Description

[Detailed Description of the Invention] [Summary] The present invention relates to a transfer method in an exchange, particularly an interrupt transfer method that simplifies the transfer operation of a transfer source subscriber, and simplifies the operations required for transfer by a transfer source subscriber as much as possible. For the purpose of this, an interrupt transfer group is formed by multiple subscribers accommodated in an exchange, and interrupt transfer group configuration information indicating the configuration of the interrupt transfer group by each subscriber and the call status of each subscriber is stored. an interruption transfer table including call status information indicating that the transfer destination subscriber wishes to make a call to the other party subscriber in place of the transfer source subscriber who is in the call state; When information specifying a subscriber is received, it refers to the interrupt transfer table, identifies whether or not the transfer source subscriber and transfer destination subscriber belong to the same interrupt transfer group, and determines whether or not the transfer source subscriber and the transfer destination subscriber belong to the same interrupt transfer group. If it is determined that the subscriber and the transfer destination subscriber belong to the same interrupt transfer group, the transfer destination subscriber is called on behalf of the transfer source subscriber after confirming that the transfer source subscriber is in a call state. An interrupt transfer means for establishing a conversation with the other subscriber is configured to be provided in the exchange.

[Industrial application field]

The present invention relates to a transfer method in an exchange, and particularly to an interrupt transfer method that simplifies the transfer operation of a transfer source subscriber.

As one of the functions of switching equipment, a callback/transfer function or a call park function, which transfers a call in progress to another subscriber, is widely adopted.

In this type of transfer function, it is desired that the operations required for transfer by the transfer source subscriber be as simple as possible.

[Conventional technology]

FIG. 4 is a diagram showing an example of a conventional callback transfer method.

In FIG. 4, it is assumed that subscribers 2a and 2b accommodated in exchange 1 are in a conversation state via communication path pl set within network (NW) 11. In FIG.

In this state, subscriber 2. (hereinafter referred to as transfer source subscriber 2b) transfers to the other subscriber 2. (Hereafter, callee subscriber 2.
If you wish to transfer a call to another subscriber 2c (hereinafter referred to as forwarding destination subscriber 2c) accommodated in exchange 1, you need to transfer the call to another subscriber 2c accommodated in exchange 1 (hereinafter referred to as transfer destination subscriber 2c). After performing the operation, dial the telephone number Nc given to the transfer destination subscriber 2c.

Transferring subscriber 2. The central control unit (CC) 12 that detected the hooking operation activates the callback transfer control unit (CBTF) 12a, selects and calls the transfer destination subscriber 2c, and when the transfer destination subscriber 2e responds, the network ( NW) 11, and transfer source subscriber 2. During the connection, the other subscriber 2. When the transfer source subscriber 2b, who informed the transfer destination subscriber 2c of the transfer, recovers, it sets up a communication path p in the network (NW) 11 and connects the transfer destination subscriber 2a with the transfer destination subscriber 2a. The user 2e is placed in a conversation state.

Next, FIG. 5 is a diagram showing an example of a conventional call park system.

In FIG. 5, a transfer source subscriber 2. If the user wishes to transfer the call with the subscriber 2a to the other subscriber 2d accommodated in the exchange 1 (hereinafter referred to as the transferee subscriber 2d), the transfer request is transmitted to the exchange 1. After performing a hooking operation to perform a call park request, the user dials a special hold number determined for a call park request and a hold number for distinguishing between calls that are requesting a call park, and then restores the call.

The central controller (CG) 12 detects the hooking operation of the transfer source subscriber 2b and the hold special number, activates the call park control unit (CPK) 122, associates the call destination subscriber 2a with the hold number, and places the callee on hold. state.

On the other hand, the transfer source subscriber 2. Subscriber 2 on hold from
．． Transfer destination subscriber 2d, who was requested to respond to the call and was informed of the hold number, makes a call, and receives the response special number determined for the call park response and the transfer source subscriber 2. When you dial the hold number given to you by the call park controller (CP),
K) 122 identifies the subscriber 2a on hold based on the hold number and transfers the call to the subscriber 2. Then, a call is established via the call path p4 set within the network (NW) 11.

