Description

Base station anomaly self-checking method and device and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for self-checking anomalies in a base station, and a base station.

Background

Various anomalies such as KPI (Key Performance Indicator, key performance indicators) anomalies, terminal failure to access and the like can occur in the operation process of the base station, and the normal network access of the terminal is affected. In order to reduce the influence on the terminal, when the base station is abnormal, the abnormality needs to be found out in time and repaired in time. In the prior art, a base station periodically reports count values of counters corresponding to various performance indexes of itself to an OMC (Operation AND MAINTENANCE CENTER). The OMC is provided with counting thresholds of counters corresponding to various performance indexes, and after the counting values reported by the base station are received, the OMC can compare the counting values with the counting thresholds so as to detect whether the base station is abnormal or not. Therefore, if the base station is abnormal, the base station needs to wait until the base station periodically reports the count value to the OMC next time, and then the abnormality of the base station can be detected through the OMC, so that the abnormality detection of the base station is delayed, and the abnormality detection efficiency of the base station is lower.

In addition, various performance indexes of the base station are affected by the abnormality of the base station, and other factors such as a network environment, the base station reports the count value of the counter corresponding to the various performance indexes to the OMC, and the OMC judges that the base station is abnormal after judging that the count value is abnormal, but the abnormal count value is possibly caused by other factors such as the network environment, so that the possibility of erroneous judgment exists when the base station is judged to be abnormal in the prior art.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention are included in the scope of protection of the present invention.

In order to improve the efficiency of detecting the base station abnormality and improve the accuracy of detecting the base station abnormality, the embodiment of the invention provides a self-checking method and device for the base station abnormality and a base station.

The embodiment of the invention provides a base station anomaly self-checking method which is applied to a base station and comprises the following steps:

Detecting whether an abnormality exists in a target module configured by the base station, wherein the target module comprises at least one of the following modules: FPGA (Field-Programmable GATE ARRAY, programmable logic device), DD (DISK DRIVE, drive), L2 (Radio Link Control, layer 2 radio link control);

Generating an abnormality log recording abnormality information indicating the detected abnormality when the abnormality of the target module is detected;

and reporting the exception log to an OMC (Operation AND MAINTENANCE CENTER) through an OM (Operation AND MAINTENANCE, operation maintenance) unit running in the base station.

Referring to fig. 1, a flow chart of a first base station anomaly self-checking method provided by an embodiment of the present invention is applied to a base station, and the method includes the following steps S101 to S103.

S101: and detecting whether the target module configured by the base station is abnormal.

Wherein the target module comprises at least one of the following modules: FPGA, DD, L2.

In one embodiment of the invention, an FPGA detection unit in a base station health check model can be used for detecting whether an FPGA is abnormal, a DD detection unit is used for detecting whether DD is abnormal, and an L2 detection unit is used for detecting whether L2 is abnormal.

Specifically, the manner of detecting the abnormality of the FPGA may be referred to in the following steps A1 to A6, the manner of detecting the abnormality of the DD may be referred to in the following steps B1 to B4, and the manner of detecting the abnormality of the L2 may be referred to in the following steps C1 to C5, which will not be described in detail herein.

S102: and generating an abnormality log for recording abnormality information when abnormality of the target module is detected.

Wherein the abnormality information is used to indicate the detected abnormality.

Specifically, the anomaly information may include: the identity of the target module in which the abnormality occurred, the type of abnormality of the abnormality detected, the time at which the abnormality was detected, the number of times the abnormality occurred in the target module, and the like.

In one embodiment of the present invention, after the base station health check model generates the abnormal log, a log upload notification may be sent to the OM unit running in the base station, and the execution of step S103 is triggered.

S103: and reporting the abnormal log to an OMC through an OM unit running in the base station.

Specifically, after receiving the log uploading notification, the OM unit reports the abnormal log to a preset path in a CDL (Common CHANNEL DATA ) server of the OMC.

In addition, in the prior art, if the base station is abnormal, the operation and maintenance personnel need to analyze a large amount of logs reported by the base station to find that the base station is abnormal, so that the duration of the process of the operation and maintenance personnel for finding the abnormality is long, abnormal deterioration can be caused, and the running risk of the base station is increased. However, in the scheme provided by the embodiment of the invention, the base station can detect the abnormality of the base station in real time, so that the abnormal occurrence of the base station is prevented from being deteriorated.

