Design And Implementation Of Mobile Phone Positioning System Based On Data Acquisition And Analysis

Along with the rapid development of mobile Internet, location-based services(Location-Based Services, LBS) further rise of mobile applications.3G era, the era ofdevelopment and future4G mobile value-added services to provide a broad space fordevelopment, and mobile location services for its mobility, practicality, at any time andpersonalized features, became the SMS generation, the phone mobile value-addedservices have great potentials for development.Based on the user’s location to provide value-added services, is a means to get bypositioning the location of mobile phones, combined with some other similar electronicmap service platform to provide users with relevant services and the current position,which can be a good business to enhance the user experience sticky, push to thespecified user groups associated custom content, and how to provide mobile users fast,precise positioning results became the basis for subsequent value-added services.The traditional positioning GPS satellite positioning technology can provideaccurate location, but the use of time to first fix up to ten seconds or tens of seconds will,in addition, bad weather conditions,"urban canyons", mobile terminal does not haveGPS service modules, etc. special scenario, would limit the use of positioning function.AGPS, base station location, also has its shortcomings, in order to compensate for theLACk of positioning technology, the major manufacturers have made this innovation,2009Google,2010Baidu have launched a personal location services, locationtechnologies used to produce a further development, the current principal businesslocation technology business model is dependent on mobile terminals featureinformation that will CELL, WIFI, GPS and other mobile terminals underlying data forthe overall mixing process, according to data reported by the terminal effectivelydifferent location data has accumulated through information, data mining, to get thelocation of the end user, the positioning process is divided into off-line and on-linereal-time location data collection in two parts, the guarantee under the premise ofpositioning accuracy, positioning speed has been greatly improved.In this thesis, based on mobile data collection terminal, based on the positioningdata mining research on the positioning system as a whole system for design andimplementation.
