It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The poor optimizing cells of CSFB perception rest on always drive test cell level in the prior art, not to non-drive test cell into Row CSFB perception difference optimization is thrown the net network mainly due to CSFB across two, currently without the poor cell of specific index judgement CSFB perception.

In the embodiment of the present invention, in order to excavate the poor cell of CSFB perception, poor cell is perceived by core net and drive test CSFB, Existing net index is associated, determines the evaluation index for influencing CSFB perception factors, to evaluation index requirement cannot be reached The poor cell of CSFB perception, carries out CSFB optimizations.

It is obtained according to statistics, the cell of about 70% LTE network is since core net factor causes CSFB perception poor, separately Outer about 30% cell may be since (Global System for Mobile communication, the whole world are mobile logical by GSM Letter system) CSFB perception caused by the factors such as network or core net factor, the adjacent areas CSFB leakage is poor.

The poor cell of CSFB perception would generally be related to two networks：LTE and GSM network.It analyzes, relates generally to from signaling process RRC percent of call completeds, CSFB run succeeded rate, LTE paging success rates, GSM paging success rates, GSM percent of call completeds etc., and such index is ordered Entitled signaling process feature.It is analyzed from network profound cause, is mainly concerned with GSM/ TD SDMAs TD-SCDMA (G/T) weak covering accounting, G/T matter differences accounting, border cell etc., network coverage feature is named as by such index.

Fig. 1 shows the schematic stream of the poor cell determining method of circuit domain dropping perception according to an embodiment of the invention Cheng Tu.As shown in Figure 1, this approach includes the following steps.

110, the corresponding CSFB call informations of network type based on target network screen CSFB to be evaluated in target network The Target cell of perception.

Wherein, for the cell in LTE network and GSM network, not all cell is required to carry out CSFB perception Evaluation, so the Target cell of CSFB to be evaluated perception in network is determined in this step first, for CSFB need not be carried out The cell for perceiving evaluation will not then carry out CSFB perception evaluations.It is filtered out by CSFB call informations in the embodiment of the present invention The Target cell of CSFB to be evaluated perception in target network.

It should be noted that the poor cell of CSFB perception would generally be related to LTE network and GSM network, in heterogeneous networks Cell, using different evaluation methods.

120, the evaluation index for taking evaluation goal cell CSFB to perceive is looked into according to network type.

Wherein, the poor cell of CSFB perception would generally be related to LTE network and GSM network, and different network types is used Different evaluation indexes perceives to evaluate the CSFB of cell, so, after determining network type, needs foundation network type to look into and take The evaluation index of evaluation goal cell CSFB perception corresponding with network type.

130, obtain the evaluation index relevant parameter of Target cell.

Wherein, it after step 120 is looked into and takes evaluation index, in order to evaluate Target cell, needs to obtain index first Relevant parameter, i.e., the parameter of the user's evaluation Target cell CSFB perception involved in evaluation index.

140, evaluation index relevant parameter is unsatisfactory for evaluation index, determines that Target cell is the cell of CSFB perception differences.

Wherein, after the evaluation index relevant parameter for obtaining Target cell, the parameter of acquisition is carried out based on evaluation index Judge, judges whether the parameter obtained disclosure satisfy that evaluation index.It, can be with if the parameter obtained disclosure satisfy that evaluation index It is the poor cell of CSFB perception to determine Target cell not；If the parameter obtained disclosure satisfy that evaluation index, mesh can be determined Mark the cell that cell is CSFB perception differences.

The Target cell for determining CSFB perception to be evaluated in the embodiment of the present invention first, is then based on evaluation index and mesh Target cell can be carried out CSFB perception evaluations by marking the evaluation index relevant parameter of cell, and then can determine that CSFB is perceived The cell of difference.In this way, the parameter of CSFB perception evaluations of the embodiment of the present invention can directly acquire, without being adopted by drive test Collection, ensure that the accuracy of the data for evaluation, and then improve the accuracy rate for the cell for determining CSFB perception differences, improve to The service quality at family.

