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.

Fig. 1 is a flowchart of a cell network coverage evaluation method according to an embodiment of the present invention. As shown in fig. 1, the method includes:

step S101, acquiring the quantity of RAUs and the quantity of backflow data of a 2G cell in a preset time range, wherein the quantity of the RAUs is the quantity of the RAUs switched to the 2G cell from any 4G cell;

with the construction and development of LTE networks, in order to meet the requirements of customers, the construction of 4G cells is being popularized in the coverage area of the original 2G cell, and the coverage state of 4G signals, especially in indoor environments, becomes very complicated due to the characteristics of large space transmission consumption, poor penetration capability and the like of 4G high-frequency band signals. The use of large data to evaluate the 4G signal coverage status is a very efficient and feasible solution.

The embodiment of the invention firstly sends a data acquisition request to a big data center of a mobile network server, and requires to acquire the RAU quantity and the backflow data quantity of the 2G cell within a preset time range. The preset time range can be one day, one week or one month, and the specific time range can be determined according to the needs of the user. The RAU number is the number of RAU information switched from any 4G cell to the 2G cell, which is extracted from the routing area update information RAU information sent by the client due to cell switching. And the backflow data volume is the data volume of the 4G client for performing data transmission by using the 2G network of the 2G cell, that is, when the device supports the 4G network, due to poor 4G signals and other reasons, data that cannot be sent in the 4G network is transmitted by using the 2G network instead.

And step S102, evaluating the coverage condition of the 4G signals in the coverage area of the 2G cell according to the RAU quantity and the backflow data quantity.

And evaluating the 4G signal condition and the use amount of the client in the range of the 2G cell according to the acquired RAU number and the backflow data amount of the 2G cell in the preset time range. The higher the value of the RAU number is, the more unstable the 4G signal in the coverage area of the present 2G cell is, the easier the handover from the 4G cell to the 2G cell is, and the larger the amount of the backflow data is, the more the client terminal after the handover from the 4G cell to the 2G cell uses the network of the 2G cell, and the client terminal does not switch back to the 4G cell in time, which also indicates that the coverage area of the 4G signal in the coverage area of the 2G cell is bad. In addition, the larger the RAU number and the backflow data volume, the higher the number of clients and the higher the use frequency of the 2G cell can be reflected. Of course, these data are only used as some reference for optimizing the 4G signal of the subsequent 2G cell, and how to use the data can be determined according to the actual situation. For example, some thresholds may be set to screen 2G cells to select 2G cells that are in urgent need of subsequent optimization.

According to the embodiment of the invention, the quality of the 4G signal coverage condition in the coverage range of the 2G cell is evaluated by analyzing the RAU quantity and the backflow data quantity of the collected 2G cell, so that the evaluation is faster and more accurate, and a large amount of labor and material cost for the on-site test is saved.

Fig. 2 is a flowchart of another cell network coverage evaluation method according to an embodiment of the present invention. As shown in fig. 2, the method includes:

step S101, acquiring the RAU quantity and the backflow data quantity of a 2G cell in a preset time range, wherein the RAU quantity is the quantity of the RAU switched to the 2G cell from any 4G cell;

step S101 is the same as the method of the above embodiment, and is not described again here.

Step S103, acquiring MR coverage of a 4G cell in the time range, wherein the 4G cell is in the coverage of the 2G cell;

for those cases where at least one 4G cell is built in the coverage area of the 2G cell, the 4G signal usage condition of the 4G cell can be further evaluated not only for the 4G signal evaluation in the coverage area of the 2G cell, but also by using information related to the 4G cell, such as MR coverage, so that the subsequent 4G signal optimization scheme can be more accurately located to the specific 4G cell.

Further, the acquiring the MR coverage of the 4G cell in the time range specifically includes:

acquiring MR data uploaded by the 4G cell in the time range, wherein the MR data at least comprises a 4G signal strength value;

and calculating the MR coverage rate of the 4G cell, wherein the MR coverage rate is the number of MR data with 4G signal intensity values larger than a preset intensity threshold value compared with the number of all MR data.

When the client uses the 4G network of the 4G cell, the physical layer of the client periodically reports the measurement result report MR data for system operation and maintenance and system operation state observation. The MR data includes data representing 4G signal strength values, such as RSRP, RS _ SINR, and the like.

