Referred to as PCI is interfered) performance that can all seriously affect LTE system, reduce Signal to Interference plus Noise Ratio (the Signal to of terminal
Interference plus Noise Ratio, abbreviation SINR) measured value, the rate of terminal uplink/downlink is reduced, and cause to use
The problems such as family access failure rate is high and drop rate is high.
In the prior art, whether the region of high interference region or quality of service difference is verified by 3/ mould of PCI moulds, 6/ mould 30
When more than two cells of conflict provide covering, road survey mainly is carried out to verifying region by drive test means, and
Judge whether detected region is the covering provided by least two cells that PCI conflicts according to measurement result.
But the prior art is often quality of service go wrong after, staff can just carry out problematic region
Drive test, the interference for belonging to passive are verified, and real-time is bad.And every time drive test be required for consuming a large amount of manpower and materials it is timely

Difference more than the signal strength information of the signal strength information and serving cell of the second predetermined threshold or the first adjacent cell exists
In first preset range or the signal strength information of the first adjacent cell and the difference of first community are in the second preset range
MR, as the first adjacent cell for the 30 interference sample point of PCI moulds of serving cell.
303c2, interference verification function module are dry to the PCI moulds 30 of serving cell by all first adjacent cells got
It disturbs sampled point to add up, obtains the first adjacent cell and total sampling number is interfered to the PCI moulds 30 of serving cell.
Wherein, above-mentioned first community is the maximum cell of signal strength information in each MR, the first above-mentioned adjacent cell
For any adjacent cell in the MR sampled points of the same serving cell, other adjacent cells are to 3 interference sample of serving cell PCI moulds
Point can also obtain according to the method described above.
Illustratively, since the network construction of current LTE generally uses the basic cooperation of 2 antenna of base station side, and PCI moulds
3 influences of the interference for system are bigger, therefore, below will be with so the interference of PCI moulds 3 is the emphasis direction that LTE system is verified
PCI moulds 3 interfere specifically to discuss scheme provided by the present invention.
Based on step 303a it is found that judge whether an adjacent cell generates strong mould 3 to the PCI of serving cell dry
It disturbs, needs to be carried out at the same time both sides verification：
In a first aspect, there is the conflict of mould 3 in the PCI of adjacent cell and serving cell, for example, if in a MR
Cell A is as serving cell, and another is also appeared in there are the adjacent cell B that mould 3 conflicts in the MR with cell A, then judgement should
There are the conflicts of mould 3 by PCIs of the adjacent cell B to cell A.And above-mentioned there are the conflict of mould 3 is exactly cell A and adjacent cell B difference needles
It is equal that remainder after modular arithmetic is carried out to integer 3.
The signal strength of second aspect, adjacent cell is bigger, specifically, here for the bigger accounting side of signal strength
There are three types of methods, the first is one the second predetermined threshold value of setting, if the signal strength information of adjacent cell B is more than the second default threshold
When value, then judge that the signal strength of adjacent cell B is bigger；Second is by the signal strength information and same of adjacent cell B
The strongest cell of signal strength information in MR is compared, if in the signal strength information of adjacent cell B and same MR
When the difference of the strongest cell of signal strength information is in the second preset range, then judge that the signal strength of adjacent cell B compares
Greatly；The third by the signal strength information of adjacent cell B compared with the signal strength information of serving cell A, if the signal of adjacent cell B
When the difference of the signal strength information of strength information and serving cell A is in the first preset range, then the letter of adjacent cell B is judged
Number intensity is bigger.
If the adjacent cell B in this MR meets above-mentioned both sides and verifies condition, adjacent cell B is small for servicing
The 3 interference sample point of PCI moulds of area A is increased by a counting, i.e. the MR is as adjacent cell B for a PCI mould of serving cell A
3 interference sample points, and above-mentioned two condition only meets one or is all unsatisfactory for, counting does not increase.For example, remembering in a MR
In record, the PCI=2 of serving cell A, and the PCI=38 of adjacent cell B；Meanwhile the RSRP of adjacent cell B and most strong cell RSRP
Difference is less than or equal to 6dB, then adjacent cell B is increased by a counting for the 3 interference sample point of PCI moulds of serving cell A.With
Afterwards, can be directed to all cell A as serving cell simultaneously cell B as adjacent cell MR traverse count after, just obtain
Adjacent cell B interferes total sampling number for the PCI moulds 3 of serving cell A.
Certainly, if to judge whether an adjacent cell generates the strong interference of mould 6 or mould 30 to the PCI of serving cell
When interference is verified, it is available with the scheme that the present invention is interfered for PCI moulds 3 and is calculated, only cell PCI is carried out
Be to be directed to integer 6 or integer 30 respectively to carry out modular arithmetic, acquire remainder, which is not described herein again.
