Claim 19:
20. A system for determining a time difference, comprising:
a first base station configured to receive a first signal transmitted from a terminal and receive a second signal from a second base station, wherein the first signal includes identity information of the terminal;
the second base station configured to receive the first signal transmitted from the terminal, and transmit the second signal after receiving the first signal, wherein the second signal includes the identity information of the terminal; and
at least one processor configured to:
determine a time duration between the first base station receiving the first signal and receiving the second signal; and
