Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only part of the embodiment of the present invention, is not
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that is obtained, belong to the scope of protection of the invention.
In order to improve the validity of F-band interference investigation, in the embodiment of the present invention, a radio frames are received
When, any one special subframe included in radio frames is determined, and obtain in any one above-mentioned special subframe
The interference measure of each free physical resource block specified (Physical Resource Block, PRB)
(IOT), and the idle PRB that IOT is more than given threshold is filtered out, and judges the idle PRB filtered out
Number whether be more than the first preset number, disturbed if so, then judging to exist outside system, otherwise, it is determined that depositing
The interference or noiseless in system.
The present invention program is described in detail below by specific embodiment, certainly, the present invention is not limited to
Following examples.
As shown in fig.1, in the embodiment of the present invention, TD-LTE system disturbs the idiographic flow of determination methods
It is as follows：
Wherein, in the embodiment of the present invention, illustrated so that the interference of TD-LTE system F-band judges as an example.
What deserves to be explained is the interference of TD-LTE system F-band can be divided into the interior interference of system and system is dry outside
Disturb.Wherein,
Disturbed in system and be：With networking between frequency, adjacent cell customer service signal is by the IOT liftings of this cell.
Being disturbed outside system can be divided into again：
1) second harmonic of Band8 900MHz GSM signals, interfering frequency scope are
1850-1920MHz, whole F-band (i.e. GSM900 interference) is covered substantially.
2) (i.e. DCS1800 is done the rank intermodulation signal of 3 rank 5 of Band3 1800MHz DCS signals
Disturb).
3) Band3 FDD-LTE neighboring trace, secondary neighboring trace spurious signal (i.e. clutter interference).
4) Band3 FDD-LTE signal jam (i.e. obstruction interference).
Therefore, it is necessary to which what the interference source for judging F-band is, and then can be handled accordingly.
Step 100：When receiving a radio frames, any one for determining to include in above-mentioned radio frames is special
Subframe, and obtain the IOT for the idle PRB that each in any one above-mentioned special subframe is specified.
In practice, at present in TD-LTE system, for a radio frames, special subframe has the He of subframe 1
Subframe 6, when carrying out interference and judging, each idle PRB of subframe 1 or subframe 6 IOT can be counted.
Wherein, for TD-LTE system, if any one above-mentioned special subframe is subframe 1, refer to
Fixed idle PRB is preceding 4 PRB of subframe 1；If any one above-mentioned special subframe is subframe 6,
The idle PRB specified is 4 PRB after subframe 6.
Wherein, when obtaining each idle PRB specified IOT in any one above-mentioned special subframe,
Specifically include：
According to predetermined period, each idle PRB specified in any one above-mentioned special subframe is obtained
IOT。
Wherein, predetermined period, for example, can be every a hour, one day 0 point to 24 points, totally 24
The individual period, for investigating F-band disturbed condition.
That is, when performing step 100, following two situations can be specifically divided into：
The first situation：According to predetermined period, preceding 4 PRB of acquisition subframe 1 IOT.
Second of situation：According to predetermined period, rear 4 PRB of acquisition subframe 6 IOT.
Step 110：According to each above-mentioned idle PRB specified IOT, IOT is filtered out more than first
The idle PRB of given threshold, and whether the number for the idle PRB for judging to filter out is more than the first present count
Mesh, disturbed if so, then judging to exist outside system, otherwise, it is determined that interference or noiseless in system be present.
When performing step 110, specifically include：
First, according to each idle PRB specified IOT, IOT is filtered out more than the first setting threshold
The idle PRB of value.
Wherein, preferable first given threshold is -105dBm.
Then, whether the number for the idle PRB for judging to filter out is more than the first preset number, if so, then
Judgement is present to be disturbed outside system, otherwise, it is determined that interference or noiseless in system be present.
Wherein, due to having 4 for subframe 1 or subframe 6, idle PRB, therefore, the first preset number
Preferably 3.
Because for TD-LTE system F-band, be according to the idle PRB specified of special subframe come
Carry out disturbing judgement, idle PRB is not used in the information transfer in TD-LTE system, therefore, works as the free time
When PRB IOT is more than the first given threshold, it is possible to determine that whether be to be disturbed outside system, and remove outside system
The situation of interference, interference or noiseless in system is construed as, particularly for interference in system or without dry
Disturb to be judged using other means again.
