Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The inventive method embodiment 1
Present embodiment provides a kind of fault detection method of base station system, as shown in Figure 2, comprising:
Wherein, RSSI information is carried out timing detection by TRX to main collection reverse signal and diversity reverse signal and is obtained, and reports base band processing device by TRX.RSSI information be used to indicate receiving belt in wide useful signal and the power summation of other noise signals, with the end of weighing the residing wireless environment of the base station system situation of making an uproar.
By the lot of data statistical results show, when RSSI information is lower than a certain lower threshold, then represent the receiving unit device failure on the TRX veneer, device fault has taken place.
By the described method of present embodiment, thereby by reverse signal intensity indicated in the RSSI information being detected the device fault that can in time detect TRX, so that can in time repair, avoid further influence to systematic function, improved user's satisfaction and service quality.
The inventive method embodiment 2
In base station system, except the easy generating device fault of TRX, main line concentration cable in the reverse signal transmission channel or diversity cable also are the main sources that fault takes place, in order to realize cable is connected the detection of fault, present embodiment provides the fault detection method of another kind of base station system, as shown in Figure 3, comprising:
Wherein, the process chip of existing base band processing device can periodically report one time branch information usually at set intervals, is used to notify the reverse signal of this institute of branch demodulation to comprise which main collection reverse signal or diversity reverse signal.Branch reports the number of times information table to understand that base band processing device carries out times of reporting to the branch information of every kind of reverse signal, promptly shown the number of times of main collection reverse signal, and the diversity reverse signal inserts the number of times of base band processing device by the diversity backward channel by main collection backward channel access base band processing device.
Wherein, to report the reverse signal of number of times be main collection reverse signal if having low branch, the cable that cable connects fault then may take place comprise: connect the first main line concentration cable of antenna feeder device and duplexer and be connected duplexer and the second main line concentration cable of TRX; Correspondingly, to report the reverse signal of number of times be the diversity reverse signal if having low branch, the cable that cable connects fault then may take place comprise: connect the first diversity cable of antenna feeder device and duplexer and be connected duplexer and the second diversity cable of TRX.Need to prove herein, because the 3rd cable between TRX and the base band processing device is generally optical cable rather than radio frequency cable, and this section optical cable is not distinguished main collection signal and diversity signal, so its fault can detect by other method of the prior art, repeats no more herein.
Under normal conditions, stochastic behaviour is all satisfied in the distribution of portable terminal.Therefore, from the statistics of long period, reverse signal enters number of times that branch's receiver handles and enters the number of times that branch's receiver handles from the diversity backward channel from the backward channel of main collection should be suitable on the order of magnitude.That is to say, if reporting, the branch of main collection reverse signal and diversity reverse signal differs unusual between the number of times, when reporting the ratio of number of times to reach prearranged multiple as both branch, then branch report the few reverse signal of number of times the reverse path of process probably break down.
By the described method of present embodiment, realized cable is connected the detection of fault by the detection that reports number of times to reverse signal, the cable that makes the system manager can find in time that base station system occurs connects fault, so that can in time repair, avoided further influence, improved user's satisfaction and service quality systematic function.
The inventive method embodiment 3
Present embodiment is further improved on the basis of method embodiment 2, as shown in Figure 4, comprising:
Step 301～304 are similar with method embodiment 2 described step 201～204, repeat no more herein.
Step 305 when step 304 is finished after branch to main collection reverse signal and diversity reverse signal reports the comparison of number of times, reports the ratio of number of times to reach prearranged multiple as both branch, then further reverse signal intensity and default upper limit threshold is compared.When reverse signal intensity is higher than upper limit threshold, execution in step 310; When reverse signal intensity is higher than lower threshold and is lower than upper limit threshold, execution in step 320.Wherein, reverse signal intensity comprises main collection reverse signal intensity and diversity reverse signal intensity.
Step 310 is sent cable and is connected the fault cue.
Step 320 is sent cable and is connected fault cue and device fault cue.
Wherein, according to existing statistics, when reverse signal intensity was higher than default lower threshold and is lower than upper limit threshold, cable connected fault and device fault all might take place.This is because when whole backward channel mainly is made of analogue device, when accurately detecting, still can there be a fuzzy area, promptly when reverse signal intensity is higher than lower threshold XdBm and is lower than upper limit threshold YdBm, wherein X is less than Y, if the ratio that reports number of times of main collection reverse signal and diversity reverse signal is during greater than N times, both may exist cable to connect fault, also may have the device fault of TRX, therefore can send two kinds of fault cues.
In addition, because cable connects fault mainly is that the possibility that breaks down is bigger owing to improper the causing of connection that is caused by manual operation in the installation process; And TRX carried out strict test when dispatching from the factory, and than the fault that manual operation causes, the probability that TRX breaks down is less.Therefore, all right execution in step 321 is sent cable and is connected the preferential cue of fault, get rid of cable with the prompting user priority and connect fault, still there is fault if cable connects after fault is excluded, then considers again to get rid of device fault, can improve the efficient that fault is got rid of so as far as possible.
By the described method of present embodiment, when testing result is in fuzzy area, sent two kinds of fault cues to the system maintenance personnel, avoided delay owing to the inaccurate breakdown maintenance that causes of testing result, thereby further guaranteed the normal operation of system, improved service quality.
