Abstract

The introduction of mobile edge computing (MEC) technology in satellite-terrestrial networks can effectively improve the quality of user experience and reduce network redundant traffic

but also brings some challenges.Firstly

the basic architecture of satellite-terrestrial networks and MEC technology was introduced.Moreover

the motivation of introducing MEC into satellite-terrestrial networks and the deployment of MEC were discussed.Then

the architecture of MEC enabled satellite-terrestrial networks was proposed

and the key techniques and typical applications were summarized and analyzed.Finally

the key challenges such as task scheduling and mobility management and some open research issues in integrated networks were summarized.It hopes to provide new ideas for future research in this field.
