开头提到了data burst可以由一个或多个 PDU set的多个PDU组成。由此UPF 可以向 NG-RAN 提供End of Data Burst Indication,基于 PCC 规则中的End of Data Burst marking Indication和本地运营商策略,SMF 应请求 UPF 检测data burst的最后一个 PDU,并在DL最后一个 PDU 的 GTP-U header中标记End of Data burst。

目标站在带有PDCP SN的前转GTP-U分组中标识这些分组并且丢弃掉。 在全配置切换之后,当ue需要向上层递交从源小区收到的PDCP SDU时可以不用考虑可能的间隔。对于那些期望在目标站被传输和重传的上行PDCP SDUs,UE要想丢弃是不可能的。 10.1.2.3.2 对于RLC-UM DRBs 在切换中,源站不会前转那些已经完成传输的数据...

The transport network layer is built on IP transport and GTP-U is used on top of UDP/IP to carry the user plane PDUs between the NG-RAN node and the UPF. Figure 4.3.1.1-1: NG-U Protocol Stack NG-U provides non-guaranteed delivery of user plane PDUs between the NG-RAN node and ...
