The 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 (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) IS-95, code division multiple access (Code Division Multiple Access, CDMA) 2000, TD SDMA (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, WCDMA), time division duplex-Long Term Evolution (Time Division Duplexing-Long Term Evolution, TDD LTE), Frequency Division Duplexing (FDD)-Long Term Evolution (Frequency Division Duplexing-Long Term Evolution, FDD LTE), Long Term Evolution-enhancing (Long Term Evolution-Advanced, LTE-advanced), personal handyphone system (Personal Handy-phone System, PHS) etc.
The embodiment of the invention is not only applicable to TD-SCDMA Femto system, also is applicable to other (such as GSM, WCDMA, LTE) Femto systems, and other mobile communication system except Femto.
The schematic diagram of the procedure that the detection that Fig. 1 provides for the embodiment of the invention is disturbed, as shown in Figure 1, this method may further comprise the steps:
S101: network equipment is determined the interference level threshold value;
S102: at a frequency of a residential quarter, the interference level value of network equipment this frequency in each time period in N time period is during greater than the interference level threshold value, determine that this frequency is subjected to strong jamming, wherein, the interference level value of this frequency in each time period is that network equipment determines that according to the wireless measurement report of this frequency that obtains in this time period 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 comprises one or more residential quarters, and each residential quarter can be used one or more frequencies simultaneously.The method that detection that the embodiment of the invention provides is disturbed is to implement respectively at each frequency of residential quarter,, when a base station comprises a plurality of residential quarters, when residential quarter is used a plurality of frequency simultaneously, each frequency of each residential quarter is detected interference respectively that is.
Wherein, N time period can be the time period continuous in time, also can be the time period of being interrupted, and the length of N time period can equate, also can not wait, and decides on specific implementation.
Wherein, network equipment can be when each time period finishes, whether determine the interference level value of this frequency in this time period greater than the interference level threshold value, also can when N time period all finishes, determine that respectively whether the interference level value of this frequency in each time period is greater than the interference level threshold value.
Preferably, the interference level threshold value is that jamming report is counted accounting;
Network equipment according to the wireless measurement of this frequency that obtains in the time period report determine that the interference level value of this frequency in this time period is specially: network equipment determines that wireless measurement number of reports that the channel quality value of obtaining is lower than default channel quality thresholds accounts for the ratio of the wireless measurement report sum that obtains in this time period and is the interference level value of this frequency in this time period in this time period.
Wherein, the interference level threshold value is not limited to jamming report and counts accounting.Such as, the measurement item of reporting when wireless measurement is signal-to-jamming ratio (Signal to Interference Ratio, SIR) time, can set the opposite number of a SIR threshold value (such as :-3dB) as the interference level threshold value, get the opposite number of mean value of each the measured value SIR in the wireless measurement report of this frequency as the interference level value, when the opposite number of the mean value of this SIR during greater than-3dB, determine that this frequency is subjected to strong jamming.
When the interference level threshold value is jamming report when counting accounting, network equipment determines that according to the measured value in the wireless measurement report channel quality value of corresponding wireless measurement report is lower than default channel quality threshold values.
Measurement item in the wireless measurement report can include but not limited to: SIR, interference signal intensity are (for the TD-SCDMA system, can be slot interfering signal of time sign indicating number power (Timeslot Interference Signal Code Power, ISCP)), data error rate is (for the TD-SCDMA system, can be transmission channel Block Error Rate (transport channel BLock Error Rate, BLER)), the error rate (for the TD-SCDMA system, can be transmission channel bit error rate (Transport channel Bit Error Rate)).
Such as, for measuring a SIR, can set the measured value that channel quality value equals SIR.Can set default channel quality thresholds according to specific implementation, such as: 8dB, actual value is not limited to 8dB, only is example here.Then network equipment is determined in the wireless measurement report of the SIR that obtains in this time period, the sir measurement value accounts for the ratio of the total SIR wireless measurement number of reports that obtains in this time period less than the wireless measurement number of reports of 8dB, is the interference level value of this frequency in this time period.
