Embodiment
Lift specific embodiment below, the present invention is further detailed explanation.
Embodiment one
Present cellular system major part all adopts the dipole polarization antenna, such antenna in the gain of main lobe direction much larger than other directions.If should be from the signal of A antenna emission, actual in the emission of B antenna, two different situations in antenna horizontal direction angle, the signal strength signal intensity that the signal of A antenna main lobe direction emission will emit much larger than the B antenna.With the A position among Fig. 1 is example, if this signal sends from A antenna 1, then signal strength signal intensity may be-30dBm, because it is positioned at the main lobe direction of A antenna, if this signal sends from B antenna 2, then may be-50dBm, because be the signal of coming from the secondary lobe of B antenna in the signal strength signal intensity that receives at A place.As shown in Figure 2, as an embodiment, this method specifically comprises:
The measurement report that reports of receiving mobile at first;
In general, when travelling carriage takies TCH channel (Traffic Channel, Traffic Channel) per 104 multi-frames can report the one-shot measurement report time, the main BCCH level intensity of the descending level of current carrier frequency and current area can be carried in the measurement report, therefore by reading descending level and the main BCCH level that measurement report can obtain current carrier frequency; Here distinguish for current carrier frequency and main BCCH carrier frequency, in the GSM cellular system, all can there be a main BCCH carrier frequency in each sub-district usually, and the current carrier frequency here specifically then is meant the shared carrier frequency of setting up by travelling carriage of current talking.
Next the descending level of current carrier frequency and the main BCCH level intensity of sub-district are compared;
Need to prove, because main B carrier frequency all is the full power emission at each time slot, do not take the power control measure, therefore do not need generally speaking different main B carrier frequency is compared, only relatively the descending level of current carrier frequency and the level of main B carrier frequency get final product.
Whether the absolute value of the descending level by relatively judging described current carrier frequency and the difference of main Broadcast Control Channel carrier frequency level more than or equal to default level differences thresholding, is connected with the antenna feeder of main Broadcast Control Channel carrier frequency and makes mistakes if be greater than or equal to default thresholding then feed back current carrier frequency.
Embodiment two
As shown in Figure 2, the technical scheme of present embodiment comprises following steps:
The measurement report that step 201, receiving mobile report;
In general, main B carrier frequency is in the full power emission always, so that the sub-district residing network of mobile station in selecting the best; And the channel on other carrier frequency only can full power be launched when just activating, may power be lowered because having taked downlink power control afterwards, but no matter whether open descending power control, can reflect the level of current carrier frequency maximum downstream level and main BCCH at the several measurement reports that report at the beginning.Therefore, in the present embodiment,, can choose travelling carriage and rigidly connect preceding 2 measurement reports into channel in order further to improve the precision that detects.Simultaneously, because travelling carriage is crossed near apart from the base station or crossed far whether wrong all may cause than mistake for measuring antenna feeder, in order further to reduce error, we also can the measurement report of lead TA value access time between 1 to 5.It is pointed out that these the two kinds purposes of choosing mode all are to reduce error in order to improve precision, two conditions both can adopt separately also and can adopt simultaneously.
(Discontinuous Transmission DTX), under the DTX pattern, has only 12 frame data effectively inevitable usually, and other do not have transmitting power constantly probably because the downlink discontinuous emission may have been opened in the sub-district; And under non-DTX pattern, at least 100 frames all must transmit in common 104 frames, so precision and reliability in order to improve detection, we can distinguish this two kinds of different emission modes, if descending DTX has been enabled in the sub-district, then the SUB value in the measurement report is sampled,, then the FULL value in the measurement report is sampled if descending DTX is not enabled in the sub-district.
In addition, because wireless signal exists Rayleigh decay and multipath effect when propagating, therefore in order further to improve the sum of errors accuracy that detects, in the process of the level that obtains descending level and main B according to measurement report, can carry out rational filtering to measurement report data.When carrying out filtering, can consider to use various known filtering methods, such as time filtering method, promptly set a rational sampling period, as an embodiment, the sampling period of acquiescence can be made as 8 minutes, and the maximum sampling period can be made as 64 minutes, the filtering step-length can be made as 2 minutes, triggered described judgement when the sampling time reaches described sampling period; Adopt the quantity filter method for another example, promptly set a minimum number of samples thresholding, as an embodiment, the number of samples thresholding can be made as 128 times, the judgement of triggering following when number of samples reaches more than 128 times; Need to prove, comprise that the various known filtering method of these two kinds of filtering methods both can use separately, also can be used as the constraints combination and use.
In addition, after the connection of judgement antenna feeder makes mistakes, can also further trigger and report to the police:
Enter step 205: when the alarm ratio surpasses the preset alarm thresholding, trigger alarm;
Specifically, can introduce the notion of an alarm ratio, the alarm ratio is set to surpass the sampling number of level differences thresholding and the ratio of sampling total degree, by court verdict is repeatedly added up,
As an embodiment, alarm ratio thresholding can be set to 80%, promptly triggers carrier alarm when the sampling number that surpasses the level differences thresholding reaches sampling total degree 80%.By alarm is set, can be easy to the authenticity of the problem of determining and the relation of line wrong, in practical operation, for the service engineer, only need website to check that directly the alarm carrier frequency gets final product, and can improve the efficient of maintenance greatly.
Embodiment three
As shown in Figure 3, the checkout gear that present embodiment provides a kind of carrier frequency to be connected with antenna feeder, this device specifically comprises:
Receiver module is used for the measurement report that receiving mobile reports;
Processing module, be used for obtaining the level of the main BCCH channel of broadcast control carrier frequency of the descending level of current carrier frequency and current area according to described measurement report, wherein, as an embodiment, processing module can also comprise sampling module, enabled downlink discontinuous emission DTX when finding the sub-district, SUB value in the described measurement report is sampled, if the downlink discontinuous emission is not enabled in the sub-district, then the FULL value in the described measurement report is sampled, sampling module be can certainly omit,, the main B level that carries in the measurement report and the descending level of current carrier frequency directly read without sampling.In addition, in order further to improve accuracy of detection, processing module can also comprise a filtration module, by filtration module the back data of sampling is carried out further filtering.
Whether judging module, the absolute value of difference that is used to adjudicate the descending level of described current carrier frequency and main BCCH carrier frequency level more than or equal to default level differences thresholding, if then feed back current carrier frequency and be connected with the antenna feeder of main BCCH carrier frequency and make mistakes.In addition, in order further to improve the efficient of safeguarding,, in carrier frequency and checkout gear that antenna feeder is connected, can also comprise an alarm module, report and alarm when finding that antenna feeder connects the ratio of makeing mistakes above the preset alarm thresholding as an embodiment.
