Testing And Analysis Of Mobile Terminals Modem In Wireless Communication Networks

With the rapid development and rapid spread of wireless communication networks,as well as mobile networks operators reduce prices,more and more users use mobile terminals to access the Internet through a wireless communication network,enjoy the convenience of many aspects from the Internet.So wireless communication technology can be seen in at any time any place,and a profound impact our lives.Modem of mobile terminal under high frequency work pressure to help users to transfer information between software layer and the wireless communication network layer.As a core element of wireless communication network interaction,the functionality and Performance and stability of modem have a directly influences on the user experience.In the research and development process,testing not only cover the basic software function and laboratory protocol,but also to focus on a large number of testing cases to analog mobile terminals in a real wireless communication network.Mobile terminals due to various effects of interference source,environmental climate and user traffic in the reality wireless communication network.So mobile terminals have many characteristics: complexity,accessibility,variability,randomness,these characteristics can`t be covered by laboratory protocol testing.So as to more fully and effectively test on the mobile terminals to ensure quality.The theoretical basis is mobile terminal modem signaling process protocol of wireless communication network,analysis of the current network coverage of operators and user experience.Made a number of test cases around voice calls,data throughput,the interaction of multiple services,to form a complete assessment standards of the performance of the mobile terminal modem.So that make up for a lack of product in research and development testing and push the testing process of modem product development became high efficiency.Use a variety of analog test tools for mobile terminals modem to test performance in the real wireless communication networks,including the overall functionality and stability.Through signaling process analysis to monitoring between modem of mobile terminals and the base station to determine whether the performance of the mobile terminal modem correct.Compare the results of the test and the established indicators to judge the performance and stability of mobile terminal modem.In testing procedures have some wireless communication network problems,such as call access failure and call drop,position navigation.Use of test software simulation to survey and analysis these fault cases,final solution to the problems is offered.
