[0048] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0049] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0051] This application provides a fault handling method and apparatus, a cloud platform, and a processor-readable storage medium to solve the problem of low resource utilization of physical host machines in the prior art.

[0052] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0053] To facilitate understanding of the fault handling method in this embodiment of the invention, the following content will be introduced first:

[0054] like Figure 1 As shown, Figure 1 This is a network diagram illustrating a smart transport network (STN) according to an embodiment of the present invention. The smart transport network includes several base stations, which can be of different types; for example, base stations can include 3G base stations, 4G base stations, and 5G base stations. The smart transport network also includes several routing devices communicatively connected to the base stations, and a core network communicatively connected to the routing devices. Communication between the base stations and the core network can be achieved through the routing devices.

[0055] In practical implementations, routing devices can include access devices (STN-A), aggregation devices (STN-B), and core devices (STN-ER). Depending on their hierarchical position within the intelligent transport network, different routing devices can carry different levels of data. For example, a core device at the metropolitan area network (MAN) level can be a MAN core device, while a core device at the provincial capital network (GVCU) level can be a GVCU aggregation core device.

[0056] Specifically, the intelligent transport network uses a 5G network to simultaneously carry 3G, 4G, and 5G base stations. Specifically, each 3G, 4G, and 5G base station can connect to at least one base station access device (STN-A). The base station access device can connect to a base station aggregation device (STN-B) via two primary and backup pseudowires (PW). The base station aggregation device can act as a three-layer gateway for the 3G, 4G, and 5G base stations, terminating the primary and backup pseudowires, and integrating the gateways of the 3G, 4G, and 5G base stations into the 3G-RAN network, the gateways of the 4G base stations into the CDMA-RAN network, and the gateways of the 5G base stations into the 5G-RAN VPN network.

[0057] To simultaneously meet the IPv4 address requirements of 3G and 4G base stations and the IPv6 address requirements of 5G base stations, IPv4 single stack can be enabled in 3G-RAN and CDMA-RAN networks, and IPv6 single stack can be enabled in 5G-RAN VPN networks. The base station aggregation equipment (STN-B) and its upstream equipment, such as the metropolitan area network core equipment (STN-ER) and the provincial capital aggregation core equipment (STN-ER), can deploy a Layer 3 VPN technology (L3VPN) using Multiprotocol Label Switching (MPLS), and simultaneously deploy a Layer 3 VPN technology (L3VPN) using the Segment Routing (SRv6) protocol based on the IPv6 forwarding plane. This transmits 3G network traffic to the Multi-VPN-Instance Customer Edge (MCE) and further uploads it to the CDMA core network in the backbone network. 4G network traffic is transmitted through the provincial capital aggregation IP transport network core equipment (IPRAN-ER) to the Evolved Packet Core Customer Edge (EPC-CE) and further uploads it to the Evolved Packet Core (EPC) in the backbone network. 5G network traffic is transmitted to the 5G Core Network Customer Edge (5G Core Network Customer Edge). Edge (5GC-CE) and further uploaded to the 5G core network in the backbone network.

[0058] Reference Figure 2 The diagram illustrates a flowchart of a fault handling method provided in an embodiment of the present invention. This method is applied to an intelligent transmission network, which includes several base stations, several routing devices communicatively connected to the base stations, and a core network communicatively connected to the routing devices. Specifically, the method may include the following steps:

[0059] Step 201: In the event of a failure in the intelligent transmission network, receive a query request from maintenance personnel;

[0060] Generally, to facilitate the management of intelligent transmission networks, a management system can be set up for maintenance personnel. This system can be used to view the operational status of the intelligent transmission network and, in the event of a malfunction, provide maintenance personnel with relevant fault information.

[0061] Therefore, in the event of a fault in the intelligent transmission network, maintenance personnel can send a query request to the management system in order to promptly identify the equipment affected by the fault within the intelligent transmission network.

[0062] Step 202: Based on the query request, collect device activity information in the intelligent transmission network during a preset historical time period;

[0063] After receiving a query request, the management system can collect activity information of each device in the smart transmission network during a preset historical period to determine whether any device is in a state of malfunction.

