By obtaining the network load index data of the cells in the area to be analyzed, the congestion situation of each cell, the code resource load, and the load of the surrounding close neighbors are monitored. And when the obtained network load index shows that there is a cell that reaches the corresponding processing threshold, that is, when a cell is congested, determine the target neighbor cell that needs to adjust the parameter configuration information, and adjust the parameter configuration of the congested cell and the target neighbor cell Information, realize the resource balance effect of the cell in the area to be analyzed, and avoid the complexity of manual operation. When determining the congested cell in the area to be analyzed, it can be determined according to the network load index, such as according to the code resource utilization Rate to determine whether a cell is a congested cell, when the code resource utilization rate of the cell exceeds the preset threshold value, the cell is considered to be a congested cell.

In the above inter-cell resource balancing method, wherein, according to the MR data of the congested cell, determining the cell that needs to adjust the parameter configuration information from the neighboring cells of the congested cell as the target neighboring cell is specifically: according to the The level difference between the congested cell and the adjacent cells of the congested cell in the MR data of the measurement report of the congested cell is determined as the target adjacent cell from the adjacent cells of the congested cell that needs parameter configuration information adjustment.

After a cell is determined to be a congested cell, the surrounding cells of the cell are prioritized according to the level difference between the cell and the surrounding cells of the cell included in the MR (MeasurementReport, measurement report) data, wherein The greater the difference between the level of the neighboring cell and the level of the cell, the higher the priority of the surrounding neighboring cell, and the surrounding neighboring cell with the highest priority is the target neighboring cell that needs parameter configuration information adjustment, and can be obtained from the MR The cell parameter configuration information is obtained from the data, wherein the cell parameter configuration information includes: cell power configuration, cell handover parameter configuration, cell reselection parameter configuration, number of neighbor cells of the cell, neighbor cell relationship, cell power configuration, Primary serving cell and/or neighbor cell handover level at which the cell initiates handover.

In the above resource equalization method between cells, the adjusting the parameter configuration information of the congested cell and the target neighboring cell further includes: adjusting the power of the congested cell and the target neighboring cell.

The inter-cell resource balancing method provided by the present invention automatically forms two scheme strategies, one master and one backup, by comprehensively analyzing the obtained cell parameter configuration information and network load index data:

Strategy 1: Adjust the strategy through handover parameters and/or reselection parameters between cells to achieve resource balance between cells. As shown in Figure 3, for congested cells, adjust handover and reselection parameters to make congested cells Re-select, difficult to cut in/difficult to re-select" and the target neighbor cell "difficult to cut out/difficult to re-select, easy to cut in/easy to re-select";

Strategy 2: By implementing corresponding power adjustment strategies for severely congested cells, the coverage of the cells is optimized to achieve resource balance among cells.

For the case of cell congestion caused by too many users at the edge of the cell, strategy 1 can usually be adopted when realizing resource balance between cells, by adjusting the handover and reselection parameters of the cell, the users at the edge of the cell are handed over to the resources of the cell. Neighboring cells, thereby reducing the number of users in the cell and alleviating cell congestion; and when the cell congestion is not significantly relieved after adopting strategy 1, strategy 2 can be adopted to reduce the coverage of the cell by adjusting the power of the cell, thereby Reduce the number of users in the cell so that the resources provided by the cell can satisfy the users within the coverage of the cell and alleviate cell congestion.

In the above inter-cell resource balancing method, wherein the adjusting the handover parameters and/or reselection parameters between the congested cell and the target neighbor cell is specifically: adjusting the congested cell and the target neighbor cell Adjusting handover parameters between cells, promoting handover of users in the congested cell to the target adjacent cell, and inhibiting handover of users in the target adjacent cell to the congested cell; and/or adjusting the handover between the congested cell and the The reselection parameters between the target adjacent cells are adjusted to promote reselection of users in the congested cell to the target adjacent cell, and suppress reselection of users in the target adjacent cell to the congested cell.

