As shown in Figure 1, be interference detection method schematic flow sheet in the embodiment of the present invention one, said method comprising the steps of:
Step 101: Reference Signal Received Power (the Reference Signal Receiving Power of each user terminal that disturbance detection equipment reception base station reports, RSRP) and Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR).
RSRP and the SINR of each user terminal that described base station reports to disturbance detection equipment determine by following steps:
The first step: base station receives each user terminal in the community of its service by measurement report (Measurement Report, the RSRP of the user terminal MR) reporting, Reference Signal Received Quality (Reference Signal Receiving Quality, RSRQ) and received signal strength indicator (Received Signal Strength Indicator, RSSI).
In the above-mentioned first step, each user terminal in community is according to the indication of network side, periodically measure RSRP, RSRQ and the RSSI of this community, and the sign of this user terminal and measurement result are carried to the base station that reports this community in measurement report, base station is when receiving measurement report, the carrier frequency of while this measurement report of recording carrying, the described carrier frequency carrier frequency that also this user terminal is used.
Because the user terminal in community is periodically to base station reporting measurement reports, therefore, same user terminal may be repeatedly to base station reporting measurement reports, and a plurality of different measurement report reporting of same user terminal can be distinguished according to the different time that receives measurement report in base station.
Second step: the RSRP of this user terminal to send up that base station receives according to this, RSRQ and RSSI determine the Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR) of this user terminal.
Concrete, base station receives also RSRP, RSRQ and the RSSI of recording user terminal to report, and records the time that this receives this user terminal to send up RSRP, RSRQ and RSSI simultaneously, and utilizes the SINR that determines this user terminal with formula (1):
Preferably, base station also reports disturbance detection equipment by the positional information of user terminal and the carrier frequency that uses.
Described positional information is that base station is determined according to the Timing Advance in the measurement report of user terminal to send up (Timing Advance, TA).
It should be noted that, in this step 101, be not limited to base station and determine the SINR of user terminal, also can be that base station sends to disturbance detection equipment by the RSRP of user terminal, RSRQ and RSSI, by disturbance detection equipment, utilize above-mentioned formula (1) to determine the SINR of this user terminal, base station can also send to disturbance detection equipment by the TA by measurement report of user terminal to send up, by disturbance detection equipment, according to TA value, determines the positional information of this user terminal.
Step 102: for RSRP and the SINR of each user terminal, disturbance detection equipment is determined the mass parameter of the RSRP of this user terminal according to the RSRP of this user terminal, determines the mass parameter of the SINR of this user terminal according to the SINR of this user terminal.
The mass parameter of described RSRP is for characterizing the quality level of the RSRP of user terminal, and the mass parameter of described SINR is for characterizing the quality level of the SINR of user terminal.
Disturbance detection equipment is determined the mass parameter of the RSRP of this user terminal according to the RSRP of this user terminal, the mass parameter of determining the SINR of this user terminal according to the SINR of this user terminal, specifically comprises:
Disturbance detection equipment determines that the affiliated numerical value of the RSRP of user terminal is interval, according to the interval mass parameter of determining RSRP of the numerical value under described RSRP, determine the mass parameter of the RSRP of user terminal, the mass parameter of described RSRP is for characterizing the quality level of the RSRP of user terminal;
Disturbance detection equipment determines that the affiliated numerical value of the SINR of user terminal is interval, and according to the interval mass parameter of determining SINR of the numerical value under described SINR, the mass parameter of described SINR is for characterizing the quality level of the SINR of user terminal.
Preferably, according to the interval mass parameter of determining SINR of the numerical value under described SINR, be specially:
According to the corresponding relation of the mass parameter of the numerical value interval of RSRP and RSRP, determine the mass parameter of RSRP;
According to the interval mass parameter of determining SINR of the numerical value under described SINR, be specially:
According to the corresponding relation of the mass parameter of the numerical value interval of SINR and SINR, determine the mass parameter of RSRP.
The numerical value interval of described RSRP sets in advance with the corresponding relation of the mass parameter of RSRP, numerical value interval and the corresponding relation of the mass parameter of SINR of SINR.
