Abstract

PURPOSE:To attain the communication with an optional kind of terminal equipment at a called party side even when the numbers of various terminal equipments of a section of the called party are not memorized entirely by sending caller terminal kind information together with a selection signal at dialing and allowing the called party to retrieve the same kind of called terminal equipment as the caller side at the incoming call section and transferring the signal. CONSTITUTION:When attribute information of a caller terminal, that is attribute information representing 'FAX' is sent from a caller exchange 1 to a called exchange 2 together with a dial signal '770-100' through an ISDN line 5, the called exchange 2 analyzes an incoming signal with a number conversion table 3 to detect the dial number and caller terminal attribute information and to discriminate whether or not the terminal number in the sent dial number is coincident with the kind and the incoming call is connected to a terminal equipment of the destination dial number.

Description

[Detailed Description of the Invention] [Summary] In a communication network that accommodates multiple types of terminals such as telephone, fax, and data terminals, when a call is received to a terminal of a different type than the calling party, the number of the received call is Regarding the call forwarding service method, which converts the number and transfers the call to the same type of terminal as the calling party, remember all the dial numbers of the various terminals in the called party section (but if you know one of them, you can use that number) The purpose of this is to enable communication to any type of terminal on the called side using the terminal, and the called side has one or more receiving sections divided into groups of terminals including multiple types. A number conversion table containing terminal numbers and type information is provided, and the calling side transmits the calling terminal type information along with a selection signal when making a call, and the receiving side converts the number of the called terminal and the calling terminal type information from one incoming signal. Based on the number conversion table of the incoming section determined from the number of the incoming terminal, the incoming call is searched for in the incoming section for the same type of incoming terminal as the calling party, and the incoming call is transferred to that incoming terminal.

[Industrial Application Field] The present invention is applicable to telephones, facsimiles (hereinafter referred to as FAX)
, in a communication network that accommodates multiple types of terminals such as data terminals, when a call is received to a terminal that is of a different type than the calling party, the number of the incoming call is converted and automatically transferred to a terminal of the same type as the calling party. Concerning an automatic forwarding service method for forwarding.

[Prior Art] For example, in a company, each department or section (hereinafter referred to as a section) is equipped with several telephone extensions, fax terminals, data terminals, etc. A number is given. If the caller is making a call from a telephone, the external caller must provide the telephone number of the called party, or if the call is being made from a fax terminal, the called party's FAX number must be entered.
Correct communication cannot occur unless each number is dialed.

[Problem to be Solved by the Invention] Conventionally, the caller had to remember all the numbers for each type of communication, even if the caller was communicating to the same section, since the numbers differ depending on the type of communication. For example, in many cases, only the phone number or fax number is known.

For this reason, for example, in the case of FAX communication, the sender
If you don't know the number for X, you will have to call the other party for the fax number and then send the fax, which results in twice the effort, which reduces work efficiency and also leads to long line hold times. In addition, if the fax terminal on the receiving side is located far away from the person in charge, the person in charge may not be able to tell immediately if there is an incoming fax, and the person in charge may There is also the problem of poor work efficiency, such as having to constantly watch the other party or calling the other party to make inquiries.

Therefore, the present invention does not require you to remember all the numbers of the various terminals in the terminating section (or if you know one of them, you can use that number to communicate with any type of terminal in the terminating section). The purpose is to improve communication efficiency and shorten line holding time.

Another purpose of the present invention is to improve the convenience of the - layer by making it possible to automatically notify by voice when a call arrives at a FAX terminal or the like.

[Means for solving section m] FIG. 1 is a diagram explaining the principle of the present invention.

In Figure 1, ■ is the originating exchange (for example, PBX),
2 is a terminating exchange (for example, PBX), and the originating exchange 1 has a terminal of a different type, for example, a general extension telephone 11.
．． A FAX terminal I2 and a data terminal 13 are accommodated, and similarly, the destination exchange 2 accommodates, for example, an extension telephone 21, a FAX terminal 22, and a data terminal 23. Exchange 1 and 2
The terminals are connected by a communication line 5, such as an 15DN line, which can transmit not only a dial number but also type information (also referred to as attribute information) of the originating terminal, such as ``what kind of terminal is the communication from?''.

In the destination exchange 2, the terminals accommodated therein are
Each section is divided into one or more incoming call sections including a plurality of types, and a number conversion table containing the number and type information of the terminal in the incoming section is provided in correspondence with each incoming call section.

Further, 4 is a talkie device capable of transmitting a voice message such as ``A fax has just arrived.''.

The basic form of the automatic forwarding service system according to the present invention is that the calling side transmits calling terminal type information along with a selection signal when making a call, and the called side detects the called terminal dial number and calling terminal type information from the incoming signal. Then, based on the number conversion table 3 of the receiving section determined from the dialed number of the receiving terminal, the system searches for a receiving terminal of the same type as the calling party in the receiving section and transfers the call to that receiving terminal. .

