Hereinafter, the first step S1 described above with reference to FIG. 3 will be described in more detail.

First, the MCC 101 determines whether a call has been attempted (S1-1).

At this time, if the call is not attempted in the first step S1-1 (NO), the MCC 101 proceeds to the first first step S1-1 again, while if the call is attempted (YES). The MCC 101 performs a call processing operation corresponding to the call (S1-2).

Thereafter, the MCC 101 determines whether the call has ended (S1-3).

At this time, if the call does not end in the first 1-3 steps (S1-3) (NO), the MCC 101 proceeds to the first 1-2 steps (S1-2) again, while the call ends (YES). The MCC 101 generates charging data associated with the call according to the defined standard with the CDGM 102 (S1-4). Here, generating the charging data associated with the call according to the defined standard with the CDGM 102 means that data types such as the array type, the BCD type, the calling number, the called number, the call start time, The type of data, such as call end time, is determined according to the defined specification.

Subsequently, the MCC 101 transmits the charging data generated according to the defined standard with the CDGM 102 to the CDGM 102 and proceeds to step 1-1 (S1-1) (S1). -5).

Then, the CDGM 102 in the ASP 100 receives and compresses the charging data transmitted from the MCC 101 and transmits the compressed data to the CDR 201 in the OMP 200 (S2).

Hereinafter, the second step S2 described above with reference to FIG. 4 will be described in more detail.

First, the CDGM 102 receives the charging data transmitted from the MCC 101 and processes the data into a data form required by the charging collection center 1 (S2-1). Here, the data type required by the billing collection center 1 means a form in which an arrangement order for information such as call origination, called party, call start time and call end time is defined.

Thereafter, the CDGM 102 compresses the charging data in which the processing procedure is performed (S2-2). At this time, the method of compressing the billing data may use a compression method suitable for billing data from among known compression methods.

Subsequently, the CDGM 102 transmits the compressed charging data to the CDR 201 in the OMP 200 and proceeds to step 2-1 (S2-1) (S2-3).

Then, the CDR 201 receives the compressed charging data transmitted from the CDGM 102 in the ASP 100 and stores it in the charging disk 300 and the charging magnetic tape 400 (S3).

Hereinafter, the third step S3 described above with reference to FIG. 5 will be described in more detail.

First, the CDR 201 in the OMP 200 creates a first buffer and a second buffer in the memory 203 and initializes the first buffer and the second buffer (S3-1).

Thereafter, the CDR 201 temporarily receives the compressed charging data transmitted from the CDGM 102 and temporarily stores it in the second buffer (S3-2).

Subsequently, the CDR 201 determines whether the sum of the charging data sizes stored in the first buffer and the second buffer is larger than 1K byte which is a charging disk storage unit, that is, a charging block unit (S3-3). ).

In this case, when the sum of the charge data sizes stored in the first buffer and the second buffer is greater than the charge disk storage unit, that is, the charge block (YES) in step 3-3 (S3-3), the CDR 201 After charging data stored in the first buffer is read and stored in the charging disk 300 (S3-4).

Thereafter, the CDR S201 clears the first buffer and reads the charging data stored in the second buffer to store the charging data in the first buffer (S3-5).

Subsequently, the CDR 201 determines whether or not the number of charge blocks stored in the charging magnetic tape 400 can be stored in the charging magnetic tape 400 among the charging data stored in the charging disk 300 ( S3-6).

If the number of charge blocks not included in the billing magnetic tape 400 in the 3-6 step (S3-6) is not the number that can be stored in the billing magnetic tape 400 (NO), the CDR 201 is the third. In step S3-2, if the number of charge blocks not recorded in the charge magnetic tape 400 is the number that can be stored in the charge magnetic tape 400 (YES), the CDR 201 blocks the charge block. After storing to the charging magnetic tape 400, the process proceeds to step 3-2 (S3-2) (S3-7).

On the other hand, if the sum of the billing data sizes stored in the first buffer and the second buffer in step 3-3 is less than the billing disk storage unit, that is, the billing block (NO), the CDR 201 ) Reads the latest compressed charging data stored in the second buffer and stores the latest compressed charging data in the first buffer, and then proceeds to step 3-2 (S3-2).

Meanwhile, after the third step S3, the CDSB 202 reads the billing data block requested by the billing collection center 1 from the billing disk 300 and transmits the billing data block to the billing collection center 1. (S4).

Hereinafter, the fourth step S4 described above with reference to FIG. 6 will be described in more detail.

At this time, if the charging data transmission request signal is not received from the charging collection center 1 in step 4-1 (S4-1) (NO), the CDSB 202 performs step 4-1 (S4-1). On the other hand, when the charging data transmission request signal is received from the charging collection center 1 (YES), the CDSB 202 receives the charging data block start number and end number included in the charging data transmission request signal. By checking, the charging data blocks requested by the charging collection center 1 are identified (S4-2).

Thereafter, the CDSB 202 checks whether all of the billing data blocks requested by the billing collection center 1 exist in the billing disk 300 (S4-3).

If the charging data blocks requested by the charging collection center 1 are not present in the charging disk 300 in step 4-3 (NO) (NO), the CDSB 202 is configured to perform the fourth 4-step. Proceeding to step 1 (S4-1), if the charging data blocks requested by the charging collection center 1 are all present in the charging disk 300 (YES), the CDSB 202 performs the compressed charging data. Blocks are read from the charging disk 300 (S4-4).

Subsequently, the CDSB 202 transmits the compressed billing data blocks requested by the billing collection center 1 to the OMID 500. Then, the OMID 500 receives the charging data blocks transmitted from the CDSB 202 and transmits the charging data blocks to the charging collection center 1 through the TCP / IP transmission method (S4-5).

As described above, according to the charging data transmission method in the mobile communication switch according to the present invention, the charging data generated at the end of a call is compressed, stored in a charging disk, managed, and transmitted to the charging collection center. By reducing the number of charge data reads / writes to the charge disk when the charge data is maintained and managed, the OMP load is reduced, and the transfer speed can be improved when the charge data is transmitted.
