Network element exception handling method and network management system

Technical Field

Networking architecture of X2 interface links, for example, referring to fig. 1, a schematic diagram of a networking architecture of an X2 interface link in an LTE system in the prior art is shown, as shown in fig. 1: in an LTE network, base station network elements are connected by an X2 interface link. Each base station network element reports the state of the base station network element and the alarm information of the X2 interface link between the base stations to a unified OMC (Operation and Maintenance Center) network management system through a network management interface of each base station network element.

If one base station (such as ENB0) fails, due to the failure of the base station, the alarm cannot be reported to the upper-level OMC network management system, and other base stations (ENB 1-ENBn) connected with the base station respectively report alarm information of 'X2 interface link failure' to the OMC network management system, so that a large amount of alarm information can be generated on the OMC network management system. For the maintenance personnel, the real faulty network element device does not report the alarm information, and the non-faulty network element device can report a large amount of alarm information, so that the alarm information is redundant and is not beneficial to positioning the faulty network element device.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

In a mobile communication network, network elements exchange system information through transmission links. In order to ensure the reliability of the link transmission information between the network elements, the source side network element sends link detection information to the target side network element connected by the transmission link at regular time, and once the response information of the opposite end network element is not received within the specified time, the link between the source side network element and the target side network element is considered to have a fault, and the source side network element reports 'link fault alarm' information to the superior network management system.

When a network element device fails (such as power failure), all network element devices connected with the network element device generate link failure alarm information due to the fact that response information of the network element device cannot be detected, and the link failure alarm information is respectively reported to the unified OMC network management system, a large amount of link failure alarm information reported by the network element can be received on the unified OMC network management system, redundant alarm information is more, the failed network element device cannot report an alarm to the network management system due to failure, the alarm information reported by normal network element devices connected with the failed network element device can only be received on the side of the OMC network management system, and the problem of a large amount of alarms caused by the failure of one network element device connected with the failed network element device cannot be correctly positioned.

The idea of the embodiment of the invention is as follows: an alarm rule merging module is preset at the OMC network management system side, information with the same network element identification and the same abnormal reason of the network element in the link fault alarm information reported by the multi-network element equipment is merged according to the alarm rule merging module, so that the same link fault alarm information is eliminated, the report of redundant alarm information is reduced in real time, and the network element with the real fault can be positioned according to the network element identification information in the link fault alarm information, so that maintenance personnel can maintain the network element equipment conveniently.

Example one

step 201: acquiring link abnormity warning information reported by a plurality of network elements; the link abnormity warning information comprises identification information of an abnormal network element and a reason of the abnormal network element.

In the embodiment of the present invention, the network management system refers to a system for performing management and maintenance on each network element (i.e., base station), such as an OMC network management system.

The link anomaly warning information refers to anomaly warning information reported by all network elements connected to a certain network element when the certain network element fails (such as power failure), for example, as shown in fig. 1, the network element includes ENB0, ENB1, ENB2, …, and ENB n, the ENB1 to the ENB n are all connected to ENB0, and when the ENB0 fails, the ENB1 to the ENB n report the link anomaly warning information to the network management system.

In a specific implementation, the abnormal cause may include a failure of an X2 interface link, a failure of an S1 interface link, and the like, and specifically, may be determined according to an actual situation, which is not limited by the embodiment of the present invention.

The identification information of the connected network elements is pre-stored in the two connected network elements, and the reason for the abnormality of the connected network elements can be detected according to the data transmission process when the data transmission process has a fault.

Each network element under the management of the network management system is preset with conditions that when the network element is abnormal, the identification information of the abnormal network element and the abnormal reason are added into the link abnormity warning information, and further when the link abnormity warning information is reported to the network management system, the identification information of the abnormal network element and the abnormal reason of the abnormal network element can be added into the link abnormity warning information.

The identification information of the abnormal network element refers to a network element identification of the abnormal network element, each network element has a unique identification, and different network elements have different identification information, for example, a network element includes a network element a, a network element B and a network element C, the identification information of the network element a is identification 1, the identification information of the network element B is identification 2, and the identification information of the network element C is identification 3.

