JPH03185957A - Selective incoming call transfer system by exchange identifying terminal equipment - Google Patents

Abstract

PURPOSE:To allow an exchange to select and connect a relevant terminal equipment automatically even when a caller does not know the terminal equipment number of the called party but knows the telephone number by allowing an exchange to manage a facsimile terminal equipment and an installed area. CONSTITUTION:When a caller A sends a document from a facsimile terminal equipment 100 to a called party B terminal equipment 101, since the caller does not know the telephone number of the terminal equipment 101, the telephone number 200 is called. The number 200 is identified by a register circuit and a control section 105 retrieves a transfer management table to collate the terminal class of telephone numbers 100, 200 and to detect the dissidence and to retrieve the terminal equipment 101 of the same area as the number 200 registered in the management table. Then the control section 105 collates the terminal class of the terminal equipment 100 and the terminal class of the terminal equipment 101 and connects the line when the class is the same. Thus, even when the terminal number of the called party is unknown but the telephone number is known, the exchange selects the relevant called party terminal equipment automatically and makes connection to attain the communication.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switching system transfer system, and in particular, a method for identifying calls made by different types of terminals and automatically selecting a communicable terminal near the called party. Concerning the transfer method of connected calls.

Conventional technology Conventionally, in the forwarding system of exchanges, the called party sets the forwarding source in advance, and after the forwarding is set, the corresponding telephone (
Generally, calls received at a terminal (or a terminal) are unconditionally transferred to a set transfer source, that is, transfer is possible only between terminals of the same type.

Problems to be Solved by the Invention However, in the conventional transfer system of exchanges, transfer is performed unconditionally regardless of the type of terminal on the calling side, so communication may not be possible when the type of terminal is different, and From the calling side's point of view, there was a drawback in that they could not communicate with the called terminal unless they knew the telephone number of each terminal in addition to the telephone number of the calling party.

That is, if the calling party wishes to communicate with a terminal other than the other party's telephone (for example, a facsimile), there is a problem in that the calling party must know the telephone number of the facsimile in addition to the telephone number of the other party's telephone.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new selective call transfer method for an exchange that makes it possible to solve the above-mentioned problems inherent in the prior art.

Means for Solving the Problems In order to achieve the above object, the call transfer method according to the present invention includes a means for identifying the type of accommodation equipment corresponding to a telephone number, and a means for identifying the type of accommodation equipment corresponding to a telephone number, and a means for identifying the type of accommodation equipment corresponding to a telephone number. A means of searching for the telephone number of a terminal in the area, and a method that allows communication within a terminal installed near the called party's telephone if the calling party's terminal is not a telephone when a call arrives at the called party's telephone. and means for selecting and connecting a terminal.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG.
The figure shows an example of a transfer management table.

Referring to FIGS. 1 and 2, in this embodiment, facsimile terminals 1 with subscriber numbers #100 and #101
00.101 and the telephone 102 are connected to the exchange section 10 of the exchange.
Connected to 3. Of these, facsimile terminal 101
is installed in the same area (nearby area) as the telephone 102.

The exchange unit 103 also includes a register circuit 104 that identifies a called party number when a call arrives, and a control unit 105 that controls call connection.
is connected, and the control unit 105 manages a transfer management table 106 for searching for the telephone number of a terminal in the same area as the telephone from the telephone number, the terminal type of the subscriber, and the subscriber number of the telephone. There is.

An example of the operation of the above configuration of the present invention is as follows.

First, calling party A sends a message to called party B from the facsimile terminal 100.
When sending a document by facsimile to the called party B, the caller calls the called party B's telephone number #200 because he or she does not know the telephone number #101 of the facsimile terminal 101 of the called party B.
.

Telephone number #200 of called party B is identified by register circuit 104 and notified to control unit 105 (■).

The control unit 105 searches the transfer management table 106 and collates the terminal types of the calling party A's subscriber number #100 and the called party B's subscriber number #200. This detects a mismatch between the calling party's terminal type (facsimile) and the called party's terminal type (telephone), and transfers the call without connecting it to terminal 102 with telephone number #200 (■). Management table 10
Search for terminal number #101 in the same area as phone number #200 registered in 6.

Next, the control unit 105 checks the terminal type of the calling subscriber number #100 and the terminal type of the above-mentioned terminal number #101, and since they are the same type, the line is connected (■).

As described in detail, according to the present invention, by managing the type and installation area of the terminal in the exchange, the caller can easily access the called party's facsimile terminal even if the caller does not know the telephone number of the called party's facsimile terminal. As long as the telephone number is known, the exchange automatically selects and connects the called terminal corresponding to the calling terminal, thereby enabling communication.
