Applications of economic and pricing models for the user association in 5G networks

文章回顾了经济和定价模型在5G用户关联中的应用,讨论了吞吐量最大化的用户关联,采用分布式拍卖或采用价格更新方案的分布式算法,来实现低复杂度的目标。除了吞吐量的改进之外,用户关联中还需要考虑基站(BS)间的负载均衡和用户的公平性。诸如分布式拍卖,一般定价,效用最大化和拥塞定价等定价模式可很好地满足要求。

The applications of economic and pricing models for the user association in 5G networks are reviewed in this paper.A common objective of the network aims to maximize the total throughput of all users in 5G.Distributed auction or distributed algorithms with price update schemes are used to achieve the objective with low complexity.Apart from the throughput improvement,load balancing among BSs and fairness of users need to be considered in the user association.Pricing models such as distributed auction,general pricing,utility maximization and congestion-based pricing can well meet the requirements.