[0064] Step 203: Extract device information that is in a fault state or offline state from the device activity information;

[0065] Generally, if there are devices in a smart transmission network that are not in normal working order, they can usually be in a fault state (down state) or offline state. Therefore, the device information in the fault state or offline state can be extracted from the device activity information so that the affected devices in the smart transmission network can be further identified based on the device information in the fault state or offline state.

[0066] Step 204: Based on the device information in a faulty or offline state and the preset intelligent transmission network topology information, determine the topology information of the faulty device in the intelligent transmission network and report it to the maintenance personnel.

[0067] In practice, devices in a faulty or offline state can typically affect their downstream devices. For example, if a base station aggregation device (STN-B) is faulty, its downstream base station access device (STN-A) or base station may be affected and unable to function properly. However, since the base station access device (STN-A) can usually be connected to two base station aggregation devices (STN-B) via pseudowires, its downstream base station access device (STN-A) can communicate through other base station aggregation devices (STN-B), thus allowing the base station access device (STN-A) or base station to remain operational.

[0068] Therefore, based on the information of devices in a faulty or offline state and the preset intelligent transmission network topology, the operating status of each device in the intelligent transmission network can be analyzed. This allows for the identification of other devices affected by the faulty or offline devices, and ultimately, the topology information of the faulty devices in the intelligent transmission network can be determined. Based on this topology information, the information of devices in the intelligent transmission network that cannot be used normally can be identified. Feeding this faulty topology information back to maintenance personnel facilitates prompt maintenance of the intelligent transmission network.

[0069] In the specific implementation, refer to Figure 1 The network diagram of the intelligent transport network shown illustrates a dual uplink network structure from the base station access device (STN-A) to the base station aggregation device (STN-B). The uplink between the base station aggregation device (STN-B) and the metropolitan area network core device (STN-ER) can adopt a cross-connect network structure. Therefore, if a single network element above the base station aggregation device (STN-B) fails, it will not adversely affect the base station. However, if a pair of base station aggregation devices (STN-B) or a pair of metropolitan area network core devices (STN-ER) fail, it can cause the base station access device (STN-A) network element to generate a network disconnection alarm, in which case the base station can be affected.

[0070] The base station access device (STN-A) can be ring-connected to the base station aggregation device (STN-B). If the uplink port of the base station access device (STN-A) fails, ring protection can prevent the base station from being affected. However, if both uplink ports of the base station access device (STN-A) fail, it can cause the STN-A network element to generate a network disconnection alarm, in which case the base station can be affected. Similarly, if the STN-A has a downlink port failure, the base station can also be affected. Therefore, device activity information can include device fault alarms (down alarms) or network disconnection alarms. Generally, fault alarms or network disconnection alarms are issued by the base station access device (STN-A). This allows for analysis of the operating status of each device in the intelligent transport network, identifying other devices affected by devices in a faulty or disconnected state, and ultimately determining the topology information of the faulty devices in the intelligent transport network.

[0071] The fault handling method provided by this invention receives a query request from maintenance personnel when a fault occurs in the intelligent transmission network; based on the query request, it collects equipment activity information in the intelligent transmission network within a preset historical time period; it extracts equipment information in a faulty or offline state from the equipment activity information; and based on the equipment information in a faulty or offline state and preset intelligent transmission network networking information, it determines the topology information of the faulty equipment in the intelligent transmission network and feeds it back to the maintenance personnel. This method can efficiently determine the topology information of the faulty equipment and shorten the fault handling time.

[0072] Specifically, in this embodiment of the invention, the routing device includes a base station access device and a base station aggregation device. As a specific example of the invention, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of a network structure from a base station to a base station gateway according to an embodiment of the present invention. The base station and the base station access device are physically connected, and the base station access device establishes a point-to-point primary / backup connection with two base station aggregation devices via pseudowires. Furthermore, the primary pseudowire and the backup pseudowire can be identified separately using different identification information (VCID, Virtual Circuit Identifier).

[0073] If several services under a base station need to connect to the base station access device through a single physical interface, the physical interface can be divided into several sub-interfaces to connect with the base station access device using the VLAN (Virtual Local Area Network) protocol.