Concrete, according to the test result of LTE try net test, the numerical value of described RSRP interval can be as shown in table (1) with the corresponding relation of the mass parameter of RSRP; The numerical value interval of SINR can be as shown in table (2) with the corresponding relation of the mass parameter of SINR.
| Interval (the unit: dBm) of numerical value of RSRP | The mass parameter of RSRP |
| RSRP≥-85 | Fabulous |
| -85>RSRP≥-95 | Good |
| -95>RSRP≥-105 | In |
| -105>RSRP≥-115 | Poor |
Table (1)
| Interval (the unit: dB) of numerical value of SINR | The mass parameter of SINR |
| SINR≥20 | Fabulous |
| 20>SINR≥15 | Good |
| 15>SINR≥5 | In |
| 5>SINR≥-5 | Poor |
Table (2)
Utilize table (1) and table (2) below, to determine the mass parameter of the RSRP of this user terminal according to the RSRP of user terminal, according to the SINR of user terminal, determine that the mass parameter of the SINR of this user terminal is specifically described:
Suppose that the RSRP that user terminal 1 reports is-80dBm, SINR is 6dB, because-80dBm belongs to numerical value interval-85>RSRP >=-95 of RSRP, and the mass parameter of the RSRP of this numerical value interval-85>RSRP >=-95 correspondence is " good ", the mass parameter of the RSRP of the user terminal 1 of therefore, determining is " good "; Because 6dB belongs to interval 15>SINR >=5 of numerical value of SINR, and the mass parameter of the SINR of interval 15>SINR >=5 of this numerical value correspondence be " in ", the mass parameter of the SINR of the user terminal 1 of therefore, determining for " in ".
Step 103: for arbitrary user terminal, disturbance detection equipment relatively the mass parameter of the RSRP of this user terminal and the SINR mass parameter of this user terminal whether consistent, when inconsistent, determine that the corresponding comparative result of this user terminal is not for corresponding, when consistent, determine that the comparative result that this user terminal is corresponding is correspondence.
The RSRP that the user terminal 1 of still take reports is-80dBm, SINR is that 6dB is example, because the mass parameter of definite RSRP is " good ", and the mass parameter of definite SINR be " in ", therefore, to compare the mass parameter of RSRP and the SINR mass parameter of this user terminal of user terminal be inconsistent to disturbance detection equipment.
Certainly, above-mentioned be relatively the mass parameter of the RSRP of the user terminal determined be " good ", and the mass parameter of the SINR of this user terminal of determining is " good ", when also two mass parameters are identical, determine the mass parameter of RSRP of this user terminal and the SINR mass parameter of this user terminal for consistent be condition, the present invention does not limit to when to utilize two mass parameters be identical, determine that they are consistent, also can determine that whether two mass parameters are consistent according to actual conditions, such as: with the mass parameter of the RSRP of user terminal during lower than the mass parameter certain level (or certain grade) of the SINR of this user terminal, the mass parameter of RSRP and the SINR mass parameter of this user terminal of determining this user terminal are consistent.
Whether this step 103 relatively mass parameters of RSRP of user terminal consistent with the mass parameter of the SINR of this user terminal, and its essence is to utilize the incidence relation having between the RSRP of user terminal and the SINR of this user terminal, concrete, this be because of:
In LTE system, if the interference of the normal operation of the equipment in system and the interference-free signal of system, the RSRP of user terminal and the SINR of this user terminal have incidence relation, when the RSRP of user terminal numerical value is larger, the numerical value of the SINR of user terminal is also larger, and they are consistent.With above-mentioned table (1) and table (2), if the scope under the RSRP of user terminal (dBm of unit) is :-85>RSRP >=-95, now the SINR of this user terminal (dB of unit) must meet 20>SINR >=15.
According to the implication of above-mentioned incidence relation and RSRP and SINR itself, the in the situation that of base station and the equal normal operation of user terminal, can release as drawn a conclusion:
If the RSRP numerical value of user terminal is larger, show that base station is strong covering to the regional area at this user terminal place, now, if the SINR numerical value of this user terminal is less, shows likely to exist interference; If the RSRP numerical value of user terminal is larger, show that base station is strong covering to the regional area at this user terminal place, now, if the SINR numerical value of this user terminal is larger, shows not exist interference; And if the RSRP numerical value of user terminal is less, 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, can not determines whether to exist and disturb; Less for RSRP numerical value, and SINR numerical value is larger, this kind of situation is non-existent.
Known based on above-mentioned analysis, the in the situation that of base station and the equal normal operation of user terminal, the user terminal that the mass parameter of the RSRP of user terminal is not corresponding with the mass parameter of the SINR of this user terminal, the numerical value of RSRP that is this user terminal is larger, and the less user terminal of the numerical value of the SINR of this user terminal.
Step 104: disturbance detection equipment is determined the carrier frequency that user terminal is used, and judge whether to exist the comparative result corresponding to all user terminals of the same carrier frequency of use to be corresponding situation, if so, perform step 105, if not, perform step 106.
