Description

Technical Field

[0001] This invention relates to the field of communication network optimization implementation, and specifically provides a method and apparatus for a cell timed shutdown strategy. Background Technology

[0002] With the rapid development of mobile services, the number of users in the network is constantly increasing, and higher demands are being placed on accessibility, latency, and speed. Along with the development of network construction, the scale of base station network equipment is also gradually expanding. The huge network scale and the large number of base station equipment have caused a huge waste of resources, which has a serious impact on the environment and economy. In order to improve the environmental and economic benefits of wireless networks, energy conservation and emission reduction have become important goals of current communication networks.

[0003] How to address the increasingly serious problems of energy consumption and environmental pollution in existing technologies is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention addresses the shortcomings of the prior art by providing a practical method for a timed shutdown strategy for cells.

[0005] A further technical objective of this invention is to provide a reasonably designed, safe, and applicable cell timed shutdown strategy device.

[0006] The technical solution adopted by this invention to solve its technical problem is: A cell timed shutdown strategy method is proposed. By collecting and analyzing PM and PRB performance and MRO data of cells, the quality of co-covered cells is assessed. The cell shutdown adjustment order is determined by sorting the overlapping coverage ratio within the co-coverage group from low to high. Then, the hourly traffic volume of the cell and the capacity carrying capacity of the co-coverage group cells are combined to determine whether the cell needs to be shut down.

[0007] Furthermore, collect 15-minute granularity cell PM and PRB performance data from each main equipment manufacturer's cell to determine the cell's service capacity. Collect 15-minute granular MRO data from each main equipment manufacturer's cell, calculate the cell overlap coverage rate, and configure base station engineering parameters.

[0008] Further, the specific steps are as follows: S1. Obtain PM / PRB performance data of relevant cells from the equipment manufacturer's OMC network management system, obtain daily network optimization parameters data from the asset management data platform, and obtain data of cells with shared coverage from the network optimization platform; S2. Collect and analyze MRO data from the equipment manufacturer's OMC network management system to calculate the most recent overlap coverage rate of the co-covered cells; S3. Based on cell resources, PRB performance and overlapping coverage rate, perform quality assessment on co-covered cells and calculate quality scores; S4. Determine the order of cell adjustment, remove the cells to be retained, and sort the cells to be adjusted according to their quality scores within the co-coverage group. The highest score has a priority of 1, and so on. S5. Statistically analyze hourly downlink traffic and average number of RRC connected users using cell performance data. S6. Capacity determination of shared coverage groups: Generate hourly granular data of the previous day every day, summarize according to the downlink utilization rate report of the cell hourly granularity, and obtain the index data of shared coverage. S7. Determine the cell operation strategy by generating downlink traffic to determine the cell operation strategy and based on the average number of connected users in RRC, using co-coverage cell quality assessment data, cell adjustment order judgment data, and co-coverage group capacity judgment data. S8. Cell enable / disable judgment: enable or disable the cell, obtain the cell operation strategy based on downlink traffic and the cell operation strategy based on the average number of connected users in RRC, compare the strategies, use the strategy that enables more cells, and output the cell enable / disable judgment table.

[0009] Furthermore, in step S3, when calculating the quality score, the following is done: (1) Bandwidth score: 20M bandwidth scores 20, 10 / 15M bandwidth scores 40; (2) Interference score: 100 if the score is higher than the threshold of -105dBm, otherwise 0; (3) Overlapping coverage score: The overlapping coverage score is sorted from low to high according to the overlapping coverage ratio within the co-coverage group, with a score of 1-15 points; The total quality score is calculated by summing the scores from the three items mentioned above.

[0010] Furthermore, in step S4, the reserved areas are calculated as urban and county town reserved areas and township and rural reserved areas; The calculation of the reserved residential areas in urban and county towns is as follows: (1) Retain the bottom layer cells of the coverage group. The frequency of the coverage layer is FDD900 / F1 / F2. When FDD900 exists, FDD900 cells must be retained. When FDD900 cells do not exist, the cell with the lower quality assessment score of F1 / F2 cells is selected to ensure that at least one cell is retained in the coverage layer. (2) Retain the bottom cell of the capacity layer of the co-coverage group. The capacity layer frequency is D. The cell with the lowest quality assessment score is selected from cell D to ensure that at least one cell is retained in the capacity layer. (3) Reserve anchor cells, anchor cells for FDD1800 and other frequency cells, and the other frequency cells are determined by the parameter "whether it is an NSAENB cell".

[0011] Furthermore, in step S4, the calculation of township and rural reserved areas is as follows: The bottom layer cells of the shared coverage group are retained, and the coverage layer frequency is FDD900 / F1 / F2. When FDD900 exists, the FDD900 cell must be retained. Among the F1 and F2 cells, the cell with the lower quality assessment score is selected. When no FDD900 cell exists, the cell with the lower quality assessment score is selected from F1 / F2 cells to ensure that at least one coverage layer is retained.

