Embodiment one
According to the embodiment of the present invention, provide the acquisition methods of interference in a kind of frequency band, MR due to equipment manufacturer gathers with to gather implementation different, have in OMC(operation maintenance center) complete, what have completes on special MR acquisition server, so in preferred version, method of the present invention is applicable to being deployed on the equipment of MR collection and data processing.As shown in Figure 1, comprising:
Step 101, collects the measurement report (Measurement Report, MR) of cell-of-origin, and according to the quantity of MR and data statistics cell-of-origin and each adjacent cell each frequency MR quantity, cell-of-origin and each adjacent cell incoming level difference.
This cell-of-origin is the community of the interior interference of its frequency band of preanalysis determined in the present invention.The neighbor cell of this cell-of-origin is adjacent cell.
Mobile phone is under ACTIVE state, every 480ms uploads a MR, 1 Hibernian telephone traffic just can produce about 7500 MR, for a community, the MR of 1 hour even 1 day is magnanimity, and the level intensity of what these MR were detailed have recorded Serving cell and its adjacent area, interference level in the band that therefore data of these MR just can be used for judging that each frequency is subject to accurately in conjunction with the configuration information of frequency/community.
Specifically, in the communication process of user, system and mobile phone (MS) measure uplink downlink situation in real time, and form up-downgoing measurement report (MR).Mobile phone every 480ms under ACTIVE state uploads one-shot measurement report, and collect measurement report (MR) for each community, just define the MR statistics of magnanimity, the data format that we use is as follows:
1, the every frequency measurement report in community quantity (Num_MR)
The MR message number that each frequency in statistical unit time community receives.Is CI(cell ID as shown in following table one) statistics form in the=cell-of-origin of 57 (in the present embodiment, for ease of describing, thinking that cell-of-origin is that what to serve for MS is Serving cell) 1 hour measurement period:
| CellId | Carrier | Num_MR |
| 57 | 54 | 878 |
| 57 | 57 | 352 |
| 57 | 67 | 334 |
| 57 | 83 | 768 |
Table one Num_MR statistics form
2, cell receiver level and adjacent cell incoming level difference (SSDIF_SC_VS_NC)
Each adjacent cell received signal level difference that the cell receiver signal level recorded in the statistical unit time detects with it, and the level difference value counted on is added up according to different interval, determine the MR quantity in each interval range, namely add up the MR quantity (sampled point number) met in this by stages of level difference value according to statistical items (a certain interval range), add up one by one by adjacent cell.Statistical items is described as follows shown in table two:
The explanation of table two statistical items
Statistics according to the Serving cell after statistical items statistics and each adjacent cell is showed.With reference to following table three
Table Three S's SDIF_SC_VS_NC statistics form
Table three is depicted as in 1 hour measurement period, cell receiver level and adjacent cell incoming level difference, according to the data representation format after each statistical items statistics, wherein 35154 is Serving cell, the MR quantity in the base station identity code (BSIC) of its each adjacent area (NC), Broadcast Control Channel (BCCH) frequency used, CI and the interval representated by each statistical items is listed, for adjacent area 241 in table:
The MR quantity that adjacent area level is greater than Serving cell more than level 24dB (SSDIF_SC_VS_NC_0) is 0;
Adjacent area level is greater than Serving cell level 24dB(SSDIF_SC_VS_NC_1) MR quantity be 1;
Adjacent area level is greater than Serving cell level 2dB(SSDIF_SC_VS_NC_23) MR quantity be 17;
Adjacent area level is greater than Serving cell level 1dB(SSDIF_SC_VS_NC_24) MR quantity be 12;
Serving cell level is greater than adjacent area level 24dB(SSDIF_SC_VS_NC_49) MR quantity be 1;
The MR quantity that Serving cell level is greater than adjacent area more than level 24dB (SSDIF_SC_VS_NC_50) is 0.
By this statistics, MR quantity and the relative intensity of each adjacent cell that an endogenous cell detection of statistical time range arrives can be obtained, just can judge the correlation between cell-of-origin and each adjacent area thus, thus determine the annoyance level of adjacent area to cell-of-origin further.
Such as: as shown in following table four, be interference source community in the little zone of the preanalysis determined.For CI=468, community is totally 7 frequencies, i.e. TRX(s)=7, information is as table four, and annoyance level in the band that can be subject to according to each frequency of Statistic analysis, as the foundation that later frequency is optimized.
Table four
In like manner, the data format content as shown in Table 3 of the cell-of-origin adjacent cell each with it of CI=468 can also be counted according to statistical items as shown in Table 2.Concrete statistic processes is similar to the statistic processes of above-mentioned steps 101, no longer represents at this.
Step 103, the result according to statistics calculates frequency interference parameter in band;
Statistics is namely according to cell-of-origin and each adjacent cell each frequency MR quantity, cell-of-origin and each adjacent cell incoming level difference of the data statistics of report in the quantity of MR and MR.
