Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extension telephone system, a radio telephone, and a switch capable of changing an extension number of an extension telephone, and more particularly to a radio telephone used as an extension telephone. The present invention relates to an extension number system, a wireless telephone, and an exchange.

[0002]

2. Description of the Related Art In recent years, PHS (Personal Handyphone Sys)
Wireless telephones such as tems (simplified portable telephones) are used as extension telephones on premises. When using the PHS, the private branch exchange (PBX; Private Branch eXc)
hange) and a plurality of base stations (CS; Cell Station) are installed, and the PHS is used by being wirelessly connected to the base station.

When the extension number of the PHS is changed, the PHS
It is necessary to change both the PS data (data indicating the extension number of the PHS) and the office data of the private branch exchange (data indicating the extension number of each telephone connected to the private branch exchange). There are two methods described below.

[0004] The first method is to set the PS data setting machine to PHS.
Connect to the main unit and operate the PS data setting device to change the PS data. In the second method, a maintenance terminal installed in the private branch exchange is operated to output a number change signal from the private branch exchange to the PHS. Then, the PHS is operated according to the instruction of the number change signal to change the PS data.

A technique for changing the extension number of a telephone is disclosed in JP-A-59-224994 and JP-A-62-26946.
No. 5 discloses this. JP-A-59-224994
In the technology disclosed in Japanese Patent Publication No.
A number (sign) for changing the extension number is input by operating a button on the telephone. The main unit (exchange) determines whether or not this number (code) is correct, and blinks the indicator lamp of the telephone according to the determination result. When it is indicated that the previously input number (code) is correct, the telephone user inputs the first digit of the extension number to be changed. The main device determines whether or not the input first digit number is usable as an extension number, and blinks the indicator lamp of the telephone according to the determination result. If the phone user indicates that the first digit entered is available (correct),
Enter the second digit. Thereafter, the same determination by the main device as described above and the input of the number by the telephone user are repeated, and the extension number stored in the main device is changed.

In the technique disclosed in Japanese Patent Application Laid-Open No. 62-269465, an extension number is given to each telephone and each user (subscriber) of the telephone. When the subscriber changes the extension number of the telephone to the extension number given to him, he dials the number for changing the extension number and his extension number. The exchange changes the telephone extension stored therein to the number dialed by the subscriber.

[0007]

When the extension number of a PHS (wireless telephone) is changed by operating a PS data setting machine or a maintenance terminal, complicated settings, exchanges, PHS, and network number planning are required. Requires specialized knowledge.
Therefore, there is a problem that a general PHS user cannot change the extension number.

Further, since the PS data has many parameters and is complicated, there is a problem that information other than the information on the extension number may be erroneously rewritten. In the technique disclosed in Japanese Patent Application Laid-Open No. 59-224994, the extension number is changed one digit at a time, as described above, so that there is a problem that efficiency is low and time is required.

The PHS stores the assigned extension number and the like as the PS data. The PHS uses the PS data to display the extension number on a display or the like, and the PHS user confirms the extension number of the PHS used by the user via the display or the like. Therefore, if you do not change the PS data even if you change the extension number,
Because the extension number before change is displayed on the display etc.,
PHS cannot be used properly as an extension phone. Therefore, when changing the extension number of the PHS, the extension number of the PS data stored in the PHS must be changed.

However, in the technology disclosed in JP-A-59-224994 and JP-A-62-269465, only the extension number stored in the exchange is changed and stored in the PHS (wireless telephone). Extension cannot be changed. Therefore, there is a problem that these techniques cannot be applied to a wireless telephone used as an extension telephone.

The class γ indicates that only the services that can be normally used by the PHS terminal 40 used as the extension telephone are available. In the office data of the exchange 10, the above information is stored in association with an individual PS number indicating an extension telephone and an individual telephone number.

Next, a description will be given of an operation of changing the extension number of the PHS terminal 40 in the extension telephone system configured as described above. The user of the PHS terminal 40
An access code for changing an extension number by operating a button of the input unit 42 and a new extension number (new extension number)
Enter The input access code and new extension number are transmitted to the exchange 10 via the radio base station 20.

The control unit 13 of the exchange 10
0 when the access code is received via the internal memory 1
2 starts a program recorded in advance, and starts an extension number changing process described below. FIG. 3 is a flowchart showing the extension number changing process performed by the control unit 13 of the exchange 10.

