Design And Implementation Of A Mobile Police Client Software

With the rapid development of wireless mobile communications and various types of fast-growing mobile services, all businesses on the Internet and mobile communication systems applied.With the type of client devices, more and more personalized service people have become increasingly demanding, personalized information services into the future development of Network Information Service is an important direction. Police pass the identity authentication protocol and systems, network security pass in the mobile police occupy a very important position, research and analysis related to identity authentication protocol, designed to secure authentication protocols and systems, is to ensure the safety of police communications pass the necessary conditions, has a very important practical significance.Based on the customer's specific needs, based on J2ME is designed and implemented a mobile police-pass system. The system's overall structure, design and implementation of server-side functions and system to achieve such a detailed introduction. First, according to Mobile police pass the system's security requirements, comparison of existing solutions, systems technology development using J2ME client, using the MVC pattern design to the client. The use of J2ME technology, mobile phone network features to achieve between the client and server communication, using Servlet technologies on the server from the client the information sent to the corresponding processing, transmission of data, return the result. Design and implementation of a base I J2ME/J2EE platform and GPRS networks, outdoor efficient, real-time on-site information gathering, transmission and processing of wireless applications-mobile police system. Its goal is not to replace the existing security system, but to further expand and strengthen the public security system, reducing the public security staff to work outdoors, a negative drop-and improve their work efficiency, but also with the existing security systems to seamlessly integrate well. On the police system is a wireless mobile-specific security needs of mobile police designed a new system. He handheld computers, mobile phones and other handheld devices as the carrier, to achieve real-time field data collection and processing; and to rely on the wireless wide-area data communication network of online search and upload, enabling officers to move in the outdoors can also be handling cases, which greatly improved the efficiency of front-line police officers and power.Of course, there are areas that need improving. We J2ME client MIDlet using the standard components, but because of its versatility, appearance is not very good, but extends MIDlet custom component is also a very time-consuming work. Future system expansion J2ME game structure may be used to achieve the interface, thus achieving a greater ability to customize.
