Description

MANAGEMENT SYSTEM AND METHOD FOR RESCHEDULING ERROR CONDUCTING DEADLINE}

TECHNICAL FIELD The present invention relates to a network system, and more particularly, to a maintenance system and method for adjusting a processing time limit of a plurality of errors generated in at least one managed device.

The mobile communication system provides a communication service to a mobile station based on a network. Each device of the mobile communication system, such as a base station, a base station controller, and a switch, is provided with a plurality of software for performing unique functions. For example, in the case of an exchange, software for performing call control, billing, and various call processing related statistical calculation functions may be installed.

Each device of the mobile communication system requests error processing by transmitting error occurrence information to a maintenance system through a network when a software error occurs. The maintenance system writes error handling software for handling the error, and transmits the error handling software to the device that requested the error handling to handle the error.

The conventional maintenance system sets an error processing deadline by reflecting only the generated software error class. As a result, it does not meet the requirements of each device or customer.

According to one embodiment of the present invention, there is provided a maintenance system and method for adjusting the processing time of a plurality of errors occurring in at least one management target device to reflect the characteristics of each device or the needs of customers.

According to an embodiment of the present disclosure, a maintenance system for processing a software error installed in at least one managed device through a network may include: a communication unit configured to receive a plurality of error occurrence information from at least one managed device for a predetermined period of time; The storage unit stores the class and class processing deadlines for each type, determines the class and processing period of the generated error, and adjusts the processing period of the generated error by reflecting preset limitation information in the processing period for each class of the generated error. It includes a control unit.

According to the following embodiment, the maintenance system may adjust the error processing period by reflecting the characteristics of each device or the customer's request for a plurality of errors occurring in at least one management target device.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the following description, when there is a risk of unnecessarily obscuring the gist of the present invention, a detailed description of well-known functions and configurations is omitted.

The management target device transmits the error occurrence information to the maintenance system through the network. Referring to FIG. 1, according to an embodiment, the management target device 10 may include at least one of a base station 11, a base station controller 12, and a mobile switch 13 of a mobile communication system.

According to an embodiment, the maintenance system 20 receives a plurality of error occurrence information from at least one management target device 10 for a predetermined period of time. The error occurrence information includes the type of error. The maintenance system 20 determines the class and the processing period of the generated error based on the received error occurrence information and the pre-stored class by class of error type and processing period by class.

In addition, the maintenance system 20 adjusts the processing period for each grade by reflecting the preset limitation information in the processing period for each grade of the generated error, and transmits the processing time to the adjusted management target device 10. The limit information includes an error class according to the type of error, a processing cost for each class, an error processing schedule due to the error occurrence information receiving date, and an error processing limit cost within the schedule. In addition, the restriction information further includes processing cost constraints according to the relationship between the processing costs of each grade, the adjusted error processing deadlines and the error processing limitation costs, the processing deadline constraint based on the processing deadline of each grade, and the processing deadline constraint of each grade.

Errors occurring in each device of the mobile communication system are classified into a plurality of classes according to the types of errors. For example, referring to Table 1 below, the error grade includes 'Critical', 'Major', and 'Minor'.

Error class Error type Critical Errors that seriously affect service capacity, traffic, billing, and maintainability, requiring immediate corrective action Major Errors affecting system startup, maintenance, and management, which are reviewed by communication service providers and require action in consultation with software developers. Minor Simple errors that do not affect system functions and services

1 and 2, the communication unit 21 of the maintenance system 20 communicates with each device of the mobile communication system.

The storage unit 22 includes error type classification, type error class, processing period by class, processing cost by class, error processing schedule deadline, error processing limiting cost within time limit, processing cost limiting condition, processing time limiting condition, and processing time limiting condition by class. Stored. In addition, the storage 22 may further store the satisfaction for each error class.

The control unit 23 receives a plurality of error occurrence information from at least one device in the mobile communication system through the communication unit 21 (S1).

The controller 23 determines the class of the generated error based on the error occurrence information and the error class information for each error type stored in advance (S2).

The control unit 23 determines the type of the error, the error class for each type, the processing period for each class, and the error processing cost for each class based on the error type classification stored in the storage unit 22 (S3).

Referring to Table 2 below, the predetermined processing deadlines for each grade are constants 'X ₁ ', 'X ₂ ', 'X ₃ '. For example, the treatment deadlines for each grade are immediate, four and twelve weeks, respectively.

Error class Critical Major Minor Error handling cost a b c Error handling deadline X ₁ X ₃ X ₃ Adjustment error handling deadline Y ₁ Y ₂ Y ₃ Error Handling Limited Cost K Error handling schedule P

The control unit 23 adjusts the processing period for each grade by reflecting the restriction information in the determined processing period for each grade (S4). That is, the control unit 23 reflects the error processing limit cost, the error processing schedule time limit, the processing cost limit condition, the processing time limit condition, and the processing time limit condition for each grade, which are stored in the storage unit 22 in a predetermined processing time period for each grade. The deadline for each grade is adjusted.

In detail, the control unit 23 determines a processing cost for each grade, an error processing limit cost, and an error processing schedule. Referring to Table 2, the processing costs for each class are constants 'a', 'b', and 'c', and the error processing limit cost is 'K', and the error processing time limit is 'P'. Then, the controller 23 sets the processing time limit for each grade that satisfies the processing cost limit condition and the processing time limit condition as variables. Referring to Table 2, the adjustment error handling deadlines for each class are variables 'Y ₁ ', 'Y ₂ ', and 'Y ₃ '.

