个人在学习5G标准3GPP TS 29244-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。
5.13.5 Reporting of UE MAC addresses to the SMF
In a PFCP Session Establishment Request or a PFCP Session Modification Request, the SMF may request the UPF to start or stop (in a PFCP Sesssion Modification Request only) reporting the UE MAC addresses, i.e. the different MAC (Ethernet) addresses used as source address of frames sent UL by the UE in a PDU Session, by:
在PFCP Session Establishment Request或PFCP Session Modification Request中，SMF可以通过以下方式请求UPF开始或停止（仅在PFCP Session Modification Request中）报告UE MAC地址，即，不同的MAC（Ethernet）地址作为UE在PDU会话中UL发送的帧的源地址：
- creating a URR requesting the UPF to report Ethernet traffic information (i.e. with the Reporting Trigger set to 'MAC Addresses Reporting'); and
-创建URR，请求UPF报告Ethernet流量信息（即，Reporting Trigger设置为“MAC Addresses Reporting”）；和
- associating the URR to the PDR provisioned for the UL traffic of the PDU session.
-将URR与为PDU会话的UL流量提供的PDR相关联。
The SMF may additionally request the UPF to detect and report when no user plane packets are received for an UE MAC address, by provisioning the Ethernet Inactivity Timer IE in the URR.
SMF还可以通过在URR中设置Ethernet Inactivity Timer IE，请求UPF检测并报告何时没有接收到针对UE MAC地址的用户平面分组。
When being requested to start reporting the UE MAC addresses, the UPF shall:
当被请求开始报告UE MAC地址时，UPF应：
- report immediately any UE MAC addresses (and possibly their associated VLAN tags) known to be associated to the PDU session (e.g. if the request to start monitoring of traffic is received after the PFCP session establishment and if the UPF monitors the UE MAC addresses for the routing of DL traffic);
-立即报告已知与PDU会话相关联的任何UE MAC地址（以及可能与其相关联的VLAN标签）（例如，如果在PFCP会话建立之后接收到开始流量监控的请求，并且如果UPF监控用于DL流量路由的UE MAC地址）；
- report new UE MAC addresses (and possibly their associated VLAN tags) that are detected subsequently;
-报告随后检测到的新UE MAC地址（以及可能与其相关联的VLAN标记）；
- report UE MAC addresses (and possibly their associated VLAN tags) that are removed subsequently from the PDU session, based on the detection of absence of traffic during the Ethernet Inactivity Timer, if this timer is provisioned in the URR.
-如果在URR中设置了该计时器，则基于在Ethernet Inactivity Timer期间检测到的无流量，报告随后从PDU会话中删除的UE MAC地址（以及可能其相关VLAN标记）。
NOTE: Numerous UE MAC addresses can be used by a same PDU session. The UP function can defer a bit the reporting of newly detected or removed UE MAC addresses to allow the reporting of multiple UE MAC addresses in a same usage report. Details are implementation specific.
注意：同一PDU会话可以使用多个UE MAC地址。UP功能可以稍微推迟报告新检测到或删除的UE MAC地址，以允许在同一使用情况报告中报告多个UE MAC地址。细节是特定实现的。
