摘　　要：针对未来6G移动通信网络工作频段更高、覆盖范围更小、建网成本更高、带宽需求更大等问题,分析了6G网络多方共建、频谱动态共享的发展趋势,提出了基于区块链的多方频谱动态共享排队论模型,分析了区块链系统区块体长度对区块处理时延、平均队列长度之间的影响,并结合移动通信网络物理资源分配参数、区块链系统处理能力和业务特征,对基于区块链的频谱动态共享场景进行了仿真对比分析。Aiming at the issues of higher working frequency band,smaller coverage,higher network construction cost,and greater bandwidth demand in future 6G mobile networks,this paper analyzes the development trends of multiparty 6G network construction and dynamic spectrum sharing,proposes a blockchain-based multi-party spectrum sharing queuing model is proposed,and analyzes the impact of the block length of the blockchain system on the block processing delay and average queuing length.Furthermore,combining the allocation parameters of physical resources in the mobile communication network,the processing capability of the blockchain system and service characteristics,this paper provides a simulation-based comparison analysis of blockchain-based dynamic spectrum sharing scenarios.
