Abstract

The present invention relates to a differential charging system and method for each content of an upper limit rate service in a wideband code division mobile communication (WCDMA) data service.

The WCDMA data service uses a charging method using APN information, and thus, it is impossible to accurately charge packets in real time for differential charging for each packet content, and it is impossible to control the last call of the upper limit subscriber.

In the present invention, the WCDMA capping scheme of the charge rate service is interlocked with the Internet Usage Extractor (IUX), the Internet Protocol Mediation System (IPMS), and the UDA (Usage Data Aggregator), and the CAP protocol interworking between SGSN and SCP (Service Control) In this paper, a differential packet charging system and method for WCDMA capping service contents capable of accurate packet real-time data charging and last call control in differential charging for packet contents for subscribers of capping service plans are presented.

The present invention relates to a differential charging system and method for each content of an upper limit rate service in a mobile communication (WCDMA) data service of a wideband code division multiple access method. More specifically, the charge for the WCDMA capping service is not based on the total packet volume of the data used using the APN (Access Point Name), and various contents included in the packet volume are analyzed to determine Accordingly, the present invention relates to a system for calculating billing and a method thereof.

In general, the upper limit rate service of the WCDMA data service is charged based on the amount of used packets by using APN (Access Point Name) information. Looking at the structure of the usage data for the WCDMA data service, the packet information is composed of various contents such as text, small-capacity multimedia, large-capacity multimedia, and wireless Internet access, and the rate applied to each content is determined differently.

1 is a schematic configuration diagram of a charging system based on a packet amount of a conventional WCDMA upper limit rate service. The mobile communication terminal 10, which is used as an upper limit service of the WCDMA data service, a radio base station (RTS) 20 for performing communication between the mobile communication terminal 10 and the radio station, and controls a plurality of radio base stations A base station controller (RNC) 30 for supporting voice / data communication, an exchanger (MSC) 40 that is responsible for mobility management and voice call processing for circuit mode service subscribers, As a serving node of a home location register (HLR) 50 that stores all information about the mobile communication terminal 10 and a GPRS (General Packet Radio Service) providing packet service directly to the mobile communication terminal 10, By setting the mobility management context for the packet mode for the mobile communication terminal 10, a Serving GPRS Support Node (SGSN) 60 for performing management of the packet mode data service of the mobile communication terminal 10, and a packet data net A gateway GPRS support node (GGSN) 70 which performs tunneling and IP routing functions by maintaining routing information to the SGSN 60 as a GPRS gateway node directly connected to a network or the Internet, and the SGSN 60 or A billing gateway (CG) 80 for delivering billing data including the APN information field and packet amount from the GGSN 70 to the billing device, and the SGSN 60 and the CAP protocol interworked with the call control function and the capping fee SCP 90 and the billing gateway CG 80 for receiving packet billing information of the packet and receiving packet billing information (UDR) from the billing gateway (CG) 80.

Wow, said customer It comprises a customer information distribution system (CDS) 120 for receiving the customer information from the integrated information system (COIS) 110 to distribute to the home location register (HLR) 50, SCP (90), Signaling of the data call of the WCDMA capping service subscriber is to allow the SGSN 60 to perform the call processing and billing function of the time or data amount base by signaling through the CAP protocol interworking with the SCP 90 have.

However, in the packet-based billing system and method for the subscriber of the maximum rate plan of the WCDMA data service, although the signaling and call control function of the SGSN 60 can normally process the billing by the packet unit, it performs differential charging for each packet content. There is a problem in that it is impossible to control the accurate packet real-time charging and the last call of the subscriber of the upper limit plan due to the differential charging for each packet content because there is no function to do it.

The present invention is to solve the problems of the prior art, an object of the present invention is the content-based differential that can perform accurate real-time call processing and the last call control for the differential charges per packet content for the maximum rate service of the WCDMA data service To provide a billing system and method thereof.

As a technical idea for achieving the object of the present invention, in the present invention, the billing method of the WCDMA capping service and the Internet Usage Extractor (IUX), Internet Protocol Mediation System (IPMS) and UDA (Usage Data Aggregator) In this paper, differential charging system and method for WCDMA capping service contents that can control accurate packet real-time data and capturing the last call through capturing SGSN and SCP (Service Control) CAP protocol are presented.
