用户业务接入方法、 系统和接入 i殳备 本申请要求于 2011 年 3 月 28 日提交中国专利局、 申请号为 201110075547.4、 发明名称为"用户业务接入方法、 系统和接入设备"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
本发明实施例涉及通信技术领域, 尤其涉及一种用户业务接入方法、 系 统和接入设备。 背景技术
随着宽带业务的发展, 家庭宽带用户接入的业务种类越来越多, 如用户 通过一个家庭网关可以接入机顶盒、电脑、 电话,分别对应网络电视( Internet Protocol Television; 筒称: IPTV ) 、 高速上网 ( high speed internet; 筒称: HSI ) 、 网络电话(Voice over Internet Protocol; 筒称: VOIP )业务。
在现有应用场景中, 需要进行一定配置才能使业务到达正确的网关或服 务器, 如: 为每种业务建立不同的用户虚拟局域网 ( Customer Virtual Local Area Network; 筒称: CVLAN ) , 在接入设备上根据 CVLAN识别业务类型, 并将标识的业务类型桥接到指定的业务虚拟局域网 (Service Virtual Local Area Network; 筒称: SVLAN )上。 当运营商给某个用户家庭开通业务时, 需要在其家庭网关上预先配置每种业务上行时所使用的 CVLAN标识, 并且将 该 CVLAN标识和接入设备上与该用户关联的端口上配置的 CVLAN保持一致; 在接入设备上根据该用户端口和 CVLAN识另 出一条业务流后, 将该业务流桥 接到指定的 SVLAN上。
现有技术在接入设备上需要预先配置 CVLAN到 SVLAN的桥接对应关系, 配置完成后即为固定的映射关系。 例如: 为某个用户家庭开通业务时, 首先, 在接入设备上配置三种业务类型的 SVLAN, 分别为 HIS对应" SVLAN 100"、 IPTV对应" SVLAN 101"、 VOIP对应" SVLAN 102"; 在用户端口— 1上配置这三 种 SVLAN对应的 CVLAN分别为 "CVLAN10"、 "CVLAN 1 1", "CVLAN 12"; 然 后, 将该用户端口的三种业务分别桥接(bridge to )到对应的 SVLAN上, 如: "PORT1 CVLAN 10 bridge to SVLAN 100"、 "PORT1 CVLAN 1 1 bridge to SVLAN101 "、 "PORT1 CVLAN 12 bridge to SVLAN 102"。 最后, 在该用户的 家庭网关的各个端口(FE1、 FE2、 FE3 )上进行业务配置: "FE1 add CVLAN 10"、 "FE2 add CVLAN 1 1"、 "FE3 add CVLAN 12", 其中, 正确配置的情况 下端口 FE1连接 HSI业务, 端口 FE2连接 IPTV业务, 端口 FE3连接 VOIP业务。
但是, 如果运营商在开通业务时, 将家庭网关上的业务配置错误, 会导 致业务不通, 例如: 在家庭网关上将端口 FE1的报文 CVLAN标识配置为 "CVLAN 15", 但接入设备上预先配置对应关系中没有" CVLAN15", 将导致连 接端口 FE1的 HSI业务不通。 另外,如果用户将网线插错,也会导致业务不通, 例如:用户将 HSI业务的网线插入端口 FE2,将 IPTV业务的网线插入端口 FE1 , 使得 HSI业务的报文携带" CVLAN1 1"、 IPTV业务的报文携带" CVLAN 10", 根 据接入设备上预先配置的对应关系, HSI业务桥接到" SVLAN101", IPTV业务 桥接到 "SVLAN 100", 将导致 HSI和 IPTV业务都不通。
现有技术, 需要在接入设备预先配置 CVLAN和 SVLAN的关系, 并且接入 设备上配置的 CVLAN需要与家庭网关上的 CVLAN—致, 配置方法复杂, 容易 出错, 从而导致业务不通。 发明内容

为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
