Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

In the prior art, CSFB perception difference cell optimization always stays at a drive test cell level, CSFB perception difference optimization is not carried out on a non-drive test cell, and the CSFB crosses two networks, so that no clear index is provided for judging the CSFB perception difference cell at present.

In the embodiment of the invention, in order to excavate the CSFB perception difference cell, the current network index is correlated through the core network and the drive test CSFB perception difference cell, the evaluation index influencing the CSFB perception factor is determined, and CSFB optimization is carried out on the CSFB perception difference cell which can not meet the evaluation index requirement.

According to statistics, about 70% of cells of the LTE network are poor CSFB perception due to core network factors, and about 30% of cells may be poor CSFB perception due to GSM (Global System for Mobile communication) network or core network factors, CSFB neighbor missing and other factors.

A CSFB-aware bad cell would typically involve two networks: LTE and GSM networks. From the analysis of the signaling flow, the method mainly relates to RRC call completing rate, CSFB execution success rate, LTE paging success rate, GSM call completing rate and the like, and the indexes are named as signaling flow characteristics. From the analysis of network deep-level reasons, the method mainly relates to GSM/time division synchronous code division multiple access TD-SCDMA (G/T) weak coverage ratio, G/T poor quality ratio, boundary cells and the like, and the indexes are named as network coverage characteristics.

Fig. 1 shows a schematic flow chart of a method for determining a circuit switched fallback aware-poor cell according to an embodiment of the present invention. As shown in fig. 1, the method includes the following steps.

And 110, screening the target cell to be evaluated for CSFB perception in the target network based on the CSFB call information corresponding to the network type of the target network.

For cells in an LTE network and a GSM network, not all cells need to be subjected to CSFB aware evaluation, so in this step, a target cell to be subjected to CSFB awareness evaluation in the network is first determined, and for cells that do not need to be subjected to CSFB aware evaluation, CSFB aware evaluation is not performed. In the embodiment of the invention, the target cell to be evaluated and sensed by the CSFB in the target network is screened out through the CSFB call information.

It should be noted that the CSFB-aware poor cell generally relates to the LTE network and the GSM network, and different evaluation methods are adopted for cells in different networks.

And 120, searching and obtaining the evaluation index perceived by the CSFB of the evaluation target cell according to the network type.

The CSFB perception difference cell generally relates to an LTE network and a GSM network, and different evaluation indexes are used for evaluating CSFB perception of the cell for different network types, so after the network type is determined, the evaluation index of CSFB perception of an evaluation target cell corresponding to the network type needs to be searched according to the network type.

And 130, acquiring the evaluation index related parameters of the target cell.

After the evaluation index is retrieved in step 120, in order to evaluate the target cell, it is necessary to first obtain an index-related parameter, that is, a parameter perceived by the user to evaluate the target cell CSFB, which is related in the evaluation index.

140, determining that the target cell is the cell with poor CSFB perception if the evaluation index related parameters do not meet the evaluation index.

After obtaining the evaluation index related parameters of the target cell, judging the obtained parameters based on the evaluation indexes, and judging whether the obtained parameters can meet the evaluation indexes. If the obtained parameters can meet the evaluation indexes, the target cell can be determined not to be a cell with poor CSFB perception; if the obtained parameters can meet the evaluation index, the target cell can be determined to be a cell with poor CSFB perception.

In the embodiment of the invention, the target cell to be evaluated for CSFB perception is determined, and then the CSFB perception evaluation can be carried out on the target cell based on the evaluation index and the evaluation index related parameter of the target cell, so that the cell with poor CSFB perception can be determined. Therefore, the parameters of the CSFB perception evaluation in the embodiment of the invention can be directly obtained without the need of drive test acquisition, so that the accuracy of the data for evaluation is ensured, the accuracy of determining the cell with poor CSFB perception is improved, and the service quality of the user is improved.

