Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of data processing, and particularly relates to a method and device for identifying power failure of a customer's area and a storage medium. BACKGROUND

[0002] The networking of the access side of the special circuit in the existing network mainly includes two scenarios: one is to deploy an optical receiver in the customer's computer room, and the customer's local area network is connected to the transmission network element through the optical receiver, the transmission network element is the terminal device for circuit scheduling when the special line is opened, and is deployed in the mobile computer room, which has power supporting monitoring capability. The other is to deploy a transmission network element in the customer's computer room, and the customer's local area network is connected to the transmission network through the customer's side transmission network element, which is the terminal device for circuit scheduling when the special line is opened. Since the customer's computer room does not have power supporting monitoring capability, it is impossible to identify the area power failure through the network management power failure alarm. When the group customer's area is powered off, the above two scenarios will report LOS (Loss of Signal) alarm and network element disconnection alarm respectively, and the upper layer fault management system will judge the fault as special line access optical cable interruption according to the alarm, and assign the fault work order to the front-line maintenance personnel. Since the network element disconnection alarm is caused by the area power failure, the maintenance personnel cannot handle it when they arrive at the scene, which causes the maintenance personnel to work inefficiently and wastes manpower and time cost.

[0029] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0030] First, the technical problem to be solved by the technical solution disclosed herein and the related technologies are described in detail.

[0031] The existing network topology on the leased line access side mainly includes Scenario 1 and Scenario 2. Scenario 1 involves deploying fiber optic transceivers (hereinafter referred to as optical transceivers) in the customer's room. The specific network topology is as follows: Figure 1 As shown, the customer's local area network (LAN) is connected to the transmission network elements via optical receivers. These transmission network elements include Synchronous Digital Hierarchy (SDH) and Packet Transport Network (PTN). These transmission network elements, serving as the end-point devices for circuit scheduling during leased line activation, are deployed in a mobile equipment room, which possesses power supply monitoring capabilities. Since the customer's equipment room lacks power supply monitoring capabilities, it cannot identify area power outages through network management power outage alarms. When a power outage occurs in the area where the group customer is located, the transmission network element in Scenario 1 will report a LOS alarm. The upper-level fault management system determines that the leased line access optical cable is interrupted based on the alarm name and dispatches a fault work order to frontline maintenance personnel. Because the LOS alarm is caused by an area power outage, maintenance personnel are unable to handle the situation upon arrival at the site.

[0032] For Scenario 1, the solution in related technologies is to replace ordinary optical receivers with "intelligent optical receivers" and enable network operations, administration, and maintenance (OAM) functions on the transmission network element. When a power outage occurs in the area, the "intelligent optical receiver" will transmit the detected power failure information to the transmission network element via the OAM protocol. The transmission network element will simultaneously report LOS alarms and remote equipment power failure alarms. The titles of the remote equipment power failure alarms are shown in Table 1. After receiving the alarm, the upper-layer fault management system determines that the cause of the LOS alarm is equipment power failure based on alarm association rules, and thus dispatches a fault work order to suppress the LOS alarm.

[0033] Table 1: Examples of Power Failure Alarms for Remote Devices

[0036] However, the solution in the related art needs to replace the ordinary optical receiver with a "smart optical receiver", and the source of the replacement cost is the network cost. According to the market price of 1300 yuan per unit of the "smart optical receiver" of the mainstream device manufacturer at present, if all the ordinary optical receivers corresponding to the PTN private line that does not support the differentiation of device power failure are replaced, a huge network cost needs to be spent, for example, if all the ordinary optical receivers corresponding to 11200 PTN private lines that do not support the differentiation of device power failure are replaced with "smart optical receivers", it is estimated that 1456 million yuan will be spent, and only part of the PTN and SDH devices in the existing network support OAM functions, for example, according to statistics, there are about 21,000 PTN private lines corresponding to PTN devices that do not support OAM functions in the existing network in Sichuan Province, and about 11,000 SDH private lines corresponding to SDH devices that do not support OAM functions, even if the ordinary optical receivers are replaced with "smart optical receivers", this part of the private line cannot distinguish the device power failure and cannot avoid the invalid fault work order.

