METHOD AND SYSTEM FOR CALCULATING LOCATION INFORMATION

摘要

Method and system for calculating relative location information based on a Secure User Plane Location (SUPL). The method comprises: obtaining a location value of a user terminal and a location value of a target terminal in a SUPL-based location information system; calculating relative location information (e.g. a relative distance between the user terminal and the target terminal, direction, etc.) between two terminals based on the obtained location values; providing the calculated relative location information to the user terminal.