It can be understood that, in the embodiment of the present invention, the network type of the target network may be an LTE network, and the CSFB call information includes the number of CSFB context requests within a preset time period. Fig. 2 is a schematic flow chart of a method for determining a circuit switched fallback aware-poor cell according to another embodiment of the present invention. As shown in fig. 2, when the network type of the target network is an LTE network, step 110 may be specifically performed as the following step.

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

For the cells under the coverage of the LTE network, since it is significant to perform CSFB aware evaluation on the cells with a large number of CSFB calls, the target cells are screened according to the number of CSFB context requests within a preset time period in the embodiment of the present invention. Therefore, in this step, the CSFB context request times of each cell in the target network within the preset time period need to be obtained first.

And 112, determining the cell with the CSFB context request times larger than the preset value as a target cell.

After the number of CSFB context requests of the cell in the target network within the preset time period is obtained, the obtained number of CSFB context requests may be compared with a preset value, and a cell with the CSFB context request number greater than the preset value is determined as a target cell. The preset time period and the preset value can be set according to the actual application scenario, for example, the preset time period is set to 1 hour, and the preset value is set to 100 times.

Because the number of CSFB context requests can reflect the number of CSFB calls, the target cell is screened according to the number of CSFB context requests, so that cells which need to be subjected to CSFB perception evaluation in an LTE network can be accurately screened.

It should be noted that the data processing procedure of the steps 120-140 shown in fig. 2 is substantially the same as the data processing procedure of the steps 120-140 shown in fig. 1, and is not repeated herein.

It can be understood that, in the embodiment of the present invention, the network type of the target network may be an LTE network, and the evaluation index includes the first signaling flow characteristic and the first network coverage characteristic.

The first signalling flow characteristic comprises any one or more of: the CSFB execution success rate in the preset time period is greater than an execution success rate preset threshold, the number of times of RRC (Radio resource control) connection reestablishment requests in the preset time period is less than a number preset threshold, and the RRC establishment success rate in the preset time period is greater than an establishment success rate preset threshold.

According to the signaling flows of the CSFB calling party and the called party, the first signaling flow characteristics mainly relate to: a CSFB execution success rate, RRC connection reestablishment request times and an RRC establishment success rate. Therefore, in the embodiment of the invention, an execution success rate preset threshold, a frequency preset threshold and an establishment success rate preset threshold are set, and the perception of the target cell is evaluated based on the set thresholds.

The success rate of CSFB execution within a preset time period represents: the RRC connection release times triggered by the CSFB within the preset time period/(the CSFB initial context setup request times within the preset time period + the CSFB context modification request times within the preset time period), that is, the ratio of the RRC connection release times triggered by the CSFB within the preset time period to the sum of the CSFB initial context setup request times within the preset time period and the CSFB context modification request times within the preset time period. When the CSFB execution success rate is greater than the execution success rate preset threshold within the preset time period, the target cell is an evaluation index meeting the first signaling flow characteristic; and when the CSFB execution success rate is less than or equal to the execution success rate preset threshold within the preset time period, the target cell is an evaluation index which does not meet the first signaling flow characteristic.

When the times of the RRC connection reestablishment request in the preset time period are smaller than a preset threshold of the times, the target cell is an evaluation index meeting the first signaling flow characteristic; and when the times of the RRC connection reestablishment request in the preset time period are more than or equal to the times preset threshold, indicating that the target cell is an evaluation index which does not meet the first signaling process characteristic.

When the RRC establishment success rate is greater than the establishment success rate preset threshold within a preset time period, the target cell is an evaluation index meeting the first signaling flow characteristic; and when the RRC establishment success rate is less than or equal to the establishment success rate preset threshold within the preset time period, the target cell is an evaluation index which does not meet the first signaling flow characteristic.