[0037] Scenario two is to deploy a transmission network element in the customer room, and the customer LAN is connected to the transmission network through the customer-side transmission network element, and the customer-side transmission network element is the terminal device of the circuit scheduling when the private line is opened, as shown in Figure 2 Because the customer room does not have power supply monitoring capability, it cannot identify the district power failure through the network management power failure alarm. When the district where the group customer is located has a power failure, the transmission network element in scenario two is off the network, and the network management center (OMC) will report an off-network alarm, and the upper fault management system will judge that the private line access optical cable is interrupted according to the alarm name, and assign a fault work order to the front-line maintenance personnel. However, because the network element off-network alarm is caused by the district power failure, the maintenance personnel cannot handle it when they arrive on site.

[0038] For scenario two, there is no solution at present, which is a common problem in the nationwide group customer after-sales support line. When the district has a power failure, the upper fault management system assigns a fault work order to the front-line maintenance personnel, but the actual network does not have a fault, and the front-line maintenance personnel does not need to go to the site.

[0039] To solve the above problems, the present disclosure proposes a new scheme for identifying power failure in the area where the customer is located. Based on the private line circuit, latitude and longitude, and home broadband cell information in the existing network comprehensive resource management system, the real cause of the alarm generated by the customer side transmission network element is judged by associating the power supply alarm of the base station machine room near the customer, the power failure alarm of the equipment in the machine room, and the power failure alarm of the home broadband optical modem. If the system determines that the cause is the power failure in the area, the dispatch of the fault work order is suppressed, otherwise the fault work order is generated and sent to the front-line maintenance personnel, which can reduce the invalid work of the maintenance personnel, reduce the labor and time cost, and enable the maintenance personnel to have more time to participate in the collection of products, intelligent networking investigation and customer relationship maintenance. At the same time, compared with the application scenarios of the related art solutions, the present disclosure has a wider application scenario and lower network cost, thereby achieving cost reduction and efficiency improvement.

[0040] The present disclosure will be further described in detail below in combination with the drawings and specific embodiments.

[0041] Figure 3 An example diagram of a system for identifying power failure in the area where the customer is located according to an embodiment of the present disclosure.

[0042] As shown in Figure 3 The method for identifying power failure in the area where the customer is located according to an embodiment of the present disclosure includes the following steps:

[0043] Step 101, collect the power supply alarm of the base station machine room, the device power supply alarm, the home broadband optical modem power failure alarm, and the transmission alarm, and locate the transmission alarm in the private line circuit through the comprehensive resource management system to obtain the location information of the private line circuit.

[0044] In some embodiments of the present disclosure, the base station machine room refers to a room or building used for storing and maintaining mobile communication base station equipment. The base station machine room is usually located around the base station equipment and is used for placing wireless communication equipment, transmission equipment, power supply equipment, and related monitoring and control equipment.

[0045] In some embodiments of the present disclosure, the alarms of the base station machine room in the existing network are monitored in real time, and the power supply alarm of the base station machine room, the device power supply alarm, the home broadband optical modem power failure alarm, and the transmission alarm are collected and recorded.

[0046] In some embodiments of the present disclosure, the power supply alarm of the base station machine room is used to monitor the power supply of the base station machine room to ensure the normal operation of the equipment, including power load abnormalities, power supply interruptions, voltage fluctuations, etc.; the device power supply alarm is used to alert the abnormal power supply of the base station equipment or network equipment, including power supply failure, insufficient battery power, power supply line failure, etc.; the home broadband optical modem power failure alarm is used to alert the power failure of the home broadband optical modem equipment, which causes the interruption of home broadband service; the transmission alarm is usually used to alert the abnormality of the transmission equipment or transmission link, which may cause communication interruption or data transmission problems.

[0047] In some embodiments of the present disclosure, the integrated resource management system (CRM) supports customer relationship management, sales management, service management, device management, business statistics, etc. According to the transmission alarm in the present disclosure, the affected private line is located in combination with the private line circuit resource information in the integrated resource management system, the private line information is obtained, including the end device information of the private line circuit, and then the location information of the private line is found in combination with the customer location information in the integrated resource management system. Specifically, the longitude and latitude of the end device of the matching private line circuit are found.

[0048] In some embodiments of the present disclosure, in order to better implement the method of the present disclosure, a system for identifying the outage area of a customer is built, Figure 4 An example diagram of a system for identifying the outage area of a customer is shown as Figure 4 As shown, the system includes four modules: alarm collection, alarm positioning private line, home broadband online user number collection, and outage area identification.

