Description

Method for Determinating Target Time to Perform Function-specific in TMN Agent}

The present invention relates to a network management system, and more particularly, to a method for flexibly determining a management target time when implementing a function related to performance management in a TMN agent which is an internal component of a TMN.

Generally, a network management system is a system that controls a complex network in order to maximize network efficiency and productivity.

Network management has different meanings depending on the communication network applied. In other words, the public-switched telecommunication network refers to real-time network monitoring and control for optimizing network performance, and the packet-switched data network collects necessary management information from network configuration equipment to provide network Means proper operation and maintenance.

The network management system has been constructed and used distributed management system for each network, but in recent years in accordance with the expansion of the function of the network management system and the advance of the backbone (backbone), the application of the TMN has been expanded.

TMN collects information for network management by connecting operating systems, communication facilities, and work stations into a single network to collectively manage complex and advanced telecommunication networks from a unified perspective. Perform storage, delivery, and administrative control.

TMN is an internal component, and is provided with various agents that are connected to each management object and perform network management functions.

These TMN agents perform various functions necessary for network performance management on a periodic basis. These functions include fault management, network utilization statistics, and network configuration equipment management.

However, in order for the TMN agent to periodically perform various functions related to network performance management, it is important to determine the management target time.

However, conventionally, only a fixed granularity period (hereinafter, abbreviated as GP) and periodic synchronization time (hereinafter, abbreviated as PST) have been considered in determining this management target time. Moreover, PST was rarely considered.

As a result, the TMN agent performed a specific function at a fixed time according to a certain time flow, and thus the flexibility in performing various functions related to network performance management was significantly reduced.

The object of the present invention was devised in view of the above, and when a TMN agent performs a specific function, a method of flexibly determining the management target time in consideration of all GP, PST, and current time is provided. To provide.

A characteristic of the method for determining a management target time for performing a function of a TMN agent according to the present invention for achieving the above object is the step of determining the time interval from the current time to the initial management target time in seconds, and Setting the SIT and the NTT, determining whether the GP and the PST are changed after the time interval is determined, and setting a periodic alarm according to the checking result, and whenever the set periodic alarm ends, the GP And periodically checking whether the PST has been changed and increasing the set SIT and NTT according to the checking result.

Preferably, the time interval up to the first management target time is determined to be less than or equal to the GP, and as the time interval up to the first management target time is determined, the first alarm is considered in consideration of variables GP and PST based on the current time. alarm is set to one-time.

After the setting of the SIT and the NTT, it is checked whether the GP and the PST are changed. If the GP or the PST is changed, the changed GP and PST values are set and then the initial management target time is reached. The time interval is determined again, and the periodic alarm is set when the GP or the PST has not changed.

In addition, after the periodic alarm setting step, periodically check whether the GP and the PST are changed, and when the GP or the PST is changed, set the changed GP and PST values and then time interval until the initial management target time. Re-determine and increase the set SIT and NTT when the GP or PST has not changed.

Finally, when setting and increasing the SIT and NTT, the GP has one of the following types: day, hour, minute, and second, and according to each type The SIT and NTT values are determined by calculating time and PST.

Hereinafter, a preferred embodiment of a method for determining a management target time for performing a function of a TMN agent according to the present invention will be described with reference to the accompanying drawings.

In the present invention, when the TMN agent performs a specific function, the flexible management target time is determined in consideration of GP, PST, and current time (hereinafter, abbreviated as CT). That is, whenever the TMN agent performs a specific function, the GP and PST are checked, and when the GP or PST is changed as a result of the inspection, the target time is set again.

In particular, in the present invention, the flexible management target time is set when the GP and PST change, and thus the scan initiation time (hereinafter abbreviated as SIT) and the next management when implementing a function related to performance management in the TMN agent The next target time (hereinafter abbreviated as NTT) is also determined flexibly.

1 is a flowchart illustrating a procedure for determining a management target time for performing a function of a TMN agent according to the present invention.

Referring to FIG. 1, first, an initial time interval (first interval) should be determined, which is a time interval up to the first management target time based on CT to obtain a time interval in seconds (S1).

After that, the SIT and NTT are set according to the result of obtaining the time interval from the initial management target time (S2).

In this case, the variables GP, PST, and CT should be taken into account so that the initial alarm is set to one-shot, and the time interval until the initial management target time should be less than or equal to the GP. GP is the period of the management target time.

After the first one-time alarm is finished, check whether the GP and PST change (S3). At this time, if the GP or PST is changed, set the changed GP and PST values (S4), and then calculate the time interval from the CT to the initial management target time in seconds. On the other hand, if GP or PST has not changed, a periodic alarm is set (S5).

Next, after each periodical alarm, check whether the GP and PST have been changed periodically (S6). If the GP or PST has changed, set the changed GP and PST values (S4), and then again, based on CT The time interval up to the initial management target time is obtained in seconds. However, if GP or PST has not changed, SIT and NTT are increased (S7).