In the embodiment of the present invention, the preset time period, the execution success rate preset threshold, the number of times preset threshold, and the establishment success rate preset threshold may be set according to the actual application scenario, for example, the preset time period is set to 1 hour, the execution success rate preset threshold is set to 95%, the number of times preset threshold is set to 80, and the establishment success rate preset threshold is set to 90%.

The first network coverage feature comprises any one or more of: the Ratio of SINR (Signal to Interference plus Noise Ratio) sampling points in a preset time period is less than a Ratio preset threshold, an average CQI (Channel Quality Indicator) in the preset time period is greater than a preset average value, the Ratio of weakly covered sampling points in the preset time period is less than a preset Ratio, and the number of discarded paging records in the preset time period is less than a preset number.

The first network coverage feature mainly considers the aspects of poor quality, weak coverage, boundary position updating and the like. Therefore, the CSFB perception evaluation is carried out on the target cell according to the SINR sampling point ratio, the average CQI, the weak coverage sampling point ratio and the number of discarded paging records.

When the occupation ratio of the SINR sampling points in the preset time period is smaller than a occupation ratio preset threshold, representing that the target cell is an evaluation index meeting the first network coverage characteristic; and when the SINR sampling point occupation ratio is greater than or equal to the occupation ratio preset threshold in the preset time period, indicating that the target cell does not meet the evaluation index of the first network coverage characteristic.

When the average CQI in a preset time period is larger than a preset average value, the target cell is an evaluation index meeting the first network coverage characteristic; and when the average CQI in the preset time period is less than or equal to the preset average value, the target cell is represented as an evaluation index which does not meet the first network coverage characteristic.

When the proportion of the weak coverage sampling points in the preset time period is smaller than the preset proportion, the target cell is represented as an evaluation index meeting the first network coverage characteristic; and when the proportion of the weak coverage sampling points in the preset time period is greater than or equal to the preset proportion, the target cell is represented as an evaluation index which does not meet the first network coverage characteristic.

When the number of discarded paging records in a preset time period is less than the preset number, the target cell is an evaluation index meeting the first network coverage characteristic; and when the number of discarded paging records in the preset time period is greater than or equal to the preset number, indicating that the target cell does not meet the evaluation index of the first network coverage characteristic.

In the embodiment of the present invention, the preset time period, the ratio preset threshold, the preset average value, the preset ratio and the preset number may be set according to an actual application scenario, for example, the preset time period is set to 1 hour, the preset number is set to 10, the ratio preset threshold is set to 20%, the preset average value is set to 5, and the preset ratio is set to 50%.

In the embodiment of the invention, as for the first signaling flow characteristic comprising various evaluation indexes, the target cell which does not meet any one of the evaluation indexes can be evaluated as the evaluation index which does not meet the first signaling flow characteristic; similarly, for the first network coverage characteristic including various evaluation indexes, the target cell which does not satisfy any of the evaluation indexes can be evaluated as not satisfying the evaluation index of the first network coverage characteristic. And under the condition that the target cell simultaneously evaluates that the target cell does not meet the evaluation index of the first signaling flow characteristic and the evaluation index of the first network coverage characteristic, the target cell is a CSFB perception difference cell.

It can be understood that, in the embodiment of the present invention, the network type of the target network may be a GSM network, and the CSFB call information includes traffic volume of each line in a preset time period, a total sampling point of downlink signal quality in the preset time period, and CSFB context request times of an LTE station corresponding to the GSM network in the preset time period. Fig. 3 is a schematic flow chart of a method for determining a cs fallback aware poor cell according to still another embodiment of the present invention. As shown in fig. 3, when the network type of the target network is a GSM network, step 110 may be further specifically executed as the following step.

113, obtaining the traffic volume of each line in a preset time period, the total sampling point of the downlink signal quality in the preset time period, and the number of CSFB context requests of the LTE station corresponding to the GSM network in the preset time period.