[0049] In some embodiments of the present disclosure, the alarm collection module is used to collect power supporting alarms and / or device power alarms of base station machine rooms, home broadband optical modem power failure alarms, and transmission alarms. The power supporting alarms and / or device power alarms, home broadband optical modem power failure alarms are transmitted by the alarm collection module to the outage area identification module, and the transmission alarms are separately transmitted to the alarm positioning private line module. The alarm positioning private line module is used to locate the affected private line according to the transmission alarm transmitted by the alarm collection module in combination with the private line circuit resource in the resource management system, and transmit the private line information to the outage area identification module. The longitude and latitude of the private line are found by the outage area identification in combination with the private line information and the customer location information in the integrated resource management system.

[0050] Step 102, according to the location information of the private line circuit, the base station machine rooms within a preset distance range from the private line circuit are selected as target base station machine rooms, and it is checked whether at least one of the power supporting alarms and the device power alarms exists in the target base station machine rooms.

[0051] In some embodiments of the present disclosure, the preset distance range is determined according to the planning and construction specifications of the wireless base station, such as when the planning and construction specifications of the current wireless base station suggest a base station interval of 300 meters in towns and a base station interval of 500 meters in rural areas. The preset distance range can be 500 meters.

[0052] In some embodiments of the present disclosure, the location information of the private line circuit specifically includes the longitude and latitude of the private line. The preset distance range is circled with the longitude and latitude of the private line as the center, the base station machine rooms within the range are found by measuring the longitude and latitude distance, and then it is checked whether at least one of the power supporting alarms and the device power alarms exists in the machine room.

[0053] In some embodiments of the present disclosure, asFigure 4 The illustrated identification of the power failure system of the customer's area, the base station room within the preset distance range from the special line latitude and longitude is screened out by the area power failure identification module according to the latitude and longitude of the special line, and the power supply alarm of the base station room is collected by the alarm collection module. Whether the base station room within the preset distance range has a power supply alarm or a device power supply alarm is checked.

[0054] Step 103, in response to the target base station room not having at least one of the power supply alarm and the device power supply alarm, the home broadband cell to which the special line circuit belongs is obtained in combination with the home broadband cell information in the comprehensive resource management system and the location information of the special line circuit, and whether the home broadband online user number of the home broadband cell has an abnormal change is judged.

[0055] In some embodiments of the present disclosure, the home broadband online user number of the home broadband cell is also collected; a home broadband online user number abnormality judgment model is established according to the home broadband online user number; and whether the home broadband online user number of the home broadband cell has an abnormal change is judged by the home broadband online user number abnormality judgment model.

[0056] In some embodiments of the present disclosure, the method further comprises: in response to the target base station room having at least one of the power supply alarm and the device power supply alarm, generating a first derived alarm, and marking the first derived alarm with identification information.

[0057] In some embodiments of the present disclosure, if the base station room within the preset distance range does not have the power supply alarm or the device power supply alarm, it can also be directly determined that the business port interruption or the network element disconnection is not caused by the power failure of the customer's area, and a second derived alarm is generated; but due to the situation that the base station room within the preset distance range from the special line position cannot be found, the location information of the base station room is not accurately entered, the room is powered off, etc., the accuracy of identifying the power failure of the customer's area is reduced. Considering that the home broadband optical CAT can distinguish the fiber interruption and the device power failure, further analysis can be performed in combination with the home broadband cell resource information of the comprehensive resource management system and the home broadband optical CAT power failure alarm to identify whether the business port interruption / network element disconnection alarm is caused by the power failure of the customer's area.

[0058] In some embodiments of the present disclosure, as Figure 4 The illustrated identification of the power failure system of the customer's area, the base station room within the preset distance range from the special line latitude and longitude is screened out by the area power failure identification module according to the latitude and longitude of the special line, and the power supply alarm of the base station room is collected by the alarm collection module. Whether the base station room within the preset distance range has a power supply alarm or a device power supply alarm is checked.

[0059] In some embodiments of this disclosure, the home broadband online user count acquisition module is specifically used to collect the number of home broadband online users of the OLT (Optical Line Terminal) according to the statistical time granularity, such as 10 minutes. It combines the topology resource information of "ONU (Optical Network Unit)-cell-OLT" to aggregate and count the number of online users in each home broadband cell, and transmits the number of online users to the area power outage identification module. Here, both OLT and ONU are important devices in the optical fiber access network. The OLT is installed in the operator's central office or base station and is responsible for providing optical fiber access to users and forwarding the user's data traffic to the core network. The ONU is installed at the client and is used to receive optical signals and convert them into electrical signals to provide broadband access services. It can be understood as the terminal device of the optical fiber access network.

