It can treat and process the warning data of different version separately and exactly and ensure to be backward compatible. The theory of the present invention is that the warning data collected from the network units is transformed by adding a mapping table between the identifications of the network units warning and the network warning in the collection units which receives the warning from the network units, the network warning corresponding to the network units warning is transmitted to the network management system and is processed by the network management system according to the network warning.

Description

The present invention relates to the field of communications, and in particular, to a technology for uniformly managing multiple network element devices of different versions of the same type in a centralized network management system.

Background technique

Network management refers to the comprehensive management of various hardware and software facilities that make up the network to achieve the purpose of making full use of these resources, while ensuring that the network provides reliable communication services to users. Its essence is to monitor, control and coordinate various network resources, and report and process it in time when the network fails, especially to alert the administrator to maintain it as soon as possible.

According to the International Standardization Organization (International Standardization Organization)

The definition of "ISO", network management has the following five functions: fault management, billing management, configuration management, performance management, and security management.

Among them, fault management is the most basic function of network management, which refers to the management operation in the case of abnormal system. Simply put, it is to find the location of the fault and recover. The goal is to automatically monitor, log, and notify users of network failures so that the network operates efficiently; billing management is responsible for recording network resource usage and the cost of using those resources; configuration management is the definition, collection, monitoring, and management of system configuration parameters. To optimize network performance; performance management is mainly to collect and collect statistics, such as network throughput, user response time, and line utilization, in order to evaluate system performance such as network resource health and communication efficiency, and analyze each Trends in communication operations between systems, or balancing the load between systems; security management refers to controlling access to network resources in accordance with local guidelines to ensure that the network is not compromised and that important information is not compromised by unauthorized users. access.

At present, in network management, the application of centralized network management technology has become more common. This technology can centrally manage all network elements in the communication system, and provide basic maintenance basic functions such as configuration management, performance management, fault management, and security management, as well as auxiliary network management such as network optimization, performance report formulation, and alarm correlation analysis. Features. The specific process is that the collection unit sends the alarm data from each network element to the centralized network management system, and the system performs corresponding processing according to the data. However, there are still some problems with the above techniques. For example, when different versions of NE devices exist in the system, alarm data of different versions of NE devices cannot be managed at the same time.

For example, when a network element has two versions with inconsistent alarm data, for example, the alarm record R is an event alarm in version 1.0, a failure alarm is changed in version 1.1, and the version 1.1 is used in the processing of the alarm. The "event alert" in the above version 1.0 becomes a "fault alert". Because the corresponding recovery alert cannot be received, these fault alerts cannot be recovered and become "dead alarms".

Similarly, if the alarm record T is an emergency alarm in version 1.0 and a general alarm in version 1.1, if the version 1.1 is used, the above "emergency alarm" becomes "general alarm", and the version 1 is not correctly represented. The urgency of the alarm.

Therefore, in the actual application, the above solution has the following problems: The alarm data of different NE devices cannot be managed at the same time.

Summary of the invention

In view of the above, the main purpose of the present invention is to provide a centralized network management system alarm processing method and a network management system, which can simultaneously unify multiple network element devices of the same type and different versions in the same centralized network management system. Access management enables different versions of alarm data to be treated separately and processed correctly to ensure backward compatibility.

To achieve the above objective, the present invention provides a centralized network management system alarm processing method, including:

The first mapping table is configured to include a mapping relationship between the network element alarm item and the network alarm item. When the alarm information from the network element is received, the first mapping table is queried according to the network element alarm item identifier in the alarm information. And replacing the identifier of the network element alarm item in the alarm information with the corresponding network alarm item identifier that is queried, and sending the alarm information to the centralized network management device.

The first mapping table of the corresponding version is set for the network element having different versions.

The method also includes the following steps:

The centralized network management device searches for the alarm name, alarm level, and alarm type of the alarm in the network alarm item data table according to the network alarm item identifier in the received alarm information, and processes the alarm according to the query result.

The first mapping table includes at least a network element alarm item identifier field and a network alarm item identifier field. The first night shot table may further include an alarm name field, an alarm level field, and an alarm type field.

