基于位置信息的流式移动应用推送系统的研究

A location-based streaming mobile application push system

目前与位置相关的移动应用越来越多,传统应用分发模式中,用户需要手动对应用进行搜索、下载、安装以及卸载,不利于提升用户使用应用服务的体验。设计并实现了基于位置信息的流式移动应用推送系统,该系统中服务器利用移动终端位置信息将相关应用解析、安装,并推送到移动终端显示,移动终端根据用户的选择从服务器流式加载应用。该系统使得用户在切换位置时,不用下载、安装即可使用和当前位置相关的应用服务。实验表明,和传统应用分发模式相比,在3G网络环境下可以减少64.37%的应用获取时延,在4G网络环境下可以减少74.49%的应用获取时延。

Now more and more location-based mobile applications emerge. The traditional application distribution mode requires users to search, download, install and uninstall applications manually. Besides, it is not conductive to promote the experience of using application services for users. We design and implement a location-based streaming mobile application push system. In this system, servers analyze and install related applications by using mobile terminal location information and push them to the mobile terminal for display. The terminal loads the applications from servers according to users＇ choice preference. When users＇ locations change, the system enables users to use the application services related to the current location without downloading and installing them. Experimental results show that the system can decrease the latency by 64.37% in the 3G network environment and 74.49% in the 4G network environment in comparison with the traditional application distribution mode.
