毫微微蜂窝概念旨在通过在用户的家庭或房屋中部署超低成本、低功率的第三代（3G）基站，将固定线路宽带接入与蜂窝电话相结合。它使运营商能够开拓新市场，推出新的高速服务和颠覆性的定价策略，以获取有线语音分钟数并增加收入。毫微微小区的主要设计挑战之一是宏小区网络中使用的分层架构和手动小区规划过程不能扩展以支持数百万个毫微微小区。在本文中，一个用户部署的毫微微蜂窝解决方案的基础上，基站路由器（BSR）的平面互联网协议（IP）蜂窝架构，提出了解决这些问题，并提出了解决方案的几个方面进行了讨论。详细介绍了系统的总体概念和关键要求。描述了从最终用户购买到集成到现有宏蜂窝网络的自动配置和自优化过程。然后分析了同信道毫微微蜂窝部署的理论性能，并评估了其对宏蜂窝性能的影响。最后，在宏蜂窝网络中的毫微微蜂窝家庭基站部署的财务分析。结果表明，在城市地区，与纯宏蜂窝网络相比，部署覆盖范围略有增加的可公开访问的家庭基站可以显着降低运营商的年度网络成本（在调查场景中高达70%）。
The femtocell concept aims to combine fixed-line broadband access with cellular telephony using the deployment of ultra-low-cost, low-power third generation (3G) base stations in the subscribers' homes or premises. It enables operators to address new markets and introduce new high-speed services and disruptive pricing strategies to capture wireline voice minutes and to grow revenues. One of the main design challenges of the femtocell is that the hierarchical architecture and manual cell planning processes used in macrocell networks do not scale to support millions of femtocells. In this paper, a user-deployed femtocell solution based on the base station router (BSR) flat Internet Protocol (IP) cellular architecture is presented that addresses these problems, and several aspects of the proposed solution are discussed. The overall concept and key requirements are presented in detail. The auto-configuration and self-optimization process from purchase by the end user to the integration into an existing macrocellular network is described. Then the theoretical performance of a co-channel femtocell deployment is analyzed and its impact on the macrocell underlay is assessed. Finally, a financial analysis of a femtocellular home base station deployment in a macrocellular network is presented. It is shown that in urban areas, the deployment of publicly accessible home base stations with slightly increased coverage can significantly reduce the operator's annual network costs (up to 70 percent in the investigated scenario) compared to a pure macrocellular network.
