Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer system to a picked-up subscriber in a digital exchange which provides a pick-up service.

[0002] The pickup service has the convenience that other subscribers can respond to incoming calls from outside lines by proxy if they are in the same group as the subscribers to be picked up. Transfer was inconvenient.

In the pickup service, a subscriber who is generally called a called subscriber is often referred to as a called subscriber.

[0004]

2. Description of the Related Art Conventionally, there is an exchange that provides a function of answering an incoming call from an outside line to any one extension within the pickup group by another extension telephone within the same pickup group. Is called.

The conventional pickup service technology will be described below. Figure 3 shows this conventional pickup
It is a block diagram showing the basic composition of the exchange which provides a service.

In the figure, 1 is a switch, and 2 is a speech path network, 3 is a central controller, and 4 is a main memory. The main storage device 4 stores a program required for a normal exchange connection and a program for providing a pickup service. The central control unit 3 reads the program and executes the switching connection and also executes the pickup service.

For example, when the telephone of the telephone of the subscriber A who has left the desk is ringing, another extension telephone B in the pickup group to which the subscriber A belongs is sent to the main storage device 4, for example. By sending the registered special number only for the response, B can make a proxy response under the control of the central control unit 3, which is convenient.

[0008]

However, for example, it is assumed that the picked-up subscriber A in the pickup group happens to be absent and another subscriber B makes a proxy response. Here, if A is allowed to return, naturally B is transferred to A. The transfer operation differs depending on the exchange, but is generally complicated. In addition, conventionally, at least the telephone number of the transfer destination A necessary for the transfer has to be stored or checked by the proxy response subscriber B himself.

It is an object of the present invention that the proxy answer operation of the subscribers in the same pickup group different from the picked-up subscriber is extremely easy, but the transfer from the proxy answering subscriber to the picked-up subscriber is performed. Eliminates the disadvantages of traditional pickup service technology, which is inconvenient, including the need for proxy answering subscribers to remember, look up, or otherwise retrieve the telephone number of the called subscriber. The point is to provide a transfer system to a picked-up subscriber in a digital exchange which is easy to operate.

[0010]

FIG. 1 shows the principle of the present invention. In the figure, a block 3 indicated by a broken line and a block 4 indicated by a broken line respectively correspond to a speech path network, a central control unit and a main memory unit in a digital exchange. In the central controller 3, 31 is a communication path setting control means, 32 is a first control means, and 33 is a second control means. In the main memory 4, 41 is a pickup target subscriber list storage sub-area, and 42 is a telephone number copy sub-area of the picked-up subscriber.

As shown in FIG. 1, when an absent picked-up subscriber is called through the call-path network 2 under the control of the call-path setting control means 31, the pick-up subscriber to which the picked-up subscriber belongs In a digital exchange that provides pickup service in which other subscribers in the group send proxy response information to respond to an incoming call to the pickup target subscriber, a pickup target subscriber list storage sub-area 41 of the main storage device 4 is provided. A telephone number copy sub-area 42 of the picked-up subscriber and the proxy response information received from the call path setting control means 31 to the picked-up subscriber via the call path network 2. And release of the call path, and the sending subscriber and the proxy response information sending subscription through the call path network 2 The first control means 32 for causing the call path setting control means 31 to set up a call path between and the copy of the telephone number of the picked-up subscriber to the telephone number copy sub-area 42. And when the call path setting control means 31 receives the transfer control information from the proxy reply subscriber, the transfer path control means 31 controls the call path setting control means 31 to read the transfer control from the telephone number copy sub-area 42. Second control means 33 is provided for setting the speech path between the information-captured subscriber and the calling subscriber in the speech path network 2.

[0012]

In FIG. 1 showing the principle of the present invention, a subscriber A to be picked up through the call path network 2 from a caller of an outside line accommodated in the call path network 2 under the control of the call path setting control means 31. Suppose there is a call. When the subscriber A is absent, when the other subscriber B in the same pickup group sends the proxy response information, the first control means 32 transmits the proxy response information to the subscriber to be picked up via the communication path network 2. The formed communication path is released, and the communication path setting control means 31 is driven to set the communication path between the calling subscriber and the proxy response subscriber via the communication path network 2. At the same time, the first control means 31 causes the telephone number of the picked-up subscriber to be copied to the telephone number copy subarea 42.

Here, it is assumed that since the picked-up subscriber A acknowledges that he / she is returning, the proxy response subscriber B sends the transfer control information. The call path setting control means 31 uses the proxy response subscriber B
When the transfer control information is received from the second control means 33, the second control means 33 controls the call path setting control means 31 to set the call path between the picked-up subscriber A and the calling subscriber to the call path network 2. Let it set. In this case, the telephone number of the subscriber A to be picked up is included in the transfer control information.

EXAMPLES Examples of the present invention will be described below. FIG. 2 shows an arrangement example of the storage areas according to the present invention.

In the figure, reference numeral 5 denotes a storage area in the main storage device according to the present invention. In addition, the pickup target subscriber list storage sub-area 41 stores the names of all subscribers in the same group who receive the pickup service and their telephone numbers. Further, the call processing work memory 43 of the answering subscriber stores a program necessary for transferring from the proxy answering subscriber to the picked-up subscriber. In this,
It includes a telephone number copy sub-area 42 of the picked-up subscriber.

In FIG. 2, the shape dimensions such as a rectangle are not necessarily strict, and the positional relationship is schematically shown. Next, the flow of transfer in the digital exchange in which the pickup service function is built will be specifically described.

FIG. 3 is a transfer flow chart. The program for executing this flow chart is stored in the main memory 4 of the digital exchange. The order of the flow in the following description corresponds to the number of each block shown in FIG.

In the figure, first, 10, the flow of transfer is started,
11. When an external line receives a call from one subscriber A in the group receiving the pickup service, the telephone number A is selected from the "pickup target subscriber list storage sub-area" 41.

13. Just because A is absent and hears the bell of the telephone ringing, another subscriber B in the same group answers, so dial a special number for replying, for example, 00. ..

14, then B responds. 15. The telephone number of A is copied to the "phone number copy sub-area of picked-up subscriber" 42 in the "call processing work memory of the answering subscriber" 43.

16. Here, since it is acknowledged that A has returned, 17, B hooks once, and 18, continues,
When B sends a special number for transfer, for example, 3377,
19. In the "call processing work memory of the answering subscriber", the special number is discriminated, and the transfer from B to A is performed according to the program stored therein, 20, and the transfer flow ends.
