Description

一种家庭网关及其转发业务的方法 技术领域
本发明涉及通信领域，尤其涉及一种家庭网关及其转发业务的方法。
背景技术
如图1所示，在家庭网关(Residential Gateway，RG)上有多个广域网(Wide Area Network,WAN)口以及局域网(Local Area Network，LAN)口，不同的WAN口通常表示不同的业务，如IPTV(Internet Protocol Television，网络协议电视)、HSI(High Speed Internet，高速网络)、VoIP(Voice over Internet Protocol，网络电话)等，不同的LAN口下可能下挂不同的设备。为了保证这些设备的数据流能够从对应的WAN口出去以使对应的业务正常执行，目前有两种方案，一种是LAN&WAN绑定方案(也称端口绑定)，LAN侧设备只能连接特定的LAN口才能正常的访问WAN侧的服务。另一种是任意端口任意服务(Any Port Any Service，APAS)方案，如图2所示，常见的方式是LAN口下挂设备通过动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)获取IP(Internet Protocol，网络协议)地址，并携带和业务类型相关的DHCP option字段，RG通过识别这些设备的DHCP option字段，给这些设备分配特定段的私网IP，通过区分这些不同段的私网IP，配置源IP策略路由，选择路由WAN口。由于只能选择路由WAN口，导致应用场景受限。
发明内容
本发明实施例提供了一种家庭网关及其转发业务的方法，实现家庭网关LAN侧设备灵活选择路由WAN口或桥接WAN口。

具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
为了解决现有技术家庭网关LAN侧设备通过动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)获取IP地址时，只能选择路由WAN口，应用场景受限。本发明实施例基于图1A或图1B所示的通信系统中提出了一种解决方案，针对DHCP option字段来区分终LAN侧设备需要接入的WAN，实现家庭网关LAN侧设备灵活选择路由WAN口或桥接WAN口。
本实施例中的家庭网关可以是无线路由器网关、数字机顶盒网关，PC家庭网关，数字用户线(DSL)路由器网关，VOIP宽带接入网关，有线多媒体网关。LAN侧设备包括但不局限于：手持设备、车载设备、可穿戴设备、计算设备、终端(terminal)，终端设备(terminal equipment)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、 膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication,MTC)终端等。
如图1所示，本发明公开了一种家庭网关，该家庭网关同时具备LAN口和WAN口，其中WAN口包括两种不同类型的WAN口：路由WAN口和桥接WAN口，路由WAN口的个数和桥接WAN口的个数根据实际需求而定。对于路由WAN口来说，家庭网关具有对应的DHCP服务器，对于桥接WAN口来说，DHCP服务器是独立的，家庭网关不具有对应的DHCP服务器。LAN侧设备通过所述LAN口连接到所述家庭网关，所述家庭网关接收LAN侧设备发送的包括业务请求的DHCP发现报文，所述DHCP发现报文包括DHCP Option字段，所述DHCP Option字段包括一个值，所述值标识所述请求的业务；根据所述值标识的业务与路由WAN口或者桥接WAN口之间的对应关系，选择对应的路由WAN口或者桥接WAN口；通过所述选择的路由WAN口或者桥接WAN口与宽带接入服务器(BRAS，Broadband Remote Access Server)建立链路。
需要说明的是，对于DHCP发现报文而言，每一个DHCP发现报文包括任意多个DHCP Option字段，少则一个，多则不限制，比如DHCP Option 60字段、DHCP Option 77字段、DHCP Option 15字段、DHCP Option 16字段等等。优选的，本发明实施例中指定DHCP Option 60字段，即选择DHCP Option 60字段的值，标识LAN侧设备请求的业务。家庭网关根据所述DHCP Option 60字段的值标识的业务与路由WAN口或者桥接WAN口之间的对应关系，选择对应的路由WAN口或者桥接WAN口，然后家庭网关通过选择的路由WAN口或者桥接WAN口与宽带接入服务器建立链路。LAN侧设备连接到宽带接入服务器进行业务交互。
