Research Of Mobile Communication Technology Based On J2ME

With the development of information society, it is imperative that mobile telephones and other mobile wireless devices are linked with the Internet. But there are many disadvantages in the software of conventional mobile telephone. 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 Internet. The visit of mobile phone embed 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, the fundamental theory of developing mobile software is introduced in this that the function and architecture of J2ME, KVM, MIDP. Secondly, it illustrates important technology problems related mobile devices. event solution, data store, mobile communication, on the basis of probing into design structure, relating methods, classes and Examples. Achieved Interactive System Mobile Terminal.This article concentrates on many websites with JSP technology, combines with mobile 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, realizes the communication between mobile devices and network server, and further study on much closer combination of mobile device and network.
