Terminal positioning method and system for private network

The invention discloses a terminal positioning method and system for a private network, and the method comprises the steps: configuring a positioning network element of a core network of the private network, the positioning network element being composed of an access and mobility management function AMF, a location management function LMF and a network development function NEF; the AMF directly receives a positioning request for positioning the terminal from the terminal or the NEF, and the positioning request of the NEF directly comes from an application function AF outside the core network; the AMF sends a positioning service request to an LMF based on the received positioning request; the LMF responds the generated positioning information corresponding to the terminal to the AMF; and the AMF directly responds to the terminal or responds to the AF through the NEF. Based on the positioning network element and the positioning process provided by the positioning method, the positioning efficiency and the posit
