Description
Technical field
The present invention relates to the communications field, particularly a kind of method and system of realizing base station energy-saving that compensates by covering.
Background technology
The energy resource consumption of base station equipment has accounted for the energy resource consumption 90% of whole mobile network appliance, and the energy consumption of antenna radio frequency part has exceeded 43% of whole base station equipment energy consumption, the energy consumption that therefore how to effectively reduce antenna for base station radio frequency part is the important problem that operator and equipment manufacturer face.
Total is summed up, and the main challenge that base station energy-saving technology faces has following 3 points:
1. the power savings of current power-saving technology is not good;
2. increased the cost of network operation;
3. when base station enters and exits power save mode, may reduce the KPI(Key Performance Indicator of network, Key Performance Indicator).
Power savings for current power-saving technology is not good: the energy-conservation main method of current radio frequency part is by closing time slot, carrier wave or even closing power amplifier (Power Amplified, PA).Wherein close time slot and carrier wave relatively little for the impact of network, but its energy-saving effect is not obvious in actual test process, its main cause is that multiple carrier waves of community are to share same power amplifier, close merely one of them or multiple carrier wave, and do not close whole power amplifier, caused most devices in whole power amplifier still in running status, therefore energy-saving effect is not obvious.If but whole power amplifier is turn-offed, the power consumption of whole base station can be effectively reduced, but the appearance without the situation of covering of certain community in base station can be caused, experience and network quality thereby affected user.
Cost for having increased network operation: at 3GPP(The3rd Generation Partnership Project, third generation partner program) in the research of R11 standard, energy-conservation (Energy Saving) is an important research topic, for non-overlapped scene, in the time that energy-saving base station need to enter power save mode, can take the shutoff of whole community, can other community adjustment around of Rang Gai community cover parameter (as angle of declination, transmitting power etc.) cover compensation, as shown in Figure 1, B-GWei energy-saving cell, its small area, dash area is compensation community, in the first situation, community A is also compensation community.But the problem that the method exists is, the relevant parameter of the covering of the Yi Ge community normally network planning and network phase configures, automatically adjustment may make the serious negative effect that the network performance of shutting off cells and other communities produces, and from realizing comparatively difficulty of angle.
When entering and exit power save mode for base station, may reduce the KPI of network: when certain community is turn-offed in base station, when allowing other communities compensate by certain strategy, can cause part to activate the situation that occurs call drop, this is mainly because power-save operation need to relate to two elemental motions:
1) capacity that the is covered as community of compensation cell extension oneself provides covering;
2) capacity community enters resting state.
If compensation community and capacity community do not coordinate, thereby so maximum problem is exactly to cause the overlapping interference that causes minizone that covers.This obvious interference may have influence on current ongoing handoff procedure, and causes the failure of switching.Issuable failure scene has two kinds:
[1]. carry out the reception that the interference effect of self compensation community has arrived switching command;
[2]. can have influence on excited users from the interference of energy-saving cell and be linked into compensation community.
The first failure scenarios is contingent for being positioned at the excited users at edge, energy-saving cell, and in this situation, what excited users can not be correct receives switching command, thereby has caused handoff failure.For the second situation, if excited users is positioned at the central authorities of energy-saving cell and also likely occurs, even compensation community has covered this region in this situation, so due to the RSRP(Reference Signal Receiving Power receiving, Reference Signal Received Power) be very high, may cause user terminal can not receive random access feedback messages in its random access procedure, this also can cause handoff failure.
In actual network design, as present CDMA2000(Code Division Multiple Access2000, CDMA 2000) maximum 7 frequencies of conventionally adopting of base station cover a region, WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) at most 4 frequencies of configuration a region is covered, and at TD-SCDMA(Time Division-Synchronous Code Division Multiple Access, TD SDMA) in, adopt N frequency technology, three frequencies in the bandwidth of 5M, are comprised only in time slot 0, on main carrier, transmit broadcast.For LTE(Long Term Evolution, Long Term Evolution) and LTE-A, for also can exist multiple frequency ranges to cover the situation in a region simultaneously.

Mainly describe in the present embodiment base station in the processing procedure of carrying out in power-save operation process, the deployment scenario of network is shown in Figure 7.Fig. 7 has described base station and has entered or exited the impact of power save mode on network topology.Wherein each CDMA20001x EV-DO(Evolution-Data Optimized, Evolution-Data Optimized) base station comprises San Ge community, is made up of respectively three directional antennas, and three directional antennas use respectively independently radio-frequency (RF) power amplification.Wherein in the equipment of base station 1, also comprised compensation antenna, the directional antenna of compensation antenna and coverage cell 1-1 shares a power amplifier, and in the time of non-power save mode, compensation antenna is closed work.In each community, dispose 7 frequencies, when OMC is configured in power save mode, only retain 1 carrier frequency F1 wherein, and all the other 6 carrier frequency need to be turned off.
The schematic diagram of allocating antenna scene when Fig. 8 is the non-power save mode of the present invention.The carrier frequency that now directional antenna 1 and directional antenna 2 are opened is F1, F2 and F3, and compensation antenna cuts out.
Step 1: according to long-term statistics, base station 1 did not substantially have the generation of business within 0 o'clock to 4 o'clock night, therefore management station night 00:00 point send to base station 1 indication that enters power save mode.
Step 2: base station 1 is entering into after power save mode, can close the directional antenna of Serving cell 1-2 and 1-3, the covering area of community 1-2 and 1-3 is served by the community 1-1 that compensates antenna and provide.Therefore base station 1 need to send to base station 2,3,4,5,6 under the adjacent area of community 1-2 and 1-3 following information, to send to base station 5 message as example:
retaining carrier frequency is: F1
Step 3: reside in excited users on capacity carrier frequency in the 1-1 of switching cell, base station and, to basic carrier frequency, after all excited users switch, turn-off the F2 of coverage cell, F3, retains carrier frequency F1.
Step 4: switching cell, base station 1-2 and 1-3 reside in excited users on carrier frequency F1 to F2.After switching, turn-off carrier frequency F1, retain carrier frequency F2, F3.
Step 5: compensation antenna is opened in base station, the frequency that compensation antenna is opened is F1.And revise the neighboring BS relationship of community 1-1, wherein increased adjacent area 3-3,4-1,5-2,5-1,5-2, and send beep-page message by Idle state terminal gravity treatments all in community 1-2 and 1-3 in other communities.
Step 6: reside in F2 in switching cell, base station 1-2 and 1-3, the excited users on F3 carrier frequency, in the 1-1 of community, after all excited users switch, turn-offs the radio-frequency (RF) power amplification of the directional antenna of Serving cell 1-2 and 1-3.
