Abstract

The present disclosure relates to a terminal positioning method, apparatus, electronic device, and storage medium. The method can be applied to at least one spatial reference device in a space where a terminal is located. At least two subspaces can be included in the space where the terminal is located that are respectively provided with at least one position sensing device. Further, the spatial reference device is a device that satisfies a preset position condition among the position sensing devices. The method can include performing a first communication interaction with a terminal to be located based on a first communication protocol, determining a first relative positioning result for positioning the terminal based on a result of the first communication interaction, and determining a target subspace where the terminal is located based on the first relative positioning result.
