Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme of the embodiment of the invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the described embodiment among the present invention, the every other embodiment that those skilled in the art are obtained under the prerequisite of not making creative work should belong to the scope of protection of the invention.
At first in conjunction with the method 100 of Fig. 1 description according to the detection reverse fault of the embodiment of the invention.Method 100 is carried out by network equipment.Network equipment can be base station, IAD etc.
As shown in Figure 1, at the S120 of method 100, generate the test signal that is used to detect reverse fault; Then, test signal is carried out demodulation process, obtain processing signals at S140; At S160, obtain the correct result of test signal correspondence then; At S180, processing signals is compared with correct result again,, then determine to exist reverse fault if processing signals is different with correct result.
Network equipment generates test signal in inside, with test signal as the input signal that is used to detect reverse fault.Then according to network equipment to Base-Band Processing operation from the signal of user terminal, the test signal that is generated is carried out a series of signal processing, the processing signals after obtaining handling.The corresponding correct result of the test signal of obtaining then and being generated is used for comparing with the processing signals that obtains.After relatively, if both differences then can be determined to have reverse fault in network equipment inside.
The method of the detection reverse fault that provides according to the embodiment of the invention, by producing test signal in network equipment inside, and in a series of processing of network equipment internal operation, can finish the detection of reverse fault and need not to rely on extraneous test condition by network equipment self, improved detection efficiency, and can realize detection accurately and rapidly reverse fault.
Particularly, in S120, generate the test signal that is used to detect reverse fault.
The method 200 of generation test signal that according to one embodiment of present invention, can be by as shown in Figure 2 obtains test signal.
In S220, obtain predefined result.
Predefined result can be the result that the expectation supposed in advance obtains, for example bit stream, array or the character string etc. that obtain of expectation.
In S240, generate the input signal corresponding with predefined result, with input signal as test signal.
According to the predetermined communication standard such as CDMA2000, WCDMA, TD-SCDMA, LTE (Long Term Evolution), can be according to the counter input signal of releasing correspondence of predefined result.That is to say,, need what kind of signal of input so according to the processing specification in the scheduled communication standard if obtain such result.For example,, then can derive the bit stream of needs input, be assumed to be " 001000110101 " according to communication standard if the result that expectation obtains is " ABC ".This bit stream is an input signal so, with it as the test signal that is used to detect reverse fault.
After having generated test signal according to method 200, the correct result among the S160 is exactly this predefined result.At this moment, the correct result who obtains the test signal correspondence obtains predefined result exactly as correct result.
The method 300 of generation test signal that according to another embodiment of the present invention, can also be by as shown in Figure 3 obtains test signal.
With reference to figure 3, in S320, call backward channel, backward channel comprises the required parameter information of generation test signal.
Backward channel is the shared channel of signal that is sent to network equipment by user terminal.Network equipment can be that user terminal distributes backward channel according to the request of user terminal, and distributing the process of backward channel is to call the process of backward channel, also can be interpreted as visually and open backward channel.Network equipment also can call some backward channels (for example Common Control Channel etc.) all the time and use for user terminal, and these backward channels are in open mode all the time.After after backward channel is opened, just calling, need generate the signal that in backward channel, transmits according to the relevant parameter information of backward channel.
The backward channel that network equipment calls (opening) has comprised and has been used to generate test signal parameters needed information.Parameter information can be to generate the signal parameters needed information that network equipment can be discerned and handle according to communications standard-specific.For example, CDMA2000, WCDMA, TD-SCDMA, etc. in the communication standard, parameter information can comprise short code, long code, data packet length, code check, modulation system etc.Need generate the signal that network equipment can be discerned and handle according to the parameter information that backward channel provides.The parameter information of backward channel provides the channel information part for the generation of test signal.
Network equipment can periodically call backward channel, periodically to start the detection to reverse fault.In addition, can also when satisfying predetermined condition, call backward channel.For example, when network equipment finds not have within the predetermined time user terminal to insert, start timer, if timer expiration does not still have user terminal to insert, then call backward channel, to start detection to reverse fault.Perhaps when network equipment finds that the user terminal quantity that inserts is lower than predetermined threshold, call backward channel.No matter be periodically to call backward channel or condition to trigger to the calling of backward channel, can both be in time and find the existence of reverse fault on one's own initiative.
In S340, generate the information source data that comprise binary bit stream.
The information source data can be the determined data messages that should import of result of the network equipment that obtains according to expectation, also can be the data messages that generates arbitrarily.The information source data can comprise the binary bit stream of random length, for the generation of test signal provides effective data division.
In S360, generate test signal according to parameter information and information source data.
Can be according to the regulation in the scheduled communication standard, the information source data that generate among parameter information that comprises by the backward channel that calls among the S320 and the S340 produce test signal.The scheduled communication standard can be communication standards such as CDMA2000, WCDMA, TD-SCDMA, LTE, stipulated how to generate the signal that network equipment can be discerned and handle, for example how to encode therein, how spread spectrum, how to modulate, how the composition data bag, what sequential to require output etc. with.Network equipment is followed predetermined communication standard, according to parameter information and information source data, can obtain being used to detect the test signal of reverse fault.This test signal can be equivalent to the digital baseband signal that the expectation that is generated by user terminal sends to network equipment.
Above the order of the each several part of the method 300 of Miao Shuing is not construed as limiting scope of the present invention.For example, though above the mode of carrying out S340 again with first execution S320 has been described method 300, but method 300 also can be carried out S340 earlier and carry out S320 again, perhaps carries out S320 and S340 side by side, as long as had parameter information and information source data before carrying out S360.
