Research And Implementation Of Data Exchange Middleware Based LBS System

Along with the global Internet and mobile networking in the rapid development of mobile location services (Location Based Service, LBS) have been in such as the city intelligent traffic, vehicle navigation, mobile phone communication, interpersonal communication and many other fields play a very extensive and important effect.LBS system is a set of location data, timely communication, geographical information storage and processing for the integrated information service platform; at present, China's independent research and development of " Beidou satellite navigation and positioning system " is constantly created and began to throw on the market application, it will be LBS business to provide more accurate and more high quality localization services, however at this stage based on Beidou Positioning System and location service oriented extensible data communication platform in the face of massive high concurrent terminal connection requests and data data, often appear processing efficiency is low even complete paralysis of the situation. In addition, in the traditional web application framework and design pattern formation under communication scalability and extensibility are generally poor, this also gave the whole LBS system of stable operation and maintenance more difficult, the existence of these problems makes the LBS system can't meet the actual demand of the market, in addition, due to the user terminal and its related protocol type recently began to use, the market can really support the terminal equipment data communication platform also rarely, therefore, based on the Beidou system oriented LBS data communication platform for research and implementation is very necessary.In LBS system development of middleware technology can not only reduce the complexity of the underlying positioning technology, heterogeneous and coupling, but also can improve the whole LBS system scalability and scalability. Combining the actual application background, with the help of the middleware system thought, serious analysis and study the LBS system middleware, design and implementation of a scalable, high concurrency and high throughput LBS data communication middleware system. The system with asynchronous event driven model as the core, and extensive use of the memory pool, pool, handle pool and other system optimization technology, good to meet the needs of practical application of project performance.
