[0034] Figure 2 The flowchart of the cell capacity problem optimization method provided by the embodiments of the present application is shown in FIG. 2, which includes the following steps 201, 202, and 203. Figure 2
[0035] Step 201, acquiring network index data of a cell, the network index data including: RRC connection maximum number of users, uplink PRB average utilization, downlink PRB average utilization, and PDCCH channel CCE occupancy rate.
[0036] Specifically, the execution subject of each step in the method can be a cell capacity problem optimization device (or a capacity optimization platform, a capacity management system, etc.). The device can be implemented by software and / or hardware, and the device can be integrated in an electronic device. The electronic device can be a network device, a terminal device (such as a smart phone, a personal computer, etc.), a server (such as a local server or a cloud server, which can also be a server cluster, etc.), a processor, a chip, etc.
[0037] For ease of description, the execution subject of each step in the method will be referred to as a capacity management system in the following embodiment description.
[0038] The capacity management system can automatically acquire network index data of each cell (e.g., periodically from the OMC network management system), including: maximum number of radio resource control (RRC) connections, average utilization of uplink physical resource blocks (PRBs), average utilization of downlink PRBs, and control channel element (CCE) occupancy rate of a physical downlink control channel (PDCCH), which are used as analysis indexes for capacity problems.
[0039] Step 202: If at least one network index data of the cell is greater than or equal to the corresponding index threshold, the cell is determined as a capacity problem cell.
[0040] Specifically, for a certain cell, the capacity management system can determine whether the cell is a capacity problem cell according to the above four network index data of the cell. If at least one network index data of the cell is greater than or equal to the corresponding index threshold, the cell is determined as a capacity problem cell.
[0041] The index threshold corresponding to the maximum number of RRC connections can be the number of users supported by the cell. The index thresholds corresponding to the average utilization of uplink PRBs, the average utilization of downlink PRBs, and the CCE occupancy rate of the PDCCH channel can be flexibly set as needed, for example, the index threshold corresponding to the average utilization of uplink PRBs can be set to 85%, the index threshold corresponding to the average utilization of downlink PRBs can be set to 85%, and the index threshold corresponding to the CCE occupancy rate of the PDCCH channel can be set to 70%.
[0042] In some embodiments, if a certain network index data of a cell is greater than or equal to the corresponding index threshold, the network index data is determined as "high"; if a certain network index data of a cell is less than the corresponding index threshold, the network index data is determined as "normal"; and if the size relationship between a certain network index data and the corresponding index threshold cannot be determined (e.g., data is missing), the network index data is determined as "unknown". It can be understood that if at least one of the above four network index data of a cell is "high", the cell is determined as a capacity problem cell, or a cell with high load status.
[0043] Step 203: Based on the number of users supported by the cell and the same coverage different frequency cell situation of the cell, output a capacity problem optimization scheme of the cell.
[0044] Specifically, for the capacity problem cell, the capacity management system can output the capacity problem optimization scheme of the cell based on the number of users supported by the cell and the same coverage inter-frequency cell situation of the cell, and the specific implementation can have various forms, which are not limited here.
[0045] In some embodiments, the number of users supported by the cell can be determined according to the configuration parameters of the cell, and the same coverage inter-frequency cell situation of the cell can be determined according to the engineering parameter data, which are not specifically limited here.
[0046] The cell capacity problem optimization method provided by the embodiments of the present application can judge whether each cell is a capacity problem cell based on the RRC connection maximum user number, the uplink PRB average utilization, the downlink PRB average utilization and the PDCCH channel CCE occupancy rate of the cell, and for the capacity problem cell, the capacity problem optimization scheme of the cell can be output based on the number of users supported by the cell and the same coverage inter-frequency cell situation of the cell, so as to realize automatic monitoring and automatic optimization adjustment of the capacity problem cell, effectively reduce the influence of human factors on the judgment, and improve the work efficiency of the on-site capacity problem optimization.
[0047] In some embodiments, outputting the capacity problem optimization scheme of the cell based on the number of users supported by the cell and the same coverage inter-frequency cell situation of the cell includes: Outputting the capacity problem optimization scheme of the cell based on the comparison result between the RRC connection maximum user number of the cell and the number of users supported by the cell; and
[0048] In the case that at least one of the uplink PRB average utilization, the downlink PRB average utilization and the PDCCH channel CCE occupancy rate of the cell is greater than or equal to the corresponding index threshold, outputting the capacity problem optimization scheme of the cell based on the same coverage inter-frequency cell situation of the cell.
