How to output subscriber number by station number of communication system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber number output method of a communication system. Particularly, when a subscriber's registration information for each station number is required in a communication system, a combination of bytes and bits rather than character data handling is performed. The present invention relates to a method of outputting a subscriber number for each station number in a communication system that can effectively represent subscriber registration information.

Accordingly, the present invention provides a large amount of data ('0000' to '9999') when a subscriber wants to know a specific subscriber's status or a registered subscriber's status, or a service's subscriber status, by a demand of a vast operator. In this case, I want to suggest how to send a lot of data efficiently.

Generally, a code division multiple access (CDMA) scheme or the like is used as a communication system, and there are a digital cellular system and a personal communication system (PCS).

1 is a block diagram of a general communication system.

As shown in the figure, an exchanger 1 for transmitting a call processing request of a terminal to another communication network such as a public telephone switching network through a public network or a dedicated network so that a communication service can be made; A home location register (HLR) 2 which is connected to the switch 1 and manages a subscriber's basic information (including location information) and additional service information in a database; A control station (3) for transmitting / receiving messages with the exchange (1); A base station (4) for transmitting a call transfer request from the control station (3) to a terminal (5) and receiving a call processing request from the terminal (5); It is composed of a terminal (5) for receiving a communication service to the subscriber in the coverage area of the base station (4).

In the general communication system configured as described above, when the subscriber intends to use the communication service while having the terminal 5 within the coverage area of the base station 4, the control station 3 controls the base station 4 to determine the subscriber. The terminal 5 transmits the information to the home location register 2 through the exchange 1. In addition, the communication system operates to perform a voice information service according to a request of the terminal 5 or to connect to another communication network to perform a communication service.

In such a communication system, the home location register (2) must be used in the mobile network. The contents related to the processing of the subscriber registration number for each station number generated by the operator's request. It requires a command to view contents such as subscriber registration status by service. In the processing of such a command, the subscriber's registration information is transmitted from the main computer to the operator's computer. For example, the command showing the subscriber status registered in a specific station number is as follows.

The maximum number of subscribers that can be registered in one station number is 10,000 people from '0000' to '9999'. The method of storing 4 digits in the buffer is as follows. If buf [0] = '1', buf [1] = '2', buf [2] = '3', buf [3] = '4'.

In the second method, when the subscriber number to be stored is '1234', it is stored as a hexadecimal character (Hexa_character) such as buf [0] = 0x12 and buf [1] = ox34.

In both cases, a mode-sized buffer is required, requiring up to 40,000 bytes and 20,000 bytes, respectively, to accommodate all 10,000 subscribers.

However, even in the case of using the hexadecimal character, 20,000 bytes are required. Since the size of the buffer used by the actual home position registration system 2 does not exceed 2,048 bytes, the conventional method registers subscribers by station number according to the operator's request. There was a problem with unknown status.

Accordingly, the present invention has been proposed to solve the above conventional problems, and an object of the present invention is to provide a subscriber number using a matrix relationship between bytes and bits of a buffer when registration information of a subscriber for each station is required in a communication system. By accommodating four digits at the end of the present invention, there is provided a method for outputting a subscriber number for each station number in a communication system that can improve subscriber number processing without being limited in data size.

In order to achieve the above object, the subscriber number output method for each station of the communication system according to the present invention,

If the subscriber's registration information is needed for each station number, find the corresponding station number, read the subscriber number registered in the corresponding station number, initialize the buffer to store the subscriber number, and place the 4 digits at the end of the subscriber number in the matrix relationship between the byte and the bit of the buffer. Storing the subscriber number in the buffer by using a feature of the technical configuration.

Hereinafter, with reference to the accompanying drawings an embodiment according to the technical idea of the subscriber number output method for each station number of the present invention as described above in detail.

In order to solve the conventional problem, a 4-digit processing method is used at the subscriber end using the matrix relationship between the byte and the bit of the buffer, which accommodates 4 digits at the end of the registered subscriber number for each 8 station numbers in 1 byte. To do that.

FIG. 2 is a matrix structure diagram representing a subscriber number of a specific station number using a bit operation applied by the present invention. For example, it is assumed that two subscribers, '8500005' and '8501234', are registered in the '850' station number. Shows the value stored in the buffer.

Thus, the four digits at the end of the subscriber number are '0005' and '1234', respectively, which are divided by eight to store eight in one byte. In the case of '0005', the quotient is '0', the rest is '5', and in the case of '1234', the quotient is '154' and the remainder is '2'.

If this is expressed as a matrix, '0005' is represented by the fifth column of the first matrix (first byte-fifth bit of buf [0]), and '1234' is represented by the second column of the 155th row (155th byte- 2nd bit of buf [155]). In this way, all numbers from '0000' to '9999' can be represented by a matrix of 1250 * 8.

3 is a flowchart illustrating a method for outputting a subscriber number for each station number in a communication system according to the present invention.

As shown in the drawing, when registration information of a subscriber for each station number is required, a first step (ST1 to ST3) of finding a corresponding station number, reading a subscriber number registered in the corresponding station number, and initializing a buffer for storing the subscriber number; A second step (ST4 to ST9) of storing the subscriber number in the buffer is performed by using the matrix relationship between the byte and the bit of the buffer at the end of the subscriber number.

Wherein the second step (ST4 ~ ST9), the step of obtaining the quotient and remainder by dividing the four digits by eight at the end of the subscriber number (ST4 ~ ST6); The quotient is used to determine the byte position of the buffer to determine the row, and the remainder is used to determine the bit position of the buffer to determine the column, whereby the position of the row and column of the buffer determined by the bit operation is determined. Store the subscriber number (ST7 ~ ST9).

The following is an example for sending 8 subscribers to a byte for registration of a subscriber for a station number.

For example, the processing procedure for outputting all subscribers registered in station number '850' is as follows.

First, it is assumed that subscriber number '8501234' is registered in station number '850'.

Then, the station number '850' is first found (ST1), and the subscriber number registered in the station number '850' is imported (ST2). It can accommodate up to 10,000 subscribers. The buffer 1250 bytes is stored as '0' and initialized (ST3).

Therefore, it searches for whether a subscriber corresponding to the directory number (DN) exists and repeats the search.

Accordingly, the number 1234 which is the last four digits of the number 8501234 found in the subscriber table is divided by eight.

1234/8 = quotient: 154, remainder: 2

Accordingly, the row and column positions of the subscriber number '8501234' are determined. The row is determined by the 155th byte, and the column is determined by the second bit. The buffer is stored at buf [154].

Then use the bit operation to fill the second bit of the 155th byte (buf [154]) with '1'.

buf [154] = buf [154] | 0x40;

As such, the present invention is able to represent all subscribers (10,000 subscribers) using a small buffer (1250 bytes) to display information about all subscribers registered in a particular station number.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. That is, the present invention can be used to register or unregistered subscriber output by station number, subscriber output by additional services, and the like. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the subscriber number output method for each station number in the communication system according to the present invention has the same effect even when only 1,250 bytes are used for an operation requiring at least 20,000 bytes in a system limited by data size. It can be shown that there is an effect that brings about 4 to 8 times the improvement in processing capacity compared with the prior art.

In addition, the present invention also has an effect that can be applied to the data processing field by using the data processing of the bit unit rather than the data processing of the character unit.
