Referring to research on the Heterogeneous Network(Het-Net) application scenario and technique characters in IMT-Advanced(The 4th Generation Mobile Communications) cellular system,this paper provides further analysis on main technique aspects of Heterogeneous Network,discussion on interference issue due to multi-layer building by access points and their corresponding solutions from standardization and engineering implementation. The proposed solution can effectively solve the interference problem in IMT-advanced Het-Net,and also improves the networking performance dramatically for future mobile communication systems.