对于业务类型，可以包括网络电话、视频点播、有线电视、高速上网等等不同的业务类型。
针对图1以及本发明实施例公开的家庭网关，一种场景是，所述值标识的业务对应的是桥接WAN口，则所述家庭网关从所述桥接WAN口转发所述DHCP发现报文(DHCP discover)给所述宽带接入服务器，所述家庭网关接收所述宽带接入服务器返回的DHCP Offer响应报文，记录所述LAN侧设备的源MAC地址和桥接WAN口的绑定关系。家庭网关根据所述LAN侧设备的源MAC地址和 桥接WAN口的绑定关系找到对应的LAN口，将所述DHCP Offer响应报文通过所述LAN口发送给所述LAN侧设备。家庭网关接收所述LAN侧设备发送的DHCP请求报文(DHCP request)，家庭网关根据所述LAN侧设备的源MAC地址和桥接WAN口的绑定关系找到对应的桥接WAN口。进一步的，家庭网关将所述DHCP请求报文通过所述桥接WAN口发送给所述宽带接入服务器；接收所述宽带接入服务器返回的DHCP确认响应报文(DHCP ack)。家庭网关通过所述LAN口将所述DHCP确认响应报文发送给所述LAN侧设备。LAN侧设备检查DHCP服务器(DHCP server)分配的公网IP地址可以使用，所述LAN侧设备根据所述公网IP通过对应的桥接WAN口连接到所述宽带接入服务器。
另一种场景是：DHCP Option字段的值标识的业务对应的是路由WAN口，则所述家庭网关为所述LAN侧设备分配私网IP地址，所述LAN侧设备根据所述IP地址访问所述家庭网关。接着，家庭网关查询本地路由表，根据源IP策略路由选择对应的路由WAN口，所述LAN侧设备通过所述对应的路由WAN口连接到所述宽带接入服务器。
本发明实施例通过DHCP Option字段来区分LAN侧设备是要接入路由WAN口还是桥接WAN口，实现家庭网关LAN侧设备灵活选择路由WAN口或桥接WAN口连接到WAN侧，灵活得进行业务部署。
如图3所示，针对图1所示的家庭网关本发明实施例公开了一种转发业务的方法，包括步骤：
步骤301：家庭网关接收LAN侧设备发送的包括业务请求的DHCP发现报文，所述DHCP发现报文包括DHCP Option字段，所述DHCP Option字段包括一个值，所述值标识所述请求的业务；
步骤302：家庭网关根据所述值标识的业务与路由WAN口或者桥接WAN口之间的对应关系，选择对应的路由WAN口或者桥接WAN口。
以DHCP Option 60字段举例说明，一种方式是DHCP发现报文携带DHCP Option 60字符串“STB”，家庭网关通过查找字符串不同值对应的业务关系数据库，查找得知“STB”代表视频点播业务，家庭网关根据上网业务与路由WAN口或者桥接WAN口之间的对应关系，选择路由WAN口。LAN侧设备通过路由WAN口连接到宽带接入服务器。另一种方式是DHCP发现报文携带DHCP Option 60字符串“VOIP”，家庭网关通过查找符串不同值对应的业务关系数 据库，查找得知“VOIP”代表网络电话业务，家庭网关根据网络电话业务与路由WAN口或者桥接WAN口之间的对应关系，选择桥接WAN口。
步骤303：家庭网关通过所述选择的路由WAN口或者桥接WAN口与宽带接入服务器建立链路。
针对上述步骤302和303，一种场景是，如图4所示，分别以两种LAN侧设备，设备A(Device A)和设备B(Device A)分别访问不同的业务举例说明，如图中所示，对于设备A来说，请求的业务对应路由WAN口，则家庭网关为设备A分配私网IP地址，设备A根据IP地址访问家庭网关。家庭网关查询本地路由表，根据源IP策略路由选择路由WAN口，设备A通过路由WAN口连接到宽带接入服务器。当然，设备A(Device A)和设备B(Device A)也可以是支持不同业务的同一设备。
针对上述步骤302和303，另一种场景是，如图4所示，对于设备B来说，请求的业务对应桥接WAN口，则家庭网关从桥接WAN口转发所述DHCP发现报文给宽带接入服务器，家庭网关接收宽带接入服务器返回的DHCP Offer响应报文，记录设备B的源MAC地址和桥接WAN口的绑定关系。家庭网关根据设备B的源MAC地址和桥接WAN口的绑定关系找到对应的LAN口，将DHCP Offer响应报文通过对应的LAN口发送给LAN侧设备。家庭网关接收LAN侧设备发送的DHCP请求报文，家庭网关根据设备B的源MAC地址和桥接WAN口的绑定关系找到对应的桥接WAN口。进一步的，家庭网关将DHCP请求报文通过WAN口发送给宽带接入服务器，然后接收所述宽带接入服务器返回的DHCP确认响应报文。家庭网关通过LAN口将所述DHCP确认响应报文发送给设备B。设备B检查DHCP服务器分配的公网IP地址是否可以使用，如果可以使用，则设备B根据所述公网IP通过对应的桥接WAN口连接到宽带接入服务器。
