Abstract

PURPOSE:To select a transferred party replying with a telephone set of a transfer destination by the user of absence transfer service by providing a registering means for transfer destination information and transferred information to apply transfer, and a storage means for transfer sender and transfer destination extension information, CONSTITUTION:When an extension A uses the transferred party selection system of the absence transfer service, first a special operation stating the use of the service is conducted. For example, an extension B is registered as the absence transfer destination number and the number of an extension X is registered as the transferred party. Thus, a CPU 2 recognizes the special operation via a switch frame SW1, stores the information of the extension A being the transfer sender and the information of the transferred extension B in an absence transfer memory 4 in the storage device 3, the information of the extension X is stored in a transferred party information memory 5 to complete the registration processing. When a call comes to the extension A, the CPU 2 identifies it and compares it with the information of the extension X in the memory 5, and when the incoming call is addressed to the extension X, it is connected to the extension B being the transfer destination and not connected to other extensions. Thus, the telephone set of the transfer destination can select the transferred party to be replied.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for selecting a forwarded party in a call forwarding service.

[Conventional technology]

In conventional automatic switching systems having a call forwarding service function, there is no means for selecting a forwarded party to whom calls are to be forwarded, and all incoming calls to a forwarding source are connected to a registered forwarding destination.

[Problem that the invention seeks to solve]

In the conventional call forwarding service described above, the incoming call to the forwarding source is unconditionally connected to the registered forwarding destination, regardless of the intention of the extension subscriber using the call forwarding service. A disadvantage is that it is not possible for the extension subscriber using the service to select the transferred party who will answer on the transferred telephone.

[Means for solving problems]

The forwarded party selection method in the call forwarding service of the present invention includes a means for registering forwarding destination information and forwarded party information to be forwarded by a special operation from an extension subscriber's telephone who intends to use the call forwarding service; a storage means for storing source extension information, forwarding destination extension information, and information of the forwarded party to whom the transfer is to be made; and when an incoming call is received to the registered forwarding source, the incoming call information is identified and the connection is made to the forwarding destination. control means for controlling whether to connect or not to connect.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a memory configuration diagram showing an example of the storage device in FIG. 1.

As shown in Figure 1, the automatic exchange has extensions A and B.

~Switch frame that accommodates X, Y, and Z (hereinafter referred to as 5W)
1, a central processing unit (hereinafter referred to as CPU) 2 which is connected to the SWI and controls all sequence control within the automatic exchange;
It is configured to include a storage device (hereinafter referred to as MEM) 3 that stores programs executed by U2 and various data.

As shown in FIG. 2, the MEM 3 includes a missed transfer memory 4 and a transferred person information memory 5. The absent transfer memory 4 stores the extension information of the transfer source and the transfer destination, and the transferred person information memory 5 stores the extension information of the transferred person.

Note that the extension information includes data such as each extension number, extension group number, and extension class.

Next, the operation of this embodiment will be explained.

When extension A performs a special operation to use the forwarding party selection method of the call forwarding service, for example, registers extension B as the call forwarding destination number and registers the number of extension X as the forwarding party, the CPU 2 recognizes this special operation from extension A via SWl. The CPU 2 stores information on the extension A of the transfer source and extension B of the transfer destination in the missed transfer memory 4 in the MEMB, and stores information on the extension X in the transferred party information memory, and ends the registration process.

After that, when a call arrives at extension A that was registered as the transfer source,
The CPU 2 identifies the extension information of this incoming call using a generally known method and compares it with the information on the extension X read out from the transferred party information memory 5. Here, if the incoming call is extension X, it is connected to extension B, which is the transfer destination. In addition, if extension Y or extension Z is not registered as the transferred party, CP
U2 controls not to connect to extension B.

Next, when canceling this forwarded person selection, when a special operation is performed from extension A or extension B, the CPU 2 clears the stored contents of the forwarded person information memory 5 in the MEM 5, and the conventional missed call forwarding service will be carried out. Note that the conventional call forwarding service can be canceled using a well-known technique.

〔Effect of the invention〕

As explained above, the present invention allows the user of the call forwarding service to select the forwarded party who answers on the forwarding destination telephone by registering the extension information of the forwarding destination and the forwarded party information in the call forwarding service. This has the effect of making it possible.