First, the control unit 13 determines whether there is a problem with the new extension number input via the line switching unit 11 (step 100). Numbers that can be used for extension numbers are determined in advance by a numbering plan. For example, 1
Is an access code for changing the extension number,
The four-digit number (3xxx) starting with 3 is the extension number of the PHS terminal 40, and the four-digit number (4xxx) starting with 4 is the extension number of the wired telephone 30. The control unit 13 determines whether the input new extension number matches the numbering plan, and if not, determines that there is a problem with the new extension number. Further, the control unit 13 determines whether or not the input new extension number is already used by another PHS terminal 40, and if it is used, determines that there is a problem with the new extension number.

If there is a problem with the new extension number (step 100; YES), the control unit 13 sends a re-input request signal requesting re-input of the new extension number via the line switching unit 11 and the radio base station 20. The extension number is output to the PHS terminal 40 (step 190), and the extension number changing process ends. Upon receiving the re-input request signal, the PHS terminal 40 notifies the user of the message that the input new extension number cannot be used by voice or the like, and the user of the PHS terminal 601 again transmits the access code and the new extension number. input.

If there is no problem with the new extension number (step 100; NO), the control unit 13 outputs a PS data rewrite signal for instructing the PHS terminal 40 to rewrite the PS data via the radio base station 20. (Step 110).
The control unit 45 of the PHS terminal 40
In response to the input of the data rewrite signal, the extension number of the PS data stored in the internal memory 44 is rewritten to the new extension number. Then, a rewrite end signal indicating that the rewriting of the PS data has been completed is returned to the exchange 10.

Control unit 13 of exchange 10 determines whether or not a rewrite end signal is received from PHS terminal 40 within a predetermined time (step 120). When the rewriting end signal is not received within the predetermined time (step 120; NO), the control unit 13 recognizes that some problem has occurred in the PHS terminal 40 and the PS data has not been rewritten, and changes the extension number. The process ends.

When the rewriting end signal is received within a predetermined time (step 120; YES), the control unit 13 determines from the station data in the internal memory 12 the extension number (old extension number) used by the PHS terminal 40. Then, it is determined whether or not one of the extension numbers assigned to the wired telephone 30 matches (step 130). If they match (step 13
0; YES), the control unit 13 sets the extension / PS bit of the wired telephone 30 to which the old extension number is assigned from 1 to 0.
(Step 140).

Next, the control unit 13 determines whether or not the input new extension number matches one of the extension numbers assigned to the wired telephone 30 (step 15).
0). In step 130, if the old extension number does not match the extension number of the wired telephone 30 (step 13).
0; NO), the control unit 13 performs the process of step 150.

If they do not match (step 150; N
O), the control unit 13 transmits the PHS terminal 4 corresponding to the station data.
The extension number of 0 is rewritten to the new extension number that has been input, the class is registered as γ (step 200), and the extension number change process ends. By this processing, the PHS terminal 40
Becomes available only for services normally available to the PHS terminal 40 used as an extension telephone, and is registered with a new extension number. After rewriting the station data, the PHS
Perform normal location registration at the terminal 40, and use the new extension number for PHS
The terminal 40 can be used.

If they match (step 150; YE)
S), the control unit 13 sets 1 to the extension / PS bit of the wired telephone 30 having the same extension number as the new extension number (step 160). Then, the control unit 13 sets the class of the PHS terminal 40 to the wired telephone 30 whose extension number matches.
And the PHS terminal 40 is registered with the new extension number (step 170).

Thereafter, the control unit 13 transmits the class information (information of available services) to the PHS terminal 40 (step 180), and ends the extension number changing process. By this processing, the PHS terminal 40 can use the same service as the wired telephone 30 having the same extension number.
For example, if information on speed dials usable in the wired telephone 30 is transmitted as class information, the same speed dials can be used in the PHS terminal 40.

As described above, the PS data of the PHS terminal 40 and the station data of the exchange 10 can be rewritten only by operating the button of the input section 42. That is, PH
The extension number can be changed only by operating the button of the input unit 42 on the S terminal 40. Therefore, even a user of the PHS terminal 40 who does not have specialized knowledge can easily change the extension number. PHS terminal 4
If the new extension number 0 and the extension number of the wired telephone 30 match, the class information of the wired telephone 30 is transmitted to the PHS terminal 40, so that the PHS terminal 40 uses the same service as the wired telephone 30 Can be. Thereby, for example, when moving within the premises, the PHS terminal 40
Is changed to the extension number of the wired telephone 30 that is usually used, and the user can use the same extension number and service as the wired telephone 30 that is usually used.

