Description

Technical Field

[0001] The present application relates to the field of communication network technology, and in particular to a communication network early warning method, system and related equipment. Background Art

[0002] In a communication network, the transmission of network data depends on the cooperation of various node devices in the communication network. If a node device in the communication network fails, it will at least affect the node devices with which it has a topological connection relationship, and at worst it may cause the topological network where the failed node device is located to be paralyzed.

[0003] In actual applications, the communication network can be monitored. If a faulty node device is detected, an alarm message will be sent to the operation and maintenance center to prompt the faulty node device. The operation and maintenance personnel will determine the early warning information about the topology network according to the specific structure of the topology network, so that the topology network can be operated and maintained in advance to minimize the economic and property losses caused by the faulty node device.

[0004] In actual operation, the topology network can be determined by the network service provider, but the network service provider usually does not provide the specific structure of the topology network to the outside world, resulting in operation and maintenance personnel having to rely on the specific structure of the topology network provided by a third-party system to determine warning information. Summary of the Invention

The following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without creative work.

[0038] In the prior art, the specific structures of topological networks include at least: bus network, star network and ring network; bus network refers to a network topology structure formed by connecting multiple node devices with a line; star network refers to a network topology structure formed by each node device being connected to a central device with a separate line; ring network refers to a network topology structure formed by connecting all node devices into a ring;

[0039] After the specific structure of the topology network is determined, it indicates that the node devices included in the topology network and the topology connection relationships between the node devices have been correspondingly determined.

[0040] If a node device in a topology network fails, the failure of the failed node device will also affect other node devices in the topology network and may even affect the entire topology network in which it is located. Therefore, in principle, while repairing the failed node device, the operation status of the entire topology network can be checked in advance to prevent the topology network from being paralyzed.

[0041] In practical applications, existing communication network early warning methods mainly include the following steps:

[0042] 1) The Operations and Maintenance Center (OMC) receives alarm information from the Network Management System (NMS);

[0043] 2) The operation and maintenance personnel of the operation and maintenance center determine the information of the faulty node device indicated by the alarm information; the information of the faulty node device generally includes: the name of the faulty node device, the physical geographical location of the faulty node device (such as Building XX), and the time when the fault occurred;

[0044] 3) The operation and maintenance personnel determine the topology network where the faulty node device is located and the node position of the faulty node device in its topology network according to the specific structure of the topology network, and subsequently generate early warning information based on this.

[0045] Based on practical experience, although the above technical solution can realize fault monitoring of topological networks, it has several application limitations, as shown below:

[0046] 1) The specific structure of the topology network needs to be provided by a third-party system (such as an Internet service provider). If the third-party system cannot provide the specific structure of the topology network, it is impossible to independently determine the specific structure of the topology network through existing technical means.

[0047] 2) Alarm analysis and warning generation must be performed offline by operations and maintenance personnel, resulting in significant lags in the execution of these steps, further leading to low monitoring efficiency.

[0048] 3) Since operation and maintenance personnel are prone to human errors when performing steps such as analyzing alarm information and generating early warning information, erroneous early warning information may be obtained;

[0049] In summary, existing communication network early warning methods have technical problems such as relying on the specific structure of the topological network provided by a third-party system to determine early warning information, low monitoring efficiency, and poor accuracy of early warning information.

[0050] In order to solve the above technical problems, the present application proposes a technical solution for early warning of communication networks. The solution is applied to a communication network early warning system 100. The communication network early warning system 100 is set in an operation and maintenance center. The communication network early warning system 100 communicates with the network management system 200 through the OMC northbound interface of the operation and maintenance center.

[0051] like Figure 1 As shown, Figure 1 The schematic diagram of the structure of the communication network early warning system provided in the embodiment of the present application shows that the communication network early warning system 100 includes: a data acquisition module 110, a connection diagram construction module 120, and an early warning module 130. The data acquisition module 110 has two functions: the first function is to receive network topology data of the communication network and device information of node devices of each communication subnet in the communication network sent by the network management system 200 according to a preset period through the OMC northbound interface; the second function is to receive alarm information about the communication subnet determined by the network management system 200 based on actual conditions and sent irregularly through the OMC northbound interface; in actual applications, the preset period can be set to one natural day.