[0049] Specifically, the optimization scheme for the capacity problem cell can be divided into two aspects to output optimization suggestions. On the one hand, the RRC connection maximum user number of the cell can be checked, and the capacity problem optimization scheme of the cell can be output according to the comparison result between the RRC connection maximum user number of the cell and the number of users supported by the cell. On the other hand, for the problem cell with high utilization, that is, at least one of the uplink PRB average utilization, the downlink PRB average utilization and the PDCCH channel CCE occupancy rate of the cell is greater than or equal to the corresponding index threshold, the capacity problem optimization scheme of the cell can also be output according to the same coverage inter-frequency cell situation of the cell, so that the optimization processing for the capacity problem cell is more comprehensive, and the cell capacity problem can be solved more effectively.
[0050] In some embodiments, outputting the capacity problem optimization scheme of the cell based on the comparison result between the RRC connection maximum user number of the cell and the number of users supported by the cell includes: (1) In the case that the RRC connection maximum user number of the cell is less than the user number supported by the cell, output the optimization scheme for the capacity problem of the cell, including: suggest observation.
[0051] Specifically, for the capacity problem cell, if the RRC connection maximum user number of the cell is less than the user number supported by the cell, it indicates that a small number of users may cause high load, such as a small number of users performing large buffer transmission services. In this case, no further processing can be performed temporarily, and the capacity management system can output an optimization suggestion: suggest observation.
[0052] (2) In the case that the RRC connection maximum user number of the cell is greater than or equal to the user number supported by the cell, output the optimization scheme for the capacity problem of the cell, including: suggest configuring parameters of a larger capacity level.
[0053] Specifically, for the capacity problem cell, if the RRC connection maximum user number of the cell is greater than or equal to the user number supported by the cell, it indicates that the RRC user is over limit. In this case, the capacity management system can output an optimization suggestion: suggest configuring parameters of a larger capacity level, that is, configuring parameters corresponding to a level with a larger user number than the current user number supported by the cell for the cell. For example, the current user number supported by the cell is 200, and it is assumed that the next larger level is 400 users. The cell can be configured with configuration parameters corresponding to 400 users to alleviate the capacity problem of the cell.
[0054] (3) In the case that the RRC connection maximum user number of the cell is greater than or equal to the user number supported by the cell, and there is a same coverage different frequency cell in the cell, output the optimization scheme for the capacity problem of the cell, including: suggest starting the load balancing function.
[0055] Specifically, for the capacity problem cell, if the RRC connection maximum user number of the cell is greater than or equal to the user number supported by the cell, and there is a same coverage different frequency cell in the cell, the capacity problem of the cell can be alleviated through load balancing. The capacity management system can output an optimization suggestion: suggest starting the load balancing function, so as to allow the same coverage different frequency cell to share a part of the user number of the cell, so as to achieve the purpose of alleviating the capacity problem of the cell.
[0056] In some embodiments, based on the same coverage different frequency cell situation of the cell, output the optimization scheme for the capacity problem of the cell, including: (1) In the case that there is a same coverage different frequency cell in the cell, output the optimization scheme for the capacity problem of the cell, including: suggest starting the load balancing function.
[0057] Specifically, for the problem cell with high utilization rate, if the cell exists a same coverage inter-frequency cell, it can be checked first whether the load balancing function of the cell is started, and if not, the capacity problem optimization scheme of the cell can be output, including: suggesting to start the load balancing function, so as to let the same coverage inter-frequency cell share part of the user number of the cell, so as to achieve the purpose of relieving the capacity problem of the cell.
[0058] (2) In the case that the cell exists a same coverage inter-frequency cell and the load balancing function of the cell is started, if the load rate of the same coverage inter-frequency cell of the cell is less than or equal to the set load rate, the capacity problem optimization scheme of the cell can be output, including: suggesting to lower the signal transmission power of the cell by a set step.
[0059] Specifically, for the problem cell with high utilization rate, if the cell exists a same coverage inter-frequency cell, and the load balancing function of the cell has been started, it indicates that the load balancing effect is not ideal, and in this case, if the load rate of the same coverage inter-frequency cell of the cell is less than or equal to the set load rate (such as 50%), the capacity problem optimization scheme of the cell can be output, including: suggesting to lower the signal transmission power of the cell by a set step (such as 3dB), so as to make the terminal preferentially select the same coverage inter-frequency cell of the cell, so that the same coverage inter-frequency cell can share part of the user number of the cell, so as to achieve the purpose of relieving the capacity problem of the cell.
