摘要:

移动定位服务(LBS)是一种新兴的无线增值业务,能够利用无线网络为移动用户提供基于位置的信息服务,具有巨大的市场潜力。LBS系统平台的好坏直接关系到商业运营的质量。本文从应用部署的实际出发,利用J2EE中的Facade模式来设计系统平台,从而可以避免接入层与业务层出现紧耦,使得系统各模块的开发更加高效、灵活。通过测试证明了该平台设计的可行性,能达到商业运营的基本要求。

关键词: 移动定位服务, 增值业务, 应用服务中间层

Abstract:

Location Based Service(LBS) is a new wireless increment service, which can provide mobile users locationbased information services through the mobile network and has huge market potential. The system platform of LBS has a direct bearing on the quality of commercial services. From the actual conditions of application deployment, this paper expatiates how to design the platform based on the facade pattern in J2EE, which can avoid tight coupling between the accesslayer and the businesslayer and make the module development more efficient and  flexible. A simulation test for the platform has proved the feasibility of the design, which  meets the basic requirements for commercial operation.

Key words: locationbased services;increment service;a middle tier for application services
