The embodiment of the present invention provides a kind of method detecting interference and network equipment, and wherein, network equipment determines interference level threshold value, and determines that the frequency of community is by strong jamming according to the wireless measurement report of the subdistrict frequency point obtained within N number of time period.In the method, wireless measurement report according to measuring in real time determines interference, it is possible to accurately determines strong jamming, and reports by obtaining the wireless measurement of N number of time period, the measured value avoiding acquisition of single time period measurement report is unstable, causes the interference level determined unstable.
nullThe communication standard of the mobile communication system that embodiments of the invention are suitable for includes but not limited to: global system for mobile communications (GlobalSystemofMobilecommunication，GSM)、CDMA (CodeDivisionMultipleAccess，CDMA) IS-95、CDMA (CodeDivisionMultipleAccess，CDMA) 2000、TD SDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess，TD-SCDMA)、WCDMA (WidebandCodeDivisionMultipleAccess，WCDMA)、Time division duplex-Long Term Evolution (TimeDivisionDuplexing-LongTermEvolution，TDDLTE)、FDD-Long Term Evolution (FrequencyDivisionDuplexing-LongTermEvolution，FDDLTE)、Long Term Evolution-enhancing (LongTermEvolution-Advanced，LTE-advanced)、Personal handyphone system (PersonalHandy-phoneSystem，PHS) etc..
The embodiment of the present invention is applicable not only to TD-SCDMAFemto system, applies also for other (such as: GSM, WCDMA, LTE) Femto systems, and other mobile communication system in addition to Femto.
The schematic diagram of the procedure of the detection interference that Fig. 1 provides for the embodiment of the present invention, as it is shown in figure 1, the method comprises the following steps:
S101: network equipment determines interference level threshold value；
S102: for a frequency of a community, when in network equipment each time period in N number of time period, the interference level value of this frequency is more than interference level threshold value, determine that this frequency is by strong jamming, wherein, the interference level value of this frequency within each time period is that network equipment determines according to the wireless measurement report of this frequency obtained in this time period, and N is not less than 2.
Here, network equipment can be base station, base station controller, operation maintenance center etc..Usually, in mobile communication system, a base station includes one or more community, and each community can use one or more frequency simultaneously.The method of the detection interference that the embodiment of the present invention provides is that each frequency for community is implemented respectively, i.e. when a base station includes multiple community, and a community uses multiple frequency simultaneously, each frequency of each community is detected interference respectively.
Wherein, N number of time period can be the time period continuous in time, it is also possible to being the time period being interrupted, the length of N number of time period can be equal, it is also possible to, depending on implementing.
Wherein, network equipment can be at the end of each time period, determine that whether the interference level value of this time period this frequency interior is more than interference level threshold value, it is also possible at the end of N number of time period is all, determine whether the interference level value of this frequency in each time period is more than interference level threshold value respectively.
Preferably, interference level threshold value is jamming report number accounting；
Network equipment determines the interference level value of this frequency in this time period according to the wireless measurement report of this frequency obtained in the time period particularly as follows: network equipment determines that the ratio of the wireless measurement report total that the channel quality value obtained within this time period obtains in accounting for this time period less than the wireless measurement number of reports of the channel quality thresholds preset is the interference level value of this frequency in this time period.
Wherein, interference level threshold value is not limited to jamming report number accounting.Such as, when the measurement item of wireless measurement report is signal-to-noise ratio (SignaltoInterferenceRatio, SIR) time, the threshold value (such as :-3dB) of the opposite number of a SIR can be set as interference level threshold value, take the opposite number of meansigma methods of each measured value SIR in the wireless measurement report of this frequency as interference level value, when the opposite number of the meansigma methods of this SIR is more than-3dB, determine that this frequency is by strong jamming.
When interference level threshold value is jamming report number accounting, the measured value during network equipment is reported according to wireless measurement determines that the channel quality value that the wireless measurement of correspondence is reported is less than the channel quality threshold values preset.
Measurement item in wireless measurement report can include but not limited to: SIR, interference signal intensity are (for TD-SCDMA system, can be slot interfering signal of time code power (TimeslotInterferenceSignalCodePower, ISCP)), data error rate is (for TD-SCDMA system, can be transmission channel Block Error Rate (transportchannelBLockErrorRate, BLER)), the bit error rate (for TD-SCDMA system, can be transmission channel bit error rate (TransportchannelBitErrorRate)).