For another example, for measuring a time slot ISCP, because this measurement measurement is the intensity of interference signal, for identical available signal power, interference signal is more strong, and channel quality is more poor.Therefore, the opposite number that can set the mean value of each time slot ISCP measured value is channel quality value, and actual establishing method is not limited to get opposite number, as long as it is more strong to embody interference signal, channel quality is poor getting final product more.Such as, set the opposite number that channel quality value equals the mean value of each time slot ISCP measured value, set default channel quality thresholds, such as: 50dbm.Then network equipment is determined in the wireless measurement report of the time slot ISCP that obtains in this time period, the opposite number of the mean value of each time slot ISCP measured value accounts for the ratio of the total time slot ISCP wireless measurement number of reports that obtains in this time period less than the wireless measurement number of reports of 50dbm, is the interference level value of this frequency in this time period.
For other measurement item, method is similar, gives unnecessary details no longer one by one here.
Preferably, network equipment obtains the wireless measurement report of this frequency in each time period in N time period, comprising: network equipment is in each time period of N time period, and the cycle is obtained the wireless measurement report of this frequency.
Preferably, in adjacent two time periods of N time period, if the interference level value of determining this frequency according to the wireless measurement report of this frequency that obtains in the previous time period, is then obtained the cycle of wireless measurement report greater than the interference level threshold value less than the cycle of obtaining described wireless measurement report in the previous time period in the back time period.
Such as when a time period finishes, whether judge the interference level value of this frequency in this time period greater than the interference level threshold value, if greater than, then shorten the cycle of obtaining the wireless measurement report in the next time period; Otherwise, do not shorten the cycle of obtaining the wireless measurement report in the next time period.
When wireless measurement is reported as the wireless measurement report of user terminal to send up, network equipment can be by wave point to user terminal sending measuring control message, carry the report cycle of setting in the message, change the report cycle of user terminal to send up wireless measurement report, so that network equipment obtains the wireless measurement report with this report cycle.
When wireless measurement was reported as the wireless measurement report that the base station reports, changing mode that the base station reports the report cycle of wireless measurement report had multiplely, includes but not limited to following dual mode:
Mode one, network equipment are base station self, and then the cycle of wireless measurement report is determined to obtain in base station self;
Mode two, network equipment are radio network controller (Radio Network Controller, RNC) or (the Operation and Maintenance Center of operation maintenance center, OMC) contour level equipment, then can be by the interface between this high-level device and the base station, sending measuring control command or message, wherein carry the report cycle of setting, make the base station report the wireless measurement report according to the report cycle of setting, so that network equipment obtains the wireless measurement report with this report cycle.
If the interference level value of determining this frequency according to the wireless measurement report of this frequency that obtains in the previous time period is greater than the interference level threshold value, then this frequency of preliminary judgement has been subjected to strong jamming.In order to determine more accurately that further this frequency is subjected to strong jamming, then in the ensuing time period, obtain wireless measurement report with the littler cycle, like this, network equipment can obtain more wireless measurement report in the time period of predetermined length, report that to wireless measurement result is more accurate, more can reflect the interference level of current this frequency.Can effectively eliminate the inaccurate situation of definite interference level that bursty interference causes.
Preferably, if network equipment is high-level device, wireless measurement is reported as the wireless measurement report of user terminal to send up or the wireless measurement report that the base station reports; If network equipment is the base station, wireless measurement is reported as the wireless measurement report of user terminal to send up or the wireless measurement report that base station self is determined.
Here, high-level device can include but not limited to radio network controller (Radio Network Controller, RNC), (Operation﹠amp of operation maintenance center; Maintenance Center, OMC), femto gateway (Home NodeB Gateway, HB-GW) etc.When network equipment was high-level device, base station or user terminal reported the wireless measurement report to network equipment; When network equipment was the base station, the wireless measurement report can be the wireless measurement report of user terminal to send up, also can be the wireless measurement report that base station self is determined.
Preferably, network equipment determines that this frequency is subjected to after the strong jamming, stops the residential quarter and uses this frequency.
