Abstract

The embodiment of the invention provides a positioning method and device, a terminal, access network equipment and core network equipment. The positioning method comprises the following steps: the terminal in an idle state or an inactive state receives a positioning paging message sent by the access network equipment; the positioning paging message comprises an identifier of the terminal and idle state or inactive state positioning request information; positioning measurement is carried out in an idle state or an inactive state; according to the embodiment of the invention, when the terminal is in the idle state or the inactive state and only has the positioning service, the network notifies the terminal to carry out the positioning service through the positioning paging message, and the terminal does not need to enter the connected state and directly carries out positioning measurement and calculation in the idle state or the inactive state.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method, device, terminal, access network equipment and core network equipment. Background technique [0002] In the prior art, LMF (Location Management Function, location management function) is a positioning server, which is responsible for selecting a positioning method and triggering corresponding positioning measurement, and can calculate the final positioning result and accuracy. NG-RAN (5G Radio Access Network) can send positioning reference signals, or perform positioning measurements based on assistance information. The terminal device can send a positioning reference signal, or perform positioning measurement based on the auxiliary information, and can also calculate the final positioning result and accuracy based on the measurement result. [0003] The positioning capability in LPP (LTE Positioning Protocol, LTE positioning protocol) includ...
