Description

Circuit domain fallback frequency point configuration method, device, electronic equipment and storage medium

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device, electronic device, and storage medium for configuring circuit domain fallback frequency points.

Background technique

Circuit Switched Fallback (CSFB), as a voice service bearer solution on LTE network, is applicable to overlapping coverage scenarios of TD-LTE and 2G/3G wireless network. The network sends the GSM frequency points through the redirection command (RRC Connection Release), and the terminal reads the GSM frequency points in sequence, finds a suitable GSM cell to reside in and performs CS services.

The existing LTE cell GSM fallback frequency point addition scheme mainly relies on GSI (Geographic Information System, geographic information system) related planning software to carry out distance-based GSM frequency point planning, and then add them one by one regardless of priority.

There is also a GSM frequency configuration solution based on a measurement report (Measurement Report, MR). For example, a Chinese patent application document with the application number "201510461451.X" discloses a method for optimizing the configuration of CSFB frequency points based on measurement report data. The method includes the following steps: extracting and collecting GSM RSSI and RSRP data in the measurement report periodically reported by the terminal; combining the GSM RSSI data collected by each sector with the average RSRP of the LTE service cell, and performing linear coefficient weighted average processing on the ratio of MR sampling points , and calculate the linear weighted score of each frequency point coefficient; according to the order of the weighted score calculated by BCCH from large to small, optimize the allocation of CSFB fallback frequency points.

The above-mentioned existing circuit domain fallback frequency point addition schemes all have certain limitations, which are reflected in:

Although the GIS planning method can add most of the suitable neighbors, considering the complexity of the wireless network, adding GSM frequency points one by one regardless of priority may miss the GSM frequency point with the strongest signal, and the guide will not fall. optimal neighborhood.

Although the construction of GSM fallback frequency points based on MR data can avoid the problem of unconfigured strongest GSM frequency points, the method based on MR data depends on the integrity and accuracy of MR data collection, and the data reported by different terminals varies greatly. It is necessary to periodically report GSM frequency point measurement information, which will also cause terminal power consumption problems.

FIG. 1 shows a schematic flowchart of a method for configuring circuit domain fallback frequency points provided by an embodiment of the present invention.

As shown in FIG. 1, the circuit domain fallback frequency point configuration method provided by the embodiment of the present invention specifically includes the following steps:

S11. Obtain the information of the GSM cell co-located with the current LTE cell, the historical handover data of the GSM cell co-sited with the current LTE cell, the historical handover data of the LTE cell, and the existing circuit domain fallback frequency point information of the LTE cell;

The embodiment of the present invention collects relevant data of the current LTE cell through the network management system, mainly collecting the information of the GSM cell co-sited with the current LTE cell, the historical handover data of the GSM cell co-sited with the current LTE cell, the historical handover data of the LTE cell, and the LTE cell Existing circuit domain fallback frequency point information.

Among them, the information of the GSM cell co-stationed with the current LTE cell (hereinafter referred to as the co-stationed GSM) mainly collects the station name, the cell information of different sectors under the same base station, the latitude and longitude and the azimuth angle, specifically, the co-station with the current LTE cell The principles include the same station name, the distance between the stations is less than 50 meters, and the absolute value of the azimuth angle difference between the cells is less than 30 degrees.

The historical handover data of the co-sited GSM mainly includes the point-to-point handover data of the co-sited GSM cell within a specified period, such as statistics on the handover information of the co-sited GSM cell to another GSM cell (target GSM cell) within a week, the number of handovers, and the number of target GSM cells. The weight of GSM cell switching times.

The collection of historical handover data of LTE cells is mainly the point-to-point handover data of LTE cells within a specified period, including target LTE cells switched to within a specified period (for example, one week), the number of handovers, and the weight of handover times of each target LTE cell.

The existing circuit domain fallback frequency point information of the LTE cell includes the GSM cell to which the source LTE cell falls back, the number of fallbacks, and the weight of the fallback times of each fallback GSM cell within a specified period (for example, one week).

The network management system is used for the maintenance of the base station, and can provide all 2G and 4G data required by the embodiment of the present invention, so that it does not depend on the data of the MR server or the terminal side, and can reduce the implementation complexity.

S12. Calculate the weight of each handover frequency point corresponding to the GSM cell according to the historical handover data of the GSM cell, and calculate the weight of each handover frequency point corresponding to the LTE cell according to the historical handover data of the LTE cell;

Each handover frequency point corresponding to the GSM cell is the target GSM cell to which the co-sited GSM cell is handed over in the historical handover process, and the weights of the handover times of each target GSM cell obtained from S11 reflect the handover frequency points to which each handover frequency point is handed over. The handover amount of the target cell. The embodiment of the present invention also calculates the quality weights of each handover frequency point corresponding to the co-sited GSM cell, uses both the handover weight and the quality weight as the index of the frequency point weight, and finally calculates the comprehensive weight corresponding to the handover frequency points of all co-sited GSM cells value.

