The architecture for integration of the 5G with TSN 
is depicted in Figure 220.127.116.11-1
. The SEAL Network Resource Management (NRM) server acts as a TSN AF (defined in clause 5.28.1 of TS 23.501
). TSN CNC (defined in 
) via the NRM-S reference point configures the TSN flows in the 5GS. In this case the NRM-S supports the IEEE 802.1Qcc management protocol. As a TSN AF the SEAL NRM server interacts with the 5GS PCF over the N5 reference point to configure the 5G QoS and TSCAI parameters in the 5GS.
Acting as the TSN AF the NRM server collects 5GS TSN Bridge information by interaction with the 5GS via the N5 reference point, as described in in TS 23.502 Annex F.1
NRM server triggers via N5 the AF request procedure as described in TS 23.502 Annex F.2
5G TSC refers to time sensitive communication service offered within the 5G system (i.e. without integration with a TSN system) by the 5GS for the UEs connected to the 5GS. The architecture for the 5G TSC is depicted in Figure 18.104.22.168-1
. The SEAL NRM server acts as an AF towards the 5G Core Network and performs coordination of QoS flows to fulfill the end-to-end QoS requirements for the UEs involved in the TSC communication. It combines the roles of TSCTSF and TSC CNC (similar to the TSN CNC in the TSN integration case), which means that it controls the allocation of resources of TSC communication within the boundaries of the 5G domain.
Upon request from a VAL server via the NRM-S reference point it configures the TSC end-to-end QoS flows in the 5GS. In line with other SEAL service enablers the SEAL NRM server provides a RESTful interface on the NRM-S reference point. As a TSCTSF the SEAL NRM server interacts with the 5GS PCF over the N84 reference point to configure the 5G QoS and TSCAI parameters in the 5GS.