[0060] It should be noted that the set load rate and the set step can be flexibly set according to needs, and the present application does not make specific limitation.
[0061] In some embodiments, the above signal transmission power can include Synchronization Signal Block (SSB) transmission power, PDCCH Demodulation Reference Signal (DMRS) transmission power, Physical Downlink Shared Channel (PDSCH) DMRS transmission power, etc.
[0062] (3) In the case that the cell has no same coverage inter-frequency cell, the capacity problem optimization scheme of the cell can be output, including at least one of the following: suggesting to adjust the signal transmission power of the cell, suggesting to adjust the inter-frequency handover parameter of the cell, suggesting to adjust the interoperation threshold parameter of the cell, suggesting to adjust the voice user priority access parameter of the cell, and suggesting to adjust the admission algorithm parameter of the cell.
[0063] Specifically, for the problem cell with high utilization rate, if the cell does not exist the same coverage inter-frequency cell, the capacity problem optimization scheme of the cell can be outputted to include at least one of the following: suggesting adjusting the signal transmission power of the cell, suggesting adjusting the inter-frequency handover parameter of the cell, suggesting adjusting the interoperation threshold parameter of the cell, suggesting adjusting the voice user priority access parameter of the cell, and suggesting adjusting the admission algorithm parameter of the cell.
[0064] The adjusting the signal transmission power of the cell can include reducing the SSB transmission power, the PDCCH DMRS transmission power, the PDSCH DMRS transmission power, and the like of the cell.
[0065] The adjusting the inter-frequency handover parameter of the cell can include adjusting the A2 reporting reference signal receiving power (RSRP) threshold, the A1 reporting RSRP threshold, the NR cell inter-frequency carrier information (coverage-based handover measurement event type), the A4 reporting RSRP threshold, and the A5 reporting RSRP threshold 1 of the cell. In some embodiments, the adjusting the inter-frequency handover parameter of the cell needs to meet the condition that "there is an inter-frequency cell within 1km of the cell, and the inter-frequency cell is not the same coverage inter-frequency cell of the cell", and if not met, the inter-frequency handover parameter of the cell is not adjusted, because if there is no inter-frequency cell within 1km of the cell, adjusting the inter-frequency handover parameter of the cell is not helpful for solving the capacity problem, at which time other optimization schemes can be used.
[0066] The adjusting the interoperation threshold parameter of the cell can include adjusting the B2 reporting RSRP threshold, the A2 reporting RSRP threshold, and the A1 reporting RSRP threshold of the cell.
[0067] The adjusting the voice user priority access parameter of the cell can include adjusting the voice user priority access switch, the voice user priority access resource reservation threshold, the voice user priority access small bandwidth part (BWP) resource reservation proportion, and the voice user priority access resource reservation trigger preemption proportion of the cell.
[0068] The adjusting the admission algorithm parameter of the cell can include adjusting the admission algorithm switch, the connection user number based admission switch, the connection user number based high percentage threshold, the connection user number based admission recovery percentage threshold, the maximum supported user number, the access control exemption reason bitmap, and the wait time carried by the RRC Reject message triggered by the admission control of the cell.
[0069] Table 1 below is an optimization scheme example when the cell does not have the same coverage inter-frequency cell.
[0070] Table 1 Optimization scheme example when the cell does not have the same coverage inter-frequency cell
[0071] In some embodiments, the number of users supported by the cell can be determined based on at least one of the following parameters of the cell: a Channel State Information (CSI) reporting period; a number of PRBs occupied by a Channel Quality Indicator (CQI).
[0072] For example, a parameter configuration example of a Time Division Duplex (TDD) mode is shown in Table 2, and a parameter configuration example of a Frequency Division Duplex (FDD) mode is shown in Table 3. It can be seen that, whether it is a TDD mode or an FDD mode, the number of users supported by the cell can be determined according to the value of the parameter (the CSI reporting period and / or the number of PRBs occupied by the CQI). For example, in Table 1, the CSI reporting period is 80 slots, and the number of users supported by the cell is 200 UEs (UEs refer to the number of users).
[0073] In this application, NR refers to New Radio (NR), PUCCH refers to Physical Uplink Control Channel (PUCCH), SA refers to Standalone (SA), and NSA refers to Non Standalone (NSA).
