Based on BBU in the traffic demands lower period, there are a large amount of idle hardwares to be still in highly energy-consuming state, this hair
The bright energy consumption that base station main equipment is reduced using following two mode:
The power amplifier offset switch adjustment loaded by software control based on time slot services.Power amplifier offset switch, which adjusts, is mainly
The bias voltage of power amplifier is closed or opened, to control the bias current of power amplifier, is finally reached energy-efficient purpose.Do not lead in time slot
In the case that communication service, i.e. dynamic power are 0, the static power for being further turned off power amplifier by closing its bias current is described
Static power is to make power amplifier work in the power of linear region.
Carrier switch adjustment or power amplifier offset adjustment based on network traffic load, the carrier wave are realized by software control
Switch adjusts the operating voltage for closing or opening power amplifier.By assessing the communications traffic load in base station in real time, according to negative
It carries threshold value and obtains court verdict, unwanted traffic carrier is transferred to suspended state, to achieve the effect that power saving.Base station leads to
The assessment of communication service amount level is obtained by monitoring the current idle Traffic Channel number of base station.When the message volume of base station exists
When being consistently less than a certain threshold value in specific time, the carrier wave of bearer service will be transferred to suspended state.According to the logical of each carrier frequency plate
Communication service situation judged, the carrier frequency power amplifier module power amplifier that free time length is more than threshold time is closed, while when to activity
Gap is packaged, and communication service is concentrated to part carrier frequency, can prevent new connection setup first after it is transferred to suspended state
On the carrier wave, then it is transferred to and other does not hang up by the intra-cell user's connection connected on the carrier wave of changing commanders
On carrier wave.After base station communication portfolio improves, i.e., when the communications traffic load of monitoring rises, and is more than certain threshold value, immediately
Pent carrier wave is activated, original carrier wave into suspended state meeting rearming again, to meet high communication industry
The demand of business amount.
In BBU O&M monitoring system of the invention, intelligentized energy efficiency management is further used, i.e. radio resource monitors
And management, the temporal correlation being distributed using communication service optimize channel controller Energy Saving Algorithm and control flow, real-time monitoring
The communication service occupancy and user occupancy situation of cell reach energy-saving mesh by closing the channel BBU or free timeslot
's.
When closing BBU, using the mapping for carrying out board and logical resource, and by way of being reported to channel controller
Complete resource adjustment., will be with the main frequency point allocation of location adjacent cell on same BBU board when local resource is established, auxiliary frequency point minute
Fit on remaining BBU board, when cell load decline to a certain extent, free time BBU board where secondary carrier can be closed.First
Idle carrier wave threshold value in one base station is set, when idle carrier wave is greater than threshold value, idle BBU is carried out down it is electrically operated, when
When idle carrier wave is less than specified threshold, need to have carry out power on operation to BBU in advance.Electricity strategy under BBU is supported simultaneously, and is needed
A series of base band is supported using strategy, is base band allocation strategy first, need to follow compact principle to base-band resource into
Row distribution and release, only to be powered on to the BBU of needs；Secondly, being sentenced according to compact using priciple according to certain threshold value
Certainly, defragmentation will be carried out to the base-band resource used, the power on and off operation to BBU is realized according to the result of arrangement.
Channel controller passes through software algorithm real-time statistics cell load, when local resource light load, base station and letter
Track control unit, which can cooperate, carries out baseband pool carrier wave defragmentation, and carrier subscriber resource is concentrated to target carrier frequency plate.Pass through
The carrier aggregation free time goes out some BBU cards, and electricity is standby under the BBU that base station can automatically get off the free time, to save energy consumption.If load
When increasing and reach certain threshold value, and having the tendency that continuing to increase, channel controller may require that base station the BBU for having descended electricity
It powers on, and is automatically added to spare in resource pool.
And be to prevent from BBU from powering on to be likely to result in network congestion not in time, channel controller of the invention first turns on BBU
Closing function switch may be configured as automatically turning in specific time period；Then channel controller real-time statistics cell load.Work as discovery
Cell load then starts carrier aggregation function by channel controller lower than the resource load lower limit of configuration, and user is carried to part
It is concentrated on wave, and after deactivating and being adjusted, the carrier wave that gets off of free time.Activation carrier number on each BBU card of base station real-time monitoring
Amount, and assess whether that remaining carrier wave can be by doing aggregation operator between BBU, the free time goes out BBU card.Base station is to channel controller report
Accuse the carrier information that can assemble.Channel controller carries out reconfiguration operation to these carrier waves according to the report of base station, to complete
Each traffic carrier resource concentrates deployment as far as possible on the high BBU of priority.The distribution principle of the priority height of BBU is: each small
Area's dominant frequency is as far as possible in same BBU, this BBU highest priority；Secondly it sorts according to the resource occupation height of each BBU, i.e., resource accounts for
With more, then its highest priority；If the occupation condition of several BBU is the same, smaller preferential of slot number where board
Grade is higher.After carrier aggregation adjusts, when on base station discovery BBU there is no when the carrier resource being currently being used, base
BBU is automatically closed in station, to achieve the purpose that economize on electricity.When there is user's access that local resource load is caused to rise, reach the money of configuration
When the upper limit of source, carrier resource that active activation has been deactivated by channel controller.Base station discovery is divided again on the BBU of lower electricity
After having matched carrier resource, the board is powered on automatically, to guarantee network capacity.
The free timeslot closing refers to when cell load declines to a certain extent, passes through the power amplifier for closing free timeslot
Energy consumption is saved, and business is integrated into as far as possible on the same time slot in the conceived case, then closes idle time slot
It closes.The descending time slot of all carrier waves of base station real-time monitoring, and idle descending time slot is closed automatically.When base station finds quilt
When there are data to send demand on the time slot of closing, pent time slot can be automatically opened, restores data and sends.Detailed process packet
It includes:
In user's access, channel controller considers to use fixed carrier priority and slot priorities in resource allocation
Allocation plan, it is ensured that under a cell, user distributes the identical time slot in different carrier waves as far as possible.When load a certain in cell
Wave has and has user's release on business release or carrier wave, then channel controller judges whether the downlink of the carrier wave can reduce downlink
Occupy timeslot number.If it can, channel controller triggers descending time slot accumulation process.
According to the descending time slot priority list of configuration, the time slot of highest priority is taken, the target time slot as aggregation.It is first
First by the user in the minimum descending time slot of priority, it is adjusted to target time slot.When the number of users of the minimum time slot of priority is zero
When, adjust the user in the low descending time slot of preferential level.The rest may be inferred.If there is multiple users in time slot, preferential selection is accounted for
It is adjusted with the user more than resource.It at this time if there is new user accesses, and is first accessed on high priority time slot, as far as possible
Guarantee the free time of low priority time slot.
By process as above, resource can be made to be concentrated on the higher time slot of configuration preference level as far as possible.Base station, which is worked as, to be monitored
There is no data to send demand on those time slots freed out, then its relevant power discharging device can be automatically closed, is somebody's turn to do with saving
