摘要/Abstract

摘要： 为满足差异化业务场景下不同类型用户的服务质量需求，构建了基于网络切片的无线资源分配模型.为获得最佳资源调度方案，将用户服务质量需求转化为无线资源需求，以系统总速率最大化为目标，构建网络资源管理和分配机理及其优化问题.该优化问题为混合整数非线性规划，直接求解复杂度较高，因此提出了基于拉格朗日对偶理论的解决方案，并给出求解算法.通过与比例公平算法和最大系统容量算法进行对比及仿真分析，证明了所提算法在牺牲了部分公平性的前提下提高了系统容量，并验证了所提算法的有效性.

Abstract: In order to meet the quality of service requirements of different types of users in different application scenarios and improve spectrum efficiency, the wireless resource allocation model is constructed based on network slicing. In order to obtain the optimal resource allocation scheme, the quality of service requirements of users are transformed into the wireless resources requirements, and the wireless resource optimization problem is formulated with the goal of maximizing the total system rate. Since the optimization is a mixed integer nonlinear optimization, the complexity of optimal solution is considerably high. A solution based on Lagrange duality is proposed and the solving algorithm is given. Finally, compared with the proportional fairness algorithm and the maximum system capacity algorithm, the simulation results show that the proposed algorithm improves the system capacity while sacrificing partial fairness, which verifies the effectiveness of the proposed algorithm.

Key words: network slicing, resource allocation, quality of service, spectrum efficiency
