Detailed Description

How to efficiently and conveniently carry out automatic troubleshooting on a base station is a topic which needs to be researched. If there is a better method of handling, then the labor costs are reduced and customer satisfaction is improved.

In the related art, when a system fault occurs in a base station, each subsystem generally reports an alarm to notify maintenance personnel, and the maintenance personnel can perform fault removal detection and processing according to prompts in alarm information and submit problem work orders at the same time.

However, the limitations of human troubleshooting alarms exist: 1. each alarm reason cannot be carefully checked; 2. when multi-problem triggering is faced, the processing priority is difficult to make correct judgment in a short time; 3. the handling of emergency problems requires the examination of the skill and experience of the troubleshooting personnel; 4. the serious fault problem can not be processed at any time, and the troubleshooting timeliness is difficult to grasp.

Therefore, the embodiment of the application provides a method and a device for processing the fault of the base station and a storage medium.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A method, an apparatus, and a storage medium for handling a failure of a base station according to an embodiment of the present application are described below with reference to the drawings.

Fig. 1 is a flowchart of a method for processing a failure of a base station according to an embodiment of the present application.

The execution main body of the fault processing method of the base station in the embodiment of the application is the base station or a terminal in the base station.

As shown in fig. 1, the method for processing a failure in a base station includes:

step S101, acquiring a fault code of the base station.

It should be noted that a fault code (also referred to as a fault number) may be understood as a code or a number indicating a fault of a base station, a fault of a base station may be in a one-to-one correspondence relationship with a fault code, and a fault code may be composed of numbers and/or letters, for example, a fault corresponding to the fault code "1104" may be "the radio frequency unit is not in place".

In the embodiment of the application, in order to deal with various complex problems of the whole network, a processing scheme which can store the database processed after the alarm fault as comprehensively as possible is required. Therefore, the alarm processing information provided by the existing research and development is taken as a base line, and the processing schemes and the classical cases of various problems of a laboratory and an external field are combined for perfection to form a database for fault judgment.

According to the embodiment of the application, the fault code corresponding to each fault can be constructed in advance based on any possibly-occurring faults of the base station, and the faults and the corresponding fault codes can be stored in the database so as to call the database when the base station fails.

Specifically, when the base station fails, the database may be called after the failure is analyzed, so as to obtain a failure code corresponding to the failure occurring in the base station in the database.

And step S102, acquiring a first fault processing scheme corresponding to the fault code according to the fault code of the base station.

It should be noted that the first fault handling scheme may be understood as a fault handling scheme corresponding to the acquired fault code, where the fault handling scheme may be understood as a scheme that can solve a fault or eliminate a fault, for example, the suitable fault handling scheme when the baseband processor of the base station fails due to long-time operation may be to perform reload start.

According to the embodiment of the application, the fault processing schemes can be determined in advance according to any possibly-occurring faults of the base station, wherein the faults and the fault processing schemes can be in a one-to-one correspondence relationship, namely, the fault codes and the fault processing schemes can be in a one-to-one correspondence relationship.

Specifically, after the fault code of the base station is obtained, the first fault handling scheme corresponding to the fault code may be obtained according to the fault code.

And step S103, carrying out fault processing on the base station according to the first fault processing scheme.

Specifically, after acquiring the first failure handling scheme, in order to resolve the failure, the base station may be failure handled according to the first failure handling scheme. In the embodiment of the application, an automatic processing script can be set so as to call the script when a fault occurs, and a flow processing scheme is formed. Meanwhile, if a new processing scheme exists, the new processing scheme is embodied in the work order and is supplemented and iterated to the database in time after being reviewed by the expert group.

For example, if the baseband processor fails due to long-time operation, the fault code a corresponding to the fault may be acquired, and further, the first fault handling scheme corresponding to the fault code a may be acquired, for example, "reload start," and then the baseband processor may be reloaded to start up to eliminate the fault.

It should be noted that, in base stations in different cities, different times and different scenes, there are many background monitoring personnel needed at present, the efficiency of processing problems every day is low, and the comprehensiveness of processing problems cannot be achieved. In addition, the software in the embodiment of the application can have the capability of machine learning, the calculation of scheme combination is carried out according to the existing processing scheme, an optimization network is formed, and the benefit and disadvantage analysis proportion is given, so that a better development direction is reflected.

