Abstract

PURPOSE:To perform a camp-on registration by a simple operation of a call originating side even when the other dialed party telephone set is busy and the other extension makes a response by performing a monitoring control in a busy state in the telephone call between terminals. CONSTITUTION:When a user of a terminal 11 calls to a terminal 12-1, the number of the terminal 12-1 is dialed by the terminal 11. However, when the terminal 12-1 is busy with a terminal 14, a main controller 16 stores numbers dialed by the terminal 11 in call recessing data bloc 17-2. In this case, the terminal 12-1 at the dialed destination is combined with the representitive of extension so that when the terminal 12-2 is idle, it takes a YES route. At the next stage, a response for an originating call from the terminal 11 is performed by the terminal 12-2 and it becomes a busy state. In this case, a user of the terminal 11 is not informed that the terminal 12-1 is busy until the calling of the terminal 12-2 and the user, and then it operates the camp-on registration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camp-on control system for an exchange.

[0002]

2. Description of the Related Art In a conventional camp-on control system, for example, in a private branch exchange, when a calling party B is busy, special number information or the like is input while listening to a busy tone. By performing the camp-on registration operation, it is possible to wait for the other party B to finish talking and to make a call.

As a result, the caller A can wait for the other party B who is busy to make a call only once and wait for the other party B to finish talking, and then automatically make an incoming call. It is possible to save the trouble of making a call.

[0004]

However, due to the diversification of the services of private branch exchanges in recent years, when the telephone number of the other party forms a representative group, for example, when the other party B whom the subscriber A wants to speak is busy. At this time, another person C may respond from an extension other than the partner B. Here, calling party A
For the first time, another person C who answers the telephone informs that the person B who wants to talk is busy. As a result, in such a case, the caller A could not perform the camp-on registration for the party B who wants to talk.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 61-19268, in the above case, the camp-on registration to the other party B is performed by the operation of another person C who responds to the call. Something that can be done is also proposed. However, in this method, the camp-on operation is entrusted to another person C other than the caller A, and it is not possible to confirm whether or not the camp-on connection is really made.

Further, as a related technique, Japanese Patent Laid-Open No. 61-19
The technology described in Japanese Patent No. 1156 can be mentioned,
In such a technique, the camp-on registration can be performed by the operation of the caller A by the method described below. That is, when the caller A is informed by another person C who answers the call that the person B who wants to talk is busy, the caller A takes off the hook of his / her own telephone and another person C calls. End the call with. Continuing, caller A
Is to enter the special number for making the camp-on setting and the telephone number of the other party B after checking the dial tone of the own telephone again.

However, this method has a problem that it takes too much time to operate. The present invention was devised in view of such a problem, and even when the dialed partner's telephone is busy and another extension answers, camp-on registration can be performed by a simple operation on the calling side. The purpose is to provide a camp-on control method.

FIG. 1 is a block diagram of the principle of the present invention. In FIG. 1, 1 to 4 are terminals, and these terminals 1 to 4 are connected to an exchange 5. , Which is placed under the control of this exchange 5. Therefore, the terminals 1 to 4 can talk to each other.

Reference numeral 6 is a main controller connected to the exchange 5 and the main memory 7, and the main controller 6 is
It monitors and controls the call status in a call between terminals. That is, for example, the terminals 2 and 4 under the control
When a call between the terminals 2 is completed by performing camp-on registration for the terminal 2 that is in a call with another terminal 4 by an operation from the calling terminal 1 during a call between them, It is controlled so that the connection processing with the terminal 1 on the side is automatically performed (Claim 1).

The main storage device 7 is used to monitor and control a call state in a call between terminals by the main control device 6.
It stores data relating to a call state and the like. In addition, for example, the terminal 1 on the calling side and the terminal 3 currently in communication,
The present invention can be applied to an exchange system configured such that another terminal 4 and a terminal 2 in a call can respond to an incoming call from the terminal 1 on the calling side. There is (claim 2).

