JPS61127265A - Absence transfer registration system - Google Patents

Abstract

PURPOSE:To make it possible to register an absence transfer service from a transfer destination as well as from a transfer origin by storing calling subscriber's receiving location information and a dialized extension subscriber's location information when a calling-subscriber dials a specific number fixed in advance and successively a subscriber's extension number. CONSTITUTION:When an extension subscriber 1 dials the specific number (for example '11') fixed in advance and successively the extension number of an extension subscriber 2 who is also a destination subscriber its number information is transmitted to a CPU5 through a network (NW)3 and a sending register trunk (ORT)4. By discriminating that the extension subscribers 1, 2 are the origin and destination subscriber respectively by the preceding specific number '11', the CPU5 completes the absence transfer service registration as follows: The extension subscriber receiving location information x0 on the NW3 and the extension subscriber receiving location information y0 on the NW3 are regarded as an origin memory area X, and origin transfer subscriber in a major memory (MM)6 such as an absence transfer service control memory (SCM)60 and the extension subscriber 2 is regarded as the destination subscriber.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a call forwarding registration system.

[Conventional technology]

Conventionally, in this type of automatic switching system, call forwarding registration could only be made from the telephone of the forwarding extension subscriber receiving the call forwarding service.

[Problem that the invention seeks to solve]

In the conventional call forwarding registration method described above, registration can only be made from the forwarding phone, so if a subscriber temporarily moves to another department without registering the call forwarding service from the forwarding phone, Even if a user wishes to have a call forwarded to the extension of his/her department, he or she must return to the original department where the telephone from which the transfer was made is located and register, which is extremely inconvenient.

[Means for solving problems]

The call forwarding registration system of the present invention provides a storage means having a first memory area for storing accommodation location information of a call forwarding subscriber and a second memory area storing accommodation location information of a call forwarding destination subscriber. When a calling subscriber dials a predetermined special number followed by an extension subscriber number, the calling subscriber's accommodation location information and the above are stored in the first and second memory areas, respectively. A control means is provided for storing accommodation location information of a dialed extension subscriber.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of the call forwarding registration system of the present invention. In the figure, the automatic exchange has a network (hereinafter referred to as NW) 3 that accommodates 1.2 tons of extension subscribers, and
Outgoing register trunk (hereinafter referred to as OR) connected to NW3
T) 4, a central control unit (hereinafter referred to as CPU) 5 that performs predetermined sequence control of the automatic exchange, and a main memory (hereinafter referred to as MM) 6t that stores programs and data. MM6 stores multiple call forwarding service control memories (hereinafter referred to as 8
CM) 60.61,62~t-equipped, each 8CM60,6
1゜62, ~ is the first memory area (hereinafter referred to as the transfer source memory area X) that stores the accommodation location information of the absent transfer source subscriber.
and a second memory area (hereinafter referred to as transfer destination memory area Y) that stores the accommodation location information of the absent transfer destination subscriber.

Next, the operation of this embodiment will be explained.

When extension subscriber 1 dials the extension number of extension subscriber 2, which is the transfer destination subscriber, after dialing a special number (for example, "11") predetermined as the transfer source subscriber, the number information [NW3,0RT4t-via The CPO 5 determines that extension subscribers 1 and 2 are the transfer source subscriber and transfer destination subscriber, respectively, based on the special number 111'', and determines the accommodation location of extension subscriber 1 on the NWa. Information x□, accommodation location information on NWX of extension subscriber 2 yo f
: Stored in the transfer source memory area finish.

Conventional automatic switching machines only allow the above-mentioned registration method.

In this embodiment, when extension subscriber 1, who has performed the above registration, temporarily moves to another department (for example, the department of extension subscriber 2), the phone of the original department is transferred from the telephone of extension subscriber 20 to the transfer destination. You can change the registration of the call forwarding service with the other person. In other words, extension subscriber 2 uses a predetermined special number (e.g. @12'') different from the special number 111' as a transfer source subscriber, and then an extension subscriber who is a new transfer destination subscriber (e.g. extension subscriber). When the extension number of subscriber 1) is dialed, the number information is transmitted to the CPU 5 as is generally known.The CPU 5 uses the special number 112# to dial the extension number of subscriber 2).
．． 1 are the transfer source subscriber and transfer destination subscriber, respectively, and transfer the extensions 2 and 1 to each other using a generally known method.
Accommodation position information y on NWa. * ”Ot- Stored in the transfer source memory area
xO, and extension subscriber 2 is the forwarding subscriber and extension subscriber 1 is the forwarding destination subscriber. The call forwarding service registration is completed.

In addition, when an extension subscriber (not shown) other than extension subscriber 1.2 registers for call forwarding service or changes registration,
8CM61,62. . . . etc. are used and the operation is similar, so the explanation will be omitted. Also, if the special number dialed by the calling subscriber is predetermined, it will be "11" or "1".
It is not limited to 2'.

〔Effect of the invention〕

As explained above, the present invention enables registration of call forwarding service not only from all forwarding sources but also from forwarding destinations, thereby reducing the troublesome operation of registering call forwarding, thereby improving convenience. This also has the effect of improving services.

Claims (1)

[Claims] In an automatic exchange equipped with a storage means having a first memory area for storing accommodation location information of a call forwarding subscriber and a second memory area for storing accommodation location information of a call transfer destination subscriber, the calling subscriber When dialing a predetermined special number followed by an extension subscriber number, the first and second memory areas store, respectively, the accommodation location information of the calling subscriber and the accommodation location information of the dialed extension subscriber. 1.