In addition, in the prior art, the OMC compares the preset counting threshold value with the counting value of the counter reported by the base station to detect whether the base station is abnormal, but in some cases, the base station is abnormal, but the counting value of the counter does not reach the standard corresponding to the preset counting threshold value, so that the OMC determines that the base station is not abnormal, and the base station is abnormal and is missed. For example, the base station sets a counter to count RRC (Radio Resource Control ) establishment success rate, where the RRC establishment success rate is a number of times of radio resource link establishment success divided by a number of times of radio resource link establishment request, and the base station reports the RRC establishment success rate to the OMC, where the OMC sets an RRC establishment success rate threshold to 30%, determines that the base station is abnormal if the RRC establishment success rate is lower than 30%, but for a probabilistic access problem, if the base station is abnormal, but the RRC establishment success rate is not lower than 30%, the OMC cannot detect that the base station is abnormal. However, in the scheme provided by the embodiment of the invention, the base station can carry out detailed abnormality detection on each module of the base station, so that the problem of abnormality omission can be avoided.

In one embodiment of the present invention, in the case where the target module is an FPGA, whether the FPGA is abnormal may be detected through at least one of the following steps A1 to A6.

Step A1: counting abnormal PCIE (PERIPHERAL COMPONENT INTERCONNECT-Express, internal bus transmission interface) link times of PCIE link abnormality between the CPU and the FPGA of the base station, and if the abnormal times of the PCIE link reach a preset PCIE link abnormality threshold, determining that the PCIE link abnormality exists.

Specifically, the base station may detect whether the CPU of the base station and the PCIE link before the FPGA are abnormal by using a PCIE link state detection task in the FPGA detection unit, if the PCIE link should work normally under the condition that the base station works normally, the count value of a counter corresponding to the PCIE link state detection task is added by 1 each time the PCIE link is abnormal, if the count value of the counter reaches a preset PCIE link abnormality threshold, it is determined that the PCIE link is continuously abnormal, and it is determined that the PCIE link is abnormal.

Step A2: and detecting whether the bottom layers of the electric ports of the base band plate of the base station are synchronous or not, and if the bottom layers are not synchronous, determining that the electric ports of the base band plate are not synchronous, otherwise, determining that the electric ports of the base band plate are abnormal.

Specifically, the base station can detect whether the electric port bottom layer of the back plate of the base station is synchronous by adopting a back plate electric port synchronous detection task in the FPGA detection unit, and the electric port bottom layer of the back plate of the base station is synchronous under the condition that the base station works normally, so that an abnormal signal is output if the electric port bottom layer of the back plate of the base plate is not synchronous, and the abnormal state of the back plate electric port is determined. And writing the number of the abnormal asynchronous times of the backboard electric port into an abnormal log for counting the number of the abnormal asynchronous times of the backboard electric port.

Step A3: and respectively detecting whether each optical port bottom layer on the baseband board is in place and synchronous, and if any optical port bottom layer is out of place or asynchronous, determining that the optical module is abnormal.

Specifically, the base station can detect whether the bottom layers of the optical ports on the base band plate of the base station are in place and synchronous by adopting an optical module state detection task in the FPGA detection unit, a plurality of optical ports exist on the base band plate, and the base station can detect whether the bottom layers of each optical port are in place and synchronous by adopting different registers respectively. When the base station works normally, each optical port bottom layer should be in place and synchronous, and if any optical port bottom layer is out of place or out of synchronous, the existence of the abnormality of the optical module is determined. And writing the number of times of the optical module abnormality of each optical port into an abnormality log for counting the number of times of the optical module abnormality of the optical port.

Step A4: detecting the temperature of the board, and if the temperature of the board is larger than a preset temperature threshold, determining that the temperature of the board is abnormal.

Specifically, the base station may detect the board temperature of the baseband by using a board temperature detection task in the FPGA detection unit, and if the detected board temperature is greater than a preset temperature threshold, it indicates that the board is in a high temperature state, and it is determined that the board temperature is abnormal. And the number of abnormal board temperature times is written into an abnormal log for counting the number of abnormal board temperature times.

