CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on the Chinese patent application with the application number of 202110475948.2 and the filing date of April 29, 2021, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is incorporated herein by reference.

technical field

The present application relates to the technical field of optical communication, and in particular, to a method, apparatus, electronic device and readable medium for processing a signal loss alarm message.

Background technique

At present, the most popular optical access network technology at home and abroad is PON (Passive Optical NetWorks, passive optical network). In the entire PON system, there are multiple PON ports on the OLT (Optical Line Terminal, optical line terminal), and each ONU ( Optical Network Unit (optical network unit) is connected to the PON access system through the PON port of the OLT. Since each PON port will be connected to a large number of ONUs, the workload of manual management of fault work orders is huge, so most of the existing networks use the work order system for dispatching one.

When a LOSi (Loss Of Signal) alarm message is detected on two or more ONUs under a certain PON interface, the LOSi alarm message is reported to the work order system, and the work order system will automatically dispatch a fault work order. The OLT will report the DG alarm message only when it detects that the ONU signal is lost and receives the ONU's DyingGasp (power failure) message. However, there are a certain number of defective ONUs in the existing network. Due to various reasons (for example, the ONU power adapter is not Matching, or the mains is in an undervoltage state before the power outage, etc.) The DyingGasp message cannot be reported during a power outage. If the ONU cannot report the DyingGasp message, when the ONU is powered off, the OLT can only detect the loss of the ONU signal but does not know that the ONU is powered off. At this time, it will report the LOSi alarm message to the work order system. Therefore, when a power outage in a certain area causes a large number of ONUs to lose power in a centralized manner but no PON interface signal is lost, if there are multiple such defective ONUs in the power outage area, the OLT will display LOSi alarm messages of multiple ONUs, and the work order system will misassign the faulty worker. In a single situation, when this situation is more frequent, it will cause more waste of human resources.

An embodiment of the present application provides a method for processing a signal loss alarm message. As shown in FIG. 1 , the method for processing a signal loss alarm message includes the following steps:

Step 11: After the signal loss LOSi alarm message of the ONU corresponding to the PON interface is generated, record the generation time of the LOSi alarm message.

If the OLT detects that a certain ONU (for example, the i-th ONU) corresponding to a certain PON interface has lost a signal, it generates a LOSi alarm message of the PON interface. In the embodiment of the present application, i represents the identifier of the ONU corresponding to the PON interface. In this step, after the LOSi alarm message of the PON interface is generated, and the LOS escape function of the PON interface is enabled, the generation time of the LOSi alarm message is recorded. It should be noted that the LOS escape function is set for each PON interface of the OLT, and the escape function of each PON interface can be manually enabled or disabled.

Step 12, in the case that the generation time of the LOSi alarm message falls within the currently opened escape time window, escape the LOSi alarm message as the first DGi alarm message.

The escaping described in the embodiment of the present application refers to generating the first DGi alarm message according to the LOSi alarm message. It should be noted that the LOSi alarm message is still retained, but the LOSi alarm message is no longer reported, but the generated first DGi alarm message is reported.

The escape time window refers to the time period in which the escape operation can be performed, and is limited by the start time and the end time. The escape time window is the time period between the start time and the end time. Within the duration of the preset first threshold X, when the number m of second DGi alarm messages in the DGi alarm record of the PON interface reaches the preset second threshold N, the escape time window is opened. The first threshold X is less than the opening duration of the escape time window, that is, the start time of the escape time window is before the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface, and the end time of the escape time window is between After the generation time of the current second DGi alarm message in the DGi alarm record of the PON interface. When the end time is reached, the escape time window closes. It should be noted that the time when the escape time window is judged to be opened is usually after the start time of the escape time window. When it is determined that the escape time window is open, it is traced back to the start time of the escape time window, and the escape time window is turned on. defined time window.