And step S104, performing analog reasoning according to the fault code of the base station to determine a second fault handling scheme associated with the fault code under the condition that the fault handling is not effective.

It should be noted that, after the base station is subjected to fault processing according to the first fault processing scheme corresponding to the fault code, the fault may be eliminated or not eliminated, the fault elimination or the base station being normal indicates that the fault processing is effective, and the fault not eliminated indicates that the fault processing is not effective, and at this time, further fault processing is required.

Specifically, after the base station is subjected to the fault processing according to the first fault processing scheme, whether the fault processing is effective or not can be judged, and if the fault processing is effective (that is, the fault is already removed), the process can be exited; if not, i.e. the fault is not resolved, it can first be determined whether there are other causes related to (indirectly) the fault, and if so, an analogous reasoning is performed based on the fault code to determine a second fault handling scheme associated with the fault code.

And step S105, performing fault processing on the base station according to the second fault processing scheme. That is, after the base station is fault-processed according to the first fault processing scheme, if a fault still exists, a second fault processing scheme associated with the fault is acquired to process the base station by adopting the scheme so as to eliminate the fault.

Therefore, according to the fault processing method of the base station, the fault processing scheme corresponding to the fault code is obtained according to the fault code of the base station, so that the base station is subjected to fault processing according to the fault processing scheme, automatic processing of the fault of the base station is achieved, the efficiency of fault processing is improved, the reliability of fault processing is improved, and labor cost can be reduced.

It should be noted that, the database may store attributes corresponding to each fault, such as a category, and when fault codes of the same category appear in the base station, in order to improve efficiency and reliability of fault processing, a log file corresponding to the fault codes may be extracted and stored. The log file may be a file that records an operation log of the base station device related to the fault code.

That is, in an embodiment of the present application, the method for processing a failure of a base station may further include: and extracting and storing a log file corresponding to the fault code according to the fault code of the base station.

Specifically, after the step S101 is executed, if a plurality of acquired fault codes belong to the same category, a log file corresponding to the fault code may be extracted and stored in the database.

For example, when an equipment fault, namely a fault code "1104" - "the radio frequency unit is not in place", a common log of the base station and a corresponding log of the baseband board card need to be saved; when a service fault-fault code "11705" - "L2 super window" occurs, the public log of the base station and the log of number 67 of the corresponding baseband board card need to be saved.

After the log file is acquired, the log file can be saved to a designated directory, meanwhile, the processing priority can be sorted according to the severity of the fault, then, the processing optimal scheme corresponding to the fault can be found in the database, and then, the program can execute the fault removal script in the corresponding database to realize the processing of the base station fault.

That is, when there are a plurality of fault codes of the base station, the step S103 of performing fault processing on the base station according to the first fault processing scheme may include: determining severity information of each fault according to the log file corresponding to each fault code; determining a priority order of the plurality of fault codes according to the severity information; and carrying out fault processing on the base station according to the priority order and the first fault processing scheme.

The severity information may include, among other things, a severity level or severity level of the fault, such as more severe, moderately severe, very severe, etc. It should be noted that the higher the severity level of the fault, the higher the priority of the fault to be handled.

Specifically, when the base station has multiple faults and the multiple faults belong to the same attribute, for example, the category, the fault code corresponding to each fault may be obtained to obtain multiple fault codes, and then the first fault handling scheme corresponding to each fault code is obtained according to the multiple fault codes to obtain multiple first fault handling schemes. And then determining the severity information of each fault according to the log file corresponding to each fault code, further determining the priority order of a plurality of fault codes according to the severity level of each fault, and further executing a plurality of first fault solutions in the base station according to the priority order in sequence until the plurality of first fault solutions are executed.

Therefore, the log files corresponding to the fault codes are stored, the priority order of the faults is favorably determined, and after the priority order of the faults is determined, a plurality of fault solutions can be executed based on the priority order to process the faults of the base station, so that the efficiency and the reliability of the fault processing are improved.

In an embodiment of the present application, as shown in fig. 2, the step S104 may include the following steps S201 to S204.

In step S201, it is determined whether the failure processing is effective.

And step S202, if the fault code is not valid, acquiring a fault positioning point according to the fault code.

