Description

业务流转发功能部署方法、装置及系统 技术领域
本发明涉及通信技术领域，特别涉及一种业务流转发功能部署方法、装置及系统。
背景技术
在演进分组系统(英文：Evolved Packet System；简称：EPS)中，服务网关(英文：Serving Gateway；简称：S-GW)、分组数据网络网关(英文：Packet Data Network Gateway；简称：P-GW)作为转发面网元，既具有转发功能，也具有逻辑控制功能，转发面网元的负荷较大，因此，出现了一套开放流(英文：OpenFlow)协议，OpenFlow协议将传统的物理固定的硬件改造成为动态可编程的软件可定义网络(英文：Software Defined Network；简称：SDN)，实现了网关的控制面网元与转发面网元的分离。控制面网元通过OpenFlow协议对转发面网元进行控制，使转发面网元对业务流进行转发。每个业务流包括多个不同的报文。
现有技术中，将SDN思想引入到EPS的核心网即演进的分组核心网(英文：Evolved Packet Core；简称：EPC)，得到网关的控制面网元GW-C和转发面网元GW-U分离的网络结构，如图1所示，控制面网元GW-C01与其他控制面网元如移动性管理实体(英文：Mobility Management Entity；简称：MME)02、策略和计费规则功能(英文：Policy and Charging Rules Function；简称：PCRF)设备03、归属用户服务器(英文：Home Subscriber Server；简称：HSS)04等集中部署，其中，控制面网元GW-C01用于决策用户设备(英文：User Equipment；简称：UE)的业务流的报文的处理规则，并通过控制面网元GW-C01与转发面网元GW-U05之间的接口(该接口可以采用OpenFlow协议)将该处理规则发送给转发面网元GW-U05，转发面网元GW-U05再根据该处理规则实现对UE的业务流的报文的处理，再将处理后的业务流的报文发送至外部数据网络06。图1中，基站07先将UE的业务流的报文发送至回程网络即Backhaul网络08，回程网络08 再将该报文发送至转发面网元GW-U05。由于回程网络08是基于IP地址对业务流的报文进行转发的，所以，为了使UE的业务流的报文顺利路由到相应的转发面网元上，转发面网元的IP地址被绑定在相应的转发面网元上。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
在实际部署场景如数据中心云平台或网络功能虚拟化(英文：Network Function Virtualization；简称：NFV)平台中，转发功能是以虚拟网络功能(英文：Virtualized Network Function；简称：VNF)的形式进行部署的，由于VNF具有动态扩缩容的特点，业务流可能需要频繁的在不同的VNF间进行迁移，但由于转发面网元的IP地址被绑定在相应的转发面网元，业务流在迁移的过程中需要对IP地址进行绑定和解绑，所以业务流无法频繁的在不同的VNF间进行顺利的迁移，因此，业务流转发的灵活度较低。

图5-1是本发明实施例提供的一种业务流转发功能部署方法的流程图，该方法可以用于图2所示的实施环境中，也可以用于图5-2所示的实施环境中，在图5-2中，控制面网元001作为移动网关控制器，对至少一个转发面网元004、BS005进行控制；基础设施控制器002作为基础设施层的控制器，对基础设施转发器003进行控制。基础设施转发器003用于转发BS005和转发面网元004之间的报文。007为UE，006为PDN网络。至少一个转发面网元包括第一转发面网元0041和第二转发面网元0042。
如图5-1所示，该方法可以包括：

需要说明的是，第一业务流转发标识可以由控制面网元确定，也可以由第一目标转发面网元确定。当第一业务流转发标识由第一目标转发面网元确定时，该过程可以为：控制面网元先确定为UE服务的第一目标转发面网元对应的第一目标转发面网元标识，再向第一目标转发面网元标识指示的第一目标转发面网元发送转发标识确定消息，第一目标转发面网元接收到该转发标识确定消息后确定第一业务流转发标识，示例的，该第一业务流转发标识可以为UE的IP地址。

步骤509、BS向控制面网元发送建立应答消息。
步骤508中的建立请求消息包括第一业务流转发标识(IP1，TEID1)，所以BS需要向控制面网元发送建立应答消息，建立应答消息包括BS的指示信息，BS的指示信息可以为BS的IP地址和下行TEID。

至此，UE与PDN网络的连接已建立完毕，当用户业务流的报文需要转发 时，如图5-2所示，上行报文由UE007发送至BS005，BS005在该上行报文中添加第一业务流转发标识，后续可以根据第一业务流转发标识对相应的转发规则和业务处理策略进行匹配。BS005根据层2(传输层)或层3(应用层)的路由协议将该上行报文发送至基础设施转发器003，基础设施转发器003根据上行报文的转发规则，将该上行报文转发至目标转发面网元，目标转发面网元再按照第一业务处理策略对该上行报文进行相应的业务处理，并将处理后的上行报文发送至PDN网络006或通信对端；下行报文由PDN网络006或通信对端发送至目标转发面网元，目标转发面网元再按照第二业务处理策略对该下行报文进行相应的业务处理，并将处理后的下行报文发送至基础设施转发器003，基础设施转发器003根据下行报文的转发规则，将处理后的下行报文转发至BS005，BS005再将处理后的下行报文发送至UE007。
