Study on enhancement of Ultra-Reliable Low-Latency Communication (URLLC) support in the 5G Core network (5GC)
The objective of this Technical Report is to study and perform an evaluation of potential architecture enhancements for supporting URLLC services in 5G System (5GS). Specifically, the following aspects are covered:
- Investigate the key issues for meeting the URLLC requirements on latency, jitter and reliability in 5G System as defined in TS 22.261 [5].
- Study how to minimize the impacts of UE mobility to the latency and jitter between AN and CN, and within CN.
- Study how to realize transmission with reliability higher than the reliabilities of single user plane tunnel of N3 and N9 and NFs in the user plane path.
- Study how to monitor the QoS of the QoS flow with URLLC requirement.
- Study potential impacts to charging and policy control.
