Abstract

PURPOSE:To attain abbreviated dial service from an optional telephone exchange or an optional subscriber telephone set by registering a conversion table of abbreviated number versus opposite telephone number in a magentic card. CONSTITUTION:In making a call from an opposite subscriber by means of abbreviated dial, a card 1 on which an abbreviated number versus opposite telephone number conversion table is recorded is inserted at first to a telephone set provided with card reading function, then contents of the card 1 are stored in a memory 3 in a telephone set through a card interface 4 by a microprocessor 2. When the subscriber hooks off its handset 8 and dials an abbreviated number to the opposite subscriber number, the said dial signal is transmitted to the microprocessor 2 via a dialer 6. The microprocessor 2 identifies the dial signal and extracts the opposite subscriaber number corresponding to the dial signal from the memory 3. Then the microprocessor 2 controls the dialer 6 and transmits the opposite subscriber number to a telephone exchange.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speed dial telephone service system.

Conventionally, speed-dial telephone services dial a speed-up number that has been registered in advance from a specific subscriber's telephone.
The system received the call at the local telephone exchange, converted the abbreviated number to the subscriber's telephone number, and then connected to the called party.

FIG. 1 shows an example of this conventional method. In the figure, ■ is the shortened service subscriber, W is the other party's subscriber, X and Y are automatic exchanges, and ``XX'' is registered by subscriber V against subscriber W. Abbreviated number, “ABe DEF
GHJKJ indicates subscriber W's telephone number.

In such a configuration, when X station subscriber V makes a call to Y station subscriber W by speed dialing, subscriber V
is the abbreviated number “×” for subscriber W registered in advance.
Dial XX. At the X-station telephone exchange, “×××”
and subscriber W's telephone number rABCDEF' GH
Convert to JKJ and send to station Y. The Y telephone exchange receives rABCDEFGHJKJ and establishes an incoming call connection to subscriber W. Therefore, it is necessary for subscriber (2) to register an abbreviated number-to-destination telephone number conversion table in the X-office telephone exchange.

Therefore, subscriber V's speed dial service is
This is possible only in telephone exchanges, and has the disadvantage that speed dialing services cannot be obtained using other telephone exchanges or other subscriber telephones.

An object of the present invention is to provide a portable speed dialing system that eliminates the drawbacks of conventional speed dialing services and allows speed dialing services to be performed from any telephone exchange or any subscriber telephone. There is a K.

That is, in the present invention, by registering a conversion table between abbreviated number and telephone number of the other party in a magnetic card, the card can be inserted into a subscriber's telephone equipped with a card reading function, and the telephone can be accessed by dialing the subscriber's dial. It is configured to send out the other party's subscriber number. Therefore, according to the present invention, short i2i dialing service is possible at any location.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an embodiment of the portable speed dial system of the present invention.

In the figure, the abbreviated dial system of the present invention includes a card 1 on which an abbreviated number-to-destination phone number conversion table is recorded, and
On the telephone side, there is a card interface 4 that is detachably connected to the card 1, a memory 3 that stores the recorded contents of the card 1 that are input via the interface 4, and a memory 3 that stores the recorded contents of the card 1 that are input via the interface 4. It is constructed by providing a card reading function consisting of a microprocessor 2 which extracts the subscriber number of the other party and controls a dialer 6 to send out the number. In the figure, 5 is a ringer detection circuit, 7 is a hybrid circuit, and 8 is a handset.

In such a configuration, when making a call to the other subscriber using speed dialing, the present embodiment operates as follows.

First, when you insert the card with the abbreviated number-to-destination phone number conversion table into a telephone with a card reading function,
Microprocessor 2 provides card interface (
memory 3 in the phone through CARD INTF) 4
The contents of card 1 are stored in .

Then, when the subscriber picks up the handset 8 and dials the abbreviated number for the other subscriber's number, the dialing signal is transmitted via the dialer 6 to the microprocessor (μp) 2. The microprocessor 2 identifies the dial signal and retrieves from the memory 3 the subscriber number corresponding to the dial signal. After this, microprocessor 2
controls the dialer 6 and sends the subscriber number retrieved from the memory 3 to the telephone exchange.

As described above, the present invention enables a portable abbreviated dialing service by having a card with an abbreviated number-destination subscriber number recorded thereon and a telephone with a card reading function.
