Embodiment
In order to solve the higher problem of energy consumption of base station in prior art, the invention provides a kind of base station electricity saving control method and device, below in conjunction with accompanying drawing and embodiment, the present invention being further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
By analyzing the power consumption situation of base station, there is a big chunk power consumption on the radio frequency unit (i.e. radio frequency chip/veneer) except power amplifier.When community is in busy condition, the power consumption of these radio frequency units accounts for about 25% of whole base station power consumption, and when being in " free time " state in community, these radio frequency unit power consumptions account for the proportion of whole base station even more than 70%.Base station energy-saving consumption reduction can be had in mind from here, when radio frequency unit power consumption exceedes a certain proportion (meaning that base station is in idle condition), and deexcitation or lower electric portion radio frequency unit.Below by embodiment, technical scheme of the present invention is introduced.
Present embodiments provide a kind of base station electricity saving control method, the method can realize in base station side, Fig. 1 is the flow chart of the base station electricity saving control method according to the embodiment of the present invention, and as shown in Figure 1, the method comprises the following steps (step S102-step S104):
Step S102, according to the power consumption accounting of each radio frequency unit of base station, judges the current state of base station.
Particularly, this step can be realized by following preferred implementation: if in each radio frequency unit of base station, the power consumption accounting of at least one radio frequency unit is greater than first threshold, in residue radio frequency unit, the power consumption accounting of at least one radio frequency unit is greater than Second Threshold, then judge that base station is in not busy state; Wherein, first threshold is greater than Second Threshold; Otherwise, judge that base station is in busy state.
Step S104, when judging that base station is in not busy state, reduces the number of radio frequency unit.
Particularly, this step can be realized by following preferred implementation: when base station is in not busy state, and N number of radio frequency unit maximum for power consumption accounting is defined as radio frequency unit to be combined; N number of radio frequency unit to be combined is merged into M radio frequency unit, and by electricity under remaining radio frequency unit to be combined; Wherein, N>1,0<M<N.Preferably, in order to ensure MPS process, the transmitting power of M radio frequency unit after merging can be improved.
When judging that base station is in busy state, if in each radio frequency unit of base station, the power consumption accounting of at least one radio frequency unit is less than the 3rd threshold value, then search the radio frequency unit that whether there is lower electricity; Wherein, the 3rd threshold value equals Second Threshold and deducts and prevent pingpang handoff thresholding, and this prevents the numerical value of pingpang handoff thresholding from can determine according to practical operation situation.If the radio frequency unit of the lower electricity of existence, then activate radio frequency unit of at least one lower electricity, and be that the radio frequency unit activated distributes corresponding transmitting power.
Preferably, energy-saving sign (put 1 or set to 0) can be set.After lower electric radio frequency unit, energy-saving sign can be put 1, represent the lower electric radio frequency unit existing and can be activated.When the number of lower electric radio frequency unit is 0, energy-saving sign is set to 0.
When adjusting the transmitting power of the number of radio frequency unit and correspondence thereof, need based on power distributing network, after execution union operation, the number of current radio frequency unit connects directional antenna, then for each directional antenna distributes the transmitting power of correspondence.
By said method, decide to meet the radio frequency unit number needed for MPS process and transmitting power according to the power consumption accounting situation of base station, and be assigned to directional antenna by power distributing network.What this technology did not need consideration base station to adopt is which kind of communication standard and technology.Each radio frequency unit of busy is all opened and full power is launched, and idle can only have a radio frequency unit to launch.Solve the problem that energy consumption of base station in prior art is higher, the power consumption of relevant device can be saved greatly, thus reach the object of base station energy-saving consumption reduction.
Fig. 2 is the system configuration schematic diagram of the reduction energy consumption of base station according to the embodiment of the present invention, and as shown in Figure 2, this system comprises Base Band Unit, radio frequency unit, power distributing network, directional antenna and monitoring backstage.
Base station judges the busy-idle condition of base station according to the power consumption accounting situation of each radio frequency unit current, regulates the radio frequency unit number and transmitting power that use base station.
Power distributing network receives for notifying to hurry/instruction that switches of idle, according to instruction, appointment is needed the radio frequency unit number of work and the transmitting power of numbering and correspondence.
Busy/not busy switching command drops to the triggering of a certain threshold values by monitoring backstage according to each cell power consumption accounting, and this algorithm also will provide the transmitting power of now each radio frequency unit.
Power distributing network is responsible for connecting three width directional antennas (being assumed to be three sectors) according to radio frequency unit work number in instruction, carries out power division.Base Band Unit and radio frequency unit cooperatively interact the modulate emission and receiving demodulation of carrying out data.
The agent structure of power distributing network is made up of merit combiner device and electric-controlled switch.The signal that radio frequency unit sends closes the cooperation of device and electric-controlled switch via merit, can arrive predetermined directional antenna.Electric-controlled switch receives the control information that monitoring backstage is sent by control line, and the path of specifying is opened.
