摘　　要：当前的LBS应用系统多采用独立构建方式,将LBS通用服务功能与应用系统相关功能集成,使系统内部耦合程度较高,虽然能够保证应用系统的完整性,但导致LBS通用服务功能难以共享,造成系统的扩展性差以及数据、计算资源的浪费。该文探索了面向多应用系统的位置公共服务(LBCS)的服务模式与系统体系结构。基于这种服务模式,位置服务系统将由两大部件构成:LBS公共服务平台和专业应用系统,且LBS公共服务平台能被多个应用系统使用。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.
