With a specific embodiment power-economizing method of the present invention is elaborated below, present embodiment may further comprise the steps:
101, be configured respectively in BSC side and BTS;
Wherein, the BSC side can the configuration feature time point, the following electric switch of cell level.Whether the BTS side can dispose our station and support under the intelligence of veneer.
102, the telephone traffic of BSC detects automatically;
Carrier frequency to the free time descends electricity, and when on the carrier frequency for the treatment of down electricity traffic being arranged, then informing business is moved to the traffic on the current carrier frequency on the carrier frequency of other high priority.
103, the power-on and power-off state of the every T2 periodic report of BTS current carrier frequency and and the corresponding relation (physical logic relation) of physics transceiver unit;
After BSC receives physical logic relation, change if find the physics logical relation, then respond whole carrier frequency to BTS and power on, professional reliable to guarantee, otherwise BSC responds up-to-date carrier frequency power-on and power-off state according to the detection of step 102 to BTS.
104, BTS detects the power-on and power-off state of the logic carrier frequencies that BSC responds and the data of current preservation compare, and when the power-on and power-off state of logic carrier frequencies changes, judges then whether our station supports intelligence electricity down, if support that then execution in step 105; If do not support that then execution in step 103.
105, the carrier frequency of the carrier frequency of these power-on and power-off of BTS and power-on and power-off before has change, and then the power-on and power-off state of the logic carrier frequencies of responding according to BSC carries out peripheral single board power on operation or electricity operation down.
107, the electric current journey finishes under the peripheral single board, carries out the detection of next cycle.
Further, BSC has corresponding judgement at the power-on and power-off of the carrier frequency in the residential quarter, and the flow process of step 102 also comprises:
102.1, the performance measurement data that reports of the every T1 cycle detection of BSC BTS, measurement data comprises the telephone traffic of every line, but in order to prevent changing frequently, the design anti-trembling function, whether dispose the permission switch of electricity down every K1 time period detected cells, switch opens is just carried out the following electric treatment of carrier frequency, otherwise all carrier frequency of residential quarter all power on.
102.2, the telephone traffic of every line is lower than down electric switch limit N1 in the residential quarter, the carrier frequency of selecting (perhaps whole) from this residential quarter descends.
The telephone traffic of described every line equals telephone traffic/number of available channels.
If the carrier frequency for selected electricity down also has the situation about taking of calling out, can arrive not the carrier frequency of electricity down to call migration according to client's demand.
102.3, the telephone traffic of every line does not reach down electric switch limit N1 in the residential quarter, but do not reach the thresholding N2 that powers on yet, select (perhaps all carrier frequency) carrier frequency from this residential quarter and power on.
Wherein, N2＞N1.
102.4, the telephone traffic of every line reaches the thresholding N2 that powers in the residential quarter, then is considered as telephone traffic and increases severely, and will initiate promptly to power on, carrier frequency all in the residential quarter is all powered on.
The power-on and power-off cycle of BTS system peripherals veneer is different, wherein BP powers on slower, if the TCH of residential quarter is (Traffic Channel, Traffic Channel) electricity under the BP of carrier frequency association, and BCCH (Broadcast Control Channel, Broadcast Control Channel) carrier frequency is in power-up state, BSC detects telephone traffic to be increased, require TCH to power on, but BP powers on the cycle long, will cause network congestion.Therefore, carry out different processing modes at different peripheral single board.
The electric current journey also comprises under the RRU of step 103 and the veneer of BBU:
103.1, transmitting-receiving letter module (DTRU): when carrier frequency is closed, the transmitting-receiving letter module related with this carrier frequency closed, outside transmitting power.
103.2, the power amplifier (PA) of far end radio frequency: when all DTRU of this PA subordinate close, then this PA closes, and PA opens to have a DTRU to open then.
103.3, LTE Baseband Processing Unit: when certain LTE Baseband Processing Unit BP (being assumed to be BPi, the maximum BP number of i＜system) not related with logical resource, then under the LTE Baseband Processing Unit.Have needs to power in the logic carrier frequencies that BPi binds, then this BPi veneer keeps powering on.The logic carrier frequencies that goes up binding as BPi is all electric down, and down whether the BCCH carrier frequency of residential quarter, decision logic carrier frequency place.
103.3.1, when the BCCH carrier frequency of certain residential quarter CELL (cellular cell, be called for short " residential quarter ") (being assumed to be CELLj, the maximum carrier frequency number that j＜BP plate is supported) need power on, then BPi keeps powering on;
103.3.2, go up the whole electricity down of BCCH carrier frequency of residential quarter at the logic carrier frequencies place of binding as BPi, then under the BPi.
