Method and device for billing Ipv4/Ipv6 dual-stack user

Abstract

An embodiment of the invention provides a method and a device for billing an Ipv4 / Ipv6 dual-stack user, and relates to the field of communication. The method and the device are used for decreasing message interaction between BRAS (broadband remote access server) and an existing background AAA server and reducing impact on the background AAA server. The method for billing the Ipv4 / Ipv6 dual-stack user includes the steps: establishing Ipv4 connection of the Ipv4 / Ipv6 dual-stack user to generate a billing request message; establishing Ipv6 connection of the Ipv4 / Ipv6 dual-stack user to generate a billing update message and realize access connection of the Ipv4 / Ipv6 dual-stack user; expanding existing fields of the billing request message; and summarizing dual-stack information of the billing request message and the billing update message, inserting the summarized dual-stack information into the expanded billing request message to form a new billing request message, and transmitting the new billing request message. The method and the device are used for billing the Ipv4 / Ipv6 dual-stack user.

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 on the access user, authorize and billing. [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 accounti...

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.