The first second DGi alarm message is the first second DGi alarm message among the m second DGi alarm messages in the DGi alarm record. The second DGi alarm message is a DGi alarm message generated after the PON interface receives the power-down message sent by the i-th ONU. That is to say, when the OLT detects that a certain ONU (for example, the i-th ONU) corresponding to a certain PON interface is lost, and the PON interface receives the DyingGasp message sent by the i-th ONU, it generates the first signal of the PON interface. Two DGi alarm messages.

In this step, once it is found that the generation time of the LOSi alarm message falls within the currently opened escape time window, the LOSi alarm message is escaped into the first DGi alarm message. The first DGi alarm message and the second DGi alarm message are both DGi alarm messages, but the first DGi alarm message is a DGi alarm message generated by escaping, and the second DGi alarm message is a DGi alarm generated based on the DyingGasp message sent by the ONU information.

Step 13, reporting the first DGi alarm message.

In this step, the first DGi alarm message is reported to the work order system, and the work order system is a functional module of the work order system and the network management device. It should be noted that, after the second DGi alarm message is generated, it is also reported to the work order system.

If the OLT generates the second DGi alarm message multiple times within the duration of the first threshold X, indicating that the ONUs in a certain area may be powered off, then, within the escape time window, if other ONUs ( The faulty ONU) has been powered off and cannot send the DyingGasp message to the OLT. The OLT only detects that the ONU signal is lost, and the resulting LOSi alarm message (but in fact the faulty ONU has been powered off at this time) may be a false alarm. This part of the LOSi alarm message is escaped into the first DGi alarm message and reported to the work order system, so as to avoid the mis-assignment of a faulty work order and improve the accuracy of ONU power failure judgment.

In the method for processing a signal loss alarm message provided by the embodiment of the present application, after the signal loss LOSi alarm message of the ONU corresponding to the PON interface is generated, the generation time of the LOSi alarm message is recorded; when the generation time of the LOSi alarm message falls within the currently enabled escape In the case of a time window, the LOSi alarm message is escaped as the first DGi alarm message, and the first DGi alarm message is reported, wherein the second DGi alarm record in the DGi alarm record of the PON interface within the preset first threshold X duration. When the number m of alarm messages reaches the preset second threshold N, the escape time window is opened, and the start time of the escape time window is before the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface. The end time of the time window is after the generation time of the current second DGi alarm message in the DGi alarm record of the PON interface. In the case of centralized power failure in an area, it can avoid the mis-assignment of fault work orders caused by reporting LOSi alarm messages when a defective ONU is powered down, and improve the accuracy of ONU power failure judgment.

In some embodiments, after recording the generation time of the LOSi alarm message, the method for processing a signal loss alarm message further includes the following steps: buffering the LOSi alarm message in a buffer; when the escape time window changes, or a preset When the scan period arrives, scan the buffer for LOSi alarm messages.

The change of the escape time window includes one or any combination of the following: the end time of the escape time window changes, and both the start time and the end time of the escape time window change.

In some embodiments, after recording the generation time of the LOSi alarm message (ie step 11), the method for processing a loss of signal alarm message may further include the following step: when the generation time of the LOSi alarm message does not fall within the currently enabled escape time window, and when the generation duration of the LOSi alarm message is greater than p times the first threshold X, the LOSi alarm message is reported, where p is an integer greater than 1. That is to say, the LOSi alarm messages that are not within the escape time window and the generated duration is longer than pX are time-out LOSi alarm messages, and report these time-out LOSi alarm messages to the work order system. Report the current time, not the generation time of the LOSi alarm message. In some embodiments, p may be 2.

In order to prevent the escaped alarm from remaining, the embodiment of the present application also needs to perform alarm recovery. Correspondingly, in some embodiments, after escaping the LOSi alarm message into the first DGi alarm message (ie, step 12), the method further includes the following steps: in response to receiving the LOSi recovery message, clearing the LOSi alarm message and the first DGi alarm message. A DGi alarm message, and the LOSi alarm recovery message and the first DGi alarm recovery message are reported.