304, interference verifies function module and each adjacent cell is interfered total sampling number and clothes to the PCI of serving cell respectively
The total sampling numbers of MR of business cell make ratio, obtain PCI interference sample point accounting of each adjacent cell to serving cell, to respectively
According to each adjacent cell to the PCI interference sample point accountings of serving cell judge whether to corresponding adjacent cell and serving cell into
Row PCI interference corrections.
Specifically, interference verifies function module in the total sampling number of PCI interference for obtaining a certain adjacent cell to serving cell
Afterwards, PCI interference sample point accounting of the adjacent cell to serving cell can be calculated, computational methods are using the adjacent cell for clothes
The PCI of business cell interferes the total sampling numbers of the MR of total sampling number divided by the serving cell, obtains the adjacent cell to serving cell
PCI interference sample point accountings, and then determine whether are the adjacent cell and the serving cell according to the PCI interference samples point accounting
There are serious PCI interference.It interferes simultaneously and verifies function module when carrying out different PCI interference verifications, the judgement of selection
Benchmark is also different.And for adjacent cell to the severity of the PCI interference of serving cell, general PCI interferes total sampled point
The the more or PCI interference sample point accountings of number the high more serious, just needs to carry out the PCI of the cell pair of PCI serious interferences
Adjustment, or antenna feeder is optimized, such as adjust azimuth, the angle of declination etc. of serving cell and adjacent cell.As follows.
Optionally, when LTE system verifies carrying out interference the cell interfered there are PCI moulds 3, it is based on step 303a1

The total sampling numbers of MR of serving cell make ratio, obtain PCI mould 3 interference sample point accounting of first adjacent cell to serving cell.
If 304a2, the first adjacent cell are more than third predetermined threshold to the 3 interference sample point accounting of PCI moulds of serving cell,
Interference verifies function module and judges that first adjacent cell needs to carry out 3 interference correction of PCI moulds with serving cell.
Optionally, when LTE system verifies carrying out interference the cell interfered there are PCI moulds 6, it is based on step 303b1
With step 303b2, by taking the first adjacent cell as an example, step 304 specifically comprises the following steps：
304b1, interference verify function module by the first adjacent cell to the PCI moulds 6 of serving cell interfere total sampling number with
The total sampling numbers of serving cell MR make ratio, obtain PCI mould 6 interference sample point accounting of first adjacent cell to serving cell.
If 304b2, the first adjacent cell are more than the 5th predetermined threshold to the 6 interference sample point accounting of PCI moulds of serving cell,
Interference verifies function module and judges that first adjacent cell needs to carry out 6 interference correction of PCI moulds with serving cell.
Optionally, when LTE system verifies carrying out interference the cell interfered there are PCI moulds 30, it is based on step 303c1
With step 303c2, by taking the first adjacent cell as an example, step 304 specifically comprises the following steps：
304c1, interference verify function module by the first adjacent cell to the PCI moulds 30 of serving cell interfere total sampling number with
The total sampling numbers of serving cell MR make ratio, obtain PCI mould 30 interference sample point accounting of first adjacent cell to serving cell.
If 304c2, the first adjacent cell are more than the 6th predetermined threshold to the 30 interference sample point accounting of PCI moulds of serving cell,
Verification function module is then interfered to judge that first adjacent cell needs to carry out 30 interference correction of PCI moulds with serving cell.
Illustratively, step 304 is specifically discussed with the interference of PCI moulds 3 here, based on step 304a1 and 304a it is found that working as
Interference verifies function module after getting adjacent cell B and interfering total sampling number for the PCI moulds 3 of serving cell A, can calculate
For adjacent cell B for the 3 interference sample point accounting of PCI moulds of serving cell A, computational methods are adjacent cell B for serving cell A
PCI moulds 3 interfere total sampling number divided by effective total sampling number of adjacent cell A.Because PCI moulds 3 interfere in the lte networks not
It can avoid completely, so total sampling number can only be interfered more with PCI moulds 3 or 3 interference sample point accounting of PCI moulds weighs neighbour
The severity that cell B interferes the PCI moulds 3 of serving cell A, general PCI moulds 3 interfere total sampling number more or PCI
The 3 interference sample point accounting of mould the high more serious, and for the cell pair of 3 serious interference of PCI moulds, it just needs to the two cells
PCI be adjusted, or antenna feeder is optimized, for example, adjustment serving cell A and adjacent cell B azimuth, angle of declination etc..
In addition, according to the above process, function module is verified in interference can be between LTE in flakes all cells of overlay area
Carry out the verification that 3/ mould of PCI moulds, 6/ mould 30 interferes.Can be that network maintenance staff exports packet again by the user interface in Fig. 1
Statistics list containing all cells pair to conflict there are PCI, or alerting service is directly provided, such as according between cell pair
The descending Sequential output of 3/ mould of PCI moulds, 6/ mould, 30 interference sample point accounting, interfered according to PCI convenient for technical staff tight
Weight degree, come to cell to being adjusted.
