Specific embodiment

Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that in the case where not conflicting, The feature in embodiment and embodiment in the application can be mutually combined.

It should be noted that term " first ", " second " in description and claims of this specification and above-mentioned accompanying drawing etc. is to use In the similar object of difference, without for describing specific order or precedence.

A kind of compensation method of cell self-healing is provided in the present embodiment, and Fig. 1 is cell self-healing according to embodiments of the present invention The flow chart one of compensation method, as shown in figure 1, the flow comprises the following steps：

Step S102, determines the compensation cell of fault cells, wherein it is determined that compensation cell quantity can be one, may be used also Think multiple.

Step S104, sends a message to base station where compensation cell, wherein, message is used to indicate to use compensation cell small to failure Area compensates.

By above-mentioned steps, base station where fault cells sends to one or more base stations where compensation cell for getting disappear respectively Breath, to indicate compensation cell to compensate fault cells, compensates as a result of compensation cell to the cell for breaking down, Solve in the prior art because cell breaks down or cell fault recovery unsuccessfully causes the cell coverage area asking for blind area occur Topic, the technique effect of Consumer's Experience sense is improved so as to reach.

The message sent to the base station where compensation cell can have many kinds, small in failure in an optional implementation method Before area carries out self-healing compensation, message arrangement new information can be respectively sent to one or more base stations where compensation cell selected (eNB CONFIGURATION UPDATE), the message is third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) the existing message of agreement, to eNB CONFIGURATION UPDATE messages Message body (Served Cells To Delete) increase compensation cell information (Compensation Cells Information), receive The base station of the message can be according to the Cell Global Identifier (E-UTRAN in Compensation Cells Information message Cell Global Identifier, referred to as ECGI) search corresponding compensation cell.

The method compensated to fault cells using compensation cell can have many kinds, in an optional implementation method, can To realize the compensation to fault cells by way of the coverage that cell is compensated increasing.

The fault type of cell has been likely to many kinds, in an optional embodiment, fault cells can for sleep zone or At least one in the cell of low performance.In this optional embodiment, if base station monitors cell and meets sleep zone and low During at least one in performance cell, determine that the cell is fault cells.

Determining the mode of fault cells also has many kinds, for example, in an optional embodiment, it can be determined that whether cell has The performance indications of self-healing alarm and cell whether be less than the first predetermined threshold value, then, determine cell exist self-healing alarm with And the performance indications of cell are fault cells less than cell in the case of the first predetermined threshold value, is determined.In this optional embodiment, Can be with the self-healing alarm of monitor in real time multiple cell and performance indications, in this optional embodiment, performance indications can be key Performance indicators KPI.If monitor the presence of self-healing alarm, and performance indications determine that this is small less than in the case of the first predetermined threshold value Area is fault cells, that is, determine that the cell is at least one in sleep zone and low performance cell.It should be noted that when small When area's satisfaction moves back Serving cell, it is contemplated that move back the particularity of Serving cell state behavior, the benefit that can be used in the present embodiment Compensation method is processed.

When monitoring performance index, performance indications of the adjacent cell of fault cells in preset time period, Ran Hougen can be obtained Compensation cell is determined from adjacent area according to performance indications.For example, base station where the fault cells can will obtain the neighbour to network management center Key Performance Indicator KPI of the cell in Preset Time, and compensation cell is searched from multiple adjacent cells according to KPI.Wherein, Preset Time can be chosen for three days, five days, can also be chosen for one week.Preferably, in embodiment, this can be obtained KPI of the adjacent cell of fault cells at nearly three days.

The mode of the compensation cell of fault cells is determined according to performance indications can various, in an optional embodiment, can With according to performance indications, switching times and handover success rate between statistics adjacent cell and fault cells；Wherein, switching times bag Include：The switching times of fault cells are switched to from adjacent cell, and/or, the switching times of adjacent cell are switched to from fault cells；Cut Changing power into includes：The handover success rate of fault cells is switched to from adjacent cell, and/or, switch to adjacent cell from fault cells Handover success rate, then, it is determined that switching times and handover success rate are compensation more than the adjacent cell of the second predetermined threshold value in adjacent cell Cell.

