Research Of Mobile Communication Data Services

The main creativities are the followings:Firstly this thesis introduces that, under the present keen market competition, the China Mobile emphasizes to develop some representative operations such as the mobile Internet , multi-media messages etc, to push forward worldwisly the application of our new data operation services. Here this thesis focuses on one of our typical data service --- WAP service, including some important parts of the WAP gateway which supports the WAP service of Henanmobile, such as the network structure, the software structure, the interface protocals, the charging way, the internet manegement ,and so on.This thesis also introduces another representative data service of Chinamobile -WAP service, MMS service and stream media service, including the network structure of the multi-media message center of Chinamobile and flows of these servicesThe thesis mainly analyses the whole distance connection rates of the WAP service and the multimedia message service, as well as the correlated measures and their effect. Firstly, we analyze the particular (detailed) record of the WAP service in the database, to find out some common places of the error information in the particular record, meanwhile take some data packet from the hosts of the service system to make a further comparison and analysis to find out the key problem and solve it in an optimum way, thus attain our goal of improving the connection rate of KPI and the quality of service. In order to explain the actual application instance of WAP technology in Henanmobile, exhibit the superiority of WAP application, we particularly introduces the Henanmobile network optimized plat that based on WAP application.Through the earlier research and analysis, we discovered that the connection rate failure is mainly caused by SP, terminal, the WAPGW itself, and some other equipment. Aiming at these problems, we list particular analytical ways respectively:(1)the SP reason:First we arrange the problematic detailed record through the URL address, to check whether they have some common places, and then analyze these SP that have large numbers of errors, to find out the commonness of them, and coordinate the SP to do the rectification work.(2)The terminal reason and artificial operation:Against the problematic detailed record to carry on dividing a row preface with the terminal type, to examine whether they have some commonness. To those terminal types which have large numbers of mistakes , we make a sample analysis gradually to find out the common reason of those mistakes, then analyze and optimize them through coordinating with the terminal factory;(3)we arrange the problematic detailed record through the URL address,then aimed at the URL address error which appear most to rearrange by MSISDN number,to see whether there are some user terminal setting mistake( such as WAPGW, MMSC setting mistake, URL visit address input error) or Malicious users,etc.In view of the above situation that causes unsuccessful connection, we propose some suggestions and methods of solution respectively.The thesis discribs another mobile service-General Download Service too. Aimed at the StreamMedia service which users regard most,we introduce its sorts,process,features and also the telphone Tele service.Last,in the conclusion,we introduce the service develop perspective that based on WAP,Mobile Phone News,and conceive the Mobile Tele service base on StreamMedia. We belive that the future of Mobile Data Service will be better and better.
