Abstract

PURPOSE:To decentralize calls in a business group wherein bases are decentralized so that they are at the same base by registering a multiline hunting group as a subscriber group which is connected to not only subscribers of one office, but also plural offices. CONSTITUTION:An office which includes a called subscriber is decided (step 1). When the called subscriber is included in another office, an inquiry signal inquiring whether the subscriber is free or engaged to the latter office from a calling-side office through a common line signal link (step 2). An answer to the inquiry signal is received as an answer signal through the common line signal link (step 3). The state of the subscriber is confirmed (step 4) and when the subscriber is free, an outgoing connection with the subscriber is made (step 5). When the subscriber is engaged, on the other hand, the number of a next subscriber in a multiline hunt list is obtained (step 6) and its free decision is made similarly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-line hunt system in a storage program control type exchange.

[0002]

2. Description of the Related Art In the conventional multi-line hunt system, all subscribers of one group forming the same multi-line hunt group must be accommodated in one station, and a designated subscriber in the same group is busy. If it is closed with, it is configured to select another free subscriber in the same group.

[0003]

In the conventional multi-line hunt system, it is necessary to know the availability / blockage of the subscribers of the multi-line hunt group, but a group of subscribers accommodated in one station can be formed. , There was no way to know the vacancy / blockage of subscribers accommodated in other stations, so it was not possible to form a multi-line hunt group that spans multiple stations.

[0004]

The multi-line hunt system of the present invention is a multi-line hunt system in a storage program control type exchange, and a plurality of multi-line hunt groups housed in the same station and other stations to form the same multi-line hunt group are accommodated. When a called subscriber is judged to be accommodated in another station when it is determined that the called subscriber is available, it is equipped with a storage unit for registering the subscriber. An inquiry signal for inquiring about the vacancy / occlusion of the corresponding subscriber is transmitted to the other station via the signal link, and the station on the receiving side receives the inquiry signal and confirms the vacancy / occlusion of the specified corresponding subscriber. Check the result, set the result as a response signal, and send it back to the originating station via a common line signal link. The originating station receives the response signal, and if the corresponding subscriber is idle, the other station Applicable subscriber of Performed out of the connection, a configuration in which it proceeds to determine the free state of the next subscriber registered in the storage unit if was Tsu.

The present invention will be described below with reference to the drawings.

FIG. 1 is a flowchart showing a destination subscriber determination process for an incoming call to a subscriber in a multi-line hunt group according to an embodiment of the present invention. FIG. 2 is a diagram showing a connection concept for explaining an embodiment of the present invention. Subscriber A, subscriber B, subscriber C and exchange β accommodated by exchange α.
The subscribers D and E who are accommodated form the same multi-line hunt group, and the exchanges α and β are the interoffice line F and the common line signaling system NO. 7 Link G is connected. FIG. 3 is a diagram showing an example of the multi-line hunt subscriber list, in which subscribers of the exchange α and the exchange β are mixed. FIG. 4 is a diagram showing an inter-station signal sequence when a call to the subscriber C accommodated in the exchange α shown in FIG. 2 occurs when the subscriber C is busy and slips the call to the subscriber D. is there.

The operation will be described below.

The exchange α seeks a subscriber D next to the subscriber C from the multi-line hunt subscriber list shown in FIG. Since the subscriber D is a subscriber accommodated in another station (step 1), in the exchange α, the information for inquiring about the vacancy of the subscriber D is set on the vacancy inquiry signal, and the common line signaling method NO. 7 Send to other station via link G (step 2). Upon receipt of this, the exchange β checks the status of the subscriber D, sets the vacancy / blockage information on the status response signal, and sets the common line signaling system NO. 7
Return to switch α using link G. The exchange α receives this information (step 3), determines the state of the subscriber D (step 4), and if the subscriber D is free, transfers the incoming call request to the subscriber C to the exchange β. The connection process is activated (step 5). If it is closed, the step of calling the next subscriber E is performed (step 6).

First, an incoming call arrives at subscriber B,
The operation when the subscriber B is talking and slips to the subscriber C is as follows. In step 1, the subscriber C is determined to be a subscriber accommodated in its own station, and when it is determined in step 8 that the state of the subscriber C is empty, the incoming call connection process for connecting the incoming call to the subscriber C (step 9) To start.

[0010]

As described above, according to the present invention, the availability / blockage of the subscribers who form the same multi-line hunt group accommodated in another station is known through the common line signal link. The line hunt group can be registered not only as a subscriber of one station but also as a subscriber group that is accommodated by multiple stations, and slips between subscribers are also possible, so that it is possible for business groups with dispersed bases to be in the same location. The effect is that calls can be distributed.

Claims (1)

[Claims] 1. A multi-line hunt system in a storage program control type exchange, comprising a storage unit for registering a plurality of subscribers accommodated in its own station and other stations and forming the same man-lunch line hunt group, When it is determined that the calling subscriber is accommodated in another station when determining the availability of the calling subscriber, the calling station sends the other subscriber to the other station via a common line signal link. / Sends an inquiry signal to inquire about the blockage, and the receiving station receives this inquiry signal, checks the vacancy / blockage of the specified specified subscriber, sets this result as the response signal, and sets it as the common line. It returns to the originating station via a signal link, and the originating station receives the response signal, and if the corresponding subscriber is idle, makes an outgoing connection to the corresponding subscriber of the other station and closes it. If it was, register it in the storage section The multi-line hunt system characterized by shifting to the determination of the idle state of the next subscriber who has been made.
