Description

Technical Field

[0002] To facilitate the transmission of radio signals between the network side of a mobile communication system and mobile phone terminals, radio transceiver stations, also known as public mobile communication base stations or field base stations, are established. During prolonged operation, field base stations may experience hardware or software failures, leading to cell malfunctions or anomalies that prevent them from providing normal service to users; in other words, the cell may experience an abnormal operating state.

[0003] Currently, the main method for monitoring cell faults or anomalies is to collect cell operation status information from the base station, obtain alarm information issued by the base station, and notify maintenance personnel that the cell is in an abnormal operating state. The maintenance personnel then take relevant actions to restore the cell to normal operation. However, by the time maintenance personnel become aware of a cell fault or anomaly, some time may have passed, resulting in an inability to address the problem promptly.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] Figure 1 This is one of the flowcharts illustrating the cell anomaly detection and recovery method provided in this application embodiment. The following is a combination of... Figure 1 The method for cell anomaly detection and recovery provided in this application includes:

[0066] Step 110: Monitor the operation status of the community according to the set monitoring indicators, and determine the operation status of the community based on the monitoring results;

[0067] Specifically, in this embodiment of the application, specific indicators statistically analyzed by the base station operation and maintenance system are effectively monitored, and monitoring indicator thresholds are set. When the value of a specific indicator is compared with the set monitoring indicator threshold, an indicator abnormality is determined.

[0068] Step 120: When it is determined that the cell needs to perform cell anomaly self-recovery, perform cell anomaly self-recovery according to the cell anomaly self-recovery configuration mode.

[0069] Specifically, in this embodiment of the application, when it is determined that the cell's working status is abnormal, a self-recovery method is used to restore the cell to its normal working status and continue to provide normal services to users.

[0070] In one embodiment, a cache table, such as a cell anomaly monitoring table, is first added to the base station's internal database to record the cell's operational status. In another embodiment, specific statistical indicators obtained by monitoring the base station's operation and maintenance system are cached in the cell anomaly monitoring table. Set monitoring indicator thresholds can also be cached in the cell anomaly monitoring table. The specific statistical indicators are compared with the monitoring indicator thresholds to determine whether the threshold conditions are met, thereby determining whether cell anomaly self-recovery needs to be performed.

[0071] In another embodiment, a new node and a switch are added to the base station operation and maintenance system to indicate the cell anomaly judgment and recovery method provided in this application. When the switch is open, the cell anomaly judgment and recovery method provided in this application is implemented; when the switch is closed, the original process is performed.

[0072] The above processing can be implemented in software or in hardware that is functionally equivalent to software. The two are logically equivalent. The hardware implementation is more efficient, while the software implementation is more flexible. When the hardware cost is low, the hardware implementation can be chosen.

[0073] In one embodiment, specific statistical indicators of the base station operation and maintenance system are monitored according to a predetermined period, and the specific statistical indicators are compared with the monitoring indicator threshold according to another predetermined period. The aforementioned period is in the form of a clock cycle, or in natural time units such as seconds, minutes, and hours. The aforementioned period enables timely judgment of whether a cell has a fault or abnormality, and timely restoration of the cell to normal working status, reducing or avoiding the inability to provide normal services to users.

[0074] Optionally, the monitoring indicators set include: the number of S1 Evolved Radio Access Bearer (ERAB) establishment requests corresponding to the cell, the S1 ERAB establishment success rate corresponding to the cell, and the downlink block error rate of the Medium Access Control (MAC) layer corresponding to the cell.

[0075] Specifically, the criterion for determining whether a cell is in an abnormal operating state can be selected from the cell's S1 ERAB (Evolved Radio Access Bearer) establishment success rate, which can be achieved by monitoring one or more of the cell's S1 ERAB establishment success rate and the downlink block error rate of the MAC layer corresponding to the cell. In some embodiments, other statistical indicators can also be selected as the criterion for determining an abnormal operating state.

[0076] The above statistical indicators can be used to determine in a timely manner whether a community is in an abnormal operating state, thus avoiding redundant procedures.

[0077] Optionally, the monitoring indicator thresholds can be set as follows: S1 ERAB establishment request count threshold, S1 ERAB establishment success rate threshold, and MAC layer downlink block error rate threshold. The cell is judged to be in an abnormal operating state by comparing the statistical indicators with the monitoring indicator thresholds.

