Embodiment 1

[0193] An embodiment of the present invention provides a method for processing lifecycle events, specifically as figure 2 shown, including:

[0194] S201. The VNFM obtains N concurrent life cycle events of the same VNF.

[0195] Wherein, N≥2, and N is an integer. The life cycle event may specifically be VNF instantiate, VNF dynamic scaling (scale in / out / up / down), VNF self-healing (heal), VNF software upgrade (upgrade), VNF software update (update), Modify VNF configuration (configure), query VNF status (query), delete VNF (terminate), etc.

[0196] Usually, lifecycle events are triggered when OSS / BSS or NFVO sends an operation request, or when EMS or VNF notifies VNFM of VNF status changes, or when VIM notifies VNFMVNF of related resource status changes.

[0197] S202. If there is no conflicting event group among the N lifecycle events, the VNFM sequentially triggers the processing of the N lifecycle events according to the predefined virtual network function component VNF...

Embodiment 2

[0289] The embodiment of the present invention provides a VNFM140, specifically as Figure 14 As shown, it includes: an acquisition unit 1401 and a first trigger unit 1402 .

[0290] Wherein, the acquiring unit 1401 is configured to acquire N concurrent lifecycle events of the same VNF, where N≥2, and N is an integer.

[0291] The first triggering unit 1402 is configured to sequentially trigger the processing of the N life cycle events according to the predefined VNFC priority and event type priority if there is no conflicting event group among the N life cycle events, Wherein, the conflicting event group includes at least two lifecycle events, and the at least two lifecycle events point to the same VNFC.

[0292] Further, such as Figure 15 As shown, the VNFM 140 provided by the embodiment of the present invention may further include: a first discarding unit 1403 and a second triggering unit 1404 .

[0293] Wherein, the first discarding unit 1403 is configured to, after th...

Embodiment 3

[0337] The embodiment of the present invention provides a VNFM210, specifically as Figure 21 As shown, including: processor 2010.

[0338] The processor 2010 is configured to obtain N concurrent lifecycle events of the same VNF, where N≥2, and N is an integer.

[0339] The processor 2010 is further configured to trigger the processing of the N life cycle events sequentially according to the predefined VNFC priority and event type priority if there is no conflicting event group among the N life cycle events, wherein , the conflicting event group includes at least two life cycle events, and the at least two life cycle events point to the same VNFC.

[0340] Further, the processor 2010 is further configured to discard the at least one set of conflicting event groups if there is at least one set of conflicting event groups among the N life cycle events after acquiring the concurrent N lifecycle events of the same VNF. lifecycle events in the event group, so that the remaining l...

Abstract

Embodiments of the present invention provide a life cycle event processing method and a VNFM, which can avoid processing errors that may be caused by multiple life cycle events. The method includes: the virtual network function manager VNFM obtains N concurrent life cycle events of the same virtual network function VNF; if there is no conflicting event group in the N life cycle events, according to the predefined virtual network function component VNFC The priority and event type priority sequentially trigger the processing of the N lifecycle events, wherein the conflicting event group includes at least two lifecycle events, and the at least two lifecycle events point to the same VNFC. The invention is applicable to the technical field of communication.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method for processing life cycle events and VNFM. Background technique [0002] With the development of communication technology, Network Function Virtualization (Network Function Virtualization, NFV) technology is becoming more and more mature. [0003] Under the NFV system, the existing standards only consider the situation that a virtualized network function (Virtualized Network Function, VNF) encounters one lifecycle event, but does not consider the situation that the VNF encounters multiple lifecycle events at the same time. However, in practical applications, there may be situations where a VNF encounters multiple life cycle events at the same time. For example, multiple VNFCs belonging to a VNF simultaneously generate elastic scaling requests. Another example is the Operations Support Systems (OSS) Simultaneously with the VNF, a request for a life cycle e...
