3GPP TS 23501-g51 中英文对照 | 4.1 General concepts

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 23501-g51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。

4.1 General concepts

The 5G System architecture is defined to support data connectivity and services enabling deployments to use techniques such as e.g. Network Function Virtualization and Software Defined Networking. The 5G System architecture shall leverage service-based interactions between Control Plane (CP) Network Functions where identified. Some key principles and concept are to:

5G系统架构定义为支持数据连接和服务，使部署能够使用Network Function Virtualization和Software Defined Networking等技术。5G系统架构应利用Control Plane（CP） Network Functions之间service-based的交互（如已确定）。一些关键原则和概念是：

- Separate the User Plane (UP) functions from the Control Plane (CP) functions, allowing independent scalability, evolution and flexible deployments e.g. centralized location or distributed (remote) location.

-将User Plane（UP）功能与Control Plane（CP）功能分开，允许独立的可扩展性、演进性和灵活的部署，例如集中式位置或分布式（远程）位置。

- Modularize the function design, e.g. to enable flexible and efficient network slicing.

-模块化功能设计，例如，实现灵活高效的网络切片。

- Wherever applicable, define procedures (i.e. the set of interactions between network functions) as services, so that their re-use is possible.

-在适用的情况下，将程序（即网络功能之间的一组交互）定义为服务，以便可以重复使用。

- Enable each Network Function and its Network Function Services to interact with other NF and its Network Function Services directly or indirectly via a Service Communication Proxy if required. The architecture does not preclude the use of another intermediate function to help route Control Plane messages (e.g. like a DRA).

-如果需要，使每个Network Function及其Network Function Services能够通过Service Communication Proxy直接或间接地与其他NF及其Network Function Services交互。该体系结构不排除使用另一种中间功能来帮助路由Control Plane消息（如DRA）。

- Minimize dependencies between the Access Network (AN) and the Core Network (CN). The architecture is defined with a converged core network with a common AN - CN interface which integrates different Access Types e.g. 3GPP access and non-3GPP access.

-最小化Access Network（AN）和Core Network（CN）之间的依赖关系。该体系结构定义为具有通用AN-CN接口的融合核心网络，该接口集成了不同的Access Type，例如3GPP接入和non-3GPP接入。

- Support a unified authentication framework.

-支持统一的验证框架。

- Support "stateless" NFs, where the "compute" resource is decoupled from the "storage" resource.

-支持“无状态”NFs，“计算”资源与“存储”资源分离。

- Support capability exposure.

-支持能力暴露。

- Support concurrent access to local and centralized services. To support low latency services and access to local data networks, UP functions can be deployed close to the Access Network.

-支持对本地和集中服务的并发访问。为了支持低延迟服务和对本地数据网络的访问，可以在Access Network附近部署UP功能。

- Support roaming with both Home routed traffic as well as Local breakout traffic in the visited PLMN.

-支持在拜访PLMN中同时使用Home路由流量和Local分支流量进行漫游。
