Study on 5GS Deterministic Networking (DetNet) interworking
The objective of this Technical Report is to study whether and how to enable 3GPP support for DetNet such that a mapping is provided between the central DetNet controller entity (as defined in IETF) and the 5G system. Mapping involves translation of DetNet traffic profile and flow specification to 5GS QoS parameters and TSCAI. The study also considers which information needs to be exposed from the 5G system to the DetNet controller.
The study scope assumes the following:
- Only IP based DetNet is in the scope of the work; MPLS based DetNet is out of scope.
- DetNet over Ethernet TSN is not in the scope of the work as it can be supported based on existing 3GPP and IETF standards.
- It is out of scope to support for edge DetNet node functions in the 3GPP network.
