学习5G知识，势必要去阅读相关的技术标准，而纯英文的标准协议对于初学者来说是个门槛。
个人在学习5G标准3GPP TS 29244-g30过程中，也发现google的机器翻译实在晦涩难懂，所以个人在借助百度翻译（中国人更懂中文）的同时，人工对每句话进行了校对。
在自己学习的同时，也将翻译内容分享给给广大网友。由于个人能力有限，翻译不到位的地方还请各位网友们指正。
5.2.6 Combined SGW/PGW ArchitectureSGW/PGW组合架构
The usage of a combined SGW/PGW remains possible in a deployment with separated control and user planes, see clause4.2.2 of 3GPPTS23.214[2]. This is enabled by supporting a combined Sxa/Sxb interface with a common packet forwarding model, message and parameter structure for non-combined and combined cases.
在控制平面和用户平面分开的部署中，组合SGW/PGW的使用仍然是可能的。这是通过支持组合的Sxa/Sxb接口来实现的，该接口具有通用的包转发模型、消息和参数结构，适用于non-combined和组合情况。
The following additional requirements shall apply to a combined Sxa/Sxb interface between a combined SGW/PGW-C and a combined SGW/PGW-U:
以下附加要求应适用于组合的SGW/PGW-C和组合的SGW/PGW-U之间的组合式Sxa/Sxb接口：
- all the functionalities specified for Sxa and Sxb shall be supported, possibly concurrently, over a combined Sxa/Sxb association;
-为Sxa和Sxb指定的所有功能应通过组合的Sxa/Sxb关联同时支持；
- a single PFCP session may be setup to support both the functionalities of an SGW-U and PGW-U;
-可以设置单个PFCP会话以支持SGW-U和PGW-U的功能；
- the CP function may provision PDRs, QERs, URRs, FARs (possibly with a buffering instruction) and BAR, possibly concurrently, for the same PFCP session;
-CP功能可能同时为同一PFCP会话提供PDR、QER、URR、FAR和BAR；
- the CP function may provision concurrently parameters in a message or for the PFCP session that are applicable to Sxa and Sxb.
-CP功能可在消息中或针对PFCP会话同时提供适用于Sxa和Sxb的参数。
