Problems solved by technology
[0004] However, after the UE undergoes network handover, the switched core network cannot provide positioning services based on the positioning request managed by the core network before the handover, so the positioning service for the UE cannot continue

The present application provides a terminal positioning method and device. According to this method, after the first network element determines that the target terminal device is handed over from the first core network to the second core network, the first information is sent to the second network element of the second core network and the second information is sent to the third network element , the first information is used to indicate that the second network element manages the location request, the second information is used to notify that the location request is managed by the second network element, and the third network element is used to support a service corresponding to the location request. With the above design, when the target terminal device is switched from the first core network to the second core network, the first network element can instruct the second network element in the second core network to manage the positioning request of the target terminal device, and notify the second network element The positioning request is managed by the second network element of the three network elements, so that after the target terminal device is switched to the second core network, the second network element can continue to manage the positioning request, so that the positioning service corresponding to the positioning request can be continued.
Description
technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a terminal positioning method and device. Background technique [0002] At present, the terminal equipment (UE) network handover is performed between the 4G (4th-generation) evolved packet core network (evolved packet core, EPC) and the 5G (5th-generation) core network, so that the UE can realize the transition from the 4G communication system to the 5G A communication system, or a network handover from a 5G communication system to a 4G communication system. [0003] In addition, the current 4G EPC and 5G core networks both support positioning services for UEs. For example, the client can send a positioning request to the UE through the core network where the UE is located. The positioning request can be used to request the location information of the UE. For example, the positioning request can be It is used to request to obtain the location informati...
