In above-mentioned steps 201, the terminal under cell to be detected is divided for L classes by base station, wherein, value and the measurement of L
Terminal quantity M under cycle, time of measuring interval and cell to be detected has relation.
For example, when measure the cycle is 40ms, (each terminal needs to be done in 6ms when time of measuring is at intervals of 6ms
Disturb detection), the quantity at the time of measuring interval in measure the cycleFor another example, when measure the cycle is 80ms,
When time of measuring is at intervals of 6ms, the quantity at the time of measuring interval in measure the cycle
As quantity Ns of the terminal quantity M more than or equal to time of measuring interval, then M terminal can be divided into L classes,

Illustrated with reference to a specific example.It is measure the cycle provided in an embodiment of the present invention with reference to Fig. 3
Time of measuring is spaced schematic diagram.Wherein, measure the cycle is 40ms, time of measuring at intervals of 6ms, then during measurement in measure the cycle
Between be spaced quantityAnd the terminal quantity M=20 in cell to be detected, M terminal is divided into 6 classes,
Such as the 1st Terminal Type includes 3 terminals, and the 2nd Terminal Type includes 3 terminals, and the 3rd Terminal Type includes 3 terminals, the 4th Terminal Type
Comprising 3 terminals, the 5th Terminal Type includes 3 terminals, and the 6th Terminal Type includes 5 terminals.
Base station issues frequency metrical information to this 20 terminals, inclined comprising frequency to be detected, measurement in frequency metrical information
The time is put, wherein, the measurement offset time that the terminal in same class is received is identical, the measurement that the terminal in inhomogeneity is received
Offset time is different, and includes one or more terminals in every Terminal Type, it is assumed that frequency to be detected is frequency d, then to this 6 class end
The frequency metrical information that end issues is as follows respectively：
It is handed down in the frequency metrical information of the 1st Terminal Type and includes：Frequency d, measures offset time 0；
It is handed down in the frequency metrical information of the 2nd Terminal Type and includes：Frequency d, measures offset time 6；
It is handed down in the frequency metrical information of the 3rd Terminal Type and includes：Frequency d, measures offset time 12；

It is handed down in the frequency metrical information of the 5th Terminal Type and includes：Frequency d, measures offset time 24；
It is handed down in the frequency metrical information of the 6th Terminal Type and includes：Frequency d, measures offset time 30.
In other situations, as quantity Ns of the terminal quantity M less than time of measuring interval, then L=M, i.e. by M
Terminal is divided into M classes, per one user of class；Also, in this case, base station can repeatedly be sent out to the terminal in region to be detected
Frequency metrical information is sent so that there is the terminal to carry out interferometry in each time of measuring in measure the cycle interval, so that reality
It is now that terminal is fully dispersed interior to each time of measuring interval, for example, by taking Fig. 3 as an example, the number that wherein time of measuring is spaced
Amount N=6, it is assumed that terminal quantity M=4, then L=4, will 4 terminals be divided into 4 classes, per 1 terminal of class, then base station the 1st time is to treating
4 Terminal Types in measurement cell send frequency metrical information respectively, for example：
It is handed down in the frequency metrical information of the 1st Terminal Type and includes：Frequency d, measures offset time 0；
It is handed down in the frequency metrical information of the 2nd Terminal Type and includes：Frequency d, measures offset time 6；
It is handed down in the frequency metrical information of the 3rd Terminal Type and includes：Frequency d, measures offset time 12；
It is handed down in the frequency metrical information of the 4th Terminal Type and includes：Frequency d, measures offset time 18；
Then, base station is again at random to the 2nd transmission frequency metrical information of two Terminal Types (e.g. the 1st class and the 4th class), example
Such as：
It is handed down in the frequency metrical information of the 1st Terminal Type and includes：Frequency d, measures offset time 24；
It is handed down in the frequency metrical information of the 4th Terminal Type and includes：Frequency d, measures offset time 30.
So as in each time of measuring interval that terminal is distributed in measure the cycle.
It should be noted that, it is necessary at least send frequency metrical information twice, sheet to terminal under above-mentioned second case
In inventive embodiments, as long as ensureing that the frequency metrical information for sending twice can cover all time of measuring intervals, and it is right
Which measured using terminal after second or second, the embodiment of the present invention is also not specifically limited.