[0052] The connection diagram construction module 120 is used to construct a full-path topology connection diagram based on the topology connection data set, and the full-path topology connection diagram displays the topology network in the communication subnet; the early warning module 130 is used to determine early warning information based on the received alarm information.

[0053] In summary, it can be seen that in the technical solution for early warning of communication networks proposed in the present application, since the specific structure of the topology network can be automatically determined through the received network topology data and node device information, the technical solution of the present application does not rely on the specific structure of the topology network provided by a third-party system; in addition, the communication network early warning system 100 in the present application can also automatically analyze the received alarm information in a timely manner and automatically generate early warning information indicating the topology network where the faulty node device is located and the node position of the faulty node device in the topology network.

[0054] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0055] First, the embodiment of the present application proposes a communication network early warning method, such as Figure 2 As shown, Figure 2 A flow chart of a communication network early warning method provided in an embodiment of the present application, the method comprising:

[0056] S310~S330, details are as follows:

[0057] S310: Determine a topology connection data set of each communication subnet based on the network topology data of the communication network and the device information of the node devices of each communication subnet in the communication network;

[0058] The elements in the topological connection data set are two node devices having a topological connection relationship.

[0059] Specifically, in the embodiment of the application, the network topology data of the communication network and the device information of the node devices are both collected by the data collection module 110 from the network management system 200 .

[0060] The network topology data indicates the topological connection relationship between two node devices in the topological network; for example, for a topological network with four node devices A, B, C and D connected in sequence, there is a topological connection relationship between node device A and node device B, and there is a topological connection relationship between node device B and node device C; it should be noted that if the topological network is an open-loop network, there is also a topological connection relationship between node device D and node device A.

[0061] Each topological connection relationship corresponds to a network topology data. The data format of the network topology data is as follows:

[0062] {TOPOLINK_NAME, SOURCE NODE, SOURCEPORT, END NODE, ENDPORT};

[0063] Wherein, TOPOLINK_NAME represents the name of the topological connection relationship, which is used to uniquely identify a topological connection relationship in each communication subnet in the communication network; SOURCE NODE represents the source node (i.e., source node device) in the topological connection relationship, which is the node that sends network data;

[0064] SOURCEPORT represents the source port (a network port in the source node device), which is used to send network data; ENDNODE represents the end node (end node device) in the topology connection relationship, which is the node that receives network data; ENDPORT represents the end port (a network port in the end node device), which is used to receive network data.

[0065] Device information is the identification information of the node devices included in each communication subnet in the communication network. Each node device corresponds to a piece of device information. The data format of the device information is as follows:

[0066] {SUBSYSTEMNAME, NE_ID};

[0067] SUBSYSTEMNAME indicates the name of the communication subnet; NE_ID indicates the ID of the node device.

[0068] It should be emphasized that the "network topology data and device information" collected above include data corresponding to open-loop networks (mainly referring to non-ring topology networks such as bus networks and star networks) and ring networks respectively; among them, the topological connection relationship includes the topological connection relationship in the open-loop network, and also includes the topological connection relationship in the ring network; the device information includes the information of the node devices in the open-loop network, and also includes the information of the node devices in the ring network.

