摘　　要：动态分析待接入D2D用户对的业务需求,结合蜂窝用户的资源占用情况,对系统可利用资源进行统一评估。计算出待接入D2D用户对的分级评估值,结合阈值参数,差异化区分出3种分级控制场景。最后,采用Matlab工具对本算法和之前的模糊聚类算法(包括功控及无功控)进行了仿真对比验证。结果表明,本算法在接入次数累计分布及系统容量等方面有着更均衡的性能提升。Dynamically analyzing the service requirements of the D2D user pairs to be accessed,it evaluates the total system resources available based on the resource occupancy of cellular users.D2D hierarchically evaluating value is calculated to distinguish three hierarchical control circumstances.At last,the Matlab is adopt to verify the performance of this algorithm and the prevailing FCM ones(including power control and non-control),and the results show that this algorithm has the relatively more balanced performance,whether for the cumulative distribution of access counts,or for the system capacity.
