Table (2)
Below with table (1) and table (2), the RSRP according to user terminal is determined this user terminal
The mass parameter of RSRP, determines the mass parameter of the SINR of this user terminal according to the SINR of user terminal
It is specifically described:
Assuming that the RSRP that user terminal 1 reports is-80dBm, SINR is 6dB, then belong to due to-80dBm
Numerical intervals-85 in RSRP > RSRP >=-95, and this numerical intervals-85 > RSRP >=-95 correspondence
The mass parameter of RSRP is " good ", accordingly, it is determined that the mass parameter of the RSRP of the user terminal 1 gone out is
" good "；Owing to 6dB belongs to the numerical intervals 15 of SINR > SINR >=5, and this numerical intervals 15 > SINR >=5
The mass parameter of corresponding SINR be " in ", accordingly, it is determined that the quality of the SINR of the user terminal 1 gone out
Parameter be " in ".
Step 103: for any user terminal, disturbance detection equipment compares the RSRP's of this user terminal
Mass parameter is the most consistent with the SINR mass parameter of this user terminal, when inconsistent, determines this user
Comparative result corresponding to terminal is the most corresponding, when consistent, determines the comparative result that this user terminal is corresponding
For correspondence.
The RSRP still reported with user terminal 1 is-80dBm, as a example by SINR is 6dB, due to determine
The mass parameter of RSRP is " good ", and the mass parameter of the SINR determined for " in ", therefore, interference
Detection equipment compares the mass parameter of the RSRP of user terminal and the SINR mass parameter of this user terminal
It is inconsistent.
Certainly, above-mentioned compare be the mass parameter of the RSRP with the user terminal determined be " good ", and really
The mass parameter of the SINR of this fixed user terminal is " good ", namely when two mass parameters are identical, determines
The mass parameter of the RSRP of this user terminal is consistent for condition with the SINR mass parameter of this user terminal
, when the present invention does not limit to that to utilize two mass parameters be identical, determine that they are consistent, it is also possible to
Determine that two mass parameters are the most consistent, such as: with the matter of the RSRP of user terminal according to practical situation
When amount parameter is less than mass parameter certain level (or certain grade) of the SINR of this user terminal, determine
The mass parameter of the RSRP of this user terminal is consistent with the SINR mass parameter of this user terminal.
This step 103 compares the matter of the mass parameter of the RSRP of user terminal and the SINR of this user terminal
Amount parameter is the most consistent, and its essence is to utilize between the RSRP of user terminal and the SINR of this user terminal
The incidence relation having, concrete, this is because:
In LTE system, if the equipment in system is properly functioning and the interference of the interference-free signal of system, use
The RSRP of family terminal and the SINR of this user terminal has incidence relation, at the RSRP of user terminal
When numerical value is bigger, the numerical value of the SINR of user terminal is the biggest, and i.e. they are to maintain consistent.With above-mentioned
For table (1) and table (2), if the RSRP of user terminal (unit dBm) belonging in the range of:
-85 > RSRP >=-95, now the SINR (unit dB) of this user terminal must meet 20 > SINR >=15.
According to above-mentioned incidence relation and the implication of RSRP and SINR itself, equal in base station and user terminal
In the case of normal operation, can release and such as draw a conclusion:
If the RSRP numerical value of user terminal is relatively big, then show the base station regional area to this user terminal place
It is strong covering, now, if the SINR numerical value of this user terminal is less, then shows to there may exist interference；
If the RSRP numerical value of user terminal is relatively big, then show that base station is strong to the regional area at this user terminal place
Cover, now, if the SINR numerical value of this user terminal is relatively big, then show to there is not interference；And if using
The RSRP numerical value of family terminal is less, then show that base station is weak covering to the regional area at this user terminal place
, now, if the SINR numerical value of user terminal is less, then can not determine whether to there is interference；For RSRP
Numerical value is less, and SINR numerical value is relatively big, and this kind of situation is non-existent.
Understand based on above-mentioned analysis, in the case of the equal normal operation in base station and user terminal, user terminal
The user terminal that the mass parameter of RSRP is the most corresponding with the mass parameter of the SINR of this user terminal, is
The numerical value of the RSRP of this user terminal is relatively big, and user's end that the numerical value of the SINR of this user terminal is less
End.
Step 104: disturbance detection equipment determines the carrier frequency that user terminal is used, and judges whether to make
It is the situation of correspondence with the comparative result that all user terminals of same carrier frequency are corresponding, the most then performs step
Rapid 105, if it is not, then perform step 106.
