Document Type and Number:
WIPO Patent Application WO/2022/042476
Kind Code:
A1
Abstract:
The present application provides a positioning method and a related apparatus. The method is applied to a mobility management network element. The method comprises: upon knowing that a terminal device needs to be handed over from a first access network device to a second access network device, sending a first message to a location management network element, the first message being used for indicating suspension of positioning measurement for the terminal device; and upon knowing that the terminal device is handed over to the second access network device, sending a second message to the location management network element, the second message being used for enabling the location management network element to send a first positioning request, the first positioning request being used for requesting to perform positioning measurement on the terminal device. By implementing embodiments of the present application, the problem that the positioning measurement of the terminal device fails when the positioning measurement of the terminal device conflicts with handover of the terminal device is avoided, and the positioning measurement of the terminal device is also continued when the handover is completed.
