Abstract
A positioning method, an apparatus, a storage medium, and a chip are provided, and relate to the field of communication technologies, to position a terminal device that is in an RRC inactive state and that reselects a target access network device. The terminal device in the RRC inactive state may move, for example, move from a first access network device to a cell of a second access network device. After receiving first information from a location management network element, the first access network device may send second information to an access network device. The first information is used to request to determine a reference signal resource for the terminal device, and the second information indicates to determine the reference signal resource for the terminal device.
Claims20
A positioning method, comprising:
- receiving, by a first access network device, first information from a location management function network element, wherein the first information is used to request to determine a reference signal resource for a terminal device;
- and
- sending, by the first access network device, second information to a second access network device, wherein the second information indicates to determine the reference signal resource for the terminal device, the reference signal resource is used by the terminal device to send a reference signal, and the reference signal is used to determine a location of the terminal device.
A positioning method, comprising:
- receiving, by a second access network device, second information from a first access network device, wherein the second information is used to request to determine a reference signal resource for a terminal device, the reference signal resource is used by the terminal device to send a reference signal, and the reference signal is used to determine a location of the terminal device;
- and
- sending, by the second access network device, reference signal resource information to the terminal device.
A positioning method, comprising:
- sending, by a location management function network element, first information to a first access network device, wherein the first information is used to request to determine a reference signal resource for a terminal device;
- receiving, by the location management function network element, a first message from a second access network device, wherein the first message comprises reference signal resource information determined by the second access network device for the terminal device, a reference signal resource indicated by the reference signal resource information is used by the terminal device to send a reference signal, and the reference signal is used to determine a location of the terminal device;
- and
- sending, by the location management function network element to at least one of the second access network device and a neighboring access network device of the second access network device, a message used to request to measure the reference signal from the terminal device.
An access network device, comprising a processor and a communication interface, wherein the processor is configured to perform, through the communication interface, the following content:
