The specific aspect that will specifically introduce each judgment rule below.
1. adjacent area judgment rule
Judgment rule：Exceptional signaling flow it is interior for the previous period there are A3 or A5 events and involved cell not with master
In the case of the relationship of serving cell configuring adjacent cell, the final root is determined because of adjacent area leakage.There is no the situations of adjacent area leakage
Under, if adjacent area frequency point, physical-layer cell identifier PCI, the frequency point of tracking area code TAC and adjacent area cell-level parameter configuration, PCI,
TAC is inconsistent, it is determined that neighboring BS information configuration error.
As an example, check and whether have MRE data in the preceding 10s of exceptional signaling flow (MRE and XDR interrelational forms, under
Together：MRE.objectid=XDR.CellID AND MRE.MmeUeS1apId=XDR.MMEUES1APID AND
MRE.MmeGroupId=XDR.MMEGroupID), if there is A3 or A5 events, judge one by one the cell reported whether with main clothes
Cell of being engaged in configuring adjacent cell relationship, is judged as adjacent area leakage if not.
Nearest 2 MRO (Mobility Robustness in 20s before acquisition single user exceptional signaling flow
Optimization, mobile robustness optimization) data, check MRO adjacent areas to whether meeting switching condition and (working as Serving one by one
RSRP (main serving cell Reference Signal Received Power)<A5 alien frequencies this cell decision thresholds, Neighbor RSRP (join by adjacent cell
Examine signal reception power)>During A5 alien frequencies Target cell decision thresholds, cell involved by judgement whether with main serving cell configuring adjacent cell
Relationship), in the condition that meets and configuring adjacent cell relationship, adjacent area frequency point be configured, PCI (physical-layer cells are checked at this time
Mark), frequency point, PCI, TAC of TAC (Tracking Area Code, track area code) and adjacent area cell-level parameter configuration be
It is no consistent, neighboring BS information configuration error is determined if inconsistent.
2. breakdown judge is regular
Judgment rule：Judge whether warning code, in the presence of having warning code, determine final root because
Corresponding failure problem.
Specifically, when there are warning code (Huawei 29204/26223, in emerging 198094831, Nokia 76576304/
76576203/76576303) in the case of, X2 link failures are determined.
When there are warning code (Huawei 29201/26223, in emerging 198094830, Nokia 76566202/76576202/
76576204) in the case of, S1 link failures are determined.
Clock problem warning code (Huawei 26262/26260, Nokia 76504160/76520026/ when it is present
76514122/76524011/76524122/76524123/76524124/76524125th, in it is emerging 198092217) or veneer is hard
Part fault warning code (Huawei 26200, in emerging 198097060, Nokia 76502017/76521815/76522016/
76531811/76531815/76532016) in the case of, cell failure is determined.
3. Covering judgment is regular
Judgment rule：First adjacent area decision rule, breakdown judge rule come be confirmed whether there are problems that adjacent area, alarm ask
Topic, if be judged as in the presence of if it is false it is weak covering (adjacent area, alarm)；It, can also be by judging MRO in the case of false weak covering
Whether level value is less than weak coverage threshold value to determine whether being the true weak covering of property.
False weak covering：
(1) in the interior for the previous period there are A3 or A5 events and involved cell is (for example, cell-of-origin of exceptional signaling flow
Or Target cell) not with main serving cell configuring adjacent cell relationship in the case of, determine adjacent area leakage.
As an example, check and whether have MRE data in the preceding 10s of exceptional signaling flow (MRE and XDR interrelational forms, under
Together：MRE.objectid=XDR.CellID AND MRE.MmeUeS1apId=XDR.MMEUES1APID AND
MRE.MmeGroupId=XDR.MMEGroupID), if there is A3 or A5 events, judge one by one the cell reported whether with main clothes
Cell of being engaged in configuring adjacent cell relationship, is judged as adjacent area leakage if not.
(2) it is received in the reference signal of the Reference Signal Received Power of the co-frequency neighbor cell of involved cell and main serving cell
The difference of power be more than predetermined threshold and involved cell not with main serving cell configuring adjacent cell relationship in the case of, determine that adjacent area is leaked
Match.
As an example, obtaining before single user, (Mobility Robust Optimization are moved nearest 2 MRO in 20s
Dynamic robustness optimization) data, MRO homogeneous-frequency adjacent-domains level is calculated successively, as Neighbor RSRP-Serving RSRP>Off+
During Ofs+Hys, judge the cell reported whether with main serving cell configuring adjacent cell relationship, be judged as if not adjacent area leak
Match.
Wherein (with reference to 3GPP 36.331)：
Neighbor RSRP：The Reference Signal Received Power of adjacent cell；
Serving RSRP：Main serving cell Reference Signal Received Power；
Off：The offset parameter of A3 events；
Ofs：The specific frequency biasing of serving cell；
Hys：Lag parameter；
(3) it is less than A5 alien frequencies this cell decision thresholds in the Reference Signal Received Power of main serving cell, involved cell
The Reference Signal Received Power of adjacent cell is with being more than A5 alien frequencies Target cell decision thresholds, and involved cell and main serving cell are not
In the case of the relationship of configuring adjacent cell, adjacent area leakage is determined.
As an example, nearest 2 MRO data in 20s before obtaining single user, obtain one by one involved by cell to adjacent cell frequency point
The different-frequency measure parameter (A5 this cell of alien frequencies decision threshold, A5 alien frequencies Target cells decision threshold) of setting, works as Serving
RSRP (Reference Signal Received Power of main serving cell)<A5 alien frequencies this cell decision threshold values, Neighbor RSRP are (adjacent small
The Reference Signal Received Power in area)>During A5 alien frequencies Target cell decision threshold values, judge whether the cell reported is small with main service
Area configuring adjacent cell relationship, is judged as adjacent area leakage if not.
(4) in the adjacent cell of involved cell there are hardware fault website, and any one MRO data point distance fault website
Maximum distance be less than predetermined distance threshold in the case of, determine false covering.
As an example, MRO data in 10s before and after obtaining single user exceptional signaling flow, confirm in neighboring cell list exist it is hard
Part failure website calculates any one MRO data point distance fault website maximum distance<In 200m, then it is judged as false covering.
The weak covering of true property：
As described above, in the case of false weak covering, can also whether weak coverage threshold be less than by decision level value
Value is to determine whether be the true weak covering of property.
4. interfere judgment rule
Judgment rule：According to routing information protocol (RIP) parameter of cell involved in predetermined period with predetermined threshold
The tendency of comparison and Physical Resource Block (PRB) parameter at least one determine final root because of (and interference type).If tentatively sentence
It is positioned as external disturbance, then judges whether one or more area interferences of radius 1km meet external disturbance.
Interference type includes：Interference at crossed slot, GSM (Global System for Mobile Communication,
Global system for mobile communications) Intermodulation Interference, PHS ((Personal Handy-phone System, personal handhold phone system
System) Personal Handyphone System interference, telecommunications FDD (Frequency Division Duplexing, frequency division duplex) _ unicom TDD (Time
Division Duplexing, time division duplex) it is _ unicom TDD clutter interferences, telecommunications TDD clutter interferences, the interference of equipment obstruction, dry
Disturb device interference, equipment interference.
Interference at crossed slot：The average RIP of multiple sub-frame of uplink in the predetermined period be more than first threshold and
In the case that the average RIP of second sub-frame of uplink is less than second threshold, determine that sub-frame configuration, vertical shift, no alarm GPS problems are drawn
The interference at crossed slot risen, wherein, the first threshold is more than the second threshold.
As an example, the statistics of one period of cell, if multiple sub-frame of uplink (each subframe corresponds to 100 PRB)
Average RIP>The average RIP of -90 and the 2nd subframes<- 105, then the cell is sub-frame configuration, vertical shift, no alarm GPS problems
Caused interference at crossed slot；
GSM Intermodulation Interferences：Third threshold value, and the two are both greater than in the RIP of PRB of arbitrary two subframes in same position
The difference of the RIP of the average RIP and adjacent PRB of PRB are more than predetermined difference value threshold value, it is determined that GSM Intermodulation Interferences, wherein, described the
Three threshold values are more than the first threshold.
