As shown in FIG. 1, a subscriber terminal (eg, a laptop computer equipped with a cellular phone / wireless LAN, etc.) capable of IMT-2000 service 10 and a general purpose packet wireless service using the subscriber terminal 10 are provided. Gateway GPRS Support (GGSN) provided for connection with an external packet switching network such as a Serving GPRS Support Node (SGSN) that tracks the location of the subscriber station and performs an access function when a general packet radio service (GPRS) is applied. A GPRS support node (GSN) 20 having a Node) and an Internet Content Provider (ICP) is provided for the general purpose packet wireless service, and the SGSN and the GGSN are connected through a GPRS backbone. The physical link exists and is configured to transmit data with the charging gateway (CG) 100 described later by the GPT 'protocol, which is a GPRS tunneling protocol.

In addition, when using the data service using the subscriber terminal 10, the billing data generated from the packet network switching equipment (SGSN, GGSN) and the Internet content providing medium (ICP), that is, "S-CDR (SGSN generated-CDR), M- Mobility Management generated-CDR, CDR-SMO-CDR (SGSN delivered Short message Mobile Originated-CDR), S-SMT-CDR (SGSN delivered Short message Mobile Terminated-CDR), G-CDR (GGSN generated-CDR) And a billing gateway (CG) 100 for collecting and processing data of an IPDR (Internet Protocol Detail Record) and transmitting billing data in a processed packet form to the billing system 140.

The charging gateway 100, the receiver 112 for collecting the charging data generated from the GPRS support node (GSN) 20 in units of packets, inspects the packet information on the collected charging data, and verified Verification module unit 114 for transmitting the response data to the GSN 20 for the data as well as storing the charging data in the form of raw data in the memory DB 111, the response data and the GSN 20 A CDR collector (110) comprising a transmitter (116) for generating / transmitting request data for transmission to the network; Decoding / transmitting unit 122 for reading and decoding the billing data stored in the memory DB 111, determining whether the decoded billing data is duplicated / missing, integrated processing of the distributed billing data and filtering function A CDR processing unit 120 which is configured to perform hot billing and a format performing unit 124 for formatting the collected billing data; And an operation management unit (OAM) for performing processor management and monitoring, user security management, memory DB management, system management and monitoring, backup and restore functions, and statistical management required for collecting / processing / transmitting the charging data. 130 is configured to include.

The charging data processing method in the IMT-2000 system of the present invention configured as described above will be described with reference to FIGS. 1 to 4.

First, when using the IMT-2000 subscriber terminal 10 and using a call partner or a call service, or using the Internet service, providing the packet network switching equipment (SGSN, GGSN) and Internet content in accordance with the use of such data service In the medium (ICP), charge data set by a certain protocol is generated, that is, data of S-CDR, M-CDR, S-SMO-CDR, S-SMT-CDR and G-CDR of GGSN, and IPDR of ICP. In step 200, the CDR collecting unit 110 of the charging gateway 100 receives the packet by the GSN 20 and the GTP 'protocol (step 210).

Then, the charging data in the packet unit is transmitted to the verification module unit 114, and then the verification module unit 114, the version (Version) and information type (Information Type), value (Value), for each packet data Length and the like, and when a transmission request is generated according to the packet data verification result of the verification module unit 114, the sequence number and packet information of the charging data of the packet unit is raw data (raw). data) to be stored in the memory DB 111. However, if verification of the packet data fails, the corresponding response data is generated and transmitted to the GSN 20. In addition, the transmitter 116 generates response / request packet data for each message to be sent to the GSN 20 (see FIG. 3).

Meanwhile, the CDR processing unit 120 reads the charging data in the packet form stored in the memory DB 111 to determine whether the data is duplicated or missing, performs integrated processing of the distributed charging data, performs filtering and hot billing, and collects the collected data. A process for formatting the charging data in a predetermined form is performed (FIG. 2; step 220), and the processing thereof will be described with reference to FIG. 4.

First, the decoding / transmitting unit 122 reads the packet charging data stored in the memory DB 111 to perform ASN.1 decoding processing, and transmits the response data corresponding to the decoding result to the GSN 20 to provide the decoding processing result. In addition, the decoded packet charging data is converted from the format performing unit 124 into a data format of a predetermined format required by the charging system 140, and also packet data verification and distributed data integration according to a predetermined rule. Processing, filtering, hot billing processing and so on.

Here, the packet data verification checks 'Local Record Sequence Number' in the record for the decoded packet charging data and checks whether there is duplicate data or missing data among the collected charging data. In addition, verify the packet data by checking the allowable value and time stamp accuracy specified in the record field.

In addition, the distributed data generated in one call must be processed during S-CDR, M-CDR, and G-CDR processing from the packet switching network of SGSN and GGSN during the service usage, when such distributed data is generated. After checking the value of 'Record Sequence Number' and 'Cause for Record Closing' in the memory DB 111, the distributed data is integrated and processed as one record at the end of the generated call.

And, in using a variety of services using the IMT-2000 subscriber station 10, the network used according to the type of service is applied differently, the process of integrating the billing data collected from the SGSN, GGSN and ICP For example, for the S-CDR collected from SGSN and the G-CDR collected from GGSN, the billing ID and GGGSN address used fields are combined into one record, and the IPDR is processed. The correlation between ID address, service ID, URL, etc. of information and S-CDR of SGSN, G-CDR of GGSN, and IP address information is analyzed and integrated into one record.

The filtering process provides a function of removing unnecessary fields or records in each packet of packet data, or classifying by specific user or time zone, charging characteristics, and CDR types.

The hot billing process is to reduce the billing processing time by transmitting the billing data to the billing system 140 as soon as the service occurs only for a predefined hot billing customer without going through the normal billing route.

As described above, the billing data of which the series of processing is completed is then transmitted to the billing system by various methods such as real time transmission, automatic transmission, manual transmission, and scheduled transmission according to a registration cycle.

On the other hand, as shown in Figure 5, when the billing data generated in the SSGN, GGSN, ICP, etc. is transmitted to a series of processing and billing system 140, user security management through a graphical user interface (GUI), It performs functions necessary for process management and monitoring, DB management, system management and monitoring function, backup and restore function, statistics management, NMS / IF, and other operation management.

In other words, the user security management is that only a registered user can log in to the system, and a process management and monitoring function is provided to control or monitor all functions of collecting / processing / transmitting the charging data. do.

In addition, memory DB management allows you to register, change and delete information related to billing data processing through preset rules or reference tables, and system management and monitoring periodically manages system status to ensure safe system status. Keep it.

The backup data is periodically backed up to prepare for a failure, as well as processing various data and statistical data generated during billing data processing.

As described above, according to the packet data processing method in the IMT-2000 system of the present invention, the collection of various types of billing-related data generated according to a predetermined data service when using a predetermined subscriber station that supports the IMT-2000 service And by providing a data sharing process through a predetermined memory DB, the billing data processing speed can be improved, and the collection, inspection, integration, storage, and management of the billing-related data can be performed in a stable manner. And it is effective to provide a billing system with improved processing capacity.