2 is a flowchart illustrating a procedure of determining the SIT and NTT according to the present invention, wherein the SIT and NTT are determined by calculating CT and PST according to the type of GP.

FIG. 2A is a flowchart for determining SIT and NTT when the GP type is day. First, the second unit value (hereinafter, abbreviated as Csec) of the CT (current time) and the PST (synchronous time) are determined. The second unit value (hereinafter, abbreviated as Ssec) is calculated by considering an hour (S20). Then, the relationship between the Csec and the Ssec is checked by comparing the magnitudes of these two values (S21).

In this case, if Ssec is larger than Csec, the return time (referred to as Rsec) is calculated through Equation 1 below (S22), and SIT and NTT are calculated by Equation 2 below. Determine (S25).

Rsec = Ssec-Csec + $ day * DAY_SEC

In Equation 1, "$ day" is a day unit variable of GP, and "DAY_SEC" is a value calculated in seconds per day.

SIT = CT,

NTT = SIT + GP

However, in the check result, if Csec is greater than Ssec, Rsec is obtained through Equation 3 below (S23), and SIT and NTT are determined according to Equation 2 above (S25).

Rsec = DAY_SEC + Ssec-Csec + $ (day-1) * DAY_SEC

When Csec and Ssec are the same, Rsec is obtained through the following Equation 4 (S24), and SIT and NTT are determined by Equation 2 (S25).

Rsec = $ day * DAY_SEC

Figure 2b) is a flow chart for determining the SIT and NTT when the GP type is hour (hour), first calculates the Csec and Ssec to the minute (S30). Then, the relationship between Csec and Ssec is checked by comparing the magnitudes of these two values (S31).

In this case, if the Ssec is larger than the Csec, the Rsec is obtained through the following Equation 5 (S32), and the SIT and NTT are determined by the above Equation 2 (S35).

Rsec = Ssec-Csec + $ hour * HOUR_SEC

In the above Equation 5, "$ hour" is a time unit variable of GP, and "HOUR_SEC" is a value calculated for one hour in seconds.

However, in the check result, if Csec is greater than Ssec, Rsec is obtained through Equation 6 (S33), and SIT and NTT are determined by Equation 2 (S35).

Rsec = DAY_SEC + Ssec-Csec + $ (hour-1) * HOUR_SEC

When Csec and Ssec are the same, Rsec is obtained through Equation 7 (S34), and SIT and NTT are determined by Equation 2 (S35).

Rsec = $ hour * HOUR_SEC

FIG. 2C is a flowchart for determining SIT and NTT when the GP type is minutes. First, Csec and Ssec are calculated in consideration of Ssec (S40). Then, the relationship between the Csec and the Ssec is checked by comparing the magnitudes of these two values (S41).

In this case, if the Ssec is larger than the Csec, the Rsec is obtained through Equation 8 (S42), and the SIT and NTT are determined by the above Equation 2 (S45).

Rsec = Ssec-Csec + $ min * MIN_SEC

In Equation 8, "$ min" is a minute unit variable of GP, and "MIN_SEC" is a value in which one minute is calculated in seconds.

However, in the check result, if Csec is larger than Ssec, Rsec is obtained through Equation 9 (S43), and SIT and NTT are determined by Equation 2 (S45).

Rsec = HOUR_SEC + Ssec-Csec + $ (min-1) * MIN_SEC

When Csec and Ssec are the same, Rsec is obtained through Equation 10 (S44), and SIT and NTT are determined by Equation 2 (S45).

Rsec = $ min * MIN_SEC

2D) is a flowchart for determining SIT and NTT when the GP type is second. First, Csec and Ssec are calculated (S50). Where Ssec is equal to the GP calculated in seconds. Then, the relationship between the Csec and the Ssec is checked by comparing the magnitudes of these two values (S51).

In this case, if Ssec is greater than Csec, Rsec is obtained through Equation 11 (S52), and SIT and NTT are determined by Equation 2 (S55).

Rsec = Ssec-Csec

However, in the check result, if Csec is larger than Ssec, Rsec is obtained through Equation 12 (S53), and SIT and NTT are determined by Equation 2 (S55).

Rsec = MIN_SEC + Ssec-Csec + $ sec

In Equation 12, "$ sec" is a second unit variable of GP.

When Csec and Ssec are the same, Rsec is obtained through Equation 13 (S54), and SIT and NTT are determined by Equation 2 (S55).

Rsec = MIN_SEC

According to the present invention, when the TMN agent performs a number of functions related to network performance management, GP, PST, and CT can be considered in consideration of flexible management target time, and TMN agent can determine specific functions for network performance management. In doing so, they can flexibly respond to changes in GP and PST.

It also makes it easier to implement all relevant functions for network performance management in the TMN, and allows the user to flexibly adjust the functions performed by the TMN agent over time. In particular, users can flexibly manage network performance by simply adjusting GP and PST.
