In addition, before execution in step 401, the network maintenance staff also can judge whether the base station needs to eliminate up external disturbance according to the practical operation situation of base station, if need, then execution in step 401;
Here,: the carrier frequency uplink receiving performance number of the base station that provides according to the detection of OMC control software or professional value of making an uproar of the up end of carrier frequency when idle can be provided in described judgement, when carrier frequency uplink receiving performance number or when professional idle the value of making an uproar is not in normal range (NR) at the carrier frequency up end time, being judged to be needs the up external disturbance of elimination; Wherein, described normal range (NR) is interior for to judge according to actual conditions, such as, the normal range (NR) of the value of making an uproar of the up end of carrier frequency during the professional free time can be for being lower than-174dB;
Also can for: according to prior art, judge that the base station need to eliminate up external disturbance.
Further, different according to the Rule of judgment of determining execution in step 401, after step 402 is finished, can carry out different subsequent treatment, concrete:
When according to carrier frequency uplink receiving performance number or the value of making an uproar of the up end of carrier frequency not in normal range (NR), being judged to be needs to eliminate up external disturbance, during execution in step 401, after step 402 is finished, the carrier frequency uplink receiving performance number of network maintenance staff's base stations detected or the value of making an uproar of the up end of carrier frequency, judge whether its carrier frequency uplink receiving performance number or the value of making an uproar of the up end of carrier frequency return in the normal range (NR), if normal, whether the speed of then checking the upstream data service of base station is in normal range (NR), if normal, determine that then this base station is subject to up external disturbance, and up external disturbance is eliminated, if undesired, then determine the not former main equipment internal fault because of the base station in normal range (NR) of the carrier frequency uplink receiving performance number of this base station or the value of making an uproar of the up end of carrier frequency, then do the detection of the main equipment internal fault of further base station according to prior art, do not do here and give unnecessary details; Wherein, described upstream data service speed is in the normal range (NR) for deciding according to the situation of base station, actual place, such as, enhanced data rates for gsm evolution technology (EDGE, Enhanced Data Rate for GSM Evolution), EVDO, HSUPA, Long Term Evolution (LTE, Long Term Evolution) the base station in the communication system such as, the normal range (NR) of determining upstream data service speed for reference according to normality condition and the standard index of this place, base station system is not respectively done here and is given unnecessary details;
When according to prior art, judge that the base station need to eliminate up external disturbance, when determining execution in step 401, after step 402 is finished, can carry out subsequent treatment according to prior art, do not do here and give unnecessary details.
Below be the theory derivation to the result of use of scheme provided by the invention: the gross power in the signal bandwidth that the antenna opening of the antenna-feedback system of the RTWP value representation base station that the base station reports detects, comprising following four class interference powers: makes an uproar in the end of base station digital intermediate frequency device analog to digital converter (ADC); Antenna opening thermal noise after the amplification that base station digital intermediate frequency device ADC receives; The mobile phone upward signal of the antenna opening after the amplification that base station digital intermediate frequency device ADC receives; The external interference signals of the antenna opening after the amplification that base station digital intermediate frequency device ADC receives.The base station is calculated the RTWP value and is equaled ADC detection gross power divided by the radio-frequency channel gain of base station.
When the base station reports RTWP=-93dBm, judge that this RTWP value is as unusual, after then device provided by the invention being adopted in this base station, can occur following two kinds may: one, suppose the RTWP value be elevated to-93dBm causes by the mobile phone signal (typical scene) of making an uproar at the bottom of external disturbance, the base station and be lower than 50% load, the device that the application of the invention provides is to base station upward signal decay 10dB, behind RTWP value reduction 7-10dB; The RTWP value that the base station reports returns in the normal range (NR) (namely-103dBm between-the 106dBm), upstream data service recovery normal consistency (returning to normal speed greater than 1MBit from 50-200Kb such as, speed);
Two, suppose that it is owing to the inside of base station reason causes that the RTWP value raises, after then using device provided by the invention to the decay of base station upward signal, the inside total noise power that ADC detects can not change, but that system can strengthen the transmitting power of mobile phone is constant with the signal to noise ratio (S/N) of guaranteeing the ADC receiver stage; As seen, use device provided by the invention to after the base station upward signal decay, the RTWP value that the base station reports is constant.So the present invention disturbs inside of base station can not play the effect that improves and eliminate.Above theory can prove, the too high reason of RTWP value of using the present invention can distinguish rapidly the base station is that external disturbance causes or inside of base station disturbs and causes, and the interference that upstream data service is caused of energy quick solution external disturbance.Above theoretical derivation result and outfield experiments the result fit like a glove.
As seen, scheme that the application of the invention provides, up/down row signal to the base station carries out separating treatment, do not affect the downstream signal that will send from the antenna-feedback system of the main equipment method phase base station of base station, the signal that the antenna-feedback system of base station can be received is simultaneously decayed, after finishing by decay, disturb and whether be excluded to judge internal system unusually or external disturbance, thereby avoid the investigation process to the external interference source of upward signal, improve the treatment effeciency of external disturbance, and then guarantee the upstream data service performance of base station and user's experience;
Further, decay by signal that the base station is received, can produce decay to up external disturbance, thereby make the base station more easily extract upward signal, in addition, the base station is to the measurement through the upward signal of overdamping, and the terminal of sending upward signal corresponding according to prior art control promotes transmitted power, and then can easier upward signal and the external disturbance that the base station is received distinguish.
The above is preferred embodiment of the present invention only, is not for limiting protection scope of the present invention.
