Method and apparatus for collecting charging information of a data service


The present invention discloses a charging method for collecting charging information of data service and an apparatus thereof. The method comprises: receiving service data from a gateway service node; determining a protocol type of the received service data according to an IP port number of the service data; classifying the received service data according to the protocol type of the service data; distributing the classified service data to a plurality of protocol processing modules; at each of the plurality of protocol processing modules, extracting charging information of the classified service data, wherein the charging information comprises the protocol type of the service data; sending the charging information to a charging system for charging by a charging mode; and transmitting the respective classified service data transparently to a packet switched domain network. This invention can accurately collect the charging information of service data of various classes.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 11/414,476, filed Apr. 28, 2006, which is a continuation of International Patent Application No. PCT/CN2004/001224, filed Oct. 28, 2004. The International Application claims priority to pending Chinese Patent Application No. 200310103313.1, filed Oct. 28, 2003. The afore-mentioned patent applications are hereby incorporated by reference in their entireties.

TECHNICAL FIELD

The present invention relates to techniques for collecting charging information of a packet data service in a wireless network, and particularly, to an apparatus for collecting charging information of a packet data service and charging method thereof.

BACKGROUND

Wireless networks, with their fast development, are available to provide data services based on a packet-based network. The integration of a wireless packet-based network and an Internet has formed a good foundation for the development of wireless data services. At the same time, the traditional mode of service charging in the wireless network, such as charging the voice service based on time duration, can no longer satisfy the demand of data services. Therefore, the charging mode of data service has become a focus in the technical field.

The charging modes of data services include volume based charging mode, content based charging mode, application based charging mode, and time-duration based charging mode. For example, Multimedia Messaging Service (MMS) is charged by content, i.e., charged by each piece of message regardless of volume of flow. For another example, stream media video service may be charged according to the actual volume of flow, or charged by content as well.

At present, collecting points of charging information generally involve various devices, including Serving GPRS Support Nodes (SGSN), Gateway GPRS Support Nodes (GGSN), Wireless Access Protocol Gateways (WAP GW), and service servers. Typically, the volume charging information of a service is collected at the SGSN or the GGSN and it is sent to a Service Control Point (SCP) or other charging devices for cost deductions and terminal charges, while the content, application or time duration charging information is collected at the service servers and is sent to the SCP or other charging devices for cost deductions and terminal charges.

SUMMARY

The present invention is directly toward to an apparatus applied in a wireless network for collecting charging information of a data service, comprising: a protocol distribution processing module for classifying service data received from a gateway service node in the wireless network by protocol type, and sending the classified service data to a protocol processing module of the corresponding protocol type; receiving service data from one or more than one protocol processing module and sending the service data to the gateway service node;

said one or more than one protocol processing module for receiving the classified service data from the protocol distribution processing module corresponding to the protocol type, obtaining charging information of the service data and sending the charging information to a charging system, and transmitting the service data transparently to a packet switched domain network; receiving the service data from a packet switched domain network, obtaining the charging information of the service data and sending the charging information to the charging system, and transmitting the service data transparently to the protocol distribution processing module.

Meanwhile, the present invention also provides a charging method for data service in a wireless network, comprising:

A. deciding protocol type of received service data, and classifying the received service data in terms of the protocol type of the service data; and B. obtaining charging information of the received service data having been classified, respectively, and sending the obtained charging information to a charging system for charging.

As can be seen from the above, according to the present invention, an apparatus for collecting charging information of data service is added between the GGSN and the packet-based network. The charging information being collected comprises all information of volume, content, time duration and application charging mode of the service data, such as the volume and time duration of the data service and the service class of the service data. The collecting apparatus of charging information of a data service classifies the service data according to the protocol type thereof, processes the service data of different protocol types in different protocol processing modules, obtains Charging Data Record (CDR) information of different service data for charging, and charges the corresponding data service in a prepaid charging system or a real-time charging system based on the CDR information. Therefore, the apparatus and method of this invention can implement a uniform collection of the charging information of data services so as to send the information to the charging system for charging in corresponding charging modes.

As the charging information collected by the apparatus of the present invention comprises the service class of the service data, even if the charging system has charged the service data based on the content charging information collected by other service servers, the charging system can still differentiate the service class of the service data and recognize the service data based on the charging information collected by the apparatus of this invention, and thus no more charging will be done. Consequently, the problem of repeated charging on the existing wireless networks can also be solved by this invention.
