The present document studies the charging aspects for the support of Time Sensitive Networking based on requirements from
TS 22.261 and
TS 22.104 of 5G system and vertical domains, the architecture, functional and protocol to enable Time Sensitive Communication and Time Synchronization, described in
TS 23.501,
TS 23.502,
TS 23.503,
TR 23.734 and
TS 24.519.
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).
