3GPP TS 23501-h20 中英文对照 | 4.4.6 5G LAN-type Services

Posted 2021-12-29 COCOgsta

个人在学习5G标准3GPP TS 23501-h20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。

4.4.6 5G LAN-type Services

4.4.6.1 User plane architecture to support 5G LAN-type service

The general User Plane architectures described in clause 4.2.3 and clause 4.2.4 apply to 5G LAN-type services, with the additional options described in this clause.

第4.2.3条和第4.2.4条中描述的通用User Plane架构适用于5G LAN-type服务，本条中描述了其他选项。

Figure 4.4.6.1-1 depicts the non-roaming user plane architecture to support 5G LAN-type service using local switch.

4.4.6.2 Reference points to support 5G LAN-type service

N19: Reference point between two UPFs for direct routing of traffic between different PDU Sessions without using N6. It has a per 5G VN group granularity.

N19：两个UPF之间的参考点，用于在不使用N6的情况下在不同PDU Session之间直接路由流量。它具有每5G VN组粒度。