[0012] Furthermore, in step S6, the indicator data includes the following: (1) Actual downlink traffic of shared coverage: Obtain hourly data of the cells in the shared coverage group for the previous few weeks, take the maximum downlink traffic of the hourly data of each cell for the previous few weeks, and add them together according to the shared coverage group. Among them, cells whose "whether the retained cells are included in the capacity calculation" in the cell adjustment order judgment table are excluded. (2) Average number of RRC connected users in the co-coverage group: Obtain hourly data of the co-coverage group cells in the previous weeks. For each cell, take the average number of RRC connected users during the period of the maximum downlink traffic in the previous weeks. Add them together according to the co-coverage group. Among them, cells whose "whether the reserved cell is included in the capacity calculation" in the cell adjustment order judgment table are excluded.

[0013] (3) Downlink traffic of the bottom layer of the common coverage group: The downlink traffic of the cell is obtained by adding up the downlink traffic according to the ideal bearer configuration table of frequency band; (4) Average number of RRC connected users at the bottom layer of the common coverage group: The average number of RRC connected users in the cell is obtained by adding them together according to the ideal bearer configuration table of frequency bands; (5) Downlink traffic: Demand downlink traffic for the shared coverage group - Actual downlink traffic for the shared coverage group; (6) Average number of RRC connected users: Total coverage group required average number of RRC connected users - Total coverage actual average number of RRC connected users.

[0014] Furthermore, in step S7, the operation strategy is a downlink traffic-based cell operation strategy and a cell operation strategy based on the average number of connected users in RRC. The downlink traffic determination cell operation strategy is as follows: (1) If the downlink traffic is >0, it is determined that non-bottom cell needs to be enabled. Based on the "downlink traffic of the bottom layer of the common coverage group", the enabling judgment is made from the highest to 1 according to the priority shutdown order of the common coverage group. If one is enabled, the downlink traffic corresponding to the cell is obtained. The calculation stops when the downlink traffic of the activated cell plus the downlink traffic of the underlying layer of the shared coverage group is just greater than the actual downlink traffic of the shared coverage; the activated cell is marked as activated and the cells that do not need to be activated are marked as deactivated; or when the downlink traffic of the entire coverage group is still less than the actual downlink traffic of the shared coverage. The operation judgment of the activated cell and the bottom cell is recorded as "activated", and the rest of the cells are recorded as "deactivated". (2) If the downlink flow is less than or equal to 0, it is determined that non-bottom cells need to be shut down. The operation judgment of the bottom cell is recorded as "on", and the other cells are recorded as "off".

[0015] Furthermore, when determining cell operation strategies based on the average number of connected users per RRC connection; (1) If the average number of connected users in RRC is >0, it is determined whether the non-bottom cell needs to be turned off or on. Based on the "average number of connected users in RRC at the bottom of the common coverage group", the opening judgment is made from the highest to 1 according to the priority shutdown order of the common coverage group. If one is turned on, the average number of connected users in RRC corresponding to the cell is obtained. The calculation stops when the sum of the average number of connected RRC users in the active cells and the average number of connected RRC users at the bottom layer of the coverage group is just greater than the actual average number of connected RRC users in the coverage group. Active cells are marked as active, and cells that do not need to be active are marked as inactive. Alternatively, if the number of active cells in the entire coverage group is still less than the actual average number of connected RRC users in the coverage group, the calculation stops. The operation judgment of the activated cell and the bottom cell is recorded as "activated", and the rest of the cells are recorded as "deactivated". (2) If the average number of connected users in RRC is less than or equal to 0, it is determined that non-bottom cells need to be shut down. The operation judgment of bottom cells is recorded as "on", and the other cells are recorded as "off".

Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The following is a preferred embodiment: In this embodiment, the PM and PRB performance and MRO data of the cells are collected and analyzed to conduct a quality assessment of the co-covered cells. The cells are sorted from low to high according to the overlap coverage ratio within the co-coverage group to determine the order of cell shutdown adjustment. Then, the hourly traffic volume of the cells and the capacity carrying capacity of the co-coverage group cells are combined to determine whether the cells need to be shut down.

[0022] Collect 15-minute granularity cell PM and PRB performance data for each main equipment manufacturer's cell to determine the cell's service capacity; Collect 15-minute granular MRO data from each main equipment manufacturer's cell, calculate the cell overlap coverage rate, and configure base station engineering parameters.

[0023] The specific steps are as follows: S1. Obtain PM and PRB performance data of relevant cells from the equipment manufacturer's OMC network management system, obtain daily network optimization parameters data from the asset management data platform, and obtain data of cells with shared coverage from the network optimization platform; S2.

