With the evolution of mobile communication from 3G to LTE,in a certain period,2G/3G network and LTE will coexist for a long time,the huge number of mobile communication base station becomes the focus of the information and communication industry energy consumption.Construction of low power consumption of green LTE network is the entire social expectations and demands for mobile communications.This paper discusses the LTE green network planning method from the network structure planning point of view.That the relay technology,distributed base station,small area base stations,the whole IP flat network architecture methods and technology in the network planning are used,can enhance the network coverage and capacity,reduce the requirements of mobile network to room,air conditioning and power equipment and other facilities,so as to effectively cut down the construction cost,debase the energy consumption of the network.