Step A5: and detecting whether the frame header sent by the FPGA receiving EPLD (Erasable Programmable Logic Device) has jitter, and if so, determining that the jitter of the frame header of the main control board and the baseband board is abnormal.

Specifically, the base station can detect whether the 80ms frame head sent by the EPLD received by the FPGA by adopting a frame head jitter detection task in the FPGA detection unit has jitter, if the base station works normally, the 80ms frame head sent by the EPLD received by the FPGA has no jitter, and therefore if the frame head has jitter, the main control board and the base band board are determined to have abnormal frame head jitter. And writing the times of frame head jitter abnormality of the main control board and the baseband board into an abnormality log for counting the times of frame head jitter abnormality of the main control board and the baseband board.

Step A6: and detecting whether the field numbers between the CPU and the FPGA are consistent, and if not, determining that the inconsistency abnormality exists between the CPU and the field numbers of the FPGA.

Specifically, the base station can detect whether the field number between the CPU of the base station board card and the FPGA is consistent by adopting the field number detection task in the FPGA detection unit, and can determine the field number of the CPU and the field number of the FPGA respectively, and the field number detection task should be consistent when the base station normally operates. If the CPU and the FPGA field number are inconsistent, determining that the CPU and the FPGA field number are inconsistent and abnormal. And the number of times of abnormal occurrence of inconsistent CPU and FPGA field number is written into an abnormal log for counting the number of times of inconsistent CPU and FPGA field number.

In another embodiment of the present invention, in the case that the target module is a DD, whether the DD has an abnormality is detected through at least one of the following steps B1 to B4.

Step B1: detecting the operation states of the S1 port and the internal port between the base station and the core network, and if the duration of the state of continuously being in the non-packet-receiving task reaches the first preset duration, determining that the port is abnormal.

Specifically, the base station may detect whether the S1 port and the internal port of the base station receive the data packet by using the port detection task in the DD detection unit, and under the condition that the base station is working normally, the S1 port and the internal port of the base station continuously receive the data packet, so if the duration that the S1 port or the internal port is continuously in the state without the packet receiving task reaches the first preset duration, it is indicated that the S1 determines that the port is abnormal.

For example, the first preset time period may be 10 minutes.

And writing the number of port abnormality into an abnormality log for counting the number of port abnormality.

Step B2: detecting the memory use condition of the base station, and if the memory has no free space, determining that the memory is abnormal.

Specifically, the base station may continuously monitor the memory usage of the memory in the base station by using the memory detection task in the DD detection unit, in theory, the memory of the base station may not be fully occupied under the condition that the process of the base station is normally running, if there is no free space in the memory of the base station, it is indicated that the process currently running in the base station has fully occupied the memory of the base station, the process of the base station may have abnormal running, or the memory itself has a fault, and it is determined that there is a memory abnormality.

Under the condition that the memory abnormality exists, if the duration of the free space in the memory reaches the fifth preset duration, the memory of the base station can be determined to be in an abnormal state for a long time. For example, the fifth preset time period may be 1 minute, 3 minutes, 5 minutes, or the like.

And writing the number of memory exceptions into an exception log for counting the number of memory exceptions.

Step B3: detecting the CPU occupancy rate of the base station, and if the duration time when the CPU occupancy rate reaches the preset occupancy rate threshold reaches the second preset duration time, determining that the CPU abnormality exists.

Specifically, the base station may continuously monitor the occupancy rate of the soft core CPU in the base station by using the CPU detection task in the DD detection unit, in theory, the occupancy rate of the CPU of the base station will not be too high under the condition that the process of the base station is running normally, if the occupancy rate of the CPU of the base station reaches the threshold of the preset occupancy rate, it is indicated that the current occupancy rate of the CPU of the base station is higher, if the duration time that the occupancy rate of the CPU reaches the threshold of the preset occupancy rate reaches the second preset duration, it is indicated that the occupancy rate of the CPU of the current base station is higher continuously, then the process of the base station may have abnormal running, or the CPU itself has faults, and it is determined that there is abnormal CPU.

For example, the preset occupancy threshold may be 95%, and the second preset duration may be 1 minute.

In addition, when it is determined that there is a CPU abnormality, information of a task whose CPU occupancy ranking is located at a top preset ranking may be recorded as abnormality information in an abnormality log. For example, the preset ranking may be the first three.