And then according to a preset intensity threshold, if the intensity of the 4G signal is greater than the intensity threshold, the 4G signal at the moment is considered to meet the requirement, otherwise, the 4G signal is considered to be poor. The ratio of the number of MR data satisfying the requirement of the 4G signal to the total number of the collected MR data is the MR coverage rate. Taking RSRP and RS _ SINR as examples, wherein the preset strength thresholds are-110 dBm and 0dB respectively, then

MR data amount with MR coverage (RSRP > -110dBm and RS _ SINR > -0 dB)/total MR data amount × 100%.

And step S104, evaluating the coverage condition of the 4G signals in the 4G coverage cell range according to the RAU number, the backflow data volume and the MR coverage rate.

At this time, three items of data related to the 4G cell are obtained, including: the RAU quantity and the backflow data quantity of a 2G cell, and the MR coverage rate of the 4G cell, wherein the 4G cell is in the coverage range of the 2G cell. And analyzing the RAU data, the backflow data volume and the MR coverage rate to obtain the 4G signal condition in the 4G cell coverage range. The analysis of the three data items is mainly used for making a reference for 4G signal optimization of the 4G cell, and a specific evaluation method can be designed according to actual needs.

According to the embodiment of the invention, the 4G signal condition in the coverage range of the 4G cell can be evaluated by collecting the MR coverage rate of the 4G cell and combining the RAU data and the backflow data volume of the 2G cell related to the 4G cell, so that the 4G signal condition can be evaluated more quickly and accurately, and a large amount of manpower and material resources for getting to the station are saved.

Based on the above embodiment, further, the method further includes:

acquiring a corresponding relation table of the 2G cell and the 4G cell;

in the corresponding relation table, if at least one 4G cell exists in the coverage area of the 2G cell, whether the longitude and latitude distances between the 2G cell and the corresponding 4G cell meet a preset distance range or not is checked, and the unsatisfied 4G cells are removed.

Before 4G signal evaluation is performed on a 2G cell or a 4G cell, a clear understanding of the corresponding relationship between the 2G cell and the 4G cell is required.

According to the previous construction plan, the corresponding relation table of the 2G cell and the 4G cell can be obtained firstly. It can be seen in the correspondence table that the construction situation of the 4G cell in the coverage area of each 2G cell can be divided into three types: 1, no 4G cell is constructed; 2, only one 4G cell is constructed; and 3, constructing a plurality of 4G cells. According to the longitude and latitude points of each 2G cell and each 4G cell, the longitude and latitude distance between the 2G cell and each 4G cell in the coverage area of the 2G cell can be calculated, if the obtained longitude and latitude distance exceeds a preset distance range, for example, 50m, the 4G cell is considered not to be in the coverage area of the 2G cell, and therefore the 4G cell can be removed from the table. The finally obtained correspondence table can divide the 2G cell into two types, namely a 4G cell and a non-4G cell.

For 4G cells, especially 2G cells constructed with a plurality of 4G cells, 4G signals within the coverage area of each 4G cell can be further evaluated according to the MR coverage rate of each 4G cell. And the 2G cell without the 4G cell can only evaluate the number of clients and the utilization rate of the 2G cell according to the RAU number and the backflow data volume of the 2G cell so as to determine whether the 4G cell needs to be established in the 2G cell.

According to the embodiment of the invention, whether the 4G signal in the coverage area of the 4G cell is further evaluated is judged by acquiring the corresponding relation between the 2G cell and the 4G cell, so that the 4G signal condition can be evaluated more quickly and accurately, and a large amount of manpower and material resources for getting on the station are saved.

Based on the foregoing embodiment, further, the evaluating the coverage of the 4G signal in the 2G cell range according to the RAU number, the backflow data amount, and the MR coverage includes:

screening out 4G cells needing 4G signal optimization according to preset conditions, wherein the preset conditions specifically meet the following conditions: the MR coverage rate is within a preset MR coverage rate threshold range, the RAU quantity is within a preset RAU threshold range, and the backflow data volume is within a preset backflow data volume threshold range.

According to the three parameter values of the 4G cell obtained in the above embodiment: there are many methods for evaluating 4G signals within the coverage area of the 4G cell, based on the MR coverage, the RAU number, and the flow back data amount.