图 1为本发明实施例中多业务接入场景的示意图, 如图 1所示, 一个用户 可以设置一个家庭网关 20, 其中, 在 HSI业务中, 个人电脑 ( PC ) 可以通过 该家庭网关 20访问互联网(internet ) ;在 IPTV业务中,机顶盒(Set Top Box; 筒称: STB )可以通过该家庭网关 20接收电视节目; 在 VOIP业务中, IP话机 ( IP PHONE )可以通过该家庭网关连接到软交换。 在多业务接入场景下, 接 入设备 30作为汇聚设备和桥接设备,可以将用户家庭网关 20上的业务汇聚后, 传入上层网络。 其中, 在家庭网关向接入设备发送的报文中被添加的虚拟局 域网标识(VLANID ) 为 CVLAN标识, 当报文到达接入设备后, 接入设备向 报文中添加 VLAN I D为 S VLAN标识。
针对上述图 1的结构图,对用户业务的接入方法进一步的描述如图 2所示。 图 2为本发明实施例一提供的用户业务接入方法的流程图, 如图 2所示, 该用 户业务接入方法包括:
步骤 201、接收家庭网关发送的第一报文, 所述第一报文携带与所述第一 4艮文匹配的用户虚拟局域网标识;
在步骤 201之前,可以将接入设备上各个用户端口的业务接入方式预先配 置为自动感知方式。 设置为自动感知方式的用户端口, 在接收到家庭网关发 送的报文后, 将对接收到的报文启动自动感知过程: 如果设置为自动感知方 式的用户端口收到第一报文(例如: 某一业务类型的首个报文后接入错误后 的第一个报文, 该用户端口上没有该第一报文携带的用户虚拟局域网标识对 应的映射关系) , 可以建立该第一 4艮文的用户虚拟局域网标识到业务虚拟局 域网标识的映射关系; 如果不是第一报文, 则可以直接根据该报文的用户虚 拟局域网标识查找对应的业务虚拟局域网标识后转发。
步骤 202、 根据所述第一报文的特征信息, 获取与所述第一报文匹配的业 务虚拟局域网标识;
其中, 可以预先在接入设备上配置业务类型与业务虚拟局域网标识的对 应关系, 例如: 在接入设备上通过一个对应关系表存储将业务类型与业务虚 拟局域网标识的对应关系。 进一步地, 步骤 202具体可以包括: 根据所述第一 报文的特征信息, 分析得到所述第一报文的业务类型; 根据所述业务类型, 获取所述业务类型匹配的业务虚拟局域网标识。 其中, 特征信息优选可以为 用户封装类型、 拨号报文关键字、 报文格式、 版本号或以太网类型的至少一 种, 所述业务类型优选可以包括高速上网业务、 网络电视业务、 网络电话业 务、 互联网协议第 4版(IPv4 ) 业务和互联网协议第 6版(IPv6 ) 业务的至少 一种。
步骤 203、 根据所述用户虚拟局域网标识和所述业务虚拟局域网标识, 建 立所述用户虚拟局域网标识和所述业务虚拟局域网标识的映射关系;
步骤 204、根据所述用户虚拟局域网标识和所述业务虚拟局域网标识的映 射关系; 将所述第一报文发送到所述业务虚拟局域网标识对应的网络。
其中, 接入设备上用户端口的转发芯片根据映射关系转发第一报文的方 法具体可以为: 接收第一报文的用户端口可以根据该第一报文的用户虚拟局 域网标识对应的映射关系, 在该第一报文中添加该第一报文匹配的业务虚拟 局域网标识, 然后转发该第一报文; 或者, 接收第一报文的用户端口根据该 第一报文的用户虚拟局域网标识对应的映射关系, 将该第一报文中的用户虚 拟局域网标识替换为与第一报文匹配的业务虚拟局域网标识, 然后转发所述 第一报文。
其中, 由于分析报文的特征信息, 获取报文的业务类型过程相对复杂, 可以由该接入设备的 CPU执行。 具体地, 接入设备的某一用户端口接收到第 一报文(一般可以为该用户端口收到的某一业务类型的首个报文)后, 可以 由该接入设备的 CPU对第一报文进行分析, 根据第一报文的特征信息获取匹 配的业务虚拟局域网标识后, 建立第一报文的用户虚拟局域网标识和业务虚 拟局域网标识的映射关系; 然后, CPU可以指示该用户端口的转发芯片根据 建立后的用户虚拟局域网标识和业务虚拟局域网标识的映射关系, 转发该用 户端口后续收到的第二报文(与第一报文携带的用户虚拟局域网标识相同的 报文) 。 因此, 步骤 202和步骤 203可以由接入设备的 CPU执行, 步骤 204则 可以由接入设备该用户端口上的转发芯片执行。
此外, 还可以对接入设备上各个用户端口对应的用户虚拟局域网标识和 业务虚拟局域网标识的映射关系进行检查, 对不必要的映射关系进行老化, 具体可以为以下示例:
