| With the development of economy and society, the communication tariff reduction more and more quickly, the rapid development of business and a variety of proliferation, the behavior of user has changed, the demand for communication has became diversification. Large activity is a country and region economy actual strength, integrated competition ability reflects. TD-SCDMA technology has independent intellectual property rights, studies its activity in large communication security work in network construction, to improve the competitiveness of TD-SCDMA system, enhance the international domestic influence has crucial effect.This paper combine the communication security of Tianhe Sports Center, in accordance with the large scale activity before, during, after three steps to introduce TD-SCDMA network construction related issues.The paper focuses on the implementation of the work before the large scale activity starts, including:1) TD-SCDMA coverage construction. Mainly from the capacity of TD system, planning indoor distribution system of TD-SCDMA system, planning outdoor site,planning frequency, planning emergency.2) network quality improvement. The new road test according to the test, the background operation, data analysis,analysis of the results in several steps described in detail how to improve network quality.3) terminal performance testing. Through the simulation and real TD-SCDMA network based on terminal, performance testing.Then introduced the large-scale activity during communication security includes communication support organization structure, emergency treatment, backup, It also presents the Guangzhou Asian Games opening ceremony on the day of Haixinsha’s successful TD communication security case large-scale activities after the end of the follow-up communications guarantee work of resource utilization are introduced, finally the article analyzes the advantages of TD-SCDMA system and its development and evolution direction. |
