Abstract: A positioning measurement method and an apparatus are provided. The method includes: after a first network element receives, from a second network element, an indication of obtaining location information of a terminal, the first network element requests at least one access network device to broadcast a message. The terminal starts to send a reference signal upon receiving the message broadcast. The first network element further requests the at least one access network device to measure the reference signal. Upon receiving a measurement request, the access network device measures the received reference signal, to obtain a corresponding measurement result; then sends the measurement result to the first network element. According to the present application, during uplink positioning, a terminal in a non-connected state does not need to re-enter a connected state, thereby reducing a delay for positioning the terminal, reducing energy consumption of the terminal, and improving positioning efficiency.

Abstract: A positioning method and a communication apparatus are provided. In the method, a first base station receives a first request from a positioning management function network element, where the first request is used to request the first base station to indicate to a terminal to measure a positioning reference signal. The first base station sends a second request to the terminal based on the first request, where the second request is used to request the terminal to measure the positioning reference signal. The first base station receives a measurement result, from the terminal, in response to the second request, and sends the measurement result to the positioning management function network element, where the measurement result is used by the positioning management function network element to determine location information of the terminal.

Abstract: Embodiments of this application relate to the field of wireless communication technologies, and provide a communication method and apparatus, to improve accuracy of a positioning result and reduce a waste of resources of a network device. In the method, the network device may receive a positioning information request from a positioning server. The positioning information request may be used to request the network device to configure uplink positioning reference signal configuration information for a terminal device. The network device may send the uplink positioning reference signal configuration information and neighboring cell information to the positioning server. The neighboring cell information may include an identifier of one or more first neighboring cells and/or a measurement result of a measurement quantity corresponding to the one or more first neighboring cells. The first neighboring cell is a neighboring cell of the terminal device.
