Publication number: 20240121686Abstract: A technique for forwarding data packets (730) during a handover of a radio device (100) from a source cell to a target cell of a radio network (702) serving as a time-sensitive networking, TSN, bridge (700) is described. As to a method aspect of the technique at the radio device (100), first TSN data packets (730) are forwarded in the source cell using a first PDU session (704) between the radio device (100) and a user plane, UP (300), of a core network, CN (720), of the radio network (702). Prior to releasing the first PDU session (704), a second PDU session (704) is established (404) between the radio device (100) and the UP (300) of the CN (720) in the target cell, wherein the first PDU session (704) uses a first active protocol stack at the radio device (100) and the second PDU session (704) uses a second active protocol stack at the radio device (100). Second TSN data packets (730) are forwarded in the target cell using the second PDU session (704).Type: ApplicationFiled: February 4, 2022Publication date: April 11, 2024Applicant: Telefonaktiebolaget LM Ericsson (pub)Inventors: John Walter DIACHINA, Marilet DE ANDRADE JARDIM, Claes-Göran PERSSON

Patent number: 11950127Abstract: 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.Type: GrantFiled: February 7, 2023Date of Patent: April 2, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Marilet De Andrade Jardim, Kefeng Kenny Zhang, János Harmatos, János Farkas, Kun Wang, Paul Schliwa-Bertling, Joachim Sachs, Balázs Varga, Maria Belen Pancorbo Marcos, Chunmeng Wang, György Miklós, Shabnam Sultana

Publication number: 20230019215Abstract: 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.Type: ApplicationFiled: January 7, 2021Publication date: January 19, 2023Inventors: Kun Wang, Marilet De Andrade Jardim, György Miklós, Maria Belen Pancorbo Marcos, Shabnam Sultana, Kefeng Zhang

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
