Single Message Distribution of Timing Information for Time Synchronization in Converged Wired and Wireless Networks

Future factory automation scenarios require real-time capable communication networks and most recently expose great demand for mobile and scalable communication. A promising solution is the convergence of wired and wireless networks in order to merge the benefits of both wired and wireless technologies. The industry emphasizes TSN and 5G as technologies for future communication networks. The seamless integration of 5G with TSN as virtual TSN bridge is a focus topic of the 3GPP and IEEE standardization groups. However, the distribution of timing information through converged TSN/5G networks has not yet been investigated. In this work, we propose and analyze a single message mechanism for distribution of timing information in converged TSN/5G networks under consideration of 3GPP and IEEE standard documents.