By adjusting the handover parameters, the congested cell is difficult to switch in and easy to switch out, and the target adjacent cell is easy to switch in and difficult to switch out, so as to realize the resource balance among the cells; where, the handover parameter refers to: the user in the cell goes to the adjacent cell of the cell During handover, parameters related to the difficulty of handover; for example, the parameter CIO (CellIndividualOffset, cell individual offset), when the value of the cell is set to a positive value, it is easier for users in the cell to handover to the neighboring cell, that is, it can speed up The handover of the user from the cell to the neighboring cell; on the contrary, when it is a negative value, the handover of the user from the cell to the neighboring cell is delayed.

By adjusting the reselection parameters, the congested cell is difficult to reselect and easy to reselect, and the target neighbor cell is easy to reselect and difficult to reselect, so as to achieve resource balance between cells; where the reselection parameters refer to: When the user reselects to the neighboring cell of the cell, the parameters related to the difficulty of reselection; for example, the parameter Qoffset (cell reselection offset), when the value of the cell is set to a negative value, the user in the cell is easier Reselection to the neighboring cell, that is, it can speed up the reselection of the user from the cell to the neighboring cell; on the contrary, when it is a positive value, it delays the reselection of the user from the cell to the neighboring cell.

In the above inter-cell resource balancing method, wherein the adjusting the power of the congested cell and the target neighboring cell is specifically: adjusting the power of the congested cell and the target neighboring cell, reducing the power of the congested cell and the target neighboring cell. Coverage of the congested cell, expanding the coverage of the target adjacent cell, so that users in the congested cell switch or reselect to the target adjacent cell.

By adjusting the power level, the coverage of the congested cell is reduced and the coverage of the target adjacent cell is increased, so that the number of users within the coverage of the congested cell is reduced, and some users enter the coverage of the target adjacent cell, realizing inter-cell communication. Resource balance.

The resource balancing method between cells provided by the present invention is obtained by obtaining reference factors such as cell congestion times, congestion rate, number of users in the cell, number of BRU occupancy, code resource utilization, and handover times with neighboring cells, and according to the needs of the cell. Index thresholds for load balancing (such as congestion times thresholds, utilization thresholds), so as to determine whether resource balancing is required. When resource balancing is required, combined with the level difference between the cell and its surrounding neighbors reported by the MR during handover, the surrounding neighbors of the cell are prioritized to determine the target neighbor cell, and the above adjustment strategy is used to adjust the relevant parameters. Adjust to achieve resource balance, as shown in Table 1 below:

Table 1

Among them, in the adjustment strategy of the handover parameters and/or reselection of the cell, the handover parameters and/or the reselection adjustment size are determined, and then the MML script is automatically generated and sent to the RNC in real time for execution, so as to share the edge users of the cell to the target Neighborhood.

Taking the parameters CIO and Qoffset as an example, the adjustments to the parameters CIO and Qoffset are determined through the relationship shown in Table 2:

Table 2

Among them, AdBm refers to the level of the source cell at the time of handover, BdBm refers to the level of the source cell at the time of handover, (B-A)dB refers to the level difference at the time of handover obtained according to MR statistics, INT is a rounding function; ROUNDUP refers to a value away from zero, The number is rounded up; the cio from the source cell to the target cell is the rounded value of the difference between the level of the target cell at the time of handover and the level of the source cell at the time of handover multiplied by 2. When congestion occurs in the source cell, handover or reselect to the target cell, and determine the handover and reselection parameters according to the above table.

For example: there is an existing cell 1, and its neighbor cell is cell 2. According to the obtained switching levels of cell 1 and cell 2, it can be known that when the level of cell 1 is -96.02dbm, the level of cell 2 is -86.5dbm At this time, cell 1 initiates handover to cell 2; if cell 1 is congested, in order to reduce the number of users in cell 1, more users in cell 1 can be switched to cell 2, and by adjusting the switching parameters, cell 2 The handover level is reduced, so that more users can be handed over to cell 2. As shown in Table 3, the handover parameter CIO from cell 1 to cell 2 is set to 18. Correspondingly, the handover parameter CIO from cell 2 to cell 1 Set it to -18, use the inter-cell handover offset (CELLINDIVIDALOFFSET), in the handover algorithm, realize the effect of changing the cell handover boundary.

table 3

Execute the script as follows:

MODTNCELL:CELLID="Cell 1", PLMNMCC="460", PLMNMNC="00", NRNCID="XXX", NCELLID="Cell 2", CELLINDIVDALOFFSET=18;

