Problems solved by technology

However, this method adjusts the granularity of the entire board too coarsely. When the free frequency point capacity is insufficient to power down a single board, some digital signal processors (DSPs) on the board are actually still running in idle state, so the comprehensive power consumption reduction effect limited

Embodiment Construction

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0045] First, refer to figure 1 , which is a structural block diagram of a system for reducing power consumption of a baseband board of a base station according to an embodiment of the present invention. In the embodiment shown in the figure, the power consumption reduction system of the present invention includes a detection module 2 and a main frequency control module 4 . Since each baseband board contains a plurality of digital signal processors (DSP), each DSP independently processes a frequency point, and each frequency point handl...

Abstract

The invention discloses a method for lowering the power consumption of a base station base band plate. Each base band plate respectively comprises a plurality of digital signal processors. The method comprises the following steps: calculating the amount of users accessing into the digital signal processors of the base band plate; according to the change of the accessing user amount, adjusting frequency / or electrifying and cutting power to the digital signal processors of the base band plate. The invention can use smaller power consumption to adjust granularity to obtain better energy saving effect. The invention also provides a system for lowering the power consumption of the base station base band plate, a frequency modulator, a power-on / power-off device, a main frequency point DSP electrifying rotation device and the like.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for reducing power consumption of a baseband board of a base station. Background technique [0002] With the rapid development of mobile communication, people have higher and higher requirements for mobile communication, and more and more base stations are required, and the capacity of base stations is also larger. In order to increase the capacity of the base station, it is necessary to increase the number of baseband boards to ensure that the base station can still meet the capacity requirements when the number of users is the largest. In fact, the business volume of the base station is different in different time periods of the day, and the business volume between the peak and the underestimation is very different. [0003] At present, after the base station is started, usually, no matter whether the baseband boards carry services or not, they are in th...