The fault locating point can be understood as a fault location point or a fault location point which needs to be extracted during research and development corresponding to the fault, and the fault locating point is determined according to the fault occurrence reason.

Step S203, acquiring a fault association point associated with the fault positioning point.

The fault association point can be understood as a fault location point associated with the fault location point.

And step S204, determining a corresponding second fault processing scheme according to the fault association point.

The second fault handling scheme may be understood as a fault handling scheme corresponding to a fault code corresponding to a fault occurring at the fault association point.

Specifically, after the base station is subjected to the fault processing according to the first fault processing scheme, whether the fault processing is effective or not can be judged, and if the fault processing is effective (that is, the fault is already removed), the process can be exited; if the fault is not effective (namely the fault is not eliminated), whether the fault is caused by other relevant reasons or not can be judged, if the fault is caused, a fault locating point is obtained according to the fault code, a fault associated point associated with the fault locating point is obtained, a corresponding second fault processing scheme is determined according to the fault associated point, and the fault processing is carried out on the base station according to the second fault processing scheme.

That is, after the base station is fault-processed according to the first fault processing scheme, if a fault still exists, a fault code corresponding to an associated fault associated with the fault is acquired, and a second fault processing scheme corresponding to the fault code is acquired to process the base station by adopting the scheme to eliminate the fault.

Further, the step S203 of acquiring a fault association point associated with the fault locating point may include: and acquiring a fault association point associated with the fault positioning point according to the fault logic relationship diagram.

The failure logic relationship graph may refer to an indication graph including a plurality of failures that may occur in the base station and a logic relationship between the failures, and the graph may further include a failure solution corresponding to each failure.

In the embodiment of the application, a fault logic relationship diagram can be constructed in advance based on a plurality of faults which may occur in a base station and corresponding fault processing schemes, and the fault logic relationship diagram is stored.

Specifically, after the step S202 is executed, that is, the fault location point is obtained, the fault logic relationship diagram may be called to obtain the fault association point associated with the fault location point according to the fault logic relationship diagram. And then, determining a corresponding second fault processing scheme according to the fault association point, and carrying out fault processing on the base station according to the second fault processing scheme.

For example, as shown in the logic relationship diagram of fig. 3, which includes failures (r) to (v), the relevant logic is: if the alarm meets the condition I, the program executes a fault processing scheme A to the base station; if the alarm meets the condition II, the program executes a fault processing scheme B to the base station, and if the fault processing scheme III occurs, the fault processing scheme C needs to be executed; if the alarm meets the condition (IV), the program executes a fault processing scheme (D) on the base station; if the alarm satisfies the condition (c), the program will execute the failure processing scheme (E) to the base station.

Meanwhile, in the cause-and-effect relationship of the fault of the database, according to a deduction mode, a fault occurs firstly, which can lead to secondly certainly; a failure (III) can be caused definitely; if a fault occurs, the fault can lead to the fourth step; failure (fifthly), which definitely results in (iv); therefore, the failure occurs (c), and the possible root cause is (c).

The corresponding failure causes and failure solutions of the first to the fifth failures can be seen in table 1, where when the first failure occurs, the failure cause may be an uplink exception (corresponding failure code x1) of an FPGA (Field Programmable Gate Array) or a drive bottom layer is disabled (corresponding failure code x 2).

Table 1 fault and fault handling scheme correspondence table

Fault of	Cause of failure	Fault handling scheme
			①	FPGA uplink exception (x1) or drive bottom dead (x2)	A: heavy load processor
②	Abnormal task suspension	B: restart board card
			③	FPGA Downlink Exception (y1)	C: deactivating and then activating cells
④	FPGA uplink exception (x1)	D: restarting underlying link establishment
			⑤	FPGA uplink exception (x1) and frame number calibration failure (x3)	E: restarting the whole station

In terms of the processing scheme, if the fault is not recovered after the action D executed at time # D, the deduction flow may need to be taken after 2 actions D are executed. The alternatives that can be performed according to the analysis procedure are A, C and E, i.e. the point of failure association that is associated with the failure anchor point can be the processor, the cell and the whole base station. Thereafter, A, C and E may be performed to eliminate the fault.

Therefore, when the first fault processing scheme is not in effect, the fault association point is determined according to the logic relation among the faults, the base station is processed according to the fault solution corresponding to the fault association point, the indirect fault elimination is realized, and the reliability of fault solution is improved.

