Abstract: In recent years, the rapid development of global satellite communication networks and the seamless integration of satellite communication networks with terrestrial communication networks have become the focus of attention. In this paper, a satellite network architecture based on mobile edge computing (MEC) is proposed which combine with the current development of the integration of satellite networks and terrestrial networks. First, we analyzed the applicability of MEC in satellite network, and then proposed the satellite network architecture based onMECon the basis of 5Gnetwork architecture based on service By adoptingMECtechnology in the satellite network, network performance can be improved, time delay due to longdistance propagation of satellite networks can be reduced, user experience can be enhanced, and satellite network developmentcan be promoted.

Key words: mobile edge computing, satellite communication network, 5Gnetwork architecture