[0060] Step 104: If there are abnormal changes in the number of online users in the JiaKuan community, check whether there is a power outage alarm for the JiaKuan optical modem in the JiaKuan community.

[0061] In some embodiments of this disclosure, such as Figure 4 The power outage identification system shown can identify areas where customers are located. If there are abnormal changes in the number of online broadband users in the broadband community, the area power outage identification module will check whether there are any broadband optical modem power outage alarms in the broadband community based on the power outage alarms collected by the alarm collection module.

[0062] In some embodiments of this disclosure, the method further includes: generating a second derivative alarm when there is no abnormal change in the number of online broadband users in the home broadband community, wherein the second derivative alarm is used to warn that the power outage in the area where the customer is located is caused by the interruption of the service port or the disconnection of the network element; generating a fault work order corresponding to the second derivative alarm and dispatching the fault work order to the maintenance personnel.

[0063] Step 105: In the event of a power outage alarm for the optical modem in the home broadband community, a first derivative alarm is generated and an identification information is added to the first derivative alarm. The first derivative alarm is used to warn of service port interruption or network element disconnection due to power outage in the customer's area, and the identification information is used to suppress the dispatch of fault work orders for the first derivative alarm.

[0064] In some embodiments of this disclosure, the method further includes: generating a second derivative alarm when there is an abnormal change in the number of online broadband users in the broadband community and there is no power outage alarm for the broadband optical modem in the broadband community, wherein the second derivative alarm is used to warn that the power outage in the area where the customer is located is caused by the interruption of the service port or the disconnection of the network element; generating a fault work order corresponding to the second derivative alarm and dispatching the fault work order to the maintenance personnel.

[0065] In some embodiments of the present disclosure, the causes of the transmission alarm include fiber interruption and area power failure, the derived alarms include an "area power failure" type alarm and an "optical cable interruption" type alarm, the first derived early warning is the "area power failure" type alarm, and the second derived early warning is the "optical cable interruption" type alarm. If the system predicts the "optical cable interruption" type alarm, a fault work order is automatically generated and assigned to the first-line maintenance personnel; if the "area power failure" type alarm is predicted, the alarm is marked and the work order is inhibited from being assigned.

[0066] In summary, the embodiments provided by the present disclosure can assist in determining the real cause of the transmission network element alarm of a customer based on the private line circuit, location information and home broadband cell information in the integrated resource management system, by associating the base station room power supporting alarm near the customer, the power failure alarm of the equipment in the room and the power failure alarm of the optical modem of the home broadband cell. If it is determined that the cause is the area power failure, the generation of the fault work order is inhibited, otherwise the fault work order is generated and assigned to the first-line maintenance personnel, thereby reducing the invalid work of the maintenance personnel, saving the labor and time cost, allowing the maintenance personnel to have more time to participate in the sale of customer acquisition products, intelligent network exploration and customer maintenance, and the application scenarios are more extensive, the network cost is lower and the cost is reduced and the efficiency is increased compared to the related art solutions.

[0067] Based on Figure 3 the embodiments shown in the drawings, the system for identifying the area power failure of the customer includes an alarm collection module, an alarm positioning private line module, a home broadband online user number collection module and an area power failure identification module. Figure 5 As shown in the drawings, Figure 5 Another flowchart of a method for identifying the area power failure of the customer provided by the embodiments of the present disclosure is shown.

[0068] The method for identifying the area power failure of the customer provided by the embodiments of the present disclosure includes the following steps:

[0069] Step 201, collecting the power supporting alarm of the base station room, the equipment power alarm, the home broadband optical modem power failure alarm and the transmission alarm.

[0070] In some embodiments of the present disclosure, the alarms of the base station room in the existing network are monitored in real time, and the power supporting alarm of the base station room, the equipment power alarm, the home broadband optical modem power failure alarm and the transmission alarm are collected and recorded.

[0071] In some embodiments of the present disclosure, in order to better implement the method of the present disclosure, a system for identifying the area power failure of the customer is built, Figure 4 An example diagram of a system for identifying the area power failure of the customer is shown, as shown in the drawings, Figure 4 The system includes an alarm collection module, an alarm positioning private line module, a home broadband online user number collection module and an area power failure identification module.

