Step 303: according to the uplink channel information, using the uplink channel information and the descending channel information it Between reciprocity determine the descending channel information of the cooperative base station；

Under TDD mode, there is reciprocity between the uplink channel information and descending channel information of cooperative base station. It can use the downlink that the reciprocity between the uplink channel information and the descending channel information determines the cooperative base station Channel information.

Specifically, the numerical value of uplink channel information may be constructed a matrix, carrying out transposition to the matrix be can be obtained by The matrix that the numerical value of descending channel information is constituted, to obtain descending channel information.

Step 304: judging whether the descending channel information is effective, obtain the first judging result；

Specifically, can judge whether the descending channel information is effective from following several respects:

Judge the parameter value in the descending channel information whether within the scope of default value；Indicate that channel increases with parameter value For benefit, when some parameter value is -300dBm, since parameter value is too small, hence it is evident that be lower than zone of reasonableness, it is possible to determine institute State descending channel information failure；When some parameter value is -10dBm, since parameter value is excessive, hence it is evident that be higher than zone of reasonableness, institute Also can be determined that the descending channel information failure.

Alternatively, whether the descending channel information is changed within a preset time for judgement；Because mobile terminal is logical During letter, the channel conditions between base station are influenced by outside environmental elements, are meeting dynamic changes, so downlink is believed Road information also can dynamic change.If within a certain period of time, base station is believed to the down channel of the down channel of terminal transmission data Breath never changes, then can be determined that the descending channel information failure.

Alternatively, judging whether the descending channel information can be interpreted.If the descending channel information received, wherein Numerical value occur messy code or it is all 0 situations such as, the descending channel information will be unable to interpreted.At this point, also can be determined that The descending channel information failure.

Step 305: when first judging result, which is, is, determining that the cooperative base station is in normal working condition；

Step 306: when first judging result is no, determining that the cell of the cooperative base station covering is small to fail Area.

In the present embodiment, after determining that cooperative base station is TDD mode, by obtaining the upper of the cooperative base station Row channel information can determine the descending channel information of the cooperative base station according to uplink channel information, then judge the association Whether the descending channel information for making base station is effective, so that it is determined that whether the cell of cooperative base station covering is failure cells, The accurate detection to failure cells may be implemented.

Fig. 6 is the flow chart of the detection method embodiment 4 of the failure cells of the application.As shown in fig. 6, this method can wrap It includes:

Step 401: the base station in coordinated multipoint transmission mode determines that the duplex mode of the cooperative base station is that frequency division is double Work；

Step 402: obtaining the downlink letter of the cooperative base station of all user terminal feedbacks in the coverage area of cooperative cluster Road information；The cooperative cluster be use coordinated multipoint transmission mode provided for the same area terminal service base station set, institute It states cooperative cluster and includes at least the base station in coordinated multipoint transmission mode and the cooperative base station；

Because under mode of frequency division duplexing no longer there is reciprocity between the uplink channel information and descending channel information of base station Property, therefore directly using reciprocity according to uplink channel information, thus it is speculated that descending channel information is inaccurate.It directly acquires described The descending channel information of cooperative base station is more accurately.

When again due to the descending channel information failure of the cooperative base station of user terminal feedback, can not have no Doubt determination be caused by the cooperative base station breaks down or caused by user terminal breaks down.Therefore, this implementation In example, acquisition be the cooperative base station of all user terminals feedback in the coverage area of cooperative cluster descending channel information.

Step 403: judging whether the descending channel information of the cooperative base station of all user terminal feedbacks is effective, obtains First judging result；

Specifically, can judge whether the descending channel information is effective from following several respects:

Judge whether the descending channel information for receiving user terminal feedback within a preset time；In general, it uses Family terminal can periodically feed back the descending channel information between the cooperative base station.Other base stations in cooperative cluster can be with Receive the descending channel information.If several periods are all not received by the descending channel information, so that it may determine it is described under The failure of row channel information.

It can also judge the parameter value in the descending channel information whether within the scope of default value；It is indicated with parameter value For channel gain, when some parameter value is -400dBm, since parameter value is too small, hence it is evident that be lower than zone of reasonableness, it is possible to Determine the descending channel information failure；When some parameter value is -10dBm, since parameter value is excessive, hence it is evident that be higher than reasonable model It encloses, so also can be determined that the descending channel information failure.

Or, it can be determined that whether the descending channel information is changed within a preset time；Because of mobile terminal In communication process, the channel conditions between base station are influenced by outside environmental elements, are meeting dynamic changes, or less Row channel information also can dynamic change.If within a certain period of time, base station is believed to the downlink of the down channel of terminal transmission data Road information never changes, then can be determined that the descending channel information failure.

Or, it can be determined that whether the descending channel information can be interpreted.If the descending channel information received, Numerical value therein occur messy code or it is all 0 situations such as, the descending channel information will be unable to interpreted.At this point, can also be with Determine the descending channel information failure.

Step 404: when first judging result, which is, is, determining that the cooperative base station is in normal working condition；

Step 405: when first judging result is no, determining that the cell of the cooperative base station covering is small to fail Area.

In the present embodiment, after determining that cooperative base station is mode of frequency division duplexing, by the coverage area for obtaining cooperative cluster The descending channel information of the cooperative base station of interior all user terminal feedbacks, then judge the cooperation base of all user feedbacks Whether the descending channel information stood is effective, so that it is determined that whether the cell of cooperative base station covering is failure cells, it can also be with Realize the accurate detection to failure cells.

