Method and device for positioning terminal in long-term evolution system

The invention discloses a method and a device for positioning a terminal in a long-term evolution system. The method for positioning the terminal in the long-term evolution system comprises the following steps: calculating the delay of the transmission of signal from the terminal to the station to which the terminal is affiliated according to the synchronous time advance and the delay of the receiving of the signal of the station; determining the distance between the terminal and the station by using the delay of the signal transmission; and determining the position of the terminal relative to the station according to the distance between the terminal and the station and the direction of the incoming wave of the signal of the terminal. The method and the device can be used for positioning the terminal through simple calculation and has the advantages of low cost, low complexity and high positioning precision.