The present invention further provides a centralized network management system, which includes a plurality of network elements and a centralized network management device, and the system further includes:

At least one collecting unit, the first mapping table is further disposed in the collecting unit; the first mapping table is configured to store a mapping relationship between the network element alarm item and the network alarm item;

The collecting unit is configured to receive the alarm information from the network element, query the first mapping table according to the identifier of the network element alarm item in the alarm information, and replace the alarm in the alarm with the corresponding network alarm item identifier that is queried. The network element alarm item is identified, and the alarm information is sent to the centralized network management device.

The at least two versions of the plurality of network elements, in the collecting unit, set the first mapping table of the corresponding version to the network elements of different versions.

The first mapping table includes at least a network element alarm item identifier field and a network alarm item identifier field. The first mapping table may further include an alarm name field, an alarm level field, and an alarm type field.

The centralized network management device further includes:

A network alarm item data table, configured to save an alarm identifier, an alarm name, an alarm level, and an alarm type of the network alarm item;

The centralized network management device is further configured to query the alarm name, alarm level, and alarm type of the alarm according to the network alarm item identifier in the received alarm, and process the alarm according to the query result.

By comparison, it can be found that the technical solution of the present invention is different from the prior art in that, in the prior art, the problem that the alarm data of different versions of the network element device cannot be simultaneously managed is collected by the device for receiving the alarm from the network element device. A network element alarm identifier and a network alarm identifier mapping table are added to the unit, and after the ID mapping of the network element alarm item data collected from the network element is performed, the network alarm corresponding to the network element alarm is sent to the network management system.

The difference in this technical solution brings more obvious beneficial effects, so that the centralized network management system can fully and effectively achieve backward compatibility with different versions of the same type of network element device, ensuring that the centralized network management system can Smooth, simple, and compatible upgrades. BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a schematic structural diagram of a network management system according to an embodiment of the present invention; FIG. 2 is a flow chart showing a method for processing an alarm of a centralized network management system according to an embodiment of the present invention.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings.

In general, the principle of the present invention is: by setting a mapping table including a mapping relationship between a network element alarm item and a network alarm item in the collection unit, and receiving a network element alarm from a different version of the network element device in the collection unit. Then, the corresponding network alarm item is detected according to the mapping table, and sent to the centralized network management system, so that different versions of the alarm data can be separately treated and correctly processed to ensure backward compatibility.

In order to make the invention easier to understand, first, the concepts of original alarm, network alarm, and alarm mapping are explained.

The original alarm is the alarm on the NE side. The corresponding alarm number, alarm level, and alarm type are called the original alarm ID, the original alarm level, and the original alarm type.

A network alarm is an alarm on the centralized network management system. The corresponding alarm number, alarm level, and alarm type are called network alarm ID, network alarm level, and network alarm type.

The alarm mapping is performed by mapping the original alarm ID, the original alarm level, and the original alarm type of each NE version to a network alarm ID, network alarm level, and network alarm type. 'Alarm mapping is actually an operation of alarm data redundancy. It maps the original alarm recordsets of different versions, and finally obtains a set of network alarm recordsets. This set of network alarm records can accommodate different versions. Original alarm record set.

The following mapping relationships (algorithms) are given in tabular form and are described in detail.

First, describe the data mapping of the NE version 1.0. The alarm items of the NE version 1.0 are as follows: Table 1: The original version of the original alarm of the NE version 1.0 alarm data table Alarm ID Name Alarm Level Alarm Type

1 Temperature alarm Emergency

2 Humidity alarm Important Fault

3 communication alarm general failure

It can be seen that Table 1 contains "original alarm ID,", "original alarm name,", "original alarm level," and "original alarm type", etc. Among them, Table 1 will correspond to each "original alarm ID". The "original alarm level" and "original alarm type" for the "temperature alarm", "humidity alarm" and "communication alarm" for the NE side alarms of the T, "2", and "3" are listed.

