    • The present invention provides a method and system for implementing emergency location. The method comprises: a User Equipment (UE) initiating an emergency call, and initiating a SUPL position procedure to a security user plane location platform (SLP); and the SLP obtaining location information of the UE through the SUPL position procedure, and providing the location information of the UE to a location request function (LRF). Using the method, the SUPL position procedure is initiated by the UE when the emergency call is initiated and the SLP is not required to support the Session Initiation Protocol (SIP), thereby simplifying design of the SLP. Furthermore, it is clear to the UE that the UE is a qualified SET, so the location request initiated by the UE can certainly be responded correctly, thereby ensuring successful implementation of the emergency call process.
    • 本发明提供一种用于实施紧急位置的方法和系统。 该方法包括:发起紧急呼叫的用户设备(UE)和向安全用户平面定位平台(SLP)发起SUPL位置过程; 并且SLP通过SUPL位置过程获取UE的位置信息,并将UE的位置信息提供给位置请求功能(LRF)。 使用该方法,当发起紧急呼叫并且SLP不需要支持会话发起协议(SIP)时,由UE发起SUPL位置过程,从而简化了SLP的设计。 此外,UE清楚,UE是合格的SET,所以由UE发起的位置请求肯定能够正确响应,从而确保紧急呼叫进程的成功实施。