Be subjected to strongly disturbing frequency and caused quality of service to descend (such as cutting off rate rising, the reduction of access failure rate etc.) for fear of use, alternatively, can stop the use of this frequency; Perhaps, also can reduce the priority of this frequency, such as, when a plurality of frequency is used in the residential quarter, can make user terminal preferentially insert the less frequency of other suffered interference, when the resource of these frequencies all takes, insert this again and be subjected to strongly disturbing frequency; Again or, also can further determine this frequency is caused strongly disturbing residential quarter, by the minizone coordinate (such as, allow other these frequencies to current area cause strongly disturbing residential quarter to change frequency) reduce interference.Adoptable means are not limited to above giving an example, and can be determined on a case-by-case basis.
Preferably, network equipment determines that this frequency is subjected to after the strong jamming, according to the wireless measurement report of the reception signal strength signal intensity of each adjacent residential quarter of this residential quarter that obtains, determines the jamming performance value of each frequency in the available frequency tabulation of residential quarter;
Allocating cell uses one or more in the frequency of jamming performance value minimum in this available frequency tabulation.
After network equipment determines that this frequency is subjected to strong jamming, can determine a new frequency, and dispose this residential quarter and use this new frequency.Usually, operator when the network planning, can the whole network unified planning, may specify some residential quarter only can use limited several frequencies, with avoid to around other residential quarters cause the interference of disturbing or being subjected to other residential quarters.Therefore, when network equipment is determined new frequency, need in the available frequency tabulation of this residential quarter, select.If the spendable frequency in residential quarter without limits, the available frequency tabulation of residential quarter can be all available frequencies in the mobile communication system.Alternatively, can be subjected to according to frequency around the disturbed condition of other residential quarters determine this new frequency.Particularly, can be according to the reception signal strength signal intensity of each adjacent residential quarter of this residential quarter that obtains (for the TD-SCDMA system, can be adjacent residential quarter Primary Common Control Physical Channel received signal code power (Primary Common Control Physical Channel Received Signal Code Power, PCCPCH RSCP) wireless measurement report, determine the jamming performance value (this jamming performance value is used for weighing the interference level of other residential quarters on every side that this frequency may be subjected to) of frequency, the frequency of final definite jamming performance value minimum is new frequency, and allocating cell uses this frequency.Because it is a plurality of that the frequency of jamming performance value minimum may have, and can determine that one or more is configured to new frequency.
Preferably, network equipment is determined the jamming performance value of each frequency in the available frequency tabulation of residential quarter according to the following step:
At each frequency in the available frequency tabulation of residential quarter, network equipment judge whether to exist comprise with this available frequency tabulation in the wireless measurement report of adjacent subdistrict frequency point of frequency point co-frequency, if not, then determine the least interference performance number of jamming performance value for presetting of this frequency in this available frequency tabulation; If the mean value that the adjacent residential quarter of then determining to obtain receives the reception signal strength values in the wireless measurement report that adjacent subdistrict frequency point value and each adjacent residential quarter of this frequency point co-frequency in should available frequency tabulation in the wireless measurement report of signal strength signal intensity receive signal strength signal intensity is the jamming performance value of this frequency.
Determine the interference level that each frequency is subjected to by the measured value that reports in the wireless measurement report, the result is more accurate.
Below, by the method for the definite jamming performance value of following two examples explanation.
Example one,
Comprise 3 frequency: 2011.2MHz, 2012.8MHz, 2014.4MHz in the available frequency tabulation of residential quarter, in the wireless measurement report of the reception signal strength signal intensity of each adjacent residential quarter that network equipment obtains, do not have the wireless measurement report of frequency 2011.2MHz, can determine that then the jamming performance value of 2011.2MHz is default least interference performance number.
Example two,
Still comprise 3 frequency: 2011.2MHz, 2012.8MHz, 2014.4MHz in the available frequency tabulation of residential quarter, network equipment has obtained the wireless measurement report of the reception signal strength signal intensity of 100 each adjacent residential quarters, wherein, frequency during 10 wireless measurements are reported is 2011.2MHz, and the mean value that the adjacent residential quarter that reports in these 10 wireless measurements reports receives signal strength signal intensity is-103dBm; Frequency during 15 wireless measurements are reported is 2012.8MHz, and the mean value that the adjacent residential quarter that reports in these 15 wireless measurements reports receives signal strength signal intensity is-113dbm; Frequency during 18 wireless measurements are reported is 2014.4MHz, and the mean value that the adjacent residential quarter that reports in these 18 wireless measurements reports receives signal strength signal intensity is-95dbm.The jamming performance value minimum of frequency 2012.8MHz then.
