Design Of Wirelesss Positioning System About Location Based Service

Location information service in social life, the role of each industry is more and more important, application of positional information scheduling is more and more common. As mobile communication and wireless location of development, through the mobile positioning technology and geographic information system (GIS), to provide users with the combination of interactive position information has become the general trend. This article through to the northern city of actual investigation, formulate the modified base station sector Numbers (id) Cell-and global positioning system (GPS) positioning of combining the method of implementing personnel and vehicles scheduling command.This paper first discusses the importance of location services, the comparison of several mobile positioning technology method and the applicable scope, introduce their respective advantages and characteristics. Through the investigation and research, puts forward to civil urban range based on mobile signal measured models as well as base to determine its location in the mobile place GSM network position, suburban empty regions adopt GPS signals auxiliary positioning way to identify personnel and vehicles locations. Application mobile field testing of GSM mobile and unicom honeycomb village and map city Cell-id distribution, establishing base foundation database, application of electronic map as the foundation, the design base station village transmission interface and GPS data input interface, constructing GIS location command system.This paper pioneered the north of the city for the first time use base station sector number (ID) CELL phone-combined with GPS positioning scheme design. The project was the first city of wireless community based research across operators, breaking the single GSM operators network covering investigation, brought a downtown China Unicom and China Mobile GSM network base station sector of the actual overlay circumstance. We fully utilize the operators of signalling private network, and our own Intranet interworking is to make full use of advantages, urban broadband transmission network, and making full use of the advantage of various units of information resources has made an example.
