PCI is known, if the PCI is matched with the characteristic information, it is determined that disturb station to apply in the corresponding base station of the characteristic information.
Below with reference to scene embodiment, the present invention is described further.
In the present embodiment, telepoint base station (apply and disturb station) sends the characteristic sequence of load characteristic information in downlink symbol, closely
End group station (disturbed station) is detected in uplink symbol, as can characteristic sequence is arrived in inspection, then explanation receives far-end interference, and can
According to characteristic information location interference source base station.
When characteristic information is arranged, the whole or in which a part that can choose ECGI are used as characteristic information after being computed, with
For identifying interference source base station (apply and disturb station), such as: characteristic information=GetBit (ECGI), the processing of GetBit function include taking
Bit string, position adjustment and randomization etc., the bit that return value is length N goes here and there.
Wherein, the pseudo-random sequence with good autocorrelation can be used in the characteristic sequence, such as: ZC sequence, Gold sequence
Column or m-sequence etc..
In the present embodiment, the time domain (when transmission that the characteristic sequence ID, characteristic sequence are sent can be determined by characteristic information
Between) and frequency domain position.It is as follows:
In order to avoid excessive base station sends characteristic sequence simultaneously and detection performance is influenced, generallys use biggish transmission week
Phase, it is assumed that have Nt (default) a send opportunity in a sending cycle, then the sending time of characteristic sequence is represented by log2
(Nt) information of bit；
LTE system bandwidth is usually 20M, can be divided into a frequency domain of Nf (default) and send position, can be expressed as log2
(Nf) information of bit；
It is a that the characteristic sequence ID usually selects the weaker Ns of cross correlation (default) from sequence pond, in a transmitter
Transmission Nn (default) is secondary in meeting, then the combination that can pass through each transmission serial ID in a send opportunity indicates non-Nn*log2
(Ns) information of bit.By reasonable parameter combination, make log2(Nt)+log2(Nf)+Nn*log2(Ns) >=N (i.e. the sum of three
Not less than bit number shared by the characteristic information), such as: it can be by the low log of characteristic information2(Nt) a bit determines send opportunity,
Intermediate log2(Nf) a bit determines to send frequency domain position, reinforcement Nn*log2(Ns) a bit determines each transmission in send opportunity
Characteristic sequence ID.
Correspondingly, proximal end base station (disturbed station) is persistently detected in all possible positions for sending characteristic sequence of uplink,
Such as detect characteristic sequence, then it is assumed that receive far-end interference, characteristic information further can be obtained.If characteristic information length compared with
Long, the characteristic information of each base station ensures uniquely, then interference source can be accurately positioned based on characteristic information；If characteristic information is subject to processing
Complexity effect, length limited, characteristic information may be obscured, and need further to exclude duplicate message using relevant information:
1) duplicate message is excluded using characteristic sequence detection intensity, the information such as detection time-domain position and base station work ginseng in detail.
Such as: information can be joined by the work of base station, obtain the geographic distance between each candidate interference source base station and proximal end base station；Lead to simultaneously
Fine detection time of the characteristic sequence in subframe is crossed, such as: detection symbols position calculates the propagation distance of interference signal, usually
It is real jamming station that propagation distance, which is slightly larger than and is equal to the candidate stations of geographic distance,；
2) PCI of parsing interference base station is attempted in uplink symbol, while PCI and characteristic information is matched, substantially may be used
It excludes to repeat.
The above method individually can also can be used simultaneously.
The embodiment of the present invention is described below with reference to specific data.
Firstly, the selection of characteristic information and relative parameters setting are as follows:
1, characteristic information chooses rear 14 bit of base station IDs in the ECGI；
2, using each radio frames as a send opportunity, 1024 frames (i.e. 10.24S) are used as a sending cycle, i.e.,
Nt=1024 is represented by the information of 10bit；
3, characteristic sequence full frequency band is sent, i.e., only one transmission position, i.e. Nf=1 do not indicate bit information；
4, characteristic sequence ID totally 4, each send opportunity send 2 times, i.e. Ns=4, Nn=2, the feature sequence sent twice
ID totally 16 kinds of combinations are arranged, the information of 4bit is represented by.
Then, ID, sending time and the frequency domain position of characteristic sequence are determined according to above-mentioned parameter:
The characteristic information of certain telepoint base station is 1234, and corresponding binary system bit string is 00 0,100 1,101 0010, then its
Characteristic sequence send frame number by low level 10bit information, i.e., determined by " 00 1,101 0010 ", corresponding 10 system number is
210, i.e., characteristic sequence is sent in the radio frames that frame number is 210；Characteristic sequence ID is determined that " 00 01 " are right by the information of high 4bit
10 system numbers 1 are answered, i.e., sends (subframe 1) for the first time and sends the characteristic sequence that serial ID is 0, send (subframe 6) for the second time and send
The characteristic sequence that serial ID is 1.
Correspondingly, certain proximal end base station can reversely calculate after the above-mentioned time point of uplink symbol detects this feature sequence
The characteristic information bit string of interference source base station is that " 00 0,100 1,101 0010 " (can be according to expression characteristic sequence ID, transmission out
The bit number of time and frequency domain position is combined into the bit string of characteristic information), because not indicating whole eNBID information, it is understood that there may be mixed
Confuse, obscures in combination with work ginseng and the exclusion of detailed detection time, interference source is accurately positioned.
The remote interference source including atmospheric duct interference can be accurately positioned in the embodiment of the present invention based on characteristic information,
To targetedly optimize, network performance is promoted.In addition, other than characteristic information, it can also the inspection of supplemental characteristic sequence
It surveys intensity, detect the remote interference sources of Information locatings such as time-domain position, base station work ginseng and/or PCI in detail, position more accurate.
