As shown in Figure 1, it is a network architecture diagram applied in the embodiment of the present invention, including an operation and maintenance center OMC and a base station NodeB, each NodeB includes multiple cell cells, and the NodeB periodically monitors the status information of each cell, such as: monitoring cell status Capacity, coverage, etc. At the same time, the monitored cell status information is sent to the OMC device, and the OMC device obtains the hardware device information of each cell according to the status information of each cell, and according to the cell status and hardware device information of each cell, etc., Adjustments are made for each cell by the base station. At present, the cell capacity adjustment strategy of the wireless network is roughly divided into three aspects: load evaluation: extracting the capacity indicators of the live network cell (uplink PRB utilization rate during busy hours, downlink PRB utilization rate during busy hours, maximum number of synchronous users in the cell, cell Total uplink traffic, total downlink traffic of the cell), and evaluate whether the cell belongs to the super-busy cell or the super-idle cell according to the indicators, among which the super-busy cell is expanded, and the super-idle cell is reduced; Over-busy or idle cells, check the hardware resource information under the site, co-site the cell information, and finally formulate a plan for increasing or reducing the capacity of the cell; after implementing the plan for increasing or reducing capacity, network optimization personnel will implement corresponding measures for the over-busy or idle cells.

The embodiment of the present invention proceeds from the demand for capacity increase and decrease of indoor sub-districts, and improves the final capacity adjustment scheme of the sub-district, on the OMC equipment, or other sub-district capacity adjustment devices added between ENODEB and OMC, to accurately analyze the sub-district load situation, Determine whether the community needs to increase or decrease capacity, and at the same time, based on the hardware resource information of the community, decide the final capacity increase or decrease plan, improve work efficiency, improve the accuracy of plan formulation, and save network resources.

As shown in FIG. 2 , it shows a flow chart of a cell capacity adjustment method provided by an embodiment of the present invention, and the method is applied to an OMC device or other cell capacity adjustment devices independent of the OMC device. The method includes the following steps:

Step 100: Obtain the capacity data of the cell;

A mobile user resides in an indoor network and establishes an RRC data link with the network. The NodeB periodically collects cell capacity data and reports the collected data to the OMC or other cell capacity adjustment devices. The capacity data includes: For each cell in the network, the uplink PRB utilization rate P _UP when the cell is busy, the downlink PRB utilization rate P _DOWN when the cell is busy, the maximum number of synchronous users in the cell N _ue , the total uplink traffic T _UP , the total downlink traffic T _DOWN , etc.

Step 200: Calculate the cell capacity elasticity index of the cell to be adjusted according to the capacity data of the cell;

After receiving the above cell capacity data, calculate the cell capacity elasticity index α of the cell to be adjusted, specifically including:

First calculate the maximum number of synchronous state users in the average cell of the whole network cell

According to the research and simulation verification of the inventor for many years, preferably, 0<α≤2, 2<α≤10 and α> 10 As a reference standard for judging the capacity status of the cell, formulate the corresponding cell capacity adjustment plan according to different situations, as shown in Figure 3, including:

Step 320: judging the size of the cell capacity elasticity index;

We divide the cell capacity elasticity index into three cases: 0<α≤2, 2<α≤10 and α>10, when 0<α≤2, go to step 340; when 2<α≤10, go to step 360 ; When α>10, go to step 380.

Step 340: Determine a plan for expanding the capacity of the cell to be adjusted;

When 0<α≤2, it indicates that the capacity elasticity of the cell is insufficient, and capacity expansion is required.

Step 360: Determine not to adjust the capacity of the cell to be adjusted;

When 2<α≤10, it indicates that the elasticity of the community can meet the daily compliance of the community, and there is no need to expand or reduce capacity.

Of course, the above adjustment can be adjusted every day, or can be adjusted periodically according to a preset setting.

As can be seen from the above, the above-mentioned embodiment provided by the present invention automatically obtains the capacity data of each cell in the entire network, calculates the cell elasticity index, and adjusts the capacity in a targeted manner according to the cell elasticity index, thereby improving work efficiency and improving This improves the accuracy of the solution and saves network resources.

Through the hardware calibration system and combined with the capacity elasticity index of the cell, a specific capacity adjustment plan for the cell to be adjusted is determined.

Step 341: Determine the number s of baseband boards at the site and the number p of co-sited cells of the cell to be adjusted;

When p=6s, and s<6, go to step 342;

When p=6s, and s=6, go to step 348;

Step 343: judging whether k-20t is less than 20 (MHz);

When k'≥20, go to step 344;

When k'<20, go to step 345.

Step 344: After adding a baseband board, add a carrier cell;

When k'≥20, it is determined that the capacity expansion solution is to add a carrier cell after adding a baseband board, and the carrier cell may also be a CA secondary cell.

