Abstract

PURPOSE: To delete or revise subscriber data in a speech state without affecting the speech state by providing tentatively the subscriber data to a pseudo terminal equipment when a delete object subscriber is busy so as to delete registration of a subscriber number or the like from a subscriber data file. CONSTITUTION: The system is made up of subscriber terminal equipments A, B connected via a switch 103, and a control circuit 104 controlling transmission reception sections 101, 102 or the like by using a data memory 105 and a program memory 107. Through the constitution above, when subscriber data of a busy subscriber are deleted, a pseudo terminal equipment not in use at present is set in cross reference with a normal number provided to the subscriber. While the subscriber data are saved and stored in the pseudo terminal equipment, a subscriber number and a subscriber accommodated position in the subscriber data are deleted from a subscriber data file. When the speech is finished, the normal number in cross reference with the pseudo terminal equipment is deleted and the subscriber data are deleted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber data control system in an electronic exchange, and more particularly to a method for deleting and changing subscriber data of a subscriber during a call.

[0002]

2. Description of the Related Art Conventionally, there has been known a line blocking / releasing control system capable of blocking or releasing a line of a telephone as needed so that only a specific person can use the telephone. There is.

For example, in Japanese Unexamined Patent Publication No. Hei 5-236090, a personal identification number known only to a contracting subscriber is registered in an exchange, and by setting the personal identification number, the telephone line is blocked and used by another person. There is disclosed a technique for prohibiting the call and also for resetting the password by setting the password again when the user uses it. As a result, subscriber data control is performed so that the use of telephones other than the contracted subscriber can be prohibited.

On the other hand, in the case of canceling the contract of the contracting subscriber itself, a maintenance person closes the line when the contracting subscriber is not calling and deletes the subscriber data according to a predetermined procedure.

[0005]

As described above, in the conventional method, since the subscriber data can be deleted only when the contracting subscriber is not in a call, when the subscriber to be controlled is in a call,
Subscriber data could not be deleted or changed until the call ended. Also, when changing the accommodation position on the assumption that the subscriber number is used continuously, for example, when the subscriber moves within the same station, if the old accommodation position of the line is busy, the subscriber data is deleted. It is also not possible to register the subscriber data in the new accommodation position. For this reason, there has been a problem that the maintenance work of deleting and changing the subscriber data cannot be performed at the designated time, and the efficiency of the maintenance work of the exchange is lowered.

Therefore, an object of the present invention is to provide a subscriber data control system in an electronic exchange in which subscriber data of a subscriber in a call state can be deleted or changed immediately without affecting the call state. It is in.

[0007]

In order to achieve the above object, the present invention provides a subscriber data file having subscriber data managed by a normalization number given to a contract subscriber, and the subscriber. In an electronic exchange having a pseudo terminal which is a logical subscriber terminal in the exchange to which data can be added, when deleting the subscriber data of a predetermined subscriber terminal when the subscriber to be deleted is in a call, The subscriber data is temporarily given to the pseudo terminal, the registration of the subscriber number and the subscriber accommodating position in the subscriber data is deleted from the subscriber data file, and when the call ends, the subscriber data is deleted. The registration of the subscriber data given to the pseudo terminal is deleted.

[0008]

According to the present invention, when deleting the subscriber data of a subscriber who is in a call state, the pseudo terminal not currently used and the normalization number given to the subscriber are associated with each other. The subscriber number and the subscriber accommodating position of the subscriber data are deleted from the subscriber data file while saving and retaining the data in the pseudo terminal. When the call ends, the normalization number associated with the pseudo terminal is deleted and the subscriber data is deleted.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a system block diagram of an electronic exchange according to an embodiment of the present invention.

In this figure, it is assumed that the subscriber terminal A is accommodated in the transmission / reception unit 101 composed of a plurality of call monitoring circuits, and the subscriber terminal B is accommodated in the transmission / reception unit 102.
The subscriber terminals A and B are connected via a communication path switch 103 interposed between the transmission / reception units 101 and 102,
You can call.

The control device 104 uses the data memory 105 and the program memory 107 to transmit / receive units 101, 1
02 and the switch 103. As described below,
The control device 104 uses the table stored in the data memory 105 and the pseudo terminal program stored in the program memory 107 to delete and change the subscriber data.

