Fig. 1 is a flowchart of a fault location method across multiple network slices in an embodiment of the present invention, as shown in fig. 1, the method includes:
102, associating alarm information of a plurality of network devices in each sub-network slice of each network slice according to a preset alarm association condition, and adding the network devices with faults in the sub-network slice to a first fault device set corresponding to the network slice;
103, performing fault merging processing on the network equipment with faults in the first fault equipment set corresponding to each network slice, and updating the first fault equipment set corresponding to each network slice;
and 104, performing fault merging processing on the network equipment with faults in the first fault equipment set corresponding to each updated network slice to obtain a second fault equipment set, wherein the second fault equipment set comprises all the network equipment with faults across a plurality of network slices.
In the embodiment of the invention, not only the network equipment with faults in each sub-network slice of each network slice is considered, the network equipment with faults is subjected to two times of fault merging processing, the network equipment with faults in each network slice is subjected to the fault merging processing for the first time, and the repetition of fault positioning in each network slice is avoided; and the second time, the fault merging processing is carried out on the network equipment with the fault and spanning a plurality of network slices, namely, the relation among the network equipment with the fault and spanning a plurality of network slices is considered, so that the repeat of fault positioning in the whole network is avoided, and the accuracy of fault positioning is improved.
In step 101, a network slice is a networking-on-demand manner, and an operator can separate a plurality of virtual end-to-end networks on a unified infrastructure, and each network slice is logically isolated from a radio access network bearer network to a core network to adapt to various types of applications. NFV (network function virtualization) which is the core of the network slicing technology, wherein the NFV separates hardware and software parts from a traditional network, the hardware is deployed by a uniform server, and the software is born by different Network Functions (NF), so that the requirement of flexibly assembling services is met. The network slice comprises a plurality of sub-network slices, each sub-network slice also comprises a plurality of network devices, and the network devices can be network elements or links, collect alarm information of the network devices, and can be collected and collected uniformly by various collectors.
In an embodiment, the network slices include a wireless network slice, a bearer network slice, and a core network slice;
the sub-network slices include a wireless network sub-slice, a bearer network sub-slice, and a core network sub-slice.
In step 102, for each sub-network slice of each network slice, associating the alarm information of the plurality of network devices in the sub-network slice according to a preset alarm association condition, and adding the network device with the fault in the sub-network slice to the first faulty device set corresponding to the network slice, where the specific process is as follows:
(1) sub-network slice being wireless network sub-slice
The wireless network sub-slice mainly relates to a base station, and is subdivided into: the RRU and BBU are mainly included in the 4G network, and the AAU, DU and CU are mainly included in the 5G network.
The preset alarm association condition of the wireless network sub-slice can be read from a configuration file of the preset wireless network sub-slice without modifying a program code each time, alarm information of a plurality of network devices in the sub-network slice is associated according to the preset alarm association condition, an abnormal area, namely a network device with a fault, can be determined, and then the network device with the fault is added to a first fault device set corresponding to the network slice, wherein each network slice corresponds to one first fault device set. Besides preset alarm correlation conditions, the method can also comprise a pre-configured automatic diagnosis method, can obtain the network equipment with the fault, and can also automatically analyze the reason of the fault, thereby being beneficial to the subsequent fault location of the network equipment related to the network equipment with the fault. For example, since the base station is often shared by multiple network slices or network sub-slices, it is often easier to locate a problem after determining a faulty network device and comparing it with other wireless network sub-slice abnormal areas in a later step.
(2) The sub-network slice is a carrier network slice
The main use of the carrier net sub-slice is IPRAN, which is subdivided into: a device, B device, ER device, etc.