[0069] In actual operation, after the data acquisition module 110 receives the network topology data and device information sent by the network management system 200, the data acquisition module 110 determines the topology connection data set of each communication subnet based on the network topology data and device information and the pre-stored ID of the source node device and the ID of the end node device;

[0070] The data format of the topological connection dataset is as follows:

[0071] SUBSYSTEM1={SOURCE NODE1, END NODE1; SOURCE NODE2, END NODE2; SOURCENODE3, END NODE3;...};

[0072] SUBSYSTEM2={SOURCE NODE1, END NODE1; SOURCE NODE2, END NODE2; SOURCENODE3, END NODE3;...};

[0073] Among them, SUBSYSTEM1 and SUBSYSTEM2 represent different communication subnets;

[0074] "SOURCE NODE1, END NODE1" represents a source node device and an end node device with a topological connection relationship in a communication subnet, SOURCE NODE1 represents the source node device in the topological connection relationship, and END NODE1 represents the end node device in the topological connection relationship; in the embodiment of the present application, the above "1" and "2" are used to distinguish different topological connection relationships.

[0075] S320: Constructing a full-path topology connection graph based on the topology connection dataset;

[0076] Among them, the full path topology connection diagram shows the topology network in the communication subnet.

[0077] Specifically, any two adjacent node devices in a ring network have a topological connection relationship; taking a ring network with four node devices A, B, C and D connected in sequence as an example, there is a topological connection relationship between node device A and node device B,..., and between node device D and node device A; as for an open-loop network that also has four node devices A, B, C and D connected in sequence, there is no topological connection relationship between node device D and node device A.

[0078] Based on the above distinctions, the open-loop network and ring network corresponding to each communication subnet can be determined separately according to the topological connection data set of each communication subnet; the full-path topological connection diagram can not only display the topological connection relationship between multiple node devices in each topological network, but also display the position of the node device in the topological network; since a communication subnet may include multiple topological networks, a full-path topological connection diagram may display multiple topological networks, so the full-path network topology diagram can intuitively display the various node devices included in each topological network in multiple topological networks.

[0079] In one implementation, S320 includes steps (1) to (2), as detailed below:

[0080] Step (1): determining multiple topologically adjacent data sets based on the topologically connected data sets;

[0081] The elements in the topology adjacency data set are node devices, and the arrangement order of all elements in the topology adjacency data set indicates the connection order of multiple node devices in the topology network.

[0082] Specifically, the purpose of confirming the topology adjacency data set is to determine the specific structure of all topology networks in each communication subnet. The network topology may be an open-loop network or a ring network, that is, each topology adjacency data set corresponds to an open-loop network or a ring network.

[0083] In one implementation, the device information of the node device includes: the level of the node device; in addition, step (1) includes: steps (1.1) to (1.2), the details of which are as follows:

[0084] Step (1.1): According to the device information, the node device with the highest level among the multiple node devices included in the topology connection data set is determined as the endpoint node device.

[0085] Specifically, network data in an open-loop network is transmitted in a "straight line", so the network endpoints of an open-loop network are easier to identify; network data in a ring network is transmitted in a "ring";

[0086] If each communication subnet has only one ring network, the determination process will be relatively simple. However, in actual situations, the network topology structure of the communication subnet may be very complex. For example, the communication subnet may include multiple open-loop networks and multiple ring networks. Furthermore, there may be multiple ring networks in the communication subnet that are interconnected through certain node devices. This results in the communication subnet's multiple topological connection relationships corresponding to the ring structure being usually redundant and difficult to organize. If the topological adjacency data set is determined by traversal, the workload will be very huge.

[0087] In order to improve the efficiency of determining the topological adjacency data set, the embodiment of the present application selects an endpoint node device from multiple node devices, and subsequently determines the topological network through the endpoint node device as the entry point; in the embodiment of the present application, the node device with a higher level in each communication subnet is determined as the endpoint node device. If there are multiple node devices with the same level in the communication subnet, any one can be selected; it should be emphasized that when selecting the endpoint node device, the backbone layer device or the access layer device is selected, as shown in Table 1. Table 1 is an example table of the levels of each node device in the communication subnet provided by the embodiment of the present application, where OSN9600 is the model of the device; the multiple node devices with different models shown in Table 1 are all backbone layer devices or access layer devices; in actual operation, the level of the node device can be determined according to actual needs.