Step 345: judging whether the RRU quantity z of the cell to be adjusted is greater than 1;

According to the size of the RRU number z of the cell to be adjusted obtained in the above steps, when z=1, go to step 346; when z≥2, go to step 347.

Step 346: add main device hardware;

When z=1, it is determined that the capacity expansion solution is adding new main device hardware.

Step 347: performing cell division after adding a baseband board;

When z≥2, it is determined that the capacity expansion solution is to split the cell after adding a baseband board.

Step 348: Add main device hardware;

When p=6s and s=6, it is determined that the capacity expansion solution is to add new main device hardware.

Step 349: Calculate the RRU remaining carrier margin k';

When p<6s, it is judged whether the RRU of the cell has redundant carrier margin k' for capacity expansion, where k'=k-20t, and the value of k' is judged.

Step 350: judging whether k' is less than 20 (MHz);

When k'<20, turn to step 352;

When k'≥20, go to step 351.

Step 351: add a new carrier cell;

When k'≥20, it is determined that the capacity expansion scheme of the cell to be adjusted is a newly added carrier cell. Of course, the newly added carrier cell may also be a newly added CA secondary cell.

Step 352: Whether the RRU number z of the cell to be adjusted is greater than 1;

According to the size of the RRU number z of the cell to be adjusted obtained in the above steps, when z=1, go to step 354; when z≥2, go to step 353.

According to the specific conditions of the cell, the above embodiment adjusts the capacity in a targeted manner by judging the cell capacity elasticity index and the hardware configuration information of the cell to be adjusted, which improves work efficiency, improves the accuracy of the solution, and saves network resources.

Another embodiment of the present invention provides a solution for reducing the capacity of the cell, as shown in Figure 5. In the above embodiment, in step 380, when α>10, the capacity of the cell to be adjusted is adjusted for capacity reduction, specifically , including:

Step 380: Determine a plan for reducing and adjusting the capacity of the cell to be adjusted;

When α>10, the OMC device or the cell capacity adjustment device will collect the hardware configuration information of the cell, including: the number of baseband boards at the site s, the maximum carrier capacity k (MHz) of the RRU, the number of RRU carriers t, the number of RRUs z, and the total The station cell number p and its coverage location information, etc., where the coverage location information is used to indicate whether the cell is continuously covered with other cells. Through the hardware calibration system and combined with the capacity elasticity index of the cell, a specific capacity adjustment plan for the cell to be adjusted is determined.

全网小区平均上行总流量

和全网小区平均下行总流量

以及RRU下各载波小区的小区忙时上行PRB利用率P_UP、小区忙时下行PRB利用率P_DOWN，计算小区弹性指数α，具体计算方案再步骤200中都有描述，在这里不再赘述。From step 200, the OMC equipment or other cell capacity adjustment equipment obtains the capacity data of each cell in the entire network, and then according to the maximum number of synchronous users in the average cell of the entire network

Average uplink total traffic of cells in the whole network

and the average downlink total traffic of the entire network cell

And the uplink PRB utilization rate P _UP and the downlink PRB utilization rate P _DOWN of each carrier cell under the RRU to calculate the cell elasticity index α. The specific calculation scheme is described in step 200 and will not be repeated here.

It should be pointed out that the cell resilience index of each carrier cell under each RRU can be calculated at one time when the system starts capacity adjustment, or can be calculated in real time during the adjustment process. Both calculation methods do not affect the capacity adjustment process. .

Step 382: Judging the cell elasticity index of each carrier cell under each RRU, whether there is a carrier cell with a cell elasticity index greater than 10;

If there is at least one carrier cell with a cell elasticity index greater than 10, go to step 383;

If the cell resilience indices of all the carrier cells under the RRU are less than or equal to 10, or if there is no carrier cell under the RRU, go to step 384 .

Step 383: Determine that the capacity adjustment scheme is the de-network carrier cell;

If there is at least one carrier cell whose cell elasticity index is greater than 10, it means that the capacity of the cell is very flexible, and the carrier cell is directly withdrawn from the network. Of course, if the cell is a CA secondary cell, the CA secondary cell can also be directly withdrawn from the network. .

Step 384: Obtain the cell resilience index of each co-sited cell of the cell to be adjusted;

According to the capacity data information of the cell obtained in the above steps, determine the co-site cell information of the cell to be adjusted, and obtain or calculate the cell elasticity index of each co-site cell according to the method in step 200, the specific calculation method has been carried out in step 200 A detailed description is given and will not be repeated here.