MODTNCELL:CELLID="Cell 2", PLMNMCC="460", PLMNMNC="00", NRNCID="XXX", NCELLID="Cell 1", CELLINDIVDALOFFSET=-18;

Since the decision threshold for cell handover is: (target cell level value + target cell to serving cell handover CIO/2) > (serving cell level value + preset hysteresis value), target cell to serving cell handover CIO/2 = serving cell The rounded value of the difference between the level minus the level of the target cell; when the hysteresis of cell 1 remains unchanged, at this time, as long as it meets: (level value of cell 2+18/2)≥-86dbm, that is: the target The handover can occur when the level value of cell 2 is -95dbm, that is, the level requirement for cell 2 is lowered when the handover occurs, so that more users in cell 1 can switch to cell 2, and the users in cell 1 The number of users decreases, which alleviates the congestion of cell 1;

In the strategy for adjusting the reselection parameters of the cell, the reselection parameters of the cell may be adjusted so that the cell is easy to be reselected but difficult to be reselected.

For example: According to the obtained reselection levels of cell 1 and cell 2, it can be known that when the level of cell 1 is -96.02dbm and the level of cell 2 is -86.5dbm, cell 1 can initiate reselection to cell 2 ; If congestion occurs in cell 1, in order to enable more users in cell 1 to be reselected to cell 2, the reselection level of cell 2 is reduced by adjusting the reselection parameters so that more users can reselect To cell 2, as shown in Table 4, the reselection parameter Qoffset from cell 1 to cell 2 is set to -10, correspondingly, the handover parameter Qoffset from cell 2 to cell 1 is set to 10, with the help of the central cell and adjacent cells The adjustment of the offset (QOFFSET1SN), in the process of cell selection and reselection, changes the boundary of the cell reselection band.

Table 4

Execute the script as follows:

MODTNCELL:CELLID="Cell 1", PLMNMCC="460", PLMNMNC="00", NRNCID="XXX", NCELLID="Cell 2", QOFFSET1SN=-10;

MODTNCELL:CELLID="Cell 2", PLMNMCC="460", PLMNMNC="00", NRNCID="XXX", NCELLID="Cell 1", QOFFSET1SN=10;

Since the decision threshold for cell reselection is: (level value of the target cell - reselection Qoffset from the target cell to the serving cell) > (level value of the serving cell + preset hysteresis value), when the hysteresis of cell 1 remains unchanged, if the cell The reselection parameter Qoffset of 1 is set to -10. At this time, as long as it satisfies: (level value of cell 2-(-10))≥-86dbm, that is, it can occur when the level value of target cell 2 is -96dbm Reselection, that is: when reselection occurs, the level requirements for cell 2 are lowered, so that more users in cell 1 can be reselected to cell 2;

In the power adjustment strategy for the cell, the resources between the cells are balanced by adjusting the power of the cell and its surrounding neighbors, as shown in Figure 4: there is a cell A and its surrounding neighbors cell B and cell C , where cell A is severely congested, and resource balancing between cells is required.

By reducing the power of cell A by xdbm, the coverage of cell A changes from the range defined by the solid line in the figure to the range defined by the dotted line, that is, the coverage of cell A becomes smaller, reducing the number of users within the coverage of cell A However, if only the power of cell A is adjusted without adjusting the power of its neighbors, it is likely that the coverage of cell A will become smaller and cause weak coverage. In order to avoid weak coverage The power of the neighboring cells of cell A can be adjusted, the power of cell B can be increased by x1dbm, and the power of cell C can be increased by x2dbm, so that the coverage of cell B and cell C can be enlarged to avoid weak coverage. By reducing the power of high-load cells and increasing the power of neighboring cells, the coverage radius of the cell is changed, so that users are reasonably shared.

Execute the script as follows:

MODTPCPCCH:CELLID=cell A, PCCPCHPOWER=Y-x;

MODTPCPCCH:CELLID=cell B, PCCPCHPOWER=Y+x1;

MODTPCPCCH:CELLID=Cell C, PCCPCHPOWER=Y+x2;

Wherein, Y represents the PCCPCH power configured in the live network of the corresponding cell.