It is understood that in embodiments of the present invention, the network type of target network can be LTE network, at this time CSFB call informations include CSFB context requests number in preset time period.Fig. 2 is the electricity according to further embodiment of this invention The schematic flow chart of the poor cell determining method of road domain dropping perception.As shown in Fig. 2, the network type of target network is LTE When network, step 110 can be executed specifically as following steps.

111, obtain the CSFB context request numbers of each cell within a preset period of time in target network.

Wherein, the cell under being covered for LTE network, due to carrying out CSFB perception to the more cell of the CSFB numbers of calls Evaluation is just significant, so small to screen target according to CSFB context requests number in preset time period in the embodiment of the present invention Area.So needing first to obtain the CSFB context requests time of each cell within a preset period of time in target network in this step Number.

112, the cell that CSFB context request numbers are more than to preset value is determined as Target cell.

It wherein, can in obtaining target network after the CSFB context request numbers of cell within a preset period of time The CSFB context request numbers of acquisition to be compared with preset value, CSFB context request numbers are more than preset value Cell is determined as Target cell.Preset time period and the size of preset value can be arranged according to practical application scene, for example, default Period is set as 1 hour, and preset value is set as 100 times.

Since CSFB context requests number can reflect the CSFB numbers of calls, so passing through in the embodiment of the present invention The size of CSFB context request numbers screens Target cell, so as to accurately to it is necessary to carry out in LTE network The cell of CSFB perception evaluations screens.

Can also include step after step 140 it is understood that in Fig. 1, Fig. 2 or shown in Fig. 3 method 150, according to the ungratified evaluation index of cell institute of CSFB perception differences, the cell of optimization CSFB perception differences.

Wherein, when step 140 determines CSFB perception difference cells, by judging that the evaluation index correlation of Target cell is joined Whether number meets evaluation index to determine the cell of CSFB perception differences, so for the cell for the CSFB perception differences determined, it can To know its ungratified evaluation index of institute, and then small poor to CSFB perception of these ungratified evaluation indexes of institute can be directed to Area optimizes.

Specifically, when the ungratified evaluation index of cell institute of CSFB perception differences include in preset time period CSFB execute at Power be more than run succeeded rate pre-determined threshold when, can according to CSFB prepare flow, CSFB relevant configured parameter or base station therefore Hinder the cell of state optimization CSFB perception differences.

For example, the CSFB rates that run succeeded are default no more than the rate that runs succeeded within a preset period of time for the cell of CSFB perception differences Thresholding, then CSFB perception difference cell be unsatisfactory for this evaluation index, may determine that at this time CSFB perception difference cell because flow rush CSFB caused by prominent prepares whether the frequency of failure is more than 0 and accounts for principal element.If the CSFB caused by flow conflicts prepares to lose Number is lost more than 0 and accounts for principal element, then can determine that CSFB perception difference is to prepare flow by CSFB to cause, can further sentence Disconnected is to be caused by X2 switchings or caused by TAU (Tracking Area Update, tracing section updating), and then can carry out excellent Change；If the CSFB caused by flow conflicts prepares the frequency of failure and is not more than 0, the relevant configured parameter of CSFB can be judged again It is whether suitable, for example, verifying whether configure suitable GSM frequency points, check that cell CSFB is fallen after rise to whether the priority of GSM sets Set mistake etc..If it is determined that causing CSFB perception poor because the relevant configured parameter of CSFB is improper, then can further judge It is that, frequency point group improper by CSFB switchgear distributions is not configured or Linqu is not configured to cause, and then can optimizes；If it is determined that It is not to cause CSFB perception poor because the relevant configured parameter of CSFB is improper, then can further judges base station fault state, such as Fruit base station fault state is failure, then can be determined that CSFB perception differences are caused by base station fault.

Alternatively,

When the ungratified evaluation index of cell institute of CSFB perception differences includes RRC connection reconstructions request time in preset time period When number is less than number pre-determined threshold, perceived according to the relevant configured parameter of RRC, the covering state of the poor cell of CSFB perception, CSFB The cell of the adjacent area setting optimization CSFB perception differences of the poor cell of disturbance state or CSFB perception of poor cell.

