摘　　要：基于LTE的星地融合宽带通信网兼有卫星网和地面网的互补优势,能实现大范围覆盖,信关站是连接卫星网与地面网络的桥梁。分析信关站硬件平台的功能与性能需求,依据网络处理器、专业多核处理器和Power PC处理器等3种硬件平台,提出适合卫星信关站硬件平台的3种方案,根据不同的应用可选择适合的方案。A converged satellite and terrestrial broadband communication network based on long term evolution（LTE） has the complementary advantages of satellite networks and terrestrial networks. Therefore,it achieves larger coverage. A teleport is a bridge that interconnects satellite networks and terrestrial networks together. Through the analysis of the function and performance requirements of the teleport hardware platform,three schemes suitable for Satellite-Teleport hardware platform are proposed on the basis of the hardware platforms of the existing network processor,professional multi-core processor and Power PC processor. Therefore,suitable solutions can be chosen according to different applications.
