IP终端接入网络的方法和装置 本申请要求于 2010年 12月 31 日提交中国专利局、 申请号为 201010617543. X、 发 明名称为 " IP终端接入网络的方法和装置"的中国专利申请的优先权, 其全部内容通过 引用结合在本申请中。 技术领域 本发明涉及网络领域, 尤其涉及一种 IP终端接入网络的方法和装置。 背景技术 目前, 宽带用户使用 IP终端 (IP Terminal) 通过接入网络 (access network) 连接 到 BRAS (Broadband Remote Access Server 宽带接入服务器)。 BRAS为 IP终端配置 IP 地址及其他 IP 网络参数, 实现 IP 终端接入 IP 网络的功能。 AAA (Authentication, Authorization, and Accounting)服务器部署在 IP网络中, 用于实现 IP终端接入网络的认 证、授权、计费功能。 BRAS与 AAA服务器通过 RADIUS ( Remote Authentication Dial In User Service, 远程用户拨号认证系统) 协议或者 DIAMETER协议通信。 具体网络结构 如图 1所示。
IP终端是具有 IP通信能力设备的总称, 具体可以是 PC (Personal Computer, 个人 计算机), 也可以是家庭网关 CPE (customer premises equipment, 用户边缘设备), 或者 其他支持 IP协议桟的终端。
IP终端内部实现 IP协议桟。 IP终端实现的 IP协议可以是 IPv4协议(Internet Protocol Version 4), 也可以是 IPv6 (Internet Protocol Version 6) 协议, 或者是同时支持 IPv4和 IPv6协议。 IP终端接入 BRAS的链路层协议可以是 PPPOE (PPP over Ethernet), 称为 PPPOE接入方式; 或者是 Ethernet接入, 称为 IPOE接入方式。 不同的接入方式, 不同 的 IP协议版本, BRAS为 IP终端配置 IP地址的协议方式也不同。
现有技术方案中, 区分支持不同 IP协议类型 IP终端的方法是为不同 IP协议类型 IP终端划分不同的域(domain), 用户 IP终端认证的用户名中携带 domain信息。 例如, IPv4 终端的用户名命名规则为 usemame@ipv4domain; IPv6 终端的用户命名规则为 username@ipv6domain; 同时支持 IPv4 与 IPv6 类型终端的用户命名规则为 usemame@dualstackdomain。 BRAS根据用户域(domain)信息决定 IP终端的 IP协议类 型, 例如 BRAS判断如果认证用户名域为 ipv4domain, 说明 IP终端支持 IPv4协议, 需 要为该 IP终端配置 IPv4地址;如果认证用户名域为 ipv6domain,说明 IP终端支持 IPv6 协议, 需要为该 IP终端配置 IPv6地址, 如果 IP终端是 CPE, 还需要通过 DHCP-PD方 式配置委派的 IPv6地址前缀。
然而, 现有实现方式, 如果用户更改或者增加 IP终端支持的 IP协议类型, 需要更 改用户名中的域类型, BRAS才能为 IP终端配置正确 IP协议版本的 IP地址, 操作方式 不灵活, 不易于网络维护。 发明内容
本发明实施例提供一种 IP终端接入网络的方法和装置, 以解决现有技术中用户更 改或者增加 IP终端支持的 IP协议类型时, 需要更改用户名中的域类型, BRAS才能为 IP终端配置正确的 IP协议版本的 IP地址的问题。