[0088] Table 1 Example of the level of each node device in the communication subnet

[0089] level Device Model Level 1 OSN9600 / OSN9500 / OSN8800 / OSN7500 / OSN3500 Level 2 OSN6800 / OSN3500 / Metro5000 Level 3 OSN2500 / OSN1800 / OSN1500 / Metro3000 / Metro1000

[0090] Step (1.2): determining a plurality of topologically adjacent data sets based on the topologically connected data sets and the endpoint node devices;

[0091] The endpoint node devices in the topology adjacency data set are located at the start point and / or end point of the connection sequence.

[0092] Specifically, after the endpoint node device is determined, the first topology connection relationship including the endpoint node device is first selected from the topology connection data set, and then the second topology connection relationship including another node device in the first topology connection relationship is selected from the topology connection data set, and so on, until the other node device in the selected topology connection relationship is the endpoint node device, or no topology connection relationship can be selected from the topology connection data set based on the other node device;

[0093] For example, assuming that the endpoint node device is A; after determining the endpoint node device A, first select the first topology connection relationship including the endpoint node device A from the topology connection data set. The first topology connection relationship includes: topology connection relationships (A, B), (A, C), and (A, D). Then, select the second topology connection relationship including the node device B, the node device C, and the node device D from the topology connection data set, and so on, until the selected topology connection relationship is (F, A) or (F, K).

[0094] Among them, (F, A) indicates the situation that "the other node device in the selected topological connection relationship is an endpoint node device", that is, the node device of the next topological connection relationship can be selected as the endpoint node device A. The topological adjacency data set determined by ending in this situation corresponds to a ring network; (F, K) indicates that "the topological connection relationship can no longer be selected in the topological connection data set based on the other node device", that is, the topological connection relationship including node device K can no longer be selected in the topological connection data set based on node device K. The topological adjacency data set determined by ending in this situation corresponds to an open-loop network.

[0095] Now, based on the above example, we will explain the meaning of "the endpoint node device in the topological adjacency data set is located at the starting point and / or end point of the connection order". When the process of determining the topological adjacency data set ends with the situation (F, A), it indicates that the endpoint node device A is located at both the starting point and the end point of the connection order; when the process of determining the topological adjacency data set ends with the situation (F, K), it indicates that the endpoint node device A is only located at the starting point or the end point of the connection order.

[0096] After selecting the above multiple topological connection relationships, the topological adjacency dataset can be determined accordingly. In actual operation, the topological adjacency dataset can be stored or displayed in the form of an adjacency table, such as Figure 3 and Figure 4 As shown, Figure 3 This is a partial example diagram of the adjacency table provided in the embodiment of the present application. Each data in the adjacency table corresponds to a node device, such as Figure 4 As shown, Figure 4 An example diagram of multiple adjacency tables provided in an embodiment of the present application, where each row corresponds to a topological network; in actual operation, the adjacency table can also represent the hierarchical information of each node device in the topological network.

[0097] according to Figure 3It can be seen that the data format of the first data in the adjacency table is [data, firstarc]. Data represents the data field, which is used to store the node device information of the endpoint node device. The node device information includes not only the configuration information of the node device but also the level of the node device. The specific situation can be determined according to actual needs. Firstarc represents the pointer field, which is used to send a pointer to the next data.

[0098] The data formats of the second and third data in the adjacency list are both [adjvex, info, nextarc]. Both adjvex and nextarc represent pointer fields. adjvex is used to receive the pointer to the previous data, and nextarc is used to send the pointer to the next data. Info represents the data field, which stores the node device information of the intermediate node device. The intermediate node device is a node device that is not at the network endpoint in the topology network.