Wherein, in band, frequency interference parameter comprises: each adjacent cell is to the co-channel interference sampled point quantity of cell-of-origin and adjacent frequency interference sample point quantity; Each adjacent cell respectively with the telephone traffic interference coefficient of cell-of-origin; The frequency quantity (the frequency quantity of cell-of-origin can be learnt from the MR report of this community or configuration information, is not repeated herein) of cell-of-origin and the frequency quantity of each adjacent cell; The frequency inventory (the frequency quantity of each adjacent cell and frequency inventory can be learnt or count the frequency quantity of each adjacent cell and concrete frequency from MR report from the configuration information of adjacent cell, are simply not repeated herein owing to obtaining method) of each adjacent cell
The above-mentioned result according to statistics calculates the step of frequency interference parameter in band by such as under type realization, comprising:
1, this each adjacent cell is calculated respectively to co-channel interference sampled point quantity Nco (n) of cell-of-origin and adjacent frequency interference sample point quantity Nadj (n) according to the MR quantity of each frequency in cell-of-origin of statistics, cell-of-origin incoming level difference with each adjacent cell incoming level difference.
Specifically, cell receiver level in the statistics of adjacent area and adjacent cell incoming level difference (SSDIF_SC_VS_NC) are that step-length is added up with 1dB, according to the sampled point quantity (statistical with reference in table two) of adjacent area in each level difference value interval, arrangement can be carried out to adjacent area sampled point to calculate, thus obtain the sampled point quantity that cell-of-origin may be interfered; Due to General Requirements co-channel interference protective ratio in GSM specification: the ratio of C/I(Serving cell and adjacent cell) >=9dB; adjacent frequency interference protection ratio: C/I >=-9dB; we just calculate for this standard, and interference protection ratio thresholding can adjust according to demand flexibly:
Adjacent area co-channel interference sampled point quantity Nco (n), in corresponding measurement report, cell-of-origin level is lower than the sampled point quantity of adjacent area level 8dB; With reference to formula one.
Nco (n)=SUM(SSDIF_SC_VS_NC_0, SSDIF_SC_VS_NC_1 ... SSDIF_SC_VS_NC_33) (one)
Adjacent area adjacent frequency interference sample point quantity Nadj (n), in corresponding measurement report, cell-of-origin level is lower than the sampled point quantity of adjacent area level-10dB; With reference to formula two.
Nadj (n)=SUM(SSDIF_SC_VS_NC_0, SSDIF_SC_VS_NC_1 ... SSDIF_SC_VS_NC_15) (two)
Still for CI=468, this community is cell-of-origin, according to same adjacent frequency interference protection ratio thresholding, in conjunction with for the statistics of this cell-of-origin according to such as table three, its adjacent area level intensity drops on sampled point quantity in interference fringe as table five, simultaneously according to configuration information, frequency quantity TRX (n) and the frequency inventory of each adjacent cell can be obtained, thus find out adjacent cell and whether cell-of-origin has TCH with adjacent frequency frequency;
Table five
2, according to the MR quantity of each frequency in cell-of-origin of statistics and the MR quantity of each frequency of each adjacent cell calculate each adjacent cell respectively with the telephone traffic interference coefficient of cell-of-origin.
Specifically, adjacent cell is to the TCH annoyance level of cell-of-origin and adjacent area telephone traffic size positive correlation, and adjacent area telephone traffic is large, just large with the probability of cell-of-origin frequency hit.Therefore can think that the telephone traffic of each community is equally distributed in a statistical time range, by MR sampled point quantity reflection telephone traffic, telephone traffic interference coefficient T (n) of each adjacent area and cell-of-origin can be calculated: with reference to formula three.
T (n)=min [sum(Num_MR (n))/sum(Num_MR (s)), 1] (three)
The MR message number that each frequency in certain adjacent area that wherein Num_MR (n) is cell-of-origin receives, the MR message number that Num_MR (s) receives for each frequency in cell-of-origin, if adjacent area telephone traffic is greater than cell-of-origin, then interference coefficient is 1.
With reference to interference coefficient T (n) that table six is each adjacent area of CI=468 community.
| Cell-of-origin CI | Num_MR(s) | Adjacent area CI | Num_MR(n) | T(n) |
| 468 | 11641 | 467 | 6879 | 0.59 |

Table six
Step 105, is disturbed index according in the band of each frequency in frequency interference parameter calculating cell-of-origin in band.
Specifically, this step can be divided into two kinds of modes according to type (TCH or the BCCH) difference of the frequency calculated.Be disturbed index according in the band of each frequency in frequency interference parameter calculating cell-of-origin in band, comprise:
When the frequency in cell-of-origin is TCH frequency, determine the adjacent cell of same frequent point and the adjacent cell of adjacent frequency frequency that there is this TCH frequency, and according to this interference sample point quantity with the adjacent cell again and again put, this telephone traffic interference coefficient with the adjacent cell of frequent point, this TCH frequency quantity of adjacent cell with frequent point and the TCH frequency quantity of cell-of-origin, and
According to the TCH frequency quantity of the interference sample point quantity of the adjacent cell of this adjacent frequency frequency, the telephone traffic interference coefficient of adjacent cell of this adjacent frequency frequency, the TCH frequency quantity of the adjacent cell of this adjacent frequency frequency and cell-of-origin, in the band calculating this TCH frequency in cell-of-origin, be disturbed index.
