With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 is the flow chart according to an embodiment of the method for the carrier frequency that automatically closes up of the present invention.As shown in Figure 1:
Step 102, in system's free time section of setting, the BSC appointment carrier frequency obturation under the light sector of will loading.
Step 103, the system busy free time section of loading and weighing or enter setting when the sector, BSC solution are closed under the sector by inaccessible carrier frequency.Wherein, a plurality of carrier frequency are arranged under the sector.
In system's free time section of setting, the appointment carrier frequency obturation that BSC will load under the light sector comprises: in system's free time section of appointment, when if the carrier frequency of sector load N continuous time satisfied load hangs down judgment condition, think that then the carrier frequency load of sector is low, then carrier frequency is set to " shutting down " state, and carrier frequency does not allow to insert any new user in " shutting down " state following time.Wherein, set in advance the order of inaccessible carrier frequency.When system was CDMA 1X, the low judgment condition of load is: the forward direction equivalent channel of (forward direction equivalent channel number/(the carrier frequency number-1 that the sector can be used) that the sector the is total)＜=carrier frequency that automatically closes up was counted thresholding.According to one embodiment of present invention, automatically close up that to count thresholding be the threshold value that mode system's setting, that can adopt the carrier frequency that automatically closes up is automatically carried out the forward direction equivalent channel number of inaccessible carrier frequency for the forward direction equivalent channel of carrier frequency.When system was EVDO, the low judgment condition of load was: the number of users thresholding of (number of users/(the carrier frequency number-1 that the sector can be used) that the sector the is total)＜=carrier frequency that automatically closes up.According to one embodiment of present invention, the automatically close up number of users thresholding of carrier frequency is the threshold value that mode system's setting, that can adopt the carrier frequency that automatically closes up is automatically carried out the number of users of inaccessible carrier frequency.
If being set to has the user on the carrier frequency of " shutting down " state, after users such as BSC finish conversation, inaccessible carrier frequency again, and carrier frequency can not insert new user.During users such as BSC finish conversation, if the heavy condition of load is satisfied in the sector, then end to arrange " shutting down " state.
According to one embodiment of present invention, if after carrier frequency is by obturation, this carrier frequency satisfies the condition that the load major punishment is determined, and is then closed by the carrier frequency of obturation by the reverse order solution of obturation according to target carrier frequency; Wherein, when system was CDMA 1X, the judgment condition that load is heavy was: the carrier frequency number that total forward direction equivalent channel number/sector, sector can be used＞the forward direction equivalent channel of carrier reinsertion is counted thresholding automatically.When system was EVDO, the low judgment condition of load was: the number of users thresholding of number of users/automatic carrier reinsertion of sector available carrier frequencies number＞DO that the sector is total.Be in normal operating conditions if only remain a carrier frequency under the sector, even if then this carrier frequency satisfies the condition of automatically closing up, BSC also will ignore and not carry out the operation of automatically closing up.
According to one embodiment of present invention, system is in specifying the free time section, and all sectors of intermittent scanning arrange " the number of times thresholding of the carrier frequency that automatically closes up "=600, specifically refer to trigger the maximum times of opening the carrier frequency that automatically closes up in the time period that arranges.For example automatically close up time period of carrier frequency of the unlatching that arranges now is 0:00-6:00, so during the 0:00-6:00, may reach the number of times of opening the carrier frequency condition of automatically closing up has repeatedly, and the purpose of setting this thresholding limits big maximum triggering times exactly in 600 times.BSC can obtain the channel number of the actual use of each contained fan.By the inaccessible carrier frequency of " the carrier frequency target of automatically closing up frequency sequence " order of appointment, the system of referring to can arrange the inaccessible order of frequency, and the website of three carrier frequency is for example arranged, and site type is 1X S333, DO S333; Unlatching is automatically closed up after the carrier frequency function, by the maintenance console order: MOD BSCRSM order, form is: 242﹠amp; 0,201﹠amp; 0 is arranged to close 242 carrier frequency earlier, and then closes 202 carrier frequency; Then be anti-order when recovering release carrier frequency order; Be arranged to first solution and close 202, solution closes 242 again.By MOD BSCRSM order is set, form is: 242﹠amp; 0,201﹠amp; 0.The heavy thresholding of loading can be set to 40.Suppose to have 3 carrier frequency under the sector of CDMA2000 1X sector A, frequency is respectively 242,201, and 283.Intelligence is inaccessible 242,201.And present actual telephone traffic is 42.According to computational methods, 42/1=42＞40 have then been satisfied the heavy thresholding of load, and solution is closed 201 frequencies automatically.The operation that inaccessible reconciliation is closed can be moved and finish.

