Abstract

PURPOSE:To attain efficient communication by revising automatically a group depending on a position of a mobile terminal. CONSTITUTION:Area numbers A1-An in which group selection is effective are registered to a representative group register table 121 together with mobile terminal 11-1n being memberships of the representative group. Suppose that terminals 11, 12, stationary terminals 21, 22 and a valid area A1 are registered to an extension representative group G11, then a call reaching the terminal 11 and when the terminal 11 is busy, the registration table 121 is referenced and a succeeding terminal 12 is selected. In this case, the effective area of the terminal 12 is checked and when the terminal 12 is in the area A1, the call reaches the terminal 12, and when the terminal is not in the area A1, a succeeding terminal or the terminal 21 receives the call. In the case of registration of a representative group, terminal numbers and effective areas are registered in this way and when a mobile terminal is selected through a representative incoming call, the call reception is valid only when the received terminal is in the valid area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for selecting a representative group of an electronic exchange that accommodates a mobile terminal and a fixed terminal and controlling a pickup response.

In recent years, inexpensive and high-performance mobile terminals have been easily obtained, and a switching system accommodating such mobile terminals has been widely put into practical use. Further, with the progress of technology of electronic exchanges and mobile terminals, cordless telephones that can be moved over a wide range by controlling the mobile terminal control area have been used.

In electronic exchanges accommodating fixed terminals, representative selection services and pickup services are widely used as known techniques. Even in an exchange that accommodates a mobile terminal, a representative selection service and a pickup service are required to effectively use the mobile terminal.

2. Description of the Related Art FIG. 8 is a diagram for explaining a conventional example. In the figure, 100 is an electronic exchange, 110 is a maintenance console (shown as MC in the figure) as an input / output device, 120 is a storage device (shown as MM in the figure), and 130 is a central control unit (shown as CC in the figure). ), 140 is a network (indicated as NW in the figure).

CS1 to CS3 are base station devices, 11 to 15 are mobile terminals, and 21 to 23 are fixed terminals. A1 to A3 are areas of the base station devices CS1 to CS3, and when the mobile terminals 11 to 15 are within this range, communication is possible via the base station devices CS1 to CS3.

For example, such registration of the representative selection groups G11 to G12 of the electronic exchange 100 is performed from the maintenance console 110 and written in the representative group registration table 121 in the storage device 120.

For example, it is shown that the representative selection group G11 is composed of mobile terminals 11 and 12 and fixed terminals 21 to 23. Here, when an incoming call is received while the mobile terminal 11 is busy, the representative group registration table 121 is referred to,
The mobile terminal 12 next to the mobile terminal 11 is called. At this time, if the mobile terminal 12 is also busy, the next fixed terminal 21 is called.

In this way, the representative group registration table 12
When the terminal registered in No. 1 receives an incoming call, if the terminal is busy, the terminals registered in the representative group registration table 121 are sequentially searched for vacancy to perform the incoming call processing.

[0009]

In the above-mentioned conventional example, the representative selection group G11 (the same applies to a plurality of representative selection groups) is registered by the maintenance person of the exchange from the maintenance console 110. Therefore, when the registered terminal of the representative selection group G11 is changed, the maintenance person of the exchange must operate the maintenance console 110 to change the registration.

Further, the registration of the pickup group is similarly performed from the maintenance console 110. The representative selection group service and the pick-up service as described above perform efficient communication by forming a group with terminals nearby. However, even if a mobile terminal is included in such a group and the mobile terminal moves away from the group, this terminal cannot be excluded from the group and the representative selection group service and the pickup service cannot be effectively used. Sometimes it happens.

The present invention intends to realize a group selection control method capable of excluding a mobile terminal from a group when the mobile terminal moves away from the terminal group forming the group.

[0012]

FIG. 1 is a diagram for explaining the principle of the present invention. The figure shows mobile terminals 11 to 1n and fixed terminal 2
The group selection control method in the electronic exchange 100 which accommodates 1-2n is shown.

In STEP 1, from the input / output device of the electronic exchange 100, mobile terminals 11 to 1n and fixed terminals 21 to 2 which form a group for each representative selection group G11 to G1n.
n is registered in the representative group registration table 121, and in STEP 2, when the mobile terminals 11 to 1n move and the accommodated area changes, a new area is registered corresponding to the mobile terminals 11 to 1n.

