Fig. 2 is according to the flow chart of another embodiment of the flow statistical method based on application of the present invention.As shown in Figure 2:
In the time that operator wishes certain Video Applications A of user to carry out added flow charging, the attributive character of the application stream of application A is handed down to BRAS by radius accounting server.
Step 201, user accesses after BRAS, and BRAS is based on user's statistic flow.
Step 202, after user access, in normal user's charging flow, BRAS to radius accounting server, can be based on duration based accounting, based on charge on traffic or monthly payment charging with the traffic statistics information of radius message format report of user.
Step 203, in the time that user uses business A, the attributive character that BRAS flows by application detects the flow of application A, under user's statistic behavior, generates the stream mode of application A, and the flow information of statistics application A.
" business A " of the present invention, " application A " etc. use for convenience of description, can be any one business or application, there is no other special implication.
Step 204, when BRAS detects that business A finishes or when user's active break, completing user traffic statistics, and with the traffic statistics information of radius message format report of user to radius accounting server.Wherein, user's traffic statistics information comprises the traffic statistics information of applying A.
Operator, by the traffic statistics information of the application A that reports, carries out additional charges to application A flow.
The present invention has openly proposed a kind of flow statistical method based on application, defines application traffic Flow feature on BAS Broadband Access Server BRAS equipment, and the upper employing of BRAS nested structure is preserved User Status session and application stream mode flow simultaneously.
Utilize the extended attribute field in existing Radius agreement, increase Flow id field and one group of flow attribution, realize the nested attribute structure of user and application.Can realize the parallel charging based on User Status session and application stream flow.User, BRAS, Radius server can, based on this application subflow flow, be realized triggering, statistics and the end overall process of application traffic charging.
Flow statistical method based on application is compatible PPPoE and two kinds of access authentication scenes of IPoE simultaneously, realize the charge on traffic scheme based on application irrelevant with access technology.
Fig. 3 is according to nested status architecture and the mutual schematic diagram of Radius attribute message form of BRAS in an embodiment of the flow statistical method based on application of the present invention.As shown in Figure 3:
On BRAS equipment 31, adopt nested structure to preserve the application related information of user profile and specific needs charge on traffic.Session under each User Status, can and deposit multiple application stream flow.
Application traffic Flow feature, can define flexibly by attributes such as IP five-tuple, MAC Address, dscp fields.On BRAS equipment 31, can issue mode by static configuration mode or radius and obtain flow template.In the time receiving the user who meets template and flow, BRAS equipment 31 starts to generate stream mode.
BRAS equipment 31 reports in radius message increases stream Flow attribute, at least should comprise the attributes such as Flow ID, Flow-Attributes, Flow-Input-Octets and Flow-Output-Octets.Increase after attribute, message format changes two-dimensional format 33 into by original one dimension form 32.
On BRAS equipment 31, preserve the state flow of User Status session and user's application by regional model.According to regional model, offer in the Radius charging property message of Radius accounting server at BRAS equipment 31, increase the nested fields such as Flow ID.According to regional model feature, design the customer flow charging flow based on application, can and deposit with the traditional charge on traffic flow process based on user.