It should be noted that, when the step S105 is executed, that is, when the base station is subjected to fault processing according to the second fault processing scheme corresponding to the fault association point, if there are a plurality of fault association points, a plurality of corresponding second fault processing schemes may be determined, and the plurality of second fault processing schemes may be executed according to a certain priority order until the fault is resolved; alternatively, one of the plurality of fault associated points may be selected as a fault locating point to be processed, so as to perform fault processing on the base station according to the second fault processing scheme of the selected fault associated point to remove the fault, which will be described in detail below.

In an embodiment of the present application, the number of the fault associated points may be multiple, and in this case, the step S204, that is, determining the corresponding second fault handling scheme according to the fault associated points, may include: respectively acquiring attribute information corresponding to a plurality of fault association points; selecting a target fault associated point from the plurality of fault associated points according to the attribute information corresponding to the plurality of fault associated points; and generating a second fault processing scheme according to the target fault association point.

The attribute information may be information including an attribute of the fault association point, and may include information such as a category, time, and orientation. In the embodiment of the present application, one failure associated point selected from among the plurality of failure associated points is referred to as a target failure associated point.

Specifically, after a plurality of fault associated points are acquired, attribute information, such as category information, corresponding to each fault associated point is acquired, and then a plurality of attribute information is acquired, the attribute information meeting the requirements can be selected from the plurality of attribute information as target attribute information, the fault associated point corresponding to the target attribute information is the target fault associated point, and then a second fault handling scheme is generated according to the target associated point, wherein the target fault associated point meets the requirements, so that the second fault handling scheme generated according to the target fault associated point also meets the requirements to a certain extent.

The specific requirement to be met may be set by a user, or may be automatically set by the base station according to the working requirement, for example, the category may be closest to the category of the fault location point, the fault time may be closest to the fault time of the fault location point, or the position closest to the fault location point.

In order to improve the efficiency of generating the second failure handling plan, when the target failure-related point is selected from the plurality of failure-related points, the processing is performed according to a certain analog logic, instead of being performed out of order. The basic principle can be a fuzzy matching judgment algorithm based on the same subsystem, the related subsystem, the same kind of problems, the same kind of influence results (alarm similarity) and the like. The bottom platform subsystem of the whole system is an operation maintenance system and a drive bottom system, the Data transmission system is an FPGA (programmable logic array) and a PL (physical layer), the service system is a wireless Link layer (layer two) module L2 (including a MAC (Media Access Control), a PDCP (Packet Data Convergence Protocol), a Data Link layer of an RLC (Radio Link Control sublayer), an HL (High-Level communication Protocol, a higher layer Protocol module), the same category (attribute) is identified according to the same alarm source, similarity is found again in the category, at this time, an algorithm logic is needed, similar fields are synonymous, if different processing measures are available, and if the processing scheme is appropriate, the algorithm program automatically executes troubleshooting.

In an embodiment of the present application, selecting a target failure associated point from among a plurality of failure associated points according to attribute information corresponding to the plurality of failure associated points may include: respectively acquiring a plurality of fault codes corresponding to a plurality of fault association points; acquiring similarity information between fault codes of fault locating points and fault codes of a plurality of fault associated points respectively; and selecting a target fault associated point from the plurality of fault associated points according to the attribute information and the similarity information.

The similarity information may be understood as information including degrees of similarity between fault codes of fault locating points and fault codes of multiple fault associated points, and may also be referred to as matching degree information.

Specifically, a plurality of fault codes corresponding to the plurality of fault association points are respectively obtained, similarity information between the fault code of the fault locating point and the fault code of each fault association point is determined, so that a plurality of pieces of similarity information are obtained, and the target fault association point can be selected from the plurality of fault association points according to the attribute information and the similarity information.

Specifically, a plurality of failure associated points that belong to the same category or a more similar category as the category of the failure anchor point may be first selected from among the plurality of failure associated points based on the attribute information, for example, the category, and then a failure associated point having the highest similarity may be selected as the target failure associated point among the plurality of failure associated points according to the similarity information.

