An ipv4/ipv6 dual-stack user billing method and device

Abstract

The present invention relates to the field of communications. Provided in an embodiment of the present invention are an Ipv4 / Ipv6 double-stack user billing method and device, for reducing the message exchange between BRAS and an existing backstage AAA server, and reducing the impact on the backstage AAA server. The Ipv4 / Ipv6 double-stack user billing method comprises: establishing an Ipv4 connection for an Ipv4 / Ipv6 double-stack user, and generating a billing request packet; establishing an Ipv6 connection for the Ipv4 / Ipv6 double-stack user, generating a billing update packet, and completing the access connection of the pv4 / Ipv6 double-stack user; expanding the existing fields of the billing request packet; summarizing the double-stack information of the billing request packet and the billing update packet, inserting the summarized double-stack information into the expanded billing request packet to form a new billing request packet, and transmitting the new billing request packet. The embodiment of the present invention is used for billing Ipv4 / Ipv6 double-stack users.

Description

technical field [0001] The invention relates to the communication field, in particular to an Ipv4 / Ipv6 dual-stack user charging method and device. Background technique [0002] In the existing telecommunication network, before the access user goes online, the user access management system (Broadband remote access server, BRAS) will perform background AAA server (Authentication, authorization, accounting, AAA) authentication, authorization and accounting for the access user . [0003] In the authentication phase of the user, the BRAS will send an authentication request message to the background AAA server. The background AAA server will authenticate and authorize the user's username and password. Then, the background AAA server will return an authentication response message to the BRAS, carrying the user's authentication Result and authorization information; when the Ipv4 / Ipv6 dual-stack user successfully establishes a link connection, the BRAS sends an accounting message of...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the above-mentioned technical solution, the inventor found that there are at least the following problems in the prior art: at present, the background AAA server is already heavily loaded in the existing IPv4 single-stack network, and the exchange of multiple billing messages has a negative effect on the background The AAA server has a serious impact. Since the interval between the IPv4 / IPv6 dual-stack connection and access of the home gateway is very short, the exchange of accounting packets between the BRAS and the background AAA server is very intensive, and the load of the background AAA server is further increased.