For example, RRC connection reconstructions request number of times is less than the pre- gating of number to the cell of CSFB perception differences within a preset period of time It limits, then the cell of CSFB perception difference is unsatisfactory for this evaluation index, may determine that the correlation of the cell RRC of CSFB perception differences is matched at this time Whether suitable parameter is set, for example, TAC (Trace Area Code, Tracking Area Code), PCI (Physical Cell Identifier, Physical Cell Identifier), working frequency range and other relevant configured parameters it is whether suitable.If the correlation of RRC is matched It sets that parameter is improper, then can determine that CSFB perception difference is caused by the relevant configured parameter of RRC, and then it can be to these parameters It optimizes；If the relevant configured parameter of RRC is suitable, can judge again the poor cell of CSFB perception covering state whether be Weak covering (whether the weak covering sampled point accounting of cell is more than 50%).If it is determined that because weak covering causes CSFB perception poor, then may be used To be optimized to weak covering problem；If it is determined that then can further being judged because weak covering causes CSFB perception poor Whether the disturbance state of the poor cell of CSFB perception is that there are interference, for example, judging MRR (Measurement Result Recording indicates the performance measurement function that is counted based on measurement report result) high interference accounting whether be more than 30% or Whether it is more than -100dBm per the interference of RB average noises, if MRR high interference accountings are more than 30% or big per RB average noise interference In -100dBm, then it can be determined that disturbance state is to exist to interfere.If the disturbance state of the poor cell of CSFB perception is to exist to do It disturbs, then can be determined that CSFB perception differences are caused by interference, and then optimize；If the disturbance state of the poor cell of CSFB perception is There is no interference, then may determine that whether the adjacent area setting of the poor cell of CSFB perception is suitable, for example, judging that S1 switches that (or X2 is cut Changing) whether more than 50 times, whether S1 switchings (or X2 switchings) success rate is less than 80% to number of attempt.If it is determined that CSFB perception is poor The adjacent area setting of cell is improper, then is optimized to adjacent area setting, for example, optimization neighboring BS relationship setting.

Alternatively,

It is small according to CSFB perception differences when RRC is created as power less than power pre-determined threshold is created as in preset time period The resource allocation status in area, the transmission RRC reasons of the poor cell of CSFB perception or UE response status optimization CSFB perceive the small of difference Area.

For example, CSFB perception difference cell within a preset period of time RRC be created as power be less than be created as power preset door It limits, then the cell of CSFB perception difference is unsatisfactory for this evaluation index, may determine that the resource allocation shape of the poor cell of CSFB perception at this time Whether state is suitable, is optimized if improper.The resource allocation status of the poor cell of CSFB perception whether include properly：Whether Resource allocation fails and causes RRC connections foundation failure, RRC success rates low, if SRS resource distribution fails and RRC is caused to connect Connect foundation failure, RRC success rates it is low, if PUCCH (PhVsical Uplink Control Channel, physical uplink link Control channel) resource allocation failure and cause RRC connections establish unsuccessfully, RRC success rates it is low.Specifically, resource allocation is unsuccessfully wrapped It includes the local resource distribution failure of CSFB perception differences and causes RRC connections to establish the frequency of failure and be more than 10 times, RRC success rates are less than 90%, optimal way can be to check whether resource is sufficient, including maximum top numbers of users, transmission, PRB (physical Resource block, Physical Resource Block) etc.；The distribution of Sounding Reference Signal SRS resource includes unsuccessfully CSFB perception differences The distribution of cell SRS resource fails and causes RRC connections to establish the frequency of failure and be more than 10 times, the cell RRC successes of CSFB perception differences Rate is less than 90%, and optimal way can be to check SRS bandwidth, configuration instruction, configuration mode, the non-response NACK of SRS responses ACK/ Whether setting is reasonable etc.；Cell PUCCH resource distribution of the PUCCH resource distribution unsuccessfully including CSFB perception differences fails and causes RRC connections are established the frequency of failure and are more than 10 times；The cell RRC success rates of CSFB perception differences are less than 90%, and optimal way can be Check whether PUCCH channels relative parameters setting is reasonable, whether the configuration of CQI resource block RB numbers reasonable etc..If CSFB perception is poor The resource allocation status of cell is suitable, then can further judge the transmission RRC reasons of the poor cell of CSFB perception and optimize. The transmission RRC reasons of the poor cell of CSFB perception include：The cell of CSFB perception differences sends RRC connections and refuses Connection Reject message causes RRC success rates low, and RRC connection request Connection Request message discarding caused by flow control causes RRC success rates are low, and RRC Connection Reject message is sent caused by flow control causes RRC success rates low.Further may be used also To judge whether the cell of CSFB perception differences causes RRC connections foundation unsuccessfully to cause RRC success rates low since UE is unresponsive, such as Fruit causes RRC connections foundation unsuccessfully to cause RRC success rates low since UE is unresponsive, can adjust down link public channel power, examines Look into whether covering problem and interference problem etc..