In the embodiment of the present application, a DGi alarm record is maintained for each PON interface, and the DGi alarm record is used to record the second DGi alarm message and its information (including the generation time). In the DGi alarm record, each second DGi alarm message Arranged in positive order by generation time.

In some embodiments, the start time of the escape time window is T _N -X', and the end time of the escape time window is T _star +X', where X'=X+(T _N +T _star )/X, _TN is the generation time of the last second DGi alarm message in the DGi alarm record of the PON interface, and T _star is the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface.

In the embodiment of the present application, the escape time window includes two types: the first type is a fixed escape time window, the second type is a sliding escape time window, and the fixed escape time window refers to the start of the escape time window. Neither the time nor the end time changes, and the fixed escape time window closes once the end time is reached. The sliding escape time window means that the end time of the escape time window can be changed, for example, the end time can be adjusted backward, that is, the duration of the sliding escape time window is increased.

For different types of escape time windows, the opening conditions and the update process of DGi alarm records are different. The following describes the processing processes under the fixed escape time window and the sliding escape time window respectively.

The type of the escape time window is pre-configured. When the type of the escape time window is the first type (that is, the fixed escape time window), in some embodiments, as shown in FIG. 2 , the method for processing a signal loss alarm message The following steps can also be included:

Step 21, after generating the second DGi alarm message of the ONU corresponding to the PON interface, in response to the current escape time window not being opened, and the generation time Tn of the second DGi alarm message is the first in the DGi alarm record of the PON interface. The difference between the generation times T _star of the second DGi alarm message is less than or equal to the first threshold X, the number m of the second DGi alarm messages in the DGi alarm record of the PON interface is increased by 1, and the second DGi alarm message and its generation The time Tn is written into the DGi alarm record of the PON interface.

n is the number of the second DGi alarm message. In this step, once the second DGi alarm message is generated, the judgment of whether to update the escape time window and whether to update the DGi alarm record is triggered. When no escape time window is currently enabled, if the difference between the generation time Tn of the current second DGi alarm message and the generation time T _star of the first second DGi alarm message in the DGi alarm record is less than or equal to the first threshold X , indicating that the interval between the current second DGi alarm message and the first second DGi alarm message in the DGi alarm record is small, and frequent power failure alarms have occurred in the current period of time, so it is necessary to record the second DGi alarm message and the frequent The number of power failure alarms that occur (ie m), then add 1 to the number m of the second DGi alarm message in the DGi alarm record of the PON interface, and write the second DGi alarm message and its generation time Tn into the PON DGi alarm record of the interface.

Step 22, in response to m being equal to the second threshold N, according to the generation time T _star of the first second DGi alarm message and the generation time Tn of the second DGi alarm message, calculate the start time and end time of the escape time window, And open the escape time window.

In this step, if m=N, it means that within the duration X, at least N second DGi alarms are generated, and it can be considered that the ONU in the area corresponding to the PON interface is powered off, for example, the power adapter of the ONU does not match or Before the power failure, the utility power is in an undervoltage state, etc. In this case, determine and open the escape time window, so as to escape the LOSi alarm messages that fall within the escape time window, so as to avoid false alarms to the work order system .

In some embodiments, after generating the second DGi alarm message of the ONU corresponding to the PON interface, the method for processing the signal loss alarm message may further include the following steps: If the difference between the generation time Tn of the alarm message and the generation time T _star of the first and second DGi alarm messages in the DGi alarm record of the PON interface is greater than the first threshold X, the DGi alarm record of the PON interface is cleared. That is to say, when no escape time window is currently enabled, if the difference between the generation time Tn of the current second DGi alarm message and the generation time T _star of the first second DGi alarm message in the DGi alarm record is greater than the first Threshold X, indicating that the interval between the second DGi alarm message and the first second DGi alarm message in the DGi alarm record is relatively large, and no frequent power failure alarms have occurred in the current period of time, so it is not necessary to record the second DGi alarm message The alarm message and the number of frequently occurring power failure alarms, the DGi alarm record of the PON interface is cleared, so as to re-judge when the next second DGi alarm message is generated.

