Description

A Method for Realizing Dynamic Change of Internet Access Policy of Prepaid Users

technical field

The invention relates to the field of data communication, in particular to a method for realizing dynamic change of online strategy of prepaid users.

Background technique

In the current data communication, the standard RADIUS (Remote Authentication Dial In User Service) and its extension protocol are generally used for user online authentication and billing. A schematic diagram of the specific networking mode.

In Figure 1, Broadband Access Server (BAS), Authentication, Authorization and Accounting Server (AAA Server) and Portal Server (Portal Server) are connected together through the Internet. The user accesses the Internet through the BAS, and the AAA Server processes the authentication, authorization, billing and other processes required for the user to access the Internet. List (ACL) and other information. BAS and AAA Server both support the standard RADIUS protocol, and they can communicate according to the standard RADIUS protocol; Portal Server and BAS do not support the standard communication protocol, and the communication between the two can only be realized through the transfer of AAA Server.

According to the standard RADIUS protocol, after the user is authenticated, the AAA Server should estimate the user's available online time according to the user's balance information, and send the user's available online time to the BAS in the authentication passed message, so that the BAS can When the user's balance is insufficient, the connection between the user and the network can be cut off in time, so that the user's fee will not be overdrawn, which will damage the interests of the operator. However, the standard RADIUS extension protocol does not stipulate whether the AAA Server should estimate the available time for the user to surf the Internet under the new policy when the Internet access policy of the prepaid user is changed.

In the prior art, when the online policy of the prepaid user is changed, the AAA Server generally does not re-budget the user's available time under the new policy, and the specific process is shown in Figure 2. Fig. 2 is the flow chart of the method for changing the online strategy of prepaid users in the prior art, and this flow chart comprises the following steps:

Step 201: the prepaid user logs in to the Portal Server to select the Internet access strategy he needs, and the PortalServer sends the new strategy selected by the user to the AAA Server by changing the service request message (Change Service Req/A);

Step 202: AAA Server sends the new policy selected by the user to the BAS through an authorization change request message (CoA-Req) according to the standard RADIUS extension protocol;

Step 203: BAS revises the user's online strategy according to the received CoA-Req message, and after the online strategy is modified successfully, sends authorization change confirmation message (CoA-Ack) to AAA Server;

Step 204: The AAA Server receives the CoA-Ack message, and sends a change service request response message (Change Service Req/R) to the Portal Server.

For pre-paid users, different Internet access strategies are adopted, and the user Internet access rates are different. When the Internet access policy of a prepaid user is changed, the user’s Internet access policy is only modified on the BAS, and the AAA Server cannot distinguish which duration traffic is used under the old policy and which is used under the new policy in the subsequent billing. used below. AAA Server will not be able to settle the user's online status under the old policy, let alone budget for the user's online time under the new policy.

In the subsequent billing, the AAA Server can charge the prepaid users online according to the old policy, and can also charge the prepaid users online according to the new policy. When the AAA Server charges prepaid users online according to the old policy, if the rate of the new policy of the user is higher than that of the old policy, the interests of the operator will inevitably be damaged; similarly, if the rate of the new policy of the user The rate is lower than the rate of the old strategy, and the interests of users will also be damaged. When the subsequent billing of the AAA Server charges the prepaid user for Internet access according to the new policy rate, the situation is opposite. In short, no matter which rate AAA Server charges, as long as the user's online strategy changes, the interests of one party will always be damaged.

Contents of the invention

The step B further includes: the authentication, authorization and accounting server receives the authorization change confirmation message, and sends a service change request response message to the portal website. The sending of the user's access to the Internet according to the old policy to the authentication, authorization, and accounting server described in step B is: after the broadband access server sends the authorization change confirmation message to the authentication, authorization, and accounting server, immediately carry the user's access to the Internet according to the old policy. It is sent to the authentication authorization accounting server in the intermediate accounting message. The situation that the user surfs the Internet according to the old strategy at least includes the user's online duration and traffic information according to the old strategy.

In the above solution, the authentication, authorization and accounting server described in step C sends the user’s available time length to the broadband access server as follows: the authentication, authorization and accounting server carries the user’s available time length in the authorization change request message and sends it to the broadband access server. server. After step C, the method further includes: the broadband access server receives an authorization change request message, and sends an authorization change confirmation message to the authentication, authorization and accounting server.

Therefore, the method for realizing the dynamic change of the online strategy of prepaid users provided by the present invention is to report the information such as the user's online time and traffic according to the old strategy to the AAA Server immediately after the user changes the online strategy by the BAS, so that the AAA Server can Settle the user fee in time according to the rate of the old policy, then re-budget the user's available time according to the new policy rate and the user's balance at this time, and send the user's available time to BAS. With the present invention, after the user changes the Internet access strategy, the BAS can reasonably control the user's online access according to the AAA Server's rate of the new strategy and the user's balance at this time. the goal of. In addition, the present invention can use standard RADIUS messages to communicate between the AAA Server and the BAS, which is beneficial to the cooperative use between the AAA Server and the BAS produced by different manufacturers.
