混合接入Femtocell网络激励机制的研究

摘要

Hybrid access can allow unregistered users access Femtocells nearby to improve overall system capacity while guaran-teeing registered users’QoS performance.However,leveraging hybrid access successfully is challenging because Femtocell owners are unwilling to share their resources with macro users.In this paper,an incentive mechanism based on game theory is proposed to do trans-actions between Femtocell owners and macro users. Simulation results show that when Femtocell locates at the edge of a macrocell or densely deployed,under this mechanism,Femtocell owners can get reward while guaranteeing registered users�QoS performance by using hybrid access.Macro users can also achieve performance gains by accessing Femtocells nearby.%Femtocell采用混合接入，可以在保证授权用户QoS性能的同时让非授权用户接入，从而提高系统整体容量。但通常Femtocell拥有者不希望和宏小区用户共享Femtocell资源。针对上述问题，提出了一种基于博弈论的激励机制，让Femtocell拥有者和宏小区用户进行交易。仿真结果表明，在 Femtocell 处于宏小区边缘或者密集部署时，该机制可以让Femtocell拥有者通过采用混合接入在保证授权用户QoS性能的同时获得回报，同时接入附近Femtocell的宏小区用户也能获得性能提升。
