Research on Service Pattern and Platform Design of Location Based Common Service on the Basis of Multi-application System

As an important part of GNSS(Global Navigation Satellite System) application,LBS(Location Based Service) is absolutely a fast-growing mobile value-added service.More and more application systems are emerging with the fast developing of LBS.However,LBS application systems are mainly built individually:they integrate both common LBS functions and domain specific functions.Although it ensures the integrity of application systems,it also results in high level of coupling within the system,poor extension ability and waste of resources.This paper gave a discussion about service building and new service modes of Location Based Common Service,which is based on multiple application systems.And the system is divided into two parts under the new service pattern,LBS common service platform and expertise application system,and the LBS common service platform can be shared by multiple application systems.
