Detailed ways

The invention provides a content-based charging system and a method for realizing the charging, which is implemented based on flow analysis and provides a dynamic and static filtering condition management method. The so-called dynamic filtering condition management means that when the user is online, the rules applied by a certain user can also be modified at any time.

The billing system based on content billing supports the formulation of flexible content billing policies according to the individual needs of users; in addition, because it supports dynamic customization and modification of filter conditions according to users, the filter conditions are based on the collection of content billing information. According to the basis, the user's business characteristics can be expanded flexibly, such as QOS characteristics and security characteristics.

From the perspective of the scope of action, filter conditions can be divided into two types: one is global filter conditions; the other is filter conditions specific to a certain user, that is, user-level filter conditions.

User-level filter conditions take precedence over global filter conditions. When there is overlapping content in the two parts, the basis for flow analysis is based on user-level filter conditions. If user-level filter conditions conflict, which one to use is determined according to the priority Filtering conditions, the content-based charging system of the present invention can support two filtering conditions at the same time.

As shown in Figure 1, the billing implementation system of billing by content of the present invention includes:

The billing information collection system is used to collect billing information according to filter conditions and control business flow, including a stream analysis module 101, a filter condition management module 102, a filter condition management interface module 103, an authentication interface module 104, and a billing interface module 105 ;

The charging system, including the prepayment system 40 and the postpayment system 50, performs charging operations according to the charging information collected by the flow analysis module 101, and returns a charging response to the flow analysis module 101 to control the service flow.

Billing information collection system of the present invention comprises following module:

The flow analysis module 101 is used to analyze the service flow of the mobile terminal access data service according to the filter condition output by the filter condition management module, extract and output the service content characteristic code, service identification and service category information of the data service;

Specifically, the flow analysis module 101 analyzes the flow according to the filter conditions, sends the extracted service content feature code to the authentication server 30 through the authentication interface module 104 to authenticate the content, and simultaneously extracts the service identification and service category pass count corresponding to the filter conditions. The fee interface module 105 is sent to the prepayment system 40 or the postpayment system 50 for processing such as price approval and balance control;

A filter condition management module 102, configured to set, output and store filter conditions;

Specifically, the filter condition management module 102 is used to manage and maintain the filter conditions, and store a collection of filter conditions; the filter condition management module 102 can be configured on the PORTAL server, and can also be configured on the authentication server 30, the prepaid system 40 or the post-payment system. In the payment system 50; the PORTAL server in the mobile packet service network is a platform for mobile operators to display many services provided by ISP\ICP (service provider\content provider) to users, and it is also a platform for users to subscribe to services, query tariff information, and query accounts. Detailed self-service platform;

The filter condition management module 102 specifically includes the setting operation of the filter condition:

Set the network and transport layer parameters in the filter condition, including source IP (Internet Protocol) address, destination IP address, source port number, destination port number and protocol type, i.e. IP5 tuple;

Set the application layer parameters in the filter condition, including application protocol type and business content feature code;

Set the policy and charging control parameters in the filter conditions, including the identification of the corresponding service, service category, rate, priority, trigger action list, redirection address, QOS level and parameters, traffic threshold and time threshold, etc.

in:

The source/destination IP address is the source address/destination address in the IP packet header;

The source/destination port number is the source port/destination port in the IP packet header;

Protocol type, the protocol field in the IP packet header, indicating the transport layer protocol type, UDP or TCP;

Application protocol type, which indicates which application protocol characteristics are used to analyze the traffic matching the above source/destination IP address and source/destination port number source during traffic analysis;

Business content feature code, the information contained in the application protocol that can represent business content, for example, for http, url is one of its business content feature codes, but the service content feature code is not limited to this;

The identification of the service corresponding to the filter condition, a name of the service represented by the filter condition, which can contain a string of characters and numbers, and the name should be long enough to avoid repetition;

Business category is the classification of the business represented by the corresponding filter conditions. The basis of this classification can be the rate or other basis for convenient billing management;

Rates refer to different pricing strategies formulated for services according to traffic, time or times;

Priority, which indicates the priority of the filter conditions. In the case of multiple filter conditions conflicting, the rule with higher priority wins;

Authentication server 30 includes but is not limited to AAA (authentication, authentication and accounting) server, and can also be other systems that have the ability to authenticate users and the business content used by users;

The billing interface module 105 is used to send the service identification and service category of the authenticated data service output by the flow analysis module 101 to the billing system for billing processing;

Specifically, the billing interface module 105 interacts with the billing system (including the prepayment system 40 and the postpayment system 50), sends the prepaid billing request to the prepayment system 40, and hands over the postpaid bill information to the postpayment system 40. The payment system 50 accepts the charging response from the pre-payment system 40, converts it into an action instruction according to the content in the response and sends it to the flow analysis module 101, and the flow analysis module 101 further performs flow control and charging.

After the traffic generated by users accessing data services is filtered by the filter conditions, it can be judged whether service authentication is required, and then there is a billing process. This shows that the filter conditions are the basis for collecting charging information. After determining which service data flows need to be charged according to the filter conditions, it is still necessary to use these rules to determine which flows (IP 5-tuples, including) are associated with the data services. These When the flow starts, when it ends, and how much traffic occurs, and then report the billing information.

The specific workflow of the billing information collection system for billing according to the embodiment of the present invention will be described below in conjunction with Fig. 1 and Fig. 5; after the filter condition management module sets, stores and outputs the filter conditions for flow analysis and control, it includes Follow the steps below:

Step S601, the user sends IP packets for accessing data services, and these packets are sent to the flow analysis module 101 through Internet (Internet) gateway equipment (such as GGSN (General Packet Wireless Service Gateway Support Node)), and the flow analysis module 101 invokes the filter The condition management module 102 matches the IP 5-tuple information of the IP message and the network of the filter condition with the transport layer parameter;

Step S602, after the matching is successful, the flow analysis module 101 calls the filter condition management module 102, and performs protocol analysis according to the application protocol type to obtain the service content characteristic code of the agreement. If the application protocol type of the filter condition indicates that it is the HTTP protocol, the protocol analysis is Perform protocol analysis according to the HTTP protocol specification;

In step S603, the flow analysis module 101 matches the service content characteristic code obtained in step S602 with the service content characteristic code in the filter condition;

Through steps S601-S603, the flow analysis module completes the process of analyzing the service flow of the mobile terminal access data service according to the filter condition output by the filter condition management module.

Step S604, if the above matching is successful, the flow analysis module 101 obtains the service identifier and service category corresponding to the filtering conditions, and the flow analysis module 101 sends the service characteristic code to the authentication server 30 through the authentication interface module 104 for content authentication;

Step S605, during the user's access to the data service, the flow analysis module 101 periodically collects the IP 5-tuple, service identifier, service category and the relevant charging information (flow and duration) of the IP 5-tuple through the charging interface Module 105 sends the billing system (prepaid system 40 or postpaid system 50) to perform billing processing; the billing system returns a billing response message to the flow analysis module after processing.

Step S606, forwarding the IP message.

In this way, the charging system collects the charging information of content charging according to the filter condition.
