Secure User Plane Location Architecture

这是SUPL2.0协议的架构规范，学习手机移动定位、SUPL、LBS的朋友可以下载阅读。 Secure User Plane Location (SUPL) is an Enabler which utilizes existing standards where available and possible, to transfer assistance data and positioning data over a User Plane bearer, such as IP, to aid network and SUPL Enabled Terminal (SET) based positioning technologies in the calculation of a SET’s position. SUPL includes but is not limited to the definition of a Location User Plane (Lup) Reference Point and corresponding interface between the SUPL Location Platform (SLP) and SET, security functions (e.g., authentication, authorization), charging functions, roaming functions, and privacy functions. SUPL utilizes existing standards where available and possible, and SUPL should be extensible to enabling more positioning technologies as the need arises so that they utilize the same mechanism.