Each switching frequency point corresponding to the LTE cell is the target LTE cell that the LTE cell is switched to during the historical handover process, and selecting the co-sited GSM cell corresponding to each target LTE cell as the added frequency point can make the frequency point add more complete, the specific method In order to sort the handover weight values of the handover frequency points corresponding to the LTE cells from large to small, the frequency points that can be added to the frequency point configuration table are selected by calculating the cumulative proportion of the handover weight values.

S13. Add the frequency point of the GSM cell co-located with the current LTE cell as a frequency point of class A to the frequency point configuration table;

The embodiment of the present invention provides a frequency point configuration table for adding the GSM fallback frequency point of the LTE cell. The frequency point of the GSM cell co-sited with the current LTE cell should be configured as the fallback frequency point, and the priority should be the highest. In the specific implementation process, the frequency point of the GSM cell that is co-located with the current LTE cell is added to the frequency point configuration table as a class A frequency point, with the highest priority, and the subsequent calculated priority is lower than the fallback frequency point of the class A frequency point All are added after it, with the order of addition as the priority order.

S14. Add a class B frequency point in the frequency point configuration table according to the weight of each switching frequency point corresponding to the GSM cell, and add a class B frequency point in the frequency point configuration table according to the weight of each switching frequency point corresponding to the LTE cell Adding a class C frequency point, and adding a class D frequency point in the frequency point configuration table according to the existing circuit domain fallback frequency point information of the LTE cell;

According to the comprehensive weight value of each handover frequency point corresponding to the co-sited GSM cell calculated in S13, the embodiment of the present invention selects a Class B frequency point and adds it behind the Class A frequency point in the frequency point configuration table, and according to the calculated LTE cell corresponding According to the accumulative proportion of the weight value of each handover frequency point, select the C-type frequency point and add it after the B-type frequency point in the frequency point configuration table, and select the D-type frequency point according to the existing circuit domain fallback frequency point information of the LTE cell It is added after the C-class frequency point in the frequency point configuration table. Taking the order of frequency points added in the frequency point configuration table as the priority order can ensure the integrity of the added frequency points and the added high-quality frequency points correspond to a higher priority.

S15. Configure the frequency point information in the frequency point configuration table in the base station according to the order of priority from front to back.

The circuit domain fallback frequency point configuration method provided by the embodiment of the present invention obtains the information of the GSM cell co-located with the current LTE cell, the historical handover data of the LTE cell and the historical handover data of the co-sited GSM cell, and classifies and processes the acquired data to obtain the priority Class A frequencies, Class B frequencies, Class C frequencies, and Class D frequencies are successively lowered, and the fallback frequencies of LTE cells are configured in order of priority. The embodiment of the present invention uses the calculated comprehensive weight value of the fallback frequency point to sort the priority of the fallback frequency point in the order of the weight value, which can ensure the integrity of the final frequency point addition and the higher priority of the high-quality frequency point , and the implementation complexity is low.

In the embodiment of the present invention, S12 specifically includes the following steps:

The calculation of the weight of each switching frequency point corresponding to the GSM cell according to the historical switching data of the GSM cell includes:

Calculate the product of the handover weight and the quality weight of each handover frequency point corresponding to the GSM cell, and the quality weight is the proportion of the uplink quality in the specified interval multiplied by the proportion of the downlink weight in the specified interval.

Since the weights of the handover times of each target GSM cell obtained from S11 are only reflected in the handover amount of the target cell to which each handover frequency point is handed over, if the handover amount of the frequency points is only issued in order of the size of the frequency point handover amount, it may be due to Some frequency points with better quality are ranked lower, which makes it impossible to switch to high-quality GSM cells. Therefore, the present invention calculates the comprehensive weight of quality and switching amount, which can ensure that high-quality frequency points correspond to higher weight values.

The calculation of the weight of each switching frequency point corresponding to the LTE cell according to the historical switching data of the LTE cell includes:

The handover weights of each handover frequency point corresponding to the LTE cell are accumulated in descending order to account for handover weights.

The embodiment of the present invention also considers that the co-sited GSM cell corresponding to the handover frequency point corresponding to the LTE cell is added as the fallback frequency point in the frequency point configuration table, so as to prevent missing configuration of the fallback frequency point.

