Positioning method and device and storage medium

The invention provides a positioning method and device and a storage medium, relates to the technical field of communication, and can improve the safety in a positioning process. The method comprises the following steps: a positioning device receives a positioning request message from a gateway mobile positioning center GMLC, and the positioning device determines a target positioning management network element LMF; the target LMF is an LMF used for calculating position information of the to-be-positioned terminal; the positioning device sends first indication information to the AMF, and the first indication information is used for indicating the LMF, so that the AMF determines position information of the to-be-positioned terminal through the target LMF; the positioning device receives second indication information from the AMF, wherein the second indication information is used for indicating the position information of the terminal to be positioned; the positioning device sends a positioning response message