[0074] Generally, base station access devices can communicate with base station aggregation devices via physical or logical interconnection. A Layer 2 VPN (L2VPN) using Multiprotocol Label Switching (MPLS) technology can be established between the base station aggregation device and the base station access device. In this case, since the base station aggregation device cannot connect to the base station access device using a one-to-one physical interface, it can establish separate Layer 2 virtual interfaces based on the number of base station types, thereby isolating different types of base station networks. This allows for the isolation of base station networks from 3G, 4G, and 5G base stations.

[0075] In addition, the base station aggregation equipment can establish different Layer 3 VPN technologies (L3VPN) using Multiprotocol Label Switching (MPLS) according to the differences in base station types, and make the Layer 3 virtual interface correspond one-to-one with the Layer 2 virtual interface, thereby binding different types of Layer 3 VPNs using MPLS to the corresponding Layer 3 virtual interface.

[0076] Meanwhile, the base station aggregation device can also bridge the Layer 2 virtual interface and the Layer 3 virtual interface, and configure the base station gateway under the Layer 3 virtual interface. The base station aggregation device will terminate the pseudowire into the Layer 3 VPN using the Multiprotocol Label Switching protocol.

[0077] In this scenario, if base station addresses are sufficient, IPv4 and IPv6 can use 30 and 127 subnet masks respectively, such as "255.255.255.252" and "FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFE". The first available network address is assigned to the base station, and the second available network address is assigned as the base station's gateway to the base station aggregation device.

[0078] Alternatively, the base station access device can be used as the gateway of the base station, and the gateway address of the base station can be assigned to the base station access device.

[0079] Reference Figure 4 The diagram illustrates a flowchart of a fault handling method provided in an embodiment of the present invention. This method is applied to an intelligent transmission network, which includes several base stations, several routing devices communicatively connected to the base stations, and a core network communicatively connected to the routing devices. Specifically, the method may include the following steps:

[0080] Step 401: In the event of a failure in the intelligent transmission network, receive a query request from maintenance personnel;

[0081] Generally, to facilitate the management of intelligent transmission networks, a management system can be set up for maintenance personnel. This system can be used to view the operational status of the intelligent transmission network and, in the event of a malfunction, provide maintenance personnel with relevant fault information.

[0082] Therefore, in the event of a fault in the intelligent transmission network, maintenance personnel can send a query request to the management system in order to promptly identify the equipment affected by the fault within the intelligent transmission network.

[0083] Step 402: Based on the query request, collect device activity information in the intelligent transmission network during a preset historical time period;

[0084] After receiving a query request, the management system can collect activity information of each device in the intelligent transmission network within a preset historical time period to determine whether any devices are in a state of malfunction. The preset historical time period can be determined according to actual needs, such as device activity information within the past 10 minutes, the past hour, or the past day; this invention does not impose any limitations on this.

[0085] Step 403: Extract device information that is in a fault state or offline state from the device activity information;

[0086] Generally, if there are devices in a smart transmission network that are not in normal working order, they can usually be in a fault state (down state) or offline state. Therefore, the device information in the fault state or offline state can be extracted from the device activity information so that the affected devices in the smart transmission network can be further identified based on the device information in the fault state or offline state.

[0087] Step 404: Based on the device information in the fault state or offline state and the preset intelligent transmission network networking information, find the virtual interface information associated with the device information in the fault state or offline state.

[0088] In practice, devices in a faulty or offline state can typically affect their downstream devices. For example, if a base station aggregation device (STN-B) is faulty, its downstream base station access device (STN-A) or base station may be affected and unable to function properly. However, since the base station access device (STN-A) can usually be connected to two base station aggregation devices (STN-B) via pseudowires, its downstream base station access device (STN-A) can communicate through other base station aggregation devices (STN-B), thus allowing the base station access device (STN-A) or base station to remain operational.

[0089] Furthermore, since the intelligent transmission network in this embodiment of the invention uses L3VPN technology, devices in a faulty or offline state can have virtual interfaces. Other devices connected to this device, such as base stations, can connect through virtual interfaces instead of directly connecting to the device's physical interface. Therefore, to further determine other devices affected by the malfunctioning device, it is necessary to find the virtual interface information associated with the device information in the faulty or offline state.

