[0002] Fixed broadband user access networks involve equipment such as optical line terminals (OLTs), primary optical splitters, and secondary optical splitters. While OLTs possess monitoring capabilities, these capabilities are limited and cannot detect potential faults in the fixed broadband access network, which could cause frequent disconnections for users. Secondary and primary optical splitters are passive devices without their own monitoring capabilities, making them unsuitable for monitoring the operational status of traditional equipment monitoring methods.

[0003] How to detect various potential faults in fixed broadband access networks in a timely and effective manner is a technical problem that needs to be solved. Summary of the Invention

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The drawing numbers in this application are only used to distinguish the various steps in the solution and are not used to limit the execution order of the various steps. The specific execution order is subject to the description in the specification.

[0051] To address the problems existing in the prior art, this application provides a method for monitoring faults in a fixed broadband access network. Figure 1 This is a flowchart illustrating the fixed broadband access network fault monitoring method according to an embodiment of this application.

[0052] like Figure 1 As shown, it includes the following steps:

[0053] Step 102: Obtain relevant equipment information of the access network devices that the user passes through when accessing the fixed broadband network and the user's online / offline information;

[0054] Step 104: Based on the relevant device information of the access network device and the online / offline information, monitor the actual number of online users carried by the target access network device at preset time intervals;

[0055] Step 106: Based on the actual number of online users at the current monitoring time and a preset threshold, determine the decrease in the number of online users of the target access network device at the current monitoring time. The preset threshold is determined based on the historical number of online users of the target access network device.

[0056] Step 108: When the decrease in the number of online users exceeds the first preset safety threshold, it is determined that the target access network device is faulty.

[0057] In step 102, it can be combined with Figure 2 Describe the access network devices that a user passes through when accessing a fixed broadband network. Figure 2 This is a schematic diagram of the architecture of a fixed broadband access network device according to an embodiment of this application.

[0058] like Figure 2 As shown, there are multiple users on the user side. When user 1 accesses the fixed broadband network, it will sequentially connect to the authentication server through the corresponding Optical Network Unit (ONU) 1, secondary optical splitter 1, primary optical splitter 1, OLT device, Broadband Remote Access Server (BRAS) 1 or BRAS 2, and then connect to the fixed broadband network after authentication.

[0059] Similarly, other users n connect to the authentication server sequentially through the corresponding ONUn, secondary splitter n, primary splitter n, OLT device, BRAS1 or BRAS2, thereby enabling access to the fixed broadband network.

[0060] The aforementioned access network equipment is divided into active devices and passive devices. For example, the primary optical splitter and the secondary optical splitter are passive devices, the OLT equipment is an active device, and the ONU includes both active and passive devices.

[0061] If any of the above devices malfunctions, it can lead to potential problems with the fixed broadband access network. These potential problems can cause users to frequently experience disconnections while accessing the network, causing inconvenience to users.

[0062] Therefore, this application proposes to monitor whether the target access network device has a fault by extracting relevant device information of these access network devices and user online / offline information.

[0063] The methods for obtaining device information from access network devices differ between active and passive devices. Specifically, for active devices such as OLTs and ONUs, the relevant device information of the access network devices traversed when a user accesses the fixed broadband network is obtained, including: real-time acquisition of relevant device information of each access network device traversed by the target user when accessing the fixed broadband network based on the Point-to-Point Protocol over Ethernet (PPPoE+). For passive devices such as optical splitters and ONUs, the relevant device information obtained is the device's dummy resource information. The following will describe this in detail with reference to different embodiments.

[0064] In one embodiment, the access network device includes an optical line terminal (OLT) device, an OLT board, and a passive optical network (PON) port of the OLT device. The relevant device information of the access network device includes user account information, the IP address of the OLT device, the slot number of the OLT board, and the port number of the PON port.

[0065] Figure 3 Examples of access network device information fields from embodiments of this application are provided, such as... Figure 3As shown, the relevant equipment information of the access network equipment includes user account, user online IP, BRAS IP, BRAS port, OLT IP, frame number, OLT board slot number, OLTPON port number, ONU serial number, ONU port number, etc.

[0066] In one embodiment, the access network device includes a primary optical splitter and a secondary optical splitter. The relevant device information of the access network device includes the dumb resource information of the optical splitter, and the dumb resource information records the association relationship between users and optical splitters.

[0067] Figure 4 An example of dumb resource information for a beam splitter according to an embodiment of this application is given, such as... Figure 4 As shown, the dummy resource information of the optical splitter includes the user account, the name of the optical splitter accessed by the user to the network, the optical splitter port, the device level of the optical splitter (i.e., whether it is a primary or secondary optical splitter), the name and port of the corresponding uplink optical splitter, and the name and port of the corresponding uplink OLT device. Through the dummy resource information of the optical splitter, the association between the primary and secondary optical splitters traversed by the target user when accessing the network and the corresponding user and OLT device can be determined.