Preferably, the wireless measurement report that each adjacent residential quarter receives signal strength signal intensity be network equipment after definite this frequency is subjected to strong jamming, or in any one or a plurality of time period of N time period that the wireless measurement that obtains this frequency is reported, obtain.
Below, specify interference detection method of the present invention by two embodiment.Wherein, embodiment one has provided the example that frequency process was disturbed and disposed in detection of the present invention; Embodiment two has provided the example of configuration frequency concrete grammar of the present invention.
Embodiment one
In embodiment one, network equipment is the Femto base station, and wireless measurement is reported as the wireless measurement report of user terminal to send up, and the Femto base station cycle is obtained the wireless measurement report, and the time period number of obtaining the wireless measurement report is that 2(is N=2).
Fig. 2 is the flow chart that frequency process was disturbed and disposed in the detection of the embodiment of the invention one.As shown in Figure 2, the step of Femto base station detection interference and configuration frequency is as follows:
S201:Femto determines the base station interference level threshold value;
S202: at the frequency that use a residential quarter, the Femto base station obtains the wireless measurement report of this frequency in very first time section T1, and in T1, the report cycle of wireless measurement report is Interval A;
Report according to the wireless measurement of this frequency that step S202 obtains the S203:Femto base station, judge that whether the interference level value of this frequency is greater than the interference level threshold value, if, determine tentatively that then this frequency is subjected to strong jamming, may influence the operate as normal of Femto base station, execution in step S204, if not, flow process finishes;
S204: report the report cycle of wireless measurement report to shorten to Inverval B user terminal UE, wherein, Interval B is less than Interval A;
The S205:Femto base station obtains the wireless measurement report of this frequency in the second time period T2;
The S206:Femto base station is according to the wireless measurement report of this frequency that obtains at step S205, judge that whether the interference level value of this frequency is greater than the interference level threshold value, if, determine that then this frequency is subjected to strong jamming, influenced the operate as normal of Femto base station, execution in step S207, if not, flow process finishes;
The frequency configuration is optimized in the S207:Femto base station.
In step S203, if the Femto base station judges that the interference level value of this frequency is not more than the interference level threshold value, perhaps in step S206, if the Femto base station is judged when the interference level value of this frequency is not more than the interference level threshold value, then the Femto base station determines that interference level that this frequency is subjected to is in normal range (NR), do not need to be optimized the frequency configuration, flow process finishes.
In the S207 step, the Femto base station is optimized the frequency configuration and can be comprised: the Femto base station stops step S201 to the determined use that is subjected to strongly disturbing frequency of step S206, and/or the Femto base station determines the new less frequency that is interfered, and the allocating cell new frequency that uses this to determine.
Alternatively, Femto base station execution said process capable of circulation, the interference that is subjected to each frequency of its residential quarter of real-time detection.Such as, in process shown in Figure 2, the result who carries out as step S203 or step S206 be " deny " and the time, the process end can be returned step S201 repeated execution of steps S201 then to step S207; For another example, when the execution result of step S206 for " be " and the time, then execution in step S207 optimizes the frequency configuration to the Femto base station.Afterwards, can return step S201, repeated execution of steps S201 and so forth, realizes Interference Detection and the configuration of optimization frequency to each frequency of each residential quarter, Femto base station to step S207.
Alternatively, the cycle period T that the Femto base station also can be preset repeats said process, and wherein, T should satisfy more than or equal to T1 and T2 sum.For the setting of the length of T, can decide according to wireless environment around the Femto base station, when wireless environment variation is frequent, the value of T can be arranged lessly on every side, be convenient to the base station variation of wireless environment is on every side reflected fast.When wireless environment variation is slow on every side, can the value setting of T is bigger, to reduce the processing load of Femto base station.Under the situation that has set in advance T, T1 and T2 also will arrange according to the size of T, need satisfy T1 and T2 and be not more than T.
