毫微微蜂窝基站是一种有助于减少移动的网络的资本和运营支出同时增强系统覆盖和容量的解决方案。然而，避免干扰仍然是需要解决的问题，以在现有宏小区网络上成功地部署毫微微小区层。此外，干扰强烈依赖于接入控制的类型，其决定给定用户是否可以连接到毫微微小区。本文将解释现有的毫微微蜂窝基站接入方法及其优缺点。还提供了对毫微微/宏网络中的接入方法的商业模型和技术影响的描述。最后，混合接入方法和几种模型的需要。
Femtocells are a solution that helps to reduce the capital and operational expenditure of a mobile network while enhancing system coverage and capacity. However, the avoidance of interference is still an issue that needs to be addressed to successfully deploy a femtocell tier over existing macrocell networks. Moreover, interference is strongly dependent on the type of access control, which decides if a given user can or cannot connect to the femtocell. In this article the existing access methods for femtocells together with their benefits and drawbacks are explained. A description of the business model and technical impact of access methods in femto/macro networks is also provided. Finally, the need for hybrid access methods and several models are presented.