When there is an incoming call to the representative group number, STEP 3 selects the terminal to be called by referring to the representative group registration table 121, and STEP 4 if the selected called terminal is the fixed terminal 21 to 2n. The fixed terminal 2i receives the call, and in STEP 5, the selected called terminal is the mobile terminal 11
In the case of 1n, the incoming call process is performed when the mobile terminal 1j is in the effective area.

[0015]

In the present invention, the representative selection groups G11 to G1n
As arbitrary mobile terminals 11 to 1n and arbitrary fixed terminals 2
1 to 2n are registered in the representative group registration table 121 to form a group.

In the representative group registration table 121, area numbers a1 to an for which group selection is valid are registered together with the mobile terminals 11 to 1n. For example, it is assumed that the mobile terminals 11 and 12 and the fixed terminals 21 and 22 are registered in the extension representative group G11, and the area A1 is registered as the effective area thereof. Here, the mobile terminal 1 in the area A1
When the call arrives at No. 1 and is busy, the next mobile terminal 12 is selected by referring to the representative group registration table 121. At this time, the effective area of the mobile terminal 12 is checked, and if the mobile terminal 12 is in the area A1, the incoming call processing is performed to the mobile terminal 12, and if it is not in the area A1, the next terminal or the fixed terminal 21 performs incoming call processing.

In this way, when the representative group is registered, the terminal number and the effective area are registered in advance, and when the mobile terminal is selected by the representative incoming call, the incoming call processing is performed only when the user is in the effective area. .

Similarly, for the pickup, an effective area is registered in advance so that the pickup can be performed only when the mobile terminal is in the effective area.

[0019]

FIG. 2 is a diagram for explaining an embodiment of the present invention.
In the figure, 100 is an electronic exchange, 110 is a maintenance console, 120 is a storage device, 130 is a central control unit, 14
0 is a network.

CS1 to CS3 are base station devices, 11 to 14 are mobile terminals, and 21 to 23 are fixed terminals. A1 to A3 are areas of the base station devices CS1 to CS3, and when the mobile terminals 11 to 14 are within this range, communication is possible via the base station devices CS1 to CS3.

The representative group registration table 121 and the terminal position management table 122 are provided in the storage device 120 according to the present invention. The representative group registration table 121 includes the terminal numbers constituting the representative group and their effective areas. be registered. If the terminal is a fixed terminal, it is not necessary to specify the effective area. This registration is done through the maintenance console 110. In addition, the terminal location management table 122 includes mobile terminals 11 to 1
When the area number where 4 is located is written and the area where it is located after movement has changed, the area number is updated so that the latest area number is always written.

In this embodiment, the representative group G11 is composed of the mobile terminals 11 and 12 and the fixed terminals 21 to 23, the effective area of the mobile terminals 11 and 12 is the area A1, and the representative group G12 is the mobile terminal 11 and the mobile terminals. In this example, the effective area of the mobile terminals 11 and 14 is area A3.

FIG. 3 is a representative selection processing flowchart (1) according to the embodiment of the present invention. An example will be described when an incoming call arrives in the area A1 having the configuration of FIG. For example, when the mobile terminal 11 designated by the received dial number is busy, the representative selection process is started.

Since the mobile terminal 11 is busy, the mobile station 11 refers to the representative group registration table 121 in which the mobile terminal 11 is registered and reads the terminal numbers registered in the same group. Here, since the mobile terminal 12 is registered next to the mobile terminal 11, the mobile terminal 12 is selected.

It is determined whether the selected terminal is a mobile terminal. If it is a fixed terminal, you can receive the call as it is, so proceed to. When the selected terminal is a mobile terminal, the current position is read by referring to the terminal position management table 122.

It is determined whether or not the current position is within the valid area or area A1, and if it is not within the area A1, the process returns to and the process of selecting the next terminal is executed. If the terminal selected in step 1 is a fixed terminal, and if the terminal selected in step 3 is a mobile terminal and is within the effective area, the incoming call processing for that terminal is executed.

