摘要
A-GPS(Assisted Global Positioning System)是一种通过移动通信网络辅助的全球定位技术,此技术结合了两类位置信息,一类是移动台通过自身GPS接收机获得的,而另一类则是移动台通过移动通信网络获取的。A-GPS技术可以在2G,3G以及未来4G的通信网络中部署应用,移动终端应用A-GPS定位业务,需要增加A-GPS接收机及相应信号处理模块。A-GPS的终端一致性认证,即对于移动终端的A-GPS功能部分进行一致性验证,目前国际上采用的包含A-GPS一致性测试规范有3GPP51.010,3GPP34.171,3GPP34.123,3GPP2C.S0036,3GPP2C.S0059,OMA-ETS-SUPL等,本文对上述规范做了详细介绍。
A-GPS （Assisted Global Positioning System） is based on mobile telecommunication network. In this technology, the location information is combined from two parts. One part is from GPS receiver in UE; the other part comes from mobile network. A-GPS technology could be deployed in 2G and 3G telecommunication networks. If UE supports A-GPS, it should have A-GPS receiver and signal process module. A-GPS terminal conformance test focuses on the UE’s A-GPS part. A-GPS conformance test specifications include 3GPP 51.010, 3GPP 34.171, 3GPP 34.123, 3GPP2 C.S0036, 3GPP2 C.S0059, OMA-ETS-SUPL, and etc.
