Abstract

PURPOSE:To efficiently use a line by identifying useless lines out of lines set to connect between exchanges and cutting off the useless lines and reconstituting connecting lines cutting off the useless lines. CONSTITUTION:When a telephone set 32 makes specified procedure for transfer to transfer a call to a telephone set 33 when a telephone set 31 of a caller is speaking with the telephone set 32 through exchanges 41, 42, the telephone set 31 is suspended and connected to the telephone set 33. At this time, the exchange 42 identifies whether the objective of connection of a transferring line (b) formed when transfer connection is made is the same with the exchange 41 to which a line (a) suspended from the telephone set 32 that requested transfer or not, and when it is identified that it is a connection route to the same exchange 41, the set lines are judged as useless lines, and the useless lines (a), (b) are cut off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a line configuration system for a communication network that employs a common line signaling system.

[Conventional technology]

In the conventional line configuration method, in the case of reconnection by transfer, the exchange reconfigures the line by transfer regardless of the line configuration initially connected within the communication network.

A conventional example will be explained with reference to FIG. Figure 4 (A)
4(B) is a line configuration diagram showing an example of the case where the called party calls the forwarding destination, and FIG. 4(B) shows the state in which the called party communicates with the forwarding destination in FIG. 4(A), confirms the transfer, and then leaves the communication line. FIG.

In FIG. 4(A), a caller first calls a telephone 32 connected to an exchange 92 from a telephone 31 via an exchange 91, and creates a line m via a line a. telephone 32
In order to connect to the telephone set 33 where the called party is located, the caller puts line a, which is the incoming line, on hold and calls exchange a193. The line route from the exchange 92 to the exchange 93 consists of an exchange via the exchange 91, a line B from the exchange 192 to the exchange 91, and a line C from the exchange 91 to the exchange 93.The telephone 32 connects to the telephone 33. When the transfer is confirmed and the transfer is notified, the handset is on-hook and the connection is established, the connected line configuration remains unchanged and the switch 92
Line a and line A are directly coupled within the same line.

[Problem that the invention seeks to solve]

In the conventional line configuration method described above, the exchange is configured in such a way that the line that was first connected and the line that was then connected for transfer to the called party remain directly connected. There was a problem in that the lines were inefficiently used, such as the lines being used to go back and forth between exchanges.

An object of the present invention is to provide a line configuration system that solves the above problems.

[Means for solving problems]

The line configuration method of the present invention is a line configuration method for a communication network that is configured with at least two exchanges and employs a common line signaling system, and identifies unused lines among the lines that are set up for connection between exchanges, and provides information on the unused lines. an identification means for outputting the unused line information, a sending means for transmitting the unused line information to an exchange to which the unused line is connected, and a transmitting means for disconnecting the wireless line and reconnecting the connected line when the unused line information is received on the originating side of the unused line. The exchange has reconfiguration means for configuring.

Another specific means includes an identification means for, when an exchange returns one call and sets a round-trip line, the connected exchange identifies the same round-trip line as a useless line and outputs useless line information. have

〔Example〕

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

1 and 2 are flowcharts showing an example of the main operating procedures of an exchange according to an embodiment of the present invention, and FIG. 3 (A
) is a line configuration diagram showing an example of a case where the receiving telephone calls the forwarding destination, and FIG. 3(B) shows a line configuration diagram showing an example of a case where the receiving telephone calls the forwarding destination in FIG. FIG. 3 is a line configuration diagram showing the state.

The present invention will be described with reference to FIGS. 1 and 2 together with FIG. 3. The operation procedure 2 in FIG. 1 causes the identification means 2 to
The operating steps 3 each form a delivery means 3. Further, the operating procedures 22 and 23 in FIG. 2 form the reconfiguration means 20. In FIG. 3, the calling party makes a call from the telephone 31, activates the exchange 41, and first receives the call to the telephone 32 of the exchange 42.
This telephone f7132 is transferred to the telephone 33 of the exchange 43 and connected to the called party.

In FIG. 1, the connection request for the set line (operation procedure 1) is made in FIG. To the forwarding destination phone number 33,
Exchange 421 line.

Exchange 411 is connected via line C1 exchange 43.

The exchange 42 determines whether the connection destination of the transfer line A formed at the time of transfer connection is the same as or different from the exchange 41 to which the hold line a placed on hold from the telephone 32 that requested the transfer is connected.
When it is determined that the connection route is to the same exchange 41, the set line is determined to be a useless line (operation procedure 2). When the exchange 42 determines that an unused line has been set, it sends out unused line information including the line numbers of at least two unused lines to the connected exchange 41 using the sending means 3 using the common line signaling method (operation procedure 3).

In this line configuration state, the telephone 32 confirms the incoming telephone 33 and notifies the transfer, and then goes on-hook, so the exchange 42 receives a disconnection instruction and notifies the exchange fi 41 of the disconnection of the unused line. a and disconnects the unnecessary line If (operation procedure 4). On the other hand, moving cattle procedure 2
When the connection destinations do not match and the set line is valid, the exchange 42 connects the line a and the line p (not shown) whose connection destination is other than the exchange 41 to combine the set lines (operation step 5).
t End the procedure.

The exchange 41 receives useless line information including wireless lines a-b (operation procedure 21), and then, when not receiving a disconnection instruction, disconnects the unnecessary line a to the exchange 42 and disconnects the unnecessary line from the exchange 42. At the same time as disconnecting (operation procedure 22), the line C that was connected to the unused line A is connected to the telephone 31 that was connected to the unused line A. Therefore, the exchange 41 connects the communication path from the telephone 31 to the telephone 33 via the exchange 411 line C1 exchange 43 to form a reconfigured line (
It has a reconfiguration means 20 for performing the operation 1\procedure 23).

In the above embodiment, the identification means, sending means, and reconfiguration means were explained using program procedures, but they can also be implemented using known hardware. The identification means identified useless lines by checking that the line set for connection to the forwarding destination was the same as the exchange to which the line set on the calling side was connected, but it was simply because the line set for the forwarding destination was relayed to the local exchange. The line may be identified as a useless line. In this case, the sending means is required to send the dialing code of the transfer destination to the calling side exchange using the common channel signaling system. If the forwarding destination dialing code is transmitted using the common line signaling method, the disconnection of the unused line may be performed before the transmission of the dialing code included in the unused line information. By setting this in advance, it is possible to realize a line reconfiguration method that allows efficient use of the lines between exchanges without requiring only transfer as a condition.

〔Effect of the invention〕

As explained above, the line configuration method of the present invention has the effect of making it possible to use lines more efficiently by finding unnecessary lines that are being used more than necessary and reconfiguring them to a line state that reduces the number of unnecessary lines. .