Next, the operation of the extension telephone system when a call is made from one extension telephone (wired telephone 30 or PHS terminal 40) to another extension telephone will be described. A user of a certain extension telephone operates a button or the like to input an extension number of another extension telephone.

The input extension number is transmitted to the exchange 10 via the radio base station 20. Control unit 1 of exchange 10
3 receives the extension number via the radio base station 20,
A program pre-recorded in the internal memory 12 is started, and the following line connection processing is started. FIG. 4 is a flowchart showing a line connection process performed by the control unit 13 of the exchange 10.

First, the control unit 13 determines whether there is a problem with the extension number input through the line switching unit 11 (step 310). Numbers that can be used for extensions are
As described above, it is determined in advance by the numbering plan. The control unit 13 determines whether or not the input extension number matches this number plan, that is, whether or not the input extension number is a number that can be used as an extension number.

If there is a problem (step 310; YE
S), the control unit 13 transmits a message to the effect that the input extension number is not used to the PHS terminal 40 (step 360), and ends the line connection processing. If there is no problem (step 310; NO), the control unit 13 determines whether the input extension number is the extension number of the wired telephone 30 using the station data in the internal memory 12 (step 310). 320).

If it is not the extension number of the wired telephone 30, that is, if the input extension number is the number of the PHS terminal 40 (step 320; NO), the control unit 13
Outputs a line switching instruction to the line switching unit 11 in order to connect the telephone having the extension number input thereto and the line of the PHS terminal 40 having the input extension number (step 370), and terminates the line connection processing.

If it is the extension number of the wired telephone 30 (step 320; YES), the control unit 13 determines whether the extension / PS bit of the wired telephone 30 is 1 (step 330). If the extension / PS bit is not 1 (step 330; NO), the control unit 13 switches the line so as to connect the line of the extension telephone to which the extension number has been input and the line of the wired telephone 30 having the input extension number. Part 1
1 (step 380), and terminates the line connection process.

If the extension / PS bit is 1 (step 330; YES), the control unit 13 sets the PHS terminal 4 having the same extension number as the extension number of the wired telephone 30.
0 is detected (step 340). And the control unit 13
Outputs a line switching instruction to the line switching unit 11 so as to connect the extension telephone into which the extension number has been input and the line of the PHS terminal 40 having the input extension number (step 350).
The line connection processing ends.

As described above, the wired telephone 30 and the PH
The fact that the extension number of the S terminal 40 is the same is indicated by the fact that the extension and the PS bit of the station data are 1, and the extension telephone that has reached the wire telephone 30 is replaced with the PH of the same number.
An incoming call can be made to the S terminal 40.

Next, the operation of the extension telephone system will be described with reference to a specific example. Wired telephone 30 and PHS terminal 4
0 is assumed to be three each. The individual telephone numbers of the wired telephone 30 are 701, 702,
703 and the extension number is 4000, 4001, 40
02, the extension and PS bits are all 0, and the classes are α, β, and β. The individual PS numbers of the PHS terminal 40 are 601, 602, and 603, respectively, the extension numbers are 3000, 3001, and 3002, and the class is all γ. Therefore, the office data recorded in the internal memory 12 of the exchange 10 is as shown in FIG. In the following, each wired telephone 30 and each PHS terminal 40 are referred to as a wired telephone 701, a wired telephone 702, a wired telephone 703, a P
HS terminal 601, PHS terminal 602, PHS terminal 603
It expresses.

As a first specific example, a case where the extension number of the PHS terminal 601 is changed from 3000 to 3002 will be described. First, a user of the PHS terminal 601 operates a button of the input unit 42 to input an access code and a new extension number in order to change an extension number. When the access code is set to 1, for example, the input is 1 + 3002 (access code + new extension number).

The control unit 13 of the exchange 10
0 when the access code is received via the internal memory 1
2 is started, and the extension number changing process shown in FIG. 3 is started. First, the control unit 13
Determines whether there is a problem with the input new extension number (step 100).