In the embodiment of the present invention, S14 specifically includes the following steps:

Adding the class B frequency points in the frequency point configuration table according to the weight of each switching frequency point corresponding to the GSM cell includes:

Adding the handover frequency point corresponding to the GSM cell whose weight value is greater than the specified threshold value as a Class B frequency point to the back of the Class A frequency point in the frequency point configuration table according to the priority order of the weight from large to small;

Adding the class C frequency points in the frequency point configuration table according to the weights of each switching frequency point corresponding to the LTE cell includes:

When the cumulative proportion reaches the specified threshold, the co-site GSM cell frequency points corresponding to the handover frequency points participating in the calculation are added to the frequency points in the priority order of weight from large to small as C-type frequency points. Behind the Class B frequency points in the configuration table;

Adding the class D frequency point in the frequency point configuration table according to the existing circuit domain fallback frequency point information of the LTE cell includes:

According to the existing circuit domain fallback frequency point information of the LTE cell, add fallback frequency points whose fallback request times are greater than the specified threshold as D-type frequency points and add them to the frequency point configuration table in order of priority from large to small. Behind the Class C frequency point.

The frequency point configuration table provided by the embodiment of the present invention adds GSM fallback frequency points sequentially according to the order of priority, and configures the LTE network according to the frequency point configuration table, which can ensure that the terminal preferentially falls back to the optimal GSM frequency point.

In the embodiment of the present invention, after performing S14 in adding a class B frequency point in the frequency point configuration table, the method further includes:

If the frequency point information of a different sector under the GSM cell site that is co-located with the current LTE cell is not in the class B frequency point, add the frequency point of a different sector under the GSM cell site as a supplementary frequency point to the behind the Class B frequency points in the above frequency point configuration table.

In the embodiment of the present invention, after adding the Class A frequency point and the Class B frequency point, check whether the frequency points of different sectors under the GSM cell site co-located with the current LTE cell are in the Class B frequency point, if there is already a Class B frequency point points, the order in the Class B frequency points shall prevail, if not in the Class B frequency points, add the frequency points of different sectors under the GSM cell site to the Class B frequency points in the frequency point configuration table behind, and in front of the C frequency point. This is to ensure the integrity of the addition and prevent the omission of frequency point information that belongs to the same base station as the co-sited GSM but is located in a different direction.

The method for configuring circuit domain fallback frequency points provided by the present invention will be described in detail below with specific examples.

The circuit domain fallback frequency point configuration method provided by the embodiment of the present invention is divided into three steps: basic data acquisition and preprocessing, different data classification processing, and CSFB fallback frequency point configuration output. The specific description is as follows:

Step 1. Acquisition and preprocessing of basic data

The embodiment of the present invention first acquires basic configuration data including: GSM cell point-to-point handover data (B class data), LTE cell point-to-point handover data (C class data), LTE cell existing CSFB fallback frequency point information (D class data), GSM cell \LTE co-site information (Type A data). Then preprocess as follows:

1. Get a week of GSM cell point-to-point handover data from the GSM database, sort the handover pairs according to the number of handovers (ie A>B>C), and calculate the cumulative distribution value (Z%>Y%>X%) at the same time, after preprocessing The data form Table 1:

Table 1

2. Obtain one-week LTE cell point-to-point handover data from the LTE database. Same as the preprocessing of GSM point-to-point handover data, the handover pairs are excluded according to the number of handovers, and the cumulative distribution value (Z%>Y%>X%) is calculated at the same time. The preprocessed data forms Table 2:

Table 2

3. Obtain the existing CSFB fallback frequency point information of the LTE cell for a week from the CSFB platform database (due to the need to deploy the CSFB analysis platform, this data can be selected), the same as the GSM point-to-point handover data preprocessing, exclude according to the number of fallbacks, and at the same time Calculate the cumulative distribution value, and the preprocessed data form Table 3:

table 3

4. Type A data includes the basic data of LTE cells and co-sited GSM cells (including station names, different sectors under the same base station, latitude and longitude, and azimuth). Specifically, the corresponding relationship between GSM/LTE co-sites is sorted out based on the following principles:

1) The station name is the same

2) The site distance is less than 50 meters

3) The azimuth angle of the cell differs by 30 degrees from the absolute value of the cell

Fig. 2 shows a schematic diagram of the corresponding relationship between an LTE cell and a co-sited GSM cell.

As shown in Figure 2, the GSM/LTE co-site correspondence is as follows: LTE cell-1 corresponds to GSM cell-1; LTE cell-2 corresponds to GSM cell-2; LTE cell-3 corresponds to GSM cell-3. Among them, LTE cell-1, LTE cell-2 and LTE cell-3 are sectors belonging to the same base station in different directions. Similarly, GSM cell-1, GSM cell-2 and GSM cell-3 are sectors belonging to the same base station in different directions. sector.