And, the number of CPU abnormality is written into the abnormality log for counting the number of CPU abnormality.

Step B4: detecting the running state of each task running in the base station, and if the duration of any one task running is up to a third preset duration, determining that the task running is abnormal.

Specifically, the base station may detect the task by using the task state in the DD detection unit, periodically detect the running state of the task being executed, and if the duration of any task in the non-running state reaches the third preset duration, it indicates that there may be an operation failure in the task, and determine that there is a task running abnormality.

For example, the third preset time period may be 10 minutes.

And writing the number of task operation abnormality into an abnormality log for counting the number of task operation abnormality.

In one embodiment of the present invention, in the case where the target module is L2, whether the L2 is abnormal is detected through at least one of the following steps C1 to C5.

Step C1: counting the broadcast failure times of the base station which does not successfully broadcast SIB1 (System Information Block Type1, system message) at the preset time, and if the broadcast failure times reach the preset time threshold, determining that the broadcast message transmission failure abnormality exists.

Specifically, the base station may preset the time for broadcasting SIB1, and if the base station operates normally, the base station will broadcast SIB1 at the preset time, so if the base station does not successfully broadcast SIB1 at the preset time, it is indicated that the base station may have an abnormality. The base station adopts a broadcast message detection task in the L2 detection unit to detect whether the base station successfully broadcasts SIB1 at a preset time, and adopts a counter to count the broadcast failure times of SIB1 failure, if the broadcast failure times reach a preset time threshold, the base station is determined to broadcast SIB1 for a plurality of times, and if the broadcast failure times are determined to have abnormal broadcast message transmission failure.

Step C2: detecting whether a frame number of msg1 (message 1) reported to the base station by a terminal in the process of gradually increasing a power transmitting probe is synchronous with a frame number of a BCP (Bit processor) of a baseband in the base station, and if not, determining that the frame number is abnormal in asynchronous.

The process of reporting msg1 to the base station by the terminal is in the prior art, and the embodiment of the present invention will not be described herein.

Specifically, if the base station operates normally, the frame number of msg1 reported by the base station and the frame number of BCP of the baseband in the base station will keep synchronous, so if the frame number of msg1 and the frame number of BCP are not synchronous, it is determined that there is an abnormal frame number non-synchronization. The base station may detect whether the frame number of msg1 is synchronized with the frame number of BCP using the frame number synchronization detection task in the L2 detection unit.

In one embodiment of the present invention, the prior art may be used to detect whether the frame number of msg1 and the frame number of BCP are synchronous, where a detection result of 0 indicates that the two are synchronous, and other values except for 0 indicate that the two are not synchronous.

In addition, the number of times that the frame number out-of-sync abnormality occurs in the base station may be counted using a counter corresponding to the frame number out-of-sync abnormality.

Step C3: and detecting whether the msg2 sent by the base station in the process of replying to ACK (acknowledgement message) after receiving the msg1 has the condition of a super window, and if the number of continuous super windows reaches the preset number of times, determining that the msg2 has the abnormal super window.

Specifically, under the condition that the base station is in normal operation, the msg2 sent by the base station does not have the condition of the super window, so if the condition that the msg2 has the super window, it can be determined that the msg2 super window is possibly abnormal. The base station can detect whether the msg2 has the condition of the super window by adopting an msg2 super window detection task in the L2 detection unit, and if the number of times of the detected continuous super window reaches the preset number of times, the msg2 super window abnormality is determined.

The base station is provided with a counter corresponding to the msg2 super-window detection task, and the count value of the counter is incremented by 1 every time the msg2 super-window detection task detects an msg2 super-window abnormality, so that the occurrence frequency of the msg2 super-window abnormality can be counted as a part of abnormality information.

Step C4: and counting the failure times of establishing the communication link between the base station and the terminal, and if the failure times reach the preset times, determining that the abnormal link establishment exists.

Wherein the communication connection comprises at least one of the following links: MAC (Medium Access Control ) uplink, MAC downlink, CCH (Commontransport Channel ) link, random access link.

Specifically, under the condition that the base station operates normally, the communication link between the base station and the terminal can be successfully established, and if the communication link between the base station and the terminal fails to be established, the base station is determined to be abnormal.

