| The iphone has grown up quickly in recent years. And it led in smartphone market rapidly. It is non-replaceable for China Unicorn’s increasing the percentage of 3G market share. Compared with 2G network,3G network has the distinct advantage of bandwidth. It is the key to occupying the market that Telecommunication Operator should fulfill the advantage of network and provide the applications obtaining approval by customers. Mobile TV is being taken more seriously by Telecommunication Operators as a Killer Application of 3G network. China Unicom built a special nationwide network platform in Mobile TV. And it signed a contract with many TV program suppliers including CCTV, Hunan Satellite TV, SVA, etc. But in the commercial stage of the trial, China Unicom received customer complaint continuously. They said when they watched Mobile TV, the iphone was buffered easily and caused the screen stopping seriously. The article mainly discussed and analyzed the reason for this phenomenon. There are two reasons for the problem. One is the platform, the other is the 3G network. The parameter optimization of 3G network is expounded in detail with the large tests. The article has important significance for Network Optimization.The research job according to the article has been done as following:Deeply study the function of the 3G network parameter for data services, do a great of active tests for this, research the consequence of IRAT HO (Inter-Radio Access Technology Handover) in detail.Organizations all manufacturers to investigate the network platform in Mobile TV, master the cause of the problem by test, resolve the problem.By compared with iphone with common mobile terminal, identify the system of Mobile TV, explain the overall optimization of the business.The thesis is written in order as followed:Unit one introduces the status quo and the development of Mobile TV. Discuss the process and the fundamentality of optimize. Unit two introduces the WCDMA networks synoptically, and explains the theory of IRAT HO. It also introduces the status of Beijing’s network simply, explains the change of Phone status deeply, and introduces the Parameter settings for Ericsson mainly.Unit three explains the structure and application of the network platform in Mobile TV for iphone, and introduces the platform for common mobile simply, makes clear the Internet Protocol for the platform.Unit four explains the Testing processes of the platform in Mobile TV, and makes an analysis of the reason and the result.Unit five introduces the problem of the network, and explains the cause and the Optimization program in detail. |
