  • Publication number: 20220417785
    Abstract: 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.

  • Publication number: 20220377046
    Abstract: 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.

  • Publication number: 20220256393
    Abstract: 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.