In one embodiment of the present invention, for each communication link of the MAC uplink, the MAC downlink, the CCH link, and the random access link, the base station may use a communication link detection task in the L2 detection unit to detect whether the communication link is successfully established between the base station and the terminal, and if any link establishment fails, determine that the base station has a link establishment abnormality. And, for each type of communication link, the number of times of creating failure of the type of communication link can be counted as a part of the abnormal information.

And, the number of times of occurrence of the link establishment abnormality of the base station can be counted by adopting a counter corresponding to the link establishment abnormality.

Step C5: after the base station receives the switching request reported by the terminal, if msg1 reported by the terminal is not received within a fourth preset duration, determining that switching abnormality exists.

Specifically, after receiving a handover request reported by a terminal, a base station sends a link establishment instruction indicating to create a communication link with the terminal to L2 by HL (HIGH LAYER, higher layer), the base station can count the number of times that the msg1 is received by the L2 in a handover waiting period, and if the base station does not receive any msg1 reported by the terminal until the waiting period is over before deleting an identification preamble (random access preamble) of the terminal, the base station determines that a handover abnormality exists.

The base station may detect whether or not there is a switching abnormality using a switching detection task in the L2 detection unit, and be provided with a counter corresponding to the switching detection task, the count value of which is incremented by 1 every time a switching abnormality is detected, thereby counting the number of occurrences of the switching abnormality as a part of the abnormality information.

Referring to fig. 2, a functional schematic diagram of a base station health check model according to an embodiment of the present invention is provided.

As can be seen from the figure, the base station health check model includes FGPA detection unit, DD detection unit, and L2 detection unit.

The FPGA detection unit can execute PCIE link state detection tasks, backboard electric port synchronous detection tasks, optical module state detection tasks, board card temperature detection tasks, frame head jitter detection tasks and field number detection tasks.

The DD detection unit can execute a port detection task, a memory detection task, a CPU detection task and a task state detection task.

The L2 detection unit is capable of performing a broadcast message detection task, a frame number synchronization detection task, an msg2 super window detection task, a communication link detection task, and a handover detection task.

Specifically, specific functions of each detection unit and each task in the figure are described in the foregoing, and are not described herein.

Referring to fig. 3, a flow chart of a second base station anomaly self-checking method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1, the method further includes the following steps S104-S105.

S104: determining whether the number of detected anomalies exceeds an anomaly number threshold corresponding to the anomaly.

Specifically, different anomaly frequency thresholds may be set for each anomaly of each target model. Different anomalies have different degrees of influence on the base station, different anomaly frequency thresholds corresponding to different anomalies are different, and the anomaly frequency threshold corresponding to the anomaly with higher influence on the base station is smaller, so that the anomaly with higher influence can trigger the execution step S105 to reset the base station under the condition of fewer times, and the base station can timely control the anomalies. In contrast, the threshold of the number of anomalies corresponding to the anomaly with the lower influence degree on the base station is larger, so that the base station can be prevented from being triggered to execute the step S105 to reset to influence the normal operation of the base station after the anomaly with the lower influence degree occurs.

The statistics of the number of each anomaly may be found in the previous descriptions of steps A1-A6, B1-B4 and C1-C5, which will not be repeated.

S105: and if the abnormal times exceeds the abnormal times threshold, resetting the base station by adopting a preset resetting mode corresponding to the detected abnormality.

Specifically, reset modes corresponding to different anomalies may be preset, where the reset modes include: the method comprises the steps of resetting a processor, resetting a board card and resetting a base station, and resetting the base station by adopting different resetting modes aiming at different anomalies, so that the anomalies of the base station are repaired.

From the above, in the scheme provided by the embodiment of the invention, the base station can self-detect the self-abnormality, and can reset the base station in a mode corresponding to the generated abnormality after determining the self-abnormality, so that the base station can directly repair the self-abnormality, the normal operation of the base station is prevented from being greatly influenced by the abnormality, maintenance personnel are not required to manually process the process, and the efficiency of repairing the abnormality of the base station can be improved.

Referring to fig. 4, a flow chart of a third method for self-checking abnormal base station according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1, the above step S103 may be implemented by the following steps S103A-S103C.

S103A: and determining whether the value of the uploading identifier corresponding to the recorded target abnormal type is a first preset value.