In this optional embodiment, the second predetermined threshold value can be set up, the second predetermined threshold value can include switching times thresholding (Handover Number Threshold) and handover success rate thresholding (Handover Success Threshold).For example, can be with All adjacent cells for the fault cells got in above-mentioned steps were carried out respectively to the switching times and handover success rate of nearly 3 days Initial decision.If determining adjacent cell switches to the switching times of fault cells more than switching times thresholding, and adjacent cell switching Handover success rate to fault cells is more than handover success rate thresholding, it is determined that the adjacent cell is compensation cell；If determining event again Barrier cell switches to the switching times of adjacent cell more than switching times thresholding, and fault cells switch to the handover success of adjacent cell Rate is more than handover success rate thresholding, it is determined that the adjacent cell is compensation cell.

The mode of the compensation cell of fault cells is determined according to performance indications can various, in an optional embodiment, also The switching times and handover success rate between adjacent cell and fault cells can be counted according to performance indications；Wherein, switching times Including：The switching times of fault cells are switched to from adjacent cell, and/or, the switching times of adjacent cell are switched to from fault cells； Handover success rate includes：The handover success rate of fault cells is switched to from adjacent cell, and/or, switch to adjacent cell from fault cells Handover success rate, then, switching times and handover success rate at least to adjacent cell are weighted, and obtain adjacent cell Weighted value, finally, the adjacent cell for determining weighted value maximum in adjacent cell is compensation cell.

For example, can be the weight coefficient P1 and above-mentioned reality that each adjacent cell is respectively provided with switching times thresholding in above-mentioned implementation method The weight coefficient P2 of handover success rate thresholding in mode is applied, wherein, the value of P1+P2=100%, P1 and P2 is according to network operation Data simulation draws.The switching times and adjacent cell that fault cells are switched to each adjacent cell by weight coefficient P1 and P2 switch To fault cells handover success rate weight after sue for peace, obtain the weighted value of each adjacent cell, and according to the power of each adjacent cell Weight values determine compensation cell.

It is determined that during compensation cell, candidate's compensation cell can be first selected, for example, can be according to each for calculating The weighted value of adjacent cell, tentatively selects candidate's compensation cell, wherein, the quantity of candidate's compensation cell can be one, can be with It is multiple.

Preliminary candidate's compensation cell of selecting can include following two modes：

Mode one

Weighted value result to above-mentioned each adjacent cell arranges (descending and ascending order) in order, obtains a sequencing queue.If drop Sequence sorts, then foremost (that is, weighted value is larger) is selected in sequencing queue, and can realize that X2 is connected with fault cells Adjacent cell for candidate compensate cell；Be if the candidate's compensation cell chosen is multiple, between the plurality of candidate compensation cell across The adjacent cell for standing and having X2 to be coupled.

Mode two

The weighted value of each adjacent cell need not be ranked up, the cell for meeting condition from adjacent cell selection compensates small as candidate Area, wherein, the condition be with fault cells can realize X2 be connected in the larger adjacent cell of weighted value for candidate compensates cell.If The quantity of candidate's compensation cell is multiple, then the base station belonging to the plurality of candidate's compensation cell is different base stations.

Determine to compensate the optional embodiment of cell as another kind, it is also contemplated that the load condition of adjacent cell, i.e. small to neighbour The current loads of the switching times, handover success rate and adjacent cell in area are weighted, and obtain the weighted value of adjacent cell.At this In optional embodiment, by the switching times of adjacent cell adjacent cell, handover success rate and load condition, the power of adjacent cell is obtained Weight values, can choose higher with fault cells switching relatively frequent, handover success rate by the weighted value in multiple adjacent cells, And the less cell of load is used as compensation cell.

In this optional embodiment, a load thresholding (Load Threshold) can be set up.For example, through the above way one The middle method for determining candidate's compensation cell determines that candidate compensates cell according to the weighted value calculated in this optional embodiment.And sentence Whether the load of disconnected candidate's compensation cell overloads thresholding, if judging the load of candidate's compensation cell not less than load thresholding, Then determine that the candidate cell is compensation cell.Otherwise, then through the above way one or mode two meet condition to searching in adjacent cell Candidate compensation cell as compensation cell.

If not finding the compensation cell for meeting condition in above-mentioned adjacent cell, this compensation to fault cells will be unsuccessfully tying Beam.Now, it is " forbidding switching " and the side of " fault cells are arranged to forbid accessing " to use the switch attribute of modification adjacent area Method carries out self-healing compensation, with reduce because fault cells cannot self-healing and caused by influence.