Such as, for measuring item SIR, the channel quality value measured value equal to SIR can be set.Can set, according to implementing, the channel quality thresholds preset, such as: 8dB, actual value is not limited to 8dB, it is only for example.In the wireless measurement report of the SIR obtained in then network equipment determines this time period, the ratio of total SIR wireless measurement number of reports that the sir measurement value wireless measurement number of reports less than 8dB obtains in accounting for this time period, for the interference level value of this frequency in this time period.
For another example, for measuring item time slot ISCP, due to the measurement of this measurement item is the intensity disturbing signal, and for identical available signal power, interference signal is the strongest, and channel quality is the poorest.Therefore, the opposite number of the meansigma methods that can set each time slot ISCP measured value is not limited to take opposite number as channel quality value, actual establishing method, as long as it is the strongest to embody interference signal, channel quality is the poorest.Such as, set the channel quality value opposite number equal to the meansigma methods of each time slot ISCP measured value, set the channel quality thresholds preset, such as: 50dbm.In the wireless measurement report of the time slot ISCP obtained in then network equipment determines this time period, the ratio of total time slot ISCP wireless measurement number of reports that the opposite number of the meansigma methods of each time slot ISCP measured value wireless measurement number of reports less than 50dbm obtains in accounting for this time period, for the interference level value of this frequency in this time period.
For other measurement item, method is similar to, repeats the most one by one.
Preferably, network equipment obtains the wireless measurement report of this frequency in each time period in N number of time period, including: network equipment is within each time period of N number of time period, and the cycle obtains the wireless measurement report of this frequency.
Preferably, in adjacent two time periods of N number of time period, if the wireless measurement report according to this frequency obtained in the previous time period determines that the interference level value of this frequency more than interference level threshold value, then obtains the cycle of wireless measurement report less than the cycle obtaining the report of described wireless measurement in the previous time period in the later time period.
Such as at the end of a time period, it is judged that in this time period, whether the interference level value of this frequency is more than interference level threshold value, if it is greater, then obtain the cycle of wireless measurement report in shortening the next time period；Otherwise, the cycle of wireless measurement report is obtained in not shortening the next time period.
When wireless measurement is reported as the wireless measurement report that user terminal reports, network equipment can control message by wave point to user terminal sending measuring, message is carried the report cycle of setting, change the report cycle that user terminal reports wireless measurement to report, in order to network equipment obtains wireless measurement report with this report cycle.
When wireless measurement is reported as the wireless measurement report that base station reports, the mode changing the report cycle that base station reports wireless measurement to report has multiple, includes but not limited to following two ways:
Mode one, network equipment are base station self, then base station self determines the cycle obtaining wireless measurement report；
Mode two, network equipment are radio network controller (RadioNetworkController, or operation maintenance center (OperationandMaintenanceCenter RNC), OMC) contour level equipment, then can be by the interface between this high-level device and base station, sending measuring control command or message, wherein carry the report cycle of setting so that base station reports wireless measurement to report according to the report cycle set, in order to network equipment obtains wireless measurement report with this report cycle.
If the wireless measurement report according to this frequency obtained in the previous time period determines that the interference level value of this frequency is more than interference level threshold value, then this frequency of preliminary judgement receives strong jamming.In order to more accurately determine this frequency further by strong jamming, then within the ensuing time period, wireless measurement report is obtained with the less cycle, so, network equipment can obtain the report of more wireless measurement within the time period of predetermined length, more accurate to wireless measurement report result, more can reflect the interference level of this frequency current.Can effectively eliminate the inaccurate situation of determination interference level that bursty interference causes.
Preferably, if network equipment is high-level device, wireless measurement is reported as the wireless measurement that wireless measurement is reported or base station the reports report that user terminal reports；If network equipment is base station, wireless measurement is reported as the wireless measurement that wireless measurement is reported or base station self the determines report that user terminal reports.
Here, high-level device may include but be not limited to radio network controller (RadioNetworkController, RNC), operation maintenance center (Operation&MaintenanceCenter, OMC), femto gateway (HomeNodeBGateway, HB-GW) etc..When network equipment is high-level device, base station or user terminal report wireless measurement to report to network equipment；When network equipment is base station, wireless measurement report can be the wireless measurement report that user terminal reports, it is also possible to be that the wireless measurement that base station self determines is reported.
