Systems and methods are disclosed herein that relate to Time Sensitive Communication (TSC) to Fifth Generation (5G) Quality of Service (QoS) mapping and associated QoS binding. In one embodiment, a method for QoS mapping in a 5G System (5GS) for a virtual Time Sensitive Networking (TSN) bridge comprises, at a first network function, obtaining information from a TSN Application Function (AF) comprising baseline TSC QoS parameters and one or more additional parameters comprising either or both of: (a) one or more additional TSC QoS attributes and (b) one or more additional traffic attributes. The method further comprises, at the first network function, generating one or more Policy and Charging Control (PCC) rules based on the obtained information and providing the one or more PCC rules to a second network function. The method further comprises, at the second network function, performing QoS binding based on the one or more PCC rules.

TSC-5G QoS mapping with consideration of assistance traffic information and PCC rules for TSC traffic mapping and 5G QoS flows binding

Systems and methods for Quality of Service (QoS) mapping based on latency and throughput are provided. A method performed by a first node for mapping Time-Sensitive Networking (TSN) streams includes: receiving traffic class specific information for one or more TSN streams; and determining a set of one or more 5G QoS flows to support the traffic class. This provides solutions where 5QI table entries configured by a 5GS can result in underproviding or overproviding the payload capacity made available to support the traffic class. If less payload space is provided, then TSN stream payload corresponding to the traffic class will be lost. If more space is provided, then radio interface resources will be used inefficiently. As such, the solutions identified herein allow for more efficient use of radio interface resources associated with a 5G QoS flow used to support a set of TSN streams corresponding to a TSN traffic class.

QoS mapping

Systems and methods are disclosed herein that relate to Quality of Service (QoS) mapping in a cellular communications system that operates as a Time Sensitive Networking (TSN) bridge. In one embodiment, a method of operation of a Session Management Function (SMF) in a cellular communications system that operates as a bridge for a TSN system comprises obtaining a QoS mapping table that maps TSN traffic classes to QoS flows within the cellular communications system and distributing at least a part of the QoS mapping table to a User Plane Function (UPF) or a TSN Translator (TT) at the UPF side. In this manner, QoS mapping is provided. Corresponding embodiments of an SMF and a network node that implements an SMF are also disclosed. Embodiments of method of operation of an Application Function (AF) and corresponding embodiments of an AF and a network node that implements an AF are also disclosed.

TSN and 5GS QoS mapping—a user plane based method

Methods and apparatuses for logical time sensitive network (TSN) bridge are disclosed. According to an embodiment, a session management node receives, from a mobility management node in a mobile network, a first request for establishing a protocol data unit (PDU) session for a terminal device which is associated with a port of a logical TSN bridge. The session management node obtains a first port number of the logical TSN bridge at the side of the terminal device. The session management node obtains configuration information of the logical TSN bridge at a side of a user plane node corresponding to the PDU session.

Systems and methods related to Time-Sensitive Networking (TSN)-cellular communication system Quality of Service (QoS) mapping are disclosed. In some embodiments, a method performed for operating a cellular communications system as a virtual TSN node in a TSN system comprises, at a TSN application function, receiving one or more TSN QoS parameters for the virtual TSN node from a controller associated with the TSN system and providing the one or more TSN QoS parameters to a core network function in a core network of the cellular communications system. The method further comprises, at the core network function, receiving the one or more TSN QoS parameters, mapping them to one or more QoS policies and/or one or more rules in the cellular communications system, and applying the one or more QoS policies and/or the one or more rules in the cellular communications system.

A method and apparatus for local application server discovery in edge computing. A method at a network node comprises determining whether one or more domain name system (DNS) servers in an edge computing of a network are available for a user equipment (UE) based on at least one of local configuration information, the UE's current location, the UE's capability or the UE's user subscription. The edge computing is close to the UE. The method further comprises in response to a positive determination, sending, to the UE, a first message including respective address of the one or more DNS servers in the edge computing of the network.

Systems and method are disclosed herein that relate to support for virtual Time-Sensitive Networking (TSN) bridge management, Quality of Service (QoS) mapping, and TSN related scheduling in a cellular communications system. In some embodiments, a method performed by one or more network nodes of a cellular communications system operating as a virtual TSN bridge of a TSN network comprises providing, to a controller associated with the TSN network, parameters that relate to capabilities of the virtual TSN bridge. The parameters that relate to the capabilities of the virtual TSN bridge comprise a first parameter that defines a clock accuracy of an entity in the cellular communications system that operates gating control for the virtual TSN bridge and a second parameter that informs the controller associated with the TSN network that the virtual TSN bridge or a particular egress port of the virtual TSN bridge is restricted to exclusive gating.