In addition to the above-mentioned configuration, the call forwarding service system according to the present invention has an arrangement in which, when a call is received on a terminal other than a telephone terminal, a voice call is received by the talkie device 4 to the telephone terminal in the call receiving section. This is to notify you.

[Operation] When making a call from the calling side exchange I'll, type information indicating the type of the calling side terminal is also added and transmitted together with the selection signal (dial number) of the called side. This allows the receiving side to learn the type of terminal on the calling side by analyzing the incoming signal, and then determines which section the other party wishes to communicate with from the terminal number information in the dialed number, and responds to that section. The selection signal is converted into a receiving terminal number of the same type as the calling side based on the number conversion table 3, and the incoming call is connected to the converted number.

In addition, when a talkie device 4 is provided, for example, after the FAX communication is completed, the talkie device sends a voice notification of FAX@ to the extension telephone 21 nearest to the FAX terminal 22 to receive the communication. This will make learning even more convenient.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings. In this embodiment, the basic communication system shown in FIG. 1 is used, and the automatic transfer service method of the present invention is used. This is a memory device that performs detection and judgment, and converts a received dial number into a number assigned to a receiving terminal with the same attributes as the calling party. In this number conversion table, general extension telephones, nearest FAX terminals, data terminals, etc. are divided into sections, and the extension numbers, FAX numbers, and data terminal numbers are registered in advance for each section. In the embodiment, only one section consisting of an extension telephone 21, a FAX terminal 22, and a data terminal 23 is shown to simplify the explanation.

An l5DN line is used as the communication line 5, and this l5DN
Dial digits from the calling party over the line's control channel,
It is assumed that a calling terminal attribute report is sent.

Here, the station number of the originating exchange 1 is 700'', and the station number of the destination exchange 2 is 770'''.

In addition, each of the extension telephone 21, FAX terminal 22, and data terminal 23 on the receiving side is
Assume that a terminal number 00'' is given.

Examples will be described below with reference to FIGS. 2 and 3. Here, FIG. 2 is a diagram illustrating the connection path according to the embodiment,
FIG. 3 is a flowchart illustrating the connection processing procedure on the called side.

The caller is now using FAX terminal I2 to send the FAX to the called party.
It is assumed that FAX communication is to be performed to the terminal 22. Here, the caller dials the dial number "770-200" of the called party's FAX terminal.
” because I didn’t remember it correctly, so I got the wrong number “77”.
0-100" is dialed. This dialed number "770-100" is originally addressed to the extension telephone 21.

When the above dialed number is transmitted from the originating exchange 1 to the terminating exchange 2, the attribute information of the originating terminal, that is, the attribute information indicating that it is rFAXJ, is transmitted to the 15DN line 5 along with this dial signal "'770-1oo"'. sent through.

On the receiving side exchange 2 side, this incoming call is guided to the number conversion table 3 via the route 2, the incoming signal is analyzed to detect the dial number and the calling terminal attribute information (step S2), and the type of communication is determined from the attribute information. “General extension phone” or rFA
To determine whether it is an XJ or a "data terminal" (step S3), it is determined whether the terminal number in the sent dial number matches the type (steps 84 to S6). If these match, the calling and receiving terminals are of the same type and communication is possible, so the incoming call is connected to the terminal with the destination dialed number (
Step 510).

On the other hand, as mentioned above, if the dial number is "770-100" even though it is addressed to the FAX terminal 22,
If the attributes of the called terminal corresponding to the dialed number do not match the attributes of the calling party, refer to the number conversion table 3 to check the number of the called terminal that has the same attributes as the calling party, and then send the received terminal number. The receiving terminal number is converted into a receiving terminal number having the same attribute as the receiving terminal number (steps 87 to S9). In other words, in the above example, the "extension" terminal number "100-" in the received dial number is
Convert to FAXJ terminal number “200” (step S7
). Then, after performing this conversion, route the incoming call ◎
Connect to the FAX terminal 22 as in (Step 5IO)
.

Furthermore, if the exchange 2 detects a disconnection signal from the receiving FAX terminal 22, it assumes that the FAX communication has been completed normally, and then sends a call to the nearest extension telephone of the FAX terminal 22 via the route ■. - The device 4 is connected and the talkie device 4 notifies the incoming call by voice. The content of this notification may be, for example, "A facsimile has just arrived."

In addition, in the above example, the section was explained as one, but if there are multiple sections, the section to which the terminal belongs is searched from the terminal number in the received dialed number, and the above-mentioned transfer process is performed. .

[Effects of the Invention] By using the method of the present invention, when communicating to the same section, as long as you remember one number in that section, regardless of the type of terminal you use, you can easily remember that number. For example, when making a FAX communication, there is no need to inquire about the FAX number, and the line hold time can be shortened. Furthermore, if a talkie device is provided on the incoming call side, the presence or absence of an incoming call can be immediately known by voice, leading to improved work efficiency.
