The primary goal of 6G mobile communications is to create a ubiquitous access network that includes terrestrial-satellite communications networks. This approach will ensure that satellite networks can deliver multiple services over multiple physical and virtual network components with optimal efficiency and effectiveness. To achieve this, it is essential to allocate a significant number of access resources to ground services through microservices, despite the limitations of satellite resources. This paper proposes an architecture that utilizes microservices as the smallest business unit, allowing for efficient isolation and resource sharing among different business units. A microservice-based terrestrial-satellite integration simulation system has been built to achieve ubiquitous access to the 6G network. The system provides services to various applications through Docker and enables real-time monitoring of container resources.
