摘要
信关站作为卫星移动通信系统的重要组成部分,承担着空口信号处理、系统运行管理、移动业务交换以及与地面网络互联互通等重要工作。针对在卫星和地面通信融合发展的趋势下,如何提高信关站处理能力和资源利用效率的问题,提出了构建基于虚拟化技术的信关站资源池的平台设计方法,设计了OpenStack的虚拟化管控平台的架构与部署方案,对资源进行实时监控和灵活分配,实现信关站处理单元的动态迁移。最后,对虚拟化平台的负载能力及动态迁移的性能进行了测试,验证了所提方案的有效性与稳定性。
As an essential part of satellite mobile communication system,gateway station provides some important functions,including air interface signal processing,system operation management,mobile service switching,and interconnection with ground network.Facing the development trend of satellite-earth fusion,in order to improve the processing capability and resource utilization of the gateway station,this paper first builds the baseband resource pool of the gateway station based on virtualization technology.Secondly,the architecture design and deployment scheme of virtualization management and control platform based on OpenStack is put forward,which can monitor and flexibly allocate the resources in real time,and realize dynamic migration of baseband processing unit.Finally,the load capacity of the virtualization platform and the performance of dynamic migration are tested,verifying the effectiveness and stability of the proposed scheme.
