A method for controlling positioning integrity. A location management device receives a first message sent by a terminal device, where the first message includes a first parameter set. The first parameter set includes measurement information and/or error information relating to location information of the terminal device. The error information is related to the positioning integrity. The location management device obtains a first positioning result based on the first parameter set and/or positioning assistance data. The first positioning result includes location information and/or integrity information of the terminal device. The integrity information includes the error information and/or alarm information, and the alarm information includes a determining result obtained by comparing the first positioning result with a preset determining condition.

Method for controlling positioning integrity and apparatus

A positioning method includes: a location management device obtains a plurality of assistance data from one or more access network devices, where each assistance data includes one or more groups of mapping relationships corresponding to one or more preset angles, and each group of mapping relationships includes a mapping relationship between each of one or more PRS resource identifiers and power information corresponding to each PRS resource identifier at a corresponding preset angle; the location management device obtains, from a terminal device, power information corresponding to one or more PRS resource identifiers at each of a plurality of to-be-measured angles; and the location management device positions the terminal device based on the plurality of assistance data and the power information.

Positioning method, apparatus, and system

Methods of ascertaining a location of an apparatus, and associated systems are disclosed. An example method includes: receiving, by a terminal device or a chip thereof, a plurality of assistance data including one or more groups of mapping relationships corresponding to one or more preset angles, and each group of mapping relationships includes a mapping relationship between each of one or more PRS resource identifiers and power information corresponding to each PRS resource identifier at a corresponding preset angle. The terminal device determines power information corresponding to one or more PRS resource identifiers which correspond to each of a plurality of to-be-measured angles. The terminal device ascertains its location based on the plurality of assistance data and the power information corresponding to the one or more PRS resource identifiers at each of the plurality of to-be-measured angles.
