多运营商频谱共享模型和租赁策略
发布时间：2018-10-26 06:56
【摘要】：传统的静态频谱分配方式难以适应未来无线通信业务的发展需求,可能导致运营商业务和用户服务质量受到限制。针对此问题,该文建立了一个包括频谱租赁服务平台层、运营商层及用户层的多运营商频谱共享模型。在该模型中,多个A类运营商将其多余频谱放置在频谱租赁服务平台,供B类运营商租赁,B类运营商与多个A类运营商既竞争用户又共享部分频谱。该文形成了以各类运营商利润最大化为优化目标,以A类运营商的频谱出租量和B类运营商租赁的频谱种类及数量为优化变量的最优化问题,并求得最优解。仿真结果表明,所提策略在保证用户服务质量(QoS)的同时,显著提高频谱资源利用率,并使运营商利润大幅增加。
[Abstract]:The traditional static spectrum allocation method is difficult to adapt to the development of wireless communication services in the future, which may lead to the limitation of carrier services and user quality of service. To solve this problem, this paper establishes a multi-operator spectrum sharing model including spectrum leasing service platform layer, operator layer and user layer. In this model, a number of class A operators put their excess spectrum on the spectrum rental service platform for class B operators to lease. Class B operators and multiple class A operators both compete for users and share part of the spectrum. This paper presents an optimization problem in which the optimal objective is to maximize the profit of all kinds of operators, and the optimal variables are the spectrum rental volume of class A operators and the type and quantity of spectrum leased by class B operators, and the optimal solution is obtained. The simulation results show that the proposed strategy not only ensures the quality of service (QoS) of users, but also significantly improves the utilization ratio of spectrum resources and greatly increases the profit of operators.