[0099] according to Figure 4 As can be seen, the adjacency table is used to display all the topological connection relationships in each communication subnet. The order of each data in each row of the adjacency table indicates the hierarchical order of the node devices corresponding to each data. The details are as follows:

[0100] SUBSYSTEM1{OSN3500[data, firstarc], SDH1[adjvex, info, nextarc], SDH5[adjvex, info, nextarc], SDH9[adjvex, info, nextarc], OSN3500[adjvex, info, nextarc];

[0101] OSN3500[data, firstarc], SDH2[adjvex, info, nextarc], SDH6[adjvex, info, nextarc], SDH10[adjvex, info, nextarc], OSN3500[adjvex, info, nextarc];

[0102] OSN3500[data, firstarc], SDH3[adjvex, info, nextarc], SDH7[adjvex, info, nextarc], OSN3500[adjvex, info, nextarc];

[0103] OSN3500[data, firstarc], SDH3[adjvex, info, nextarc], SDH7[adjvex, info, nextarc], SDH11[adjvex, info, nextarc], SDH13[adjvex, info, nextarc];

[0104] OSN3500[data, firstarc], SDH4[adjvex, info, nextarc], SDH8[adjvex, info, nextarc], SDH12[adjvex, info, nextarc]}.

[0105] Step (2): Determine the full path topology connection graph based on multiple topology adjacency data sets.

[0106] Specifically, after determining multiple topological adjacency data sets, a full-path topological connection diagram can be constructed based on the open-loop networks and ring networks indicated in each topological adjacency data set, which is used to clearly mark the topological connection relationship between each node device in each open-loop network and ring network, as well as the position of each node device in the open-loop network and / or ring network.

[0107] In one implementation, step (2) includes steps (2.1) to (2.2), the details of which are as follows:

[0108] Step (2.1): Determine an initial path topology connection graph based on multiple topological adjacency data sets;

[0109] The initial path topology connection graph includes a plurality of topology networks that correspond one-to-one to a plurality of topology adjacency data sets.

[0110] Specifically, if Figure 5 As shown, Figure 5 This is an example diagram of an initial topology connection diagram provided in an embodiment of the present application. The device model OSN3500 in the embodiment of the present application (hereinafter referred to as OSN3500 device) is a backbone layer device or an access layer device, and is also an endpoint node device in the full path topology connection diagram. SDH (Synchronous Digital Hierarchy) is used in the embodiment of the present application to represent the aggregation layer device.

[0111] Figure 5The displayed initial topology connection diagram includes three ring networks on the left and two open-loop networks on the right, such as the open-loop network OSN3500-SDH4-SDH8-SDH12 and the ring network OSN3500-SDH2-SDH6-SDH10-OSN3500. Among them, the SDH1 device, SDH2 device and SDH3 device represent intermediate node devices in the full-path topology connection diagram, and the SDH12 device and SDH13 device represent another endpoint node device of the open-loop network in the full-path topology connection diagram except the OSN3500 device.

[0112] Step (2.2): Based on the topological sorting algorithm, perform topological sorting on the initial path topology connection graph to obtain the full path topology connection graph.

[0113] Specifically, in actual operation, the open-loop network and the ring network in each communication network may be interconnected, that is, there are node devices located in both the open-loop network and the ring network. Therefore, in order to make the full-path topology connection diagram determined by step (2.1) more clearly show the topological connection relationship between multiple node devices in the communication subnet and the position of the node devices in the topology network, it is necessary to perform topological sorting processing on the initial path topology connection diagram based on the topological sorting algorithm to obtain the full-path topology connection diagram, and deduplicate the interconnected node devices to obtain the full-path topology connection diagram, as shown in FIG. Figure 6 As shown, Figure 6 This is an example diagram of the full path topology connection diagram provided in the embodiment of the present application, compared to Figure 5 The SDH3 and SDH7 devices do not form a ring network with OSN3500 alone, but use the SDH3-SDH7 in the open loop network OSN3500-SDH3-SDH7-SDH11-SDH13 to show a ring network. Figure 6 Sorting and deduplication have been done, so you can Figure 6 Clearly determine the connection relationship between node devices in open-loop and ring networks, as well as the location of node devices in the topological network.