[0074] Table 2 Parameter configuration example of TDD mode
[0075] Table 3 Parameter configuration example of FDD mode
[0076] In some embodiments, the same coverage inter-frequency cell of the cell includes an outdoor cell satisfying a first condition and an indoor cell satisfying a second condition. The first condition is that the distance between the outdoor cell and the cell is less than a first distance threshold, and the azimuth angle between the outdoor cell and the cell is less than a first angle threshold. The second condition is that the distance between the indoor cell and the cell is less than a second distance threshold.
[0077] Specifically, the co-coverage inter-frequency cell of the cell can be determined according to the engineering parameter data. The outdoor cell and the indoor cell are identified by the engineering parameter data. For the outdoor cell, if the distance between a certain outdoor inter-frequency neighboring cell and the cell is less than a first distance threshold (for example, 50 meters), and the azimuth angle between the certain outdoor inter-frequency neighboring cell and the cell is less than a first angle threshold (for example, 20 degrees), the certain outdoor inter-frequency neighboring cell can be determined as the co-coverage inter-frequency cell of the cell. For the indoor cell, if the distance between a certain indoor inter-frequency neighboring cell and the cell is less than a second distance threshold (for example, 10 meters), the certain indoor inter-frequency neighboring cell can be determined as the co-coverage inter-frequency cell of the cell.
[0078] It should be noted that the first distance threshold, the first angle threshold, and the second distance threshold can be flexibly set as needed, and the present application does not make specific limitations.
[0079] It should be noted that the azimuth angle less than the first angle threshold can mean that the azimuth angle difference between the two cells is less than the first angle threshold, or that the azimuth angle difference between the two cells is greater than (360 degrees - the first angle threshold).
[0080] In some embodiments, the method further comprises: After outputting the capacity problem optimization scheme of the cell, if the frequency of the PRB utilization rate of the cell exceeding the utilization rate threshold reaches the expansion standard within the monitoring period, an expansion suggestion is output.
[0081] Specifically, for the capacity problem cell, the capacity management system can continuously monitor the cell after outputting the capacity problem optimization scheme of the cell. If the frequency of the PRB utilization rate of the cell exceeding the utilization rate threshold reaches the expansion standard within the monitoring period, an expansion suggestion can be output. For example, the expansion standard can be pre-set as at least 5 days within a week satisfying "at least 5 times of the PRB utilization rate of the cell exceeding 80% per day". If the frequency of the PRB utilization rate of the cell exceeding the utilization rate threshold reaches the expansion standard within the monitoring period, the capacity management system can output an expansion suggestion to better solve the capacity problem of the cell.
[0082] The PRB utilization rate includes at least one of the uplink PRB average utilization rate and the downlink PRB average utilization rate. That is, at least one of the uplink PRB average utilization rate and the downlink PRB average utilization rate of the cell exceeds the utilization rate threshold, indicating that the PRB utilization rate of the cell exceeds the utilization rate threshold. The utilization rate threshold can be flexibly set as needed, and the present application does not make specific limitations.
[0083] In some embodiments, the method further comprises: After outputting the capacity problem optimization scheme of the cell, if the average utilization rate of uplink PRB, the average utilization rate of downlink PRB and the PDCCH channel CCE occupancy rate of the cell in the monitoring period are all less than the set threshold, the cell is closed loop processed.
[0084] Specifically, for the capacity problem cell, the capacity management system can continuously monitor the cell after outputting the capacity problem optimization scheme of the cell, and if the average utilization rate of uplink PRB, the average utilization rate of downlink PRB and the PDCCH channel CCE occupancy rate of the cell in the monitoring period are all less than the set threshold, it can be considered that the capacity problem of the cell is solved, and the cell can be closed loop processed, that is, no longer continuously reported to remind, thereby realizing the automatic closed loop of the capacity problem of the cell.
[0085] The set threshold can be a uniform set value, or different thresholds can be set for the average utilization rate of uplink PRB, the average utilization rate of downlink PRB and the PDCCH channel CCE occupancy rate. The specific threshold value can be flexibly set according to the needs, and the present application does not make specific limitation. For example, the set threshold of the average utilization rate of uplink PRB and the average utilization rate of downlink PRB can be 70%, and the set threshold of the PDCCH channel CCE occupancy rate can be 60%.
[0086] The method provided by the above embodiments of the present application is illustrated by specific examples as follows.