The subscriber data file 106 of the data memory 105 stores subscriber data such as subscriber number, subscriber accommodation position, telephone class, billing class, contract service information and the like. Further, in the data memory 105, a correspondence table TBL1 between the subscriber number and the normalized number
And the correspondence table TB between the subscriber accommodation position and the normalized number
Correspondence table T between L2, normalized number and subscriber data
BL3 and a correspondence table TBL4 of a pseudo terminal and a normalized number, which will be described later, are provided. Here, the normalized number is a number given to the contracted subscriber in the exchange, and the subscriber data is managed by this.

In the program memory 107, a plurality of logical subscriber terminals (pseudo terminals) to which subscriber data can be added within the exchange (in this embodiment, three subscriber terminals X, Y, Z) are provided.
One) has been created. The pseudo terminal is capable of calling, connecting, and forming a call path of a subscriber. In other words, the pseudo terminal physically connects the subscribers A and B, who are in a call state with the pseudo terminal, to the subscribers A and B as a logical subscriber terminal without the intervention of the pseudo terminal. With function.

FIG. 2 is an explanatory view showing the function of the pseudo terminal. Based on this figure, the function of the pseudo terminal will be described step by step.

First, in step (1), the pseudo terminal X is selected, and in step (2), the pseudo terminal X calls the subscriber A.

When subscriber A receives a call, step (3)
Then, the pseudo terminal X further calls the subscriber B.

As shown in step (4), the pseudo terminal X
The subscribers A and B are connected to each other via, and finally, as shown in step (5), the subscribers A and B are physically connected without the intervention of the pseudo terminal X.

FIG. 3 is a flow chart for explaining a subscriber data control method according to an embodiment of the present invention.

The subscriber data control system of this embodiment specifically shows procedures for deleting subscriber data and newly registering during a call. The outline of the contents will be described below for each stage.

First, in step (1), it is assumed that the subscriber A and the subscriber B are in a call state. Here, when deleting the subscriber data of the subscriber A, as shown in step (2), the subscriber data is temporarily given (saved) to the pseudo terminal X which is not currently used, and the subscriber A joins. Only the subscriber number and subscriber accommodation position in the personal data are deleted.

When the subscriber C is registered here, the subscriber data of the subscriber A is registered in the subscriber C as shown in step (3). In the above steps (2) and (3),
Since the pseudo-terminal X holds the subscriber data of the subscriber A, the call between the subscriber A and the subscriber B can be performed without any trouble.

Then, as shown in step (4), when the call between the subscriber A (pseudo terminal X) and the subscriber B is completed, all the subscriber data of the subscriber A is deleted.

(Subscriber deletion) FIG. 4 is an explanatory diagram showing data changes in each table (TBL) during a call when a subscriber is deleted. (A) shows changes in TBL1 and (b) shows T.
BL2 changes, (c) TBL3 changes, and (d) TBL4 changes. Here (a)
In (d), the table on the left shows the original one, and the table on the right shows the one after the subscriber A of the subscriber A is deleted during the call.

The subscriber deleting operation will be specifically described below with reference to FIG. 4 and FIG.

As shown in FIG. 4 (a), the subscriber number "85-1111" of the subscriber A and the normalized number "1" of the subscriber A and the subscriber number "85-22 of the subscriber B" are initially stored in the TBL1.
22 "and the normalization number" 3 "are registered.

Similarly, as shown in FIG.
Initially, the subscriber accommodation position of the subscriber A is “000301” in 2
00 "and the normalization number" 1 ", the subscriber accommodation position" 00030110 "of the subscriber B and the normalization number" 3 "are registered.

As shown in FIG. 4C, TBL3
Initially, the normalization number “1” of the subscriber A and the subscriber data “XXX”, and the normalization number “3” of the subscriber and the subscriber data “ΔΔΔ” are registered.

As shown in FIG. 4D, TBL4
Initially, only the pseudo terminals X, Y, and Z are registered, and the normalization numbers corresponding to the pseudo terminals are not registered.

In this state, as shown in (1) of FIG.
When deleting the subscriber data of the subscriber A who is in a call with the subscriber B, the subscriber A who is the deletion target of the subscriber data
The control device 104 (see FIG. 1), which has detected that the call is in progress, confirms that there is a pseudo terminal X that is not currently used, and as shown in (d) of FIG.
At, the pseudo terminal X is associated with the normalization number “1” given to the subscriber A to be deleted.