[0078] Specifically, when the number of S1 ERAB establishment requests exceeds the S1 ERAB establishment request number threshold, the S1 ERAB establishment success rate is less than the S1 ERAB establishment success rate threshold, and the MAC layer downlink block error rate is greater than the MAC layer downlink block error rate threshold, the cell is determined to be in an abnormal operating state.

[0079] That is, when the comparison results show that the above statistical indicators reach the monitoring indicator threshold at the same time, the cell is in an abnormal operating state. The cell can be restored to normal working state in a timely manner by executing the cell abnormal self-recovery, so as to provide normal services to users.

[0080] The above-mentioned statistical and monitoring threshold settings enable timely detection of abnormal working conditions in the community and trigger the community's self-recovery from the anomaly.

[0081] Optionally, to avoid frequent triggering of cell anomaly self-recovery, or even unlimited self-recovery, which would affect the normal service provided to users, some statistical indicators can be added, namely, cell anomaly self-recovery control parameters. Only when the cell anomaly self-recovery control parameters are further met can it be determined that the cell can perform cell anomaly self-recovery.

[0082] Specifically, in this embodiment of the application, the set monitoring indicators may further include: the number of times the cell is in an abnormal operating state within a preset period; and the number of times the cell performs cell abnormal self-recovery within a preset period.

[0083] Based on the above scheme, by counting the number of times cell anomalies occur and the number of times cell anomaly self-recovery is performed, the frequent triggering of cell anomaly self-recovery, or even unlimited self-recovery, can be avoided.

[0084] Accordingly, determining the operational status of the community based on monitoring results includes:

[0085] When a cell is determined to be in an abnormal operating state, and the number of times the cell is in an abnormal operating state within a preset period is greater than or equal to a threshold number of times the cell is in an abnormal operating state within a preset period, and the number of times the cell performs cell abnormal self-recovery within a preset period is less than a threshold number of times the cell performs cell abnormal self-recovery within a preset period, it is determined that the cell needs to perform cell abnormal self-recovery.

[0086] Specifically, in this embodiment of the application, when a cell is determined to be in an abnormal operating state, the number of times the cell is in an abnormal operating state within a preset period is compared with a threshold for the number of times the cell is in an abnormal operating state, and the number of times the cell performs cell abnormal self-recovery within the preset period is compared with a threshold for the number of times the cell performs cell abnormal self-recovery; when the number of times the cell is in an abnormal operating state is greater than or equal to the threshold for the number of times the cell is in an abnormal operating state and the number of times cell abnormal self-recovery is performed is less than the threshold for the number of times self-recovery is performed, it is determined that the cell needs to perform cell abnormal self-recovery.

[0087] In one embodiment, the preset period can be one calendar day, or it can be a multiple of the monitoring period. The preset period enables timely determination of whether the cell needs to perform abnormal self-recovery, while avoiding excessive number of abnormal self-recovery operations.

[0088] Optionally, considering different scenario requirements, appropriate cell anomaly self-recovery configuration modes can be set to effectively resolve the problem without consuming excessive time and energy. In one embodiment of this application, four cell anomaly self-recovery configuration modes are designed: resetting the RRU (Remote Radio Unit) where the cell resides; resetting the baseband board where the cell resides; deactivating and then reactivating the cell; and resetting the base station where the cell resides. One or more of the above anomaly self-recovery configuration modes can be selected as needed to perform cell anomaly self-recovery.

[0089] In one embodiment, priorities can be set for each abnormal self-recovery configuration mode based on the time consumed. For example, when all four configuration modes are selected, the priority order of each configuration mode from high to low is: deactivate and then reactivate the cell; reset the RRU where the cell is located; reset the baseband board where the cell is located; reset the base station where the cell is located.

[0090] That is, the configuration mode of first deactivating and then activating the cell can correct the cell signal and restore the cell to normal working status in a short time.

[0091] If the cell fails to return to normal operation after completing the cell anomaly self-recovery according to the cell deactivation and reactivation configuration mode, the RRU configuration mode of the cell is reset is selected first. This configuration mode will not affect the transmission and reception of other radio frequency signals, but will only recalibrate the transmission and reception of the radio frequency signals of the abnormal cell.

[0092] If the cell fails to return to normal operation after performing cell anomaly self-recovery according to the above two configuration modes, the configuration mode of resetting the baseband board where the cell is located will be selected first. This configuration mode will reconnect the RRU connected to the current baseband board and calibrate the transmitted baseband signal, and modulate the calibrated baseband signal onto the radio frequency signal and retransmit it.

[0093] Finally, if normal operation cannot be restored, select the configuration mode of the base station where the cell is located. This configuration mode can initialize all systems and clear all anomalies.

