Claim 0:
1. A method for determining a position of a terminal, the method comprising:
receiving, by a first base station configured to communicate with other objects via a network, a first signal transmitted from the terminal;
analyzing the received first signal to identify identity information of the terminal;
receiving, by the first base station and via the network, a second signal from a second base station, wherein the second signal is transmitted by the second base station after the second base station receives the first signal;
analyzing the received second signal to identify the identity information of the terminal and identity information of the second base station;
determining a time duration between the first base station receiving the first signal and receiving the second signal;
obtaining, based on the identity information of the second base station, a position of the second base station;
determining a time difference between a first time period of the first signal transmitted from the terminal to the first base station and a second time period of the first signal transmitted from the terminal to the second base station based on a third time period and the time duration, wherein the third time period is a time period of the second signal transmitted from the second base station to the first base station; and
determining the position of the terminal based on a position of the first base station, the position of the second base station, and the time difference between the first time period of the first signal transmitted from the terminal to the first base station and the second time period of the first signal transmitted from the terminal to the second base station.