The preset alarm association condition of the bearer network sub-slice can be read from a configuration file of the pre-configured bearer network sub-slice, alarm information of a plurality of network devices in the bearer network sub-slice is associated according to the preset alarm association condition, and the network device with a fault in the bearer network sub-slice is added to a first fault device set corresponding to the network slice. In addition, in the initial stage of the 4G network and the 5G network, the hardware resources shared by each bearer network sub-slice are more, although the 5G network uses more technologies: technologies such as FLEX-E realize the differentiation on the time slot, but the same network element is shared, and because of the technical limitation, the NFV technology cannot be used to realize the related network element of virtualization, so that the network device with the fault is determined, and the multi-slice association positioning in the following step can be played. Similarly, in addition to the preset alarm correlation condition of the bearer network sub-slice, the method can also include a pre-configured automatic diagnosis method of the bearer network sub-slice, so that the network equipment with the fault can be obtained, the cause of the fault can be automatically analyzed, and the subsequent fault location of the network equipment related to the network equipment with the fault is facilitated.
(3) The sub-network slice is a core network sub-slice
The core network sub-slice, due to the application of NFV virtualization technology, the virtualized resources used at the bottom layer include the HOST layer of the physical machine, the VM layer of the virtual machine above, and the VNF layer of the virtualized network element above the VM, and fig. 2 is a schematic diagram of the core network sub-slice in the embodiment of the present invention, and the alarm association for the core network sub-slice is greatly different from the traditional hardware entity network element, and the radio network sub-slice and the bearer network sub-slice.
In a core network sub-slice, firstly associating layer by layer according to a preset alarm association condition, that is, firstly associating alarm information of network equipment on a HOST layer of a physical machine, then associating alarm information of network equipment on a VM layer of a virtual machine, and finally associating alarm information on a VNF layer of a virtualized network element, so as to form a three-layer association topology, where fig. 3 is a schematic diagram of the three-layer association topology of the core network sub-slice formed in the embodiment of the present invention, and according to the three-layer association topology, a network equipment with a fault in the core network sub-slice is determined and added to a first fault equipment set corresponding to the network slice, and accuracy of fault location in the core network sub-slice can be improved through the three-layer association topology.
In an embodiment, before performing the failure merging process on the network devices having failures in the first set of failed devices corresponding to each network slice, the method further includes:
performing alarm association on the network equipment with faults spanning multiple wireless network sub-slices in each network slice, and deleting repeated network equipment from a first fault equipment set corresponding to the network slice according to an alarm association result;
performing alarm association on the network equipment with faults in each network slice spanning multiple bearing network sub-slices, and deleting repeated network equipment from a first fault equipment set corresponding to the network slice according to an alarm association result;
and performing alarm association on the network equipment with faults in each network slice spanning multiple core network sub-slices, and deleting repeated network equipment from a first fault equipment set corresponding to the network slice according to an alarm association result.
In the above embodiment, part of repeated network devices with faults are deleted, workload of merging subsequent faults is reduced, and work efficiency is improved, taking a network device with faults across two wireless network sub-slices as an example, a wireless network sub-slice 1 includes a base station 1, and a wireless network sub-slice 2 also includes a base station 1, so if a fault exists in the base station 1, two times are recorded in a first faulty device set, and at this time, one base station needs to be deleted.
In specific implementation, there are various methods for performing fault merging processing on the network devices having faults in the first faulty device set corresponding to each network slice and updating the first faulty device set corresponding to each network slice, and one of the embodiments is given below.
In an embodiment, performing fault merging processing on a network device having a fault in a first faulty device set corresponding to each network slice, and updating the first faulty device set corresponding to each network slice includes:
for each network slice, if the faults of a plurality of network devices with faults in a plurality of wireless network sub-slices are caused by a plurality of network devices in a carrier network sub-slice of the network slice, adding the plurality of network devices in the carrier network sub-slice to a first fault device set corresponding to the network slice, and deleting the plurality of network devices with faults in the plurality of wireless network sub-slices from the first fault device set corresponding to the network slice;
for each network slice, if the faults of a plurality of network devices with faults in a plurality of bearer network sub-slices are caused by a plurality of network devices in a core network sub-slice of the network slice, adding the plurality of network devices in the core network sub-slice to a first fault device set corresponding to the network slice, and deleting the plurality of network devices with faults in the plurality of bearer network sub-slices from the first fault device set corresponding to the network slice.