[0011]

The operation of the above-described camp-on control system of the present invention will be described with reference to FIG. First, when a call is made from the terminal 1 to the terminal 2 during a call between the terminal 2 and the terminal 4 under the control [see FIG. 2 (a)],
The terminal 3, which can respond similarly to the call to the terminal 2, responds. At this time, the subscriber of the terminal 1 performs a camp-on operation when the subscriber from the terminal 3 is informed that the subscriber of the terminal 2 is busy [see FIG. 2 (b)].

When the camp-on operation is completed, the terminal 1
Ends the call with the terminal 3 and waits until the call with the terminal 4 in communication with the terminal 4 ends (see FIG. 2C). After that, when the call from the terminal 2 to the terminal 4 ends, the exchange 5 under the coordinated control of the main controller 6 and the main memory 7 automatically performs the connection process between the terminals 1 and 2. .

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a block diagram showing an embodiment of the present invention. In FIG. 3, 11, 13, 14 are extension terminals (telephones), and these terminals 11, 13, 14 are connected to an exchange 15. Therefore, it is under the control of the exchange 15.

Numeral 12 is a terminal group having two different terminal numbers, for example, two terminals 12-1 and 12-2 incorporated therein, and each terminal 12-1 and 12-2 forms an extension representative respectively. There is something. Therefore, for example, in response to a call from the terminal 11 to the terminal 12-1, the terminal 12-1
Is communicating with another terminal 14, the terminal 12-2 can respond.

Therefore, the terminals 11, 12-1, 12-2,
13 and 14 can talk to each other. Reference numeral 16 denotes a main control device, which is connected to the exchange 15 and the main storage device 17, and performs line switching control and monitoring control of a call state in a call between terminals. Alternatively, camp-on control is performed.

Here, "camp on" means that the terminal 13 cannot be connected to the terminal 13 even if a call is made from the terminal 11 to the terminal 13 during a call between the terminals 13 and 14. This is a calling side service in which connection processing is automatically performed with the terminal 11 when the call of 13 is completed. That is, for example, when the terminal 11 makes a call to the terminal 13 during a call between the terminals 13 and 14, the caller of the terminal 11 determines from the busy tone that the other party is busy. it can. Therefore, when the call from the terminal 11 on the calling side is completed by performing camp-on registration for the terminal 13 that is in a call with the other terminal 14, the terminal 11 on the calling side is terminated. It is controlled so that the connection process with is automatically performed.

Further, the main storage device 17 stores data and programs for circuit switching, as well as data relating to call state monitoring control or camp-on control by the main control device 16, and is a terminal control memory. Part 17-
1, a call processing data block 17-2, a camp-on registration data section 17-3, and the like. Here, the terminal control memory unit 17-1 includes the subscriber terminals 11, 12-1, 1
By providing areas for 2-2, 13 and 14,
A terminal control memory (not shown) is configured for each terminal. The terminal control memory stores a camp-on registration flag CMPF (not shown) in which information indicating whether or not each terminal has registered camp-on is stored.

The call processing data block 17-2 includes, for example, the terminal 12-1 when the terminal 12-1 is talking with the terminal 13 when the terminal 11 makes a call to the terminal 12-1. The terminal 12-2 forming the extension representative responds, but at this time, the number of the terminal 12-1 is temporarily stored for later camp-on registration. The camp-on registration data unit 17-3 registers the terminal of the calling side and the number of the terminal of the called side regarding the camp-on registration.

The operation of the camp-on control system of the present invention having the above-mentioned configuration will be described below. First, in the flowchart for explaining the operation of the embodiment of the present invention in FIG. 6, when the user of the terminal 11 makes a call to the terminal 12-1 in step S1, the terminal 11 is called in step S2. From the terminal 12-1 number (for example, 11
Dial 12) [see (a) of FIG. 4].

