Abstract:
A method and an apparatus for terminal locating in long term evolution system are provided by the present invention, wherein, the method includes: calculating the propagation delay from the terminal to the base station to which the terminal belongs, according to the synchronization time advance of the terminal and the signal reception delay of the base station to which the terminal belongs (101); and determining the distance between the terminal and the base station by using said propagation delay, and determining the position of the terminal relative to that of the base station according to said distance and the direction of arrival of the signal from the terminal (102). By applying the method and the apparatus provided by the present invention, the terminal locating can be achieved with low cost, low implementation complexity, and high precision for location only by using a simple algorithm.
