Design and reliability detection algorithm of 5G-TSN cross domain redundant clock

The 5G-TSN integrated network can effectively support time critical industrial applications, achieve real-time communication between all industrial equipment, and has broad application prospects. In existing research, the concept of redundant clocks has not been applied to 5G-TSN integrated networks. Therefore, based on a detailed analysis of the synchronization process between 5G and TSN networks, this paper proposes a multi domain fusion cross domain clock synchronization method. This framework treats 5G networks as TSN bridges, forwarding packets with multi domain timestamps, and proposes a time window detection algorithm(TWD) to detect clock bias across domains. The experimental results show that the algorithm can effectively improve the reliability of the clock.