In some embodiments, the method for processing a signal loss alarm message may further include the following steps: after generating the second DGi alarm message of the ONU corresponding to the PON interface, in response to the currently opened escape time window, no longer update the The DGi alarm record of the PON interface, that is, the current second DGi alarm message and its generation time Tn are no longer written into the DGi alarm record of the PON interface. That is to say, when the second DGi alarm message is generated, once the escape time window is opened, the LOSi alarm message can be monitored according to the escape time window, and it is meaningless to record the current second DGi alarm message, so it is no longer updated. DGi alarm records of the PON interface, thereby saving storage resources and reducing data processing.

In some embodiments, the method for processing a signal loss alarm message may further include the following steps: in response to the arrival of the end time of the escape time window, closing the escape time window, and clearing the DGi alarm record of the PON interface.

In order to clearly illustrate the solution of the embodiment of the present application, the following describes the update process of the fixed escape time window in detail by using a specific example with reference to FIG. 3 and FIG. 4 . It should be noted that FIG. 3 is an update flow of a fixed escape time window when the escape time window is not opened. As shown in Figure 3, the update process of the fixed escape time window includes the following steps:

Step 301: Generate a second DGi alarm message of the ONU corresponding to the PON interface.

Step 302, it is judged whether there is a second DGi alarm message in the DGi alarm record of the PON interface, if so, step 304 is performed; otherwise, step 303 is performed.

In this step, if there is a second DGi alarm message in the DGi alarm record of the PON interface, it is further judged whether there is currently an escape time window open (ie, step 304 is executed); if there is no second DGi alarm message in the DGi alarm record of the PON interface If there is a second DGi alarm message, the second DGi alarm message generated in step 301 (that is, the current second DGi alarm message) and the generation time of the second DGi alarm message are written into the DGi alarm record of the PON interface (that is, step 303 is executed. ).

Step 303: Write the current second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface.

Since there is no second DGi alarm message in the DGi alarm record of the current PON interface, after the second DGi alarm message generated in step 301 and its generation time Tn are written into the DGi alarm record of the PON interface, Tn is the The generation time of the first and second DGi alarm messages in the DGi alarm record, so T _star =Tn.

In step 304, it is determined whether there is currently an open escape time window, and if so, step 305 is performed; otherwise, step 306 is performed.

Step 305, the DGi alarm record of the PON interface is no longer updated.

The second DGi alarm message generated during the opening of the escape time window is no longer written into the DGi alarm record.

Step 306: Determine whether the difference between the generation time Tn of the current second DGi alarm message and the generation time T _star of the first second DGi alarm message in the DGi alarm record of the PON interface is less than or equal to the first threshold X, and if so, execute the step 308, otherwise, step 307 is executed.

Step 307: Clear the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface.

In this step, if Tn-T _star >X, it means that the opening condition of the escape time window is not satisfied, then clear the first and second DGi alarm messages and their generation time in the DGi alarm record of the PON interface.

Step 308: Add 1 to the number m of the second DGi alarm message in the DGi alarm record of the PON interface, and write the second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface.

In this step, if Tn-T _star ≤ X, it means that the first opening condition of the escape time window is satisfied, then update the DGi alarm record of the PON interface (including the number m of second DGi alarm messages and the second DGi alarm message ), and further determine whether the second opening condition of the escape time window is satisfied (ie, step 309 is executed).

Step 309 , determine whether the number m of second DGi alarm messages in the DGi alarm record of the PON interface is equal to the second threshold N, and if it is equal, perform step 310 , otherwise, end the process.