Specifically, when the ungratified evaluation index of cell institute of CSFB perception differences include in preset time period paging acknowledgment lose When abandoning number more than predetermined number, according to the cell of the paging amount optimization CSFB perception differences in preset time period.

For example, in preset time period paging acknowledgment abandon number be more than predetermined number show paging congestion, according to it is default when Between paging amount in section the reason of judging paging congestion.If paging amount is excessive to lead to congestion (paging acknowledgment reception number ＞ 100 Ten thousand/hour), then parameter optimization can be carried out, optimal way includes that pagingNb (of paging block is occurred in each radio frames Number) it is tuned up on the basis of existing, or coordinate the adjustment RP Radio Paging control channel unit CCE degree of polymerization (tuning up), paging weight again Again number (turning down), user equipment (UE) monitor the DRX (Discontinuous Reception, discontinuous reception) of paging occasion Cycle period (tuning up) etc.；Cell splitting can also be carried out, paging congested cell is split into two new cells；It can also weigh The new boundaries planning TAC, which is divided under the smaller TAC of other paging amounts.If paging amount is too small to lead to congestion, can To be optimized by wireless environment, hardware device etc..

Alternatively,

When the ungratified evaluation index of cell institute of CSFB perception differences includes the low SINR sampled points of uplink in preset time period When accounting is less than in accounting pre-determined threshold and/or preset time period averagely CQI less than default average value, according to CSFB perception differences Cell corresponds to equipment failure state, the covering state of the poor cell of CSFB perception, the disturbance state of the poor cell of CSFB perception, CSFB senses Know the cell of the parameter configuration optimization CSFB perception differences of poor cell.

For example, it includes failure or non-failure, the poor cell of CSFB perception that the cell of CSFB perception differences, which corresponds to equipment failure state, Covering state include CSFB perception differences the weak covering of cell, the parameter configuration of the poor cell of CSFB perception includes：It verifies and saves control ginseng Whether number meets the settings of setting specification and PCI etc., and whether reasonable and AF panel parameter opens.In such cases, It can also judge that the cell of CSFB perception differences with the presence or absence of interference problem, engineering problem, and then optimizes, engineering problem can be with It is reversed including antenna feeder, isolation between antennas is inadequate, site location is unreasonable etc..

Alternatively,

When the ungratified evaluation index of cell institute of CSFB perception differences includes weak covering sampled point accounting in preset time period When less than preset ratio, the hardware device malfunction of poor cell, the traffic congestion of the poor cell of CSFB perception are perceived according to CSFB The neighboring BS relationship state optimization CSFB perception of state, the network parameter setting of the poor cell of CSFB perception or the poor cell of CSFB perception The cell of difference.

For example, if the hardware device malfunction of the poor cell of CSFB perception is hardware device failure, it can be to hardware Equipment optimizes；If the traffic congestion state of the poor cell of CSFB perception is traffic congestion, can by shunting, dilatation into Row optimization；If it is unreasonable that the network parameter of the poor cell of CSFB perception is set as network parameter setting, it is excellent parameter can be carried out Change；If the neighboring BS relationship state of the poor cell of CSFB perception is that neighboring BS relationship setting is unreasonable, Neighborhood Optimization can be carried out. In such cases, it can also be moved by website, site is planned, new site optimizes.
