Description
Technical field
The present invention relates to the communications field, more particularly to a kind of method and system that base station energy-saving is realized by covering compensation.
Background technology
The energy resource consumption of base station equipment has accounted for the energy resource consumption 90% of whole mobile network appliance, and antenna rf part
Energy consumption exceeded the 43% of whole base station equipment energy consumption, therefore the energy consumption for how effectively reducing antenna for base station radio frequency part is
The important problem that operator and equipment manufacturer face.
Total is summed up, and the significant challenge that base station energy-saving technology faces has at following 3 points：
1. the power savings of current power-saving technology are bad；
2. add the cost of network operation；
3. base station enters and may reduced when exiting power save mode the KPI of network（Key Performance
Indicator, Key Performance Indicator）.
It is bad for the power savings of current power-saving technology：It is to pass through closing that current radio frequency part, which saves main method,
Time slot, carrier wave even close power amplifier (Power Amplified, PA).Wherein close the influence of time slot and carrier wave for network
It is relatively small, but its energy-saving effect unobvious in the test process of reality, its main cause is that multiple carrier waves of cell are
Same power amplifier is shared, it is simple to close one or more of which carrier wave, without closing whole power amplifier, it result in whole power amplifier
In most devices be still within running status, therefore energy-saving effect unobvious.But if turned off to whole power amplifier,
The power consumption of whole base station can be effectively reduced, but appearance of some cell without covering situation in base station can be caused, from
And it have impact on Consumer's Experience and network quality.
Cost for adding network operation：In 3GPP（The3rd Generation Partnership
Project, third generation partner program）In the research of R11 standards, energy-conservation（Energy Saving）It is one important to grind
Study carefully problem, for non-overlapped scene, when energy-saving base station needs to enter power save mode, the shut-off of whole cell can be taken, can be with
Other cells adjustment allowed around the cell covers parameter（Such as angle of declination, transmission power）Covering compensation is carried out, such as Fig. 1 institutes
Show, wherein cell B-G is energy-saving cell, and dash area is compensation cell, and in the first scenario, cell A is also compensation cell.
But this method the problem of existing is that the parameter that the covering of a cell is related is typically the network planning and network phase configuration
Alright, adjust automatically may make negative effect serious caused by the network performance of shutting off cells and other cells, and from
Realize more difficult for angle.
Enter and may be reduced when exiting power save mode the KPI of network for base station：When base station turns off some cell, allow
When other cells are compensated by certain strategy, part activation can be caused the situation of call drop occur, this mainly by
Need to be related to two elemental motions in power-save operation：
1) the capacity cell that is covered as compensating cell extension oneself provides covering；
2) capacity cell enters resting state.
If compensate cell and capacity cell without coordinating, then it is maximum the problem of be exactly can cause covering it is overlapping from
And cause the interference of minizone.This obvious interference may influence whether current ongoing handoff procedure, and lead
Cause the failure of switching.Issuable failure scene has two kinds：
[1] carrys out the interference effect of self compensation cell and has arrived the reception of switching command；
[2] interference of the from energy-saving cell influences whether that activating user is linked into compensation cell.
The first failure scenarios is possible for the activation user positioned at energy-saving cell edge, in this feelings
Under condition, activation user can not be correctly received switching command, so as to result in handoff failure.For second of situation, if
The center that activation user is located at energy-saving cell is also possible to occur, even if compensation cell has covered this in this case
Region, then due to the RSRP received（Reference Signal Receiving Power, Reference Signal Received Power）
It is very high, may result in user terminal can not receive random access feedback messages in its random access procedure, this
It is individual to also result in handoff failure.
In the network design of reality, such as present CDMA2000（Code Division Multiple
Access2000, CDMA 2000）Most 7 frequencies of base station generally use cover to a region, WCDMA
（Wideband Code Division Multiple Access, WCDMA）In at most configuration 4 frequencies to one
Region is covered, and in TD-SCDMA（Time Division-Synchronous Code Division Multiple
Access, TD SDMA）In, N frequency technologies are employed, three frequencies are contained in 5M bandwidth only in time slot
In 0, broadcast message is transmitted on main carrier.For LTE（Long Term Evolution, Long Term Evolution）And for LTE-A,
Multiple frequency ranges to be also present while cover a region.
