Abstract: In order to solve the problems existing in the deployment and operation of femtocell base stations as well as in the spectrum resource share between femtocells and macrocells，an optimal allocation and pricing strategy for spectrum resources is proposed on the basis of Stackelberg game． By modeling the game between base stations and users，the relationship between spectrum price and user demands is analyzed． Then，by modeling the game between macrocells and femtocells，an optimal strategy of spectrum allocation and pricing in various scenes is proposed for two-tiered hierarchical cellular networks． This strategy allocates spectrum resources between macrocells and femto-cells reasonably，maximizes their utility，effectively inspires operators and owners to deploy femtocell base stations，and promotes the process of green communication．
