| The rapid growth of Mobile Internet requests hi-speed asymmetric package data service, so that 3GPP R5 introduces HSDPA (High Speed Downlink Packet Access) As TD-SCDMA is the 3G wireless standard with Chinese independent intellectual property rights, TD-HSDPA is TD-SCDMA based 3.5G wireless access technology. The mass deployment of TD-HSDPA gives great historical significance to Chinese Telecom industry, and it becomes the only choice to China Mobile. The key to business success is how to quickly build the efficient high-quality TD-HSDPA at low cost in the balance of Coverage, Capacity, Quality of Service.So the reseach on TD-HSDPA Planning has important significance for China Mobile.In this paper, firstly Chinese Mobile Market situation and trends of global interrelated technologies are analyzed, and necessity for the construction of TD-HSDPA is pointed out.And then, the impact of coverag,capacity and Iub for the introduction of TD-HSDPA is deeply analyzed. Through the coverage capable of various channels in different networking modes is fully compared, the process and methods of HSDPA network coverage planning is found out. Through the carrying capacity of different allocation of carrier and time slot is deeply analyzed, the process and methods of HSDPA network capacity planning is found out. Through analysis of. the Iub interface protocol and computing bandwidth requirements,three estimation methods for different stages of network construction are recommended.Finally, through the practical network planning utilizing the methods and configuration principle proposed in this paper, the correctness and applicability is verified.. |
