Detailed ways

In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the method for finding the ping-pong handover cell pair provided by the embodiment of the present application includes:

Step 101. Obtain the number of handover requests and the number of handover terminals for each cell according to the terminal signaling data of the open interface;

Step 102, according to the number of handover requests and the number of handover terminals in each cell, determine the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network;

Step 103, according to the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network, determine all ping-pong handover characteristic cells;

Step 104, for each ping-pong handover characteristic cell, determine the ping-pong handover characteristic according to the number of handovers and the number of handover terminals from the ping-pong handover characteristic cell to each adjacent cell and according to the average number of handovers per terminal in the ping-pong handover characteristic cell All ping-pong switching cell pairs of the cell.

In step 101, for the 2G network, the terminal signaling of the open interface can be A port signaling, for the 3G network, the terminal signaling of the open interface can be the Iu port signaling, and for the 4G network, the terminal signaling of the open interface can be It is S1 port or X2 port signaling.

For a cell, the number of handover requests refers to the sum of the number of times the cell is requested to switch to an adjacent cell, and the number of handover terminals refers to the number of terminals in the cell. For example, cell A has 3 adjacent cells. There are 3 terminals in total. The number of times the first terminal in cell A requests to switch to the first adjacent cell is 3, and the number of times the second terminal in cell A requests to switch to the second adjacent cell is 5. The number of handover requests of A is 8, and the number of handover terminals in cell A is 3.

In step 102, the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network are determined according to the number of handover requests and the number of handover terminals in each cell.

In step 103, all characteristic cells for ping-pong handover are determined according to the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network. After the ping-pong handover characteristic cell is determined, only the ping-pong handover characteristic cell is further screened to find out adjacent cells that can form a ping-pong characteristic cell pair with the ping-pong handover characteristic cell.

In step 104, the number of handovers from the ping-pong handover characteristic cell to an adjacent cell refers to the number of times the ping-pong handover characteristic cell requests handover to the adjacent cell, and the number of handover terminals refers to the number of terminals requesting handover to the adjacent cell.

The method provided in the embodiment of this application obtains the number of handover requests and the number of handover terminals in each cell according to the terminal signaling data of the open interface, and then determines the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network times, then determine all the ping-pong handover characteristic cells, for each ping-pong handover characteristic cell, select all adjacent cells that can form the ping-pong handover cell pair from its adjacent cells, form the ping-pong handover cell pair with the ping-pong handover characteristic cell, The method has the following beneficial effects: since the required data comes from open interfaces and does not require any interaction with the manufacturer's equipment, the method is not limited by the manufacturer's equipment and does not depend on the manufacturer's switching performance statistics; secondly, the method According to the characteristics of the ping-pong handover cell, the ping-pong handover cell is searched, which avoids the analysis bottleneck caused by the huge amount of analysis data, and at the same time can comprehensively search for the ping-pong handover cell pair that appears on the network; finally, because the analysis data comes from an open interface, it is suitable for 2G, 3G, The search for ping-pong handover cell pairs of multiple networks in different regions of 4G is not limited by the network standard or handover type.

Specifically, in the above step 102, according to the number of handover requests and the number of handover terminals in each cell, there are many ways to determine the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network. The sum of the number of switching requests in a period of time is taken as the number of switching requests of a cell, and the number of terminals requesting switching in the multiple time periods is taken as the number of switching terminals. For the time period for determining the number of switching requests and the number of switching terminals The selection method is not limited in the present invention.

Optionally, the determining the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network according to the number of handover requests and the number of handover terminals in each cell includes:

For a cell, the ratio of the number of switching requests of the cell within the set time length to the number of handover terminals of the cell within the set time length is taken as the average number of handover times per terminal in the cell;

The ratio of the sum of the number of handover requests of all cells in the entire network within the set time period to the sum of the number of handover terminals in all cells of the entire network within the set time length is taken as the average number of handover times per terminal in the entire network.

In the above method, the ratio of the number of handover requests of a cell in a set time length to the number of handover terminals in the cell within the set time length is taken as the average number of handover times per terminal in the cell, and the handover times of all cells in the entire network within the set time length The ratio of the sum of the number of requests to the sum of the number of handover terminals in all cells in the entire network within the set time period is used as the average number of handover times for each terminal in the entire network. Since the set time length is a continuous time period, it can be concentrated to reflect that the cell is in this time period. In this way, it can be more accurately judged whether the cell and the adjacent cell can form a ping-pong handover cell pair.

