Study on charging aspects for time sensitive networking
The present document studies the charging aspects for the support of Time Sensitive Networking based on requirements from TS 22.261 [2] and TS 22.104 [7] of 5G system and vertical domains, the architecture, functional and protocol to enable Time Sensitive Communication and Time Synchronization, described in TS 23.501 [3], TS 23.502 [4], TS 23.503 [5], TR 23.734 [6] and TS 24.519 [8].
The following are studied:
- possible charging scenarios and requirements for 5G System integration as a bridge in TSN network;
- possible charging scenarios and requirements for the Time Sensitive Communications and Time Synchronization service;
- possible new charging aspects for the following key items:
- QoS requirements for TSN (e.g. support for TSC QoS Flows, QoS mapping from TSN QoS information to 5GS QoS profile);
- Edge computing scenario support in TSN Transport (e.g. DS-TT and NW-TT);
- charging enhancement (e.g. new triggers) due to policy control for TSN traffic which may impact the charging;
- potential charging solutions for the above charging scenarios and requirements and taking in account TSN application requirements (e.g. instance survival time).