In this step, if m=N, it means that the second opening condition of the escape time window is satisfied. At this time, if both conditions for opening the escape time window are satisfied, then the escape time window is opened (ie, step 310 is executed) ;If m≠N, that is, m<N, it means that the second opening condition of the escape time window is not met, and the escape time window is not opened. The second DGi alarm message generated this time triggers this fixed escape time window. The update process is over (without opening the escape time window).

Step 310: Calculate the start time and end time of the escape time window according to the generation time T _star of the first second DGi alarm message and the generation time Tn of the current second DGi alarm message, and open the escape time window.

Step 311, when the end time of the escape time window arrives, close the escape time window, and clear the DGi alarm record of the PON interface.

With reference to Figure 4, if the current generation time of the second DGi alarm message is Tn, the generation time T _star of the first second DGi alarm message in the DGi alarm record of the PON interface is T1, and the current second DGi alarm message is The last second DGi alarm message in the DGi alarm record of the PON interface, when the two conditions for opening the escape time window are met, the start time of the escape time window is calculated as T _N -X', and the escape time The end time of the window is T _star +X', where X'=X+(T _N +T _star )/X.

When the type of the escape time window is the second type (that is, the sliding escape time window), in some embodiments, as shown in FIG. 5 , the method for processing a signal loss alarm message may further include the following steps:

Step 51, after generating the second DGi alarm message of the ONU corresponding to the PON interface, in response to the currently opened escape time window, and the generation time Tn of the second DGi alarm message and the DGi alarm record of the PON interface No. ( The difference between the generation times T _(n-N+1) of n-N+1) second DGi alarm messages is less than or equal to the first threshold X, and the second DGi alarm message and its generation time Tn are written into the PON The DGi alarm of the interface is recorded, and the (n-N+1)th second DGi alarm message is determined to be the first second DGi alarm message.

In this step, once the second DGi alarm message is generated, the judgment of whether to update the escape time window and whether to update the DGi alarm record is triggered. Under the circumstance that the escape time window is currently enabled, if the generation time Tn of the current second DGi alarm message is the same as the generation time T ₍ n-N+1)th second DGi alarm message in the DGi alarm record The difference between _N+1) is less than or equal to the first threshold X, indicating that the interval between the second DGi alarm message and the (n-N+1)th second DGi alarm message in the DGi alarm record is small, so the current The second DGi alarm message and its generation time Tn are written into the DGi alarm record of the PON interface. Delete the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface, so as to adjust T _star to T _(n-N+1) .

Step 52: Adjust the end time of the escape time window according to the generation time of the updated first second DGi alarm message and the generation time Tn of the second DGi alarm message.

In this step, since T _star has been adjusted to T _(n-N+1) in step 51, and the generation time Tn of the second DGi alarm message has been written into the DGi alarm record, in this step, According to the updated T _star and the current generation time Tn of the second DGi alarm message, adjust the end time of the escape time window to T _(n-N+1) +X', which is the end time of the escape time window Adjust backward to realize sliding adjustment of escape time window.

In some embodiments, the method for processing a signal loss alarm message further includes the following steps: in response to the arrival of the end time of the escape time window, closing the escape time window, and deleting the first second in the DGi alarm record of the PON interface DGi alarm messages and their generation time, so as to keep the latest (N-1) second DGi alarm messages in the DGi alarm record of the PON interface, so that it can be judged whether the occurrence of each second DGi alarm message generated subsequently can be determined Power down phenomenon, the escape time window determined by this is more accurate.

In some embodiments, the method for processing a signal loss alarm message may further include the following steps: after generating the DGi alarm message of the ONU corresponding to the PON interface, in response to the currently open escape time window, and the DGi alarm of the PON interface If the record is empty, write the current second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface, taking the generation time Tn of the current second DGi alarm message as the first second DGi alarm record in the DGi alarm record of the PON interface. The generation time T _star of the DGi alarm message.