In this step 104, judgement exists the comparative result corresponding to all user terminals of the same carrier frequency of use to be corresponding situation and refers to, in all carrier frequency of determining, comparative result corresponding to user terminal under each carrier frequency is correspondence.
Before carrying out Interference Detection, needing to get rid of is corresponding situation because user terminal exists the comparative result that fault causes, also needing to get rid of because base station exists the comparative result that fault causes is not corresponding situation.Base station is when the RSRP to disturbance detection equipment transmission user terminal and RSRQ, and the carrier frequency information that also can simultaneously this user terminal be used sends to disturbance detection equipment.
Step 105: finish.
In this step 105, use the corresponding comparative result of user terminal of same carrier frequency to be correspondence, now can not determine that system does not exist interference, this be because: comparative result is at once, the mass parameter that may be the RSRP of user terminal is " good ", and the mass parameter of the SINR of this user terminal is also " good "; The mass parameter that may be also the RSRP of user terminal is " poor ", and the mass parameter of the SINR of this user terminal is also " poor "; But when the mass parameter of the RSRP of user terminal is " poor ", to show that base station is weak covering to the regional area at this user terminal place, the mass parameter of the SINR of user terminal is also " poor ", just can not determine it is that the mass parameter of the SINR that causes due to weak covering is " poor ", or the mass parameter of the SINR causing due to the existence of disturbing is " poor ", so can not decision-making system whether have interference.
Step 106: it is not corresponding whether disturbance detection equipment judgement is used the comparative result corresponding to all user terminals of same carrier frequency to be, and if not, performs step 107, if so, performs step 108.
Step 107: disturbance detection equipment determines that corresponding comparative result exists fault for not corresponding user terminal.
In this step 107, comparative result corresponding to certain customers' terminal under same carrier frequency be not at once, determine that this certain customers' terminal exists fault, this be because, because the channel that same user terminal under carrier frequency is used is essentially identical, and in the same area, the comparative result of other user terminals is corresponding, explanation be comparative result be not corresponding be that problem due to user terminal itself causes, there is fault for not corresponding user terminal in comparative result.
Step 108: whether disturbance detection equipment base stations detected exists fault, if so, performs step 109, if not, performs step 110.
Owing to breaking down in base station, also can cause the mass parameter of RSRP of user terminal and the mass parameter of the SINR of this user terminal not corresponding, in order to determine whether accurately to exist, disturb, therefore, in this step 108 to base station whether normally operation judge, to get rid of due to base station the break down mass parameter of RSRP of user terminal that causes and the not corresponding situation of the mass parameter of the SINR of this user terminal.
Step 109: determine that base station exists fault.
Step 110: disturbance detection equipment is determined the quantity that meets the user terminal imposing a condition in each region, and judges whether to exist described quantity whether to be greater than the region of predetermined threshold value, if so, performs step 111, if not, jumps to step 105.
Described impose a condition into: the mass parameter of the RSRP of user terminal is not corresponding with the mass parameter of the SINR of this user terminal.
Preferably, before this step 110, described method also comprises:
Disturbance detection equipment, according to the positional information of each user terminal receiving, is determined the region that each user terminal is affiliated.
Region under described each user terminal, residing region while being also each user terminal to send up measurement report.
Described region can be divided into for the microzonation in advance described base station being covered that N region obtain.
In this step 110, can be for the arbitrary region in N region, determine that the comparative result that in this region, user terminal is corresponding is not corresponding quantity, and judge that whether the quantity that the corresponding comparative result in this region is not corresponding user terminal is greater than predetermined threshold value, performs step 111 if be greater than.
Described predetermined threshold value can determine according to the quantity of user terminal in this region and network optimization situation, and quantity is larger, and predetermined threshold value is larger.Number is less, and predetermined threshold value is less; The network optimization is poorer, and predetermined threshold value is less, and the network optimization is better, and predetermined threshold value is less.
This step 110 is after getting rid of base station and user terminal fault, and the judgement that whether has interference of carrying out has improved 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, because disturbance detection equipment has utilized the RSRQ of all user terminal to send up in the community that base station covers, RSSI, RSRP, utilize the incidence relation between the RSRP of user terminal and the SINR of this user terminal whether to exist interference to determine to system, and the quantity that meets the mass parameter of RSRP of user terminal and the not corresponding user terminal of the mass parameter of the SINR of this user terminal in the normal operation of base station and user terminal and arbitrary region is while being greater than setting threshold, determine that system exists interference, therefore, can be objective, determine system comprehensively and accurately and whether have interference, in addition, base station can report jamming equipment by the RSRP of user terminal and SINR in real time, the interference that disturbance detection equipment exists in discovering network more timely.
