Research on Network Convergence Architecture Design and Optimization for Satellite Communications Combined with 5G

This paper discusses the network architecture design and optimization for the convergence of satellite communications and 5G, aiming to build an integrated network with seamless coverage to achieve the advantages of wide-area coverage and efficient bearer. By analyzing the convergence application scenarios, such as hybrid multicast, kiosk and cell backhaul, this paper proposes a network architecture scheme for the convergence of satellite communications and 5G, emphasizing the importance of network integrity and lightweight design. The specific scheme includes the cooperative work of the ground centralized control center, satellite terminals and satellite mobile core network. In order to optimize the network performance, this paper proposes a number of optimization strategies, such as network delay processing, redundancy coverage and area division, and verifies the effectiveness of the scheme through simulation analysis. The study shows that the optimized network architecture can significantly reduce the network packet loss rate and access user delay, improve the overall communication quality, and provide an important reference for the future development of communication networks.