As an example, the statistics of one period of cell, if arbitrary 2 PRB (position is identical in all subframes, for example,
The PRB 0 of the second subframe and PRB 0 of third subframe) RIP simultaneously>- 80dBm, and the mean value RIP- of two PRB is adjacent
The RIP of PRB (for example, PRB 1 of the second subframe and PRB 1 of third subframe)>10dB is then judged as GSM Intermodulation Interferences；
PHS Personal Handyphone Systems interfere：RIP in the predetermined PRB of F1 frequency ranges or in F2 frequency ranges there are fixed three PRB is big
In third threshold value, and the difference of the RIP of the average RIP and adjacent PRB of these three PRB is more than the difference threshold, it is determined that PHS is small
Well-informed interference.
As an example, the statistics of one period of cell, if F1 frequency ranges (frequency point 38350) PRB (76~99) or
Occurring arbitrary three subframes in F2 frequency ranges (frequency point 38404), (position is identical in all subframes, for example, sub in the PRB of same position
The PRB 0 of the frame 2 and PRB0 of the subframe 3 and PRB 0 of subframe 4) RIP simultaneously>- 80dBm, and the F1 frequency ranges, F2 frequency ranges
The RIP of the adjacent PRB of mean value RIP- of these three PRB is (for example, the PRB 1 of the subframe 2 and PRB 1 of the subframe 3 and PRB of subframe 4
1)>10dB is then judged as that PHS Personal Handyphone Systems interfere；
Telecommunications FDD_ unicom TDD_ unicom TDD clutter interferences：For arbitrary subframe, the PRB for having started predetermined quantity according to
The average RIP values of secondary every five PRB are more than or equal to the average RIP values of subsequent five PRB, and the average RIP of five PRB of section start
The difference of the average RIP values of five PRB is more than the predetermined difference value threshold value at value and end, then is F1/E1/D1's in involved cell
In the case of, determine corresponding telecommunications FDD/ unicom TDD/ unicom TDD clutter interferences
As an example, the statistics of one period of cell, if arbitrary subframe, the average RIP values of PRB (0~4)>=PRB
The average RIP values of (5~9)>=...>The average RIP values of=PRB (35~39) and the average RIP values-PRB of PRB (0~4)
The average RIP values of (35~39)>10db, and if the cell be F1/E1/D1, the cell be telecommunications FDD/ unicom TDD/ unicom
TDD clutter interferences：
Telecommunications TDD clutter interferences：For arbitrary subframe, the PRB of predetermined quantity is played at end, and every five PRB are averaged successively
RIP values are more than or equal to the average RIP values of subsequent five PRB, and the average RIP values of five PRB of section start and five PRB at end
The differences of average RIP values be more than the predetermined difference value threshold value, then in involved cell in the case of E3/D3, to determine corresponding telecommunications
TDD clutter interferences.
As an example, the statistics of one period of cell, if for arbitrary subframe, the average RIP values of PRB (99~95)>
The average RIP values of=PRB (94~90)>=...>The average RIP values of=PRB (94~90) and being averaged for PRB (99~95)
The average RIP values of RIP values-PRB (64~60)>10db, and if the cell is E3/D3, the cell is all spuious dry for telecommunications TDD
It disturbs；
Equipment obstruction interference：It is more than the situation of second threshold in the average RIP only there are one all sub-frame of uplink of cell
Under, it is determined that equipment obstruction interference.
As an example, the statistics of one period of cell, if only there are one the average RIP of all sub-frame of uplink of cell>-
105, then the cell is equipment obstruction interference；
Interference unit interferes：The average resource block RB interference values of cell in involved cell and preset distance are more than described the
In the case that two threshold values or predetermined RB interference values are more than the 4th threshold value, it is determined that interference unit interferes, wherein, the 4th threshold value is small
In the first threshold but more than the second threshold.
As an example, the statistics of one period of cell, if the cell (one or more cells of periphery radius 1KM ranges)
RB interferes mean value>- 105dBm or the last 10 RB interference values>- 100dBm, then the cell is interference unit interference；
Equipment is interfered：Be both greater than the first threshold in the RIP of PRB of arbitrary two subframes in same position, and this two
The difference of the RIP of the average RIP and adjacent PRB of a PRB are more than the difference threshold, and there are 3 times or more by all PRB in the cell
Such case, it is determined that equipment is interfered.
