The Development Of Lbs Services Based On The J2me Platform And Gprs System Design

The rapid development of mobile communication technology and the rapid popularization of mobile phone, caused that the mobile telephone users already no longer merely satisfies as necessary along with the place voice service. Suited the market demand the value-add service demonstrates the huge development potential. Along with the construction of the mobile communication mainstream technology commercial network, the mobile data load-bearing capacity has the distinct enhancement. Simultaneously the function and the performance of the mobile terminal are also developing. This all provided the broad space for the rich and colorful value-add service development.80% information of the daily life is about people's location, location information also becomes one of the most desired information for people. LBS is precisely the use of a mobile positioning technology and mobile data communications technologies to provide users with the location of the data value-added information services business. Highly developed today in mobile communications, LBS as an important value-added service get more and more widespread attention.Because of the huge market potential, the major global mobile equipment manufacturers are carrying out relevant research and development about LBS. For operators to provide a service platform for mobile location positioning equipment, mobile communications equipment manufacturer has become maintain and expand its market share a strategic tool. In recent years, Ericsson, Nokia, Motorola, Siemens and other mobile manufacturers have launched their own mobile positioning system and developed the Chinese market. Fujian Mobile, Guangdong Mobile has launched or are testing their mobile positioning services, and China Mobile also Tianjin, Changchun, Shenyang, Dalian and other cities launched on STK positioning services. Mobile positioning services in China show a rising trend.This article will focus on the LBS development based on the GPRS system, started in-depth study of LBS network project And on the basis of a detailed understanding of each network function and the flow of various positioning methods, the design of the LBS terminal interface will be carried out, including client and server interface. The service model includes LBS client, LBS server and the mobile terminal. The client is based on J2ME platform and server is based on the J2EE platform.