[0087] Figure 3 The cell capacity problem optimization process example provided by the embodiments of the present application is shown in FIG. 1, and the main process includes: Figure 3 1. Automatic data acquisition: The counter report automatic output and the network management automatic output of the parameter configuration data of the cell are realized through the OMC network management system, and the operation and maintenance efficiency is improved.
[0088] 2. Data cleaning and index: The data cleaning of the indexes such as the maximum number of RRC connections, the average utilization rate of uplink PRB, the average utilization rate of downlink PRB and the PDCCH channel CCE occupancy rate in the original counter is performed, and the number of users supported by the cell is counted according to the parameter configuration data of the cell, and the cell is labeled with the number of supported users.
[0089] 3. Threshold automatic judgment: The threshold or dynamic threshold of the indexes such as the maximum number of RRC connections, the average utilization rate of uplink PRB, the average utilization rate of downlink PRB and the PDCCH channel CCE occupancy rate is determined, as shown in Table 4.
[0090] Table 4: Determination example of each index
[0091] The load state of the cell is determined according to the determination result of each index, as shown in Table 5 below, and the cell in a high load state is a capacity problem cell, and the cell can also be marked as which capacity problem (such as a problem cell with high utilization rate).
[0092] Table 5 Determination example of cell load state
[0093] 4. Parameter optimization: according to different performances of the load state of the cell, PRB utilization rate, etc., different optimization suggestions are given for the case that the parameter does not meet the demand of the number of users, there is a same coverage cell or there is no same coverage cell, etc.
[0094] (1) For the cell in a high load state, the maximum number of RRC connections is checked. According to the following checking results, the corresponding optimization suggestions are output: a) RRC connection maximum number ≤ cell supported user number, output optimization suggestion: a small number of users leads to high load, suspected of large buffer transmission service of a user, and observation is suggested.
[0095] b) RRC connection maximum number ≥ cell supported user number, and uplink PRB utilization rate, downlink PRB utilization rate, and CCE occupancy rate are not "high", output optimization suggestion: RRC user overruns, and it is suggested to configure parameters of a larger capacity position. As shown in Table 6 below, parameter configuration can be performed according to the current supported user number of the cell to a larger user number.
[0096] Table 6 Execution example of configuring parameters of a larger capacity position
[0097] c) RRC connection maximum number ≥ cell supported user number, and uplink PRB utilization rate, downlink PRB utilization rate, and CCE occupancy rate are "high", output optimization suggestion: RRC user overruns and utilization rate is also high, and it is suggested to configure parameters of a larger capacity position for observation.
[0098] d) RRC connection maximum number ≥ cell supported user number, and there is a same coverage inter-frequency cell, according to the checking result, the suggestion of starting the load balancing function is output, and whether the subsequent RRC connection maximum number is reduced to the range of the cell supported user number is observed.
[0099] (2) For the problem cell with high utilization rate, whether there is a same coverage inter-frequency cell is checked. According to the following checking results, the corresponding optimization suggestions are output: a) If there is a same coverage inter-frequency cell, check whether the load balancing function is started, if not, start it, and if the effect is not ideal, execute the following b) scheme.
[0100] b) If there are cells with the same coverage but different frequencies and the load rate of the cells with the same coverage but different frequencies is ≤50%, it is recommended to reduce the power of the high-load cells by 3dB so that the cells with the same coverage but different frequencies can support more users.
[0101] c) If no cells with the same coverage but different frequencies are found, other solutions need to be considered, as shown in Table 1.
[0102] 5. Cell expansion: If the capacity of a single-layer network is still insufficient and the expansion criteria are met, cell expansion can be carried out.
[0103] Expansion Recommendation: If, after implementing the aforementioned optimization recommendations, the frequency with which the cell's PRB utilization exceeds the utilization threshold during the monitoring period meets the expansion criteria (e.g., at least 5 days a week with "at least 5 times a day the cell's PRB utilization exceeds 80%)", then carrier expansion is recommended. Alternatively, if the operator's expansion criteria are met, then the expansion should be implemented according to the operator's criteria.
[0104] 6. The system automatically evaluates and stores the results. It automatically determines whether a cell is in closed loop. Cells that are not in closed loop are continuously reported and alerted, and the optimized solution is output again.
[0105] Closed-loop process: When the average utilization rate of the uplink PRB in the cell is less than 70%, the average utilization rate of the downlink PRB is less than 70%, and the occupancy rate of the PDCCH channel CCE is less than 60%, the cell capacity problem is solved and the cell is closed-loop.
