Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for connecting a subscriber to another line established by a predetermined procedure when a subscriber is absent at a terminal of a line connected to an exchange. This invention relates to a variable call forwarding method for connecting incoming calls after setting to a setting terminal.

[Conventional technology]

The conventional variable call forwarding system includes a service setting registration means for registering information on accommodation lines connected to an exchange and information on services set for each accommodation line, and a service information registration area of this service setting registration means. The system is provided with a transfer destination information registration means for registering, for each registered line, information on the transfer destination line in the absence transmitted from the set line at the time of setting registration, for each registered line.

When a terminal sets a variable call forwarding service using a variable call forwarding setting code and a forwarding destination code, the service setting registration means registers the variable call forwarding setting in the service area of the accommodation line that transmitted the setting code, and The information registration means registers the registered accommodation line as a registered line and also registers the received forwarding destination code in the forwarding destination area of this registered line.

When there is an incoming call on the registered line, the connection control means of the exchange indexes the setting information of variable absentee forwarding from the service area of the destination accommodation line of the service setting registration means, so it calls the forwarding destination information registration means and performs the corresponding registration. The forwarding destination information is indexed from the forwarding destination area of the line, and then the indexed forwarding destination is connected to the originating line of the incoming call.

[Problem that the invention seeks to solve]

As mentioned above, the conventional variable call forwarding system is configured so that only the registered line that requests the registration of settings for variable call forwarding registers forwarding destination information in the forwarding destination information registration means.
For example, when a workplace is forming a group and all employees hold a meeting in a conference room, there is an operational service shortage that requires setting variable call forwarding from all terminals deployed in the group using the same operation. There was a problem with exclusion.

[Means for solving problems]

The variable call forwarding system of the present invention includes a main switch that accommodates an accommodation line that connects a terminal, a connection control means that mainly controls the connection of this switch, and a forwarding destination line index that indexes the forwarding destination line when an incoming call is received. a forwarding destination setting means for setting a forwarding destination when an incoming call is received while the user is absent; a service setting registration means for storing and registering a service set for each accommodation record; and a registered line registered in the service setting registration means. A forwarding destination information registration means for registering forwarding destination information for each line group, a plurality of accommodation lines forming a line group as a group line and a group line, and one accommodation line among the group line lines as a representative line. , and a line group registration means for pre-registering each line group.

When setting up the group variable call forwarding service, the forwarding destination setting means receives the information of the originating accommodation line, the group variable call forwarding code and the forwarding destination code received from the terminal via the connection control means, and first registers the line group. call the means. The transfer destination setting means searches for the accommodated line that transmitted the group variable absent transfer code from among the registered group registered lines, indexes the representative line of the line group including this accommodated line as a registered line, and sets the transfer destination together with the forwarding destination code. While registering in the information registration means, the group variable absent transfer setting is registered in the service area of the service setting registration means for all accommodated lines included in the line group indexed by the representative line.

When a call arrives at the accommodation line for which the group variable call forwarding service has been set, the transfer destination line indexing means obtains information from the service setting registration means and calls the line group registration means. The transfer destination line indexing means indexes the representative line of the line group including the called receiving line from among the group registered lines of the line group registration means, and sends the transfer destination information with this representative line as the registered line from the transfer destination information registration means. Index to get the destination line.

Although a registration area for a representative line is provided in the line group registration means, if a representative line is not provided, all accommodated lines registered as a line group can be registered in the registered lines of the forwarding destination information registration means. Search and index procedures in the line group registration means can be deleted from the transfer destination line index operation procedure.

activates the transfer destination setting means 15 using the group variable absence transfer setting code taken out from the code receiving means 121. The activated transfer destination setting means 15 calls the line group registration means 19 and uses the call accommodation line as a key to search for a representative line of the line group including the call accommodation line (operation step 4). Next, the transfer destination setting means 15
calls the forwarding destination information registration means 18 and searches for 1 representative line among the registered lines (operation step 5), and if the representative line is not included (
Operation procedure 6) Confirm that call forwarding is not set.

