Embodiment one

According to embodiments of the present invention, there is provided the acquisition methods of interference in a kind of frequency band, because the MR of equipment manufacturer is adopted Collect and collect implementation difference, some is in OMC（Operation maintenance center）Complete, some is complete on special MR acquisition servers Into it is advantageous in scheme, method of the invention is adapted to be deployed in the equipment for completing MR collections and data processing.Such as Fig. 1 institutes Show, including：

Step 101, the measurement report of cell-of-origin is collected（Measurement Report, MR）, and according to MR quantity and Data statistics cell-of-origin and each frequency MR quantity of each adjacent cell, cell-of-origin receive level difference value with each adjacent cell.

The cell-of-origin is the cell of the interior interference of its frequency band of preanalysis determined in the present invention.The neighbor cell of the cell-of-origin For adjacent cell.

Mobile phone uploads a MR per 480ms under ACTIVE state, and 1 Hibernian telephone traffic can produces about 7500 MR, for a cell, the even MR of 1 day is magnanimity within 1 hour, and these MR it is detailed have recorded service The level intensity of cell and its adjacent area, therefore can be with for standard by the configuration information of these MR data combination frequency/cell The true interior interference level of band for judging that each frequency is subject to.

Specifically, in the communication process of user, system and mobile phone（MS）Measurement uplink downlink situation in real time, and shape Into up-downgoing measurement report（MR）.Mobile phone uploads one-shot measurement report under ACTIVE state per 480ms, for each cell pair Measurement report（MR）It is collected, is formed the MR statistics of magnanimity, the data format that we use is as follows：

1st, cell is per frequency measurement report quantity（Num_MR）

The MR message numbers that the statistical unit time each frequency of cell receives.As shown in following table one for CI（Cell mark Know）=57 cell-of-origin（In the present embodiment, for ease of description, it is believed that cell-of-origin be for MS service be serving cell）1 Statistics form in individual hour measurement period：

CellId	Carrier	Num_MR
			57	54	878
57	57	352
			57	67	334
57	83	768

The Num_MR statistics forms of table one

2nd, serving cell receives level and adjacent cell receives level difference value（SSDIF_SC_VS_NC）

Each adjacent cell that serving cell received signal level and its measured in the statistical unit time detects receives letter Number level difference value, and the level difference value counted on is counted according to different sections, it is determined that the MR in each interval range Quantity, i.e., according to statistical items（A certain interval range）Statistics meets the MR quantity in the level difference value by stages（Sampled point Number）, counted one by one by adjacent cell.Statistical items are described as follows shown in table two：

The statistical items explanation of table two

Serving cell after being counted according to statistical items and the statistical result of each adjacent cell are showed.With reference to following table three

The SSDIF_SC_VS_NC statistics forms of table three

Table three is shown in 1 hour measurement period, and serving cell receives level and receives level difference value with adjacent cell, according to Data representation format after each statistical items statistics, wherein 35154 be serving cell, lists the base of its each adjacent area (NC) in table The MR numbers in section used in station identification code (BSIC), BCCH (BCCH) representated by frequency, CI and each statistical items Amount, by taking adjacent area 241 as an example：

MR quantity of the adjacent area level more than more than serving cell level 24dB (SSDIF_SC_VS_NC_0) is 0；

MR quantity of the adjacent area level more than serving cell level 24dB (SSDIF_SC_VS_NC_1) is 1；

MR quantity of the adjacent area level more than serving cell level 2dB (SSDIF_SC_VS_NC_23) is 17；

Adjacent area level is more than serving cell level 1dB（SSDIF_SC_VS_NC_24）MR quantity be 12；

Serving cell level is more than adjacent area level 24dB（SSDIF_SC_VS_NC_49）MR quantity be 1；

Serving cell level is more than more than adjacent area level 24dB（SSDIF_SC_VS_NC_50）MR quantity be 0.

By this statistics, can obtain each adjacent cell that an endogenous cell detection of statistical time range arrives MR quantity and Relative intensity, thus it may determine that correlation between cell-of-origin and each adjacent area, so as to further determine that adjacent area is small to source The annoyance level in area.

Such as：As shown in following table four, to disturb cell-of-origin in the small zone of preanalysis of determination.By taking CI=468 as an example, cell Totally 7 frequencies, i.e. TRX（s）=7, information such as table four, can according to the interior annoyance level of band that each frequency of Statistic analysis is subject to, as with The foundation of frequency optimization afterwards.

Table four

Similarly, can also be counted according to statistical items as shown in Table 2 the cell-of-origins of CI=468 and its each adjacent cell as Data format content shown in table three.Specific statistic processes is similar to the statistic processes of above-mentioned steps 101, no longer represents herein.