Wherein, the target exception types are: the type of the abnormality existing in the detected target module, the value of the uploading identifier is represented by a first preset value: and the base station reports the abnormality log of the abnormality type corresponding to the uploading identifier in a preset period.

Specifically, each of the foregoing abnormality detection in steps A1-A6, steps B1-B4, and steps C1-C5 corresponds to an abnormality type, and for each abnormality type, the base station is provided with an upload identifier corresponding to the abnormality type, and if the value of the upload identifier is a first preset value, it indicates that the base station has reported an abnormality log of the abnormality type corresponding to the upload identifier. For example, the first preset value is 1, and under the condition that the value of the uploading identifier is 1, determining that the base station has reported the exception log of the exception type corresponding to the uploading identifier in a preset period, otherwise, determining that the base station has not reported the exception log of the exception type corresponding to the uploading identifier in the preset period.

In one embodiment of the present invention, after detecting an abnormality and generating an abnormality log, the base station health inspection model may send a log reporting notification to the OM unit, and after receiving the log reporting notification, the OM unit may determine whether the value of the reporting identifier corresponding to the target abnormality type is a first preset value.

If not, step S103B is executed, otherwise, the exception log is not uploaded to the OMC, and the process is ended.

S103B: and reporting the abnormal log to an OMC through an OM unit running in the base station, and updating the value of the uploading identifier corresponding to the target abnormal type to the first preset value.

If the target exception type is not the first preset value, the base station does not upload the exception log of the target exception type in the preset period, the OM unit may report the exception log to the OMC, and update the value of the upload identifier corresponding to the target exception type to the first preset value, which indicates that the exception log of the target exception type has been reported in the preset period.

S103C: and updating the value of the uploading identifier corresponding to each abnormal type to a second preset value according to the preset period.

Wherein the second preset value is different from the first preset value.

In one embodiment of the present invention, the OM unit may create a log report timer that repeatedly counts according to the duration of the preset period. And after the preset period, the OM unit updates the value of the uploading identifier corresponding to each abnormal type to a second preset value different from the first preset value, which is equivalent to clearing the report record of the abnormal log corresponding to each abnormal type, so that the OM unit can upload the abnormal log of each abnormal type again in the next preset period.

In each preset period, the OM unit only reports to the OMC at most once for each exception log of each exception type.

From the above, since the abnormality may be difficult to repair in a short time after the abnormality occurs in the base station, the base station may continuously monitor the abnormality in a short time and continuously generate the abnormality logs, the generated abnormality logs are caused by the same abnormality, the information recorded in the abnormality logs is similar, if the OM unit sends all the generated abnormality logs to the OMC, a large number of similar abnormality logs are sent, and a large amount of data transmission resources are wasted. In the scheme provided by the embodiment of the invention, aiming at the abnormal logs of each abnormal type, the OM unit only reports the abnormal logs to the OMC at most once, so that the problem of repeated reporting of similar abnormal logs can be avoided, and the data transmission resources are saved.

S504: the base station health check model sends log upload notifications to the OM unit.

S505: the OM unit judges whether an abnormality log corresponding to the detected abnormality is reported to the OMC in a preset period.

If the exception log corresponding to the detected exception has been reported, the exception log is not reported to the OMC. If the abnormality log corresponding to the detected abnormality is not reported, step S506 is executed.

In an embodiment of the present invention, whether an exception log corresponding to the detected exception has been reported may be determined according to whether the value of the uploading identifier of the target exception type corresponding to the detected exception is the first preset value, and a specific implementation manner may refer to the embodiment of fig. 4 and will not be described herein.

S506: and the OM unit reports the abnormal log to a preset path in the CDL server of the OMC under the condition that the abnormal log corresponding to the detected abnormality is not reported.

S507: and the OM unit updates the value of the uploading identifier corresponding to the target abnormal type to a first preset value.

S508: and the OM unit updates the value of the uploading identifier corresponding to each abnormal type to a second preset value after the timing of the log reporting timer reaches the duration of the preset period.

S509: the base station health check model sets an anomaly frequency threshold corresponding to various anomalies.

S510: and if the abnormal times of the detected abnormality exceeds the abnormal times threshold corresponding to the abnormality, resetting the base station by the base station health check model.

The specific implementation manner of steps S501-S510 may be referred to the foregoing embodiments, and will not be described herein.
