TSN-cellular communication system QoS mapping and RAN optimization based on TSN traffic pattern related information

A method performed for operating a cellular communications system as a virtual Time-Sensitive Networking, TSN, node in a TSN system, comprising:

• at a TSN application function associated with the cellular communications system:
• receiving, from a controller associated with the TSN system, one or more TSN Quality of Service, QoS, parameters for the virtual TSN node;
• and
• providing, to a core network function in a core network of the cellular communications system, the one or more TSN QoS parameters for the virtual TSN node;
• and
• at the core network function:
• receiving the one or more TSN QoS parameters for the virtual TSN node;
• mapping the one or more TSN QoS parameters to one or more QoS policies in the cellular communications system, one or more rules in the cellular communications system, or both one or more QoS policies in the cellular communications system and one or more rules in the cellular communications system;
• and
• applying the one or more QoS policies, the one or more rules, or both the one or more QoS policies and the one or more rules, in the cellular communications system;
• at the TSN application function:
• receiving, from the controller associated with the TSN system, information related to a traffic pattern for the virtual TSN node wherein the information related to the traffic pattern comprises periodicity;
• and
• providing, to the core network function in the core network of the cellular communications system, the information related to the traffic pattern for the virtual TSN node;
• at the core network function:
• receiving the one or more TSN QoS parameters for the virtual TSN node and the information related to the traffic pattern for the virtual TSN node;
• and
• providing, directly or indirectly, at least some of the information related to the traffic pattern for the virtual TSN node to another node in the cellular communications system;
• and
• at the another node in the cellular communications system:
• receiving, from the core network function, the at least some of the information related to the traffic pattern for the virtual TSN node;
• and
• forwarding the at least some of the information to an associated traffic translator such that the associated traffic translator outputs TSN traffic in accordance with the traffic pattern for the virtual TSN node.
