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.
