| In 1998 China formally proposed TD-SCDMA technology standard, officially began business in 2009.TD-SCDMA has covered the main areas in major cities across the country after a year of construction. It's will plans to cover the high-speed railway gradually.Consideration from the operator costs, special high-speed rail network covers the two major problem is that the site selection and network formation. From technical point of view, facing the Doppler effect and the rapid convergence of mobile and other problems. Efficient network optimization is a new topic.This paper from the knowledge point of TD-SCDMA network planning, combined with the project of the magnetic network planning and optimization and years of experience in network planning and optimization. First, Summarized method of site selection, antenna construction, network design based on current network for Maglev special network construction. Second, studied and designed the method of analysis magnetic network planning from four part of the capacity, coverage, mobility, interference. In the project , I proposed to use general model by CW testing to analyze the cell radius. By testing proved that the cell radius by General model after correction more accurate than the cell radius by Cost231 model. In handover analysis, I presented that the estimation method of 2 times handover time. Final, I summed up a network optimization plan based on analysis of network planning. Use this method to deliver the project successfully. |