In step 203, terminal determines the time of measuring interval in measure the cycle, and the measurement adjacent cell in time of measuring interval
RSRP。
Specifically, for each terminal in cell to be measured, before adjacent cell frequency measurement is carried out, measurement is worked as
The RSRP of preceding Serving cell, is designated as RSRPlocal, when terminal determines that reaching the time of measuring of oneself is spaced, then in the survey of oneself
The measurement of adjacent cell RSRP is carried out in amount time interval, for example, for any terminal in the 3rd Terminal Type shown in Fig. 3,
When 12ms is reached, any terminal in the 3rd Terminal Type is detected and reaches the time of measuring interval of oneself, therefore starts measurement
The RSRP of the adjacent cell being operated under frequency to be detected, when the RSRP for detecting adjacent cell is more than or equal to threshold value, then
Report to base station.
In above-mentioned steps 204, the RSRP of the Serving cell that terminal will be measured and the RSRP of adjacent cell are sent to base station.Cause
This, finally in base station side, for each terminal, can receive the following information of terminal transmission：
RSRP, i.e. RSRP of the terminal in Serving celllocal, and the adjacent cell that measures of the terminal not less than thresholding
The RSRP values of threshold value, for example, have：RSRP1 1, RSRP1 2... ..., RSRP2 1, RSRP2 2... ..., RSRP3 1, RSRP3 2... ..., its
In, RSRPi jJ-th of the i-th adjacent cell RSRP, i=1,2 more than threshold value that expression is measured, 3 ... ..., j=1,2,
3 ... ....
In above-mentioned steps 205, base station setting duration in receive the Serving cell that each terminal is reported respectively RSRP and
The RSRP of adjacent cell.
In above-mentioned steps 206, base station according to the RSRP of the Serving cell of all terminal to report and RSRP of adjacent cell, it is determined that
Whether the frequency to be detected is interference frequency.
Specifically 3, base station determines whether the frequency to be detected is interference frequency by following manner, including：
For each terminal, base station determines Signal to Interference plus Noise Ratio of the terminal in frequency to be detected, and according to all terminals to be checked
The Signal to Interference plus Noise Ratio of frequency measurement point, determines whether frequency to be detected is interference frequency.
Wherein it is determined that a terminal is in the specific method of the Signal to Interference plus Noise Ratio of frequency to be detected：
The RSRP of the adjacent cell according to terminal to report, determines the adjacent cell synthesis RSRP of terminal, and according to the terminal
Serving cell RSRP and the terminal the frequency to be detected adjacent cell synthesis RSRP.
For example, terminal to report RSRP of multiple adjacent cells, and the RSRP of each adjacent cell for reporting has multiple, then
Base station by terminal all RSRP of each adjacent cell average value, as terminal the adjacent cell target RSRP；And
The summation of the target RSRP of each adjacent cell that will be determined, as the adjacent cell synthesis RSRP of terminal.
Then, by the difference of the RSRP of the Serving cell of the terminal and adjacent cell synthesis RSRP of terminal, treated as terminal
Detect the Signal to Interference plus Noise Ratio of frequency.
Illustrated with reference to a specific example.
Assuming that terminal A has RSRP to the data that base station reportslocalAnd RSRP1 1, RSRP1 2... ..., RSRP2 1,
RSRP2 2... ..., RSRP3 1, RSRP3 2... ..., then the adjacent cell synthesis RSRP of terminal is calculated first, RSRP can be usedneibour
To represent, thenWherein, NumiNot less than door in i-th adjacent area that expression is measured
The quantity of the RSRP of limit value.
And then, by RSRPlocalWith RSRPneibourDifference, as terminal A frequency to be detected Signal to Interference plus Noise Ratio.
By the above method, the corresponding Signal to Interference plus Noise Ratio of each terminal can be calculated.