For the cells covered by the GSM network, because CSFB aware evaluation is only meaningful for the cells with a large number of CSFB calls, in the embodiment of the present invention, the target cell is screened according to the traffic volume of each line in the preset time period, the total sampling point of the downlink signal quality in the preset time period, and the number of CSFB context requests of the LTE station corresponding to the GSM network in the preset time period. Therefore, in this step, the three parameters of each cell in the target network in the preset time period need to be obtained first.

The LTE station corresponding to the GSM network represents the LTE station which is within a preset distance range from the GSM network station and has an included angle smaller than a preset angle. The preset angle and the preset distance may be set according to an actual application scenario, for example, the preset distance is set to 500 meters, and the preset angle is set to 120 degrees.

And 114, determining the cell with the telephone traffic of each line greater than the telephone traffic preset threshold, the total sampling point of the downlink signal quality greater than the sampling point preset threshold and the CSFB context request times greater than the times preset threshold as a target cell.

After the parameters are obtained in step 113, the target cell may be screened according to the obtained parameters. The preset time period, the preset traffic threshold, the preset sampling point threshold and the preset times threshold may be set according to the actual application scenario, for example, the preset time period is set to 1 hour, the preset traffic threshold is set to 0.1erl, the preset sampling point threshold is set to 100, and the preset times threshold is set to 100.

It should be noted that the data processing procedure of the steps 120-140 shown in fig. 3 is substantially the same as the data processing procedure of the steps 120-140 shown in fig. 1, and is not repeated herein.

It can be understood that, in the embodiment of the present invention, the network type of the target network may be an LTE network, and the evaluation index includes the second signaling flow characteristic and the second network coverage characteristic.

The second signalling flow characteristic comprises any one or more of: the allocation success rate of a Traffic Channel (TCH) in a preset time period is greater than a preset TCH allocation success rate threshold, the allocation success rate of a Stand-Alone Dedicated Control Channel (SDCCH) in the preset time period is greater than the preset SDCCH allocation success rate threshold, and the paging overflow ratio in the preset time period is less than the preset overflow ratio threshold.

According to the signaling flows of the CSFB calling party and the called party, the second signaling flow is characterized by mainly relating to: TCH distribution success rate, SDCCH distribution success rate and paging overflow proportion. Therefore, in the embodiment of the invention, a TCH allocation success rate preset threshold, an SDCCH allocation success rate preset threshold and an overflow ratio preset threshold are set, and the perception of the target cell is evaluated based on the set threshold values.

The TCH allocation success rate can be calculated by dividing the TCH allocation success rate by the TCH allocation attempt rate (without handover) and multiplying by 100%. When the TCH distribution success rate is greater than the TCH distribution success rate preset threshold within the preset time period, the target cell is an evaluation index meeting the second signaling flow characteristic; and when the TCH distribution success rate is less than or equal to the TCH distribution success rate preset threshold in the preset time period, the target cell is an evaluation index which does not meet the characteristics of the second signaling flow.

The SD allocation success rate may be calculated by dividing the number of successful SDCCH setups by the total number of call attempts multiplied by 100%. When the SDCCH allocation success rate is greater than the SDCCH allocation success rate preset threshold within the preset time period, the target cell is an evaluation index meeting the second signaling flow characteristic; and when the SDCCH allocation success rate is less than or equal to the SDCCH allocation success rate preset threshold in the preset time period, the evaluation index which does not meet the second signaling flow characteristic is represented.

When the paging overflow proportion in the preset time period is smaller than the overflow proportion preset threshold, the target cell is an evaluation index meeting the second signaling flow characteristic; and when the paging overflow ratio is greater than or equal to the overflow ratio preset threshold in the preset time period, indicating that the target cell is an evaluation index which does not meet the second signaling flow characteristic.

In the embodiment of the present invention, the preset time period, the preset threshold of TCH allocation success rate, the preset threshold of SDCCH allocation success rate, and the preset threshold of overflow ratio may be set according to an actual application scenario, for example, the preset time period is set to 1 hour, the preset threshold of TCH allocation success rate is set to 80%, the preset threshold of SDCCH allocation success rate is set to 80%, and the preset threshold of overflow ratio is set to 0.1%.