In this case, the input new extension number 3002
Is already used in the PHS terminal 603. Therefore,
The control unit 13 determines that there is a problem with the new extension number (step 100; YES), and sends a re-input request signal requesting re-input of the new extension number to the line switching unit 11 and the radio base station 20.
Is output to the PHS terminal 601 via the
0), the extension number changing process ends. PHS terminal 601
Receives the re-entry request signal from the exchange 10 and notifies the user by voice or the like of a message indicating that the inputted new extension number cannot be used. And the PHS terminal 60
User 1 inputs the access code + new extension number again.

As a second specific example, a case where the extension number of the PHS terminal 601 is changed from 3000 to 4001 will be described. In the same manner as above, the user of the PHS terminal 601 checks the access code and the new extension number (1 + 400
Enter 1). Upon receiving the access code, control unit 13 of exchange 10 starts the extension number changing process shown in FIG.

In this case, there is no problem with the input new extension number (step 100; NO), so the control unit 13
A PS data rewrite signal is output to the HS terminal 601 (step 110). The control unit 45 of the PHS terminal 40 rewrites the extension number of the PS data stored in the internal memory 44 in response to the input of the PS data rewriting signal from the exchange 10. In this case, the extension number must be between 3000 and 4001.
Rewrite to Then, control unit 45 transmits a rewrite end signal to exchange 10.

Control unit 13 of exchange 10 receives the rewrite end signal within a predetermined time (step 120; YES), and the old extension number (3000) matches any one of the extension numbers assigned to wired telephone 30. It is determined whether or not to perform (step 130). In this case, since they do not match (step 130; NO), the control unit 13 sends the new extension number (40
01) matches any of the extension numbers assigned to the wired telephone 30 (step 15).
0).

In this case, they match (step 15
0; YES), the control unit 13 sets 1 to the extension / PS bit of the wired telephone 702 whose extension number is 4001 (step 160). The control unit 13 controls the PHS terminal 601
Is rewritten to the class (β) of the wired telephone 702, and the PHS terminal 601 is registered with the new extension number (step 170).

Then, the control unit 13 controls the PHS terminal 601
Then, the class information of the wired telephone 702 (information of available services) is transmitted (step 180), and the extension number changing process ends. By the above processing, the station data recorded in the internal memory 12 of the exchange 10 is rewritten as shown in FIG.

As a third specific example, PH in the second specific example
A case will be described in which the extension number of the S terminal 601 is changed to 4001 and then an extension call is made from the wired telephone 701 to the wired telephone 702. The user of the wired telephone 701

In this case, they match (step 13
0; YES), the control unit 13 sets the extension / PS bit of the wired telephone 702 whose extension number is 4001 to 0 (step 140). Then, control unit 13 determines whether or not the new extension number (3003) matches one of the extension numbers assigned to wired telephone 30 (step 150). In this case, there is no match (step 15
0; NO), the control unit 13 sets the class of the PHS terminal 601 to β, rewrites the extension number from 4001 to 3003 and registers it (step 200), and ends the extension number change process.

As described above, the extension number can be changed only by operating the button of the input unit 42 on the PHS terminal 40. Therefore, PHS without expertise
Even the user of the terminal 40 can easily change the extension number. When the new extension number of the PHS terminal 40 matches the extension number of the wired telephone 30, the class information of the wired telephone 30 is transmitted to the PHS terminal 40. Can be used.

Further, the fact that the extension number of the wired telephone 30 is the same as the extension number of the PHS terminal 40 is indicated by the fact that the extension and PS bit of the office data are 1, and the extension telephone that has reached the wired telephone 30 is the same. A call can be made to the PHS terminal 40 of the number. If it is not necessary for someone other than the person concerned to change the extension number without permission, configure the access code to change the extension number with multiple character strings like a password and notify only the person concerned. What should I do?

The PHS terminal 40 has a display unit, and responds to the input of the re-entry request signal transmitted from the exchange 10 in step 190 of the extension number changing process, and sends a message to the effect that the new extension number entered cannot be used. It may be displayed to notify the user.

[0073]

As is apparent from the above description, it is possible to change the extension number stored in the extension telephone and the exchange simply by inputting the extension number to be changed from the extension telephone. Therefore, even a user of the extension telephone having no special knowledge can easily change the extension number.
