Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a system, and an apparatus for charging traffic.

With the increasing maturity and popularization of internet applications and the demand of users for high-speed wireless access, home and abroad operators are developing broadband services vigorously, and how to effectively grasp and manage the user access situation in real time and carry out reasonable charging becomes an important issue.
At present, a Broadband Network Gateway (BNG) and an authorization and Accounting server (AAA) are mainly used in a Broadband user access technology to implement user traffic Accounting, and specifically, a time duration or month/year per package charging mode may be used, where the time duration-based charging is to charge a user according to the internet access time of the user, and the month/year per package charging mode is to charge a fixed fee to the user once per month/year. Or the user based on the flow accounting reports the user flow information to the AAA Server regularly through a Remote Authentication Dial In Service (RADIUS) protocol according to the flow generated by the Broadband Remote Access Server (BRAS) device according to the user internet Access Service, and the AAA Server generates the accounting information according to the accounting policy to perform accounting.
However, in the mainstream month/year packing manner, if the user uses network resources or only uses few network resources in one month/year, the user cannot enjoy preferential or reduced charges. In addition, a time length charging mode is adopted, the charging of the user is started after the user is connected with the network, the charging is stopped until the user actively puts the account down, and if the user forgets to put the account down after using the network, the time is always calculated, so that certain economic loss of the user is caused. If the statistical time interval of the periodically reported user flow information by the RADIUS protocol is large, the accuracy is not enough due to the charging delay, if the reporting interval is reduced, the AAA server and the BNG are frequently interacted, and due to the performance bottleneck of the AAA server, the problem of incomplete or repeated charging is often received, which causes charging errors, and in addition, the frequent reporting also excessively consumes BNG resources and performance, which affects normal services.