The second network coverage feature mainly considers the aspects of poor quality, weak coverage, boundary position updating and the like. The second network coverage characteristic comprises any one or more of: the overflow frequency of the SDCCH in a preset time period is smaller than a preset threshold of the overflow frequency of the SDCCH, the overflow frequency of the paging in the preset time period is smaller than a preset threshold of the overflow frequency of the paging, the overflow frequency of the AGCH (Access Grant Channel) in the preset time period is smaller than a preset threshold of the overflow frequency of the AGCH, the overflow frequency of the voice Channel in the preset time period is smaller than a preset threshold of the overflow frequency of the voice Channel, the ratio of the downlink 0-5-level call quality in the preset time period is larger than a preset threshold of the ratio of the quality, and the coverage rate of the measurement report in the preset time period is larger than a preset threshold of the coverage rate.

When the overflow frequency of the SDCCH is smaller than the preset threshold of the overflow frequency of the SDCCH in the preset time period, the target cell is an evaluation index meeting the coverage characteristics of the second network; and when the overflow frequency of the SDCCH is more than or equal to the preset threshold of the overflow frequency of the SDCCH in the preset time period, the target cell is an evaluation index which does not meet the coverage characteristics of the second network.

When the paging overflow frequency in the preset time period is smaller than the paging overflow frequency preset threshold, the target cell is an evaluation index meeting the second network coverage characteristic; and when the paging overflow frequency in the preset time period is less than the paging overflow frequency preset threshold, indicating that the target cell does not meet the evaluation index of the second network coverage characteristic.

When the number of AGCH overflow times in a preset time period is smaller than a preset threshold of the number of AGCH overflow times, the target cell is an evaluation index meeting the second network coverage characteristic; and when the AGCH overflow frequency is more than or equal to the AGCH overflow frequency preset threshold in the preset time period, indicating that the target cell is an evaluation index which does not meet the second network coverage characteristic.

When the overflow frequency of the voice channel in the preset time period is smaller than the preset threshold of the overflow frequency of the voice channel, the target cell is represented as an evaluation index meeting the coverage characteristics of the second network; and when the overflow frequency of the voice channel in the preset time period is smaller than the preset threshold of the overflow frequency of the voice channel, indicating that the target cell is an evaluation index which does not meet the coverage characteristics of the second network.

When the downlink 0-5 level call quality ratio is greater than the quality ratio preset threshold within the preset time period, the target cell is an evaluation index meeting the second network coverage characteristic; and when the downlink 0-5 level call quality ratio is greater than the quality ratio preset threshold in the preset time period, indicating that the target cell does not meet the evaluation index of the second network coverage characteristic.

When the downlink coverage rate of the measurement report in a preset time period is greater than a preset threshold of the coverage rate, the target cell is an evaluation index meeting the coverage characteristics of the second network; and when the downlink coverage rate of the measurement report in the preset time period is greater than the preset threshold of the coverage rate, indicating that the target cell is an evaluation index which does not meet the coverage characteristics of the second network.

In the embodiment of the present invention, the preset time period, the preset threshold for SDCCH overflow times, the preset threshold for paging overflow times, the preset threshold for AGCH overflow times, the preset threshold for voice channel overflow times, the preset threshold for quality occupancy, and the preset threshold for coverage rate may be set according to the actual application scenario, for example, the preset time period is set to 1 hour, the preset threshold for SDCCH overflow times is set to 50, the preset threshold for paging overflow times is set to 50, the preset threshold for AGCH overflow times is set to 50, the preset threshold for voice channel overflow times is set to 50, the preset threshold for quality occupancy is set to 75%, and the preset threshold for coverage rate is set to 60%.