[Problem to be solved by the invention]

As is clear from the above explanation, conventional callbacks and
In the transfer method, the transfer source subscriber 2b requires a hooking operation and a dialing operation of the telephone number Nc of the transfer destination subscriber 2C as a transfer operation, and in the conventional call park method, the transfer source subscriber 2. Since the transfer operation requires a hooking operation and a dialing operation of a reserved special number and a reserved number, not only does the transfer time take longer, but there is also the risk that the transfer may end in failure due to an incorrect operation.

An object of the present invention is to simplify as much as possible the operations required for transfer by a transfer source subscriber.

[Means to solve the problem]

T) 131, and an interrupt transfer control section (ITF) 123 is provided in the central controller (CG) 12 as the interrupt transfer means 300 in FIG.

The group index G is set to logic "1" if the corresponding subscriber 2 belongs to the interrupt forwarding loop, and is set to logic "O" if the subscriber 2 does not belong to the interrupt forwarding loop.

Further, the next telephone number Ni indicates the telephone number of the subscriber 2 to be connected next when the subscribers 2 belonging to the same interrupt transfer group are connected in a chain.

Furthermore, the status information S is set to logic "1" if the corresponding subscriber 2 is in a talking state, and is set to logic "0" if the subscriber 2 is in a state other than talking.
” is set.

In FIG. 2, telephone numbers Nb and N are shown, respectively. and N, subscriber 2b, 2. and 2. constitute one interrupt forwarding group, and the subscriber 2a assigned telephone number N does not belong to any interrupt forwarding group, then the interrupt forwarding table (ITT) 131 , the group index G stored corresponding to telephone numbers N1, N, and N are all set to logic "1", and the group index G stored corresponding to telephone number N1 is set to logic +1QII. It is set.

Further, N, , Nf and N are stored as telephone numbers Nfi corresponding to telephone numbers Nb, N, and Nt, respectively, and subscriber 2b = 52. →It shows that they are connected in a ring in the order of 2t=+2b.

In FIGS. 2 and 3, subscriber 2. and 2. is in a talking state via the communication path pI set in the network (NW) 11, and subscribers 2 and 2f are in an idle state. State information S corresponding to telephone numbers N and N are each set to logic "1", and state information S corresponding to telephone numbers N and N are respectively set to logic "0".

In this state, subscriber 2b (transferring subscriber 2b)
Other subscribers belonging to the same interrupt transfer group2. (Forwarded Subscriber 2.) wishes to transfer a call to the other party Subscriber 2, and the forwarding Subscriber 2 verbally requests that the call be transferred to the Forwarded Subscriber 2. to request a predetermined interrupt transfer operation.

Transfer destination subscriber who received the request 2. makes a call, and uses the special number specified for interrupt transfer and the intra-group code C assigned to identify subscriber 2b within the interrupt transfer group.
Dial b.

When the central control unit (CC) 12 detects the call originating from the forwarding destination subscriber 2e and receives and analyzes the special number for interrupt forwarding, it activates the interrupt forwarding control section (ITF) 123 and performs the call in a known manner. The recognized telephone number N of the transfer destination subscriber 2e and the received intra-group code Cb are transmitted.

The activated interrupt transfer control unit (ITF) 123 reads the telephone number table (DN) provided in the main memory (MM) 13.
T) Referring to 132, the telephone number Nb of the transfer source subscriber 2b is determined based on the transmitted telephone number N0 and intra-group code Cb.
(Step Sl in Fig. 3).

Next, the interrupt transfer control unit (ITF) 123 transfers the main memory (
After setting the transmitted telephone number N as the set telephone number N8 in the work area (WA) 133 in MM) 13 (
Step S2), the interrupt transfer table (rTT) 131 in the main memory (MM) 13 is searched by the set telephone number N,=N, and the corresponding group index G="1" and the next telephone number N7=N. , is extracted (step S3).

