Td-scdma System Traffic Performance Analyzing Base On The Datas Of Trials

TD-SCDMA one of 3G standard was submitted by china manufactory in 1998. For validated TD-SCDMA system performance of coverage and capacity and mobility, Some institution organized a series of test and trial.AS a system manufactory of TD-SCDMA staff, I participated in the test and trail in performance test. My mainly job as below.The professional industrialization testsThe professional industrialization tests network consisted of 10 base stations, and it covered with area 30 sq.km. . That test mainly test the ability of coverage, capability and performance of construct mobile network.Base on the test, It testified that TD-SCDMA system was up to the mustard in multi target. The system can be construcked network with same frequency.The TD-SCDMA large-scale trial networkThe TD-SCDMA large-scale trial network featuring the TD-SCDMA standard in three mid-sized cities, namely Xiamen, Baoding, and Qingdao, in addition to ongoing commercial trials in Shanghai and Beijing. This phase test mainly included with performance test of wireless network, O&M test, the test of mutual carriage of calls between different networks,ect.The phase via three levels loaded test, and validated usability of TD-SCDMA system, and partly validated the coverage ability of TD-SCDMA in different scene.The 2007 enlarged scale trail of TD-SCDMAThe 2007 enlarged scale trail of TD-SCDMA mainly take place in ten large-size cities, Such as Beijing, Shanghai, Guangzhou, Shenzhen, etc. .It also was the commerial trail. This trail was certified that TD-SCDMA syetem can be use as a real network. In three phase test, I was responsibility for analysis the performance of system. Include of capacity of traffic, performance of coverage, mobilety quality. And I also participate in actual testing. But the date that I was use was provided by other colleague. So this paper can analyzed the syetem performance of TD-SCDMA with systemic and all-sided datas.The four fundamental is in my job, as below:1. The testing criterion that made by the authority institution was the standard that be use in my job. And the data be obtain with the professional test instrument. This is the mainly method.2. Made the experience on the spot can realized the traffice quality in true environment.3. Due to there are multiplicity traffic of 3G, So I classify them according to the speed and traffic solutions.4. The compatibility,expansibility and development of system are the mainly aspects.All the conculsion, illuminated the TD-SCDMA system can match for the traffic requirement of 3G.The workpaper will argumentation the TD-SCDMA syetem capability of supporting 3G traffic with methods so you say.
