Abstract

PURPOSE:To dial dial numbers while changing only different dial numbers without dialing of all digits by storing a dial number dialed finally and dialing while changing part of the dial number when a similar number to the stored dial number is dialed. CONSTITUTION:A terminal equipment 1-2 whose extension number is '201' is called from a terminal equipment 1-1 and one digit '2' is dialed while the preceding dialing is made, then a terminal equipment 1-3 whose extension number is '202' is called. Moreover, while the terminal equipments 1-1, 1-2 are busy, when the caller terminal equipment 1-1 dials one digit '2', the terminal equipment 1-2 is opened and the terminal equipment 1-3 whose extension number is '202' is called. Moreover, the terminal equipment whose extension number is '202' is called by dialing one digit '2', from the caller terminal equipment 1-1 while the called party terminal equipment 1-2 hooks up a handset from the busy state.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a telephone exchange system, and particularly when dialing the same number as the last dialed number or dialing a number similar to the last dialed number. The present invention relates to a redialing method suitable for cases where

[Conventional technology]

Traditionally, telephone switching systems memorize the last dialed number and re-dial the same number. There is a method of transmitting dialed numbers by changing the first digit of the number.

[Problem to be solved by the invention]

In conventional systems, if you want to dial a number that is close to the last number you dialed, you have to re-dial all the digits. In such a case, if there are a large number of dials, there is a drawback that dialing takes time. In addition, in conventional systems, it is possible to send dialed digits by changing the first digit of the dialed digit when the called party is busy or when the called party is on the line, but if the other party hangs up the handset during a call or during a call. In this case, it was not possible to continue sending dialed digits.

[Means to solve the problem]

The present invention is a special feature of a telephone switching system, in which the last dialed digits are memorized, and when a number similar to the memorized dialed digits is dialed, the dialed digits are partially changed before making a call. According to the invention, not only can the dialed digits be memorized and the same number as the memorized dialed digits re-dialed, but also when the user wants to call a number similar to the memorized number, the user can call a number similar to the memorized number without having to dial all the digits. It becomes possible to make a call by changing only the different dial numbers.

〔Example〕

Examples of the present invention will be described below.

First, an example of a method for redialing by changing only one digit will be described. In Fig. 1, the terminal device 1-1 calls the terminal device 1-2 with extension number "201", and from the calling state (2-3 in Fig. 2), the first digit "2" is dialed. By doing so, the extension number ``202''
Terminal device 1-3 is called. In addition, when the terminal device 1-1 and the terminal device 12 are in a conversation state (Fig. 2, 2-5), by dialing a single digit "2°" from the terminal device 1-1 on the calling side, the terminal device 1-1 -2 and extension number ゛20.
2" calls the terminal device 1-3. Also, from the state in which the called terminal device 1-2 is on the phone (Fig. 2, 2-5) to the state in which the called terminal device 1-2 has put down the handset (Fig. 2, 26), Outgoing terminal device 1

202”.The contents shown above are as follows:
This is effective not only for extension lines but also for central office lines and dedicated lines.

Conventionally, the terminal device 12 is called from the terminal device 1-1, and the extension number is determined from the call status (Fig. 7, 7-1) and the state where the called party has hung up the handset (Fig. 7, 72). number"
When calling the terminal device 13 of ``202'', it was necessary to put down the handset and dial all the digits as ``202''. By dialing "2" from the handset down state (Fig. 8, 8-2), it is possible to call the extension number "202", which is different from the conventional handset (Fig. 7, 7-2) when the handset is down.
3) Dial all digits as "'202" (Figure 7, 7-
4) Operation can be omitted.

Next, a redialing method will be explained. The caller lifts the handset and dials 200' (Figure 3, 3-2)
), the type (
(extension line, central office line, dedicated line, etc.) and dialed numbers are registered,
By dialing a single digit "1" during a call and with the called party hanging up the handset, the first digit in the registration area is changed and dialed "201" is sent.

〔Effect of the invention〕

According to the present invention, even if the other party hangs up the handset during a call or after the call ends, it is possible to change the end of the previously dialed content and dial again, making it possible to make a reset call with a simple operation. .

Claims (1)

[Claims] 1. In a telephone exchange system, a redialing method is characterized in that dialed numbers are stored for each terminal device, and the stored dialed numbers are re-edited at any time and then dialed.