So, by preceding 4 PRB of subframe 1 IOT or rear 4 PRB of subframe 6 IOT,
It can tentatively judge it is interference or the interior interference or noiseless of system outside system.
Further, it is necessary to judge to disturb outside specially any system again, tool after execution of step 110
Body is：Obtain all PRB of any one above-mentioned special subframe IOT.
And then interference judgement is carried out, following two situations can be divided into：
The first situation：According to above-mentioned all PRB IOT, IOT is filtered out more than the above-mentioned first setting
The PRB of threshold value, and whether the number for the PRB for judging to filter out is more than the second preset number, if so, then
Judge to disturb outside said system and disturbed for obstruction, otherwise, it is determined that it is clutter interference to be disturbed outside said system.
In practice, for different bandwidth, the PRB number that subframe includes is different, for example, 20M
It is 200, therefore, the second present count for all PRB numbers of subframe 1 or subframe 6 under bandwidth
Mesh is preferably 150, naturally it is also possible to is other numerical value, can specifically be set according to actual conditions.
That is, in working as all 200 PRB for determining subframe 1 or subframe 6, at least 150
When PRB IOT is more than -105dBm, it is determined as obstruction interference, however, it is determined that be unsatisfactory for being determined as that obstruction is dry
The condition disturbed, then all it is determined as clutter interference.
Second of situation：According to above-mentioned all PRB IOT, however, it is determined that the PRB of the 3rd preset number be present
IOT values of the IOT higher than remaining PRB be more than the second given threshold, then judge interference outside said system
For GSM900 interference or DCS1800 interference.
Wherein, the 3rd preset number, preferably 1,2 or 3.
That is, when most of PRB IOT all than it is relatively low when, only 1-3 PRB IOT is bright
It is aobvious higher than remaining PRB IOT, and the value of the IOT higher than remaining PRB is more than the second given threshold, then
It is determined as GSM900 interference or DCS1800 interference, wherein, the second given threshold can be according to reality
Situation is set, for example, getting all PRB IOT, is learnt, most of PRB IOT is
Have obvious rise in -120dBm or so, only 3 PRB IOT, for example, be respectively -100dBm,
- 103dBm and -98dBm, then it is considered that this 3 PRB IOT is higher than remaining PRB IOT's
Value is more than the second given threshold, it is possible to determine that for GSM900 interference or DCS1800 interference.
Wherein, GSM900 interference or DCS1800 interference, it is embodied in GSM900 second harmonic
Interference, the intermodulation distortion of DCS1800 interference.
So, according to the idle PRB specified of special subframe judge F-band with the presence or absence of disturb outside system,
Interference is noiseless in system, is determined as after being disturbed outside system, further according to all PRB of special subframe, judges
Go out the particular type disturbed outside system, can rapidly and accurately judge the interference of TD-LTE system F-band
Situation, and then can be handled accordingly according to different interference sources.
Further description is made to above-described embodiment using a specific application scenarios below.Specific ginseng

Frame, and according to predetermined period, obtain the idle PRB that each in any one above-mentioned special subframe is specified
IOT.
Wherein, any one above-mentioned special subframe can be subframe 1, or subframe 6.
Wherein, if subframe 1, then the idle PRB specified is preceding 4 PRB of subframe 1；If subframe
6, the then idle PRB specified are rear 4 PRB of subframe 6.
Step 201：It is pre- to judge whether numbers of the IOT more than the idle PRB of the first given threshold is more than first
If number, if so, then performing step 203, otherwise, step 202 is performed.
Wherein, the first given threshold is, for example, -105dBm, and the first preset number is, for example, 3.
Step 202：It is determined as interference or noiseless in system.
Step 203：It is judged to disturbing outside system.
Step 204：Obtain all PRB of any one above-mentioned special subframe IOT.
So, determined whether by all PRB of any one above-mentioned special subframe disturbed condition be
The type of the outer interference of system.
Step 205：Judge whether IOT is more than the second present count more than the PRB of the first given threshold number
Mesh, if so, then performing step 206, otherwise, perform step 207.
Wherein, if all PRB of any one above-mentioned special subframe are 200, the second preset number
For example, 150.
Step 206：Disturbed outside decision-making system as obstruction interference.
Step 207：It is clutter interference to be disturbed outside decision-making system.
Step 208：Judge that the IOT of the PRB in all PRB with the presence or absence of the 3rd preset number is higher than it
