家庭基站（Femtocell）通常作为对3G、4G宏基站的室内覆盖的补充。它兼容2G、3G、4G网络制式及Wi-Fi热点功能，且具有小范围覆盖效果好、成本低、建设难度小等优点。本文所研究的Iuh接口使用在家庭基站实体（HNB）与家庭基站网关实体（HNB-GW）之间。本文详细分析了Femtocell的接入网网络架构和Iuh接口协议栈及其工作流程，通信单元格式等内容。

As an important complement to 3G and 4G Macro eNodeB for the indoor coverage, Femtocell is compatible with 2G, 3G, 4G network pattern, and even Wi-Fi hotspot. Femtocell has many advantages: better covering effect in limited area, lower cost, less con-struction difficulty. This article studies the Iuh inter-face specification, which is used between HNB and HNB-GW. It analysis HNB access network structure, the control plane protocol of Iuh interface protocol stack and information format.