The power supporting alarms and / or device power alarms and the home broadband optical CATV power-off alarms are transmitted to the district power outage identification module by the alarm collection module, and the transmission alarms are separately transmitted to the alarm positioning dedicated line module.

[0073] In step 202, it is determined whether the alarm object type of the transmission alarm.

[0074] In some embodiments of the present disclosure, the alarm object type includes a port and a network element, and the transmission alarm includes a port type alarm and a network element type alarm. Table 2 shows a port type alarm title, wherein ALM_DATA_RLOS is a data receive loss of signal (Data Receive Loss of Signal) alarm, indicating that the receiving end cannot detect a signal during data transmission, resulting in data loss or receiving error; ALM_DATA_TLOS is a data transmit loss of signal (Data Transmit Loss of Signal) alarm, indicating that the sending end cannot correctly send a signal during data transmission, resulting in data loss or sending error; and E1_LOS, LINK_LOS, etc. alarms shown in Table 2 are not explained one by one.

[0078]

[0079] In step 203, in the case that the alarm object of the transmission alarm is a port, the port and the network element where the port is located are matched with a dedicated line circuit table in the integrated resource management system to obtain a matched dedicated line circuit, and end device information of the dedicated line circuit is recorded, wherein the end of the dedicated line circuit includes a first end and a second end.

[0080] In some embodiments of the present disclosure, the end device information is used to indicate that the port and the network element where the port is located are matched with the first end / second end of the dedicated line circuit.

[0081] In some embodiments of the present disclosure, after determining the alarm object type of the transmission alarm, the method further comprises: in the case that the alarm object of the transmission alarm is a network element, matching the network element with a private line circuit table in the integrated resource management system to obtain a matched private line circuit; if the network element matches the first end device information, determining the location information of the private line circuit according to the customer location information in the first end device information, or if the network element matches the second end, determining the location information of the private line circuit according to the customer location information in the second end device information.

[0082] In some embodiments of the present disclosure, according to the alarm object information or the matching of the network element information where the alarm object is located and the private line circuit table, after locating the matched private line, the end device information of the private line circuit is recorded synchronously, and the end device information matched with the network element and the port of the alarm is reported, for example, whether the A end or the Z end of the private line circuit corresponding to the network element and the port of the alarm needs to be reported.

[0083] In some embodiments of the present disclosure, as shown in a power outage identification system for a customer located area, Figure 4 The alarm collection module transmits the transmission alarm to the alarm positioning private line module, the alarm positioning private line module locates the affected private line according to the transmission alarm transmitted by the alarm collection module in combination with the private line circuit resource in the resource management system, and transmits the private line information including the end device information of the private line circuit to the area power outage identification module.

[0084] In step 204, if the port matches the first end device information or the network element where the port is located matches the first end device information, the location information of the private line circuit is determined according to the customer location information in the first end device information.

[0085] In some embodiments of the present disclosure, if the port matches the second end or the network element where the port is located matches the second end, the location information of the private line circuit is determined according to the customer location information in the second end device information.

[0086] In some embodiments of the present disclosure, as shown in a power outage identification system for a customer located area, Figure 6 If the transmission object type is a port alarm, the "network element + port" information is matched with the private line circuit information in the integrated resource management system to obtain the matched private line information.

[0087] Specifically, if it is a port type alarm, "network element + port" is taken as a matching item to be brought into the private line circuit table to find the affected private line, if it is a network element type alarm, "network element" is taken as a matching item to be brought into the private line circuit table to find the affected private line, after locating the private line, the end device information of the private line circuit is recorded synchronously, and the end device information corresponding to the alarm network element and port is reported. For example, the end of the private line circuit includes A end and Z end, and it needs to be reported whether the alarm network element and port correspond to the A end or the Z end of the private line circuit.

[0088] In some embodiments of the present disclosure, the private line circuit table includes product example identification, end device information, etc., wherein each private line circuit has a product example identification, and detailed private line circuit information can be obtained from the integrated resource management system through the product example identification, and then the customer location information corresponding to the private line circuit end device can be obtained.

[0089] In some embodiments of the present disclosure, the latitude and longitude of the private line are found out in combination with the customer location information in the integrated resource management system, in other words, if it is the A end of the private line circuit, the latitude and longitude of the corresponding A end customer are found out, and if it is the Z end of the private line circuit, the latitude and longitude of the corresponding Z end customer are found out.