The control unit 23 applies the adjustment error processing deadline variable for each grade to the processing cost constraint, the processing term constraint, and the processing term constraint for each grade.

Treatment cost constraints are expressed by equations of the processing cost and adjustment error deadline variables for each class and the processing cost for each class (Equation 1). More specifically, the equation for multiplying the processing cost by class and the corresponding adjustment error handling time limit variables (Y _{1 ,} Y _{2 ,} Y ₃ ) for each class, and adding the multiplication result for each class should be less than or equal to the error processing limit cost (K). do.

aY ₁ + bY ₂ + cY ₃ <K

For example, when the processing costs for each grade are 160,000 won, 100,000 won, and 30,000 won, and the error processing cost is 800,000 won, Equation 1 becomes '16Y ₁ + 10Y ₂ + 3Y ₃ <= 80'.

On the other hand, the processing deadline constraint is expressed by the adjustment processing deadline variables (Y _{1 ,} Y _{2 ,} Y ₃ ) for each grade and the equation of the deadline of error processing (Equation 2). In other words, the sum of the adjustment error processing time variables for each class is equal to the error processing time limit (P).

Y ₁ + Y ₂ + Y ₃ = P

For example, when the error processing schedule is 10 weeks (= P), the sum of the adjustment process deadlines variable for each grade is 'Y ₁ + Y ₂ + Y ₃ = 10' according to Equation (2).

On the other hand, the processing deadline constraint for each grade is expressed by the equation (Equation 3) that the processing deadline is less than the constant 'S'.

Yi <S (i = 1, 2, 3)

For example, when the error handling time limit Y ₁ of the critical grade is limited to less than three weeks, according to the class error handling time limitation condition, Equation 3 becomes 'Y ₁ <3'.

If you apply 'Y ₁ = 2' that meets the error handling constraint 'Y ₁ <3' to the processing cost constraint (Equation 2),

Processing Cost Constraints' 16Y ₁ + 10Y ₂ + 3Y ₃ <= 80 'becomes '32 + 10Y ₂ + 3Y ₃ <= 80', and the following equation 4 is established.

10Y ₂ + 3Y ₃ <= 48

Referring to FIG. 3, in the two-dimensional graph in which the adjustment error handling time variable Y ₂ of the error class 'Major' is the horizontal axis, and the adjustment error handling time Y ₃ of the error class 'Minor' is the vertical axis, the equation of Equation 4 is shown. Can be represented by the conditional line / CD.

In addition, based on the critical processing condition 'Y ₁ = 2' and the processing time constraint of Equation 2, 'Y ₁ + Y ₂ + Y ₃ = 10' of Equation 2 is 'Y ₂ '. + Y ₃ = 8 ', referring to FIG. 4, the equation of Equation 2 may be represented by a reference line / AB.

That is, as the size of the critical grade is adjusted according to the constraint of the critical grade, the adjustment error processing period of the remaining error grades Major and Minor is determined. When the adjustment error handler variable 'Y ₁ = 2', each of the adjustment error handler variables (Y ₂ and Y ₃ ) of the remaining error classes at the point where the reference line / AB intersects the condition line / CD ('O') The optimum values '3.43' and '4.57' can be obtained. Therefore, the adjustment error processing deadlines Y ₁ , Y ₂ , and Y ₃ for each of the error classes are 2 weeks, 3.43 weeks, and 4.57 weeks.

In this way, the predetermined processing deadlines for each grade (immediately, 4 weeks, 12 weeks) are adjusted to 2 weeks, 3.43 weeks, and 4.57 weeks.

The control unit 23 transmits the adjustment error processing period for each grade to an operator computer (not shown) that manages at least one device that has transmitted error occurrence information through the communication unit 31.

On the other hand, according to one embodiment, the control unit 23 can obtain the communication service provider satisfaction by using the rating adjustment processing period and the rating satisfaction set in advance in the storage unit 22 as described above.

The controller 23 sets the satisfaction function F using the adjustment period for each grade as shown in Equation 5 below. Satisfaction rate of each error class is constant f _{1 ,} f _{2 ,} f ₃ In this case, the satisfaction function (F) multiplies the satisfaction level (f _{1 ,} f _{2 ,} f ₃ ) by the error class and the adjustment error processing time variables (Y ₁ , Y ₂ , Y ₃ ), respectively, and adds the multiplication result by each class. One function. That is, the satisfaction function (F) is a function that reflects the satisfaction of the telecommunication service provider by grade.

F = f ₁ Y ₁ + f ₂ Y ₂ + f ₃ Y ₃

For example, if the communication service provider satisfaction for the adjustment error processing time variables Y ₁ , Y ₂ , Y ₃ for each grade is 10 points, 5 points, and 2 points, respectively, the communication service provider satisfaction function F is given by Equation 5. It can be expressed as 'F = 10xY ₁ + 5xY ₂ + 2xY ₃ '.

According to the above description, if the values of the adjusted error processing deadlines (2, 3.43, 4.57) for each grade are substituted into the communication service provider satisfaction function (F) of Equation 5, the communication service provider satisfaction is' F = 10x2 + 5x3. 43 + 2x4.57, giving us 46.29 points.

As described above, according to the present embodiment, the maintenance system may adjust the optimal error processing period by reflecting the restriction information in the preset error processing period for each error level occurring in the management target device for a certain period of time. In addition, by adjusting the processing time for each grade to the optimum error processing time, by processing the error within the adjusted processing time can increase the satisfaction of the communication service provider.
