Abstract: Provided are a method and an apparatus for implementing uplink positioning and a storage medium. The method includes: sending a first positioning instruction to a first measurement node set, where the first measurement node set includes at least three measurement nodes and a target node is located within a coverage range of the measurement nodes; receiving first positioning attribute information fed back by each measurement node and corresponding to the first positioning instruction, where the first positioning attribute information includes a measurement node identity and random access information of a cell where the measurement node is located; and sending a random access instruction carrying the first positioning attribute information to the target node, where the random access instruction is configured to trigger the target node to send a random access signal to the each measurement node to determine a communication distance between the target node and the each measurement node.
