Address assignment method and address assignment system for intelligent access type decision, and AAA system

Abstract

The invention relates to an address assignment method and an address assignment system for intelligent access type decision, and an AAA system. The method comprises the following steps: a Radius server receives an authentication request message sent by BRAS equipment, wherein the message carries the account name of a user and the IP address of the BRAS equipment connected with the user; the Radius server queries an AAA database according to the account name of the user and the IP address of the BRAS equipment, respectively determines the user IP address assignment type corresponding to the account name of the user as well as the equipment function service scope and the equipment IP address assignment type corresponding to the IP address of the BRAS equipment, determines the IP address assignment type according to the equipment function service scope, the user IP address assignment type and the equipment IP address assignment type, and returns an authentication response message to the BRAS equipment after authentication, wherein the message carries a domain identifier corresponding to the IP address assignment type; and the BRAS equipment calls a corresponding domain template configuration policy according to the domain identifier in the message to assign an IP address for customer premise equipment. Intelligent user IP address access type judgment and address assignment can be realized.

Description

technical field [0001] The present invention relates to communication technology, in particular to an address allocation method and system for intelligent determination of access types, and an authentication, authorization, and accounting (Authentication, Authorization, Accounting, AAA for short) system. Background technique [0002] At present, the IP system runs on the public network, based on the TCP / IP protocol of IPv4, and realizes the UDP Radius Server function of the AAA system. With the continuous development of the Internet, the network is transitioning to the next-generation Internet IPv6 field. During the transition period, there are many combinations of IP address types obtained by broadband users online, and they are no longer the previous Customer Premise Equipment (CPE). A single access type that only assigns IPv4 addresses. [0003] The AAA system is mainly composed of two parts: the Remote authentication dial in user service (Radius for short) program and t...

Problems solved by technology

[0009] With the rapid development of the Internet and the transition period from V4 network to V6 network, the current operation support system can no longer satisfy the precise management and control of users when carrying out broadband services with various IP address access types, and it is also unable to realize the user IP Intelligent determination of address access type