[0114] according to Figure 5 and Figure 6It can be seen that the full-path topology connection diagram is determined corresponding to the backbone layer equipment. Therefore, in actual operation, when only one full-path topology connection diagram is determined and it is impossible to exhaust all the topology connection relationships in the communication subnet, that is, there are still remaining topology connection relationships that have not been used, and / or, when a communication subnet has multiple different backbone layer devices or access layer devices (the models can be the same, such as all OSN3500), it indicates that another full-path topology connection diagram needs to be determined for the communication subnet, and step (1.1) needs to be repeated until all topology connection relationships are utilized; it should be noted that when repeating step (1.1), the endpoint node device needs to be re-determined and it is ensured that the re-determined endpoint node device is not determined as the endpoint node device in the aforementioned process of determining the full-path topology connection diagram.

[0115] After the full path topology connection diagram is determined, a topology network information table can also be created based on the full path topology connection diagram, as shown in Table 2. Table 2 is an example table of the topology network information table provided in an embodiment of the present application.

[0118] Where HUAN_ID represents the ID of the topology network in the communication subnet;

[0119] HUAN_NAME indicates the name of the topology network in the communication subnet;

[0120] SOURCE NODE indicates the source node device in the topology network in the communication subnet, SOURCE TYPE indicates the type of the source node device, SOURCE_NE indicates the device information of the source node device, and UPDATE TIME indicates the update time; in actual operation, the update time may be the update time of the topology network information table.

[0121] In practical applications, once the above data are determined, they can be stored in a corresponding database.

[0122] S330: In response to receiving the alarm information, if the faulty node device indicated by the alarm information is a node device in the full path topology connection graph, determine early warning information according to the full path topology connection graph;

[0123] The warning information includes: the topological network where the faulty node device is located and the node position of the faulty node device in the topological network.

[0124] Specifically, when the data acquisition module 110 receives the alarm information sent by the network management system 200, it must first determine whether the faulty node device indicated by the alarm information is a node device in the full-path topology connection diagram. During the determination process, all full-path topology connection diagrams need to be traversed; if the determination result is that the faulty node device indicated by the alarm information is a node device in the full-path topology connection diagram, the early warning information indicating the node location of the faulty node device is determined according to the full-path topology connection diagram.

[0125] In one implementation, the types of alarm information include: alarm information includes: active alarm and clear alarm, active alarm is used to indicate that there is a faulty node device in the communication subnet, clear alarm is used to indicate the clearing of historical warning information; Figure 7 As shown, Figure 7 The flowchart of S330 provided in the embodiment of the present application includes S3301 to S3305, and the details are as follows:

[0126] S3301: Determine whether the alarm information is an active alarm or a cleared alarm.

[0127] Specifically, the alarm information does not always indicate that a faulty node device has appeared in the communication subnet. In actual operation, the alarm information includes: active alarms and cleared alarms; among them, active alarms are used to indicate that a faulty node device has appeared in the communication subnet, and cleared alarms are used to indicate the clearing of historical active alarms; that is, active alarms are used to "warn of danger" and cleared alarms are used to "declare safety."

[0128] S3302: If the alarm information is an active alarm, determine whether the faulty node device indicated by the active alarm is a node device in the full path topology connection diagram.

[0129] Specifically, if it is determined that the alarm information is an active alarm, it is necessary to determine whether the faulty node device indicated by the active alarm is a node device in the full-path topology connection diagram. If the faulty node device is not in the full-path topology connection diagram, it means that a faulty node device has appeared in other communication networks, so the active alarm is directly ignored.

[0130] S3303: If the faulty node device indicated by the active alarm is a node device in the full path topology connection diagram, determine whether there is historical warning information about the faulty node device.

[0131] Specifically, the warning information generated by the embodiment of the present application is associated with the faulty node device. A faulty node device only needs one warning information for warning, that is, there will be no situation where the faulty node device indicated by two consecutive warning messages is the same faulty node device. Therefore, even if an active alarm is received, warning information will not be generated immediately based on the active alarm. It is necessary to determine whether warning information can be generated based on the active alarm based on historical warning information.

