In embodiments of the present invention, the wireless communication system can be 3G communication system, such as LTE system, be also possible to
4G communication system, new wireless (New Radio, NR) system or other require the communication system of time synchronization, it is just different herein
One schematically illustrates.In the following description, will be using the wireless communication system as LTE system, and the method is applied to LTE system
For management station in system, method provided in an embodiment of the present invention to be described in detail.The management station specifically can be
Some base station in the LTE system is also possible to the equipment dedicated for managing base station, herein with no restrictions.
When detecting the out-of-sync cells GPS using the technical solution in the embodiment of the present invention, step S101 is first carried out, it may be assumed that really
Determine the changing rule of the jamming power of the sub-frame of uplink of wireless network cell in wireless communication system；Wherein, the sub-frame of uplink
Jamming power be the sub-frame of uplink symbol power and the sub-frame of uplink signal power difference.
In embodiments of the present invention, the specific implementation of step S101 is as follows:
A1 obtains in N number of sub-frame of uplink in the wireless network cell each sub-frame of uplink in default frequency domain dispatching
M jamming power of M interior symbol；Wherein, M, N are positive integer；
A2 determines average interference power of each symbol in N number of sub-frame of uplink in the M symbol；
A3, the average interference power based on each symbol in N number of sub-frame of uplink, determines the wireless network
The changing rule of the jamming power of the sub-frame of uplink of cell.
In the specific implementation process, for detecting the wireless network cell A in LTE system and whether be the out-of-sync cells GPS
It is illustrated.In order to accurately detect the jamming power of the sub-frame of uplink in the A of wireless network cell, the management of LTE system
It stands firstly the need of N number of sub-frame of uplink is obtained from the A of wireless network cell, which specifically can be preset time period
Interior multiple sub-frame of uplink, for example, all sub-frame of uplink in 2 minutes in the A of wireless network cell；It is also possible to pre-set
The numerical value of N obtains any N number of sub-frame of uplink, certainly from the A of wireless network cell；It is also possible to using other modes acquisition,
This is not restricted.Then, the management station of LTE system then carries out jamming power measurement to N number of sub-frame of uplink.Of the invention real
It applies in example, the measurement method of jamming power is as follows:
1) general power of each symbol of each sub-frame of uplink in N number of sub-frame of uplink within the frequency domain dispatching time is determined.
In LTE system, a sub-frame of uplink includes 14 symbols on frequency domain, then management station needs to N number of uplink
14 symbols in each sub-frame of uplink in frame carry out jamming power measurement.To calculate in sub-frame of uplink 1 the dry of 14 symbols
For disturbing power, the jamming power of any symbol are as follows: the difference of general power and signal power.Such as calculate the symbol l of sub-frame of uplink 1
General power P (l)all；Then the signal power P (l) of symbol 1 is calculatedsignal, the jamming power for obtaining symbol 1 is I (l)=P
(l)signal-P(l)signal.The jamming power of other 13 symbols in sub-frame of uplink 1 can be determined using identical method.With
This analogizes, so that it is determined that in N number of sub-frame of uplink 14 symbols of each sub-frame of uplink jamming power.
2) average interference power of each symbol in N number of sub-frame of uplink in M symbol is determined.
In obtaining N number of sub-frame of uplink after the jamming power of 14 symbols of each sub-frame of uplink, then each symbol is asked
It is averaged, for example, the jamming power of the symbol 1 of each sub-frame of uplink is added, then divided by N, to obtain symbol 1 in N
Average interference power in a sub-frame of uplink.And so on, to obtain 14 respective average interference powers of symbol.
3) average interference power based on each symbol, determines the jamming power of the sub-frame of uplink of wireless network cell A
Changing rule.
In embodiments of the present invention, the specific implementation of step 3) is as follows:
B1 determines K target jamming power from the M average interference power；Wherein, the K target jamming function
Rate is preceding K of the descending arrangement of M average interference power；Wherein, K is the positive integer less than M；
B2 seeks M-K average interference function in the M average interference power in addition to the K target jamming power
The average value of rate；
B3 obtains the ratio of each the target jamming power and the average value in the K target jamming power, obtains
K ratio；
B4 determines that ratio is more than or equal to P ratio of the first preset threshold from the K ratio；Wherein, P be less than
Positive integer equal to K；
B5 determines P symbol corresponding with the P ratio when P is more than or equal to the second preset threshold；
B6 obtains the changing rule of the jamming power according to difference set, includes described P symbol in the difference set
Number P notation index in every two notation index difference.
Continue to use detection LTE system in wireless network cell A whether be the out-of-sync cells GPS example, management station obtain
After 14 respective average interference powers of symbol, several biggish symbols of jamming power, tool are determined first from 14 symbols
It for body, can be the average interference power of 14 symbols according to being ranked up from big to small, obtain K symbol in the top
Number, K is the numerical value pre-set, such as K=4；It is also possible to preset jamming power threshold value, as long as some symbol is flat
Equal jamming power is greater than the jamming power threshold value, then it is assumed that the jamming power of the symbol is larger, and this is not restricted.It is with K=4
Example, management station obtain 4 biggish symbols of jamming power, respectively symbol 1, symbol 5, symbol 8 and symbol from 14 symbols
Numbers 12.Then, the average interference power of remaining 10 symbols is averaging, obtains Iavg, by symbol 1, symbol 5, symbol 8 with
And the average interference power and I of symbol 12avgIt is divided by, obtains ratio I1/Iavg、I5/Iavg、I8/Iavg、I12/Iavg；This 4 are compared
Value is compared with the first preset threshold, which can be by emulation or to the reality of wireless network cell A
Test obtains, such as can be 9db, if ratio is greater than the first preset threshold, then it is assumed that doubtful downlink interference, and write down and the ratio
It is worth the notation index of corresponding symbol, for example, I1/Iavg、I5/Iavg、I8/IavgRespectively greater than the first preset threshold, then it is assumed that symbol
Number 1, symbol 5 and the interference of the doubtful downlink of symbol 8, record symbol index are 1,5,8.If being judged as the symbol of doubtful downlink interference
Number quantity be greater than the second preset threshold, such as the second preset threshold be 2, since symbol 1, symbol 5 and symbol 8 are judged as
Doubtful downlink interference, 3 > 2, therefore, by the difference between the notation index of symbol 1, symbol 5 and symbol 8, as wireless network
The changing rule of the jamming power of cell A, that is, the difference of the notation index between symbol 1 and symbol 5 is 4, symbol 1 and symbol 8
Between the difference of notation index be 7, the difference of the notation index between symbol 5 and symbol 8 is 3, thus, wireless network cell
The interference power variations rule of A is { 3,4,7 }.