[0090] In practical implementation, since devices in a faulty or offline state are typically base station access devices, the associated base station aggregation device can be determined based on the port information of the base station access device, and the virtual interface information of the base station aggregation device can be obtained. Specifically, this virtual interface information can be the interface information of the Layer 3 virtual interface of the base station aggregation device.

[0091] Step 405: Based on the virtual interface information and the intelligent transmission network topology information, determine the topology information of the faulty equipment in the intelligent transmission network and report it to the maintenance personnel.

[0092] Subsequently, based on the virtual interface information, the operational status of each device in the intelligent transmission network can be analyzed to identify other devices affected by those in a faulty or offline state. Finally, the topology information of the faulty devices in the intelligent transmission network can be determined. Based on this topology information, the information of devices in the intelligent transmission network that cannot be used normally can be identified. Feeding this topology information to maintenance personnel facilitates prompt maintenance of the intelligent transmission network.

[0093] In one embodiment of the present invention, the step of determining the topology information of faulty devices in the intelligent transmission network and feeding it back to maintenance personnel based on the virtual interface information and the intelligent transmission network topology information includes:

[0094] S11, Determine the base station gateway address based on the virtual interface information;

[0095] Specifically, since the base station aggregation equipment is configured with a base station gateway under the Layer 3 virtual interface, the base station gateway address associated with the virtual interface information can be directly determined after the virtual interface information is determined.

[0096] Alternatively, if the base station gateway is assigned to the base station access device, the gateway address of the base station can be found directly based on the information of the base station access device that is in a faulty or offline state.

[0097] S12, Calculate the base station address corresponding to the base station gateway address;

[0098] Subsequently, since the base station gateway address and the base station address are associated, the base station address can be directly calculated based on the base station gateway address.

[0099] In practice, the base station address can be calculated by subtracting 1 from the last bit of the base station gateway address.

[0100] S13. Based on the virtual interface information, the base station gateway address, the base station address, and the intelligent transmission network networking information, determine the topology information of the faulty equipment in the intelligent transmission network and report it to the maintenance personnel.

[0101] Once the virtual interface information, base station gateway address, and base station address are obtained, the base stations and base station aggregation devices associated with the base station access devices that are offline or in a faulty state can be obtained. Subsequently, based on the intelligent transmission network topology information, it can be determined whether the base stations and base station aggregation devices associated with the base station access devices that are offline or in a faulty state are affected. Finally, the topology information of the faulty devices in the intelligent transmission network can be determined and reported to the maintenance personnel.

[0102] In one embodiment of the present invention, the method further includes: the method further includes:

[0103] S21, Based on the faulty device topology information, generate a visualized faulty device topology map;

[0104] Specifically, to facilitate the maintenance of topology information, a visualized topology diagram of the faulty devices can be generated based on the topology information of the faulty devices.

[0105] S22, The topology diagram of the faulty equipment is shown to the maintenance personnel.

[0106] Subsequently, the topology diagram of the faulty equipment can be shown to the maintenance personnel, enabling them to intuitively determine the cause of the intelligent transmission network failure based on the diagram and perform timely maintenance.

[0107] As a specific example of the present invention Figure 5 This is a flowchart illustrating a fault handling method according to an embodiment of the present invention. When a base station access device malfunctions, the port information of the base station access device is first obtained, and it is determined whether the current base station gateway is located on the base station access device or the base station aggregation device. If it is on the base station access device, the associated base station gateway address can be directly found based on the port information of the base station access device, and the base station address is calculated based on the base station gateway address. If the base station gateway is located on the base station aggregation device, the pseudowire identification information can be found based on the port information of the base station access device. Based on the network information of the intelligent transmission network and the pseudowire identification information, the Layer 2 virtual interface information of the base station aggregation device bound to the pseudowire identification information is found. Subsequently, based on the correspondence between the Layer 2 and Layer 3 virtual interfaces of the base station aggregation device, the Layer 3 virtual interface information is found, and the base station gateway address bound to the Layer 3 virtual interface information is further determined. The base station address is calculated based on the base station gateway address. Finally, based on the virtual interface information of the second device, the base station gateway address, the base station address, and the network information of the intelligent transmission network, the topology information of the faulty device is determined.

[0108] The above describes the fault handling method provided by the embodiments of the present invention. The fault handling device provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.
