摘　　要：受限带宽下的网管信令突发碰撞是影响卫星通信系统网管信令传输效率的主要因素。针对窄带宽下信令突发引起的卫星网管信令传输效率低的问题,在综合分析卫通网管系统管理信息传输流程的基础上,对网管信令传输现状进行了仿真,提出了一种网管信令传输优化方案。该方案将Qo S技术应用于卫通网管信息传输,并通过排队调度和流量控制实现信息高效传输。仿真验证及系统实测表明,优化后的网管信令传输能力和效率得到了较大提升,该优化方案在提高卫星系统管理性能方面具有科学性和有效性。Network management signaling burst collision in limited bandwidth is the major factor that affects the efficiency of the signaling transmission of network management system.To solve the problem of low transmission efficiency caused by signaling bursts in narrow bandwidth, the network signaling transmission status is simulated and an optimization scheme for network management signaling transmission is proposed based on a comprehensive analysis of satellite communication network management information transmission process.In the scheme,the QoS technology is applied to the information transmission of satellite communication network management, and efficient transmission of information is achieved through queue scheduling and flow control. Simulation and system test show that the optimized network management signaling transmission capacity and efficiency are greatly improved and the optimization scheme is scientific and effective in improving the performance of satellite system management.