Step 385: Determine whether there is a co-sited cell with a cell elasticity index greater than 10;

After obtaining the cell elasticity indices of all co-sited cells of the cell to be adjusted, determine whether there is at least one co-sited cell with a cell elasticity index greater than 10, if there is no co-sited cell with a cell elasticity index greater than 10 or the cell to be adjusted is not If there is a co-sited cell, go to step 386; if yes, go to step 387, and determine the co-sited cell with the largest cell elasticity index and continuous coverage with the cell to be adjusted from the co-sited cells, see step 387 for details.

Step 386: no adjustment;

If there is no co-sited cell in the cell to be adjusted, or the cell elasticity index of all co-sited cells is not greater than 10, it is determined that the cell capacity adjustment scheme is empty, that is, no adjustment is made.

Step 387: Among the co-sited cells satisfying the cell elasticity index α>10, select the co-sited cell with the largest cell elasticity index;

From the p co-sited cells of the cell to be adjusted, select all α>10 co-sited cells to form an integrated Ω={α _i >10|i=1L m}, where m is from the p co-sited cells, The selected m co-site cells with α>10.

Assuming that the cell j with the largest cell elasticity index is selected from the set Ω={α _i >10|i=1L m}, α _j =Max(α _i |i=1L m).

Step 388: Determine whether cell j has continuous coverage with the cell to be adjusted;

From the above-mentioned cell capacity data, extract the coverage position information to judge whether the coverage of the cell to be adjusted and the jth co-sited cell overlap, if overlap, go to step 389; if not overlap, go to step 390.

Step 389: Merge the cell to be adjusted with the co-sited cell j with the largest cell elasticity index;

If there is overlap, in order to save capacity, the cell to be adjusted and the co-sited cell j are combined as an adjustment scheme.

Step 390: judge whether m is 0;

When the coverage of the jth co-sited cell does not overlap with the coverage of the cell to be adjusted, that is discontinuous coverage, then judge whether there are other co-sited cells in the set Ω, that is, judge whether m is 0, if not If it is 0, go to step 392; if it is 0, go to step 391.

Step 391: no adjustment;

When m is 0, it means that there is no co-sited cell with continuous coverage with the base station to be adjusted in the set Ω, and the capacity adjustment scheme is determined as: no adjustment.

Step 392: delete the cell j, m=m-1;

If there are other co-sited cells in Ω, delete the above-mentioned cell j from the set, m=m-1, continue to judge whether the co-sited cell with the largest capacity elasticity index of other cells has continuous coverage with the cell to be adjusted, and go to step 387 , continue to judge. Until a co-sited cell with continuous coverage with the cell to be adjusted is found, or no co-sited cell with continuous coverage with the cell to be adjusted is found.

In the above-mentioned embodiment, by judging the capacity elasticity index of the cell and the hardware configuration information of the cell to be adjusted, targeted capacity reduction adjustments are carried out according to the specific conditions of the cell, which improves work efficiency, improves the accuracy of the plan, and saves network resources. resource.

In actual practice, the OMC or other cell capacity adjustment devices will make prudent judgments and determine an accurate adjustment plan before executing the cell capacity adjustment. According to the cell capacity adjustment plan in the above-mentioned embodiments, OMC or other cell capacity adjustments determine the daily sky-level cell capacity adjustment plan, which can be adjusted according to the sky-level cell capacity adjustment plan, or statistically adjusted according to the sky-level cell capacity adjustment plan Probability of the plan, the final adjustment plan is determined by week or month or other time periods, as shown in Figure 6:

Step 410: Count all adjustment plans within a predetermined time period;

It is possible to count the day-level cell capacity adjustment plans reported by the OMC or other cell capacity adjustment devices within a week, and count the duration of each plan in units of weeks.

Step 411: Judging whether there is an adjustment plan whose duration is greater than the first threshold;

Set the first threshold to 3 days, if in the most recent week, there are more than 3 consecutive days in the community, the planned capacity increase and decrease plans are consistent, then further judge whether the adjustment plan is no adjustment, and go to step 412.

If the duration of none of the adjustment schemes exceeds the first threshold within a week, go to step 415 and end the capacity adjustment judgment for this week.

Step 412: Determine whether the adjustment plan is no adjustment;

If the plan is no adjustment, it means that the capacity allocation of the cell is normal, and no operation is required, and the process goes to step 415 to end the judgment of capacity adjustment for this week.

If the scheme is not no adjustment, go to step 413.

Step 413: take the scheme as the final adjustment scheme for adjusting the capacity of the adjusted cell;

This scheme is used as the final adjustment scheme for adjusting the capacity of the adjusted cell, and is fed back to the OMC equipment.

Step 414: Adjust the capacity of the cell to be adjusted according to the final capacity adjustment scheme.