In some embodiments, the method for processing a signal loss alarm message may further include the following steps: Step 61, after generating the second DGi alarm message of the ONU corresponding to the PON interface, in response to the current no-open escape time window, and The difference between the generation time Tn of the second DGi alarm message and the generation time T _star of the first second DGi alarm message in the DGi alarm record of the PON interface is less than or equal to the first threshold X, and the second DGi alarm record of the PON interface is set as the second DGi alarm message. The number m of DGi alarm messages is increased by 1, and the second DGi alarm message and its generation time Tn are written into the DGi alarm record of the PON interface; step 62, in response to m being equal to the second threshold N, according to the first second DGi alarm message The generation time T _star of the alarm message and the generation time Tn of the current second DGi alarm message are calculated, the start time and end time of the escape time window are calculated, and the escape time window is opened. That is to say, when the type of the escape time window is the second type, and the escape time window is not enabled when the second DGi alarm message is generated, the update process of the escape time window (ie, steps 61-62) The process of updating the escape time window of the first type (ie, steps 21-22) is the same, and details are not described here.

In order to clearly illustrate the solution of the embodiment of the present application, the update process of the sliding escape time window will be described in detail below with reference to FIG. 6 a , FIG. 6 b and FIG. 7 , through a specific example. As shown in Figure 6a, the update process of the sliding escape time window includes the following steps:

Step 601: Generate a second DGi alarm message of the ONU corresponding to the PON interface.

Step 602, it is judged whether there is currently an open escape time window, if so, step 603 is performed; otherwise, step 606 is performed.

Step 603: Determine whether the difference between the generation time Tn of the second DGi alarm message and the generation time T _(n-N+1) of the (n-N+1)th second DGi alarm message in the DGi alarm record of the PON interface is less than or equal to the first threshold X, if yes, go to step 604, otherwise, end the process.

Step 604, write the second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface, adjust T _star to T _(n-N+1) , and according to the updated first second DGi alarm message The generation time and the generation time Tn of the second DGi alarm message are used to adjust the end time of the escape time window.

n is the number of the second DGi alarm message. In this step, delete the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface, so as to adjust T _star to T _(n-N+1) , and to escape the end of the time window The time is adjusted to T _(n-N+1) +X'.

With reference to FIG. 7 , the generation time of the current second DGi alarm message is Tn, and it is determined that the escape time window A is opened after the second DGi alarm message is generated. At this time, Tn=T _N , the escape time window A The start time of is T _N -X', and the end time of the escape time window A is T ₁ +X', where X'=X+(T _N +T ₁ )/X. If Tn-T _(n-N+1) ≤ X, write the current second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface, and delete the first DGi alarm record of the PON interface. The second DGi alarm message and its generation time, so that T _star is adjusted from T1 to T _(n-N+1) , and correspondingly, the end time of the escape time window A is adjusted to T _star +X' (that is, T _{( n-N+1)} +X'), so as to obtain the escape time window A', that is, the escape time window A' is opened, and the start time of the escape time window A' remains unchanged, which is still T _N -X', that is The escape time window A' is extended backward relative to the escape time window A.

Step 605, when the end time of the escape time window arrives, close the escape time window, and delete the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface, so that it can be recorded in the DGi alarm record of the PON interface. The most recent (N-1) second DGi alarm messages are retained.

Steps 601-605 are the update process of the sliding escape time window when the current escape time window is opened. The following describes the process of opening the sliding escape time window when the current escape time window is not opened with reference to FIG. 6b. As shown in Figure 6b, the process includes the following steps:

Step 606, it is judged whether the DGi alarm record of the PON interface is empty, if so, go to step 608, otherwise, go to step 607.

Step 607: Write the current second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface.

Since there is no second DGi alarm message in the DGi alarm record of the current PON interface, after the second DGi alarm message generated in step 601 and its generation time Tn are written into the DGi alarm record of the PON interface, Tn is the The first and second DGi alarm messages in the DGi alarm record, at this time, T _star =Tn.

