Abstract

Embodiments of the present disclosure provide frequency point changing methods and apparatuses. The method can include: transmitting a first beacon frequency point request message to a first base station, the first beacon frequency point request message comprising first frequency point information, wherein the first base station is enabled to transmit the first beacon frequency point request message to a terminal, and the terminal is enabled to change a beacon frame receiving frequency point according to the first frequency point information in the first beacon frequency point request message; receiving a beacon frequency point acknowledgment message transmitted by at least one second base station; and transmitting a second beacon frequency point request message to the at least one second base station, the second beacon frequency point request message comprising the first frequency point information, wherein the at least one second base station is enabled to change a beacon transmitting frequency point according to the first frequency point information in the second beacon frequency point request message.

3. The method of claim 1 , wherein the beacon frequency point request message further comprises a delay time, and broadcasting the beacon message to all terminals within the signal coverage area of the base station comprises:

acquiring the frequency point information and the delay time in the beacon frequency point request message;

generating the beacon message, the beacon message comprising the frequency point information and the delay time; and

broadcasting the beacon message to the terminals.

4. The method of claim 3 , wherein changing the beacon transmitting frequency point according to the frequency point information in the beacon frequency point request message comprises:

changing the beacon transmitting frequency point to a frequency point corresponding to the frequency point information after the delay time having ended.

5. The method of claim 1 , wherein broadcasting the beacon message to all terminals within the signal coverage area of the base station comprises:

acquiring the frequency point information in the beacon frequency point request message;

generating a delay time;

generating the beacon message, the beacon message comprising the frequency point information and the delay time; and

broadcasting the beacon message to the terminals.

6. The method of claim 1 , wherein changing the beacon transmitting frequency point according to the frequency point information in the beacon frequency point request message comprises:

changing the beacon transmitting frequency point to a frequency point corresponding to the frequency point information.

7. The method of claim 1 , further comprising:

broadcasting the beacon message to the terminals through the changed beacon transmitting frequency point.

8. A frequency point changing apparatus, comprising:
