Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone number search method, and more particularly to a telephone number search method capable of remotely accessing a telephone number registered in advance in an exchange.

[0002]

2. Description of the Related Art In recent information communication systems, various services can be provided. For example, there is a service in which a telephone set in a subscriber's home registers a speed-dial telephone number in an electronic exchange and the registered speed-dial telephone number can be used.

In this conventional service, only a subscriber who has registered a shortened telephone number can use the shortened telephone number registered by the subscriber.

[0004]

However, the above-mentioned conventional service has a problem in that the subscriber cannot use the shortened telephone number registered by himself / herself from an external telephone other than his / her home.

In view of the above-mentioned point, the present invention is a telephone number search method in which anyone who satisfies a certain condition can use the telephone number registered by a certain subscriber even from an external telephone. The purpose is to provide.

[0006]

In order to achieve the above object, the telephone number search method of the present invention checks at least the telephone number and password of a predetermined subscriber when a predetermined fixed telephone number is input. In addition, when the passwords for the telephone numbers match when checked, a predetermined subscriber can access the shortened telephone number registered in advance. Here, in order to access the abbreviated telephone number, the abbreviated telephone number may be expanded and the telephone of the person who has accessed the expanded telephone number may be connected.

According to the present invention, when a subscriber who has a shortened telephone number service has registered the shortened telephone number, a fixed telephone number is dialed from outside, then the subscriber's telephone number is dialed, and a password is entered. By inputting, it is possible to use an abbreviated telephone number registered in advance by a predetermined subscriber.

[0008]

The present invention will now be described with reference to the illustrated embodiments.

FIG. 1 is a block diagram showing a telephone exchange system which realizes the telephone number search method of the present invention.

The telephone network shown in FIG. 1 is a telephone set 1 of a subscriber A.
Is connected to the electronic exchange 5 via the telephone line 3.
The electronic exchange 5 is connected to the exchange network 7. It is assumed that an external telephone 9 is connected to the exchange network 7 via lines 11 and 13.

A procedure for registering a shortened number using such a telephone network will be described.

FIG. 2 is a flow chart for explaining the operation of allowing the subscriber to remotely access the shortened telephone number. It is assumed that the subscriber A has a shortened telephone number service and the subscriber B wants to use the shortened telephone number registered by the subscriber A.

The subscriber A puts the handset on-hook from the telephone 1 at home or presses the monitor button to register the desired telephone number to the exchange 5 (step S100). Then, the subscriber A judges whether or not the remote access is permitted (step S101), and if the remote access is permitted (step S101; Y), the shortened telephone number remote access permitted password is dialed and the exchange 5 is exchanged.
(Step S102). Then, the handset is hooked on the telephone or the monitor button is pressed again to finish the process.

If the subscriber A does not allow the remote access (step S101; N), the subscriber A does not do anything and ends the operation by on-hooking the telephone or pressing the monitor button again. In this case, remote access is not possible.

Next, the operation for remotely accessing the shortened telephone number will be described with reference to FIG. In this case, the subscriber A or the person B who has taught the password can also remotely access. Here, FIG. 3 is a flowchart for explaining an operation in which the abbreviated telephone number registered by a certain subscriber is remotely accessed by the principal or another person.

The subscriber A or B dials the abbreviated telephone number remote access telephone number (a fixed telephone number) from the external telephone 9 (step S20).
0), dial the telephone number of subscriber A (step S
201). Next, the subscriber A or B dials the speed-dial telephone number (step S202), and then dials the password (step S203).

Then, when these numbers are input from the telephone 9 to the exchange 5 via the exchange network 7, the exchange 5 will be set in FIG.
It operates like the flowchart shown in FIG. 4. Here, FIG. 4 is a flow chart for explaining the internal processing operation of the exchange 5 when there is a dial-in as shown in FIG.

A short-distance telephone number for remote access from the subscriber A or B using the telephone 9 is used for the switching network 7.
Is received, the remote access operation is started by connecting to the exchange 5 (step S300). Next, exchange 5
Receives a telephone number for remote access (step S301). At this time, the exchange 5 checks whether or not the received telephone number has a shortened telephone number service (step S302). When the exchange 5 determines that it does not have the shortened telephone number service (step S302; N), the exchange 5 performs error processing (step S303) and ends the processing. When the exchange 5 determines that it has the speed-dial telephone number service (step S302; Y), it receives the speed-dial telephone number (step S304). The exchange 5 checks whether remote access is permitted for the received speed-dial telephone number (step S305). If remote access is not permitted (step S305; N), the exchange 5 performs error processing (step S306) and ends the processing. When remote access is permitted (step S305; Y), the exchange 5 receives the password (step S307) and checks whether the password matches the registered password (step S308). When the exchange 5 determines that the passwords do not match (step S308; N), it performs error processing (step S309) and ends the processing. On the other hand, when the exchange 5 determines that the passwords match (step S308; Y), the exchange 5 develops the abbreviated telephone number and connects the telephone 9 used by the subscriber A or B to the developed telephone number. Then (step S310), the process ends.

As described above, in this embodiment, the password is also registered when registering the abbreviated number, the remote access telephone number is dialed when the abbreviated telephone number service is subsequently received, and the subscriber of the abbreviated number registered here is registered. By dialing the telephone number of, and dialing the abbreviated number and the password, anyone who knows the password can use the registered abbreviated telephone number.

[0020]

As described above, according to the present invention, a subscriber can have a short-distance telephone number by dialing a remote access telephone number from the outside, dialing a necessary telephone number, and inputting a password. There is an effect that other people can use the speed-dial numbers as they are.