BSC31 comprises: the inaccessible unit 311 of carrier frequency, carrier frequency solution are closed unit 312 and carrier frequency load judging unit 313.The inaccessible unit 311 of carrier frequency in system's free time section of setting, the BSC appointment carrier frequency obturation under the light sector of will loading.The system busy free time section of loading and weighing or enter setting when the sector, carrier frequency solution are closed unit 312 solutions and are closed under the sector by inaccessible carrier frequency.A plurality of carrier frequency are arranged under the sector.Carrier frequency load judging unit 313 is judged the low and heavy of carrier frequency load.In system's free time section of appointment, when if the carrier frequency of sector load N continuous time satisfied load hangs down judgment condition, 313 of carrier frequency load judging units judge that the carrier frequency load of sector is low, 311 carrier frequency in the inaccessible unit of carrier frequency are set to " shutting down " state, and carrier frequency does not allow to insert any new user in " shutting down " state following time.Set in advance the order of inaccessible carrier frequency.When system was CDMA 1X, the low judgment condition of load is: the forward direction equivalent channel of (forward direction equivalent channel number/(the carrier frequency number-1 that the sector can be used) that the sector the is total)＜=carrier frequency that automatically closes up was counted thresholding.When system was EVDO, the low judgment condition of load was: the number of users thresholding of (number of users/(the carrier frequency number-1 that the sector can be used) that the sector the is total)＜=carrier frequency that automatically closes up.If being set to has the user on the carrier frequency of " shutting down " state, after inaccessible unit 311 users such as grade of carrier frequency finish conversation, inaccessible carrier frequency again, and carrier frequency can not insert new user.During inaccessible unit 311 users such as grade of carrier frequency finished conversation, if the heavy condition of load is satisfied in the sector, " shutting down " state was then ended to arrange in the inaccessible unit of carrier frequency.If after carrier frequency is by obturation, carrier frequency load judging unit 313 judges that these carrier frequency satisfy the condition that the load major punishment is determined, and then the carrier frequency solution is closed unit 312 and closed by the carrier frequency of obturation by the reverse order solution of obturation according to target carrier frequency;
When system was CDMA 1X, the judgment condition that load is heavy was: the carrier frequency number that total forward direction equivalent channel number/sector, sector can be used＞the forward direction equivalent channel of carrier reinsertion is counted thresholding automatically.When system was EVDO, the low judgment condition of load was: the number of users thresholding of number of users/sector available carrier frequencies number＞automatic carrier reinsertion that the sector is total.Be in normal operating conditions if only remain a carrier frequency under the sector, even if then this carrier frequency satisfies the condition of automatically closing up, the inaccessible unit 311 of carrier frequency also will be ignored and not carry out the operation of automatically closing up.
According to one embodiment of present invention, mobile communication system comprises BSC as above.
Fig. 4 is the schematic diagram of measuring power in the communication system of one embodiment of the invention.Shown in Fig. 4:
System comprises: BSC41, base transceiver station BTS42, general supply 43, LMT44, and clamp meter 45.Open intelligence and close the switch of power amplifier characteristic, dispose automatically close up carrier frequency target frequency, opening time section.Revise the carrier frequency target frequency that automatically closes up of carrier frequency, time started 1:00 when not busy, concluding time 7:00 when not busy (this time will be determined with reference to the traffic situation that existing network is opened carrier frequency), configuration is automatically closed up, solution is closed thresholding.Always import the power supply place in the base station and hang clamp meter, the real-time current in each week before and after statistical property is opened, the total power consumption after estimated performance is opened preceding, characteristic and opened respectively with this, and relatively draw the energy-saving effect that characteristic is opened a week.The instrument of test voltage generally can be voltmeter commonly used, and the Common Instrument of measuring current is that pincers are failed to be sold at auction.Recommend the clamp meter of use.Because most of clamp meters can clamp the record of flow data automatically, removed from and manually removed the cost read.Concrete grammar is: carry out the test of voltage and current in the power supply input port of base station-48V, if base station equipment itself is not-48V power supply that then the voltage and current test point should be tested at the delivery outlet of-48V power supply unit.Through test, use this method can reduce the consumption of power supply.Therefore proved the technical scheme of using the idle carrier frequency of the present invention by closing the base station, can reduce transmitting power, and can play the effect of power saving.According to one embodiment of present invention, the total energy consumption by weeks before and after ten website characteristics choosing are opened compares, and finds that intelligent power output amplification opens the average total energy consumption in back and can reduce approximately 11%, and the part website can reach 30% energy-saving effect.And by test and performance index monitoring checking, it is normal that this characteristic is opened the every index of back website.Because it is little to consider that this energy consumption before and after characteristic is opened of transmission and rotating ring equipment changes, so the electric current of characteristic before and after opening changes the energy-conservation part that just can represent the base station, and the rotating ring monitoring just can realize reading current indication at machine room, the saving great amount of manpower.