Generating under the situation of test signal by method 300, the correct result who is obtained among the S160 can be the result of calculating according to the scheduled communication standard meter corresponding with test signal, also can be the check results that calculates according to test signal, can also be parameter relevant with the length of test signal etc.
According to the method 300 that generates test signal, owing to can call different backward channels flexibly, and can generate the information source data arbitrarily, therefore, can produce test signal neatly.Certainly, it may occur to persons skilled in the art that, except in the process that detects reverse fault, dynamically generating the test signal, can also be in advance one or more test signals that are used for detecting reverse fault be stored in network equipment, when needs detect reverse fault, from the test signal of being stored, select one as detecting required input signal.
Return Fig. 1, in S140, test signal is carried out demodulation process, obtain processing signals.
The demodulation process of network equipment can be equivalent to network equipment and receive from the signal of user terminal and be converted into performed signal processing after the baseband digital signal.In demodulation process, can comprise demodulation to baseband signal, can also comprise signal processing such as despreading to baseband signal, decoding.According to embodiments of the invention, network equipment can be with the test signal that generates as the baseband digital signal from user terminal, it is carried out a series of operations that meet the scheduled communication standard such as despreading, demodulation, decoding, obtain the processing signals after the demodulation process.
In S160, obtain the correct result of test signal correspondence.
Generating based on predefined result under the situation of test signal, this predefined result is exactly the correct result of test signal correspondence.The process of obtaining correct result is exactly to obtain the process of predefined result.For example, expecting to obtain " ABC " result as mentioned above and generating under the situation of specific bit stream that " ABC " is exactly the corresponding correct result of test signal (specific bit stream).
Can also be according to the result of scheduled communication criterion calculation test signal correspondence, with the result calculated as described correct result.Owing to how in predetermined communication standard (as CDMA2000, WCDMA, TD-SCDMA, WiMAX, LTE etc.), to have defined the standard of processing signals, therefore can calculate the result that should obtain after the correct processing test signal according to the correct flow process in the communication standard, with the result that calculates as correct result.
In addition, can also obtain the correct check results of test signal correspondence as correct result.For example, can directly calculate test signal corresponding check result based on the check information in the test signal, with the check results calculated as correct result.In addition, correct check results of being obtained or correct result also can be the particular values that shows that verification is correct.For example, represent in " 0 " that verification is correct, " 1 " is represented under the situation of check errors, the correct result who is obtained is " 0 ".
Certainly, those skilled in the art can also be provided with that other are used to detect test signal with the corresponding result of test signal.For example, can be the useful data part of carrying in the test signal or test signal itself etc.The correct result of test signal correspondence can be stored in advance in the network equipment, also can or calculate correct result etc. when generating test signal afterwards.
In S180, processing signals is compared with correct result, if processing signals is different with correct result, then determine to exist reverse fault.
The correct result that processing signals that S 140 is obtained and S160 obtain compares, and judges whether both there are differences.If by finding that relatively processing signals is different with correct result, then can determine to exist reverse fault in network equipment.Reverse fault causes the demodulation process operation exception, has influenced the correct processing to test signal.Can determine thus, if what enter network equipment is reverse signal from user terminal, then because network equipment signal processing existing problems can't correctly be handled reverse signal.
Otherwise, if processing signals with correctly come to the same thing, illustrate that then the demodulation process operation of network equipment is normal, do not have reverse fault to exist.
The content of processing signals and correct result's content can be compared, when both contents not simultaneously, have reverse fault.Certainly, it may occur to persons skilled in the art that except comparison process signal and correct result's content, can also compare other information.For example, whether length that can the comparison process signal is identical with correct result's length, if then there is reverse fault in both length differences.The check results of processing signals can also be compared with the correct result as correct check results who is obtained, if difference then have reverse fault.This correct check results can be the fixed value of being scheduled to (representing the verification correct as " 0 "), also can be the check results that should obtain that calculates according to test signal, can also be the one or more possible correct result who obtains according to the check information in the processing signals.For instance, whether detect processing signals by the check information in the processing signals correct, if it is incorrect then have reverse fault, can be the equal of to have obtained one or more possible correct results by check information this moment, with processing signals and the possible conclusion that correct comparison as a result drew, perhaps can be equivalent to the conclusion that the check results that will calculate based on the check information in the test signal and specific correct check results comparison are drawn.Above-mentioned manner of comparison can individualism, also can and deposit.For example, when and when depositing, can wait according to computation complexity, resource limit and select suitable manner of comparison.
Though described method 100 with the order of carrying out earlier S120 and S140, carrying out S160 again, but S160 can be positioned at before the S120, also can be positioned at after the S120, before the S140,, obtain processing signals and correct result gets final product as long as before S180 comparison process signal and correct result.
The method of the detection reverse fault that provides according to the embodiment of the invention, by producing test signal in network equipment inside, and in a series of processing of network equipment internal operation, can finish the detection of reverse fault and need not to rely on extraneous test condition by network equipment self, improved detection efficiency, and can realize reverse fault is detected more accurately and rapidly.
According to an embodiment more of the present invention, after S180, can also recover automatically reverse fault.For example, when determining to have reverse fault, can start the backup flow process of demodulation process operation, also can upgrade existing procedure with the original flow process of demodulation process that is stored in the network equipment, the demodulation process to reverse signal is carried out in other network equipments helps that can also accuse.Certainly, those skilled in the art it will also be appreciated that other recover the mode of reverse fault automatically.By automatic recovery to reverse fault, can overcome and need improve the efficient that solves reverse fault by manpower to the shortcoming that the reverse fault of network equipment carries out manual reversion, provide cost savings.