The network element side alarm item data mapping table 2 and the network side alarm item data mapping table 3 at the time of version 1.0 are shown in the following Table 1: Table 2: Network element side alarm item data mapping table when the network element version is 1.0

Table 3: Network Side Alarm Item Data Mapping Table for Version 1.0

It should be noted that, in Table 2, the network alarms corresponding to "Network Alarm ID" of "1001", "1002", "1003" or "Network Element Alarm ID" are T, "2", "3" respectively. The data of the "network alarm level" and "network alarm type" whose names are "temperature alarm", "humidity alarm" and "communication alarm" are respectively listed. And in Table 3, according to the number in Table 1 above The data related to "Network Alarm ID", "Network Alarm Name,,""Network Alarm Level," and "Network Alarm Type" are listed separately.

After the network element of version 1.0 is connected to the centralized network management system, a data of the above table 2 is retained in the data collection unit, and a table 3 data is retained on the centralized network management system side. When the data collection unit collects the alarm ID of the network element of the version 1.0 network element as alarm number 1, it converts the network alarm ID to "1001" according to the mapping relationship of Table 3 and reports it to the centralized network management system. The network management system knows what the alarm is based on the data mapping of Table 4. Similarly, the acquisition unit is the same for other alarm data processing, and the description of the article will not be repeated here. It should be noted that the collection unit described herein is a module between the network elements of the network element, and is responsible for collecting data of the network element device.

Below we will describe in detail the data mapping of the NE version 1.1. Table 4 shows the contents of the NE version 1.1 alarm item data. Table 4: NE version 1.1 Alarm item data table

It should be noted that, corresponding to the content of the network element version 1.0 alarm item data table in Table 1, we can see from Table 4 that the "primary alarm ID" of the version 1.1 alarm item is "1". The "original alarm level" is "important", which is inconsistent with the situation in version 1.0 above. In addition, the "raw alarm ID" in Table 4 is "original alarm ID" corresponding to "moisture alarm". The alarm type is "Event", which is different from the above version 1.0. The other aspects are exactly the same as those in version 1.0.

Therefore, according to the data content of the network element version 1.1 alarm item in Table 4, we can obtain the data mapping relationship of the network element side alarm item data in the version 1.1 shown in Table 5 below, and the network side alarm item data in the version 1.1 shown in Table 6. Mapping relations. Table 5: Network element side alarm item data mapping table in version 1.1 Network network report network network alarm ID alarm alarm name alarm level

ID

2001 1 A- Important Events

Storm

2002 2 Humidity is important Event

1003 3 Communication General Failure Table 6: Network side alarm item data table when NE version 1.1

It should be noted that, in Table 5, the content corresponding to the previous Table 4, wherein "network alarm name", "network alarm ID" for "temperature alarm" is "2001", and its "network alarm level," is "important" " The network alarm type" corresponding to the "humidity alarm" of "2002" is "event,". It should be noted that the above two points are the same as the previous version 1.0. The information related to the alarm data mapping is not completely consistent. The network side alarm item data of the network element version 1.1 in Table 6 is exactly the same as the corresponding content in Table 5.

According to the above, the centralized network management system can store the network alarm data table as shown in Table 7 below. Table 7: Network Alarm Item Data Table Network Network Report Network Notice Network Alarm

Alarm ID Alarm Name Police Level Type

1001 temperature emergency 2001 Temperature reports important events

1002 Humidity is important

2002, ¹ soil

1003 Communication General Failures It should be noted that, in conjunction with the relevant data of the previous version 1.0 and version 1.1, it can be seen from Table 7 that the network alarm item data stored in the centralized network management system in Table 7 is actually version 1.1 and version. 1.0 corresponds to a union of data content.

After the network element of version 1.1 is connected to the centralized network management system (this time, the network management system may continue to manage the network elements of version 1.0), and the data collection layer of the network element 1.1 retains a table 5 data. The network management system side maintains a copy of the data in Table 7.

The mapping table and the network alarm item data table and the like according to the present invention have been described above. The structure of the network management system according to an embodiment of the present invention will be described below with reference to FIG.

As shown in FIG. 1 , the centralized network management system of the present invention includes a 1.0 version network element 10, a 1.1 version network element 20, and a first collection unit 11 supporting a version 1.0 network element, and a network element supporting a 1.1 version. Two acquisition units 21, and a centralized network management system 30.

