[0035] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0036] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no special meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0037] Figure 1 is a first flow chart of a fault detection method provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include the following steps:

[0038] Step S101: Acquire ARP (Address Resolution Protocol, a TCP / IP protocol for acquiring a physical address based on an IP address) information of a Layer 3 VPN base station service and relationship information between a base station and a remote controller.

[0039] The ARP information of the three-layer VPN base station service includes a specified date ARP information set and a current date ARP information set based on the same time point of the three-layer VPN base station service. For example, the specified date ARP information set is a set of ARP information collected at 00:00:00 of the previous day, and the current date ARP information set is a set of ARP information collected at 00:00:00 of the current day. Both the specified date ARP information set and the current date ARP information set include the VPN routing table VRF, the address of the base station, and the device name of the access device connected.

[0040] The relationship information between the base station and the remote controller includes the corresponding relationship between the address of the base station and the address of the remote controller.

[0041] Step S102: Determine the state of the ARP information according to the ARP information of the Layer 3 VPN base station service.

[0042] Step S102 may include: determining the state of the ARP information in the current date ARP information set as a normal state of the ARP information.

[0043] Step S103: locating a base station access side fault or a base station bearer side fault according to the state of the ARP information and the relationship information between the base station and the remote controller.

[0044] Specifically, if the status of the ARP information is the normal state of the ARP information, a connectivity check is performed from the access device to the base station to which it accesses and a connectivity check is performed from the access device to the remote controller associated with the base station to which it accesses. For example, a ping test is used to perform a connectivity check from the access device to the base station to which it accesses and a connectivity check from the access device to the remote controller associated with the base station to which it accesses, to determine a base station access side fault or a base station bearer side fault.

[0045] Figure 2 is a second flow chart of the fault detection method provided by an embodiment of the present invention, such as Figure 2 As shown, in Figure 1 After step S103 of the embodiment, the method may further include:

[0046] Step S104: Perform path restoration on the failed base station access side or base station bearer side, for example, by performing trace detection, performing path restoration, and determining a suspicious device on the path that causes the failure.

[0047] Through the embodiments of the present invention, from the user's perspective, by selecting a certain L3 service and performing connectivity detection, the access test failure or the bearer test failure can be quickly located, and the service path can be further restored to quickly find the problematic device; from the development perspective, the relationship between the base station address, access device, and remote controller can be dynamically collected, and an end-to-end connectivity test (such as SQA ICMP end test) can be initiated from the access device to the base station and the remote control to test the connectivity of both ends at one time. For the problematic end, a TRACE test can be initiated to find the problematic jump device.

[0048] The method provided in the embodiment of the present invention can detect a fault on the access side of a base station or a base station bearing side, or can detect a fault on the access side of a base station and a base station bearing side. Figure 1 In the illustrated embodiment, step S102 may further include: determining the difference between the ARP information set of the specified date and the ARP information set of the current date according to the ARP information set of the specified date and the ARP information set of the current date, and determining the state of the ARP information in the difference as the ARP information missing state. The ARP information missing indicates that the base station is not online, and a base station side fault can be determined. At this time, in one embodiment, the method may further include: if the state of the ARP information is the ARP information missing state, determining the base station access side fault and preliminarily determining the base station bearer side fault, and performing path restoration on the base station access side and the base station bearer side respectively, for example, by performing trace detection, performing path restoration, and determining the suspicious device on the path that causes the fault. In another embodiment, the method may further include: if the state of the ARP information is the ARP information missing state, determining the base station access side fault, and determining whether the base station bearer side is faulty through ping detection, and then performing path restoration on the faulty side, for example, by performing trace detection, performing path restoration, and determining the suspicious device on the path that causes the fault.

[0049] Figure 3 : is a schematic diagram of a flow chart of an implementation method of intelligent detection of base station service failures provided by an embodiment of the present invention, such as Figure 3 As shown, the method shown may include the following steps:

[0050] Step S301: Collect ARP information.

