Publication number: 20220417785Abstract: 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.Type: ApplicationFiled: November 6, 2020Publication date: December 29, 2022Inventors: John Walter Diachina, Marilet De Andrade Jardim, Kun Wang, Kefeng Zhang
