摘　　要：针对包含临近空间平台的天地一体化信息网络无线资源动态管理技术开展研究。首先对包含邻近空间平台的空间信息网络拓扑结构进行建模,分别给出了静态网络和动态网络的结构模型;其次分析了动态组网模型下的队列管理策略,以优先保证重要业务的可靠传输;最后分析了网络移动性管理策略,即从IP地址映射更新成本和位置更新成本两个方面分析移动性管理的成本,提出通过合理的划分IP区域、设计位置更新机制,使得移动性管理成本最小化。The dynamic Radio Resource Management(RRM)is studied for Space Integrated Ground Network(SIGN)including near-space platforms.Firstly,the topological structure of spatial information network including adjacent space platform is modeled,and the structural models of static network and dynamic network are given respectively.Secondly,the queue management strategy under the dynamic networking model is analyzed to ensure the reliable transmission of important services.Finally,the network mobility management strategy is analyzed,that is,the cost of mobility management is analyzed from the two aspects of IP address mapping update cost and location update cost.It is proposed that the cost of mobility management is minimized by reasonably dividing the IP area and designing the location update mechanism.