Preferably, network equipment determines that this frequency, by after strong jamming, stops community and uses this frequency.
Cause in order to avoid use receives strongly disturbing frequency quality of service to decline (such as: cutting off rate rising, access failure rate reduction etc.), alternatively, the use of this frequency can be stopped；Or, it is possible to reducing the priority of this frequency, such as, when community uses multiple frequency, other are disturbed less frequency can to make user terminal priority access, and when the resource of these frequencies all takes, then access should be by strongly disturbing frequency；Again or, it is possible to further determine that and this frequency caused strongly disturbing community, reduce interference by inter-cell coordination (such as, allowing other that this frequency of current area is caused strongly disturbing cell change frequency).Adoptable means are not limited to above citing, can be determined on a case-by-case basis.
Preferably, network equipment determines that this frequency by after strong jamming, according to the wireless measurement report of the received signal strength of each adjacent cell of this community obtained, determines the jamming performance value of each frequency in the available frequency point list of community；
It is one or more that configuration community uses in the frequency that jamming performance value in this available frequency point list is minimum.
After network equipment determines that this frequency is by strong jamming, it may be determined that a new frequency, and configure this community and use this new frequency.Usually, operator is when the network planning, and meeting the whole network unified planning, possible some community of appointment is only capable of using a limited number of frequency, to avoid other communities of surrounding are interfered or disturbed by other communities.Therefore, when network equipment determines new frequency, need to select in the available frequency point list of this community.If the spendable frequency in community does not limit, the available frequency point list of community can be all available frequencies in mobile communication system.Alternatively, this new frequency can be determined according to frequency by the disturbed condition of other communities of surrounding.Specifically, can be according to the received signal strength of each adjacent cell of this community obtained (for TD-SCDMA system, can be adjacent cell Primary Common Control Physical Channel received signal code power (PrimaryCommonControlPhysicalChannelReceivedSignalCodePow er, PCCPCHRSCP) wireless measurement report, determine the jamming performance value (this jamming performance value is for weighing the interference level of other communities of surrounding that this frequency may be subject to) of frequency, finally determine that the minimum frequency of jamming performance value is new frequency, and configure community and use this frequency.The frequency minimum due to jamming performance value may have multiple, it may be determined that one or more is configured to new frequency.
Preferably, the jamming performance value of each frequency during network equipment determines the available frequency point list of community according to the following step:
For each frequency in the available frequency point list of community, network equipment judges whether the wireless measurement report comprising the adjacent cell frequency with the frequency point co-frequency in this available frequency point list, if not, it is determined that in this available frequency point list, the jamming performance value of this frequency is default least interference performance number；If, it is determined that the jamming performance value that meansigma methods is this frequency of the received signal strength value in the wireless measurement report of each adjacent cell received signal strength of the adjacent cell value of frequency point in the wireless measurement report of the adjacent cell received signal strength of acquisition and this frequency point co-frequency in this available frequency point list.
The measured value reported in being reported by wireless measurement determines each frequency experienced interference level, and result is more accurate.
Below, the method determining jamming performance value is illustrated by following two.
Example one,
The available frequency point list of community includes 3 frequencies: 2011.2MHz, 2012.8MHz, 2014.4MHz, in the wireless measurement report of the received signal strength of each adjacent cell that network equipment obtains, the wireless measurement not having frequency 2011.2MHz is reported, then can determine that the jamming performance value of 2011.2MHz is default least interference performance number.
Example two,
The available frequency point list of community still includes 3 frequencies: 2011.2MHz, 2012.8MHz, 2014.4MHz, network equipment obtains the wireless measurement report of the received signal strength of 100 each adjacent cells, wherein, frequency in 10 wireless measurement reports is 2011.2MHz, and the meansigma methods of the adjacent cell received signal strength reported in these 10 wireless measurement reports is-103dBm；Frequency in 15 wireless measurement reports is 2012.8MHz, and the meansigma methods of the adjacent cell received signal strength reported in these 15 wireless measurement reports is-113dbm；Frequency in 18 wireless measurement reports is 2014.4MHz, and the meansigma methods of the adjacent cell received signal strength reported in these 18 wireless measurement reports is-95dbm.Then the jamming performance value of frequency 2012.8MHz is minimum.
