Problems solved by technology

[0008] 4) VNF instances may send application layer faults to different correlation points, mainly EM (4.1) and VNFM (4.2)
[0009] 5) Fault correlation may occur at any fault correlation point
[0011] 7) Additional fault correlation and handling may be performed in OSS
[0013] 1) The existing network management system can only manage physical network elements or virtual network elements, and two sets of network management systems are used to manage physical network elements and virtual network elements, and the versatility is not good;
[0014] 2) NFV defines the management scheme of virtual network elements and the fault reporting scheme, but it is only applicable to OSS supporting virtualized networks and cannot be compatible with traditional OSS

Embodiment 1

[0093] Figure 8 It is a schematic structural diagram of a system capable of reporting faults in Embodiment 1 of the present invention, as shown in Figure 8 As shown, the system mainly includes a new network element management system (E-EMS), network management system (OSS / BSS), network function virtualization dispatch center (NFVO), virtual network element management center (VNFM), virtual resource management center (VIM), network function virtualization resources (NFVI), virtual and physical network elements.

[0094] In this embodiment, the EMS mainly manages two kinds of physical network elements and two corresponding virtual network elements (in the specific deployment, it is not limited to these two types of network elements); respectively: Home Subscriber Server (HomeSubscriberServer, HSS), call Session Control Function (CallSessionControlFunction, CSCF), but not limited to HSS and CSCF. Among them, the CSCF further includes three types of CSCFs, which are Proxy-CSCF...

Embodiment 2

[0101]The fault reporting mechanism based on this embodiment is the same as that of Embodiment 1. In this embodiment, the correspondence between fault information and reported information (i.e. the mapping table of VNF, virtual machine, virtual resource and hardware resource) is stored in the VNFM, and the corresponding , VNFM will send the fault information and mapping table to E-EMS after getting hardware resource fault, virtual resource fault, virtual machine fault and virtual network element fault information, and E-EMS will associate the fault and E-EMS forward The relevant fault information and fault related information are sent to the OSS, and the OSS handles the fault.

[0102] Figure 9 It is a schematic flow chart of a fault reporting method described in Embodiment 2 of the present invention, such as Figure 9 As shown, the process specifically includes:

[0103] Step 901: The VNFM receives hardware resource failure information, virtual resource failure information...

Embodiment 3

[0115] The fault reporting mechanism based on this embodiment is the same as Embodiment 1. In this embodiment, the VNFM does not store the mapping relationship table of VNF, virtual machine, virtual resource and hardware resource, and the hardware resource fault, virtual resource fault, virtual After receiving machine failure and virtual network element failure information, the VNFM forwards the relevant failure information to the E-EMS. The E-EMS does not get the mapping relationship table, so it requests the mapping relationship table of specific faults from the VNFM, and the VNFM requests the mapping relationship between virtual machines, virtual resources and hardware resources from the VIM, and the VIM sends the mapping relationship to the VNFM. After the VNFM obtains the mapping relationship, it maps the virtual machine to the VNF. The VNFM sends the mapping relationship table of specific VNFs, virtual machines, virtual resources, and hardware resources to the E-EMS, and ...

Abstract

Embodiments of the present invention disclose a fault reporting method, system and related device. The fault reporting method comprises the steps as follows: an E-EMS acquires fault information and a corresponding relation between the fault information and reporting information, wherein the fault information comprises one or more of VNF (Virtual Network Function) fault information, virtual machine fault information, virtual resource fault information and hardware resource fault information; the E-EMS determines the reporting information corresponding to the acquired fault information according to the acquired fault information and the corresponding relation between the fault information and the reporting information; and the E-EMS reports the reporting information to a network management system OSS / BSS. The fault reporting method of the present invention can report faults of physical network elements, and also can report faults of virtual network elements, thus good universality is achieved; in addition, the system can be compatible with a traditional OSS and network fault management system, thereby achieving a wide application range.

Description

technical field [0001] The invention relates to network management technology, in particular to a fault reporting method, system and related devices. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) uses x86 and other general-purpose hardware and virtualization technology to carry software processing of many functions. Thereby reducing the expensive equipment cost of the network. [0003] refer to figure 1 At present, the troubleshooting process based on the virtual network function (VirtualNetworkFunction, VNF) mainly includes: [0004] 1) The VNFM receives an infrastructure failure notification related to a specific VNF instance. NFVO directly receives infrastructure faults that are not related to a specific VNF. [0005] Here, infrastructure failures related to specific VNF instances include physical infrastructure failures (1.1) and virtual infrastructure failures (1.2), and infrastructure failures not related to sp...