示例一、 在设定时间内未接收到携带所述用户虚拟局域网标识的报文, 则将所述用户虚拟局域网标识和所述业务虚拟局域网标识的映射关系老化; 或
示例二、 接收到家庭网关发送的端口掉线通知, 则将所述用户虚拟局域 网标识和所述业务虚拟局域网标识的映射关系老化。
本实施例接入设备接收第一报文的用户端口, 根据第一报文的特征信息 获取该报文匹配的业务虚拟局域网标识后, 可以根据该第一报文携带的用户 虚拟局域网标识, 自动建立该用户虚拟局域网标识和该业务虚拟局域网标识 的映射关系, 不需要在接入设备上预先配置用户虚拟局域网标识与业务虚拟 局域网标识的映射关系, 筒化了用户业务开通时的接入配置; 并且用户随意 插接家庭网关上的网口, 都能够得到正确的用户虚拟局域网标识与业务虚拟 局域网标识的映射关系, 从而避免由于用户插错家庭网关上的网口造成的业 务不通, 因此该用户业务接入方法的配置筒单、 不易出错, 可以保证业务畅 通。
图 3为本发明实施例二提供的用户业务接入方法的流程图, 如图 3所示, 该用户业务接入方法包括:
步骤 301、 在接入设备上配置某用户端口的业务接入方式为自动感知 ( auto-sensing ) 方式。 其中, 设置为自动感知方式的用户端口, 在接收到家庭网关发送的报文 后, 将启动自动感知过程, 如果该用户端口上的 CVLAN标识与 SVLAN标识映 射关系中存在该报文携带的 CVLAN标识, 可以根据该 CVLAN标识与 SVLAN 标识的映射关系, 直接转发该报文; 否则, 可以根据该报文的特征信息例如: 某种封装或者拨号关键字查找到其业务类型对应的 SVLAN标识, 并建立该报 文携带的 CVLAN标识该 SVLAN标识的映射关系。
步骤 302、 家庭网关将从不同以太网(ETH )口的报文打上不同的 CVLAN 标识。
步骤 303、接入设备从该用户端口接收到家庭网关发送的报文后, 判断该 报文中携带的 CVLAN标识是否已经存于该用户端口 (其中, 接入设备中可以 保存一个映射关系表, 在映射关系表记录该接入设备的每一个用户端口包括 的 CVLAN标识与 SVLAN标识的映射关系。接入设备可以判断映射关系表保存 的该用户端口包括的映射关系中, 是否存在该报文携带的 CVLAN标识, 如果 存在, 说明该报文中携带的 CVLAN标识已经存于该用户端口中) , 如果是, 则可以根据该 CVLAN标识与 SVLAN标识的映射关系直接转发该报文(即将该 报文中 CVLAN的桥接到对应的 SVLAN上) ; 如果不是, 则执行步骤 304。
接入设备上该用户端口的转发芯片根据该 CVLAN标识与 SVLAN标识的 映射关系直接转发该报文的具体方法可以为: 向携带 CVLAN标识的报文中添 加对应的 SVLAN标识, 或将该报文中的 CVLAN标识替换成对应的 SVLAN标 指定的宽带远程接入服务( Broadband Remote Access Server;筒称: BRAS ) 或服务器。
步骤 304、接入设备将该报文作为该用户端口接收的第一报文(某一种业 务类型的首个报文或出错后的第一个报文)进行处理, 将该第一报文送到接 入设备的 CPU进行分析, 为了保证 CPU不受沖击, 可以将该第一报文送 CPU 使能, 在 CPU对该第一报文分析时其他需要送入 CPU的报文将被丢弃, CPU 对该第一报文分析结束后再去使能。 CPU先匹配得到该第一报文的用户封装 类型或者拨号报文关键字等对应的 SVLAN标识, 然后提取该第一报文的 CVLAN标识, 建立该 CVLAN标识到该 SVLAN标识的映射关系, 从而建立该 第一报文的 CVLAN到对应的 SVLAN的桥接关系;后续该用户端口收到的具有 同样 CVLAN标识的第二报文可以桥接到对应的 S VLAN。
步骤 305、 当家庭网关的端口掉线 (shutdown ) 或者该长时间未收到具 有该 CVLAN标识的报文时, 可以将该 CVLAN标识对应的映射关系老化。
具体地, 接入设备将某一用户端口的业务接入方式预先配置为自动感知 ( auto-sensing )方式的连接, 家庭网关向接入设备上行的报文携带有家庭网 关上某端口配置的 CVLAN标识;接入设备捕获具有新 CVLAN标识的第一报文 或具有已存在 CVLAN标识的第二报文后,在接入设备上可以将 CVLAN标识映 射到对应的 SVLAN标识。
