1. A non-connected-state uplink positioning method, performed by a terminal device, comprising:
receiving first configuration information from a network device when the terminal device is in a connected state with the network device, wherein the first configuration information indicates a first preset area, wherein the first configuration information indicates a first uplink positioning resource used for the terminal device to send a first uplink positioning signal after the terminal device changes to a non-connected state from the connected state, wherein the first uplink positioning resource is valid for the terminal device sending the first uplink positioning signal in the non-connected state when the terminal device is in the first preset area, wherein the first uplink positioning signal includes location related measurement information;
after the terminal device enters the non-connected state while within the first preset area, sending the first uplink positioning signal previously saved in the connected state via the first uplink positioning resource to positioning devices, for determining location of the terminal device; and
when it is detected that the terminal device is moved out of the first preset area but within coverage of the network device, establishing a Radio Resource Control (RRC) connection with the network device, determining an uplink positioning signal of the terminal device, and saving the uplink positioning signal.
