摘　　要：合理的网管信道体制是应急卫星系统实现高效、可靠管理的必不可少的因素。针对应急卫星通信系统的高资源利用率、高传输可靠性和高传输时效性的需求,在综合分析网管信道体制与管理信令基础上,提出了一种多Aloha软件管理方案。该方案将多Aloha技术融入网管软件中,通过中心逻辑识别和载波动态切换实现信息高效传输与资源合理利用。对改进方案传输效果进行了技术分析及仿真,验证了多Aloha软件改造技术的合理性和实用性。Reasonable network management channel system is an essential factor for the emergency satellite system to aehieve efficient and reliable management.Aiming at the high resource utilization, high transmission reliability and high transmission timeliness requirement of emergeney satellite communication system,a multi-aloha software management scheme is proposed based on the eomprehensive analysis of network managenlent ehannel and management signaling. The scheme ineorporates multi-aloha technology into network management software,and achieves efficient transmission of information and rational use of resources through the eentral logic identification and earrier dynamic switching.The technical analysis and simulation experiments are carried out to verfy the validity and practicability of the multi-aloha software reformation technology.