Step 608: Determine whether the difference between the generation time Tn of the current second DGi alarm message and the generation time T _star of the first second DGi alarm message in the DGi alarm record of the PON interface is less than or equal to the first threshold X, and if so, execute Step 610, otherwise, go to step 609.

Step 609: Clear the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface.

Step 610: Add 1 to the number m of second DGi alarm messages in the DGi alarm record of the PON interface, and write the current second DGi alarm message and its generation time Tn into the DGi alarm record of the PON interface.

In this step, if Tn-T _star ≤ X, it means that the first opening condition of the escape time window is satisfied, then update the DGi alarm record of the PON interface (including updating the number m of second DGi alarm messages and the second DGi alarm message), and further determine whether the second opening condition of the escape time window is satisfied (ie, step 611 is executed).

Step 611, whether the number m of the second DGi alarm messages in the DGi alarm record of the PON interface is equal to the second threshold N, if it is equal, go to step 612, otherwise, end the process.

In this step, if m=N, it means that the second opening condition of the escape time window is satisfied. At this time, if both conditions for opening the escape time window are satisfied, then the escape time window is opened (ie, step 612 is executed) ;If m≠N, that is, m<N, it means that the second opening condition of the escape time window is not met, the escape time window is not opened, and the current second DGi alarm message triggers the update of the sliding escape time window. Process ends.

Step 612, according to the generation time T _star of the first second DGi alarm message and the generation time Tn of the current second DGi alarm message, calculate the start time and end time of the escape time window, open the escape time window, and execute step 605 .

It should be noted that after opening the escape time window, it is necessary to monitor the opening time of the escape time window. When the end time T _(n-N+1) +X' of the escape time window arrives, close the escape time window, and delete the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface, so as to retain the latest (N-1) second DGi alarm messages in the DGi alarm record of the PON interface.

In order to clearly illustrate the solution of the embodiment of the present application, in the following with reference to FIG. 8 and FIG. 9 , an example of a fixed escape time window and an instance of a sliding escape time window are taken as examples to process the signal loss alarm message in the embodiment of the present application. The process is explained in detail.

FIG. 8 is an example of a fixed escape time window. As shown in FIG. 8 , user configuration: X is 3 seconds, N is 5, and p=2. The OLT generates second DGi alarm messages at 3 seconds, 3.2 seconds, 4.2 seconds, 4.5 seconds, 5.3 seconds, 5.6 seconds, and 7.2 seconds, respectively, and the DGi numbers n of the second DGi alarm messages are 1-7 respectively. If there is no initial escape time window, the first second DGi alarm message is generated in 3 seconds, and T _star is recorded in the DGi alarm record as T1=3. When the second to fifth second DGi alarm messages are generated subsequently, Record T2=3.2, T3=4.2, T4=4.5, T5=5.3 respectively. The difference between the generation time of these several second DGi alarm messages and T _star is less than the user-defined first threshold X = 3 seconds, and when the fifth second DGi alarm message DGi5 is generated, the number n of second DGi alarm messages The user-defined second threshold N=5 has been reached, and the condition for opening the escape time window is satisfied. The start time of the calculated escape time window is T5-X', the end time of the escape time window is T1+X', X'=3+(T5-T1)/3=3.76, therefore, the escape time window is 1.54 seconds to 6.76 seconds. At this time, the escape time window is opened, and all LOSi alarm messages stored in the buffer are scanned. LOSi 1 and LOSi2 whose LOSi alarm message generation time is between 1.54 seconds and 6.76 seconds are escaped as the first DGi alarm message. DGi6 is not recorded in the DGi alarm record because it is ignored within the escape time window. DGi7 is generated after the escape time window has closed and, therefore, is recorded in the DGi alert log. The LOSi3 generated outside the escape time window cannot be escaped as the first DGi alarm message. If the LOSi3 is stored in the buffer for 6 seconds, it will be reported according to the LOSi alarm disappearance timeout.