Among the above methods, there are many methods for selecting the duration, and the value can be selected according to actual needs, for example, the value can be 5 minutes, 1 hour or 1 day, etc. If the convenience of data processing is considered, it can be The value is 5 minutes. If data integrity is considered, the value is 1 day.

After determining the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network, it is necessary to screen out all the characteristic cells of ping-pong handover from all the cells, where the definition of the characteristic cell of ping-pong handover is defined in advance is to indicate that a certain cell can be identified as one of the cells in the ping-pong handover cell pair. There are many ways to define the characteristic cell of ping-pong handover. For example, the characteristic cell of ping-pong handover is defined as a cell whose average number of handovers per terminal is greater than the average number of handovers per terminal in the entire network. The cell whose handover times difference of each terminal is greater than a certain threshold, the specific definition method depends on the actual needs.

Optionally, according to the average number of handovers per terminal in each cell and the average number of handovers per terminal in the entire network, determining all ping-pong handover characteristic cells includes:

For a cell, if the ratio of the average number of handovers per terminal in the cell to the average number of handovers per terminal in the entire network within the set time exceeds a first threshold, then it is determined that the cell is a ping-pong handover characteristic cell.

In this method, if the ratio of the average number of handovers per terminal in a cell to the average number of handovers per terminal in the entire network exceeds the first threshold, the cell is defined as a ping-pong handover characteristic cell, for example, cell B is in The average number of handovers per terminal within the set duration is 10, the average number of handovers per terminal in the entire network is 4, and the first threshold value is 2. Since 10/4>2, it can be determined that cell B is a ping-pong handover characteristic cell ; Another example is that the average number of handovers per terminal in cell C is 6, the average number of handovers per terminal in the entire network is 4, and the first threshold value is 2. Since 6/4<2, it can be determined that cell C is not a ping-pong handover characteristic cell . The above-mentioned determination of the ping-pong handover characteristic cell, because the ratio of the average number of handovers per terminal within the set time length to the average number of handovers per terminal in the entire network exceeds the first threshold is determined as the characteristic cell of ping-pong handover, indicating that the average number of handovers per terminal of the cell exceeds the first threshold. The number of handovers of a terminal is relatively large, so the possibility of ping-pong handover cells is very high, so this method can better find out the ping-pong handover cell pairs in the entire network.

In addition, there are many methods for determining the value of the first threshold in the above method. For example, the first threshold can be a specific value according to the actual situation, such as 1.5, 2, etc. The following provides the first threshold provided by the embodiment of the present application. A threshold value method.

Optionally, the first threshold is determined according to the following manner:

For a cell, if the average number of handovers per terminal in the cell is greater than the average number of handovers per terminal in the entire network, then determine the average number of handovers per terminal in the cell as the first candidate value;

Select one from all first candidate values, and determine the first threshold according to the first candidate value and the average number of handovers per terminal in the entire network.

In the above method, if the average number of handovers per terminal in a cell is greater than the average number of handovers per terminal in the entire network, then determine the average number of handovers per terminal in the cell as the first candidate value, and then select one of the first candidate values , determining the first threshold according to the first candidate value and the average number of handovers per terminal in the entire network. For example, there are 1,000 cells in the entire network, and the average number of handovers per terminal in the entire network is 100. Among the 1,000 cells, the average number of handovers per terminal in 400 cells is greater than 100. The average number of handovers per terminal in these 400 cells is The number of handovers is used as the first candidate value, and then one of the first candidate values is selected according to actual needs. For example, the average number of handovers per terminal in cell D in the candidate value is 150, and then the average number of handovers per terminal in the entire network is 100. A first threshold is determined. There are many ways to determine the first threshold by using the first candidate value and the average switching times of each terminal in the whole network, and one way used in the embodiment of the present application is given below.