It should be noted that, in the embodiment of the present invention, the number of times of voice channel overflow in the preset time period does not include the case of switching.

In the embodiment of the invention, as for the second signaling flow characteristics comprising various evaluation indexes, the target cell which does not meet any one of the evaluation indexes can be evaluated as the evaluation index which does not meet the second signaling flow characteristics; similarly, for the second network coverage characteristic including various evaluation indexes, the target cell not satisfying any of the evaluation indexes can be evaluated as not satisfying the evaluation index of the second network coverage characteristic. And under the condition that the target cell simultaneously evaluates that the target cell does not meet the evaluation index of the second signaling flow characteristic and the evaluation index of the second network coverage characteristic, the target cell is the CSFB perception difference cell.

It is understood that in the method shown in fig. 1, fig. 2 or fig. 3, after step 140, step 150 may be further included to optimize the CSFB poorly perceived cell according to the evaluation index that is not satisfied by the CSFB poorly perceived cell.

When the CSFB perception difference cell is determined in step 140, the cell with the CSFB perception difference is determined by determining whether the evaluation index related parameter of the target cell meets the evaluation index, so that the determined cell with the CSFB perception difference can know the evaluation index which is not met, and the cell with the CSFB perception difference can be optimized according to the evaluation index which is not met.

Specifically, when the evaluation index that is not satisfied by the cell with poor CSFB sensing includes that the CSFB execution success rate is greater than the execution success rate preset threshold within the preset time period, the cell with poor CSFB sensing may be optimized according to the CSFB preparation procedure, the relevant configuration parameters of the CSFB, or the base station fault state.

For example, if the CSFB execution success rate of the cell with poor CSFB sensing is not greater than the execution success rate preset threshold within the preset time period, the cell with poor CSFB sensing does not meet the evaluation index, and at this time, it may be determined whether the CSFB preparation failure frequency of the cell with poor CSFB sensing due to the flow conflict is greater than 0 and accounts for a main factor. If the number of times of CSFB preparation failure due to the flow conflict is greater than 0 and accounts for a main factor, it may be determined that the CSFB perception difference is caused by the CSFB preparation flow, and it may be further determined whether the CSFB perception difference is caused by X2 handover or TAU (Tracking Area Update), so that optimization may be performed; if the number of CSFB preparation failures due to the process conflict is not greater than 0, it may be determined whether the relevant configuration parameters of the CSFB are appropriate, for example, whether an appropriate GSM frequency point is configured, whether the priority of the CSFB falling back to GSM in the cell is set incorrectly, and the like. If the CSFB perception is poor due to the fact that relevant configuration parameters of the CSFB are not appropriate, further judgment can be made that the CSFB is caused by the fact that the CSFB switch is not appropriate in configuration, the frequency point group is not configured or the circuit breaker 26384is not configured, and then optimization can be carried out; if the CSFB perception is judged not to be poor due to the fact that the relevant configuration parameters of the CSFB are not appropriate, the fault state of the base station can be further judged, and if the fault state of the base station is a fault, the CSFB perception poor is judged to be caused by the fault of the base station.

Alternatively, the first and second electrodes may be,

and when the evaluation index which is not satisfied by the cell with poor CSFB perception includes that the number of times of RRC connection reestablishment requests in a preset time period is less than a preset threshold of times, setting the cell with optimized CSFB perception difference according to related configuration parameters of RRC, the coverage state of the cell with poor CSFB perception, the interference state of the cell with poor CSFB perception, or the adjacent cell of the cell with poor CSFB perception.