Adjacent area co-channel interference Nco (n) and adjacent area adjacent frequency interference Nadj (n) are cell-of-origins when having a traffic, and the adjacent area level detected is greater than the sampled point quantity of interference threshold;
1, TCH frequency interference calculation
Cell-of-origin is interference coefficient T (n) by the probability that adjacent area is disturbed;
Cell-of-origin and adjacent area intermediate-frequeney point quantity more, the collision probability of a certain frequency is lower, and the TCH frequency quantity of cell-of-origin is (TRX (s)-1), and the TCH frequency quantity of adjacent area is (TRX (n)-1);
What calculate each TCH frequency in cell-of-origin is disturbed index Z (f): with reference to formula four
Z (f)=∑ Nco (n) × T (n) × and [1/((TRX (s)-1) * (TRX (n)-1))]+∑ Nadj (n) × T (n) × and [1/((TRX (s)-1) * (TRX (n)-1))] (four)
Have 7 communities and cell-of-origin to have same adjacent frequency frequency in the adjacent area of CI=468, four can be disturbed index Z (f) with what calculate each frequency in cell-of-origin according to formula, for cell-of-origin TCH frequency 64, its every related data is as table seven:
Z(64)=1151×0.33×[1/((7-1)*(5-1))]+3×1×[1/((7-1)*(11-1))]=15.88
Table seven
What calculate each frequency in cell-of-origin respectively according to formula is disturbed index Z (f), and the results are shown in Table eight, being subject to the frequency that interior interference is the strongest is 64, is secondly 92.
| Z(64) | Z(92) | Z(48) | Z(12) | Z(78) | Z(89) |
| 15.88 | 14.09 | 8.65 | 7.77 | 0.24 | 0.19 |
Table eight
Because GSM network generally all can open frequency hopping, consider when therefore calculating Z (f) that the probability of interference of each frequency is the same, for the adjacent cell of not opening frequency hopping, (TRX (s/n)-1) this can replace with Num_MR (f)/Num_MR (s/n).
When the frequency in cell-of-origin is BCCH frequency, determine the adjacent cell of same frequent point and the adjacent cell of adjacent frequency frequency that there is this BCCH frequency, and according to this with the frequent interference sample point quantity of adjacent cell of point, the MR quantity of the adjacent cell of this adjacent frequency frequency, and
Index is disturbed according in the band of this BCCH frequency in the MR quantity calculating cell-of-origin of the interference sample point quantity of the adjacent cell of this adjacent frequency frequency, the adjacent cell of this adjacent frequency frequency.
2, BCCH frequency interference calculation
Because community BCCH frequency is normal transmitting, therefore the same adjacent frequency of BCCH will cause and continue interference, and its probability of interference can be estimated as, during adjacent cell being detected, with the interference sample point quantity of adjacent frequency frequency and the ratio of the total sampled point quantity of adjacent cell.
What calculate cell-of-origin BCCH frequency is disturbed index Z (f): with reference to formula five.
Z (f)=∑ [Nco (n)/sum(Num_MR (n))] and+∑ [Nadj (n)/sum(Num_MR (n))] (five)
Have 1 community and cell-of-origin to have BCCH adjacent frequency in the adjacent area of CI=468, what can calculate cell-of-origin BCCH frequency according to formula five is disturbed index Z (f), and its every related data is as table nine:
Z(26)=28/1087=0.026
| CellId_SC | CellId_NC | Nco(n) | Nadj(n) | Num_MR(n) | Mark with adjacent frequency frequency in adjacent area |
| 468 | 3216 | 272 | 28 | 1087 | 27 |
Table nine
In priority scheme, the present embodiment also can comprise the steps:
According to Annoyance Index in the band of each frequency in the cell-of-origin of above-mentioned calculating, interference level in the band judging each frequency.
In concrete judgement band, the method for interference level can with reference to prior art.As when Annoyance Index is greater than a certain threshold value in the band of TCH1 frequency, determine that TCH1 is subject to being with interior interference etc.
This programme proposes the method utilizing magnanimity measurement report data (MR data) to calculate interference in frequency band, the degree that each frequency in each community is subject to interior interference can be analyzed, for the analysis of quality problems in the network optimization, the optimization of network adjustment medium frequency provide reliable foundation.Because MR data volume is large, can extract real-time, therefore arithmetic result has reliability and promptness, and MR statistics is based on the measurement report technology of specification simultaneously, and each manufacturer data uniform format, therefore algorithm does not limit by producer, has general applicability.