[0068] Optionally, obtaining user online / offline information when a user accesses a fixed broadband network includes: obtaining the target user's online information based on the billing start message generated when the target user accesses the fixed broadband network; and obtaining the target user's offline information based on the billing end message generated when the target user leaves the fixed broadband network.

[0069] If a target user is authenticated and allowed to use the network, an accounting start request will be sent to the authentication server. The authentication server will respond to the accounting start request by generating an accounting start message and will add the online user to the online user count. If a network device malfunctions, causing the target user to go offline, an accounting end request will be sent to the authentication server. The authentication server will respond to the accounting end request by generating an accounting end message and will remove the offline user from the online user count.

[0070] In an embodiment where the access network equipment includes an optical line terminal (OLT) device, an OLT board, and a PON port, in step 104, based on the relevant equipment information of the access network equipment and the online / offline information, the actual number of online users carried by the target access network equipment is monitored at preset time intervals. This includes: determining the corresponding type of target access network equipment based on the IP address of the OLT device, the slot number of the OLT board, or the port number of the PON port recorded in the relevant equipment information; obtaining the online / offline information of each user account on the target access network equipment based on the user account information corresponding to the target access network equipment; and monitoring the actual number of online users carried by the target access network equipment at preset time intervals based on the online / offline information.

[0071] In an embodiment where the access network device includes a primary optical splitter and a secondary optical splitter, in step 104, based on the relevant device information of the access network device and the online / offline information, the actual number of online users carried by the target access network device is monitored at a preset time interval. This includes: determining the user account information corresponding to the target optical splitter based on the dummy resource information of the access network device; obtaining the online / offline information of each user account on the target optical splitter based on the user account information; and monitoring the actual number of online users carried by the target optical splitter at a preset time interval based on the online / offline information.

[0072] For each target user accessing the network, based on the devices they pass through, the relevant device information of the access network devices associated with that target user is obtained. For example, for active devices such as OLTs, the relevant device information is as follows: Figure 3 As shown, for passive devices such as beam splitters, the relevant equipment information is as follows: Figure 4 As shown.

[0073] Thus, for a target access network device, the user accounts that accessed the fixed broadband network through that device can be found based on the relevant device information. By accessing the user account information, the online / offline status of each user account can be obtained, allowing the query to determine the number of online users at the current monitoring point in time for the target access network device.

[0074] In step 106, the actual number of online users of the target access network device is monitored and compared with a preset threshold to determine the magnitude of the decrease in the number of online users of the target access network device. The preset threshold is determined based on the historical number of online users during normal operation of the target access network device. For example, it can be determined based on the average of periodically generated historical online user counts. Alternatively, it can be calculated by averaging multiple historical online user count data points generated daily or within a predetermined time period under normal operation of the target access network device, and used as the preset threshold for the target access network device.

[0075] In step 108, the calculated decrease in the number of online users at the current monitoring time point of the target access device is compared with a preset safety threshold to determine whether the target access device is faulty. If the decrease in the number of online users exceeds the preset safety threshold, the target access device is determined to be faulty; if the decrease in the number of online users does not exceed the preset safety threshold, the target access device is determined to be operating normally.

[0076] The preset safety thresholds for determining whether each OLT device, OLT board, and PON port is different.

[0077] Optionally, the first preset security threshold includes a first security threshold, a second security threshold, or a third security threshold. When the decrease in the number of online users exceeds the first preset security threshold, determining that the target access network device has a fault includes:

[0078] When the decrease in the number of online users corresponding to the target OLT device exceeds the first safety threshold, it is determined that the target OLT device is faulty.

[0079] When the decrease in the number of online users corresponding to the target OLT board exceeds the second safety threshold, it is determined that the target OLT board is faulty.

[0080] When the decrease in the number of online users corresponding to the target PON port exceeds the third security threshold, it is determined that the target PON port is faulty, wherein the first security threshold is greater than the second security threshold, and the second security threshold is greater than the third security threshold.

[0081] For example, a first safety threshold can be set to 90%–95%, a second safety threshold to 85%–90%, and a third safety threshold to 80%–85%.

[0082] In another embodiment of this application, the presence of a fault can also be determined by the number of high-frequency authentication users carried on the target access network device. Here, the access network device corresponding to the high-frequency authentication users includes OLT devices, OLT boards, and PON ports.