[0090] In some embodiments of the present disclosure, the district power failure identification module constructs a district power failure identification model, as shown in Figure 5 The district power failure identification model finds out the latitude and longitude of the private line in combination with the private line information and the customer location information in the integrated resource management system.

[0091] In step 205, according to the location information of the private line circuit, the base station machine room within a preset distance range from the private line circuit is selected as a target base station machine room, and it is checked whether the target base station machine room has at least one of the power supporting alarm and the device power supply alarm.

[0092] In some embodiments of the present disclosure, the method further includes: in response to the target base station machine room having at least one of the power supporting alarm and the device power supply alarm, generating a first derived alarm, and marking the first derived alarm with identification information.

[0093] In some embodiments of the present disclosure, the preset distance range is determined with reference to the planning and construction specifications of the wireless base station, for example, when the planning and construction specifications of the wireless base station in the city recommend a base station interval of 300 meters, and a base station interval of 500 meters in the countryside, the preset distance range can be 500 meters.

[0094] In some embodiments of the present disclosure, the location information of the private line circuit specifically includes the latitude and longitude of the private line, the preset distance range is circled with the latitude and longitude of the private line as the center, the base station machine room within the range is found out by measuring the latitude and longitude distance, and then it is checked whether the machine room has at least one of the power supporting alarm and the device power supply alarm.

[0095] In some embodiments of the present disclosure, the planning and construction specifications of the wireless base station are referred to, that is, the urban recommended base station interval is 300 meters, and the rural recommended base station interval is 500 meters. A 500-meter range is circled with the longitude and latitude of the private line as the center. The base station machine room in the range is found out by measuring the longitude and latitude distance. Then, it is checked whether the machine room has power supporting alarm or equipment power supply alarm.

[0096] In some embodiments of the present disclosure, as shown in FIG. 2, the slice power failure identification model circles a 500-meter range with the longitude and latitude of the private line as the center to find out the base station machine room in the coverage range. In combination with the power supporting alarm of the base station machine room collected by the alarm collection module, it is checked whether the base station machine room has power supporting alarm or equipment power supply alarm. If there is power supporting alarm or equipment power supply alarm, a first derivative alarm, that is, a slice power failure alarm, is generated to warn that the business port interruption or network element disconnection occurs due to the power failure of the slice where the customer is located. Figure 7

[0097] Step 206, in response to the target base station machine room not having at least one of the power supporting alarm and the equipment power supply alarm, the home broadband cell information in the comprehensive resource management system and the location information of the private line circuit are combined to obtain the home broadband cell to which the private line circuit belongs, and it is judged whether the number of home broadband online users of the home broadband cell has abnormal change.

[0098] In some embodiments of the present disclosure, if the base station machine room within the preset distance range does not have power supporting alarm or equipment power supply alarm, it can also be directly determined that the business port interruption or network element disconnection does not occur due to the power failure of the slice where the customer is located, and a second derivative alarm is generated. However, due to the situations that the base station machine room within the preset distance range from the private line position cannot be found, the location information of the base station machine room is not accurately entered, and the machine room is powered off, the accuracy of identifying the power failure of the slice where the customer is located is reduced. Considering that the home broadband optical modem can distinguish fiber interruption and equipment power failure, the home broadband cell resource information in the comprehensive resource management system and the home broadband optical modem power failure alarm can be further combined for analysis to identify whether the business port interruption / network element disconnection alarm is caused by the power failure of the slice where the customer is located.

[0099] In some embodiments of the present disclosure, the number of home broadband online users may not be judged whether there is abnormal change, and only whether the home broadband optical modem power failure alarm exists in the home broadband cell is judged to determine that the business port interruption or network element disconnection occurs due to the power failure of the slice where the customer is located, and a second derivative alarm is generated. However, due to the situation that the customer unplugs the home broadband optical modem, the home broadband optical modem power failure alarm will also be issued in this situation. Only relying on whether the home broadband optical modem power failure alarm exists in the home broadband cell reduces the accuracy of identifying the power failure of the slice where the customer is located. Therefore, the home broadband cell in which the number of online users has abnormal change needs to be located first to avoid misjudgment.

[0100] ​Step 207, if the number of home broadband online users in the home broadband cell has an abnormal change, check whether the home broadband optical CATON in the home broadband cell has a power-off alarm.