图 4为本发明实施例二提供的用户业务接入方法的应用于不同业务类型 的示意图, 如图 4所示, 例如: 在家庭网关上配置三种业务, 第一种业务为高 速上网 (HSI ) 业务, 采用以太网承载点对点协议(PPPOE )拨号; 第二种 业务为网络电视( IPTV )业务; 第三种业务为网络电话(VOIP )业务, 采用 IP话机, 通过动态主机设置协议 ( Dynamic Host Configuration Protocol; 筒 称: DHCP ) 的方式获取 IP, 用户封装类型为 IP〇E。 在家庭网关的三种业务 HSK IPTV、 VOIP对应的三个 ETH口的 CVLAN标识分别为" CVLAN1"、 "CVLAN2"、 "CVLAN3"。 接入设备在用户端口上分别配置三种自动感知方式 (自动感知— 1、 自动感知— 2、 自动感知— 3 ) ,其 SVLAN标识分别为" SVLAN1"、 "SVLAN2", "SVLAN3"„ 其中, SVLAN的业务匹配方式为: SVLAN1匹配用 户封装类型为 PPP0E报文, SVLAN2匹配的用户封装类型为 IGMP报文, SVLAN3匹配的用户封装类型为非 IGMP的 I P0E报文;
当 HSI业务的用户采用 PPP0E拨号时, 家庭网关发出的 PPP0E报文带有 CVLAN 1 , 在接入设备在某一用户端口上捕获该 PPPOE报文后, 假设为第一 个 PPPOE4艮文, 可以匹配到用户封装类型为 PPPOE , 则建立 CVLAN1到 SVLAN1的映射关系, 并将 CVLAN1配置到该用户端口;
当 IPTV业务的用户通过机顶盒(STP )进行点播时, 通过互联网组管理 协议( Internet Group Management Protocol; 筒称: IGMP )发送 IGMP报文 到接入设备, 该 IGMP报文带有 CVLAN2, 接入设备识别出某一用户端口上送 的 IGMP报文后, 可以匹配到用户封装类型为 IGMP , 在该用户端口上配置 CVLAN2到 SVLAN2的映射关系, 并将 CVLAN2配置到该用户端口;
当 VOIP业务用户的 IP话机通过 DHCP获取 IP时, DHCP 请求报文携带 CVLAN3, 在接入设备上捕获该 DHCP 请求报文, 如果匹配到用户封装类型 为 IPOE, 则建立 CVLAN3到 SVLAN3的映射关系, 并将 CVLAN3配置到该用 户端口;
此外, 如果接入设备监控到该用户端口保存的某个 CVLAN标识在一段时 间内没有报文上行, 可以将该 CVLAN标识对应的映射关系老化。 或者家庭网 关上某个端口掉线 (shutdown ) 时, 可以向接入设备发送端口掉线通知, 在 端口掉线通知中携带掉线的端口对应的 CVLAN标识, 接入设备可以将该掉线 的端口对应的 CVLAN标识的映射关系老化。
图 5为本发明实施例二提供的用户业务接入方法的应用于 IP报文的示意 图, 如图 5所示, 用户通过家庭网关上网时, 其报文可能为 IPv4报文, 也可能 为 IPv6报文; IPv4报文、 IPv6报文都属于 IP报文, ^报文可以封装在???报文 中, 然后再封装到以太包中, 上述的 PPP0E报文就是这种封装形式; IP报文 也可以直接封装到以太包中, 上述的 IP0E报文就是这种封装形式; 实际应用 时, 运营商期望将 IPv4报文和 IPv6报文传送到不同的传输网, 因此, 本实施 例在接入设备上可以根据 IP报文的版本号 ( version ) 或者以太网类型 ( ETHTYPE )的识另 可以区分该 IP报文是 IPv4报文还是 IPv6报文, 将 IPv4 报文、 IPv6报文分别桥接到不同的 SVLAN上。
本实施例在接入设备上并没有预先配置用户的 CVLAN标识与 SVLAN标 识的映射关系, 而是通过对第一个报文(接收该第一报文的用户端口上不存 在该第一报文的 CVLAN标识与 SVLAN标识)捕获后分析得出的, 是一种自动 感知(auto-sensing )的过程, 筒化了配置过程; 此外, 用户随意插接家庭网 关上的网口, 都能够得到正确的用户虚拟局域网标识与业务虚拟局域网标识 的映射关系, 可以避免由于用户插错家庭网关上的网口造成的业务不通; 由 接入设备上捕获业务的第一个报文后, 可以根据该报文的特征 ixnxi分析得到 匹配的 SVLAN标识, 从而将该报文桥接到正确的 SVLAN上, 因此该用户业务 接入方法的配置筒单、 不易出错, 可以保证业务畅通。