Setting for T1 and T2, also can decide according to the specific implementation of system, when the value that arranges as T1 and T2 was big, the Femto base station can receive the wireless measurement report of user terminal to send up in the longer time, in order to know the more stable interference level that is subjected to that is detected frequency.Alternatively, T2 can be set to compare with T1 less, is convenient to the Femto base station and as early as possible interference is handled.
When the Femto base station comprises a plurality of residential quarters, when a plurality of frequency is used in each residential quarter, can independently carry out the above-mentioned Interference Detection process of each frequency of each residential quarter of Femto base station.
Alternatively, T, T1, T2 are Transmission Time Interval (Transmission Time Interval, integral multiple TTI).
Wherein, the interference level threshold value of in step S201, determining, upper limit setting is born in the interference in the time of can be according to the frequency operate as normal.
Wherein, report cycle Interval B by the wireless measurement report is set to the A less than Interval, make and determine that preliminary frequency may be subjected under the strongly disturbing situation, shorten the report cycle of wireless measurement report, the 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 because the time of T2 arranges the random case that the short Interference Detection that causes arrives, avoid optimizing continually the frequency configuration, influence carrying out of Femto base station regular traffic; If said process is carried out in circulation, then can be after this frequency Interference Detection finish, the report cycle that recovers the wireless measurement report is Interval A, reduces the signaling consumption of Femto base station and UE, and the processing burden that reduces the Femto base station.
In step S202 and S204, the setting to UE reports the report cycle of wireless measurement report can realize by Femto base station sending measuring control message.
Message can be controlled to the UE in the residential quarter by sending measuring in the Femto base station, in the cycle that allows UE expect with the Femto base station, periodically reports the wireless measurement report, and comprise the measured value of required reflection channel quality in wireless measurement is reported.
The report cycle of wireless measurement report is set by the Reporting interval in the measurement control message that issues particularly.

The S301:Femto base station obtains the last T1+T2 in the time period, the report of the wireless measurement of the reception signal strength signal intensity of each adjacent residential quarter that UE reports in this residential quarter;
The S302:Femto base station is according to the report of the wireless measurement of this residential quarter that obtains among the step S301, determines that this residential quarter can be with the jamming performance value of each frequency in the frequency tabulation;
The S303:Femto base station disposes one or more frequencies that jamming performance value minimum is used in this residential quarter.

In step S302, according to the wireless measurement report of obtaining among the step S301, calculate if certain frequency in the available frequency tabulation is used in the Femto base station, when the frequency identical with this frequency used in adjacent residential quarter, under current wireless environment, the interference level value that this residential quarter is subjected to namely equals the jamming performance value of this frequency.
Alternatively, can adopt following method to determine the jamming performance value of frequency.At each frequency in the available frequency tabulation of this residential quarter, the Femto base station judge whether to exist comprise with this available frequency tabulation in the wireless measurement report of adjacent subdistrict frequency point of frequency point co-frequency, if not, then determine the least interference performance number of jamming performance value for presetting of this frequency in this available frequency tabulation; If the mean value that the adjacent residential quarter of then determining to obtain receives the reception signal strength values in the wireless measurement report that adjacent subdistrict frequency point value and each adjacent residential quarter of this frequency point co-frequency in should available frequency tabulation in the wireless measurement report of signal strength signal intensity receive signal strength signal intensity is the jamming performance value of this frequency.
Some frequencies of disturbing the performance number minimum exist a plurality of, and then picked at random is one or more.The number of choosing frequency can be the frequency number that the Femto base station need dispose.
Adopt the method for the optimization frequency configuration among the embodiment two, when the Femto base station is subjected to strong jamming at definite frequency, optimize the frequency configuration, reduce and disturb, guarantee its operate as normal.By the wireless measurement report that UE periodically reports, only needing increases respective handling in the Femto base station side, realizes that difficulty is low.