However, the terminal 12-1 on the called side is the terminal 1
4 is busy [see (b) of FIG. 4], step S3
Then, under the control of the main controller 16, the dialed number (1112) dialed by the terminal 11 is stored in the call processing data block 17-2 [see (d) of FIG. 4]. In addition,
At this stage, the camp-on registration has not been registered from any of the terminals, so the terminal control memories 17-11 and 17-12 for the terminal 11 and the terminal 12-1 are both flags indicating camp-on registration OFF. The CMPF is stored [see (c) and (e) of FIG. 4].

Here, the dialed destination terminal 12-1
Is an extension representative, so the terminal 12-
If 2 is vacant, the YES route is taken in step S4, and in the next step S5, a response to the call from the terminal 11 is made by this terminal 12-2, and the state transits to the busy state [Fig. (F)]. Here, the terminal 11
The user is informed that the terminal 12-1 is in use for the first time by a call with the user of the terminal 12-2. Therefore, in step S6, the camp-on registration operation is performed.

That is, the user of the terminal 11 performs hooking and camp-on registration special number dial operation, whereby camp-on registration processing, which will be described later, is performed. That is, when the camp-on registration operation is performed in step S6, main controller 1
Under the control of No. 6, the telephone number (1112) first dialed at the terminal 11 stored in the call processing data block 17-2 is read.

Then, the read telephone number (1112)
Is stored in the camp-on registration data section 17-3 with the telephone number (1111) of the terminal 11 on the side requesting the camp-on registration as an address. [Refer to (g) of FIG. 5].
Further, in step S8, the main controller 16 determines that the terminal 11
Terminal control memory 17-11 and terminal control memory 17-
By turning on the camp-on registration flag in 12, the camp-on registration processing ends (see (h) and (i) in FIG. 5). When the camp-on process ends in step S8, the main controller 16 causes the terminal 12 to
A transition is made to the camp-on monitoring state waiting for the end of the -1 call (step S9).

In step S4, when both the terminal 12-1 and the terminal 12-2 are busy, the terminal 12-1,
When the caller hears a busy tone, such as when a call is made to a terminal other than 12-2, the operation of camp-on registration in step S6 is performed as it is, and thus the processing in steps S7 to S9 is performed. After that, the camp-on monitoring state can be entered.

Thus, for example, the terminals 12-1 and 14
When a call is made from the terminal 11 to the terminal 12-1 during a call between the other terminals, the other extension 12-2 responds, but with a simple operation of the terminal 11 on the calling side, the other terminal 14 is called. The camp-on registration can be performed for the terminal 12-1 during the call, and the call can be surely made with the other party.

Further, since the first dialed number can be stored and the camp-on can be automatically registered in the extension, there is an advantage that the operation can be simplified and erroneous connection can be prevented. . In this embodiment, the terminal 11 is used as the calling terminal and the terminal 12-1 is used as the partner terminal.
However, in the camp-on control system of the present invention, other terminals 13 and 14 are used as the calling side,
It goes without saying that it can be realized by using the terminal 12-2 as the partner terminal.

Further, the present invention can be applied not only to a call between extension terminals but also to a call between a terminal connected via a trunk line and an extension terminal.

[0028]

As described above in detail, according to the camp-on control system of the present invention, in the exchange in which a plurality of terminals are under control, during a call between the terminals under control,
When you perform camp-on registration for a terminal that is in a call with another terminal by operating from the terminal on the calling side, after that,
Since the call state is monitored for the terminal in communication with the other terminal, and when the call of this terminal ends, the connection processing with the terminal on the calling side is automatically performed. There is an advantage that camp-on registration can be performed by a simple operation of the calling terminal.

Further, the calling terminal and the terminal currently in a call and the terminal in a call with another terminal can respond to an incoming call from the calling terminal by any terminal. Since the present invention can be applied to the other party, the camp-on registration can be performed even if a terminal other than the person who wants to make a call responds, and there is an advantage that the person who wants to make a call can surely make a call.
