The application scenarios of the present invention are described below.

The present invention provides a method for establishing a business distribution relationship between communication network cells, based on ABIS signaling (the interface between the BSC base station controller and the BTS base station signaling station in the GSM global mobile communication system) MR measurement report, for each For the existing network cell, accurately calculate the cell level coverage and quality relationship, and divide the signal quality level threshold; then calculate the service ratio that the cell can share according to the MR accurate information; then combine the signal quality level with the MR measurement information Threshold, calculate the service distribution coefficient between cells; finally get the service distribution matrix of the entire network. The invention utilizes the real MR data reported by the user of the ABIS port to obtain the service distribution of the cells in the network and the relationship among them, so as to provide the basis for the accurate planning and optimization of the service. The MR data source of the present invention may come from the ABIS port, or from OMC (Operation and Maintenance Center) data statistics related to the ABIS port, and some drive test statistical data may also obtain part of the MR report.

As shown in Figure 4, the method specifically includes:

Step 1: Import the basic data of the community.

The basic data of the cell includes: the basic engineering parameters and network parameters of the cell in the network. Taking the GSM network as an example, it mainly includes the following information:

Cell CGI global cell identification code: used to distinguish different cells in the network

Community longitude and latitude: distinguish the geographic location of the community

Cell height, antenna azimuth, downtilt: as a reference for cell information

BCCH broadcast control channel of the cell: BCCH channel frequency

BSIC base station identification code of the cell: composed of NCC network color code and BCC base station color code, used to identify the base station

neighbor list.

Step 2: Analysis of ABIS port MR data.

For the GSM system, the MR measurement report (Measurement Result) is the main means for the network side to obtain terminal wireless information. It mainly includes two parts: uplink signal information and downlink signal information. Among them, the downlink signal information is measured and collected by the network terminal, and reported to the network through the Measurement Report signaling of the Um port; the uplink signal information is measured and collected by the BTS (Base Transceiver Station) on the network side. The BTS summarizes the uplink and downlink measurement information and reports it to the BSC base station controller through the MR, and the BSC processes and monitors the user's wireless situation, and maintains better call services through switching when necessary.

The MR measurement report of the present invention includes: the level strength and signal quality of the serving cell, the signal strength and BSIC of the six strongest (the present invention takes 6 as an example) measurement cells, and the basic data format is as follows in Table 3:

The information of each serving cell is combined with the BCCH and BSIC information of the measuring cell, and the CGI information of the measuring cell can be found from the neighboring cell table of the serving cell and the neighboring cell table of the neighboring cell table. Therefore, from Table 1, the following Table 4 can be obtained:

Step 3: Create a cell-level level and quality relationship table.

In a certain period of time, the level and quality of a certain cell in the network are counted, because each cell has different quality statistics at a certain level, so the data is summarized in Table 5 (for a certain cell):

Generally speaking, users have a better perception of the quality of grades 0-5, so the above table is summarized for the quality of grades 0-5 at each level, and the following table 6 is obtained:

Step 4: Cell-level signal quality level threshold establishment

According to Table 3, the signal quality level threshold T is calculated. The meaning of the signal quality level threshold T is: when the level of the serving cell is higher than this threshold, the signal quality provided can be as high as possible. The quality here is represented by the 0-5 quality ratio. In general, the signal quality is mainly determined by the C/I signal-to-noise ratio. In the case of a certain interference, increasing the signal level of the serving cell can ensure the highest possible signal-to-noise ratio, thereby ensuring the highest possible signal quality, so it is necessary to calculate the signal quality level threshold.

The calculation method is as follows:

First, set the signal quality threshold T _quality ;

Then, for -110<=Z<=-47, calculate: (indicates the proportion of samples from level 0-5 when the level is higher than Z);

If Q _U ≥ T _quality , end. Z at this time is used as the signal quality level threshold of the cell.

Figure 5 is a schematic diagram of the relationship between the level strength and the proportion of signal quality samples of grades 0-5. It can be seen from Figure 5 that as the level increases, the 0 The proportion of -5 levels is getting higher and higher, and the level value at T _quality is the level threshold we need. That is to say, when this threshold is reached, access to the cell can be guaranteed to obtain better service quality. In Figure 5, if the high quality threshold is set to 98.5%, then the obtained level threshold is -63db.

Step 5: Calculation of the shareable traffic ratio of the main control cell.

The shareable traffic ratio R of the main control cell indicates the proportion of all services of the main control cell that can be shared by other cells, and can guarantee better quality. The calculation idea is: compare the measured cell level in the MR information with the signal quality level threshold, and if it is greater than the signal quality level threshold, it means that it can be shared.

The calculation process is as follows:

MR _k,i represents the i-th MR of the k-th cell Cell _k , k=1,...,K, i=1,...,I;

Here k is the serial number of the cell in the network; K represents the number of cells in the network, K is a natural number greater than 0,

i is the serial number of the MR of the subdistrict; I represents the quantity of the MR of the kth subdistrict; I is a natural number greater than 0;

T _k,i,j represents the high-quality level threshold when the k-th first cell is used as the serving cell and the j-th second cell of the i-th MR is used as the measurement cell

NR _k,i indicates whether the i-th MR of the k-th cell can be shared, 1 means yes, 0 means no;

NY(Cell _k ,Cell _k,i,j ) indicates the number of business shares of the kth serving cell, the ith MR, and the jth measurement cell;

Rx _k,i,j represent the level value of the kth serving cell, the ith MR, and the jth measurement cell;

In this embodiment, 6 measurement cells are set,

for k=1,...,K;

j=1,...,6;

If Rx _k,i,j ≥ T _k,i,j , then NR _k,i =1; at the same time, the counter NY(Cell _k ,Cell _k,i,j ) corresponding to T _k,i,j is added by 1;

Then, Calculate the shareable traffic ratio R _k of the kth serving cell.

Step 6: Calculation of inter-cell service sharing coefficients.

On the basis of step 5, the next step is to accurately calculate the correlation coefficient of traffic that the kth cell can share with other cells. Since there may be more than one cell satisfying the condition in step 5 during the measurement process, and there may be no cell satisfying the condition, at this time it is necessary to perform fine calculations between cell pairs.

The service sharing coefficient X(m,n) indicates the proportion of services that can be shared with n cells while ensuring high quality when m is the main serving cell.

Step 7: Establishment of business distribution matrix relationship.

The service distribution matrix represents the coefficient relationship matrix of service sharing between cells in the network under the premise of ensuring quality.

Specifically: traverse all cells in the network; calculate each cell and its related service sharing coefficient X(m,n).

The present invention has the following beneficial effects:

1. Use the ABIS port MR measurement report data actually reported by the user for processing, reflecting user perception and network performance.

2. The level and quality aggressive association division thresholds are adopted, reflecting the reliability of service sharing.

3. Quantify the mutual service balance relationship between the services of the community, and provide an accurate basis for the optimization of the service performance of the community. The research on the interrelationship of business distribution among the cells reflects the internal correlation between the services of the cells, and provides precise guidance for business planning and balance optimization.

The above description is a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