Among them, the preserved communities are calculated separately for urban and county town preserved communities and township and rural preserved communities; The calculation of preserved residential areas in urban areas and county towns is underway, as follows: (1) Retain the bottom layer cells of the coverage group. The frequency of the coverage layer is FDD900 / F1 / F2. When FDD900 exists, FDD900 cells must be retained. When FDD900 cells do not exist, the cell with the lower quality assessment score of F1 / F2 cells is selected to ensure that at least one cell is retained in the coverage layer. (2) Retain the bottom cell of the capacity layer of the co-coverage group. The capacity layer frequency is D. The cell with the lowest quality assessment score is selected from cell D to ensure that at least one cell is retained in the capacity layer. (3) Reserve anchor cells, anchor cells for FDD1800 and other frequency cells, and the other frequency cells are determined by the parameter "whether it is an NSAENB cell".

[0025] The calculation of township and rural preservation areas is as follows: Retain the bottom layer cells of the shared coverage group: The coverage layer frequency is FDD900 / F1 / F2. When FDD900 exists, the FDD900 cell must be retained. Among the F1 and F2 cells, the cell with the lower quality assessment score is selected.

[0026] When no FDD900 cell exists, the cell with the lower quality assessment score is selected from F1 / F2 cells to ensure that at least one coverage layer is retained.

[0027] S5. Statistically analyze hourly downlink traffic and average number of RRC connected users using cell performance data. S6. Capacity determination of shared coverage groups: Generate hourly granular data of the previous day every day, summarize according to the downlink utilization rate report of the cell hourly granularity, and obtain the index data of shared coverage. The indicator data includes the following: (1) Actual downlink traffic of shared coverage: Obtain hourly data of the cells in the shared coverage group for the previous few weeks, take the maximum downlink traffic of the hourly data of each cell for the previous few weeks, and add them together according to the shared coverage group.

[0028] (3) Downlink traffic of the bottom layer of the common coverage group: The downlink traffic of the cell is obtained by adding up the downlink traffic according to the ideal bearer configuration table of frequency band; (4) Average number of RRC connected users at the bottom layer of the common coverage group: The average number of RRC connected users in the cell is obtained by adding them together according to the ideal bearer configuration table of frequency bands; (5) Downlink traffic (actual - underlying layer): Downlink traffic demanded by the common coverage group - Actual downlink traffic of the common coverage group; (6) Average number of RRC connected users (actual - underlying layer): Average number of RRC connected users required for the total coverage group - Average number of actual RRC connected users for the total coverage. The ideal bearer configuration table for each frequency band is as follows: E 20 120 13.5 3DMIMO 20 126 12 FDD1800 20 64 6 D 20 60 6.1 D 10 30 3.05 A 15 33 3.9 F1 20 36 3.7 F1 15 18 1.85 F1 10 18 1.85 F2 10 14 1.1 F2 15 7 5.5 F2 10 7 5.5 S7. Determine the cell operation strategy by generating downlink traffic to determine the cell operation strategy and based on the average number of connected users in RRC, using co-coverage cell quality assessment data, cell adjustment order judgment data, and co-coverage group capacity judgment data. The operational strategies are: downlink traffic-based cell operation strategy and RRC-based average number of connected users-based cell operation strategy. The downlink traffic determination cell operation strategy is as follows: (1) If the downlink traffic (actual - bottom layer) > 0, it is determined whether the non-bottom layer cell needs to be turned off or turned on. Based on the "downlink traffic of the bottom layer of the common coverage group", the turn-on judgment is made from the highest to the lowest according to the priority turn-off order of the common coverage group. If one cell is turned on, the downlink traffic corresponding to the cell is obtained (frequency band ideal bearer configuration table).

[0029] The calculation stops when the downlink traffic of the activated cell plus the downlink traffic of the underlying layer of the shared coverage group is just greater than the actual downlink traffic of the shared coverage, and the activated cell is marked as activated, and the cells that do not need to be activated are marked as deactivated, or when the downlink traffic of the entire coverage group is still less than the actual downlink traffic of the shared coverage.

[0033] like Figure 2 As shown in Example 2: Downlink traffic (actual - underlying layer) > 0, total covered actual downlink traffic: 20, total coverage group configuration: FDD900+FDD1800+D1+F1. If the total downlink traffic is still less than the total covered actual downlink traffic even when all coverage groups are enabled, then FDD900+FDD1800+D1+F1 needs to be enabled.

[0034] like Figure 3 As shown in Example 3: Downlink traffic (actual - underlying layer) < 0, total actual downlink traffic covered: 7, total coverage group configuration: FDD900+FDD1800+D1+F1+F2+D3+D4. Then, if the underlying cell is enabled and the other cells are disabled, then FDD900+FDD1800+D1 needs to be enabled, and F1+F2+D3+D4 needs to be disabled.