[0101] In some embodiments of the present disclosure, in the case that the number of home broadband online users in the home broadband cell has no abnormal change, a second derivative alarm is generated, wherein the second derivative alarm is used to warn that the non-customer area power failure causes service port interruption or network element disconnection; a fault work order corresponding to the second derivative alarm is generated, and the fault work order is distributed to the maintenance personnel.

[0102] Step 208, in the case that the home broadband optical CATON in the home broadband cell has a power-off alarm, a first derivative alarm is generated, and the first derivative alarm is marked with identification information, wherein the first derivative alarm is used to warn that the customer area power failure causes service port interruption or network element disconnection, and the identification information is used to suppress the distribution of the fault work order for the first derivative alarm.

[0103] In some embodiments of the present disclosure, in the case that the number of home broadband online users in the home broadband cell has an abnormal change and the home broadband optical CATON in the home broadband cell has no power-off alarm, a second derivative alarm is generated, wherein the second derivative alarm is used to warn that the non-customer area power failure causes service port interruption or network element disconnection; a fault work order corresponding to the second derivative alarm is generated, and the fault work order is distributed to the maintenance personnel.

[0104] In some embodiments of the present disclosure, the causes of the transmission alarm usually include fiber interruption and area power failure, and the derivative alarm includes “area power failure” type alarm and “optical cable interruption” type alarm, the first derivative pre-alarm is “area power failure” type alarm, and the second derivative pre-alarm is “optical cable interruption” type alarm. If the system predicts “optical cable interruption” type alarm, a fault work order is automatically generated and distributed to the first-line maintenance personnel; if it is predicted to be “area power failure” type alarm, the alarm is marked to suppress the distribution of the work order.

[0105] In some embodiments of the present disclosure, the alarm types of the derivative alarm are divided into port alarm and network element alarm based on the alarm object, as shown in Table 4, the derivative alarm title includes service port interruption, service port interruption (area power failure), disconnection alarm affecting private line, and disconnection alarm affecting private line (area power failure), wherein the “area power failure” type alarm is marked, that is, the “area power failure” is marked, to suppress the distribution of the work order.

[0106] Table 4: Derivative alarm title

[0107]

[0108] In some embodiments of the present disclosure, as shown in Figure 7As shown, according to the location information of the private line circuit, the home broadband cell covered by the private line is found out, and whether an abnormality occurs is determined according to the change of the number of online users in the home broadband cell. If an abnormality occurs, it is further checked whether there is a home broadband ONU power-off alarm. If there is an alarm, a "district power failure" alarm is generated, otherwise a "optical cable interruption" alarm is generated, otherwise a "optical cable interruption" alarm is generated.

[0109] In some embodiments of the present disclosure, as shown in Figure 8 As shown, determining whether the number of home broadband online users in the home broadband cell has an abnormal change includes the following steps 301-304:

[0110] Step 301: Collect the number of home broadband online users in the home broadband cell every preset time, and perform probability distribution verification processing on the collected number of home broadband online users to obtain the distribution rule of the number of home broadband online users.

[0111] Step 302: In the case of normal distribution of the number of home broadband online users, the observation value range of the number of home broadband online users is determined according to the mean and standard deviation of the number of home broadband online users.

[0112] In some embodiments of the present disclosure, the number of home broadband online users in a certain home broadband cell during a preset period is collected with a granularity of 10 minutes, and 4800 sampling values are obtained. It is found through statistics that the distribution rule of the number of home broadband online users. As shown in Figure 9 Figure 9 The distribution graph obtained by performing probability distribution verification on the 4800 home broadband online users through the SPSS data analysis model can be seen from Figure 9 It can be seen that the number of home broadband online users approximately obeys the normal distribution with a mean (μ) of 235.07 and a standard deviation (σ) of 57.939.

[0113] Further, the skewness and kurtosis verification method is used for verification, and the results shown in Table 5 are obtained, wherein the skewness value and the kurtosis value are both approximately equal to 0, and the Z-score (-0.019 / 0.035=0.54, -0.097 / 0.071=1.37) is between ±1.96. According to this, it can be considered that the number of home broadband online users satisfies the normal distribution.

[0114] Table 5: Skewness and kurtosis verification results

[0115]

[0116] In some embodiments of the present disclosure, in the case of normal distribution of the number of home broadband online users, an abnormality judgment model of the number of home broadband online users is constructed according to the mean and standard deviation of the number of home broadband online users.