Step 103, calculated according to the result of statistics with interior frequency interference parameter；

Statistical result is cell-of-origin and each frequency of each adjacent cell for the data statistics reported in quantity and MR according to MR MR quantity, cell-of-origin and each adjacent cell receive level difference value.

Wherein, include with interior frequency interference parameter：Co-channel interference sampled point quantity and adjacent frequency of each adjacent cell to cell-of-origin Interference sample point quantity；Each adjacent cell telephone traffic interference coefficient with cell-of-origin respectively；The frequency quantity of cell-of-origin（Cell-of-origin Frequency quantity can be learnt from the MR of cell report or configuration information, will not be described here）With the frequency quantity of each adjacent cell； The frequency inventory of each adjacent cell（The frequency quantity and frequency inventory of each adjacent cell can be learnt from the configuration information of adjacent cell Or the frequency quantity of each adjacent cell and specific frequency are counted from MR reports, do not gone to live in the household of one's in-laws on getting married herein simply due to obtaining method State）

It is above-mentioned to be realized in the following way with the step of interior frequency interference parameter according to the calculating of the result of statistics, including：

1st, level difference value is received according to the MR quantity of each frequency in cell-of-origin of statistics, cell-of-origin and receives electricity with each adjacent cell Adjusted value calculates each adjacent cell and the co-channel interference sampled point quantity Nco (n) and adjacent frequency interference sample of cell-of-origin is counted respectively Measure Nadj (n).

Specifically, the serving cell in the statistics of adjacent area receives level and receives level difference value with adjacent cell（SSDIF_SC_ VS_NC）It is to be counted by step-length of 1dB, according to sampled point quantity of the adjacent area in each level difference value section（With reference in table two Statistical）, arrangement calculating can be carried out to adjacent area sampled point, so as to obtain the sampling number that cell-of-origin may be interfered Amount；Due to typically requiring that co-channel interference protects ratio in GSM specifications：C/I（The ratio between serving cell and adjacent cell）>=9dB, adjacent frequency are done Disturb protection ratio：C/I >=-9dB, we are just calculated by taking this standard as an example, and interference protection ratio thresholding can be clever according to demand Adjustment living：

Adjacent area co-channel interference sampled point quantity Nco (n), correspond to cell-of-origin level in measurement report and be less than adjacent area level 8dB Sampled point quantity；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 less than adjacent area level- 10dB sampled point quantity；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 by taking CI=468 as an example, this cell is cell-of-origin, according to same adjacent frequency interference protection ratio thresholding, with reference to small for the source According to the statistical result of such as table three, its adjacent area level intensity falls the sampled point quantity such as table five, while basis in interference fringe in area Configuration information, the frequency quantity TRX (n) and frequency inventory of each adjacent cell can be obtained, so as to find out adjacent cell and cell-of-origin Whether TCH is had with adjacent frequency frequency；

Table five

2nd, each neighbour is calculated 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 The cell telephone traffic interference coefficient with cell-of-origin respectively.

Specifically, TCH annoyance level and adjacent area telephone traffic size positive correlation of the adjacent cell to cell-of-origin, adjacent area telephone traffic Greatly, the probability with cell-of-origin frequency hit is with regard to big.It can thus be assumed that the telephone traffic of each cell is equal in a statistical time range Even distribution, reflect telephone traffic with MR sampled points quantity, the telephone traffic interference coefficient T of each adjacent area and cell-of-origin can be calculated (n)：With reference to formula three.

T(n)=min[sum（Num_MR(n)）/sum（Num_MR(s)）,1] （Three）

Wherein Num_MR (n) is the MR message numbers that each frequency in certain adjacent area of cell-of-origin receives, and Num_MR (s) is that source is small The MR message numbers that each frequency in area receives, if adjacent area telephone traffic is more than cell-of-origin, interference coefficient 1.

With reference to the interference coefficient T (n) for each adjacent area that table six is the cell of CI=468.

Cell-of-origin CI	Num_MR(s)	Adjacent area CI	Num_MR(n)	T(n)
					468	11641	467	6879	0.59
468	11641	775	4128	0.35

Table six

Step 105, according to interior frequency interference parameter calculate cell-of-origin in each frequency band in be disturbed index.

Specifically, the step can be divided into two ways according to type (the TCH or BCCH) difference of the frequency of calculating.Root Index is disturbed in the band of each frequency according to being calculated with interior frequency interference parameter in cell-of-origin, including：

When the frequency in cell-of-origin is TCH frequencies, it is determined that the same adjacent cell and adjacent frequency put again and again in the presence of the TCH frequencies The adjacent cell of frequency, and according to the interference sample point quantity of the same adjacent cell put again and again, the same adjacent cell put again and again Business amount interference coefficient, the same TCH frequencies quantity of adjacent cell and the TCH frequency quantity of cell-of-origin put again and again, and

Disturbed according to the interference sample of the adjacent cell of adjacent frequency frequency point quantity, the telephone traffic of the adjacent cell of the adjacent frequency frequency The TCH frequencies quantity of adjacent cell and the TCH frequency quantity of cell-of-origin of coefficient, the adjacent frequency frequency, calculate the TCH in cell-of-origin Index is disturbed in the band of frequency.