Optionally, the average switching times of each terminal in the whole network is Y ₀ , and a value Y _N is selected from the first candidate value, then the first threshold value is determined to be 1+α, where α=(Y _N -Y ₀ )/ Y ₀ , so if the ratio of a cell Y _i to the average number of handovers per terminal in the entire network is Y ₀ is greater than the first threshold, then the cell Y _i is determined to be a ping-pong handover characteristic cell, that is, if Y _i >Y ₀ *(1 +α), then the cell Y _i is determined as the ping-pong handover characteristic cell. As for the specific value of the first threshold, an example is given below, for example, Y ₀ =100, Y _N =150, then α=0.5, and the first threshold is 1.5.

The above method provides a specific method for determining the characteristic cell of ping-pong handover, that is, if the number of handovers per terminal in a cell Y _i and the average number of handovers per terminal in the entire network are Y ₀ satisfying Y _i >Y ₀ *(1+ α), then the cell Y _i is determined as a ping-pong handover characteristic cell, where 1+α is the first threshold, and α=(Y _N -Y ₀ )/Y ₀ , and a value Y selected from the first candidate value _N can be selected according to actual needs, and has good practical application ability and flexibility. This method can well determine the ping-pong handover characteristic cells in the whole network, and truly reflect the ping-pong handover characteristics.

After determining all the ping-pong handover characteristic cells from the whole network, next, it is necessary to determine the ping-pong handover cell pair according to each ping-pong handover characteristic cell and the adjacent cells of the ping-pong handover characteristic cell, for example, there are 1000 cells in the whole network, A total of 200 ping-pong handover characteristic cells are screened out, and then the ping-pong handover cell pair is further searched for each ping-pong handover characteristic cell. For example, cell E belongs to one of 200 ping-pong handover characteristic cells, and cell E has 20 adjacent cells. For cell E, it is necessary to find a cell that satisfies certain conditions with cell E from 20 adjacent cells, and determine it as a pair of ping-pong switching cells. For example, 5 cells and cell E in 20 adjacent cells meet the search conditions. Then the cell E and the five adjacent cells respectively form a ping-pong handover cell pair, that is, the cell E has five ping-pong handover cell pairs. For how to determine the ping-pong handover cell pair of a ping-pong handover characteristic cell, there are many definition methods. Neighboring cells are determined as ping-pong handover cell pairs, and so on.

In step 104, a method for determining the pair of ping-pong handover cells is provided, that is, according to the number of handovers and the number of handover terminals from the ping-pong handover characteristic cell to each adjacent cell and the average number of handover terminals per terminal according to the ping-pong handover characteristic cell times, determine all the ping-pong handover cell pairs of the ping-pong handover characteristic cell, and the method is described in detail below.

Optionally, all ping-pong handovers of the ping-pong handover characteristic cell are determined according to the number of handovers and the number of handover terminals from the ping-pong handover characteristic cell to each adjacent cell and according to the average number of handovers per terminal in the ping-pong handover characteristic cell Cell pairs, including:

According to the number of handovers and the number of handover terminals from the ping-pong handover characteristic cell to each adjacent cell within the set time length, determine the average number of handovers per terminal from the ping-pong handover characteristic cell to each adjacent cell;

For an adjacent cell of the ping-pong handover characteristic cell, if the ratio of the average number of handovers per terminal from the ping-pong handover characteristic cell to the adjacent cell and the average number of handovers per terminal of the ping-pong handover characteristic cell exceeds a second threshold, Then it is determined that the ping-pong handover characteristic cell and the adjacent cell are a ping-pong handover cell pair.

The above method, for a ping-pong handover characteristic cell, first determine the average number of times each terminal is handed over from the ping-pong handover characteristic cell to each adjacent cell, for example, the ping-pong handover characteristic cell F has 3 adjacent cells F1, F2, F3, determine The average number of handovers per terminal in the ping-pong handover characteristic cell F to the three adjacent cells, for example, the average number of handovers per terminal from cell F to cell F1 is 20, and the average number of handovers per terminal from cell F to cell F2 The number of handovers of each terminal is 26, and the average number of handovers of each terminal from cell F to cell F3 is 21.