In this step 104, it is judged that exist and use the comparative result corresponding to all user terminals of same carrier frequency equal
Refer to for corresponding situation, in all carrier frequency determined, the comparison that user terminal under each carrier frequency is corresponding
Result is correspondence.
Before carrying out Interference Detection, it is right for needing to get rid of because user terminal exists the comparative result that fault causes
Situation about answering, it is also desirable to getting rid of the comparative result caused because base station there is fault is the most corresponding situation.Base
Stand in when disturbance detection equipment sends RSRP and RSRQ of user terminal, it is also possible to simultaneously by this user
The carrier frequency information that terminal is used is sent to disturbance detection equipment.
Step 105: terminate.
In this step 105, the comparative result corresponding to the user terminal of same carrier frequency is used to be correspondence, this
Time can not determine that system does not exist interference, this is because: comparative result is user during correspondence
The mass parameter of the RSRP of terminal is " good ", and the mass parameter of the SINR of this user terminal is also " good "；
The mass parameter of the RSRP being also likely to be user terminal is " poor ", the quality ginseng of the SINR of this user terminal
Number is also " poor "；But when the mass parameter of the RSRP of user terminal is " poor ", it is to show base station pair
The regional area at this user terminal place is weak covering, and the mass parameter of the SINR of user terminal is also
" poor ", cannot determine that the mass parameter of the SINR caused due to weak covering is " poor ", or due to
The mass parameter of the SINR that the existence of interference causes is " poor ", therefore decision-making system whether can not there is interference.
Step 106: disturbance detection equipment judges the comparison knot that all user terminals of the same carrier frequency of use are corresponding
It is the most corresponding whether fruit is, if it is not, then perform step 107, the most then performs step 108.
Step 107: disturbance detection equipment determines that the user terminal that corresponding comparative result is the most corresponding exists fault.
In this step 107, when comparative result corresponding to certain customers' terminal under same carrier frequency is not to correspondence
I.e. determine that this certain customers' terminal exists fault, this is because, due to the same institute of user terminal under carrier frequency
The channel used is essentially identical, and in the same area, the comparative result of other user terminals is corresponding,
Then explanation be comparative result be the most corresponding be owing to the problem of user terminal itself causes, i.e. comparative result is
The most corresponding user terminal occurs in that fault.
Step 108: whether disturbance detection equipment detection base station exists fault, the most then perform step 109,
If it is not, then perform step 110.
Owing to when breaking down in base station, also resulting in mass parameter and this user of the RSRP of user terminal
The mass parameter of the SINR of terminal is the most corresponding, in order to determine whether there is interference, therefore, this step accurately
In rapid 108, the most properly functioning of base station is judged, break down due to base station with eliminating and cause
The mass parameter of RSRP of user terminal feelings the most corresponding with the mass parameter of the SINR of this user terminal
Condition.
Step 109: determine that base station exists fault.
Step 110: disturbance detection equipment meets the quantity of the user terminal imposed a condition in determining each region,
And judge whether whether described quantity is more than the region of predetermined threshold value, the most then perform step 111,
If it is not, then jump to step 105.
Described impose a condition as: the mass parameter of the RSRP of user terminal with the SINR's of this user terminal
Mass parameter is the most corresponding.
Preferably, before this step 110, described method also includes:
Disturbance detection equipment, according to the positional information of each user terminal received, determines belonging to each user terminal
Region.
Region belonging to described each user terminal, is also district residing during each user terminal reporting measurement reports
Territory.
Described region can be in advance the community that described base station covers to be divided into N number of region to obtain.
Then in this step 110, this district's intra domain user can be determined for any region in N number of region
Comparative result corresponding to terminal is the most corresponding quantity, and judges that the corresponding comparative result in this region is not as
The quantity of corresponding user terminal, whether more than predetermined threshold value, if being more than, performs step 111.
Described predetermined threshold value can determine according to quantity and the network optimization situation of user terminal in this region,
Quantity is the biggest, and predetermined threshold value is the biggest.Number is the least, and predetermined threshold value is the least；The network optimization is the poorest, presets threshold
Being worth the least, the network optimization is the best, and predetermined threshold value is the least.
This step 110 is that whether carry out exists sentencing of interference after getting rid of base station and user terminal fault
Disconnected, improve the accuracy of judged result.
Step 111: disturbance detection equipment determines that system exists interference, sends interference warning information.
The embodiment of the present invention one provides a kind of interference detection method, owing to disturbance detection equipment make use of base station
