S310, 用户开始访问互联网, 这时用户的浏览器终端发出 Http 4艮文。
S312 , 家庭网关设备收到该报文后, 由于无法判定发送该报文的用户类 型, 所以首先把报文丢弃, 并返回 Http重定向报文, 将用户的浏览器重定向 到网关设备的用户权限配置页面上。
S314, 用户在用户权限配置页面提示的指导下, 输入用户名和密码, 然 后网关设备的用户管理模块对该信息进行鉴权操作。 S316, 鉴权成功后, 用户管理模块通过报文获得用户终端的 IP或 MAC 地址等信息, 并和用户名绑定, 并把该 IP或 MAC信息内容一起通知绿色上 网管理模块, 绿色上网管理模块根据该 IP/MAC信息和用户的绑定关系, 把 该用户的策略建立在对应的 IP和 MAC地址上; 同时, 网关策略路由模块就 该 IP/MAC地址信息生成策略路由规则。
S318, 用户再次上网, 该报文进入网关设备的网络层时, 首先是进入路 由处理部分进行选路操作, 由于有了步骤 S216 中配置的策略路由信息, 所 以该报文自动选择所需要的 Wan接口 (普通接口或绿色上网接口)。 选路结 束后, 报文进入绿色上网控制的过滤部分, 由于网关设备的网络层根据该用 户的 IP/MAC建立了新的规则, 所以网关的网络层不再强制返回 Http重定向 文, 而是让用户的 Http ·ί艮文在网络层顺利通过, 最后该 4艮文进入对应的 Wan连接模块发送出去。
S320,报文通过局方接入设备,业务服务提供方在此处获取用户的报文, 并取出该报文的访问内容, 并和该报文的源地址、 拨号帐号等信息绑定在一 起, 发送到业务服务提供方的策略服务器。
S322, 策略服务器根据该用户信息以及报文内容, 判断该报文是否在该 用户的访问权限之内, 如果访问没有越权, 则不处理; 否则立即执行步骤 S324。
S324 , 判断该用户访问越权后, 业务服务提供方在接入设备侧向网关发 送 TCP中止连接的欺骗报文, 当用户浏览器收到后, 误认为连接已经中断, 则不再进行正常工作, 从而实现整个网络访问控制流程。 参考图 4、 图 5, 说明用于实现图 3所示的网络访问控制方法的网络访 问控制系统。 如图 4所示, 该网络访问控制系统主要包括绿色上网门户网站 402、 策略服务器 404、 内容服务器 406、 网管设备 408、 接入设备 410、 以 及家庭网关设备 412、 互联网服务器 414等。 其中: 绿色上网门户网站 402由业务服务提供方提供,供用户设定网络过滤策 略。 内容月良务器 406提供互联网上 URL地址的分级信息, 以供策略服务器 查询, 判断报文类型。 网管设备 408是局方的业务管理、 受理设备的总称, 具体包含很多部分 (如前台设备、 97系统、访问控制服务器( Access Control Server, 简称 ACS ) 等)。 网管设备为用户开通业务, 并把用户信息发送到业务服务提供方以及家 庭网关设备上。 接入设备 410也是局方(业务方)在接入端的设备总称, 包含数字用户 线接入月良务器(DSL Acess Multiplexer, Dslam )、 宽带接入艮务器( Broadband Remote Access Server, 简称 BRAS )、 交换机、 镜像交换机等。 该部分的主要 功能包括: 建立用户的拨号连接; 镜像用户传输的报文; 提取报文中的关键 信息 (如报文访问 URL地址、 报文 IP、 对应用户信息等); 同后方的策略服 务器通讯, 分析判断用户是否有权访问; 以及发送伪造的禁止访问报文等工 作。 家庭网关设备 412是绿色上网业务中多种用户功能的主要实现者,该网 关实现用户鉴权、 用户选路、 用户访问内容过滤等工作。 其中, 如图 5所示, 用于实现用户权限鉴定、 4艮文动态路由等功能的网 关设备 412包括用户管理模块 4122、策略路由模块 4124、绿色上网模块 4126、 拨号( Wan )连接模块 4128等。 网关设备实现用户权限鉴定、 报文动态路由 等功能的流程为: 用户到局方申请绿色上网业务, 业务开通后, 局方网管设 备自动把业务参数信息推送到用户的网关设备上; 网关设备的 Wan连接模块 根据绿色上网的参数信息, 在已建立的普通 Wan连接的基础上, 再建立绿色 上网拨号连接; 用户管理模块根据该信息中的用户信息, 建立绿色上网用户, 如家长, 小孩等; 绿色上网管理模块在网关网络层配置缺省不可访问互联网 的规则, 同时, 配置家长和小孩的过滤策略; 用户开始访问互联网, Http报 文到达网关设备, 立即被网关设备的缺省策略丢弃, 并将用户重定向到网络 权限配置页面上, 用户在页面提示的指导下, 输入用户名和密码; 用户管理 模块进行鉴权操作,鉴权成功后,用户管理模通过报文获取用户的 IP或 MAC 信息, 并通知策略路由模块, 就该 IP/MAC建立策略路由规则; 同时通知绿 色上网管理模块, 将该用户的策略生效。 当用户完成认证页面的工作, 再次访问互联网时, Http报文到达网关设 备的协议^ «, 首先通过策略路由处理部分选择对应的普通连接或绿色上网连 接, 然后经过网络层过滤部分, 进入新的处理策略, 不再被丢弃, 而是直接 通过, 最后通过普通 Wan连接或者绿色上网 Wan连接发送出去, 从而完成 对用户权限的鉴权管理流程。 通过以上流程, 实现了用户鉴权功能, 并解决了多种用户同时上网的管 理问题。 本发明利用局方、 业务服务提供方、 以及用户的网关设备的共同作用, 实现了网络访问控制功能。 在这个业务中, 局方负责用户业务权限受理, 业 务服务提供方提供网络访问过滤服务, 用户网关设备实现用户管理, 从而解 决了多用户同时上网的问题。 本领于技术人员将很容易了解到本发明其它优点和修改。 因此, 本发明 更广泛的方面并不限于本文中示出以及描述的特定细节和典型实施例。因此, 可在不脱离由权利要求及其等效物所限定的本发明的精神或范围的条件下做 出各种修改。