The identification information of the network element may be a digital identification, such as identification 1, identification 2, identification 3, etc., or may be a capital letter identification, such as identification a, identification B, identification C, etc., or may be a lower case letter identification, such as identification a, identification B, identification C, etc.

It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present invention, and are not to be taken as the only limitation of the embodiments of the present invention.

The network management system may receive the link abnormality warning information reported by the multiple network elements managed by the network management system, and execute step 202 after receiving the link abnormality warning information.

Step 202: and calling a preset merging rule template, and merging the abnormal alarm information of each link according to the identification information and the abnormal reason of each network element.

For example, referring to fig. 4, a schematic diagram of a multi-network element alarm merging rule provided in an embodiment of the present invention is shown, where the provided merging rule template is rule 1, and the monitoring time in the merging rule template may be set in advance to be 1-600 s, that is, from a certain time, merging processing is performed on the link abnormal alarm information monitored in 600s or 500s, and the specific monitoring time may be set in advance by a maintenance person. The merging rule template is also provided with a start time and an end time, that is, the network management system will perform merging on the link abnormal alarm information within the start time and the end time, and the link abnormal alarm information outside the time is not considered, for example, the start time is: 11 days 2 and 10:00 in 2019, and the end time is as follows: and 12 days-9: 00 in 2 and 11 months in 2019, namely, the link abnormity warning information received by the network management system is combined from 10 am in 11 days in 2 and 11 months in 19 years to 9 am in the next day. The merging rule template is also preset with an abnormal reason item, that is, link abnormal alarm information of different abnormal reasons is merged, for example, link abnormal alarm information whose abnormal reasons are all X2 interface link failures is merged, link abnormal alarm information whose abnormal reason is S1 interface link failures is merged, and the like.

Of course, in a specific implementation, one or more merging rule templates may be preset, and specifically, a developer may determine according to an actual situation, which is not limited in this embodiment of the present invention.

Of course, in the merge rule template, enabling and disabling options, and creating, deleting, applying buttons and the like (as shown in fig. 4) may also be preset, and the enabling option may be used to enable the merge rule template selected by the maintenance personnel; the disallow option may be used to disallow use of a merge rule template selected by the maintenance person; the creation button can be used for popping up a corresponding creation popup window when a maintainer clicks the button, and the maintainer fills a corresponding merging rule according to the creation popup window to generate a new merging rule template; the delete button may be used to delete a selected merge rule template when a maintainer selects the merge rule template and clicks the delete button; the application button may be used to click the button to apply a certain merge rule template to merge the link abnormal alarm information after the maintenance personnel selects the certain merge rule template.

Of course, a close button (as shown in the lower right corner of fig. 4) may also be provided, and when a maintenance person clicks the close button, the multi-network element merge rule display interface may be closed, and after a certain merge rule template is enabled, the multi-network element merge rule display interface may be closed, or after any merge rule template is stopped from being used, the multi-network element merge rule display interface may be closed.

When the link abnormal alarm information reported by multiple network elements is merged, a preset merging rule template can be called, and the link abnormal alarm information is merged according to each identification information and each network element abnormal reason, that is, the identification information is the same, and the link abnormal alarm information with the same network element abnormal reason is merged, for example, the link abnormal alarm information comprises information 1, information 2, information 3, information 4 and information 5, the identification information of the network element corresponding to the information 1 is a, and the abnormal reason is x; the identification information of the network element corresponding to the information 2 is a, and the abnormal reason is y; the identification information of the network element corresponding to the information 3 is a, the abnormal reason is x, the identification information of the network element corresponding to the information 4 is b, and the abnormal reason is x; the identification information of the network element corresponding to the information 5 is a, and the anomaly reason is x, it can be known that the identification information and the anomaly reason of the abnormal network element corresponding to the information 1, the information 3 and the information 5 are the same, and then the information 1, the information 3 and the information 5 can be merged, that is, the information is merged to obtain a link anomaly alarm information, so as to reduce the number of the same link anomaly alarm information in the network management system and eliminate redundant data.