Next, the interrupt transfer control unit (ITF) 123 uses the interrupt transfer table (
Since the group index G extracted from IT'J') 131 is set to logic "1", the transfer destination subscriber 2. When it is confirmed that 1 belongs to any interrupt transfer group (step S4), the interrupt transfer table (ITT), 1
The next telephone number N7 extracted from 2.31 and the transfer source subscriber 2.31 obtained in step S1. (step S5), this time the next phone number N7 is subscriber 2e.
's telephone number N, and the transfer source subscriber 2. phone number N
When it is determined that there is no destination, the next telephone number N7 and the forwarding destination subscriber 2. When it is determined that the next telephone number N1 and the telephone number N0 are not equal (step S6), the next telephone number N7=N is set as the set telephone number N8 and the work area (W
A) After setting within 133 (step S7), repeat execution from step S3.

This time, the interrupt transfer control unit (ITF) 123 receives the set telephone number N from the interrupt transfer table (ITT) 131.

Step S3) to extract the group index G=“1” and the next telephone number N−””Nb corresponding to Nf.
Group indicator G is set to logic "1" and subscriber 2. When it is confirmed that belongs to any interrupt transfer group (step S4), the interrupt transfer table (ITT
) 131, and the transfer source subscriber 2. In step S5), when it is determined that the next telephone number N7 is equal to the telephone number Nb of the subscriber 2a, the transfer source subscriber 2. is the destination subscriber 2. Make sure that it belongs to the same interrupt forwarding group as .

Next, the interrupt transfer control unit (ITF) 123 uses the interrupt transfer table (
ITT) 131, next phone number N, l=N.

to extract the status information S corresponding to the next telephone number N, =Nb (step S8), and the extracted status information S
is set to logic "1" (step S9), and since it is set to logic "1", transfer source subscriber 2. When it is confirmed that subscriber 2. is in a conversation state, the destination subscriber 2. is in a conversation state with the transfer source subscriber 2b. and transfer destination subscriber 2e are set in a talking state, and a busy tone is sent back to the transfer source subscriber 2b who was in a talking state, and the transfer destination subscriber 2e is set in a busy state (step 5IO).

Note that in step S4, the group index G is logic “0”.
”, the interrupt forwarding control unit (ITF) 123 determines that a subscriber outside the interrupt forwarding group has been searched for by mistake, and stops the interrupt forwarding service (step 511).

Further, in step S6, when it is detected that the next telephone number N7 is equal to the telephone number N of the transfer destination subscriber 2e, the interrupt transfer control unit (ITF) 123 determines that the transfer source subscriber 2b is the transfer destination subscriber 2. It is determined that the interrupt transfer service does not belong to the same interrupt transfer group as the interrupt transfer group, and the interrupt transfer service is stopped (step 511).

Furthermore, in step S9, if it is detected that step S is not set to logic "1", the transfer source subscriber 2b
It is determined that there is no call in progress, and the interrupt transfer service is stopped (step 511).

As is clear from the above description, according to this embodiment, the transfer destination subscriber 2e only needs to execute a predetermined interrupt transfer operation.
Transferring subscriber 2. 2. is the subscriber on the other end of the call without performing any operations. Transfer calls to subscriber 2. It becomes possible to transfer to.

Note that FIGS. 2 and 3 are only one embodiment of the present invention, and for example, the group index G is not limited to whether or not it belongs to any interrupt transfer group; identification of the beginning and end of a chain within a group, etc.
Although many other modifications may be considered, the effects of the present invention remain the same in any case. Also, transfer destination subscriber 2. is not limited to dialing a special number for interrupt transfer, and many other variations can be considered, such as operating a function button assigned to interrupt transfer on the telephone. However, the effects of the present invention remain the same in either case. Further, the transfer source subscriber 2b enters a busy state after transferring the calls with the two call destination subscribers to the transfer destination subscriber 2e, and is not limited to listening to the busy tone, but is in a calling state. Although many other modifications may be considered, such as listening to a dial tone, the effect of the present invention remains the same in any case. Furthermore, the configuration of the interrupt transfer group is limited to that shown in the drawings, and is not limited to that; many other modifications may be considered; however, the effects of the present invention remain the same in any case.

Furthermore, it goes without saying that the exchange to which the present invention is applied is not limited to that shown in the drawings.

〔Effect of the invention〕

As described above, according to the present invention, in the exchange, the transfer source subscriber does not need to perform the same operation in order to transfer the call with the destination subscriber to the transfer destination subscriber, and the transfer time is also shortened.
