Description

A business billing method and system, and an intelligent matching module

technical field

The invention relates to service charging technology in the field of mobile communication, in particular to a service charging method and system, and an intelligent matching module.

Background technique

With the rapid development of mobile communication today, the use of General Packet Radio Service (GPRS) has shown explosive growth. Facing the situation that different users have different application requirements, it is possible to formulate differentiated billing strategies for different applications. It covers a wider range of users and realizes value-added services. At the same time, it also adapts to the development trend of future wireless data services.

One of the most important functions of the gateway GPRS support node (GGSN) is to perform content billing. By distinguishing different business content, when users use different data services, different rates are implemented correspondingly.

In the existing network, GGSN implements content charging by dismantling and analyzing GPRS uplink and downlink service data.

The content charging process for uplink service data is shown in Figure 1, which mainly includes the following steps:

Step 101, GGSN decapsulates the received data packet, analyzes whether the decapsulated data packet corresponds to an existing flow, if yes, executes step 105; if not, executes step 102;

The existing flow refers to an existing record, which includes Internet access IP, business category, billing type, etc.; the Internet access IP is carried in the service data, and flow matching can be performed through the Internet access IP;

Step 102, the GGSN continues to match the rules according to the network layer or transport layer identification of the service data, if the corresponding network layer or transport layer rules are matched, execute step 103; otherwise, execute step 106;

Steps 103-104, continue to analyze the service data, match the corresponding application layer rules, and create a flow for the data packet, which corresponds to the service category and charging type;

Said creating a stream for the data packet refers to creating a record for the data packet, and inserting the corresponding Internet access IP, service category and billing type in the record;

Step 105, generate a call list (CDR, Call Detail Record) according to corresponding rules;

If step 105 is executed after step 101, said generation of bills according to corresponding rules refers to generating bills according to the billing type recorded in the flow matched in step 101; if step 105 is executed after step 104 , said generating bills according to corresponding rules refers to generating bills according to the billing type recorded in the flow created in step 104;

In step 106, the matching rule fails at the network layer or the transport layer, and a CDR is generated according to the default rule (ordinary traffic).

Finally, the GGSN sends the decapsulated service data to the public data network (PDN).

The content charging process for downlink service data is shown in Figure 2, which mainly includes the following steps:

Step 201, after the GGSN receives the data packet from the PDN, it performs rule matching according to the network layer, the transport layer, and the application layer, and if the matching is successful, execute step 202; otherwise, execute step 203;

Step 202, matching the corresponding network layer or transport layer rules and application layer rules, and generating a CDR according to the matched rules;

Step 203, if no corresponding network layer or transport layer rules and application layer rules are matched, a CDR is generated according to the default rules (ordinary traffic).

Under normal circumstances, when a user uses a specific data service, it needs to be charged in conjunction with the charging rules of the specific service; when the corresponding charging rule cannot be matched, the data service used by the user will generate a common traffic bill, resulting in an exception Billing. For example: due to the popularity of smart terminals, many low-end smart phones do not fully comply with the protocol specifications when they are produced. When such terminals use GPRS services, there will be various abnormal messages after releasing the GPRS connection. According to the current The content matching rules cannot match the content and will be billed according to ordinary traffic; another example: due to the unstable performance of some service provider (SP, ServiceProvider) servers, it is very easy to cause the user's GPRS connection to be interrupted abnormally. Due to the network delay, this part of the data traffic cannot be billed for content matching and is billed for ordinary traffic. For example, the user only accesses the newsletter service. When the user requests to go offline (close the service), there is data for unknown reasons. Packets are sent from the network side to the user terminal, and since the user has closed the connection, this part of the data packets will be billed as normal traffic.

It can be seen that, in the prior art, the traffic charging method for the GPRS service often has the problem of inaccurate charging.

The content charging means that according to the service category used by the user, the corresponding charging type is used for charging.

In conjunction with Fig. 3, Fig. 3 is a schematic flow chart of a charging method for a service according to an embodiment of the present invention. When the GGSN receives a data packet, the GGSN copies the data packet to the intelligent matching module; The content charging matching is performed on the service data of the business data. If the matching is successfully completed, the content charging will be carried out according to the matching rules, and the corresponding charging information (that is, the bill) will be generated. If the content charging matching fails, the GGSN will pass through the smart matching module. The message interface between them provides the user information of the business data that failed to match to the smart matching module; the smart matching module searches for the business data of the corresponding user from the data package saved by itself according to the user information of the business data that fails to match provided by the GGSN , and perform charging rule matching (secondary matching) by analyzing the service data (analyzing the user service establishment and ending process) to generate corresponding charging information (content charging information or general charging information).
