卫星移动网络是以卫星星座为基本物理架构，通过星际的通信链路形成覆盖全球的天基通信网络。它对社会发展、科技进步以及军队的信息化有着重大的推动作用。由于天网的移动性、通信的偶断性、接入的复杂性以及使用的综合性，都为研制提出了重大的挑战。有必要通过总体概念设计仿真，来进一步验证总体需求、总体方案、关键技术指标和研制的约束条件，形成科学的可行性报告。介绍了卫星移动网络的总体概念，设计了针对天网仿真的平台，并用实例获得卫星移动网络总体概念设计的仿真数据。

The satellite mobile network is a sky-based communication network whose basic physical architecture is satellite constellation, and it covers the global areas with the communication links between the satellites. The satellite mobile network gives great impetuses to social development, scientific and technical advancement and military normalization, and it gives enormous challenge to the researchers because of the mobile character of the sky-network, the unmeant disconnection of the communication, the complexity of the access, and the integration of the use. It is necessary to use the general concept design simulation to validate general requirement, general project, key technical guideline, and resourceful restrictive condition, and then to form a scientific feasibility report. This paper introduces the general concept of the satellite mobile network, and designs a platform that aims at the simulation of the sky-network, and gains the data of the general concept design simulation of the satellite mobile network with some examples.