In another optional implementation method, the response message that base station where can also receiving compensation cell sends, wherein, response Compensation failure cause is carried in message, wherein, compensating the reason for failing includes following at least one：

Reason one：Compensation cell has been in compensating coefficient.

If a compensation cell does single compensation in synchronization most multipotency, i.e. be only capable of at any time to a fault cells Compensate.If the message that the base station of compensation cell base station where synchronization receives multiple fault cells sends, and all Same cell is needed to compensate, then this compensation will be unsuccessfully terminating.

Therefore, to the compensation cell determined in above-mentioned steps be made whether be compensate cell judgement, if it is determined that go out compensating small Area has been in compensating coefficient, then the message eNB CONFIGURATION FAILURE that the base station where receiving compensation cell sends, And failure reason value is returned for Compensation Fail.Wherein, compensation cell refers to the compensation cell currently quilt in compensating coefficient Compensation cell as other fault cells.

In addition, the message that base station where if fault cells receive compensation cell is replied is compensation failed message, the failure is small Area will use changes adjacent area switch attribute for the method for " forbidding switching " and " fault cells are arranged to forbid accessing " is carried out certainly More compensate.

Reason two：The radio-frequency antenna for compensating cell is non-electric regulating intelligent antenna.

If it is determined that the radio-frequency antenna for going out to compensate cell is non-electric regulating intelligent antenna, then what the base station where receiving compensation cell sent disappears Breath eNB CONFIGURATION FAILURE, and failure reason value is returned for Compensation Fail, it is this time small to failure The compensation in area will be unsuccessfully terminating.

In addition, if all the radio-frequency antenna of compensation cell is non-electric regulating intelligent antenna, the fault cells will be using modification adjacent area Switch attribute carries out self-healing compensation for the method for " forbidding switching " and " fault cells are arranged to forbid accessing ".

Reason three：Compensate the coverage adjustment failure of cell.

If compensating the coverage adjustment failure of cell, for example, the aerial angle adjustment failure of compensation cell, then receive compensation small The message eNB CONFIGURATION FAILURE that base station where area sends, and return to failure reason value and be Compensation Fail, this time will be unsuccessfully terminating to the compensation of fault cells.

Fig. 2 is the flowchart 2 of the compensation method of cell self-healing according to embodiments of the present invention, as shown in Fig. 2 the flow includes Following steps：

Step S202, receives the message that base station where fault cells sends, wherein, carried for compensating fault cells in message Compensation cell information.

Fault cells are compensated by step S204 using compensation cell.

By above-mentioned steps, base station where compensation cell receives the message that base station where fault cells sends, according to disappearing for receiving The coverage of increase compensation cell is ceased, realization is compensated to fault cells, as a result of compensation cell to failure Cell is compensated, and is solved in the prior art because cell breaks down or cell fault recovery unsuccessfully causes the cell footprint There is the problem of blind area in domain, and the technique effect of Consumer's Experience sense is improve so as to reach.

Receive the message that base station where fault cells sends can have many kinds, in an optional implementation method, in pair event Before barrier cell carries out self-healing compensation, the message eNB CONFIGURATION that base station where fault cells sends can be received UPDATE, the message is the existing message of 3GPP agreements.And to the Served of eNB CONFIGURATION UPDATE messages Cells To Delete message bodies increase the information (Compensation Cells Information) of compensation cell.Where compensation cell After base station receives the eNB CONFIGURATION UPDATE messages, can be according to Compensation Cells Information Cell Global Identifier ECGI in message searches corresponding compensation cell, and fault cells are entered using corresponding compensation cell Row compensation.

Compensation cell method that fault cells are compensated by many kinds, in an optional implementation method, can be by increasing The coverage of large compensation cell realizes the compensation to fault cells.

There can be many kinds by way of the coverage for increasing compensation cell realizes that compensation cell is compensated to fault cells, In an optional implementation method, can send a command to mend by using the baseband processing unit BBU where compensation cell Radio frequency remoto module RRU where repaying cell, wherein, the angle of declination for indicating RRU to turn the antenna of compensation cell down is instructed, Then, Downtilt is turned down according to instruction by RRU.

