As shown in Figure 1, Fig. 1 shows the flow diagram of uplink interference localization method provided in an embodiment of the present invention.Its
May include：
S101：According to the average value of the interference noise detected on each PRB of uplink of base station statistics, uplink interference is determined
Residing range；
S102：By SINR, the corresponding uplink interference intensity of RSRQ of each sampled point in the MR that UE is reported is calculated；
S103：According to uplink interference intensity and RSRP, the first sampled point set is determined；
S104：According to range residing for the first sampled point set and uplink interference, the second sampled point set is determined；
S105：It is default by being less than in the second sampled point set and at a distance from the destination sample point in the second sampled point set

System measures bottom per Transmission Time Interval TTI on each PRB of uplink and makes an uproar the general power interfered with adjacent area, and
It is averaging in PRB ranks, obtains the sub-wave length interference noise power of each PRB, using this value as a sample point.It is counting
All end of term, take the maximum value of each sample point in the period as the PRB grades interference noise detected on each PRB of system uplink most
Big to be worth, the average value of each sample point is as the flat of the PRB grade interference noises detected on each PRB of system uplink in calculating cycle
Mean value L.UL.Interference.Avg.In practical applications, fixed condition can be range residing for uplink interference really：
L.UL.Interference.Avg is more than -118dBm (dBm/decibel millivolt).According to L.UL.Interference.Avg
Uplink interference can be determined in the coverage area (i.e. range residing for uplink interference) of one or more cells.Wherein, the uplink
The residing range of interference is only the approximate location of uplink interference.
RSRQ reactions UE receives the Reference Signal Received Quality of serving cell, cannot directly characterize interference strength.SINR is used
In gauge signal quality.The SINR used in TD-LTE system planning index is the SINR of cell common reference signal, SINR mono-
As value range be -5dB~25dB, it will be more than 95% that existing TD-LTE system, which requires the probability of cell edge SINR > -3dB,.
It is related to three aspect of useful signal, interference signal and noise due to calculating SINR, noise is to be relatively fixed and be unable to control, greatly certainly
Right noise is -174dBm/Hz, and the noise level of computing device also needs to add noise coefficient, and general base station side noise coefficient is
4dB, end side 7dB；The downlink reference signal RSRP that terminal receives is combined with noise and terminal can be obtained receives interference
The size of value.
Therefore the corresponding uplink interference intensity of RSRQ of each sampled point in MR can be calculated by SINR.
Specifically, RSRQ=N*RSRP/RSSI (1)
Wherein, N is the quantity of current bandwidth PRB；RSRP is Reference Signal Received Power；RSSI is carrier received signal field
Strong instruction.
Assuming that the power of data subcarrier is P, the power of pilot sub-carrier is 2P；For the PRB being not used by, only two
A pilot sub-carrier has power, therefore the PRB power is 2*2P=4P；For the PRB having been used, there are 12 on each PRB
Subcarrier, wherein there are 10 power for the data subcarrier of P, the pilot sub-carrier that 2 power are 2P, therefore the PRB power is
10*P+2*2P=14P.
Assuming that current bandwidth PRB quantity is N, wherein X PRB is used, and Y PRB is not used by.At this point,
RSRQ=(N*2P)/(X*14P+Y*4P+12*N*NI) (2)
Wherein, NI is the mean power of each subcarrier.
X+Y=N (3)
NI/2P=1/SINR (4)
It is by 2 abbreviation of formula using formula 3 and formula 4：
RSRQ=1/ (2+5X/N+12/SINR) (5)
That is RSRQ=-10log (2+5X/N+12/SINR) dB (decibel) (6)
SINR=10log12-10log { 1/ [power (10, RSRQ/10)] -2-5 (X/N) } (7)
Wherein, power (10, RSRQ/10) indicates 10 side RSRQ/10.
When unloaded (i.e. no PRB is used X=0), RSRQ=-10log (2+12/SINR) dB.
When fully loaded (i.e. N number of PRB is used X=N), RSRQ=-10log (7+12/SINR) dB.
When SINR positive infinitys, when there is no load, RSRQ=-3dB.
Work as SINR=-8dB, at full capacity when, RSRQ=-19.5dB.
When mono- timings of RSRQ it can be seen from formula 6 and formula 7, full load SINR is best, and SINR is worst when unloaded.When
When RSRQ is less than -14.9dB, the difference of both unloaded SINR and fully loaded SINR are less than 1, and unloaded SINR is approximately considered in calculating
It is equal with actual load SINR, from there through SINR, the corresponding uplink interference intensity of RSRQ of each sampled point in MR is calculated, i.e.,
The RSRQ in MR is converted to SINR to simulate uplink interference intensity.
The embodiment of the present invention determines the first sampled point set according to uplink interference intensity and RSRP, can be by uplink interference
Intensity is less than default second threshold and RSRP is more than the corresponding sampled point of default third threshold value, is determined as the first sampled point set.
Specifically, the sampled point quality of reception that the RSRQ values filtered out are less than default second threshold is poor, the SINR value of characterization
Also poor, the RSRP values filtered out are not belonging to cell edge more than the sampled point of default third threshold value and cover very poor sampled point.
The embodiment of the present invention determines the second sampling point set according to range residing for the first sampled point set and uplink interference
It closes, can specifically include：

Illustratively, it is assumed that include 2 sampled points, respectively sampled point A and sampled point B in serving cell, will first sample
Point A is set as pending sampled point, calculates the RSRP differences of the sampled point in the adjacent cell of sampled point A and serving cell, if
The minimum value for the difference being calculated is less than default 4th threshold value, one sampled point A is determined as in third sampled point set
Sampled point；Sampled point B is set as pending sampled point again, calculates the sampled point in the adjacent cell of sampled point B and serving cell
RSRP differences sampled point B is determined as third sampling if the minimum value for the difference being calculated is less than default 4th threshold value
A sampled point in point set.After the completion of all sampled points in serving cell calculate, third sampled point set is obtained.At this time
Third sampled point set in sampled point overlapping level of coverage it is high, overlapping level of coverage height herein refers to by system descending signal
It is interfered caused by overlapping covering.
From the sampled point rejected in the first sampled point set in third sampled point set, obtain existing only in the first sampled point
Gather but be not present in the sampled point of third sampled point set.
Further, for each sampling for being present in the first sampled point set but being not present in third sampled point set
Point obtains GPS longitudes and latitude；The GPS warps being located at from screening in the GPS longitudes and latitude of acquisition in range residing for uplink interference
Degree and latitude；The GPS longitudes and the corresponding sampled point of latitude that screening is obtained, are determined as the second sampled point set.
The embodiment of the present invention is according to model residing for the first sampled point set and uplink interference it can be seen from the above process
It encloses, determines the second sampled point set, can will directly exist simultaneously in the range residing for uplink interference and the first sampled point set
