一种基于用户满意度的网络接入选择和频谱分配联合优化方法

User Access and Resource Allocation Joint Optimization Algorithm Based on User Satisfaction

文中对异构网络下用户接入选择和网络资源分配的联合优化问题进行研究,在传统资源分配方法的基础上,加上用户对网络的主动选择,侧重考虑用户满意度,建立接入选择和资源分配的联合优化模型。在资源分配之前,让用户根据接入每种网络的概率优先选择接入概率最大的网络,在此基础上网络再调整价格来获得最佳的网络效益。仿真结果表明,文中所提出的联合优化方法在保证了网络效益的同时,又兼顾了用户的满意度。

A user access selection and resource allocation joint optimization algorithm in heterogeneous network is studied. Considering the user initiative selection of the network, especially, the user satisfac- tion, this paper establishes an access selection and resource allocation joint optimization model on the ba- sis of traditional resource allocation method. The access probability of each network is different, users choose the network with the access probability is the biggest before the allocation of resources, then the network can adjust the price to obtain the best network utility. Simulation results show that the method ensures the network utility as well as the user satisfaction.