[0094] The above-mentioned cell anomaly self-recovery is performed sequentially according to the priority of each configuration mode until the cell's operating status returns to normal, allowing for cell anomaly self-recovery with minimal time and energy consumption, and restoring the cell's operating status to normal as quickly as possible. Of course, other self-recovery configuration modes and corresponding priority orders can also be set according to application needs.

[0095] Figure 2This is the second flowchart of a cell anomaly detection and recovery method based on an embodiment of this application. The following is a combination of... Figure 2 This application describes a method for cell anomaly detection and recovery provided by one embodiment.

[0096] First, specific indicators of the base station operation and maintenance system are periodically monitored. When the sampling interval is reached, the performance statistics are collected and reported.

[0097] The next node in the base station operation and maintenance system provided in this application embodiment indicates whether the cell anomaly judgment and recovery method provided in this application is adopted, that is, whether the cell anomaly detection switch is turned on. When the switch is turned off, the original process is followed, and the entire process of the cell anomaly judgment and recovery method provided in this application embodiment ends; when the switch is turned on, the process of the cell anomaly judgment and recovery method provided in this application embodiment continues.

[0098] When the switch is turned on, all existing cells are polled to check if the current status of the cells is available. If the cell is available, also known as active, the S1 ERAB establishment success rate monitoring index of the corresponding cell is extracted to determine whether the judgment condition is met. The first step is to determine whether the cell needs to perform cell anomaly self-recovery. Otherwise, it is determined that the cell does not perform cell anomaly self-recovery and the step of clearing the daily consecutive anomaly count statistics of the cell is taken.

[0099] The first step in determining whether a cell needs to perform cell anomaly self-recovery involves checking if the "S1 ERAB establishment request count" is greater than a threshold, and then checking if the S1 ERAB establishment success rate is lower than a threshold. If the S1 ERAB establishment success rate is lower than the threshold, the next step is to check if the MAC layer downlink block error rate is greater than a threshold. If the MAC layer downlink block error rate is also greater than the threshold, all three conditions for comprehensive judgment are met. In this case, the number of consecutive anomalies for the day is increased by one, and the process proceeds to the second step in determining whether the cell needs to perform cell anomaly self-recovery. Otherwise, the cell is determined not to need to perform cell anomaly self-recovery, and the process proceeds to clear the daily consecutive anomaly count statistics.

[0100] The second process for determining whether a cell needs to perform cell anomaly self-recovery includes the following conditions: if the number of consecutive anomalies in a cell on a given day is greater than or equal to the threshold for consecutive detections of the cell's S1 ERAB establishment success rate, and the number of resets on the day of cell self-healing is less than the threshold for the maximum number of resets on the day of the cell's S1 ERAB establishment success rate, then the cell needs to perform cell anomaly self-recovery. The cell anomaly self-recovery is then performed according to the cell anomaly self-recovery configuration mode. Otherwise, the process returns to polling all existing cells.

[0101] Perform the corresponding cell anomaly self-recovery operations according to the cell anomaly self-recovery configuration mode, including:

[0102] 1) Reset the remote radio unit (RRU) where the cell is located, and increase the number of resets for the day of cell self-healing by one;

[0103] 2) Reset the baseband board where the cell is located, and increase the number of resets for the day of cell self-healing by one;

[0104] 3) Deactivate and then reactivate the cell to increase the number of times the cell has been reset on the same day for self-healing;

[0105] 4) Reset the base station where the cell is located, and increase the number of resets for the day of cell self-healing by one.

[0106] The next step is to clear the number of consecutive abnormal occurrences for the day in the community, and reset the number of consecutive abnormal occurrences for the day in the community to zero.

[0107] After the entire station is reset, it is not necessary to enter the step of clearing the daily consecutive abnormal number statistics of the cell, but to directly enter the step of determining whether all cells have been processed.

[0108] One or more cell anomaly self-recovery configuration modes can be selected according to actual needs, or the cell anomaly self-recovery configuration mode can be selected by setting the priority of each anomaly self-recovery configuration mode according to the time consumed, as mentioned in the above embodiments.

[0109] Once a cell returns to normal operation, it is determined whether all cells have completed the process. If so, the process of the cell anomaly judgment and recovery method provided in this application embodiment ends; otherwise, it returns to polling all existing cells. A tag can be set for cells that have already been processed or determined not to require cell anomaly self-recovery, so that the operation of polling all cells is not repeated.