Adjacent area co-channel interference Nco (n) and adjacent area adjacent frequency interference Nadj (n) is in the case that there is traffic cell-of-origin, to detect Adjacent area level be more than interference threshold sampled point quantity；

1st, TCH frequencies interference calculation

The probability that cell-of-origin is disturbed by adjacent area is interference coefficient T (n)；

Cell-of-origin and adjacent area intermediate-frequeney point quantity are more, and the collision probability of a certain frequency is lower, the TCH frequency numbers of cell-of-origin Measure as (TRX (s) -1), the TCH frequencies quantity of adjacent area is (TRX (n) -1)；

Calculate each TCH frequencies in cell-of-origin is disturbed index Z (f)：With reference to formula four

Z (f)=∑ { Nco (n) × T (n) × [1/ ((TRX (s) -1) * (TRX (n) -1))] }+∑ { Nadj (n) × T (n) × [1/ ((TRX (s) -1) * (TRX (n) -1))] } (four)

There are 7 cells and cell-of-origin to have same adjacent frequency frequency in CI=468 adjacent area, cell-of-origin can be calculated according to formula four Each frequency is disturbed index Z (f), by taking cell-of-origin TCH frequencies 64 as an example, its every related data such as table seven：

Z (64)=1151 × 0.33 × [1/ ((7-1) * (5-1))]+3 × 1 × [1/ ((7-1) * (11-1))]=15.88

Table seven

Calculate each frequency in cell-of-origin respectively according to formula is disturbed index Z (f), the results are shown in Table eight, by with interior dry It is 64 to disturb most strong frequency, 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

The probability of interference that each frequency is considered because GSM network typically can all open frequency hopping, therefore when calculating Z (f) is one Sample, the adjacent cell for being not turned on frequency hopping, (TRX (s/n) -1) this could alternatively be Num_MR (f)/Num_MR (s/ n)。

When the frequency in cell-of-origin is BCCH frequencies, it is determined that in the presence of the same adjacent cell put again and again of the BCCH frequencies and neighbour Again and again the adjacent cell put, and according to this with the interference sample point quantity of the adjacent cell put again and again, the adjacent cell of the adjacent frequency frequency MR quantity, and

Calculated according to the interference sample of the adjacent cell of adjacent frequency frequency point quantity, the MR quantity of the adjacent cell of the adjacent frequency frequency Index is disturbed in the band of the BCCH frequencies in cell-of-origin.

2nd, BCCH frequencies interference calculation

Because cell BCCH frequencies are often to launch, therefore BCCH same adjacent frequency will cause to continue interference, and its probability of interference can It is estimated as, during detecting adjacent cell, with interference sample point quantity and the total sampled point ratio of number of adjacent cell of adjacent frequency frequency.

Calculate cell-of-origin BCCH frequencies is disturbed index Z (f)：With reference to formula five.

Z(f)=∑[Nco(n)/sum（Num_MR(n)）]+∑[Nadj(n)/sum（Num_MR(n)）] （Five）

There are 1 cell and cell-of-origin to have BCCH adjacent frequency in the adjacent area of CI=468, cell-of-origin can be calculated according to formula five BCCH frequencies are disturbed index Z (f), its every related data such as table nine：

Z(26)=28/1087=0.026

CellId_SC	CellId_NC	Nco(n)	Nadj(n)	Num_MR(n)	Marked in adjacent area with adjacent frequency frequency
						468	3216	272	28	1087	27

Table nine

In priority scheme, the present embodiment may also include the steps of：

According to the interior Annoyance Index of band of each frequency in the cell-of-origin of above-mentioned calculating, the interior interference water of band of each frequency is judged It is flat.

Specifically judge that the method with interior interference level is referred to prior art.Such as when the interior Annoyance Index of the band of TCH1 frequencies During more than a certain threshold value, determine TCH1 by with interior interference etc..

This programme, which proposes, utilizes magnanimity measurement report data（MR data）, can be with to calculate the method for interference in frequency band The each frequency of each cell is analyzed by the degree with interior interference, is the analysis of quality problems in the network optimization, in network adjustment The optimization of frequency provides reliable foundation.Because MR data volumes are big, can extract real-time, therefore arithmetic result have reliability and Promptness, while measurement report technology of the MR statistics based on specification, each manufacturer data uniform format, therefore algorithm is not limited by producer System, has general applicability.