That is, a fault associated point with the highest similarity to the fault location given point may be selected from the multiple fault associated points as the target fault associated point, for example, referring to fig. 3 and table 1, when a fault occurs, for the same category of reasons, it is found after analysis that the fault including the field x1 is superior to the fault including the field x1 or x2 in similarity, and the fault including the field x1 and x3 is superior to the fault including the field y 1. Therefore, the fault association point corresponding to the fault (r) can be used as the target fault association point, and then the second fault processing scheme a corresponding to the fault (r) can be executed to eliminate the fault (r).

Further, in order to improve reliability of failure elimination and ensure that a failure can be completely eliminated, the second failure handling scheme corresponding to the multiple failure association points may be executed according to a priority order.

For example, referring to fig. 3 and table 1, when a fault (r) occurs, the fault (r) including the cause of the field x1 is analyzed to be better than the fault (r) including the field y1 and the fault (c) including the field x1 and x3 in similarity to the fault (r) including the field x1 or x 2. Therefore, the algorithm firstly considers the execution of the scheme A corresponding to the fault, secondly the scheme E corresponding to the fault and finally the scheme C corresponding to the fault is a standby execution scheme (can not be executed) according to similar priority when matching the logic. The higher the matching degree or similarity is, the higher the priority of execution is, and the lower the matching degree or similarity is, the lower the priority of execution is.

Therefore, when the number of the fault associated points is multiple, the target fault associated point is determined according to the attribute information and the similarity information of each fault associated point, and then the second fault processing scheme corresponding to the target fault associated point is determined, so that the reliability of fault processing is ensured.

It should be noted that, during the fault processing, the time of the fault processing may be considered, because during the user peak period, if the processing action is too large, network paralysis within a certain range may be caused, so during the user peak period (for example, 8 o 'clock-22 o' clock), if the action of power off of the whole network occurs in the processing measure, the algorithm may first determine whether all cells where the existing base station is located are faulty, and then may perform the processing on site; if only 1 cell is in fault and other cells are alive, the scheme processing of a single cell is preferentially carried out, under the condition that the processing scheme is invalid, a timer is started and a network manager is informed on line, and the whole station is restarted according to network disconnection when the non-busy time period is reached (if the network manager does not recognize the network disconnection, manual operation is switched back). The plan is to prevent the problem caused by excessive treatment from being serious and is used as an emergency measure for automatic control of the algorithm. Based on this, the present application proposes the following examples:

that is, in an embodiment of the present application, the method for processing a fault of a base station may further include: acquiring a cell to which a base station belongs; acquiring fault states and/or working states of other base stations in a cell; generating fault processing time of the base station according to fault states and/or working states of other base stations in the cell; and performing fault processing on the base station according to the fault processing time and the first fault processing scheme.

Specifically, after the first failure handling scheme is obtained, the cell to which the base station belongs may be obtained, and a failure state and/or a working state of another base station in the cell may be obtained, where the failure state may be a failure or non-failure survival state), and the working state may be in a working state or may be in a non-working state, that is, an idle state. Thereafter, a failure handling time of the base station may be generated based on the failure status of other base stations in the cell to determine whether to handle directly (i.e., execute the first failure handling scheme) in the field or to handle after waiting a period of time.

Specifically, if all other base stations are in a failure state, the first failure handling scheme may be immediately executed to resolve the failure of the base station; and if the base station in the fault state does not exist in other base stations, only the single-cell base station carries out fault processing according to the first fault processing scheme. This prevents the problem from becoming serious due to excessive handling.

It should be noted that, when determining the failure handling time of the base station, the failure handling time may be based not only on the failure states of other base stations in the cell, but also on the operating states of other base stations, and may also be based on any factor that may affect the failure handling time, such as the service time of the base station, the importance degree, and other factor characteristics.

In order to more clearly illustrate the method for processing the fault of the base station according to the embodiment of the present application, the following description is made in detail with reference to fig. 4 and 5:

the embodiment of the application establishes a base station fault alarm processing database which comprises alarm information, an alarm fault post-processing scheme set and a scheme execution script. Then, the database is used as a core to establish a fault processing flow as shown in fig. 4.

