Abstract:
A method for determining a change in a distance, a location prompting method and an apparatus and a system thereof are provided. The method includes: sending, by a receiving terminal, a paring request to a server for the server to forward the paring request to a transmitting terminal, and to allocate a frequency band for the receiving terminal and the transmitting terminal after the transmitting terminal accepts the paring request; acquiring, by the receiving terminal, an acoustic wave signal of a frequency sent by the transmitting terminal, wherein the frequency is determined by the transmitting terminal based on the allocated frequency band; determining, by the receiving terminal, a change in the acquired acoustic wave signal; and determining, by the receiving terminal, a change in a distance between the transmitting terminal and the receiving terminal according to the change in the acquired acoustic wave signal.

Claim (Index 5):
The method according to  claim 1 , wherein another one or more frequency bands are allocated to the receiving terminal and the transmitting terminal by the server and the acoustic wave signal of the frequency sent by the transmitting terminal comprises acoustic waves of frequencies respectively corresponding to the two or more frequency bands that are superimposed together.
