Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment 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 schematic flow sheet of Poewr control method one embodiment of the present invention, comprising:
11: network equipment identification matter difference terminal;
12: the network equipment is determined the interference source of described matter difference terminal;
13: the network equipment reduces the transmitting power of described interference source.
Wherein, the embodiment of the invention can be applied in any wireless associated scenario, and the above-mentioned network equipment can refer to different concrete equipment in different wireless systems, for example, in the 2G system, the above-mentioned network equipment can be base station controller (Base Station Controller, BSC) or the base station (BaseStation, BS), perhaps, in the 3G system, the above-mentioned network equipment can be evolution base station (evolvedNodeB, eNodeB) etc.
Wherein, matter difference terminal can refer to all relatively poor terminals of continuous signal quality, can adopt following any mode to identify:
Mode one: the measurement report that receiving terminal reports, if the credit rating of carrying in 1 measurement report of N continuous all is lower than the setting credit rating, then identifying described terminal is matter difference terminal;
As shown in Figure 2, terminal can be measured the quality of downstream signal, and (Measure Report MR), can carry credit rating in the measurement report to the base station reporting measurement reports.Wherein, the numerical value of credit rating is generally the arbitrary integer between 0～7, and the more big quality that shows of numerical value is more poor.
If it is 7 that the numerical value of the credit rating in 1 measurement report of N continuous can be set, and perhaps is 6 or 7, then identifying corresponding terminal is matter difference terminal.
Mode two: the wireless channel to terminal carries out quality testing, if the credit rating that 2 quality testings of N continuous obtain all is lower than the setting credit rating, then identifying described terminal is matter difference terminal;
Wherein, for upward signal, quality testing can be carried out to upward signal in the base station, obtains credit rating, at this moment, all is for 2 times that credit rating is 7 or is 6 or 7 if the upward signal N continuous of a terminal is detected in the base station, and then identifying this terminal is matter difference terminal.
Be understandable that, mode one and mode two are determined according to descending and up quality testing result respectively, also can be in conjunction with descending and up, for example, 1 descending credit rating of N continuous is set is lower than and sets credit rating and 2 up credit ratings of N continuous are lower than when setting credit rating, then identifying terminal is matter difference terminal.Above-mentioned N1 and N2 can be identical or different.
Mode three: if the down-run survey report is lost M continuously, then identifying described terminal is matter difference terminal;
As shown in Figure 3, if in the measurement report of terminal to report, the base station continuous N is individual does not receive that all identifying this terminal so is matter difference terminal.
Mode four: if RLT-S＞α, then identifying terminal is matter difference terminal;
Wherein, RLT is Radio Link inefficacy count value, is predefined fixing value.The threshold value of α for arranging.S be according to slow associated control channel (Slow Associated Control Channel, SACCH) message whether correct decoding determine that for example, the initial value of S is RLT, during mistake decoding S is subtracted 1, add 2 during correct decoding.
After identifying pledge difference terminal by the way, can further identify the interference source of these terminals, and then reduce the transmitting power of interference source, to reduce the interference to these terminals, avoid these terminal call drops or influence throughput.
Wherein, can identify the interference source of these terminals in the following way, as shown in Figure 4, comprise:
41:eNodeB identification pledge difference terminal;
42:eNodeB obtains time-domain information and the frequency domain information of matter difference terminal.
Wherein, time-domain information can refer to that (Time Slot, TS), frequency domain information can refer to the frequency that this calling takies to time slot.
As shown in Figure 5, eNodeB can recording cell in different time-gap and different carrier frequency corresponding parameters amounts etc., be that (Mobile Allocation Index Offset MAIO) is example to mobile allocation index offset with the frequency.For example, be (0,12) at two numerical value of time slot 6 and carrier frequency 1 correspondence, 0 expression MAIO wherein, 12 expression carrier/interface ratios (Carrier Interference Radio, CIR).
ENodeB can determine time slot and the frequency of terminal by ringing number.For example, determine time slot and carrier frequency is respectively 5 and 0 by ringing number, then because TS=5, carrier frequency (TRX)=0 correspondence (0,4), previous expression frequency can be determined the TS=5 of this terminal, frequency=0 so.
43:eNodeB searches for same frequency or the adjacent interference frequently of this matter difference terminal according to TS and frequency.
Wherein, co-channel interference refers to and all identical interference of the TS of this terminal, frequency, adjacent disturb frequently refer to identical with the TS of this terminal, the interference that frequency is adjacent.
For example, referring to Fig. 6, (0,20) corresponding terminal of the adjacent residential quarter in signal Figure 60 of base station record is exactly the co-channel interference of this matter difference terminal.
44:eNodeB chooses the interference source that interference strength is positioned at preceding X position, and wherein, X is the value of setting.
Wherein, eNodeB can be defined as confronting the interference strength of poor terminal with receiving above-mentioned co-channel interference or adjacent interference signals intensity frequently, sorts according to this this signal strength signal intensity, chooses a higher X interference source successively.
45:eNodeB reduces the transmitting power of the interference source of choosing.
Can reduce power control level thresholding and/or the quality threshold of interference source.
The time that the amplitude that reduces and reduction power continue can dispose.
Because power control is carried out according to thresholding, for example, when being higher than level threshold, the level value that carries in the measurement report shows that needs reduce power.Therefore, just can bigger possible reduction transmitting power after reducing thresholding, to reduce the interference that confrontation differs from terminal.
Perhaps, reducing transmitting power also can realize by the step-length that increases power control.
Wherein, the amplitude of increase also can dispose.Because the step-length that increases just can be so that transmitting power reduces more.
Present embodiment is example with eNodeB as executive agent, also can adopt miscellaneous equipment as executive agent in other systems, for example, substitutes above-mentioned eNodeB with BSC or BTS.
Present embodiment reduces the transmitting power of interference source by determining the interference source of matter difference terminal, can reduce the interference to these users, improves speech quality, avoids call drop or influences throughput.