After executing completion step S101, the method in the embodiment of the present invention just executes step S102, it may be assumed that described in determining
The changing rule of jamming power whether the variation with the power pattern of the reference signal of the downlink subframe of the wireless network cell
Rule is identical.
In embodiments of the present invention, the specific implementation of step S102 is as follows:
C1 obtains the Q symbol that performance number in the power pattern of the reference signal is greater than Q symbol of predetermined power value
Index；Wherein, Q is positive integer；
C2 obtains the changing rule of the power pattern of the reference signal, the target difference according to target difference set
The difference of every two notation index in Q notation index in set including the Q symbol；
C3, determine the difference set whether be target collection subset.
Continue to use detection LTE system in wireless network cell A whether be the out-of-sync cells GPS example, when management station determine
After the interference power variations rule of wireless network cell A is { 3,4,7 }, then the downlink subframe for obtaining wireless network cell A is needed
The changing rule of the power pattern of reference signal.With the downlink subframe of LTE system for 2 ports, Physical Downlink Shared Channel/physics
Down control channel (Physical Downlink Shared Channel/Physical Downlink Control
Channel, PDSCH/PDCCH) occupy resource block (Resource Block, RB) less subframe for, then wireless network is small
It is default to determine that performance number is greater than as shown in figure 3, according to the power pattern of the reference signal for the power pattern of the reference signal of area A
Multiple symbols of performance number.The predetermined power value can be fixed value, be also possible to every in the power pattern by reference signal
What the performance number of a symbol obtained after being averaging, this is not restricted.From the figure 3, it may be seen that the downlink subframe reference signal of LTE system
It is higher in the time-domain power of symbol 0,4,7,11, and other symbol powers are lower, so that obtaining notation index is 0,4,7,11, so
Afterwards using the difference between notation index two-by-two as the changing rule of the power pattern of reference signal, that is, symbol 0 and symbol 4 it
Between the difference of notation index be 4, the difference of the notation index between symbol 0 and symbol 7 is 7, between symbol 0 and symbol 11
The difference of notation index is 11, and the difference of the notation index between symbol 4 and symbol 7 is 3, the symbol between symbol 4 and symbol 11
The difference of number index is 3, and the difference of the notation index between symbol 7 and symbol 11 is 4, thus, the power pattern of reference signal
Changing rule be { 3,4,7,11 }.Certainly, the changing rule of the power pattern of the reference signal of downlink subframe needs basis should
The actual disposition situation of wireless network cell A determines, when configuration parameter difference, the power diagram of the reference signal of downlink subframe
The changing rule of sample can occur to change accordingly, herein not to the changing rule of the power pattern of the reference signal of downlink subframe
It is restricted.
Finally, by judge wireless network cell A interference power variations rule gather whether be reference signal function
The mode of the subset of the set of rate pattern changing rule, determine jamming power changing rule whether the power diagram with reference signal
The changing rule of sample is identical.In the subset for the set that the collection of interference power variations rule is combined into power diagram sample changing rule, really
The changing rule for determining jamming power is identical as the changing rule of power pattern；Otherwise, it determines the changing rule and ginseng of jamming power
The changing rule for examining the power pattern of signal is different.
After executing completion step S102, the method in the embodiment of the present invention just executes step S103, it may be assumed that determining
When the changing rule for stating jamming power is identical as the changing rule of power pattern of the reference signal, the wireless network is determined
Cell is the out-of-sync cells GPS.
Above-mentioned example is continued to use, since set { 3,4,7 } is to gather the subset of { 3,4,7,11 }, management station determines nothing
The power pattern of the reference signal of the changing rule and cell downlink subframe of the jamming power of the sub-frame of uplink of line network cell A
Changing rule it is identical, so that it is determined that wireless network cell A be the out-of-sync cells GPS.
Method after executing completion step S103, in the embodiment of the present invention further include:
The wireless network cell is reported to the management equipment of the wireless communication system.
Continue to use detection LTE system in wireless network cell A whether be the out-of-sync cells GPS example, determining wireless network
Network cell A be the out-of-sync cells GPS after, then the cell ID of wireless network cell A or community configured information etc. are reported into pipe
Reason station releases interference so that management station can in time be adjusted wireless network cell A.
As it can be seen that in technical solution provided in an embodiment of the present invention, by the interference function for determining the wireless network cell
The changing rule of rate, then by the downlink of the changing rule of the jamming power for the sub-frame of uplink determined and the wireless network cell
The changing rule of the power pattern of the reference signal of subframe is compared, using the drawing feature of the reference signal of downlink subframe,