103.3.3, the logic carrier frequencies of on a plurality of BP plates, the binding carrier frequency that electricity down all arranged simultaneously and power on, this moment, any one BP can not descend electricity, considered the BP base-band resource is dynamically adjusted, so that more resources is descended electric less power consumption.
Have electricity and the carrier frequency that powers on down simultaneously if judge the logic carrier frequencies of binding on a plurality of LTE Baseband Processing Unit, judge then whether described LTE Baseband Processing Unit satisfies the condition of adjusting resource, as satisfying, then the following electric carrier frequency on power on carrier frequency and other LTE Baseband Processing Unit on one or more described LTE Baseband Processing Unit is exchanged, till the carrier frequency that do not power on described one or more described LTE Baseband Processing Unit, close described one or more described LTE Baseband Processing Unit then.
Dynamic resource adjustment flow process comprises among the step 103.3.3:
103.3.3.1, judge whether satisfy to adjust the condition (namely judging whether to have the situation that BP can following electricity) of resource;
Judgment principle in the present embodiment is: deduct the difference of the carrier frequency number P that ought all power on as all resource S of BP greater than Q (Q is the maximum carrier frequency number that a BP plate is supported), then think to have possibility electric under the BP.
In the present embodiment, with the binding relationship of logic carrier frequencies and RRU and BP copy copy, judge with copy that adopting copy to judge can be so that data rewind swap fault the time can not have influence on current binding relationship.
Judging under the condition that satisfies the adjustment resource, the following electric carrier frequency on power on carrier frequency and other BP on one or more BP is exchanged, till the carrier frequency that do not power on described one or more BP, close described one or more BP then.Method was carried out the adjustment of resource below present embodiment adopted:
103.3.3.2, inquire about maximum and minimum two BP (being assumed to be BPi and BPj) of carrier frequency that existence powers in all BP plates
103.3.3.3, do not reach thresholding M when the load of BPi, with among the BPi down among the carrier frequency of electricity and the BPj not down the carrier frequency of electricity (comprising not the resource with the logic carrier frequencies binding) exchange in advance, judge whether the load of BPi this moment reaches thresholding M.Do not reach thresholding, then exchange, continue to judge, otherwise the state of record BPi is not commutative, enter step 103.3.3.2 and continue to judge;
103.3.3.4, when the state of all BPi all is set to not commutatively, think and judge and finish, the exchange result of copy is analyzed.
103.3.3.5, when there is under the BP electricity in the exchange result, think that then there is meaning in exchange, upgrade binding relationship, and qualified veneer descend electricity, otherwise think and exchange no any effect, swap fault.Step 103.3 flow process finishes.
Certainly, adjust resource and be not limited to said method, for example, deduct at all resource S that judge BP under the situation of difference greater than Q (Q is the maximum carrier frequency number that a BP supports) of the carrier frequency number P that ought all power on, also the carrier frequency that powers on the BP of Q correspondence can be exchanged on other BP, can directly discharge the BP of Q correspondence like this.
Fig. 5 is the schematic diagram that a gsm system resource status distributes, and as shown in Figure 5, in BBU, main control module is responsible for carrying out associated allocation and the peripheral single board power-on and power-off operation of BSC carrier frequency, base-band resource and radio frequency RRU resource, has assigned the formation tlv triple as figure:

With { Sectori, Trxi} are designated as Rii, and wherein R11 is the BCCH carrier frequency of residential quarter 1, and R21 is the BCCH carrier frequency of residential quarter 2.
For remote radio unit (RRU) RRU1, owing to have only the binding of a physical carrier and logic carrier frequencies, and this logic carrier frequencies is in down, so the PA of this RRU can turn-off, for remote radio unit (RRU) RRU2, the PA of this RRU powers on owing to there is the carrier frequency of binding to be in, so must keep powering on to guarantee that business is normal.For the RF remote resource of RRU1 and RRU2, as long as the carrier frequency of binding is closed condition, then this resource all can be closed.
For BBU, (R11, so R12) electricity down, but R22 electricity down are the electric condition of the discontented foot of BP1 when BP1 goes up the logic carrier frequencies of binding.When the logic carrier frequencies R21 of the last binding of BP2 not descends, also be discontented with the electric condition of foot, all two BP veneers all are in and power on, but because the carrier frequency number that all powers on is 3, the whole available base-band resource 2*Q-3＞Q of BP (wherein, Q is the maximum resource number that every BP supports) are so dynamically carry out the resource adjustment, the adjustment result is shown in Figure 6, and BP1 can descend electricity with consumption reduction after adjustment finished.
