Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simultaneous call system, and is a simultaneous call that calls a larger number of mobile terminals than the number that can be called at the same time, especially in an exchange that has a limited number of mobile telephones such as mobile phones and PHS. Regarding the method.
[0002]
[Prior art]
A configuration diagram of a conventional system will be described. In FIG. 6, reference numerals 101, 102, 103, 104, 201, 202, 203, and 204 denote mobile terminals that communicate with the transceiver 2 via radio waves. Reference numeral 1 denotes an exchange connected to the transmitter 2. Reference numeral 30 denotes a database provided in the exchange 1. Reference numerals 41, 42, and 43 are telephone terminals connected to the exchange 1. A description of the database is shown in FIG. FIG. 7 is a table in which mobile terminals are grouped. In the group 100, mobile terminals 101, 102, 103, and 104 belong, in the group 200, mobile terminals 201, 202, 203, and 204 belong, and in the group 300. Indicates that the mobile terminals 101, 201, 103, and 204 belong.
[0003]
When the telephone terminal 41 performs a call operation on the mobile terminal 101, the exchange 1 secures a communication path with the mobile terminal 101 through the transmitter 2 and can realize a one-to-one call. When the telephone terminal selects the group 100 and makes a general call, the exchange 1 retrieves the mobile terminal number that makes a simultaneous call from the table for grouping the mobile terminals configured in the database 30 and moves from the transmitter 2 to belong to the group 100. Call terminals 101, 102, 103, 104. When any of the mobile terminals responds to the call, the simultaneous call ends, the responding mobile terminal and the telephone terminal talk, and the mobile terminal that does not respond is on standby. Alternatively, when the telephone terminal interrupts the call, all the mobile terminals are on standby.
[0004]
When it is desired to call both the group 100 and the group 200 under the condition that the number of mobile terminal devices that can perform simultaneous calls is limited, for example, when the number of simultaneous calls is limited to 4, the mobile terminals 101, 102, Select 4 units from 103, 104, 201, 202, 203, 204, prepare group 300 and set 101, 201, 103, 204, for example, and call all 8 terminals It is not possible.
[0005]
[Problems to be solved by the invention]
However, in such a simultaneous call method, since the number of simultaneous calls is limited, there is no method that can cope with the case where the number of mobile terminals to be called is larger than the number of simultaneous calls.
The present invention has been made to solve such a problem, and aims at a simultaneous calling method that is not limited by the number of simultaneous calls.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the simultaneous calling method according to the present invention is a method for simultaneously calling a mobile terminal switch such as a mobile phone or a PHS having a condition that the number of simultaneous calls is limited. A database device for registering and managing a plurality of mobile terminals as a group is provided in the exchange, and by changing the mobile terminals to be sequentially called, a larger number of mobile terminals are called than can be simultaneously called. And dashi method.
[0007]
In this simultaneous call system, the exchange stores the relationship between groups and mobile terminals in the database device, and simultaneously stores a plurality of groups as the relationship between groups. When a call is made to a group, the switch refers to the relationship between the group and the group, and even if the switch has a limit on the number of calls by changing the group to be called after a specified time, it calls a mobile terminal that exceeds the number of calls. be able to.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of simultaneous calling according to the present invention will be described with reference to a system configuration diagram. In FIG. 1, reference numerals 101, 102, 103, 104, 201, 202, 203, and 204 denote mobile terminals that communicate with the transceiver 2 via radio waves. Reference numeral 1 denotes an exchange connected to the transmitter 2. Reference numeral 30 denotes a database provided in the exchange 1. Reference numerals 41, 42, and 43 are telephone terminals connected to the exchange 1. The description of the database is shown in FIGS. FIG. 2 is a table showing the relationship between groups and mobile terminals. The group 100 includes mobile terminals 101, 102, 103, and 104, and the group 200 includes mobile terminals 201, 202, 203, and 204. ing. FIG. 3 is a table showing the relationship between groups. Group 51 shows group 100, group 52 shows group 200, and group 53 shows group 100 and group 200.
