Abstract

PURPOSE:To expand the registration of opposite subscriber number by storing a subscriber number common part as a pointer data to a subscriber number common part storage area so as to use efficiently the memory. CONSTITUTION:The opposite subscriber number inputted from a key input section 4 by the predetermined registration method at a control section 2 is stored in the memory 3. When a call is instructed from the key input section 4 and the K-th opposite subscriber is selected, a memory address #K storing the subscriber number of the opposite subscriber is assigned. A number data 0123 is read from the subscriber number common part storage area A directed by a pointer data at the address #K and connected to a number data 45-6789 after the pointer data of the address #K becomes the complete opposite subscriber number 0123-45-6789 and is sent to a communication exchange network via a telephone circuit 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a subscriber number storage device in a communication terminal device such as a telephone device having a memory for storing the subscriber number of the other party.

2. Description of the Related Art Conventionally, in a telephone device having a telephone number memory function, abbreviated numbers such as 00 to 1 are stored in a speed dial system.
In the one-touch dialing method, the key assigned to the one-touch dial and the other party's subscriber number are associated with each other and registered in memory in advance. By making a call, you can connect to the other party.

FIG. 3 shows the storage form of subscriber numbers in the memory of a conventional subscriber storage device. In FIG. 3, reference numeral 1 denotes a subscriber number storage area of the memory, in which the subscriber number is registered by an operation determined by the telephone device. #1~#
n is the subscriber number storage address of n counterpart subscribers. When making a call, when, for example, the number of the other party is selected by a predetermined operation, address #k of the memory where this number of the other party is stored is determined, and the number of the subscriber stored here is determined. The number (012'3-45-6789) is read and sent. (However, in reality, the high phono "-" is not transmitted.) Problems to be Solved by the Invention However, in the above conventional example, the subscriber number storage area 1
stores all the numbers necessary to connect to each subscriber, so even if multiple subscribers have a common area code, each subscriber number storage area 1 stores the area code. has to be memorized, which has the disadvantage of wasting memory.

The present invention is intended to eliminate the drawbacks of the conventional example, and aims to increase the number of registered subscriber numbers by efficiently using memory.

Means for Solving the Problems In order to achieve the above object, the present invention provides a subscriber number for storing a common number part among a plurality of partner subscribers (for example, a part corresponding to a common area code). A common part storage area is provided, in which the number data of the subscriber number common part is stored, and for the other subscriber who has a subscriber number including this subscriber number common part, this subscriber number common part is stored in the subscriber number common part. This is stored as pointer data to the common number storage area to improve memory efficiency.

Operation The present invention has the above-described configuration, and since the common number portion is stored in the same storage area of the memory, memory efficiency can be improved.

Embodiment FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. In the figure, 2 is a control unit, 3 is a memory, 4 is a key human power unit,
5 is a display section, and 6 is a telephone circuit section. The memory 3 is for storing the subscriber number of the other party, and the display section 5 is for displaying various information such as the subscriber number of the other party at the time of registration or making a call.

FIG. 2 shows the structure of the partner subscriber number stored in the memory 3 in this embodiment. In the figure, A is a subscriber number common part storage area, B is an individual subscriber number storage area, and B is a pointer to the subscriber number common part storage area A, and a non-common part of the data area 7 and the subscriber number. It consists of a number data area 8.

In FIG. 1, the subscriber number of the other party manually input from the key input section 4 is stored in the memory 3 according to a registration method predetermined by the control section 2. The structure of the stored partner subscriber number is as shown in FIG. Here, the control unit 2
When there is an input from the keypad unit 4 instructing to make a call using a predetermined operation method, the control unit 2 reads out the subscriber number of the other party from the memory 3 according to this input information, and transmits this number via the telephone circuit unit 6. and sends it to the communication switching network. At this time, in FIG. 2, for example, when the th partner subscriber is selected according to the above procedure, first, address #k of the memory where the subscriber number of this partner subscriber is stored is determined. Next, number data (012
3-) is read out and concatenated with the number data (45-6789) following the pointer data at address # to form the complete partner subscriber number (0123-45-6789) and sent out.

In this way, this embodiment has the advantage of improving memory efficiency because it eliminates the waste of storing a common area code redundantly.

Effects of the Invention The present invention has the above-mentioned configuration, and according to the present invention, by efficiently storing the subscriber number common part, which has traditionally been stored redundantly, the subscriber number common part Depending on the degree of overlap, the effect is obtained in large numbers.

Claims (1)

[Claims] An input means for inputting a subscriber number, a subscriber number common part storage area for storing a subscriber number common part which is a common number between the subscriber numbers input by this input means, and a subscriber number non-common part storage area. It has a memory having a partial storage area, a control means for writing or reading a subscriber number into the memory, and a means for sending the subscriber number read from the memory to a communication exchange network, and has a common subscriber number. A subscriber number storage device characterized in that the part is stored as pointer data to the subscriber number common part storage area.