After the preset merge rule template is called, the identification information and the network element abnormality cause in the link abnormality warning information may be respectively judged with the identification merge condition and the network element abnormality merge condition to determine whether the two satisfy the merge condition, and specifically, detailed description will be given below in the preferred embodiment.

In a preferred embodiment of the present invention, the step 202 may include:

sub-step P1: and calling the merging rule template, and sequentially judging whether the identification information meets the identification merging conditions and whether the network element abnormal reasons meet the network element abnormal merging conditions aiming at the identification information and the network element abnormal reasons.

In the embodiment of the present invention, the merge rule template may include an identification merge condition and a network element exception merge condition.

The identifier merging condition refers to an identifier merging condition determined according to identifier information in the link abnormality alarm information reported by the network element in advance, for example, when the plurality of link abnormality alarm information reported by the network element a includes the identifier 1, the identifier 2, and the identifier 3, the identifier merging condition is that when the subsequently received link abnormality alarm information includes the identifier 1, the identifier 2, or the identifier 3, that is, the subsequently received link abnormality alarm information satisfies the identifier merging condition.

The network element abnormal merging condition refers to a network element abnormal merging condition determined according to a network element abnormal reason in the link abnormal alarm information reported by the network element in advance, for example, when a plurality of pieces of link abnormal alarm information reported by the network element B include reason 1, reason 2 and reason 3, the network element abnormal merging condition is that when the subsequently received link abnormal alarm information includes reason 1, reason 2 or reason 3, that is, the subsequently received link abnormal alarm information satisfies the network element abnormal merging condition.

After receiving the link abnormality warning information reported by the subsequent network element, the merge rule template may be called, and for each identification information and each network element abnormality reason, whether the identification information meets the identification merge condition and whether the network element abnormality reason meets the network element abnormality merge condition are sequentially determined, and substep P2 is executed.

Sub-step P2: and merging the link abnormal alarm information according to the identification information and the network element abnormal reason under the condition that the identification information meets the identification merging condition and the network element abnormal reason meets the network element abnormal merging condition.

And merging the link abnormity warning information into one repeated link abnormity warning information according to the identification information and the network element abnormity reason under the condition that the identification information meets the identification merging condition and the network element abnormity reason meets the network element abnormity merging condition.

Specifically, the following four cases can be classified:

1. link abnormity warning information with the same reason as the next identification information and the next network element abnormity does not exist;

2. the link abnormal alarm information which is the same as the next identification information and is different from the abnormal reason of the next network element exists;

3. the link abnormal alarm information which has the same reason as the next network element abnormal and is different from the next identification information exists;

4. and the link abnormity warning information has the same reason as the next network element abnormity and the same identification information as the next identification information.

In case 4, step K3 is executed.

Step K3: and if so, deleting the next link abnormal alarm information.

And deleting the next link abnormal alarm information when the next link abnormal alarm information which is the same as the link abnormal alarm information acquired in advance in the network management system exists.

And the judgment process is respectively carried out aiming at the acquired at least one next link abnormal alarm information, and the same next link abnormal alarm information is deleted, thereby reducing the redundancy of the link abnormal alarm information stored in the network management system.

In the process, the same link abnormity warning information is merged, so that the redundancy of the link abnormity warning information stored in the network management system can be reduced, and great convenience is brought to maintenance personnel for positioning the abnormal network element.

The method for processing the network element exception, provided by the embodiment of the invention, comprises the steps of acquiring link exception alarm information reported by a plurality of network elements, calling a preset merging rule template according to the link exception alarm information including identification information and network element exception reasons of the abnormal network elements, merging the link exception alarm information according to the identification information and the network element exception reasons, acquiring at least one merged link exception alarm information according to a merging processing result, and storing the merged link exception alarm information in a network management system.
