摘要
为解决移动位置信息服务中兴趣点(POI)数据格式不规范、更新周期长的问题,本文提出了一种采用TPEG协议对POI信息进行统一编码,然后借助移动多媒体组播和广播实时广播发布的方法。
To solve the problems that the POI datas lacked of unified specification and effective means of broadcast timely in location-based mobile services, this paper introduced a novel method to embed the point of interest messages into transport protocol experts group and described the implementation of TPEG message broadcasted over MBMS using the stream delivery method.