[0051] Collect ARP information at regular intervals, for example, at 00:00:00, collect ARP information of L3 service VPN routing chanp forwarding table 1 (vrf1), as shown in the following table.

[0052] Collection time VRF Name Device Name Base station address 2020-5-11 00:00:00 Vrf1 Device 1 1.1.1.1 2020-5-11 00:00:00 Vrf1 Device 1 1.1.1.2 2020-5-12 00:00:00 Vrf1 Device 1 1.1.1.2 2020-5-12 00:00:00 Vrf1 Device 1 1.1.1.3

[0053] The main purpose of collecting ARP information is to find the device connected to the base station. For example, the access device of base station 1.1.1.1 is device 1, which is used as the landing point for subsequent detection. Base station ARP information is collected regularly, and each collection is a collection of time bases.

[0054] Step S302: Import the relationship between the base station and the remote controller.

[0055] The relationship data between the base station and the remote controller has been determined when the base station is planned. It is static data and can be imported once by the user. Maintenance is required only when a new base station is connected or the base station is changed, and it will not have much impact on subsequent use.

[0056] The structure is shown in the following table:

[0057] Base ID Base station address Remote controller address 0 1.1.1.1 2.1.1.1 1 1.1.1.2 2.1.1.2 2 1.1.1.3 2.1.1.1 3 1.1.1.4 2.1.1.2

[0058] Step S303: Calculate the base station ARP status under vrf1.

[0059] Taking 2020-5-11 00:00:00 as the base time of ARP information, set the ARP data of 2020-5-11 00:00:00 as set A (specified date ARP information set ARP information set), and set the ARP data of 2020-5-12 00:00:00 as set B (i.e. the current date ARP information set).

[0060] The result set information is set C (the union of the ARP information set of the specified date and the ARP information set of the current date), C = A∪B, that is, the data in C is equal to the union of A and B. Figure 4 shown.

[0061] like Figure 5 As shown, the ARP status in AB is set to missing, and the ARP status in B is set to normal, including the added base station, such as base station 1.1.1.3.

[0062] The calculation results are shown in the following table:

[0063] VRF Name Device Name Base station address ARP Status Vrf1 Device 1 1.1.1.1 Missing Vrf1 Device 1 1.1.1.2 normal Vrf1 Device 2 1.1.1.3 normal

[0064] Step S304: Perform connectivity detection;

[0065] If the ARP status is missing, it means that the base station is not online, and the connectivity status is directly set to disconnected, and it will no longer participate in connectivity detection;

[0066] If the ARP status is normal, perform SQA-ICMP detection and set the status according to the actual detection result;

[0067] When the test is executed, Figure 6 As shown in the figure, the base station access device in the ARP table is used as the landing device, and detection is initiated on the base station and the remote controller at the same time. The execution results are shown in the following table:

[0068] Base station address Base station status Remote controller address Result Status 1.1.1.1 Break 2.1.1.1 Break 1.1.1.2 Pass 2.1.1.2 Pass 1.1.1.3 Pass 2.1.1.1 Break

[0069] It should be noted that SQA ICMP detection is a unique detection of ZTE. Although it is used in the same way as ordinary PING detection, it can provide more detailed performance indicators and provide a reference for the network quality on the base station side. The performance indicators it provides may include: packet loss, delay (maximum, minimum, average), jitter (maximum, minimum, average), positive jitter (maximum, minimum, average), and negative jitter (maximum, minimum, average). Ordinary PIGN detection does not support positive and negative jitter indicators.

[0070] Step S305: Path restoration to find suspicious devices.

[0071] For the end with broken connectivity, perform TRACE detection to find the problem jump address and corresponding device. Filter by base station address to find all suspicious devices and interface addresses related to this base station. The execution results are shown in the following table.