Step 2. Different data classification processing

If the sorting and distribution of the frequency point switching amount in the preprocessed data is completely carried out, some frequency points with better quality may be sorted later, so the embodiment of the present invention comprehensively considers the quality priority and the cumulative weight of the overall switching amount proportion, to ensure the integrity of the final frequency point addition and the priority of high-quality frequency points.

The classification and processing of different data will be described in detail below.

Type A data processing

The priority of the data shall prevail, otherwise it will be supplemented after the processing results of Type B data.

Type B data processing

Based on the point-to-point handover information of the co-sited GSM cell and the uplink and downlink quality information of adjacent cells calculated by the network management system, the comprehensive calculation of the handover amount and quality is performed. According to the calculation results, select the frequency point with a cumulative weight ratio of 95% as the frequency point for the final configuration, and sort according to the weight of the frequency points, and add them according to priority.

Table 4 shows the type B data of the embodiment of the present invention.

As shown in Table 4, the specific algorithm and process of frequency point weight accumulation proportion are as follows:

1. H _k : Indicates the number of requests for handover from the primary GSM cell to the neighboring cell, where the total number of handover requests (H ₁ ~ H _n represent the number of handover attempts to each neighboring cell);

2. U _k : Indicates the proportion (unit %) of the uplink quality of each neighboring cell in the range of 0-4, where k=[1-n];

3. D _k : Indicates the proportion (unit %) of the downlink quality of each neighboring cell in the range of 0-4, where k=[1-n];

4.h _k : Indicates the switching weight of each neighboring cell, where

5.q _k : Indicates the quality weight of each neighboring cell, where q _k =U _k *D _k ;

6.f _k : Indicates the frequency point weight of each neighboring cell, where f _k =h _k *q _k ;

7. R _k : Indicates the cumulative proportion of the weight value of each frequency point, where (F _k is the descending value of f _k , F ₁ >F ₂ >F ₃ >F _n );

8. In the final statistics, if R _k > 95, then the frequency points corresponding to F ₁ ~ F _k are the frequency points that need to be added in the end, and the priority configuration of frequency points is performed according to the weight of the frequency points.

After the processing of the B-type data is completed, the B-type frequency points are added.

As shown in Table 5, the gray part is the added co-site frequency point and Class B frequency point. Select the frequency point with a cumulative proportion of 95% as the Class B frequency point, and add it after the Class A frequency point in the frequency point configuration table. .

C class data processing

By counting the point-to-point handover data of LTE cells, the cumulative ratio calculation of the handover amount of LTE neighboring cells is performed, and the GSM co-sited cells corresponding to the LTE neighboring cells with a cumulative ratio of 95% are compared. The frequency points of these GSM cells are used as The supplementary frequency points of CSFB are added, and they are ranked after the frequency points of Class B. The specific processing flow is the same as the processing steps of type B data, and will not be repeated in this embodiment of the present invention.

Table 6

As shown in Table 6, the gray part is the Class C frequency points that need to be added, sorted by the switching amount from large to small, calculate the cumulative proportion, and select the co-sited GSM corresponding to the LTE cell with a cumulative proportion of 95% as the Class C frequency. point, which is added after the Class B frequency point in the frequency point configuration table.

Type D Data Processing

The network management system counts the actual fallback frequency point information of the LTE cell, screens out the top six frequency points with the number of fallback requests, and adds them as CSFB supplementary frequency points, which are ranked after the C-type data processing.

Table 7 shows a schematic diagram of adding a class D frequency point according to an embodiment of the present invention.

Table 7

As shown in Table 7, the gray part is the Class D frequency point that needs to be added. Select the top six frequency points with the number of fallback requests as the Class D frequency point, and add it after the Class C frequency point in the frequency point configuration table.

Step 3, CSFB fallback frequency point configuration output

According to the GSM frequency point information calculated in step 2, the LTE network is configured according to the sequence priority of the frequency points in the frequency point configuration table.

The embodiment of the present invention considers the quality priority and the cumulative weight ratio of the overall switching volume to ensure the integrity of the final frequency point addition and the priority of high-quality frequency points, which makes up for the missing configuration of CSFB GSM fallback frequency points in the existing scheme. Realize complex defects, and only need to obtain network management data, and do not rely on terminal data to realize fast and accurate configuration of CSFB fallback frequency points, the implementation method is simpler, and adding frequency points is more complete.