[0132] In actual operation, since the warning information needs to indicate the node location of the faulty node device, after determining that the faulty node device indicated by the active alarm is a node device in the full path topology connection diagram, it is possible to determine whether the faulty node device indicated by the active alarm exists in the historical warning information and whether the faulty node device indicated by the historical warning information is the same as the faulty node device indicated by the active alarm, that is, to determine whether there is historical warning information about the faulty node device.

[0133] In actual operation, due to the degree of failure of the faulty node device and the urgency of repair, the alarm information indicating the same faulty node device may be sent multiple times. If it is determined that there is historical warning information about the faulty node device, even if the alarm information about the faulty node device is received multiple times, there is no need to generate new warning information.

[0134] S3304: If there is historical warning information about the faulty node device, associate the active alarm with the historical warning information.

[0135] Specifically, if it is determined that there is historical warning information about the faulty node device, it is only necessary to associate the active alarm with the historical warning information, and there is no need to generate new warning information.

[0136] It should be emphasized that although there is no need to generate new warning information, this application does not limit the frequency of publishing historical warning information. That is, if warning information indicating the same faulty node device is received again, the corresponding historical warning information can be published again to remind relevant operation and maintenance personnel.

[0137] S3305: If there is no historical warning information about the faulty node device, a step of determining warning information indicating a node location of the faulty node device according to the full path topology connection diagram is executed.

[0138] Specifically, if there is no historical warning information about the faulty node device, the step of determining the warning information indicating the node location of the faulty node device based on the full-path topology connection diagram is executed, that is, new warning information is generated, and the warning information is subsequently released, so that relevant operation and maintenance personnel can quickly perform advance operation and maintenance on the topology network based on the warning information.

[0139] In one implementation, Figure 7 As shown, S330 also includes: S3306 to S3308, the details of which are as follows:

[0140] S3306: If the alarm information is a clear alarm, determine whether the clear alarm is used to clear historical active alarms.

[0141] Specifically, in the embodiment of the present application, the communication network early warning system 200 needs to be instructed by the clear alarm sent by the network management system 100 to clear the historical activity alarm, because "whether the faulty node device has been repaired" is the information determined by the communication network early warning system 100 in the embodiment of the present application, but whether the repaired faulty node device can be used normally needs to be determined by the network management system 100; if the network management system 100 sends a clear alarm about the historical activity alarm, it indicates that the faulty node device indicated by the historical activity alarm has been put into normal use, and the corresponding historical activity alarm can be cleared.

[0142] In actual operation, clear alarms can be used to indicate the clearing of multiple alarm information. Therefore, it is first necessary to determine whether the received clear alarm is used to indicate the clearing of historical activity alarms of the faulty node device. If the clear alarm is not used to indicate the clearing of historical activity alarms, the communication network early warning system 200 will ignore the clear alarm.

[0143] S3307: If the clear alarm is used to clear historical activity alarms, determine whether all historical activity alarms have been cleared.

[0144] Specifically, because the network management system 100 may send multiple active alarms about the same faulty node device, one faulty node device may correspond to multiple historical active alarms.

[0145] If it is determined that the clear alarm is used to clear historical activity alarms, based on the faulty node device indicated by the clear alarm (which has been confirmed to be repaired successfully at this time) and the faulty node devices indicated by multiple historical activity alarms, determine whether there is a historical activity alarm corresponding to the clear alarm. If so, it means that the historical activity alarms have not been completely cleared.

[0146] S3308: If all historical activity alarms have not been cleared, clear the historical activity alarms.

[0147] Specifically: if it is determined that the historical activity alarm corresponding to the clear alarm has not been cleared or has not been completely cleared, the communication network early warning system 200 clears the historical activity alarm according to the clear alarm.

[0148] In one implementation, the device information includes: pigtail data of the node device; S330 also includes: steps (3) to (5), the details of which are as follows:

[0149] Step (3): Determine the fault node device and the time when the fault occurred indicated by the alarm information.

