随着移动的数据业务的爆炸式增长，毫微微蜂窝技术被认为是提高蜂窝网络移动的服务质量和系统容量的最有效途径。然而，毫微微蜂窝部署的主要问题是找到一个合适的接入控制模式，移动的运营商和用户都愿意采用。在各种接入控制模式中，混合接入模式被认为是最有前途的，因为它允许毫微微小区给予毫微微小区所有者优先接入，而其他公共用户只能在一定的限制下接入毫微微小区。由于所有的家庭基站拥有者都是自私的，如何提供足够的激励，使他们将共享他们的家庭基站资源是一个具有挑战性的问题。为了解决这个问题，我们提出了一个经济的框架，移动的运营商和家庭基站用户的博弈理论分析的基础上。我们还利用收入共享的概念，这提供了一个积极的循环，以维持家庭基站服务。在该框架中，制定了一个家庭基站的游戏中，家庭基站的所有者决定的比例，他们将与公众用户共享的家庭基站资源，而运营商最大限度地提高其利益，通过设置分配给家庭基站所有者的收入的比例。我们分析了博弈的纳什均衡的存在性和唯一性。大量的仿真结果表明，所提出的框架最大限度地提高了运营商的利益，并满足用户的服务需求。
With the explosive growth in mobile data traffic, femtocell technology is regarded as the most effective way to enhance the mobile service quality and system capacity of cellular networks. However, the major problem with femtocell deployment is finding an appropriate access control mode that mobile operators and users are willing to adopt. Among the various kinds of access control modes, the hybrid access mode is considered the most promising because it allows femtocells to give preferential access to femtocell owners, while other public users can only access femtocells with certain restrictions. Because all femtocell owners are selfish, how to provide sufficient incentives so that they will share their femtocell resources is a challenging issue. To address the problem, we propose an economic framework for mobile operator and femtocell users based on game theoretical analysis. We also exploit the concept of revenue sharing, which provides a positive cycle to sustain the femtocell service. In the framework, a femtocell game is formulated where the femtocell owners determine the proportion of femtocell resources they will share with public users, while the operator maximizes its benefit by setting the ratio of the revenue distributed to femtocell owners. We analyze the existence and uniqueness of the Nash Equilibrium of the game. The results of extensive simulations show that the proposed framework maximizes the operator's benefit and satisfies the users' service requirements.
