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: 20240080340Abstract: The present disclosure provides a security mechanism to mitigate the risk of trackability of a D2D device engaged in groupcast communication. The security mechanism relies on the introduction of new parameters provisioned to the UE to facilitate the privacy protection of destination L2 identifiers used during group communication. The new parameters allow the UE to change the destination L2 Identifier so that an eavesdropper on the PC5 interface can no longer link several broadcast messages originating from the source UE and pertaining to a specific group.Type: ApplicationFiled: October 5, 2020Publication date: March 7, 2024Inventors: Noamen Ben Henda, Markus Hanhisalo, Monica Wifvesson, Yazid Lyazidi, Shabnam Sultana

Publication number: 20230073658Abstract: Security and privacy mechanisms are provided to protect the L2 identifiers used in groupcast communications over the sidelink (e.g., PC5 interface) without requiring a UE to periodically refresh the L2 identifiers, which may cause extra signaling overhead, increased latency and greater risk of synchronization issues. To prevent tracking of a UE, a group identifier (ID) is used as a source layer 2 (L2) ID in groupcast messages. Additionally, a message authentication code (MAC) is introduced into the group discovery procedure to authenticate the UE sending a group discovery request.Type: ApplicationFiled: February 5, 2021Publication date: March 9, 2023Inventors: Zhang Fu, Markus Hanhisalo, Shabnam Sultana, Noamen Ben Henda
