| Time Division-Synchronous CDMA (TD-SCDMA) is one of the3rd generation international mobile telecommunication standards put forward by DATANG Telecom Group, approved by International Telecommunications Union (ITU) and adopted by the3rd Generation Partnership Project (3GPP).TD-HSDPA is the HSDPA technology of3rd generation mobile communication system TD-SCDMA. This paper researches deeply the network performance and strategy. Based on the traffic models and application scenarios of R4and HSDPA hybrid network, a group of TD-HSDPA networking typical models are analyzed and summarized, four kinds of typical wireless scenarios are formed. For the HSDPA channel characteristics and traffic features, to consider the impact of HSDPA capacity upgrading to the user number, throughput and other indicators, combined with simulation results, impact analysis of network coverage and network capacity is given after the introduction of HSDPA. Through the slot configuration, frequency allocation, power allocation, etc., using the results of the analysis of coverage and capacity, the formulation and analysis of networking strategy is completed, and the evolution of HSDPA network strategy is given.The research production in this paper has successfully applied to development and implement of TD-HSDPA system in Datang Mobile Co.Ltd. |