The connection control means 13, which has confirmed that it has not been set in operation step 6, causes the code reception means 121 to erase the stored information and return to the initial state, and at the same time causes the signal transmission means 122 to notify the completion of preparation for receiving the transfer destination code. It is connected to the transmission path to the calling terminal via the switch 11, and preparations for receiving the transfer destination code are completed (operation step 7). Next, when the code receiving means 121 receives the transfer destination code transmitted by the calling terminal (operation procedure 8), the connection control means 13 disconnects the connection with the main switch 11 and stops the signal sending means 122 from sending out the signal. Connection control means 1

1, and also connects the transmission path to the signal sending means 122 for transmitting the preparation for reception completion to notify the completion of preparation for reception of the code (operation procedure 22). Next, when the code receiving means 121 receives the called party code via the incoming call accommodation line (operation procedure 23), the connection control means 13 converts the received called party code by the called party code converting means 14 and converts the received called party code into information. Whenever the information on the call accommodation line is retrieved (operation step 24), the signal sending means 122 is disconnected and signal sending is stopped. The connection control means 13 first calls the service setting registration means 17 and searches for a set service using the called accommodation line taken out from the called party code conversion means 14 as a key (operation step 25).

First, when detecting the setting of group variable missed forwarding (operation procedure 26), the connection control means 13 activates the forwarding destination line indexing means 6 to call the line group registration means 19, and the forwarding destination line indexing means 16 calls the called line group registration means 19. Index the representative line of the line group including the accommodated line (
Operation procedure 27). Next, the transfer destination line indexing means 16 calls the transfer destination information registration means 18, searches for registered lines using the indexed representative line as a key, and indexes the transfer destination information (operation step 28).
)do. The indexed forwarding destination information is sent to the connection control means I3, and the connection control means 13 connects the incoming call accommodating line to the called accommodating line obtained from the forwarding destination information via the main switch 11 (
The transfer operation procedure ends with operation step 29).

Also, the setting of independent variable call forwarding is detected (operation procedure 31
), the connection control means 13 causes the transfer destination line indexing means 16 to search the registered line using the called accommodation line as a key and index the transfer destination information (operation step 32), and then continues to the aforementioned operation step 29 ( .

On the other hand, when no service is set in operation step 25, the connection control means 13 connects the incoming call accommodating line to the called accommodating line taken out in operation step 24 via the main switch 11 (operation step 4).

In the transfer destination information area 280, transfer destinations M and LN are registered for all accommodation lines A-B and CD, for which the settings for absent transfer have been registered. In the line group area 290, accommodated lines A-C... and accommodated lines E-F...
- form each line group, but there is no representative line. If the line group does not have a representative line in this way, when registering service settings, the forwarding destination information registration means registers all registered lines included in the registered line group in the forwarding destination information area along with the same forwarding destination information. However, when an incoming call is received on the accommodated line for which service settings have been registered, the forwarding destination information can be directly indexed from the forwarding destination information area without searching the line group area.

In the above embodiment, the main operating procedures are illustrated in FIGS. 4 and 5, but there are procedures that can perform the same function as described above even if the series operating procedures are parallel or the front and back of the operating procedures are switched, so only one figure is shown. The steps taken are not intended to limit the invention.

〔Effect of the invention〕

As explained above, the variable missed forwarding system of the present invention includes a line group registration means for registering a plurality of accommodated lines forming a group as one line group, and a forwarding destination setting means for registering accommodated lines included in the same line group. By providing a group variable absence setting code and a transfer destination code that are retrieved and the forwarding destination is registered, a terminal connected to one accommodated line included in the same line group can transmit the group variable absence setting code and the forwarding destination code to This shows the effect of improving operational service by providing the same forwarding destination for all of the accommodation lines.
