Research Of LBS Technology In CDMA Network

In recent years, as the CDMA (Code Division Multiple Access) mobile communication network is constantly devloping and the number of CDMA mobile users is continuously growing, the CDMA network of mobile positioning services LBS(Location Based Service) based on CDMA mobile communication network gradually appeals to the crowd as a value-added service provided by the CDMA mobile communication network and the position service based on CDMA technology is also widely concerned by the Telecommuniction provider.The paper is just about the CDMA network of mobile positioning services LBS(Location Based Service), making an intensive analysis of the system function of Sichuan CDMA network of mobile positioning services, it focuses on applying the innovativeness and exploratory of the CDMA network of mobile positioning service technology.Firstly, it summerizes the CDMA network of mobile positioning service system, including the growing background of the LBS and CDMA, the main locating technology of the CDMA, the condition of the CDMA network of mobile positioning services.Secondly, taking the actuality of mobile and communication industry into account, this paper analyzes the requirements of CDMA location services, including the analysis of GIS(Geographic Information System)system functional requirements, functional analysis of local access subsystem. GIS system functional requirements are mainly processing the data source, GIS services, publishing applications, usage of GIS services, GIS management functions and so on. Local access subsystem functions are mainly Location Services CP/SP access management, CP access authentication, routing, parsing the request, local GIS provision, billing functions etc. On this basis, we raise the overall design framework of Location Service System within CDMA. Design framework shows the significance and lead role of Sichuang Location Service System all over the national network.Finally, under the complete framework, this paper further proposes a concrete technical solution to Location Service System within CDMA. This solution consists of two parts, the first part mainly discusses technical solution to GIS system platform for Location Service within CDMA; Another part verbosely expounds access technical solution from local to sub-system of Location Service System within CDMA. In the technical solution to GIS platform, we expatiate on system logic structure of GIS platform, function structure of GIS system, software architecture of GIS system and technical design implementationon functional modules of GIS system. In the second part, we describe system logic structure, function structure, functional module design, software architecture and so on. Specially, we concentrate on expounding the design for access module from local to sub-system, meanwhile, the paper gives opinions on applying the CDMA network of mobile positioning service technology and outlooking on the further direction of research of the CDMA network of mobile positioning service system.