For example, if the number of times of RRC connection reestablishment requests in a Cell with poor CSFB sensing is smaller than a preset threshold of times within a preset time period, the Cell with poor CSFB sensing does not satisfy the evaluation index, and at this time, it may be determined whether relevant configuration parameters of the Cell RRC with poor CSFB sensing are appropriate, for example, whether TAC (Trace Area Code), PCI (Physical Cell Identifier), operating frequency band, and other relevant configuration parameters are appropriate. If relevant configuration parameters of the RRC are not appropriate, the CSFB perception difference can be determined to be caused by the relevant configuration parameters of the RRC, and then the parameters can be optimized; if the relevant configuration parameters of the RRC are suitable, it may be determined whether the coverage state of the CSFB perceived poor cell is weak coverage (whether the sampling point occupation ratio of the cell weak coverage is greater than 50%). If the CSFB perception is poor due to weak coverage, the problem of weak coverage can be optimized; if it is determined that the CSFB perception is not poor due to weak coverage, it may be further determined whether an interference state of the CSFB perception poor cell is interference, for example, whether an MRR (Measurement Result Recording, which indicates a performance Measurement function that performs statistics based on Measurement report results) high interference occupancy is greater than 30% or an average noise interference per RB is greater than-100 dBm, and if the MRR high interference occupancy is greater than 30% or the average noise interference per RB is greater than-100 dBm, it may be determined that the interference state is interference. If the interference state of the CSFB perception difference cell is the interference, the CSFB perception difference can be judged to be caused by the interference, and then optimization is carried out; if the interference state of the CSFB perception poor cell is that there is no interference, it may be determined whether the neighboring cell setting of the CSFB perception poor cell is appropriate, for example, whether the number of attempts of S1 handover (or X2 handover) is greater than 50 and the success rate of S1 handover (or X2 handover) is less than 80%. And if the neighbor cell setting of the CSFB perception poor cell is judged to be not appropriate, optimizing the neighbor cell setting, for example, optimizing the neighbor cell relation setting.

Alternatively, the first and second electrodes may be,

and when the RRC establishment success rate is smaller than the establishment success rate preset threshold within a preset time period, optimizing the cell with poor CSFB perception according to the resource allocation state of the cell with poor CSFB perception, the RRC sending reason of the cell with poor CSFB perception or the UE response state.

For example, the RRC establishment success rate of the cell with poor CSFB sensing is smaller than the establishment success rate preset threshold in the preset time period, and the cell with poor CSFB sensing does not meet the evaluation index, and at this time, it may be determined whether the resource allocation state of the cell with poor CSFB sensing is appropriate, and if not, the cell with poor CSFB sensing is optimized. Whether the resource allocation status of the CSFB-aware bad cell is appropriate includes: whether the RRC connection establishment fails due to a resource allocation failure and the RRC success rate is low, whether the RRC connection establishment fails due to a SRS resource allocation failure and the RRC success rate is low, and whether the RRC connection establishment fails due to a PUCCH (physical Uplink Control Channel) resource allocation failure and the RRC success rate is low. Specifically, the resource allocation failure includes that the number of times of failure of RRC connection establishment caused by a cell resource allocation failure with poor CSFB sensing is greater than 10, the RRC success rate is less than 90%, and the optimization mode may be to check whether resources are sufficient, including the maximum top user number, transmission, PRB (physical resource block), and the like; the channel sounding reference signal SRS resource allocation failure comprises that the RRC connection establishment failure times are more than 10 times due to CSFB perception poor cell SRS resource allocation failure, the CSFB perception poor cell RRC success rate is less than 90%, and the optimization mode can be checking whether SRS bandwidth, configuration indication, configuration mode, SRS response ACK/non-response NACK setting are reasonable or not; the PUCCH resource allocation failure comprises that the number of times of RRC connection establishment failure is more than 10 due to the failure of CSFB perception poor cell PUCCH resource allocation; the success rate of cell RRC with poor CSFB perception is less than 90%, and the optimization mode can be to check whether the PUCCH channel related parameter setting is reasonable, whether the RB number configuration of the CQI resource block is reasonable, and the like. If the resource allocation state of the CSFB perception poor cell is appropriate, the RRC sending reason of the CSFB perception poor cell can be further judged and optimized. The reason for sending the RRC in the CSFB aware bad cell includes: the cell with poor CSFB perception sends an RRC Connection rejection message to cause low RRC success rate, the RRC Connection Request message caused by flow control is discarded to cause low RRC success rate, and the RRC Connection Reject message caused by flow control causes low RRC success rate. And further, whether the RRC success rate is low due to the RRC connection establishment failure caused by the UE non-response of the cell with poor CSFB perception can be judged, and if the RRC success rate is low due to the RRC connection establishment failure caused by the UE non-response, the power of the downlink common channel can be adjusted, whether coverage problems and interference problems exist can be checked, and the like.