[0117] ​In one implementation of this disclosure, it is assumed that the average number of online users in a broadband community over N consecutive statistical times is μ, and the standard deviation is σ. The number of online users at the (N+1)th statistical time is given. According to probability and statistics theory, the probability that "the observed value of a normally distributed random variable X falls within a range of 2 standard deviations (σ) from its mean (μ) is approximately 95%", thus it can be concluded that when the observed value of the normally distributed random variable X does not fall within this range, it is a low-probability event, i.e., the observed value is abnormal. This means that the number of online users in the broadband community at the (N+1)th statistical time is abnormal. Therefore, an abnormal online user count judgment model for broadband communities can be constructed: ) .

[0118] Step 303: Obtain the number of home broadband online users in the home broadband community at the first moment, and determine whether the number of home broadband online users at the first moment is within the observation range of the number of home broadband online users. Here, the first moment is the first collection moment after the transmission alarm occurs.

[0119] Step 304: If the number of home broadband online users at the first moment is not within the range of observed values ​​for the number of home broadband online users, it is determined that there is an abnormal change in the number of home broadband online users in the home broadband community.

[0120] In one implementation of this disclosure, upon receiving a transmission alarm and leased line information, the residential broadband cell to which the leased line belongs is determined based on resource information. Then, the number of online residential broadband users at the first data collection time after the transmission alarm occurrence is determined and recorded as follows: ,if If the distance from the mean (μ) is within 2 standard deviations (σ), then the abnormal number of broadband online users is satisfied by the model for judging abnormalities. ) If this is the case, it is considered that the number of online users in this broadband community is changing abnormally, and the power outage alarm reporting situation of the broadband optical modem can be further investigated.

[0121] In some embodiments of this disclosure, the method further includes: if the number of home broadband online users at the first moment is within the observed value range of the number of home broadband online users, it is determined that there is no abnormal change in the number of home broadband online users in the home broadband cell.

[0122] In some embodiments of this disclosure, the area power outage identification model proposed in this disclosure is deployed on the above-mentioned Figure 1 and Figure 2 The leased line networking scenarios shown include Scenario 1 and Scenario 2, and the deployment methods are as follows: Figure 10 and Figure 11 As shown, Figure 10 This diagram illustrates an example of deploying a regional power outage identification model in scenario one. Figure 11 The diagram shows an example of deploying a regional power outage identification model in Scenario 2.

[0123] In actual application, the slice area identification model is deployed in the designated regional leased line service according to the deployment mode shown in Figure 10 , and 6027 regional power outages in the designated regional leased line service are counted in 20 days. The system predicts that the alarm cause is a regional power outage. On-site verification of the system prediction result shows that the correlation degree of the regional power outage is more than 85%. The slice area identification model is deployed in the designated regional leased line service according to the deployment mode shown in Figure 11 , and 272 regional power outages in the designated regional leased line service are counted in 20 days. The system predicts that the alarm cause is a regional power outage. On-site verification of the system prediction result shows that the correlation degree of the regional power outage is more than 90%.

[0124] In summary, the scheme provided by the present disclosure has the following improvements and beneficial effects:

[0125] 1. The present disclosure is based on leased line circuit, latitude and longitude, and home broadband cell resource information. Whether a group customer is in a power outage area is determined by cross-professional alarm correlation assistance. The transmission alarm true cause is predicted. Compared with related technologies, the ordinary optical receiver does not need to be replaced by an "intelligent optical receiver" at the network cost, and is not limited by the type of transmission network element. All SDH, PTN, and OTN transmission network elements in the existing network are applicable. The technical means is completely used to solve the pain points in real production, and cost reduction and efficiency improvement are realized.

[0126] 2. The present disclosure proposes a method for determining abnormal changes in the number of online users in a home broadband cell, which improves the accuracy of identifying the power outage area of a customer. At the same time, the system can monitor the abnormal situation of the number of online users in the home broadband cell and be applied to other product services.

[0127] 3. The present disclosure identifies the power outage system and method of the customer's area. The product can be included in the "leased line +" product list of the front-end government and enterprise department. After the group customer subscribes to the product, when the area where the customer is located is powered off, the operator can actively push the power-off information to the customer, and selectively provide power generation and other emergency protection according to the customer's needs. It has a wide application prospect and promotional value.