For example, one solution provided in this embodiment is to perform the screening directly according to the preset conditions. Respectively presetting threshold ranges of the three parameter values: MR coverage threshold range, e.g. below 90%, RAU threshold range, e.g. above 10000 times and backflow data amount threshold range, e.g. above 300M. When the MR coverage rate is within a preset MR coverage rate threshold range, the RAU number is within a preset RAU threshold range and the backflow data volume is within a preset backflow data volume threshold range, the 4G cell can be reported so as to perform subsequent 4G signal optimization operation. For example, if the MR coverage of a certain 4G cell is 85%, the number of RAUs is 12000, and the volume of backflow data is 500M, it may be determined that 4G signal optimization is urgently needed for the 4G cell. Of course, the values of these conditions may be changed in practical applications, and the conditions to be satisfied may also be changed, for example, only one threshold range of the three parameter values may be satisfied to determine that optimization is needed.

In order to further refine the 4G signal state analysis of the 4G cells, the evaluation results of the 4G signal state may be ranked, and the three parameter values are respectively scored and weighted.

For example, the scoring criteria for the three parameter values are preset as follows:

RAU threshold range	MR coverage threshold range	Threshold range of backflow data volume	Score of
				>10000	<70％	>500M	5
10000～5001	70％～80.1％	500～201M	3
				5000～1000	80％～90％	200～100M	1
<1000	>90％	<100M	0

After the RAU score, the MR score and the backflow data volume score of the 4G cell are obtained respectively, according to a preset weight ratio, for example, the RAU score is 50%, the MR score is 30%, and the backflow data volume score is 20%, the 4G signal score of the 4G cell is calculated as follows:

4G signal score ═ RAU score 50% + MR score 30% + backflow data score 20%,

and sequencing each 4G cell according to the 4G signal score obtained by each 4G cell, and obtaining the 4G cell which needs 4G signal optimization most.

The numerical values and classifications of the above embodiments are only examples and are not intended to be limiting in practical applications.

According to the embodiment of the invention, the 4G cell needing 4G signal optimization can be obtained by screening or calculating the obtained 4G cell related parameters, so that the 4G signal condition can be evaluated more quickly and accurately, and a large amount of manpower and material resources for getting on the station are saved.

Based on the foregoing embodiment, further, the acquiring the RAU number of the 2G cell in the preset time range specifically includes:

collecting RAU information in each client signaling in the time range, wherein the RAU information at least comprises a cell identifier after switching;

if the RAU information is judged to be switched from the 4G cell to the 2G cell, recording the RAU information at this time;

and counting the RAU number of the 2G cell, wherein the RAU number is the number corresponding to the cell identifier and the 2G cell in the recorded RAU information.

When a client performs inter-cell handover between different cells due to movement or poor network signals of an original cell, a signaling is sent, wherein the signaling includes routing area update information RAU information of the client, and the RAU information at least includes cell types, cell identifiers and RAU information generation time before and after routing area handover. The signaling may be stored in data documents of network interfaces, such as the iups and Gb interfaces.

The mobile network server collects RAU information in each client signaling of the RAU information generation time within the time range from a data bill of a network interface. For the time range, for example, taking a week as an example, since traffic models on weekdays and weekends have different performances in most scenes, for example, in a cell where an office or a shopping mall is located, the number and the use conditions of clients have great difference between weekdays and weekends, when the RAU information is extracted, the weekdays and the weekends need to be separately extracted and evaluated. In addition, fluctuations of RAU information amount caused by holidays or emergencies, such as competitions or concerts, are avoided as much as possible, and the time periods can be directly eliminated in the selected time range, or the time ranges of the time periods can be avoided, or a new evaluation scheme can be established according to the special scenes.

And meanwhile, the RAU information collected is screened according to the requirement, and only the RAU information switched from the 4G cell to the 2G cell is reserved according to the cell types before and after switching in the RAU information.

Then, according to the switched cell identifiers in the RAU information, respectively counting the number of the RAU information corresponding to the cell identifier and the 2G cell in the reserved RAU information, thereby obtaining the 2G cell RAU number.

The embodiment of the invention screens the RAU information of the collected client to obtain the number of RAUs of the 2G cell in the preset time range, thereby increasing the dimensionality for evaluating the quality of the 4G signal, ensuring faster and more accurate evaluation and saving a large amount of labor and material cost for the on-site test.

