Alarm information processing method, related device, and system

An alarm information processing method, comprising:

• performing, by a virtualized infrastructure manager (VIM), correlation analysis on at least two pieces of alarm information to generate virtual machine (VM) alarm information according to alarm information parameters;
• and
• reporting, by the VIM, the generated VM alarm information to a virtualized network function manager (VNFM), wherein the VM alarm information is used for the VNFM reporting a first alarm message to an element management system (EMS) for performing correlation analysis according to a preset time correlation rule and a preset space correlation rule for grouping the alarm information having a correlation relationship on the first alarm message and a second alarm message that is reported by a virtualized network function (VNF), and for dispatching a work order for the alarm information having the correlation relationship, wherein the first alarm message comprises a first object identity comprising a VNF identity, wherein the first alarm message comprises a first alarm association information and a first alarm information set, the first alarm association information and the second alarm message comprises a second alarm association information and a second alarm information set, the second alarm association information and the first alarm information set is a fault tree and the second alarm information set is a fault tree.

An alarm information processing apparatus, comprising wherein an element management system (EMS), the EMS comprising:

• a first EMS communications interface, configured to receive a first alarm message reported by a virtualized network function manager (VNFM), wherein the first alarm message comprises a first alarm association information and a first alarm information set, the first alarm association information comprising a first object identity comprising a virtualized network function (VNF) identity, wherein the first alarm information set is a fault tree;
• a second EMS communications interface, configured to receive a second alarm message reported by a VNF, the second alarm message comprising a second alarm association information and a second alarm information set, the second alarm association information comprising a second object identity, wherein the second object identity comprises a VNF identity, wherein the second alarm information set is a fault tree;
• and
• an EMS processor, configured to:
• perform, according to the first alarm association information and the second alarm association information, and further according to a preset time correlation rule and a preset space correlation rule for grouping the alarm information having a correlation relationship, correlation analysis on the first alarm message received by the first EMS communications interface and the second alarm message received by the second EMS communications interface;
• and
• dispatch a work order for the alarm information having the correlation relationship.

An alarm information processing apparatus, wherein the apparatus is a virtualized infrastructure manager (VIM), the apparatus comprising:

• a processor, configured to perform correlation analysis on at least two pieces of alarm information to generate virtual machine (VM) alarm information according to alarm information parameters;
• and
• a first communications interface, configured to report the VM alarm information generated by the processor to a virtualized network function manager (VNFM), wherein the VM alarm information is used for the VNFM reporting a first alarm message to an element management system (EMS) for performing correlation analysis according to a preset time correlation rule and a preset space correlation rule for grouping the alarm information having a correlation relationship on the first alarm message and a second alarm message that is reported by a virtualized network function (VNF), and for dispatching a work order for the alarm information having the correlation relationship, wherein the first alarm message comprises a first object identity comprising a VNF identity, wherein the first alarm message comprises a first alarm association information and a first alarm information set, the first alarm association information and the second alarm message comprises a second alarm association information and a second alarm information set, the second alarm association information and the first alarm information set is a fault tree and the second alarm information set is a fault tree.
