Research Of The Remote Load Technology On The Wireless Terminal

With the rapid development of computer technology and wireless communicationtechnology, feature terminals, intelligent terminals have become increasingly diverse.Meanwhile, for the repairability, reliability and maintainability of the prominentterminal equipment, the R&D companies have introduced a variety of loadingtechniques, such as OTA technology. While the wireless terminal loading techniques,such as domestic independent innovation SCDMA dedicated wireless systems, Theauthor has an in-depth analysis of the domestic market situation and its prospects forthe development, and proposes the wireless terminal remote load technology scheme,Its cost and practicality, technology and business competitiveness are significantly improved.All of which have broad market and potential applications. development andapplication of extremely important significance.This paper on the general design adopt the transactional design andmodularization design method, The paper first outlines the codes loaded technology,then introduces the current wireless SCDMA terminal load design network pattern andthe realization principle. Then the paper describes DMT file which is designed in theXML language. Detailed discussion of the DM state machine drive and terminal-sidecode to load the overall principles, And designs the function of the breakpoint tocontinue transmission and under network abnormal state processing; Secondly, thepaper describes the message exchange process and the relationship between tasksmodules on the code load; In order to guarantee the system higher reliability, Thebreakpoint continued transmission on the function, the network abnormal state andeach kind of complex factor all are corresponded by case processing. So the severaltechnical elements is the key.The remote load software test, in accordance with the requirements of thedemand for software design, overall design, develop critical test sets, define the testingphase. And test results in graph form, data output, show the loading technologyactivities. Finally, It appraised the code load realization effect, summarized theresearch and development success and failure, outlook and explore the load subsequentdevelopment path.
