Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a manual transfer system in a telephone exchange.

(b) Prior art and problems Conventional telephone exchanges provide incoming call forwarding as a manual forwarding service, and in the case of private branch exchanges, outgoing call forwarding is also provided, but the call is forwarded after the subscriber attempts to manually forward the call. If you dial a number, talk to the forwarding party, and then need to transfer the call to another party, you will need to hook up, return to the original call, dial the new forwarding number again, and then dial the number. The drawback was that it required a long time to wait for the person on the other end of the line.

(c) Purpose of the Invention The present invention solves such conventional drawbacks, and allows a manual transfer person to manually transfer to the next transfer destination without returning to the original call when the need for further transfer arises during a call with the transfer destination. This provides a manual transfer method that reduces waiting time for the other party by connecting the other party.

(d) Summary of the Invention The present invention provides means for detecting hooking from a subscriber during a call, means for putting the call on hold, and means for receiving a forwarding number by a dial signal from the subscriber (manual forwarder). , in the manual transfer method of a telephone exchange that transfers a call based on the forwarding destination number by hooking and dialing from the subscriber (manual forwarder), the subscriber (manual forwarder) further transfers the call while the subscriber (manual forwarder) is talking with the forwarding destination. In this case, after hooking from the subscriber (manual transferer), the call is connected to the next transfer destination using the transfer destination number using a dial signal without returning to the original call.

(e) Embodiments of the invention Next, embodiments of the invention will be described with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention, and shows a network (NW) 5 of an exchange A and subscribers A1, C3, and D accommodated therein.
4, Incoming trunk (ICT) 7, Outgoing register trunk (ORT) 9, 13, Ringing trunk (RBT)
10, 14, internal trunk (IOT) 11, 1
5. Consists of ring signal trunks (RGT) 12, 16, network (NW) 6 of exchange B, subscriber B2 accommodated therein, and outgoing trunk (OGT) 8.

The operation of the present invention will be explained step by step with reference to the figures below. When subscriber A1 and subscriber B2 are talking via network 5 - incoming trunk 7 - outgoing trunk 8 - network 6, when subscriber A1 leaves the network and needs to be replaced by subscriber C3, subscriber A1 Since hooking is performed after notifying subscriber B2 of manual transfer, this is detected by incoming trunk 7. When hooking is detected on the incoming trunk 7, the subscriber A1 is reconnected to the outgoing register trunk 9 via the network 5 while the incoming trunk 7 is kept on hold. When the calling register trunk 9 receives the forwarding destination number in the dial signal from the subscriber A1, the subscriber A1 is connected to the ring trunk 10 via the network 5, and then connected to the subscriber C3 via the network 5. Connect trunk 12. When subscriber C3 answers, a response is detected in the paging trunk 12, and subscriber A1 and subscriber C3
is connected to the trunk 11 within the local office via the network 5, and a call is made.

Here, if subscriber A1 needs to further transfer to subscriber D4, conventionally, if subscriber A1's hooking is detected on trunk 11 within the own station, incoming trunk 7
The connection was changed to subscriber D4 via network 5, the initial state was returned, and a new transfer sequence to subscriber D4 was proceeding. In the present invention, when the hooking of subscriber A1 is detected on the local trunk 11, the connection is changed to the originating register trunk 13 via the network 5, and if a dial signal is not received within a certain timing, the connection is switched via the network 5 to the incoming trunk. 7
Change the connection to. On the other hand, if a forwarding destination number is received by a dial signal within a certain timing, the subscriber A1 is transferred to the ring trunk 1 via the network 5.
4, and further connects the subscriber C4 to the calling signal trunk 16 via the network 5. When the subscriber D4 responds, the response is detected by the calling signal trunk 16, and the subscriber A1 and the subscriber D4 are connected to the in-house trunk 15 via the network 5, and the call is made. When the disconnection of subscriber A1 is detected on the trunk 15 within the own station, subscriber D4 switches the connection to the incoming trunk 7 via the network 5, and connects subscriber D4.
4 and subscriber B2.

Manual transfer performed as described above can be performed not only for incoming call transfer but also for outgoing call transfer.

(f) Effects of the Invention As explained above, the present invention performs means for detecting hooking from a subscriber during a call, means for putting the call on hold, and forwarding of a call using a forwarding destination number based on a dial signal from the subscriber. In the manual transfer system of telephone exchanges, when a subscriber transfers a call while the subscriber is communicating with a transfer destination, the subscriber is connected to the next transfer destination without returning to the original call, thereby reducing the waiting time of the other party. It has the effect of reducing

Claims (1)

[Claims] 1. A means for detecting hooking from a subscriber during a call, a means for putting the call on hold, and a means for receiving a transfer destination number by a dial signal from the subscriber is provided, and after hooking from the subscriber, transfer by dial signal is provided. In the manual transfer system of a telephone exchange that transfers calls based on the destination number, if the subscriber wants to transfer the call further while the subscriber is talking to the destination, after hooking from the subscriber, the call is transferred back to the destination number using a dial signal. A manual transfer method characterized by connecting to the next destination without returning to the destination.