Fig. 3 is a schematic structural diagram of a cell network coverage evaluation apparatus according to an embodiment of the present invention. As shown in fig. 3, includes an acquisition unit 11 and an evaluation unit 12, wherein:

the acquiring unit 11 is configured to acquire the RAU number and the backflow data amount of a 2G cell within a preset time range, where the RAU number is the number of RAUs that are handed over from any 4G cell to the 2G cell; and the evaluation unit 12 is configured to evaluate a coverage situation of the 4G signal within the 2G cell range according to the RAU number and the backflow data amount. Specifically, the method comprises the following steps:

the acquiring unit 11 first acquires the RAU number and the backflow data amount of the 2G cell within a preset time range from the mobile network server. The preset time range can be one day, one week or one month, and the specific time range can be determined according to the needs of the user. The RAU number is the RAU number for switching any 4G cell to the 2G cell, which is extracted from the RAU information sent by the client. And the backflow data volume is the data volume of the 4G client for data transmission by using the 2G network of the 2G cell.

The acquired RAU number and the backflow data amount acquired by the acquisition unit 11 are sent to the evaluation unit 12, so that the evaluation unit 12 can evaluate the 4G signal condition and the usage amount of the client in the 2G cell range according to the RAU number and the backflow data amount of the 2G cell in the preset time range. The higher the value of the RAU number is, the more unstable the 4G signal in the coverage area of the present 2G cell is, the easier the handover from the 4G cell to the 2G cell is, and the larger the amount of the backflow data is, the more the client terminal after the handover from the 4G cell to the 2G cell uses the network of the 2G cell, and the client terminal does not switch back to the 4G cell in time, which also indicates that the coverage area of the 4G signal in the coverage area of the 2G cell is bad. In addition, the larger the RAU number and the backflow data volume, the higher the number of clients and the higher the use frequency of the 2G cell can be reflected. Of course, these data are only used as some reference for optimizing the 4G signal of the subsequent 2G cell, and how to use the data can be determined according to the actual situation.

The apparatus provided in the embodiment of the present invention is configured to execute the method, and the functions of the apparatus refer to the method embodiment specifically, and detailed method flows thereof are not described herein again.

In the embodiment of the present invention, the evaluation unit 12 analyzes the RAU number and the backflow data amount of the 2G cell collected by the acquisition unit 11 to evaluate the quality of the 4G signal coverage in the coverage area of the 2G cell, so that the evaluation is faster and more accurate, and a large amount of labor and material costs for the station-entering test are saved.

Based on the foregoing embodiment, further, the obtaining unit is further configured to obtain an MR coverage rate of a 4G cell in the time range, where the 4G cell is in a coverage area of the 2G cell; accordingly, the number of the first and second electrodes,

and the evaluation unit is further configured to evaluate the coverage of the 4G signal in the 2G cell range according to the RAU number, the backflow data amount, and the MR coverage.

For those cases that at least one 4G cell is built in the coverage area of the 2G cell, not only the 4G signal within the coverage area of the 2G cell can be evaluated, but also the information related to the 4G cell, such as the MR coverage rate, can be acquired by the acquisition unit, so as to further evaluate the use condition of the 4G signal in the 4G cell in the evaluation unit, and thus, the subsequent 4G signal optimization scheme can be more accurately positioned to the specific 4G cell.

and calculating the MR coverage rate of the 4G cell, wherein the MR coverage rate is the ratio of the number of MR data with 4G signal intensity values larger than a preset intensity threshold value to the number of all MR data.

And then according to a preset intensity threshold, if the intensity of the 4G signal is greater than the intensity threshold, the 4G signal at the moment is considered to meet the requirement, otherwise, the 4G signal is considered to be poor. The ratio of the number of MR data satisfying the requirement of the 4G signal to the total number of the collected MR data is the MR coverage rate.

At this time, the evaluation unit receives three items of data related to the 4G cell, including: the RAU quantity and the backflow data quantity of a 2G cell, and the MR coverage rate of the 4G cell, wherein the 4G cell is in the coverage range of the 2G cell. And analyzing the RAU data, the backflow data volume and the MR coverage rate to obtain the 4G signal condition in the 4G cell coverage range.

According to the embodiment of the invention, the acquisition unit is used for collecting the MR coverage rate of the 4G cell, so that the evaluation unit can evaluate the 4G signal condition in the coverage range of the 4G cell by combining the RAU data and the backflow data volume of the 2G cell related to the 4G cell, thereby evaluating the 4G signal condition more quickly and accurately and saving a great amount of manpower and material resources for getting to the station.

