Abstract

PURPOSE:To attain transmission from any telephone set by means of an abbreviated code by dialing a telephone number and an abbreviated code of a contracted subscriber. CONSTITUTION:An abbreviated dial list is obtained from a contracted subscriber telephone number by storing an address of an abbreviated dial list in an incom ing translated word (TERTLR) in memory architecture of a storage device 5. At first, a telephone number of ABCDEFGHIJ and an abbreviated code *DELTADELTAof a contracted subscriber are dialed from an optional sender telephone set X. An exchange 1 uses are received number to make connection to an exchange 3 via an exchange 2. In this case the abbreviated code *DELTADELTA is transmitted to the exchange 3 together with the telephone number of the contracted subscrib er. The exchange 3 obtains the incoming translated word by using the telephone number of the received contracted subscriber and uses the abbreviated code *DELTADELTAto extract the dial number corresponding to the abbreviated dial list and the number is translated by the extracted dial number to make connection to an incoming subscriber Y.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a speed dial system in telephone exchange services.

[Background of the invention]

In the conventional abbreviated dialing system, abbreviated codes registered in advance by a subscriber and corresponding dial numbers are recorded in a storage device of an exchange in correspondence with the storage position of a telephone.

Therefore, the use of the shortened code is limited to the corresponding telephone, and there is a drawback that the shortened code cannot be used to make a call from any telephone.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to make it possible to make a call using the short code from any telephone by dialing the subscriber's telephone number and the short code.
There is C.

[Summary of the invention]

The present invention stores abbreviated codes and corresponding dial numbers in a storage device of an exchange in which a contract subscriber is accommodated, not only corresponding to the contract telephone, but also corresponding to the contract subscriber's identification number. By dialing the subscriber identification number and the abbreviated code, it is possible to make a call from an unspecified telephone using the abbreviated code.

(Example of the invention) The present invention will be explained below with reference to one drawing.

FIG. 1 is a conceptual connection diagram for explaining one embodiment of the present invention. In the figure, A is the contracted subscriber, X is any calling subscriber, %Y is any receiving subscriber who receives a call by dialing an abbreviated code, ABCDgFGHJ is the subscriber's identification number, A'B'C'D'E'
F'G'H'J't-1 Optional Telephone number of the receiving subscriber Y, and ΔΔ is an abbreviated code. In this example,
A system is adopted in which telephone numbers are used as identification numbers for contracted ministries.

In addition, 1 is an exchange that accommodates an arbitrary originating subscriber be. Further, numeral 5 is a storage device that stores abbreviated dial information of contract subscribers.

Figure 2 shows the subscriber's telephone number and accommodation location.

FIG. 2 is a memory configuration diagram for storing information such as abbreviated codes and dialed numbers corresponding to the abbreviated codes. 0 in the diagram
RTLR is the outgoing translation word corresponding to the subscriber's accommodation location, VABL8T is the speed dial list that stores the dial numbers corresponding to the speed code, and TERTLRG! This is the incoming translation word that corresponds to the subscriber's phone number. By storing the address of the speed dial list in this incoming translation word, it becomes possible to obtain the speed dial list from the contract subscriber's telephone number. In addition, IJN in the figure is the accommodation location of the contract subscriber, DN. is the telephone number of the subscriber, Δ
Δ is an abbreviated code.

') This is the dial number corresponding to the X abbreviation code ΔΔ.

Hereinafter, based on FIG. 1, the connection operation from dialing the telephone number ABCDEFGHJ and abbreviation code *ΔΔ to the contracted subscriber from an arbitrary telephone X to receiving the call to the receiving subscriber Y will be explained.

First, the subscriber's IE honor code ABCDEFGHJ and the abbreviation code *ΔΔ are dialed from the calling telephone X of the EE. Exchange 1 connects to exchange 3 via exchange 2 based on the received number. In that case, short code *ΔΔ
It is also sent to the exchange 3 together with the contract subscriber's telephone number.

The exchange 3 uses the telephone number of the contracted subscriber received to obtain the translated word for the incoming call, then extracts the corresponding dialed number from the speed dial list using the shortened code ΔΔ, translates the number using the extracted dialed number, and receives one incoming call. A connection is made to subscriber Y.

(The underlined operations are functions that have already been implemented in call forwarding services.) As explained above, by matching the subscriber's phone number with the speed dial list, it is possible to make short code calls from any phone. shall be.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible for a subscriber to make a call from any telephone using the subscriber's number and abbreviation code, thereby improving serviceability.
