Research And Implementation Of Mobile Communication Technology Based On J2ME

With the high speed development of communication technology, the Vase throat of consuming devices and embeded devices technology development is getting more and more impressive. First ,those devices ,using C language and exclusive operation systems, has slow development ,no ability to dynamic loading application programme. One is that the manufacturer's development ability can't meet the ever-increasingly need of function from clients, the other is that many manufacturers of software can't join in .This results in that the application development is getting more and more difficult, which confines the spread of this kind of device. the solution is not intelligent ,which limits the application of wireless InternetThe visit of mobile phone embeded system to Internet ,mainly based on WAP, only can visit local store area, which puts limit on the application of wireless Internet. The presence of J2ME provides perfect solution to the problems mentioned above.Firstly,there are many studies and analysises about Java technology and the knowledge related MIDP,the establishment of development environments.Secondly,it illustrates important technology problems related mobile devices:event solution, data store,network communication,on the basis of probing into design structure ,relating methods,classes and examples.This article concentrates on many websites with ASP technology,combines with network communication technology to make mobile device communicate with server,breaking through the limitation of that mobile phone visits internet only through WAP,and local store area .Out of the reason of technology and commercial interest.most of cellphone users can't operate directly on data but the function of query.Many developers are misled by idea that cellphone users only can operate on simple function of query ,can't operate on data which is not secret.The design in this article can operate directly on data in the structure of J2ME ,based on HTTP,makes it come to true.This dissertation focuses on MIDP and MIDPlet(MIDPlet:application programme on the basis of API defined by MIDP and CLDC), realizes the communication between mobile devices and network server,and further study on much closer combination of mobile device and network,provides more sophisticated platform for future 3G technology.