In this optional embodiment, can by the baseband processing unit where compensating cell (Base Band Unit, referred to as BBU) sent to the radio frequency remoto module (Radio Frequency Resource Unit, referred to as RRU) where compensation cell The order of Downtilt is adjusted, wherein, the antenna is electric regulating intelligent antenna.After the regulating command is received, preserve current RRU antennas parameter, then RRU will automatically adjust angle of declination angle by instruction, increased with this compensation cell covering Scope, so as to reach the purpose in the region of compensation fault cells covering, wherein, angular adjustment amplitude can be imitative by operation data Data after very are configured.After the angle of declination of antenna is adjusted successfully, RRU can also will reply electricity and adjust angle of declination to adjust successfully Message is to BBU.

In an optional embodiment, before being compensated to fault cells using compensation cell, wait can also be started and mended Timer is repaid, wherein, in the case where timer expiry to be compensated is waited, perform fault cells are compensated using compensation cell The step of.

In this optional embodiment, if base station where compensation cell receives configuration update message (eNB CONFIGURATION UPDATE), the timer to be compensated such as can be started, for example, where by compensating cell BBU (Base Band Unit) starts the timer to be compensated such as this.If waiting timer expiry to be compensated, the BBU will be to right Radio frequency remoto module RRU where the compensation cell answered sends and turns the instruction of Downtilt down and increase the covering model of compensation cell Enclose.

In another optional embodiment, starting etc. after timer to be compensated, judge before compensation timer expiry whether Receive the cancellation compensation instruction that base station where fault cells sends；The base where fault cells are received before compensating timer expiry In the case that the cancellation compensation for sending of standing is indicated, the step of being compensated to fault cells using compensation cell is cancelled.

If before compensation waiting timer time-out, new message eNB CONFIGURATION UPDATE are have received, and should Message body (Served Cells To Add) is carried in message.The compensation of the Neighbour Information in the message body is small Carried in area's information and cancel compensation instruction (Deactive Compensation Indication), compensation cell is according to (Neighbour Information) the Cell Global Identifier ECGI in message matches oneself, is indicated after the match is successful and in the presence of compensation is cancelled In the case of (Deactive Compensation Indication), compensation cell will stop compensation waiting timer, and this time failure is small Area need not compensate.

In another optional implementation method, when being compensated to fault cells using compensation cell, can also judge Whether compensation cell meets compensation condition, then, in the case where judging that compensation cell meets compensation condition, performs and uses benefit The step of repaying cell fault cells are compensated, for example, being realized to fault cells by increasing the coverage of compensation cell Compensation, wherein, compensation condition includes following at least one：

Condition one：Compensation cell is not in compensating coefficient.

If a compensation cell does single compensation in synchronization most multipotency, i.e. be only capable of at any time to a fault cells Compensate.

Can be made whether it has been the judgement that compensates cell to compensation cell, if it is determined that going out to compensate cell is not in compensating coefficient, then Fault cells are compensated using the compensation cell.Wherein, compensation cell refers to the compensation cell currently quilt in compensating coefficient Compensation cell as other fault cells.

Condition two：The radio-frequency antenna for compensating cell is electric regulating intelligent antenna.

Whether the radio-frequency antenna that can be determined that compensation cell is electric regulating intelligent antenna, if it is determined that the radio-frequency antenna for going out to compensate cell is electricity Regulating intelligent antenna, then compensated using the compensation cell to fault cells.

Condition three：The coverage for compensating cell is successfully adjusted.

The radio-frequency antenna for determining compensation cell is electric regulating intelligent antenna, then the BBU transmissions where compensating cell turn electricity down and adjust intelligence RRU where the order of Downtilt to compensation cell.After RRU receives the order, the regulation to angle of declination is realized, if Angle of declination is adjusted successfully, then the coverage for compensating cell is successfully adjusted, you can fault cells are entered with using compensation cell Row compensation.

In another optional implementation method, when judging that compensation cell is unsatisfactory for any of the above-described compensation condition, can also be to event The reason for base station where barrier cell provides compensation failure, the base station where sending response message to fault cells, wherein, response disappears Compensation failure cause is carried in breath.

In this alternative embodiment, if judge that compensation cell is unsatisfactory for above-mentioned compensation condition, the base station where compensation cell can To send base station of the eNB CONFIGURATION FAILURE message to where fault cells, can also be to fault cells institute It is Compensation Fail to return to failure reason value in base station, this time will be unsuccessfully terminating to the compensation of fault cells.