In the foregoing embodiment, a network device that really has a fault can be accurately determined, and accuracy of fault location is improved, for example, one network slice includes 3 radio network sub-slices, 2 bearer network sub-slices, and 1 core network sub-slice, where the 3 radio network sub-slices respectively include a base station 1, a base station 2, and a base station 3 that have a fault, and all three base stations belong to the same a device management in the 1 bearer network sub-slice, so that it is possible that the a device in the bearer network sub-slice has a fault instead of the faults of the three base stations, at this time, the a device needs to be added to the first faulty device set, and the three base stations are deleted from the first faulty device set. As another example, in the above example, if base station 1, base station 2, and base station 3 belong to different a device management systems, and the a devices are all associated with the same B device, it may be that there is a failure in the B device in this bearer network sub-slice, then add the B device to the first failed device set, and delete three base stations from the first failed device set. Based on the same principle, if the plurality of devices with faults exist in the carrier network sub-slice, the devices can be analyzed to the network devices in the core network sub-slice, so that only the operation and maintenance personnel of the core network sub-slice need to process the devices, and the operation and maintenance personnel of the wireless network sub-slice and the carrier network sub-slice do not need to process the faults, thereby saving the working cost of the devices and improving the working efficiency.
All the above are performed by analyzing sub-network slices within the same network slice, and there is a relationship between multiple network slices.
In an embodiment, before performing the failure merging process on the network device having the failure in the first failed device set corresponding to each updated network slice, the method further includes:
merging the first failure equipment sets corresponding to all the network slices to obtain a second failure equipment set;
performing alarm association on the network equipment which has faults and spans a plurality of wireless network slices, and deleting repeated network equipment from the second fault equipment set;
alarm association is carried out on the network equipment which has faults and spans a plurality of bearing network slices, and repeated network equipment is deleted from the second fault equipment set;
and performing alarm association on the network equipment with faults spanning the plurality of core network slices, and deleting repeated network equipment from the second fault equipment set.
In the above embodiment, part of repeated network devices with faults in the first faulty device set are deleted, workload of merging subsequent faults is reduced, and work efficiency is improved, taking a network device with faults across two wireless network slices as an example, the wireless network slice 1 includes the base station 5, and the wireless network slice 2 also includes the base station 5, so if the base station 5 has faults, two times are recorded in the second faulty device set, and at this time, one base station needs to be deleted.
In specific implementation, there are various methods for performing fault merging processing on the network devices having faults in the first faulty device set corresponding to each updated network slice to obtain the second faulty device set, and one embodiment is given below.
In an embodiment, performing fault merging processing on a network device with a fault in a first faulty device set corresponding to each updated network slice to obtain a second faulty device set includes:
if the faults of a plurality of network devices with faults in a plurality of wireless network slices are caused by a plurality of network devices in a bearing network slice, adding the plurality of network devices in the bearing network slice into a second fault device set, and deleting the plurality of network devices with faults in the plurality of wireless network slices from the second fault device set;
if the faults of the network devices with faults in the multiple bearer network slices are caused by the network devices in the core network slice, adding the network devices in the core network slice to a second fault device set, and deleting the network devices with faults in the multiple bearer network slices from the second fault device set.
In the embodiment, similar to the alarm correlation among the previous sub-network slices, the network slices are sequentially analyzed upwards from the wireless network slice, the bearer network slice and the core network slice, so that the network equipment with the fault really exists is more accurately positioned, the fault positioning across a plurality of network slices is realized, the root cause point of the group fault can be more effectively found, and the fault and hidden danger in the whole operation and maintenance can be more quickly solved.
Based on the above embodiments, the present invention provides the following embodiment to explain a detailed flow of the fault location method across multiple network slices, and fig. 4 is a detailed flow chart of the fault location method across multiple network slices according to the embodiment of the present invention, as shown in fig. 4, in an embodiment, the detailed flow of the fault location method across multiple network slices includes:
the network slices comprise a wireless network slice, a bearer network slice and a core network slice; the sub-network slices comprise a wireless network sub-slice, a carrier network sub-slice and a core network sub-slice;
404, performing alarm association on the network equipment with faults spanning multiple carrier network sub-slices in each network slice, and deleting repeated network equipment from a first fault equipment set corresponding to the network slice according to an alarm association result;