Based on the foregoing embodiment, further, the obtaining unit is further configured to obtain a correspondence table between the 2G cell and the 4G cell; and in the corresponding relation table, if at least one 4G cell exists in the coverage area of the 2G cell, checking whether the longitude and latitude distances between the 2G cell and the corresponding 4G cell meet a preset distance range, and rejecting the unsatisfied 4G cells.

The obtaining unit may obtain a correspondence table between the 2G cell and the 4G cell according to a previous construction plan, and the construction condition of the 4G cell in each 2G cell may be seen in the correspondence table. According to the longitude and latitude points of each 2G cell and each 4G cell, the longitude and latitude distance between the 2G cell and each 4G cell in the coverage area of the 2G cell can be calculated, if the obtained longitude and latitude distance exceeds a preset distance range, for example, 50m, the 4G cell is considered not to be in the coverage area of the 2G cell, and therefore the 4G cell can be removed from the table. The finally obtained correspondence table can divide the 2G cell into two types, namely a 4G cell and a non-4G cell.

For 4G cells, especially 2G cells constructed with a plurality of 4G cells, the acquisition unit may further acquire MR coverage of each 4G cell, so that the evaluation unit may further evaluate 4G signals within the coverage of each 4G cell. For a 2G cell without a 4G cell, the evaluation unit can only evaluate the number of clients and the usage rate of the 2G cell according to the RAU number and the backflow data amount of the 2G cell, so as to determine whether to add the 4G cell in the 2G cell.

The apparatus provided in the embodiment of the present invention is configured to execute the method, and the functions of the apparatus refer to the method embodiment specifically, and the specific method flow is not described herein again.

According to the embodiment of the invention, the corresponding relation between the 2G cell and the 4G cell is acquired by the acquisition unit to judge whether the evaluation unit further evaluates the 4G signal in the coverage area of the 4G cell or not, so that the 4G signal condition can be evaluated more quickly and accurately, and a large amount of manpower and material resources for getting on the station are saved.

screening out 4G cells needing 4G signal optimization according to preset conditions, wherein the preset conditions are specifically that: the MR coverage rate is within a preset MR coverage rate threshold range, the RAU quantity is within a preset RAU threshold range, and the backflow data volume is within a preset backflow data volume threshold range.

According to the three parameter values of the 4G cell received by the evaluation unit in the above embodiment: there are many methods for evaluating 4G signals within the coverage area of the 4G cell, based on the MR coverage, the RAU number, and the flow back data amount.

For example, one solution provided in this embodiment is to perform the screening directly according to the preset conditions. Respectively presetting threshold ranges of the three parameter values: MR coverage threshold range, e.g. below 90%, RAU threshold range, e.g. above 10000 times and backflow data amount threshold range, e.g. above 300M. When the MR coverage rate is within a preset MR coverage rate threshold range, the RAU number is within a preset RAU threshold range and the backflow data volume is within a preset backflow data volume threshold range, the 4G cell can be reported so as to perform subsequent 4G signal optimization operation. Of course, the values of these conditions may be changed in practical applications, and the conditions to be satisfied may also be changed, for example, only one threshold range of the three parameter values may be satisfied to determine that optimization is needed.

In the embodiment of the invention, the evaluation unit screens or calculates the received 4G cell related parameters to obtain the 4G cell needing 4G signal optimization, so that the 4G signal condition can be evaluated more quickly and accurately, and a large amount of manpower and material resources for uploading are saved.

The mobile network server collects RAU information in each client signaling of the RAU information generation time within the time range from a data bill of a network interface. For the time range, for example, one week, since traffic models on weekdays and weekends have different performances in most scenes, it is necessary to separately extract and evaluate the weekdays and weekends when extracting RAU information. In addition, fluctuations of RAU information amount caused by holidays or emergencies, such as competitions or concerts, are avoided as much as possible, and the time periods can be directly eliminated in the selected time range, or the time ranges of the time periods can be avoided, or a new evaluation scheme can be established according to the special scenes.

In the screening process, the mobile network server may first screen according to preset conditions, and then send the screened 2G cell RAU number to the obtaining unit, or the obtaining unit may automatically screen according to specific preset conditions after receiving all RAU information sent by the server. The specific use process can be set according to actual conditions.

According to the embodiment of the invention, the RAU number of the 2G cell in the preset time range is obtained by screening the collected RAU information of the client, so that the dimensionality of the evaluation unit for evaluating the quality of the 4G signal is increased, the evaluation is faster and more accurate, and a large amount of labor and material cost of the on-site test is saved.