Preferably, the report of the wireless measurement of each adjacent cell received signal strength be network equipment after determining that this frequency is by strong jamming, or obtain within any one or more time periods obtaining N number of time period of wireless measurement report of this frequency.
Below, the interference detection method of the present invention is illustrated by two embodiments.Wherein, embodiment one gives detection interference and the example of configuration frequency process of the present invention；Embodiment two gives the example of the configuration frequency concrete grammar of the present invention.
Embodiment one
In embodiment one, network equipment is Femto base station, and wireless measurement is reported as the wireless measurement report that user terminal reports, and the Femto base station cycle obtains wireless measurement report, and the time period number obtaining wireless measurement report is 2(i.e. N=2).
Fig. 2 is detection interference and the flow chart of configuration frequency process of the embodiment of the present invention one.As in figure 2 it is shown, the step of the detection interference of Femto base station and configuration frequency is as follows:
S201:Femto base station determines interference level threshold value；
S202: the frequency used for a community, Femto base station obtains the wireless measurement report of this frequency in first time period T1, and in T1, the report cycle of wireless measurement report is IntervalA；
The wireless measurement report of this frequency that S203:Femto base station obtains according to step S202, judge that whether the interference level value of this frequency is more than interference level threshold value, if, then primarily determine that this frequency is by strong jamming, the normal work of Femto base station may be affected, perform step S204, if it is not, flow process terminates；
S204: the report cycle that user terminal UE reports wireless measurement to report is shortened to InvervalB, wherein, IntervalB is less than IntervalA；
S205:Femto base station obtains the wireless measurement report of this frequency in the second time period T2；
S206:Femto base station is reported according to the wireless measurement of this frequency obtained in step S205, it is judged that whether the interference level value of this frequency is more than interference level threshold value, if, then determine that this frequency, by strong jamming, has affected the normal work of Femto base station, performed step S207, if it is not, flow process terminates；
S207:Femto base station optimizes frequency configuration.
In step S203, if the interference level value that Femto base station judges this frequency is not more than interference level threshold value, or in step S206, if Femto base station judges when the interference level value of this frequency is not more than interference level threshold value, then Femto base station determines that this frequency experienced interference level is within normal range, need not optimize frequency configuration further, flow process terminates.
In S207 step, Femto base station optimizes frequency configuration and comprises the steps that Femto base station stops step S201 and used by strongly disturbing frequency to determined by step S206, and/or Femto base station determines the new less frequency that is interfered, and configure the new frequency that community uses this to determine.
Alternatively, Femto base station execution capable of circulation said process, to detect each frequency experienced interference of its community in real time.Such as, during shown in Fig. 2, when the result that step S203 or step S206 perform be " no " and time, process terminates, and then can return to step S201 repeated execution of steps S201 to step S207；For another example, when the execution result of step S206 is " be " time, then perform step S207, Femto base station is optimized frequency configuration.Afterwards, can return to step S201, repeated execution of steps S201 is to step S207, and so forth, it is achieved the Interference Detection of each frequency of community each to Femto base station and optimization frequency configuration.
Alternatively, the cycle period T that Femto base station can also be preset repeats said process, and wherein, T should meet more than or equal to T1 Yu T2 sum.For the setting of the length of T, can be according to wireless environment around Femto base station depending on, when around wireless environment variation is frequent, can the value of T be arranged less, it is simple to the change of wireless environment around is quickly reflected by base station.When around wireless environment variation is slow, the value of T can be arranged relatively big, to reduce the process load of Femto base station.In the case of pre-setting T, T1 and T2 also to be arranged according to the size of T, needs to meet T1's Yu T2 and no more than T.
Setting for T1 and T2, also dependent on depending on the implementing of system, when the value that T1 and T2 is arranged is bigger, Femto base station can receive the wireless measurement report that user terminal reports within the longer time, in order to knows the more stable interference level being subject to of detected frequency.Alternatively, T2 may be configured as compared with T1 less, it is simple to interference is processed by Femto base station as early as possible.
When Femto base station includes multiple community, and each community uses multiple frequency, the above-mentioned Interference Detection process of each frequency of each community of Femto base station can independently be carried out.