Due to different requirements of each place, algorithm switch (fault intelligent processing open pipe) control can be added to the processing flow:

when the control switch is closed, the database collects fault solutions corresponding to the faults from the data, if the data are various, the optimal solutions and the suboptimal solutions are selected to be provided for maintenance personnel, and then fault removal processing is carried out manually according to reference solutions provided by the database. If the experience of the maintenance personnel is rich or the area has certain particularity, other schemes can be selected by the maintenance personnel for processing; meanwhile, a new processing scheme is embodied in the processing work order, and is subsequently screened and evaluated by technical experts, and if the scheme is appropriate, the scheme is included in an alarm fault post-processing database.

The data in the database may be, for example: 1. the equipment type aspect is as follows: when an alarm that the error code of an optical port of a radio frequency unit is large occurs, the optical fiber is in a possible situation of being flashed, the root cause is that the interface of a base station and the radio frequency is in a problem, and the recommended measure is to reset the base station and the radio frequency; 2. and service class aspect: the alarm of memory pool exhaustion suddenly occurs, and the possible reason is that the process is repeatedly hung up, the occupied resource is not released or the user cannot be released, and at this time, the relevant processing measures are as follows, in the processing scheme 1: cell deactivation, processing scheme 2: restart processor, processing scheme 3: restart baseband resources, and so on. When the algorithm switch is turned on, the self-judgment is performed in the system under the control of the program, and the processing is performed according to the priority processing principle.

The determination of the association processing measure may be determined according to an association attribute, and the association attribute may be, for example, a fault code, a fault name, a fault type, a fault cause, a fault subsystem, or a fault processing scheme.

When the control switch is turned on, the self-processing of the fault is carried out by software control, and the method is suitable for areas with few base station maintenance monitoring personnel and mature network arrangement; on the premise of opening the switch, when a base station has a fault, the base station can firstly acquire a log file according to information in a database, then saves logs required by research and development positioning problems to a specified directory, meanwhile, software carries out processing priority sequencing according to the severity of the fault, then a processing optimal scheme corresponding to the fault is automatically found in the database, and then a program can execute a fault-clearing script in the corresponding database. After the execution is finished, polling the state of the base station at the moment, checking whether the corresponding fault is cleared, and if so, automatically generating a fault processing work order; and if the alarm still exists, other measures are continuously executed until the fault cannot be processed within 3 times within 6 hours, at the moment, a notice is generated, maintenance personnel are informed, and then other processing schemes are used.

In the embodiment of the present application, a deduction algorithm (analog analysis algorithm) is added based on a database, and fig. 5 is a specific flow of an internal deduction algorithm (analog analysis algorithm).

Examples are as follows, case 1: the processing scheme applicable to the base band processor of the base station when the base band processor fails due to long-time operation is to perform reloading and start, case 2: the method comprises the steps that a quit alarm occurs in a cell, the occurring reasons comprise clock faults, transmission link abnormity, baseband board card faults, uplink and downlink bearing link abnormity and the like, a processing scheme needs software to analyze layer by layer to search for root reasons, firstly, the cell is tried to be activated, when the cell cannot be activated, the reason of cell starting is checked, finally, the bearing link abnormity is found, a program triggers uplink or downlink reconstruction, when the link cannot be established, algorithm guide analysis or correlation with a baseband processor is found, the processing scheme of a correlation case 1 is generated by self, and reloading measures of the processor are carried out to complete processing. And simultaneously, the processing result is input into a system, branch tree calculation of the same type of faults (cell quit and base band abnormity) is carried out, and an abnormal branch processing plan is added, so that the risk that no processing scheme exists when a new comprehensive problem appears later is reduced. The system is an evolving system, and can automatically deal with emergency problems without human intervention. Compared with other industrialized means, the system is not limited by the existing solidification scheme any more, can more flexibly process emergency abnormal conditions, and has certain self-learning and deduction capabilities.

Specifically, the algorithm logic may be implemented according to the fault logic relationship diagram shown in fig. 4 and the fault correspondence relationship shown in table 1.

In summary, the fault processing method of the embodiment of the application takes the database as the basic calculation pool, and can effectively improve the timeliness of fault processing, reduce the investment of maintenance personnel and reduce the repeatability of research and development of positioning problems for different fault points by optimizing the use scheme. Meanwhile, the method has the ability of self-learning analogy, and can carry out correlation analogy under the condition that the problem cannot be solved by manpower measures to find a more appropriate similar processing scheme for maximum troubleshooting.