[0083] Optionally, the method further includes: determining the number of times each user goes online and the amount of traffic used within a preset time period based on the online / offline information; determining high-frequency authentication users among the users based on the number of online / offline users and the amount of traffic used; determining the proportion of high-frequency authentication users of the target access network device at the current monitoring time point based on the number of high-frequency authentication users carried by the target access network device and the actual number of online users at the current monitoring time point; and determining that the target access network device has a fault when the proportion of high-frequency authentication users exceeds a second preset security threshold.

[0084] For example, users who successfully log in more than a predetermined number of times per day (e.g., 10-15 times) and whose daily traffic exceeds a predetermined amount (e.g., 10-20M) are identified as high-frequency authentication users. If, at the current monitoring time, the ratio of the number of high-frequency authentication users on the target access network device to the actual number of online users exceeds a preset security threshold, then the access network device is judged to be faulty.

[0085] In one embodiment, a second security threshold can be set to 50%-60%. When the proportion of high-frequency authentication users exceeds this security threshold, the corresponding access network device is determined to be abnormal, and a fault work order can be generated and dispatched to maintenance personnel for handling. When the proportion of high-frequency authentication users drops below 30%-35%, the alarm is restored, and information is pushed to the original work order for related presentation.

[0086] In another embodiment of this application, alarms sent by target access network devices with their own monitoring capabilities can also be used to determine whether the device is faulty. Here, access network devices with their own monitoring capabilities include OLT devices, OLT boards, and PON ports.

[0087] Optionally, the method further includes: upon receiving a target alarm from local monitoring of the target access network device, acquiring the number of first online users carried by the target access network device at a first monitoring time point adjacent to the target alarm time and the number of second online users carried at a second monitoring time point adjacent to the target alarm time; determining the decrease in the number of online users of the target access network device at the second monitoring time point relative to the first monitoring time point based on the first number of online users and the second number of online users; and determining that the target access network device has a fault when the decrease in the number of online users exceeds a third preset safety threshold.

[0088] In this embodiment, the target alarms monitored locally by the target access network device include OLT disconnection or service failure alarms, OLT board and PON port service failure alarms, etc.

[0089] Upon receiving a disconnection or service failure alarm from the target access network device, query the number of online users of the access network device at the two closest intervals before and after the alarm time. If the decrease in the number of online users before and after the alarm time exceeds a preset safety threshold, such as 80-85%, then the alarm is determined to affect the service and constitutes a device failure, and a fault work order process is required.

[0090] When the target access network device issues an OLT device disconnection alarm or a PON passive fiber optic network port outage alarm through local monitoring, the decrease in the number of online users monitored by the target access network device before and after the alarm time is used to further assist in determining whether the alarm issued by the target access network device itself truly affects the service. If it does not affect the service, the subsequent fault work order process can be omitted; otherwise, the alarm can be responded to and the fault handled in a timely manner, improving the efficiency of fault handling after the access network device sends an alarm.

[0091] It should be noted that the access network equipment in this application embodiment may also include an ONU device, thereby enabling the detection of ONU faults or latent faults using the above method. Since the ONU device is closely related to user behavior, such as users actively turning off the power, after excluding cases where users actively turn off the power, the potential faults or latent faults of the ONU can be detected by monitoring the number of online users and the rate of power reduction of the ONU device.

[0092] In this embodiment, by acquiring relevant equipment information of the access network devices that a user passes through when accessing a fixed broadband network and the user's online / offline information; based on the relevant equipment information of the access network devices and the online / offline information, the actual number of online users carried by the target access network device is monitored at preset time intervals; based on the actual number of online users at the current monitoring time point and a preset threshold, the decrease value of the number of online users of the target access network device at the current monitoring time point is determined, the preset threshold being determined based on the historical number of online users when the target access network device is operating normally; when the decrease value of the number of online users exceeds a first preset safety threshold, it is determined that the target access network device has a fault. Thus, faults in fixed broadband access network devices and latent faults of fixed broadband users can be proactively detected, and faults can be handled in a timely manner to prevent users from frequently going online and offline due to network faults, improving the user experience of using the broadband network and providing strong support for existing fault monitoring and management systems.

[0093] Furthermore, the embodiments of this application do not rely on the monitoring capabilities of the access network equipment itself, and can also monitor the operating status of passive devices such as primary optical splitters and secondary optical splitters, thereby solving the problem of monitoring the operating status of passive devices.

[0094] Furthermore, by combining alarms sent by target access network devices with their own monitoring capabilities, it can further assist in determining whether the device is truly affecting services, and decide whether to execute subsequent fault work order procedures, thereby improving the efficiency of fault handling for access network device alarms.

[0095] Optionally, embodiments of this application also provide an electronic device, such as... Figure 5As shown, the electronic device 2000 includes a memory 2200 and a processor 2400 electrically connected to the memory 2200. The memory 2200 stores a computer program that can be run on the processor 2400.
