3GPP TS 29244

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。

5.13.2 Address Resolution Protocol or IPv6 Neighbour Solicitation Response by SMF SMF的地址解析协议或IPv6邻居请求响应

If the SMF requests the UPF to forward all Address Resolution Protocol (ARP) (see IETF RFC 826 [32]) or IPv6 Neighbour Solicitation (see IETF RFC 4861 [33]) traffic to the SMF to respond to the ARP or IPv6 Neighbour Solicitation based on the local cache information for Ethernet PDU sessions, the SMF shall provision a PDR in the UPF with:

如果SMF请求UPF将所有Address Resolution Protocol或IPv6 Neighbour Solicitation流量转发给SMF，以基于Ethernet PDU会话的本地缓存信息响应ARP或IPv6 Neighbour Solicitatio求，则SMF应在UPF中提供PDR，包括：

- an Ethernet Packet Filter containing EtherType 2054 (hexadecimal 0x0806) and associate the PDR with a FAR, for forwarding ARP traffic to the SMF; and/or

-Ethernet Packet Filter，包含EtherType 2054，并将PDR与FAR相关联，用于将ARP流量转发到SMF；和/或

- a PDI containing an application ID such that the identified application ID matches against EtherType 34525 (hexadecimal 0x86DD), IPv6 Next Header type as 58 and ICMP Field Type as 135 and associate the PDR with a FAR, for forwarding IPv6 Neighbour Solicitation traffic to the SMF.

-包含应用ID的PDI，使得所识别的应用ID与EtherType 34525、IPv6 Next Header类型58和ICMP Field Type 135匹配，并将PDR与FAR相关联，用于将IPv6 Neighbour Solicitation流量转发到SMF。

In this case, the user plane packets shall be forwarded between the CP and UP functions by encapsulating the user plane packets using GTP-U encapsulation (see clause 5.3.1).

在这种情况下，应通过使用GTP-U封装来封装用户平面分组，在CP和UP功能之间转发用户平面分组。

The SMF shall respond to ARP and/or IPv6 Neighbour Solicitation as specified in 3GPP TS 23.501 [28], clause 5.6.10.2 in this case.

在这种情况下，SMF应响应3GPP TS 23.501[28]第5.6.10.2条中规定的ARP和/或IPv6 Neighbour Solicitation。