[0150] Specifically, the active alarm generally includes identification information and geographic location of the faulty node device and the time when the faulty node device fails, that is, the fault occurrence time.

[0151] It should be emphasized that the geographic location indicates a location in a social space, such as the location information of "xxx Street".

[0152] In the prior art, although the active alarm can clear the physical information indicating the faulty node device, it cannot tell the relationship between the faulty node device and the communication network, resulting in the inability to determine the topological network information such as the faulty node device.

[0153] Step (4): According to the alarm information and the full path topology connection diagram, determine the topology network where the faulty node device is located in the full path topology connection diagram and the location information of the faulty node device in the topology network.

[0154] Specifically, in an embodiment of the present application, since the full-path topology connection diagram of each communication subnet has been pre-constructed, when an active alarm is received, the ID of the faulty node device can be determined based on the identification information and the geographical location, and then the faulty node device can be determined in the full-path topology connection diagram based on the ID, and the open-loop network or ring network where the faulty node device is located in the full-path topology connection diagram and the location information of the faulty node device in the open-loop network or ring network can be determined.

[0155] Step (5): Determine the warning information based on the fault occurrence time, location information and topological network of the fault node device.

[0156] Specifically, after determining the location information and the open-loop network or ring network in which it is located, the warning information is determined in combination with the time of occurrence of the fault; the warning information can issue a warning for the topological network where the faulty node device is located, and the operation and maintenance personnel can check the remaining node devices in the topological network except the faulty node device to determine whether they are affected by the faulty node device.

[0157] In one implementation, the warning information further includes: fault service information; and between step (4) and step (5) further includes: step (6) to step (8), the details of which are as follows:

[0158] Step (6): Based on the pigtail data, determine the dedicated line services and base station services supported by all node devices in the open-loop network or ring network where the faulty node device is located.

[0159] Specifically, the fiber pigtails are used in the communication network to connect different node devices, such as servers, switches and routers; in the embodiment of the present application, the fiber pigtail data of the fiber pigtails between each node device is pre-stored in the communication network early warning system 200. After determining all the node devices in the open-loop network or ring network where the faulty node device is located, the dedicated line services and base station services supported by the above-mentioned node devices can be determined based on the fiber pigtail data.

[0160] Step (7): Determine whether there is any faulty service in the dedicated line service and base station service.

[0161] Specifically, after determining the dedicated line services and base station services supported by all node devices, it can be determined whether the dedicated line services and base station services are affected, and the affected dedicated line services and / or base station services are determined as faulty services.

[0162] Step (8): Determine the fault service information of the fault service based on the preset service information of the dedicated line service and the base station service.

[0163] Specifically, after determining the faulty service, the faulty service information including the fault scope and impact degree of the faulty service can be further determined, and then the faulty service information can also be included in the scope of the early warning information, so that the early warning information can be used for a large-scale early warning from point to line, and then from line to surface for each communication subnet in the communication network;

[0164] Among them, "point" refers to the faulty node device indicated by the alarm information, "line" refers to the open-loop network or ring network where the faulty node device is located, and "surface" refers to the dedicated line services and base station services supported by all node devices included in the open-loop network or ring network where the faulty node device is located.

[0165] In summary, the communication network early warning method provided by the embodiment of the present application can automatically construct a full-path topology connection diagram through the received network topology data and node device information, so the technical solution of the present application does not rely on the network topology structure provided by a third-party system; in addition, the embodiment of the present application can also automatically analyze the received alarm information in a timely manner and automatically generate early warning information including the topological network where the faulty node device is located and the node position of the faulty node device in the topological network; it can be seen that the communication network early warning method provided by the embodiment of the present application can solve the technical problems of the existing communication network early warning method that it needs to rely on the specific structure of the topological network provided by a third-party system to determine the early warning information, the monitoring efficiency is low, and the accuracy of the early warning information is poor.