Fig. 7 is the flow chart of the detection method embodiment 5 of the failure cells of the application.As shown in fig. 7, this method can wrap It includes:

Step 501: the base station in coordinated multipoint transmission mode determines that the duplex mode of the cooperative base station is that the time-division is double Work；

Step 502: obtaining the uplink channel information that the cooperative base station is sent；The uplink channel information is the cooperation Base station uses the uplink channel information of the user terminal of coordinated multipoint transmission mode service；

Step 503: according to the uplink channel information, using the uplink channel information and the descending channel information it Between reciprocity determine the descending channel information of the cooperative base station；

Under mode of frequency division duplexing, if the down channel letter of the cooperative base station of user terminal feedback can not be got Breath can also then speculate the descending channel information of the cooperative base station using reciprocity by force.Certainly, this is to sacrifice detection side The accuracy of method is cost.

Specifically, the numerical value of uplink channel information may be constructed a matrix, carrying out transposition to the matrix be can be obtained by The matrix that the numerical value of descending channel information is constituted, to obtain descending channel information.

Step 504: judging whether the descending channel information is effective, obtain the first judging result；

Specifically, can judge whether the descending channel information is effective from following several respects:

Judge the parameter value in the descending channel information whether within the scope of default value；Indicate that channel increases with parameter value For benefit, when some parameter value is -500dBm, since parameter value is too small, hence it is evident that be lower than zone of reasonableness, it is possible to determine institute State descending channel information failure；When some parameter value is -10dBm, since parameter value is excessive, hence it is evident that be higher than zone of reasonableness, institute Also can be determined that the descending channel information failure.

Alternatively, whether the descending channel information is changed within a preset time for judgement；Because mobile terminal is logical During letter, the channel conditions between base station are influenced by outside environmental elements, are meeting dynamic changes, so downlink is believed Road information also can dynamic change.If within a certain period of time, base station is believed to the down channel of the down channel of terminal transmission data Breath never changes, then can be determined that the descending channel information failure.

Alternatively, judging whether the descending channel information can be interpreted.If the descending channel information received, wherein Numerical value occur messy code or it is all 0 situations such as, the descending channel information will be unable to interpreted.At this point, also can be determined that The descending channel information failure.

Step 505: when first judging result, which is, is, determining that the cooperative base station is in normal working condition；

Step 506: when first judging result is no, determining that the cell of the cooperative base station covering is small to fail Area.

In the present embodiment, after determining that cooperative base station is mode of frequency division duplexing, by obtaining the upper of the cooperative base station Row channel information；According to the uplink channel information, using between the uplink channel information and the descending channel information Reciprocity determines the descending channel information of the cooperative base station；Judge whether the descending channel information of the cooperative base station has again Effect can not obtain described in user feedback so that it is determined that whether the cell of cooperative base station covering is failure cells When the descending channel information of cooperative base station, the detection to failure cells is realized.

It should be noted that determining the cooperative base station covering in method in any one embodiment of the application Cell be failure cells after, the failure cells can also be compensated.In practical applications, it can be directly used One base station compensates the failure cells, can also notify other cooperative base stations jointly to the failure by first base station Cell compensates.

When directlying adopt first base station and being compensated to the failure cells, it can increase described in coordinated multipoint transmission The transmission power of the base station of mode, to carry out failure compensation to the failure cells；

And/or increase the height of the antenna of the base station in coordinated multipoint transmission mode, so as to small to the failure Area carries out failure compensation；

And/or reduce the angle of declination of the antenna of the base station in coordinated multipoint transmission mode, so as to the failure Cell carries out failure compensation.Wherein, angle of the angle of declination between the antenna and vertical plane.

When notifying other cooperative base stations to compensate jointly to the failure cells by first base station, it can determine and institute State the failure compensation cooperative base station that cooperative base station carries out coordinated multipoint transmission；The failure compensation cooperative base station can be used for pair The cooperative base station carries out the base station of failure compensation using coordinated multipoint transmission technology；

The failure compensation cooperative base station is notified to carry out failure compensation to the failure cells.

Usually, the base station of the adjacent area of the failure cells can be used as failure compensation cooperative base station.

Since the covering performance for edge customer can be improved using coordinated multipoint transmission technology, so being assisted using multiple spot Make transmission technology and carry out failure compensation, the effect of failure compensation can also be improved.

It should also be noted that, when carrying out failure compensation to the failure cells using coordinated multipoint transmission technology, also It can be selected according to the Reference Signal Received Power (Reference Signal Receiving Power, RSRP) of user terminal Select multi-user's multiple-input and multiple-output (MU-MIMO) mode or the single user multiple-input and multiple-output in coordinated multipoint transmission technology (SU-MIMO) mode is that the user terminal carries out failure compensation.Specifically, the reference signal of available user terminal receives Power；

Judge whether the Reference Signal Received Power is greater than preset threshold, obtains the second judging result；

When second judging result, which is, is, use the MU-MIMO mode in multicast communication technology whole for the user End carries out failure compensation；

When second judging result is no, use the SU-MIMO mode in multicast communication technology whole for the user End carries out failure compensation.

This is because the higher user terminal of RSRP can share a running time-frequency resource with other users terminal, therefore can Failure compensation is carried out for the user terminal in a manner of MU-MIMO to use；And the lower user terminal of RSRP is received due to itself The signal arrived is just weaker, so the speech quality in order to guarantee the lower user terminal of RSRP, can use SU-MIMO for institute It states user terminal and carries out failure compensation, so that the user terminal no longer shares running time-frequency resource with other users terminal.
