distance. After the procedure from step 801 to step 820 is completed, a general call is made to the terminals of the group stored in the group call waiting list memory 148 (step 1101).
After making the call, the call is answered first (step 110).
2) A call is established with respect to the terminal, and a transition is made to a busy state (step 1103). After making the call, the mobile communication terminal 81 simultaneously broadcasts a call to a terminal other than the first responding terminal, transfers a message indicating that the other terminal has responded first (step 1104), and disconnects the call. .

Next, FIG. 16 shows an example of a method of calling a group by limiting the calling range. First, the net
The region is divided in advance in the database 144 of the subscriber management device 51, a predetermined number is assigned to each of the divided regions, and the number is stored in association with the region coordinates. In step 803, if "1" is input, the process proceeds to step 805, and then, in order to select whether to limit the area using a number on the database or to specify a telephone number halfway, The former accepts "0" and the latter accepts "1" (step 1201). First,
If "0" is input, the procedure from step 806 to step 820 is performed to create the group call waiting list memory 148 and select the group call procedure (step 1202). Next, an identification number on a database for limiting an area is input (step 120).
3). Next, the group call waiting list memory 14
8 (steps 808, 81)
1) is compared with the range of the area coordinates of the identification number on the database input in step 1202, and the area coordinates on the database do not include the area coordinates of the terminal on the group call waiting list memory 148. In this case, the data of this terminal is deleted. If there is, the data is left on the group call waiting list memory 148 as a terminal to be called (step 120).
4). This collation is used for group call waiting list memory 1
48 for all terminals of the group to be called.

By utilizing the data in the group call waiting list memory 148 created in the above procedure for the procedures of the respective methods shown in FIGS. 13, 14 and 15, a call limited to an area using a database is made. Can be realized.

If "1" is input in step 1201, the procedure from step 806 to step 820 is performed to create the group call waiting list memory 148 and select the group call procedure (step 1).
205). Next, a part of a telephone number for limiting an area is input. In the input mode, the end of the input operation is recognized by inputting an end symbol (# as an example) at the end of a part of the telephone number (step 1206). Step 12
A part of the telephone number input in step 06 is translated and applied to the area created in the database 144 to determine the range of the area to be collated (step 1207). Next, the local coordinates (transferred in steps 808 and 811) corresponding to each terminal in the group call waiting list memory 148 are compared with the range of the local coordinates limited in step 1207, and if there is no match, The data in the group call waiting list memory 148 of this terminal is deleted. If there is, the data is left in the group call waiting list memory 148 as a terminal to be called (step 1207). This check is performed for all terminals of the group to be called on the group call waiting list memory 148. By utilizing the data in the group call waiting list memory 148 created in the above procedure for the procedures of the respective methods shown in FIGS. 13, 14, and 15, a call limited to an area by dialing a telephone number halfway is provided. Can be realized.

It is also possible for a user of a mobile communication terminal and a fixed terminal to make a subscription contract across a plurality of groups. In this case, a method for selecting a group to receive a group call for each terminal will be described. . As an example, it is assumed that the mobile communication terminal 81 has made subscription contracts for three groups. When setting so that only one group can receive a group call in the group, dial a telephone number managed by a specific number form, and receive a user recognition group number 303 ON / OFF setting 30
4 and the data to be stored. ON / OFF of incoming call
Is set in advance as "0" when ON (group calling is possible) and "1" when OFF (group calling is impossible). At the time of calling the group, step 811 (step 80 for a fixed terminal)
When the value of the incoming call ON / OFF setting 304 is “0” in 8), the network / subscriber management device 51 is notified that the incoming call will not be received unconditionally regardless of the state of the terminal. Thereby, a group to receive a call can be selected for each terminal.

When the group registration is performed, when confirming the subscriber telephone number in steps 604 and 606, various data existing in the network / subscriber management device 51 are referred to, and the group registration is permitted. The number of malicious users in the group and the number of group contractors can be limited by providing means for determining non-permission.

When making a group contract temporarily,
Although the person in charge of the group is registered, if there is a terminal that joins the group halfway, a method of inquiring of the person in charge of the group about permission / non-permission of joining can be used. As an example, a method is adopted in which a group manager sets a password in the group member memory in advance, prompts the subscriber to enter a password in the mid-term joining procedure, and permits the group to be joined if the passwords match. By that
This method can be realized.