[0009]
The operation will be described based on the flowchart shown in FIG. When the telephone terminal 41 designates the group 53 and makes a simultaneous call, the exchange detects the simultaneous call using the group and sets 1 to the group designated value (ST-1). The group 100 is read first in the group designation value indicated by the group 53 in FIG. Since the group exists (ST-3), 101, 102, 103, and 104 belonging to the group 100 in FIG. 2 showing the relationship between the group and the mobile terminal are extracted as the mobile terminal numbers to be called (ST-4). 1 is added to the group designation value to obtain 2 (ST-5). A general call is executed (ST-6). Wait until the mobile terminal answers the call (ST-7) or the telephone terminal interrupts the call (ST-8). When the predetermined time has passed (ST-9), the group 200 is extracted by referring to the group designation value shown in FIG. 3 showing the relationship between the groups (ST-2), and the following processing is repeated. When the group 200 also does not respond, in (ST-2), the group designation value is 3 and the group 53 is referred to by FIG. 3 showing the relationship between the group and the group. However, since the group number does not exist (ST-3) Then, the group designation value is set to 1 (ST-1), and the group 53 is referred again with reference to FIG. 3 showing the relationship between the group and the group (ST-2).
[0010]
As is clear from the above description, if the group to be called after a specified time is changed, a mobile terminal exceeding the number of simultaneous calls can be called even by an exchange having a limit on the number of simultaneous calls.
[0011]
In the above method, simultaneous calls are made in units of groups, but there is a method of making simultaneous calls across groups. The operation will be described based on the flowchart shown in FIG. The number that can be called simultaneously is four. When the telephone terminal 41 designates the group 53 and makes a simultaneous call, the exchange detects the simultaneous call using the group and sets 1 to the terminal designated value for each group (ST-41). Set 1 to the group specification value. (ST-42). In FIG. 3 showing the relationship between groups, the group 53 is selected, and the first group 100 is extracted from the group designation value (ST-43). Since a group exists (ST-44), 1 is added to the group designation value to obtain 2 (ST-45). The first 101 is extracted from the column of the group 100 in FIG. 2 showing the relationship between the group and the mobile terminal, with the group 100 terminal designated value as the element number (ST-46). Since there is a terminal (ST-47), 1 is added to the group 100 terminal specified value to obtain 2 (ST-49). Since the number of extractions is smaller than the number of calls simultaneously (ST-50), the group 53 is selected in FIG. 3 showing the relationship between the groups and the groups, the second group 200 is extracted from the group designation value, and the process returns to ST-43. Since there is a group (ST-44), 1 is added to the group designation value to obtain 3 (ST-45). The first 201 is extracted from the column of the group 200 in FIG. 2 showing the relationship between the group and the mobile terminal, with the group 200 terminal designated value as the element number (ST-46). Since the terminal exists (ST-47), the group 200 terminal designated value is set to 2 (ST-49). Since the number of extractions is smaller than the number called simultaneously (ST-50), the group 53 is selected in FIG. 3 showing the relationship between the group and the group, and the third group is selected from the group designation value (ST-43). Since there is no group (ST-44), 1 is set to the group designation value (ST-42), and the group 100 is selected again with reference to the group 53 from FIG. 3 showing the relationship between the group and the group (ST-43). . In the same manner, 102 is extracted. When 202 is extracted, the number of extractions reaches the number to be called simultaneously (ST-50), and the simultaneous call is executed (ST-51). Wait until the mobile terminal answers the call (ST-52) or the telephone terminal interrupts the call (ST-53). When the predetermined time has passed (ST-54), the terminal designation value is used as the element number in the same manner, the third 103 of the group 100, the third 203 of the group 200, the fourth 104 of the group 100, and the group 200. The fourth call 204 is extracted as a mobile terminal number to be called, and a simultaneous call is made. When the fixed time has elapsed (ST-54), the group designation value is 3, the group 100 terminal designation value is 5, and the group 200 terminal designation value is 5. The process is repeated from (ST-43), and since the third group 53 does not exist in FIG. 3 showing the relationship between groups (ST-44), the group designation value is set to 1 (ST-42), The first group 100 of the group 53 is obtained (ST-43). When the group 100 is checked with the group 100 terminal designation value in FIG. 2 showing the relationship between the group and the mobile terminal, there is no terminal number (ST-47), and the group 100 terminal designation value is set to 1 (ST-48). The group 100 is checked again to obtain 101 (ST-46). Processing continues below.
