Abstract: Based on the research of international standard and the network condition for China Unicom, the basic need for the integrated location-based service platform(ILBSP) is analyzed. Key technologies to realize ILBSP are presented, including the select policy for different location technique and cache function for location process. ILBSP can provide location services to code division multiple access(CDMA) user and global system mobile(GSM) user. This paper proposes a scheme to design and implement the platform including software architecture, hardware architecture and process topology. The scheduling method used by the main module is also presented. And the performance of platform is explained.
