针对异频组网的双层分级蜂窝网,提出了一种基于纳什谈判解法的最优频谱分配与定价策略,该策略能激励家庭基站采用开放用户组模式,最大化频谱效益。通过Stackelberg博弈建模,分析了频谱定价与用户需求的关系。通过纳什谈判解法,获得了最佳的频谱分配与定价策略,按需地为宏基站与家庭基站分配了带宽资源,定量地分析了家庭基站所提高的频谱效益。仿真结果表明,该策略相比非合作博弈方法,可有效提高运营商以及家庭基站拥有者所能获得的频谱效益,部署家庭基站将提高蜂窝网络的总效益。
針對異頻組網的雙層分級蜂窩網,提齣瞭一種基于納什談判解法的最優頻譜分配與定價策略,該策略能激勵傢庭基站採用開放用戶組模式,最大化頻譜效益。通過Stackelberg博弈建模,分析瞭頻譜定價與用戶需求的關繫。通過納什談判解法,穫得瞭最佳的頻譜分配與定價策略,按需地為宏基站與傢庭基站分配瞭帶寬資源,定量地分析瞭傢庭基站所提高的頻譜效益。倣真結果錶明,該策略相比非閤作博弈方法,可有效提高運營商以及傢庭基站擁有者所能穫得的頻譜效益,部署傢庭基站將提高蜂窩網絡的總效益。

Femtocells can effectively improve the coverage of indoor cellular users.This paper investigates the incentive for the holders of femtocell base stations to add femtocell service and achieve open subscriber group,and discusses the opti-mal spectrum allocation between macrocell and femtocells.The interactions between base stations and users are formulated by a Stackelberg game:The base stations first determine spectrum allocations and pricings of femtocell and macrocell serv-ices,and then heterogeneous users choose between the two services and the amount of resource to request.The relationship between the spectrum price and users’demand is analyzed.The optimal strategy of spectrum allocating and pricing for base stations is proposed based on Nash bargaining solution.The strategy can reasonably allocate spectrum between macrocell and femtocell according to their demands and quantitatively measure spectrum utility improve by femtocell.Meanwhile,the proposed strategy maximizes the profits of both the operator and the holders of femtocell base stations.The simulation results show that the proposed method brings more gains for both operators and the owners of femtocell base stations than the non-cooperative method.Deployments of femtocell base stations dramatically improve the utilities of the operator.
