  • Patent number: 11218987
    Abstract: The present invention provides a method and an apparatus for determining a position of a terminal, and a storage medium. The method comprises: sending first DCI or a paging message to a terminal, wherein the first DCI or the paging message is used for triggering the terminal to send a signal and the transmission of the first DCI is started at a paging moment of the terminal; and determining a position of the terminal according to the signal sent by the terminal. The technical solution solves the problem in the related art that a position of a terminal is determined only depending on an uplink signal sent by the terminal device in a connected state, and can easily determine the position of the terminal, thereby avoiding unnecessary power consumption of the terminal and helping saving power of a terminal device.