Next, for the ping-pong handover characteristic cell and one of the adjacent cells, determine whether the ping-pong handover characteristic cell and the adjacent cell form a ping-pong handover cell pair, the specific method is: if the ping-pong handover characteristic cell sends If the ratio of the average number of handovers per terminal to the average number of handovers per terminal of the ping-pong handover characteristic cell exceeds a second threshold, it is determined that the ping-pong handover characteristic cell and the adjacent cell are a ping-pong handover cell pair. For example, the ping-pong handover characteristic cell i has n adjacent cells N ₁ , N ₂ ,..., N _n , and for one of the adjacent cells N _j , request handover from cell i to cell N _j within the set duration The number of times is A _i N _j , and the number of handover terminals from the ping-pong handover characteristic cell i to the cell N _j within the set duration is B _i N _j , then determine the average number of handovers Y per terminal from the ping-pong handover characteristic cell i to the cell N _{j i} N _j =A _i N _j /B _i N _j , the average number of handovers per terminal in the ping-pong handover feature cell i is Y ₀ , if the ratio of Y _i N _j to Y ₀ is greater than the second threshold, then determine the ping-pong Handover feature cell i and neighboring cell _Nj form a ping-pong handover cell pair. In this method, the ratio of the average number of handovers per terminal from a ping-pong handover characteristic cell to an adjacent cell and the average number of handovers per terminal in a ping-pong handover characteristic cell is greater than the second threshold as checking whether the ping-pong handover characteristic cell and the adjacent cell are ping-pong The basis for switching cell pairs fully considers the switching relationship between the ping-pong handover characteristic cell and adjacent cells, so the ping-pong characteristic cell pairs in the entire network can be well determined.

There are many methods for determining the value of the second threshold. For example, the second threshold can take a specific value according to the actual situation, such as 1.5, 2, etc. The method for determining the value of the second threshold provided by the embodiment of the present application is given below .

Optionally, the second threshold is determined according to the following manner:

For an adjacent cell of the ping-pong handover characteristic cell, if the average number of handovers per terminal from the ping-pong handover characteristic cell to the adjacent cell is greater than the average number of handovers per terminal of the ping-pong handover characteristic cell, then the The average number of handovers per terminal from the ping-pong handover characteristic cell to the adjacent cell is determined as a second candidate value;

Select one from all the second candidate values, and determine the second threshold according to the second candidate value and the average handover times per terminal of the ping-pong handover characteristic cell.

The above method, if the average number of handovers per terminal from a ping-pong handover characteristic cell to an adjacent cell is greater than the average number of handovers per terminal from a ping-pong handover characteristic cell, then the average number of handovers per terminal from a ping-pong handover characteristic cell to an adjacent cell It is determined as the second candidate value, and then one of the second candidate values is selected, and the second threshold is determined according to the candidate value and the average number of handovers per terminal of the ping-pong handover characteristic cell. For example, the ping-pong handover characteristic cell i has 20 adjacent cells, the average number of handovers per terminal in the ping-pong handover characteristic cell i is 100, and 9 cells in the 20 cells satisfy the average handover times from the ping-pong handover characteristic cell to the adjacent cell. The number of terminal handoffs is greater than 100, then the average number of handoffs per terminal from the ping-pong handover characteristic cell to these 9 cells is used as a candidate value, and then a second candidate value is selected therefrom according to actual needs, such as ping-pong handover in the second candidate value The average number of handovers per terminal from the characteristic cell to adjacent cell k is 120, and then the second threshold is determined jointly with the average number of handovers per terminal from the characteristic cell i of ping-pong handover. There are many ways to determine the second threshold by using the second candidate value and the average handover times per terminal of the ping-pong handover characteristic cell, and one way used in this embodiment of the present application is given below.

Optionally, the average number of handovers per terminal in the characteristic cell i of ping-pong handover is Y _i , and a value is selected from the second candidate value as Y _i N _k , that is, the average number of handovers from characteristic cell i to neighboring cell k in ping-pong handover The number of terminal handovers Y _i N _k determines that the second threshold is 1+β, where β=(Y _i N _k -Y _i )/Y _i , so if the ping-pong handover feature cell i to the adjacent cell j averages each terminal The ratio of the number of handovers Y _i N _j and the average number of handovers per terminal of the ping-pong handover characteristic cell i to Y _i is greater than the second threshold, then it is determined that the ping-pong handover characteristic cell i and the adjacent cell j form a ping-pong handover cell pair, that is, if Y _i N _j >Y _i *(1+β), then it is determined that the ping-pong handover characteristic cell i and the adjacent cell j form a ping-pong handover cell pair. As for the specific value of the second threshold, an example is given below, for example, if Y _i =100, Y _i N _k =200, then β=1, and the second threshold is 2.
