Embodiment 1

[0049] In this embodiment, the judgment algorithm of SON energy saving control is judged according to the time period, the energy saving control indication message (ENERGY SAVINGS INDICATION) is used to carry the energy saving control indication, the energy saving control response message (ENERGY SAVINGSRESPONSE) is used to indicate that the processing is successful, and the energy saving control failure is used The message (ENERGYSAVINGS FAILURE) indicates that processing failed, figure 2 It is a flow chart according to Embodiment 1 of the present invention, such as figure 2 As shown, the process includes the following steps 201 to 206, wherein steps 201 to 204 are the processing of the cell sleep, and steps 205 to 206 are the processing of the cell wakeup:

[0050] Step 201, the SON periodically performs energy-saving control judgments, and judges whether the eNodeB cell needs to sleep or wake up according to the decision-making method of the time period, for example, the ...

Embodiment 2

[0057] In this embodiment, the judgment algorithm of SON energy saving control is judged according to the load conditions of the serving cell and neighboring cells, and the number of soft handover attempts. The energy saving control indication message (ENERGY SAVINGS INDICATION) is used to carry the energy saving control indication, and the energy saving control response is used. The message (ENERGY SAVINGS RESPONSE) indicates that the processing is successful, and the energy saving control failure message (ENERGY SAVINGS FAILURE) indicates that the processing fails. image 3 It is a flow chart according to Embodiment 2 of the present invention, such as image 3 As shown, the process includes the following steps 301 to 306, wherein steps 301 to 304 are the processing of the cell sleep, and steps 305 to 306 are the processing of the cell wakeup:

[0058] Step 301, the SON periodically performs energy-saving control judgments, and judges whether the eNodeB cell needs to sleep or...

Abstract

The invention discloses a method and a device for controlling carrier power. The method comprises that: an SON judges whether a cell of a base station needs dormancy and / or wakeup; if the judgment result is dormancy required by the cell, the SON indicates the base station to perform dormancy on the cell so that the base station reduces the pilot channel power of the carrier of the cell to zero or turns off the carrier and the cell enters a power-saving state; and when the judgment result is wakeup required by the cell, the SON indicates the base station to wake up the cell so that the base station recovers the pilot channel power of the carrier of the cell to a working state value and the cell exits the power-saving state. The method and the device can achieve the power-saving and environment-friendly effect of the base station without changing the hardware, ensure that a call of a user is not dropped in the power-saving dormancy state, and ensure quick entry or exit of the power-saving state.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for controlling carrier power. Background technique [0002] At present, the telecommunications industry has gradually entered the meager profit stage. While seeking to expand market share and business types to increase revenue, telecommunications operators are also paying more and more attention to energy saving and other cost reduction links. As a major energy consumer for operators, base stations are the key to energy conservation. At the same time, ordinary people are paying more and more attention to the problem of electromagnetic wave radiation pollution in the working state of the base station. [0003] At present, the energy saving of the base station is mainly achieved by adopting new energy-saving and environmental protection devices and improving heat dissipation materials to reduce the power consumption of the base station and reduce the power c...
