N2 - In the core scenarios of sixth generation (6 G) satel-lite-terrestrial integrated networks (STINs), to address the issues of time reference transmission discontinuity, insufficient fault tolerance in dynamic scenarios, and lack of multi-source timing coordination, this paper proposes a multi-tier master-slave-peer integrated time synchronization method. Firstly, based on crosstier timing coordination within STINs, this paper constructs a collaborative timing system anchored by Beidou for global reference and optimized by NTP for local distribution. Secondly, this approach embeds a peer switching mechanism to handle link failures, enabling unified timing across all links from top tier nodes to endpoints. Finally, experimental results demonstrate the effectiveness of the proposal, ensuring temporal consistency in information exchange within STINs while providing technical support for efficient 6G network operation.
