Abstract

PURPOSE: A method for controlling charging data of a mobile communication exchange is provided to store or transmit charging data as a sub file unit. CONSTITUTION: A charging block(10) detects whether a storing request signal requesting a charging data storage is received. If so, the charging block(10) attempts an opening of a charging file, and opens the charging file. When the charging file is opened, the charging block(10) accesses to a corresponding sub file, and stores the charging data as a sub file unit. If the charging file is not opened, the charging block(10) attempts a generation of a new charging file. If the new charging file is generated, the charging block(10) stores the generated charging data as a sub file unit. The charging block(10) confirms whether a transmission request signal transmitting the sub file to a charging center(14) is received. If so, the charging block(10) attempts an opening of the charging file. If the charging file is opened, the charging block(10) accesses to the charging file, and transmits a corresponding sub file to the charging center(14).

Processor (hereinafter referred to as " OMP "), and the like, each processor performs an assigned unique role to realize communication of the mobile station.

On the other hand, the charging file in the exchange is generated in the CDR (Charging Data Recode: Charging Data Record: " CDR ") 11 as shown in Fig. 1, and the Charging Data Send Block: Charging Data. Transmission block: hereinafter referred to as "CDSB" 13 is transmitted to the charging center (14).

In other words, in the case of storing the charging data in the charging disk 12, 10 charging data are configured and stored in one record through the CDR 11, and the charging data is transmitted to the charging center 14. In this case, a header was assigned to each record and transmitted.

However, the conventional billing data control method as described above has a problem that transmission efficiency and sub-file access efficiency are deteriorated by storing and transmitting billing data in a record unit having 10 billing data as one.

Therefore, the present invention has been proposed to solve the above problems of the prior art,

An object of the present invention is to store and transmit the billing data in a billing disk in a unit of one subfile with 100 records, thereby improving the access efficiency when accessing the corresponding subfile in the billing block and simultaneously transferring billing data. The present invention provides a charging data control method of a mobile communication switch that can improve efficiency.

Hereinafter, a preferred embodiment of the present invention according to the technical spirit as described above will be described in detail with reference to the accompanying drawings.

In the case where the charging data is to be stored first, as shown in FIG. Continuously detect whether or not a storage request signal to be stored in the file has been received.

In this case, when it is determined that the storage request signal is detected in the storage request detection step 110, the charging file opening attempt step 120 is attempted to open the charging file by attempting to open the corresponding charging file.

When it is determined that the charging file is opened as a result of performing the charging file opening attempt step 120, the first storage processing step 130 for storing the charging data by accessing the corresponding subfile of the opened charging file is performed. do. On the other hand, if it is determined that the billing file has not been opened, if a new billing file is opened and a new billing file is opened, the 8400 subfiles constituting the open billing file are initialized, If the charging data is stored and the opening of the new charging file fails, the second storage processing step 140 for outputting the failure result is performed to store the charging data in sub-file units or to output the storage failure result.

Next, as is well known, the process of transmitting the billing data to the billing center in the state of storing the billing data in the unit of a subfile is as follows.

First, as shown in FIG. 4, by performing the transmission request signal detecting step 210, the storage request signal for transmitting the corresponding subfile in the charging file to the charging center in the charging block 10 in the mobile communication exchange is displayed. Continuously detect whether or not received.

In this case, when it is determined that the transmission request signal is detected in the transmission request detection step 210, the transmission processing step 230 of accessing the open charging file and transmitting the corresponding subfile to the charging center 14 is performed. If it is determined that the billing file is not open, the failure result output step 240 is performed to output the failure result.

In other words, in transmitting billing data, the unit of data transmission is performed in the sub-file unit, thereby reducing the transmission amount by reducing the number of bits representing the header and improving the transmission efficiency by reducing the transmission delay time due to frequent transmission. Will be.

In other words, in today's situation where the amount of information is increased, the transmission path is high, and the system to process the data is processed at too small a unit regardless of the system's capability and information volume, the system is inefficient. This results in operation.

For example, when a billing data is to be transmitted in a subfile unit having 100 records as one subfile, one header is used. However, when billing data is transmitted in a record unit, billing data as much as the subfile is transferred. To transmit, 100 headers are required, and in order to store each billing data in record units, the number of bits and time required for addressing or storage control are used more than in the case of subfile units.

The above-described "billing data control method of the mobile communication exchange" of the present invention, when storing or transmitting the charging data, by storing or transmitting in the unit of a subfile, thereby improving access efficiency when accessing the corresponding subfile in the charging block There is an effect that can improve the transmission efficiency of the charging data.
