Abstract: In order to solve the problem of channel allocation in terminal access satellite network and make full use of the limited satellite network channel resources,on the analysis in the diversity of terminal level and operational level,this paper added the priorities identified,and established the multi-terminal and multi-service priority model.We analysed the relationship among access-satisfaction and the access constrictivity,the link bandwidth and link overall delay,and established access-satisfaction model.The mechanism of channel contention and bandwidth compression was proposed, and then an algorithm of multi-terminal and multi-service priority channel allocation was proposed.The measured results show that,compared with traditional algorithms,the algorithm can allocate the channel resources in different terminals and service levels,thus improving access satisfaction and channel utilization.