The first collection unit 11 supporting the network element of the 1.0 version stores the version 1.0 network element alarm item and the network alarm item mapping table, that is, the network element side alarm item data mapping table 2 and version 1.0 when the network element version is 1.0. Time network side alarm item data mapping table Table 3. The first collecting unit 11 is configured to: after collecting the alarm of the 1.0 version network element 10, determine the network alarm ID corresponding to the network element alarm ID according to the 1.0 version network element 10 alarm item and the network alarm item mapping table, and The network alarm ID is reported to the centralized network management system 30. The second collection unit that supports the 1.1 version of the network element stores the 1.1 version of the network element 20 alarm item and the network alarm item mapping table, that is, the network element side alarm when the version is 1.1. Network side alarm item data table 6 in the data mapping table table 5 and the network element version 1.1. The second collecting unit 21 is configured to determine a network alarm ID corresponding to the network element alarm ID according to the 1.1 item network element 20 alarm item and the network alarm item mapping table after collecting the 1.1 version network element 20 alarm, and the network The alarm ID is reported to the centralized network management system 30. The centralized network management system 30 in the network management system shown in FIG. 1 stores a network alarm item data table in which the contents of the network alarm item data table of the above table 7 are stored. The centralized network management system 30 is configured to perform corresponding processing according to the network alarm item data table after receiving the network alarm ID from the first collection unit 11 or the second collection unit 21.

The network management system of one embodiment of the present invention has been described above with reference to Fig. 1. Referring now to Fig. 2, a centralized network management system alarm processing method according to an embodiment of the present invention will be further described. Among them, in order to make the article clean, the related contents of the mapping table and the network alarm item data table which have been described above are not repeated.

As shown in the figure, first, in step 200, the collecting unit of the network element supporting the first version or the second version collects the network element alarm of the corresponding version, for example, the first collecting unit 11 supporting the first version collects the 1.0 version network element 10 The No. 1 alarm, and the second acquisition unit 21 supporting the second version collects the No. 1 alarm of the 1.1 version of the network element 20. Then, the process proceeds to step 210.

In step 210, the network alarm ID corresponding to the network element alarm ID is determined according to the network element alarm item and the network alarm item mapping table stored in the first collection unit 11 or the second collection unit 21, and the network alarm ID is reported. The centralized network management system 30; that is, the first collection unit 11 supporting the first version, according to the mapping relationship of the network element side alarm item data mapping table in the network element version 1.0 in Table 2, the collected 1.0 version network element The alarm No. 1 of 10 is converted to the network alarm ID 1001 and then sent to the centralized network management system 30, and the second acquisition unit 21 supporting the second version is based on the version 1.1 of the network element side alarm data mapping table in Table 5. The mapping relationship is obtained by converting the collected alarm No. 1 of the 1.1 network element 20 into a network alarm ID of 2001 and reporting it to the centralized network management system 30. Next, the process proceeds to step 220.

In step 220, the centralized network management system 30 finds the corresponding network alarm ID in the network alarm item data table, and performs corresponding processing. That is to say, the alarm for the network alarm ID 1001 and the network alarm ID received by the centralized network management system are alarms of 2001, and the centralized network management system can know that the former is a temperature alarm with an emergency level according to the data of Table 7. ", while the latter is "level is an important temperature alarm", and then the centralized network management system 30 performs corresponding processing.

Similarly, when the first collecting unit 11 collects other alarms of the 1.1 version network element 10 and the second collecting unit 21 collects the 1.1 version of the network element 20, the system processing method also proceeds according to the above solution of the present invention. OK, for the sake of conciseness of the article, it will not be repeated.

It can be seen from the foregoing solution of the present invention that the network side alarm data of the 1.1 version is fully compatible with the lower version of the data, thereby achieving the requirement of centralized network management, and simultaneously performing alarm data of different versions of the same type of network element device. deal with.

Although the present invention has been illustrated and described with reference to the preferred embodiments of the present invention, those skilled in the art The spirit and scope of the invention is defined by the appended claims.
