摘要
摘要:针对接入与回传一体化小基站场景下用户个性化视频流业务需求问题,该文提出一种基于接入与回传一体化小基站的用户满意度最大化算法。该算法首先根据系统实际可达速率和用户满意度需求速率间的不匹配程度,动态调整下一周期队列传输所需频谱资源,并建立用户质量满意度最大化模型,其次运用Lyapunov优化方法把初始问题转化为Lyapunov偏移加罚项的优化,将溢出概率约束转化为关于自变量的不等式,最后基于拉格朗日对偶分解的用户接入带宽分配算法和基于内点法的回传和接入带宽分配算法进行求解。仿真结果表明,该算法提高了系统用户质量满意度,同时保证了系统稳定性。

Abstract:To meet the personal quality requirement of video streaming service under the access and backhaul integrated small base station scene, a user satisfaction maximization algorithm is proposed. The algorithm adjusts dynamically the spectrum resources used for next-cycle queue transmission by analysis the mismatch degree between the actual system reachable rate and user satisfaction demand rate. The corresponding optimization model of the quality satisfaction of all users is established. Then, the Lyapunov stochastic optimization method is used to transform the initial problem into drift plus penalty, the overflow probability constraint is transformed into inequality of variables. Finally, using the proposed user access bandwidth allocation algorithm based on Lagrange dual decomposition and the backhaul and access bandwidth allocation algorithm based on interior point method. The simulation results show that the algorithm can improve the quality satisfaction of all users and ensure the system stability.