As an example, the statistics of one period of cell, if any two subframe is in PRB (all subframes of same position
Upper position is identical, for example, the PRB 0 of the subframe 2 and PRB 0 of subframe 3) RIP simultaneously>- 90dBm, and the mean value of two PRB
The RIP of the adjacent PRB of RIP- (for example, PRB 1 of the subframe 2 and PRB 1 of subframe 3)>10dB, and go out in 100 PRB in the cell
Existing the above situation 3 times or more, then be judged as that equipment is interfered；
Other interference：It is more than the first threshold, and Reference Signal Received Quality in Reference Signal Received Power RSRP
RSRQ is less than quality threshold or RIP is more than the second threshold or uplink signal interference-to-noise ratio UL SINR are less than accordingly
Predetermined threshold, it is determined that radio network problems are caused by interfering, and when the frequency of failure caused by the interference account for involved cell this when
The ratio of the total frequency of failure of section is more than estimated rate threshold value, and in the case of any one of other above-mentioned interference, it is determined that its
He interferes.
As an example, the statistics of one period of cell, in the case of there is no other above-mentioned interference, RSRP in MRO
(Reference Signal Receiving Power, Reference Signal Received Power)>- 110dBm and RSRQ (Reference
Signal Receiving Quality, Reference Signal Received Quality)<The average RIP values of -12.5 or 100 PRB>-105
Or UL SINR (Signal to Interference plus Noise Ratio, Signal Interference and Noise Ratio)<- 3 nothings
Line network problem causes for interference, and the frequency of failure caused by interference accounts for the cell period total frequency of failure>40%, and it is non-with
On interference then the cell be other interference.
5. human factor judgment rule
Judgment rule：Exist in the predetermined amount of time before and after time of failure and deactivate user, physical-layer cell mark
In the case of knowing at least one of (PCI) modification and the modification of interrupting service parameter, human factor is determined.
As an example, Main Basiss producer webmaster operation sheet, before and after the time occurred in event in 5min, sentences one by one
It is disconnected with the presence or absence of deactivating the operations such as user or modification PCI or modification interrupting service parameter, if judging human factor in the presence of if.
6. other factors judgment rule
Judgment rule：Cell-level with frequency handoff parameter not within the predefined range in the case of, determine corresponding handoff parameter
It sets unreasonable.
As an example, cell-level is verified with frequency handoff parameter A3offset+Hysteresis (the specific frequencies of this cell of A3 events
Dot frequency deviation+A3 events lag parameter) not equal to [2dB, 4dB] section, A3Time-to-trigger (A3 triggered times) is no
Equal to [320ms, 1280ms], then judge that corresponding handoff parameter setting is unreasonable.
7. redirect judgment rule
Judgment rule：Under the Reference Signal Received Power of main serving cell thresholding threshold is redirected in the different system of A2 alien frequencies
Value, and the different system of A2 alien frequencies redirects threshold value and is higher than pre-determined threshold threshold value, it is determined that the blind redirection thresholding settings of A2 are excessively high.
As an example, measurement pathological system before abnormal release signaling is blind to redirect Serving RSRP in A2 reports
Whether (Reference Signal Received Power of main serving cell), which is less than the different system of A2 alien frequencies, redirects thresholding, different if less than A2 alien frequencies
System redirects thresholding, judges that the different system of A2 alien frequencies redirects whether thresholding is set rationally：Macro station [- 122~-126dBm]/room
Divide [- 118~-124dBm], if above this thresholding, it is determined that the blind redirection thresholding settings of A2 are excessively high.
8. operation judges are regular
Decision rule：In 5 minutes, pass through operation log (webmaster OMC- before and after the time point of event triggering>System->Day
Will management->Check operation note) with the presence or absence of user or modification PCI or modification interrupting service parameter is deactivated, if sentencing in the presence of if
Disconnected artificial modification parameter.
It should be understood that although the disclosure illustratively discusses as above judgment rule, above-mentioned judgement can be advised in practice
It is then adjusted, adds and reduces, more preferably to meet the problem of encountering in practice.