Alternatively, T, T1, T2 are the integral multiple of Transmission Time Interval (TransmissionTimeInterval, TTI).
Wherein, the interference level threshold value determined in step s 201, interference when normally can work according to frequency is born the upper limit and is arranged.
Wherein, it is set smaller than IntervalA by the report cycle IntervalB reported by wireless measurement, make primarily determining that frequency may be by the case of strongly disturbing, shorten the report cycle of wireless measurement report, Femto base station can obtain the wireless measurement report that more UE reports in the second time period T2, to obtain interference detection results more accurately, effectively eliminate the random case arrived due to the shorter Interference Detection caused of the set of time of T2, avoid optimizing frequency configuration continually, affect carrying out of Femto base station regular traffic；If circulation performs said process, then the report cycle that after this frequency Interference Detection terminates, can recover wireless measurement report is IntervalA, reduces Femto base station and the signaling consumption of UE, and reduces the processing load of Femto base station.
In step S202 and S204, UE is reported the setting of the report cycle that wireless measurement reports, message can be controlled by Femto base station sending measuring and realize.
Femto base station can allow UE with the Femto base station desired cycle, periodically report wireless measurement to report with sending measuring control message to the UE in community, and comprise the measured value of required reflection channel quality in wireless measurement is reported.
Specifically, the Reportinginterval controlled in message that measures by issuing arranges the report cycle of wireless measurement report.
Above, by embodiment one specifically illustrate network equipment determine frequency by strongly disturbing process, below, by embodiment two to network equipment optimize frequency configuration process be illustrated.
Embodiment two,
As it is shown on figure 3, the process optimizing frequency configuration of embodiment two includes:
In embodiment two, the wireless measurement being optimized frequency configuration institute foundation is reported as: the wireless measurement report (wireless measurement report includes: the frequency configuration information of adjacent cell and the received signal strength of adjacent cell) of the received signal strength of each adjacent cell that UE reports in this community obtained in the last first time period T1 that Femto base station obtains and the second time period T2.Wherein, there is strongly disturbing community in the frequency that this community determines in being embodiment one.
S301:Femto base station obtains in the last T1+T2 time period, the wireless measurement report of the received signal strength of each adjacent cell that UE reports in this community；
S302:Femto base station, according to the wireless measurement report of this community obtained in step S301, determines the jamming performance value of each frequency in this community available frequency point list；
S303:Femto base station configures this community and uses one or more frequencies of jamming performance value minimum.
Femto base station sending measuring controls message to UE so that UE periodically reports the wireless measurement of adjacent cell received signal strength to report, in the wireless measurement report reported, not only includes adjacent cell received signal strength value, also includes the frequency configuration information of adjacent cell.
In step s 302, according to the wireless measurement report obtained in step S301, if calculating Femto base station to use certain frequency in available frequency point list, when adjacent cell uses the frequency identical with this frequency, under current wireless environment, this community experienced interference level value, i.e. equal to the jamming performance value of this frequency.
Alternatively, following method can be used to determine the jamming performance value of frequency.For each frequency in the available frequency point list of this community, Femto base station judges whether the wireless measurement report comprising the adjacent cell frequency with the frequency point co-frequency in this available frequency point list, if not, it is determined that in this available frequency point list, the jamming performance value of this frequency is default least interference performance number；If, it is determined that the jamming performance value that meansigma methods is this frequency of the received signal strength value in the wireless measurement report of each adjacent cell received signal strength of the adjacent cell value of frequency point in the wireless measurement report of the adjacent cell received signal strength of acquisition and this frequency point co-frequency in this available frequency point list.
If the frequency of jamming performance value minimum exists multiple, then randomly select one or more.The number choosing frequency can be the frequency number that Femto base station needs configuration.
Using the method optimizing frequency configuration in embodiment two, Femto base station, when determining frequency by strong jamming, optimizes frequency configuration, reduces interference, it is ensured that it normally works.The wireless measurement report periodically reported by UE, only need to increase respective handling in Femto base station side, it is achieved difficulty is low.
Based on same inventive concept, the embodiment of the present invention additionally provides a kind of network equipment detecting interference, the method detecting interference provided to the embodiment of the present invention due to the principle of this network equipment solution problem is similar, therefore the enforcement of this network equipment may refer to the enforcement of method, repeats no more in place of repetition.