本发明实施例通过DHCP Option字段来区分LAN侧设备是要接入路由WAN口还是桥接WAN口，实现家庭网关LAN侧设备灵活选择路由WAN口或桥接WAN口连接到WAN侧，灵活得进行业务部署。
下面结合图4，以图5智能网络机顶盒(Set Top Box，STB)通过家庭网关连接业务举例说明，如图5中所示，智能机顶盒通过LAN2口连接到家庭网关，智能机顶盒(STB)向家庭网关广播DHCP发现报文，一种情况是，DHCP发现报文携带有特定的DHCP Option 60字符串，比如是“STB”，家庭网关通 过查找字符串不同值对应的业务关系数据库，查找得知“STB”代表视频点播业务，家庭网关根据上网业务与路由WAN口或者桥接WAN口之间的对应关系，选择路由WAN口。进一步，家庭网关为设备A分配私网IP地址，设备A根据IP地址访问家庭网关。家庭网关查询本地路由表，根据源IP策略路由选择路由WAN口，设备A通过路由WAN口连接到宽带接入服务器。
还一种情况是，DHCP发现报文携带有特定的DHCP Option 60字符串，比如是“VOIP”，家庭网关通过查找符串不同值对应的业务关系数据库，查找得知“VOIP”代表网络电话业务，家庭网关根据网络电话业务与路由WAN口或者桥接WAN口之间的对应关系，选择桥接WAN口。进一步，家庭网关从桥接WAN口转发所述DHCP发现报文给宽带接入服务器，家庭网关接收宽带接入服务器返回的DHCP Offer响应报文，记录设备B的源MAC地址和桥接WAN口的绑定关系。家庭网关根据设备B的源MAC地址和桥接WAN口的绑定关系找到对应的LAN口，将DHCP Offer响应报文通过对应的LAN口发送给LAN侧设备。家庭网关接收LAN侧设备发送的DHCP请求报文，家庭网关根据设备B的源MAC地址和桥接WAN口的绑定关系找到对应的桥接WAN口。进一步的，家庭网关将DHCP请求报文通过WAN口发送给宽带接入服务器，然后接收所述宽带接入服务器返回的DHCP确认响应报文。家庭网关通过LAN口将所述DHCP确认响应报文发送给设备B。设备B检查DHCP服务器分配的公网IP地址是否可以使用，如果可以使用，则设备B根据所述公网IP通过对应的桥接WAN口连接到宽带接入服务器。
如图6所示，本发明还公开了一种通信装置，包括处理器601、存储器602和总线系统603，所述处理器601和所述存储器602通过该总线系统503相连，所述存储器602用于存储指令，所述处理器用于执行所述存储器602存储的指令，
其中，所述处理器601用于：接收LAN侧设备发送的包括业务请求的DHCP发现报文，所述DHCP发现报文包括DHCP Option字段，所述DHCP Option字段包括一个值，所述值标识所述请求的业务；根据所述值标识的业务与路由WAN口或者桥接WAN口之间的对应关系，选择对应的路由WAN口或者桥接WAN口；通过所述选择的路由WAN口或者桥接WAN口与宽带接入服务器建立链路。
一种场景是，所述值标识的业务对应的是桥接WAN口，则所述家庭网关 从所述桥接WAN口转发所述DHCP发现报文(DHCP discover)给所述宽带接入服务器，所述家庭网关接收所述宽带接入服务器返回的DHCP Offer响应报文，记录所述LAN侧设备的源MAC地址和桥接WAN口的绑定关系。家庭网关根据所述LAN侧设备的源MAC地址和桥接WAN口的绑定关系找到对应的LAN口，将所述DHCP Offer响应报文通过所述LAN口发送给所述LAN侧设备。家庭网关接收所述LAN侧设备发送的DHCP请求报文(DHCP request)，家庭网关根据所述LAN侧设备的源MAC地址和桥接WAN口的绑定关系找到对应的桥接WAN口。进一步的，家庭网关将所述DHCP请求报文通过所述桥接WAN口发送给所述宽带接入服务器；接收所述宽带接入服务器返回的DHCP确认响应报文(DHCP ack)。家庭网关通过所述LAN口将所述DHCP确认响应报文发送给所述LAN侧设备。LAN侧设备检查DHCP服务器(DHCP server)分配的公网IP地址可以使用，所述LAN侧设备根据所述公网IP通过对应的桥接WAN口连接到所述宽带接入服务器。
另一种场景是：DHCP Option字段的值标识的业务对应的是路由WAN口，则所述家庭网关为所述LAN侧设备分配私网IP地址，所述LAN侧设备根据所述IP地址访问所述家庭网关。接着，家庭网关查询本地路由表，根据源IP策略路由选择对应的路由WAN口，所述LAN侧设备通过所述对应的路由WAN口连接到所述宽带接入服务器。
