Embodiment 1

[0039] An embodiment of the present invention provides a method for energy saving of a base station, such as figure 1 As shown, the method includes:

[0040] 101. If it is detected that a cell in a normal working state satisfies the cell energy-saving condition, an instruction message to close the cell is sent to the base station energy-saving execution device, and the instruction message includes adjusting the P-CPICH (Primary Common Pilot Channel, Primary Common Pilot Channel) frequency channel) the adjustment step size and / or the adjustment time interval of the transmit power.

[0041] Wherein, the condition of the energy saving of the cell may include but not limited to any one of the following conditions or a combination of any of the following conditions: the load of the cell is lower than the preset first load threshold; or the cell The number of internal user equipment is lower than the preset user number threshold; or the cell reaches the preset time for closing the ...

Embodiment 2

[0062] An embodiment of the present invention provides a method for energy saving of a base station. The embodiment of the present invention takes a WCDMA (WidebandCode Division Multiple Access,) system as an example to specifically illustrate the method for energy saving of a base station; in the WCDMA system, the energy saving control device for a base station is an RNC (Radio Network Controller, wireless network controller), and the base station energy-saving execution device is NodeB (Node Base station, base station) such as Figure 5 As shown, the method includes:

[0063] 501. The RNC detects the load of the cell, and if it detects that the cell in a normal working state satisfies the energy-saving condition of the cell, it determines that the cell needs to be shut down to realize the energy-saving of the base station, and then step 502 is executed.

[0064] Wherein, the cell energy-saving conditions include but are not limited to any one of the following conditions or a...

Abstract

The invention discloses a method, equipment and a system for saving energy for a base station, relating to the communication field and solving the problem of higher probability of dropped call of a user in a process of energy saving of the base station in the prior art. In the method, if detectiong that a cell in a normal working state meets a cell energy saving condition, base station energy saving control equipment sends an indication message of closing the cell to base station energy saving executing equipment, wherein the indication message comprises adjusting step length and / or adjusting time interval for gradually adjusting transmission power of a main common pilot channel; and the base station energy saving executing equipment receives the indication message for closing the cell and reduces the transmission power of the cell main common pilot channel according to the adjusting step length and / or adjusting time interval in the indication message. The embodiment of the invention is mainly used in the process of energy saving of the base station, effectively realizes the energy saving of the base station and reduces the probability of dropped call of the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for energy saving of a base station. Background technique [0002] With the emergence of the global village brought about by informatization, the global economy has gradually entered a flat situation with meager profits, and the information industry is no exception. Therefore, while operators are seeking to expand their market share and business types, which is an open-source operating model, they are also focusing on cost-saving links such as energy saving. At present, the carrier frequency in the cell in the wireless communication network will always be turned on after deployment and operation. When the traffic volume or the number of users on the carrier frequency is small, there will be waste of energy consumption and increase the operating cost. Therefore, the energy-saving performance of the base station will also become a performance improveme...