Next, the control device 104 deletes the registration of the subscriber number and the subscriber accommodation position of the subscriber A. That is, FIG. 4 is a correspondence table of subscriber numbers and normalized numbers.
The subscriber number "8" of the subscriber A from TBL1 shown in (a) of
5-1111 "is deleted, and the subscriber accommodation position" 00030100 "of the subscriber A is deleted from TBL2 shown in FIG. 4B which is a correspondence table of the subscriber accommodation position and the normalized number.

As described above, the subscriber data of the subscriber A and the assigned normalization number are taken over by the pseudo terminal X by associating the pseudo terminal X with the normalization number "1" in the TBL4. Therefore, the call between the subscriber A and the subscriber B is logically the call between the pseudo terminal X and the subscriber B [state (2) of FIG. 3], but the in-call state is not affected.

As shown in FIG. 4C, the TBL
Since the subscriber data corresponding to the normalized number "1" in No. 3 is not deleted, the subscriber data of the subscriber A is the subscriber number "85-1111" and the subscriber accommodation position "000."
This means that the pseudo terminal X has taken over without having a relationship with 30100 ″.

(Subscriber new registration) FIG. 5 is an explanatory diagram showing data changes in each table during a call when new subscriber data is registered. FIG. 5A shows a change in TBL1 and FIG.
Shows changes in TBL2, and (c) shows changes in TBL3. In (a), (b), and (c), the left table shows before registration, and the right table shows after registration.

Referring to FIG. 5 and FIG. 3 described above, when the pseudo terminal X and the subscriber B are in a call state, the subscriber number "85-1111" used by the subscriber A is changed to another one. The operation when assigning to the subscriber C will be described.

An example of the case where the subscriber C has inherited the subscriber number used by the subscriber A is moving within the same station. In this case, the subscriber A and the subscriber C have substantially the same contract. Can be called a person.

The subscriber number of the subscriber C is "85-111".
1 "and the subscriber accommodation position is" 00030120 ", the control device 10 that has accepted the registration command of the subscriber C
4 assigns an unused normalization number “5” to the subscriber C, and the correspondence table TBL1 between the subscriber number and the normalization number shown in (a) of FIG. 5 and the subscription shown in (b) of FIG. A correspondence table TBL2 between the person accommodation position and the normalization number,
A correspondence table TBL3 of the normalized number and the subscriber data shown in (c) is created.

At this time, in the TBL 3 shown in FIG. 5C, the subscriber data having the normalization number "1" associated with the pseudo terminal X and the normalization number "5" associated with the subscriber C are stored. The subscriber numbers in both are "85-1111", but the subscriber number "85" is used as information for identifying the pseudo terminal.
By using the pseudo terminal number X instead of -1111 ", the subscriber number" 85-1111 "can be duplicated, and independent operation between the pseudo terminal X and the subscriber C is guaranteed.

Therefore, after the registration of the subscriber C is completed,
The subscriber C can make and receive calls regardless of the call state between the pseudo terminal X and the subscriber B [state (3) in FIG. 3].

(End of pseudo terminal call) FIG. 6 is an explanatory diagram showing a change in data in each table before and after the end of the pseudo terminal call when the subscriber data is changed, and FIG. 6A shows a change in TBL3.
(B) shows changes in TBL4.

The operation when the call between the pseudo terminal X and the subscriber B is completed will be described with reference to FIG. 6 and FIG.

The control device 104, which has detected the end of the call between the pseudo terminal X and the subscriber B, obtains the normalization number "1" associated with the pseudo terminal X from the TBL4 shown in FIG.
The normalization number “1” associated with the pseudo terminal X is deleted from TBL4, and TBL3 shown in FIG.
Subscriber data “×” corresponding to the normalized number “1” in
XX "is deleted. Therefore, the contract information of the subscriber A is completely deleted when the call between the pseudo terminal X and the subscriber B ends.

[0043]

As described above, the subscriber data control method in the electronic exchange according to the present invention enables the maintenance person to efficiently delete the subscriber data even when the contract subscriber is busy. It is possible to perform the work for a long time, and it is also possible to register a new subscriber at a designated time, so that the serviceability can be improved.
