Abstract

A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user'"'"'s normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed. This reduces the power consumption of the network device.

Claims

1. A base station, comprising:

a receiver configured to obtain an application point and changed number of cell antennas to be applied at the application point, the application point being a system frame number of a modification period of a system message;

a transmitter configured to send a terminal an indication for the terminal to acquire the application point wherein the application point is used for the terminal to detect the changed number of the cell antennas and apply the changed number of the cell antennas at the system frame number of the modification period of the system message; and

a processor configured to apply the changed number of the cell antennas at the system frame number of the modification period of the system message which is a same system frame number for the terminal to apply the changed number of the cell antennas.

2. The base station according to claim 1, wherein the transmitter is further configured to send to the terminal a transmission mode associated with the changed number of the cell antennas.

3. The base station according to claim 1, wherein the processor is further configured to set a transmission mode associated with the changed number of the cell antennas for the terminal.

4. The base station according to claim 1, wherein the transmitter is further configured to:

instruct the terminal to change currently-applying number of the cell antennas into the changed number of the cell antennas.

5. The base station according to claim 1, wherein the processor is further configured to trigger the receiver to obtain the application point and the changed number of cell antennas in accordance with a trigger factor, wherein the trigger factor comprises one or more of:

cell load, a selected time point, or traffic.

6. The base station according to claim 1, wherein the receiver is further configured to obtain the application point and the changed number of cell antennas through a paging message or a radio resource control connection reconfiguration message.

7. The base station according to claim 1, wherein the system frame number of the modification period of the system message is a starting point of the modification period of the system message.

8. A terminal, comprising:

a receiver configured to obtain an application point instructed by a base station, the application point being a system frame number of a modification period of a system message for both of the terminal and the base station to apply changed number of the cell antennas;

a processor configured to detect the changed number of the cell antennas in accordance with the application point and apply the changed number of the cell antennas at the system frame number of the modification period of the system message which is a same system frame number for the base station to apply the changed number of the cell antennas.

9. The terminal according to claim 8, wherein the receiver is further configured to receive from the base station a transmission mode associated with the changed number of the cell antennas.

10. The terminal according to claim 8, wherein the receiver is further configured to acquire a transmission mode associated with the changed number of the cell antennas set by the base station.

11. The terminal according to claim 8, wherein the receiver is further configured to receive an instruction from the base station to change currently-applying number of the cell antennas into the changed number of the cell antennas.

12. The terminal according to claim 8, wherein the receiver is further configured to obtain the application point instructed by paging message or a radio resource control connection reconfiguration message.

13. The terminal according to claim 8, wherein the system frame number of the modification period of the system message is a starting point of the modification period of the system message.