In this way, when the mobile terminal 11 is located in the area A1, the representative group G11 is the mobile terminal 1
1 and 12 and fixed terminals 21 to 23. Since the representative group G12 does not have the mobile terminal 11 in the area A3, only the mobile terminal 14 constitutes the group.

If the mobile terminal 11 moves from the area A1 and enters the area A3, the representative group G1
The mobile terminal 11 is excluded from 1, the representative group G11 is composed of the mobile terminals 12 and the fixed terminals 21 to 23, and the representative group G12 is composed of the mobile terminals 11 and 14. In this way, the representative selection group is automatically changed as the mobile terminal moves.

FIG. 4 is a representative selection processing flowchart (2) according to the embodiment of the present invention. In FIG. 4, an incoming call is made to a mobile terminal located in the same area without performing group registration.

For example, when the incoming mobile terminal 11 is busy, the in-area representative selection process starts. By referring to the terminal location management table 122, the area number a1 in which the mobile terminal 11 is located is read out, and it is identified that it is located in the area A1.

The mobile terminal 12 located in the same area A 1 as the mobile terminal 11 is selected by referring to the terminal position management table 122. It is determined whether the selected mobile terminal is capable of receiving an incoming call, and if the incoming call is not possible, the process returns to and the next mobile terminal is selected.

When the selected mobile terminal can receive an incoming call, the incoming call process is executed. By such processing, it becomes possible to select a representative group in the same area without registering the group.

FIG. 5 is a representative selection processing flowchart (3) according to the embodiment of the present invention. It is the same as in FIG. 4 that an incoming call is made to a mobile terminal located in the same area without performing the representative group registration, but the only mobile terminals that can receive an incoming call are those mobile terminals registered in the representative selection qualification registration table 123. To do.
This representative qualification registration is performed by the maintenance person from the maintenance console 110 in advance, similar to the registration of the representative group.

For example, when the incoming mobile terminal 11 is busy, the in-area representative selection process starts. The same processing as in FIG.
Is selected.

With reference to the representative selection qualification registration table 123, the representative selection qualification of the selected mobile terminal 12 is read. If the selected mobile terminal 12 does not have the representative selection qualification, the process returns to and the next mobile terminal is selected.

If the selected mobile terminal 12 has the representative selection qualification, it is determined whether the incoming call is possible. If the incoming call is not possible, the process returns to and the next mobile terminal is selected. When the selected mobile terminal 12 can receive an incoming call, the incoming call process is executed.

FIG. 6 is a pickup processing flowchart (1) of the present invention. In FIG. 6, the pickup processing is performed by using the pickup group registration table 124 instead of the representative group registration table 121 of FIG. In this pickup group registration table 124, the terminal numbers that form the pickup group and their effective areas are designated. The pickup process will be described below with reference to the flowchart.

Since the terminal that received the call, here the mobile terminal 12, did not respond, the pick-up process is executed by dialing the special pick-up number from the mobile terminal 11.

When the pick-up special number is dialed from the mobile terminal 11, referring to the pick-up group registration table 124 in which the mobile terminal 12 is registered, it is confirmed that the mobile terminal 12 is registered in the same pick-up group as the mobile terminal 11. Check.

It is determined whether the responding terminal 11 is a mobile terminal. In the case of a mobile terminal, referring to the terminal position management table 122, the area number a1 of the current position of the mobile terminal 11 that responded is referred to.
Read out.

It is determined whether or not the area number a1 of the mobile terminal 11 is the same as the area number a1 of the effective area and the area A1 in which the mobile terminal 12 is registered. When the responding mobile terminal 11 is within the area A1, the response process is performed.

FIG. 7 is a pickup flowchart (2) according to the embodiment of the present invention. In FIG. 7, the pickup response is made in the same area without registering the pickup group.

For example, since the mobile terminal 12 that received the call did not respond, another mobile terminal 11 dials the pick-up special number to start the pick-up process. With reference to the terminal position management table 122, the area number a1 of the area where the mobile terminal 11 is located is read.

The area number a 1 in which the mobile terminal 12 is located is read with reference to the terminal location management table 122. It is determined whether or not the read area number a1 and the read area number a1 match.

If the area numbers a1 match with each other, it is possible to pick up, and a response process is performed. By such processing, the pickup group processing can be performed without registering the group.