Specifically, when the evaluation index that the cell with poor CSFB sensing does not meet includes that the number of discarded paging records in the preset time period is greater than the preset number, the cell with poor CSFB sensing is optimized according to the paging amount in the preset time period.

For example, the number of discarded paging records in the preset time period is greater than the preset number, which indicates paging congestion, and the reason for the paging congestion is determined according to the paging volume in the preset time period. If the paging volume is too large and causes congestion (the number of received paging records is more than 100 ten thousand per hour), parameter optimization can be performed, wherein the optimization mode comprises that pagingNb (the number of paging blocks appearing in each wireless frame) is increased on the existing basis, or the polymerization degree (increase) of CCE (control channel element) of broadcast paging control, the paging repetition times (decrease) and the DRX (Discontinuous Reception) cycle (increase) of the paging occasion monitored by user equipment UE are matched and adjusted; the method can also carry out cell splitting to split the paging congestion cell into two new cells; and the TAC boundary can be planned again, and the cell is divided into other TACs with smaller paging quantity. If the amount of paging is too small, resulting in congestion, optimization may be performed by the wireless environment, hardware devices, etc.

Alternatively, the first and second electrodes may be,

and when the evaluation index which is not satisfied by the cell with poor CSFB perception includes that the ratio of uplink low SINR sampling points in a preset time period is less than a preset threshold and/or the average CQI in the preset time period is less than a preset average value, configuring and optimizing the cell with poor CSFB perception according to the equipment fault state corresponding to the cell with poor CSFB perception, the coverage state of the cell with poor CSFB perception, the interference state of the cell with poor CSFB perception and the parameter of the cell with poor CSFB perception.

For example, the failure state of the corresponding device of the CSFB-perceived poor cell includes failure or no failure, the coverage state of the CSFB-perceived poor cell includes weak coverage of the CSFB-perceived poor cell, and the parameter configuration of the CSFB-perceived poor cell includes: and checking whether the provincial control parameters meet the setting specifications, whether the settings such as PCI are reasonable, and whether the interference suppression parameters are started. Under the condition, whether the interference problem and the engineering problem exist in the cell with poor CSFB perception can be judged, and then optimization is carried out, wherein the engineering problem can comprise antenna feedback reverse connection, insufficient antenna isolation, unreasonable site position and the like.

Alternatively, the first and second electrodes may be,

and when the unsatisfied evaluation index of the CSFB perception difference cell comprises that the weak coverage sampling point occupation ratio in the preset time period is smaller than the preset proportion, optimizing the CSFB perception difference cell according to the hardware equipment fault state of the CSFB perception difference cell, the service congestion state of the CSFB perception difference cell, the network parameter setting of the CSFB perception difference cell or the adjacent cell relation state of the CSFB perception difference cell.

For example, if the hardware device failure state of the CSFB aware-bad cell is a hardware device failure, the hardware device may be optimized; if the service congestion state of the CSFB perception difference cell is service congestion, optimization can be carried out through shunting and capacity expansion; if the network parameter setting of the CSFB perception difference cell is unreasonable, the parameter optimization can be carried out; and if the neighbor relation state of the CSFB perception difference cell is unreasonable in neighbor relation setting, neighbor optimization can be performed. In this case, optimization can be performed by site relocation, site planning, and site creation.