[0072] Base station address Destination Address Question jump tag Problem Jump Address Suspicious device 1.1.1.1 1.1.1.1 1 1.1.10.1 Devicex 1.1.1.2 2.1.1.1 3 PreHop: 1.1.10.2 Equipment

[0073] The TRACE detection used in actual detection only displays the jumps that failed the detection when executed in batches, and finds out the devices corresponding to the jump addresses of the jumps that failed the detection, that is, the suspicious devices; if the jumps that failed the detection have no jump addresses, the problem jump is determined to be the jump address of the jump closest to the jump that failed the detection, such as PreHop (previous jump): 1.1.10.2.

[0074] This embodiment collects L3 service ARP information regularly; imports and maintains the relationship table between the base station and the remote controller; selects a certain L3 service and calculates the ARP information related to it; verifies the connectivity of both ends according to the ARP information; performs path restoration on the end with connectivity problems to find the device with problems, and implements a one-time test of the connectivity of both ends, and initiates a TRACE test on the end with problems to find the device with problems, making fault detection simple and fast. Furthermore, the user selects the L3 service, performs connectivity detection to determine the wrong direction, and performs TRACE detection to find the device with problems. It also has the following advantages: for end-to-end services, data is automatically generated, execution is simple and fast, indicators are detailed, and goals are clear.

[0075] Figure 7is a schematic structural block diagram of a fault detection device provided by an embodiment of the present invention, such as Figure 7 As shown, the device may include an information acquisition module 10, a state determination module 20 and a fault direction location module 30, wherein:

[0076] The information acquisition module 10 is used to obtain the address resolution protocol ARP information of the three-layer VPN base station service and the relationship information between the base station and the remote controller. Among them, the ARP information of the three-layer VPN base station service includes the specified date ARP information set and the current date ARP information set of the three-layer VPN base station service based on the same time point. For example, the specified date ARP information set is a set of ARP information collected at 00:00:00 of the previous day, and the current date ARP information set is a set of ARP information collected at 00:00:00 of the current day. The specified date ARP information set and the current date ARP information set both include the VPN routing table VRF, the address of the base station, and the device name of the access device connected. The relationship information between the base station and the remote controller includes the corresponding relationship between the address of the base station and the address of the remote controller.

[0077] The state determination module 20 is used to determine the state of the ARP information according to the ARP information of the Layer 3 VPN base station service. The state determination module 20 is specifically used to determine the state of the ARP information in the ARP information set of the current date as the normal state of the ARP information.

[0078] The fault direction positioning module 30 is used to locate the base station access side fault or the base station bearer side fault according to the state of the ARP information and the relationship information between the base station and the remote controller. Specifically, if the state of the ARP information is the normal state of the ARP information, a connectivity check from the access device to the base station it accesses and a connectivity check from the access device to the remote controller associated with the base station it accesses are performed. For example, a connectivity check from the access device to the base station it accesses and a connectivity check from the access device to the remote controller associated with the base station it accesses are performed using a ping test to determine the base station access side fault or the base station bearer side fault.

[0079] The apparatus may further include a faulty device locating module 40, which is used to perform path restoration on the failed base station access side or base station bearer side, for example, by performing trace detection, performing path restoration, and determining the suspected device on the path that caused the fault.

[0080] Through the embodiment of the present invention, a certain L3 service is selected and connectivity detection is performed, so that an access test failure or a bearer test failure can be quickly located, and then the service path is further restored to quickly find the faulty device.

[0081] The device provided in the embodiment of the present invention can detect a fault on the access side of a base station or a base station bearing side, or can detect a fault on the access side of a base station and a base station bearing side. Figure 7 Based on the device embodiment, the state determination module 20 can also be used to determine the difference between the specified date ARP information set and the current date ARP information set based on the specified date ARP information set and the current date ARP information set, and determine the state of the ARP information in the difference as the ARP information missing state. Furthermore, the fault direction location module 30 can also be used to preliminarily determine that both the base station access side and the base station bearer side are faulty when the state of the ARP information is the ARP information missing state. At this time, the faulty device location module 40 can perform path restoration on the faulty base station access side and base station bearer side respectively, for example, by performing trace detection, performing path restoration, and determining the suspicious device on the path that caused the fault.
