Research And Implementation Based On The The J2ME Technology Of Mobile Securities System

With the development of mobile phones, and its function becoming increasinglypowerful, the mobile systems gradually penetrate to all aspects of people’s lives; whilebank interest rates continue to decline and the financial sense of people continue toimprove, the stock contacts people’s concern, who has financial awareness. Andconcerning for the stock market and trading at any time, mobile security system wasborn in season, and becomes a major trading platform for people.Compared to traditional transactions, the main advantage of mobile stock tradingsystem could breakthrough constraints of time and space, it’s convenient and private, itcan use mobile phone to view within the market and trade just in the GSM/CDMAnetwork coverage. Having the aid of mobile network, doing securities investment canbe truly anytime, and anywhere.As the development of mobile communications, the number of users holdingmobile phones and other wireless devices gradually increased, and the rapiddevelopment of the securities business provides a broad space for mobile electroniccommerce development and marketing in the applications on securities industry.Comparing with WAP securities transaction systems with existing, mobile securityapplications building on the GPRS, have advantages of strong compatibility and fullyusing existing2.5G network, and it has a very portable embedding in3G networkcommunications in the future.Applying J2ME(Java2Platform，Micro Edition) technology in mobile securitysystems has obvious advantages, firstly, Java language is able to run cross-platform, thatmeans the third-party software developers can easily interfered in developingapplications, but also can be easily installed to the mobile terminal, and also can supportdynamic downloading of applications and upgrades; Secondly, J2ME provides HTTP,TCP and other high-level network protocols, and it makes mobile phones access to allexisting securities consultation information on the internet and all securities tradinginformation provided by security operating directly. It is to meet the securityenvironment in the2.5G/3G user access to securities information quickly and efficiently, the demand for secure transactions, programs to protect the company’s pre-existingsecurities investment in technology and equipment Basis, provided the original C/Ssystem seamlessly.This thesis concretely realize the system on mobile communication devices mainlythrough the J2ME programming technology; and test the connection between systemand the server, the speed of data exchange and reliability in actual data.