Fig. 9 is an example of sliding escape time window, as shown in Fig. 9, user configuration: X is 3 seconds, N is 5. The OLT generates a second DGi alarm at 3 seconds, 3.2 seconds, 4.2 seconds, 4.5 seconds, 5.3 seconds, 5.6 seconds, and 7.2 seconds, respectively, and the DGi numbers n of the second DGi alarm messages are 1-7 respectively. If there is no initial escape time window, the first second DGi alarm message is generated in 3 seconds, and T _star is recorded in the DGi alarm record as T1=3. When the second to fifth second DGi alarm messages are generated subsequently, Record T2=3.2, T3=4.2, T4=4.5, T5=5.3 respectively. Same as the fixed escape window open judgment process, open escape time window 1, scan all LOSi alarm messages stored in the buffer, and escape LOSi1 and LOSi2 as the first DGi alarm message. When the sixth second DGi alarm message DGi6 is generated, since it is detected that the escape time window 1 has been opened, it is judged whether the difference between T6 and T2 is ≤ the first threshold X (X=3) configured by the user, and it is found that T6(5.6s)-T2(3.2s)=2.4s is less than 3 seconds, therefore, write the sixth second DGi alarm message and its generation time T6 into the DGi alarm record, and adjust T _start to T2. Adjust the end time of the currently opened escape time window 1 to T2+(3+(T6-T2)/3)=7 seconds. At this time, the escape time window 1 becomes the escape time window 1', and the escape time window 1' is still on. All LOSi alarm messages stored in the scanning buffer are scanned, and there is no new escapeable LOSi alarm within the escape time window 1'. When the end time (7s) of the escape time window 1' arrives, close the escape time window 1', update the DGi alarm record again at this time, and keep the latest 4 second DGi alarm messages, that is, delete the DGi2 corresponding to T2, DGi3, DGi4, DGi5, and DGi6 are retained in the DGi alarm record, and T _start = T3 at this time. When the seventh second DGi alarm message DGi7 is generated, since the escape time window 1' is closed at this time, DGi3, DGi4, DGi5, and DGi6 are retained in the DGi alarm record, and T _start is T3 at this time, so compare T3 and T7, it is found that T7(7.2s)-T3(4.2s)=3, which is not greater than the first threshold of 3 seconds, so a new escape time window 2 is opened, and the start time of escape time window 2 is T7-(3+ (T7-T3)/3)=3.2 seconds, and the end time is T3(4.2s)+(3+(T7(7.2s)-T3(4.2s))/3)=8.2 seconds. All LOSi alarm messages stored in the buffer are scanned, and LOSi3 and LOSi4 are escaped as the first DGi alarm message.

In the embodiment of the present application, a DGi alarm record is maintained for each PON interface, and the DGi alarm record is used to record the most recent m times (m is less than or equal to N) second DGi alarm messages generated by the PON interface and their generation times. The generation time of m second DGi alarm messages determines a time window (ie, escape time window), which is used as a criterion for intelligently determining whether the ONU is powered off. The generation of the second DGi alarm message and the open state of the current escape time window trigger the update of the DGi alarm record. The maintenance of the DGi alarm record can adopt two strategies of fixed time window and sliding time window.

In the implementation of this application, the LOS escape function can be set to be turned on or off, and the time period parameters before and after LOSi escape (ie the first threshold X) and the criterion for judging the frequency of DGi alarms in this time period (ie the second threshold N) can also be Adjust according to the actual situation to improve the accuracy of OMU power failure judgment. The solution of the embodiment of the present application is flexible, and the LOS escape function switch and related parameters can be configured according to the needs of different users. When the LOS escape function is enabled, it can be accurately judged whether the defective ONU is powered off, so as to avoid the situation of misassigning the fault work order.
