Embodiment 1

[0101] In this embodiment, a virtualized network function scaling method is provided, and the steps are as follows:

[0102] The EMS obtains the VNF specification information corresponding to the VNF instance (that is, the information of the preset deployment specification of the VNF instance);

[0103] The EMS judges whether the VNF instance needs to be scaled; if it needs to be scaled, go to the next step, otherwise this process is introduced;

[0104] EMS determines to which specification the VNF instance should be scaled;

[0105] The EMS sends a VNF instance scaling request to the VNFM. The parameters contained in the request include: the unique identifier of the VNF that needs to be scaled, and the specification to which the determined VNF instance needs to be scaled;

[0106] After VNFM receives the VNF instance scaling request, it performs the scaling operation on the corresponding VNF instance;

[0107] The EMS receives the VNF instance scaling completion message re...

Embodiment 2

[0116] In this embodiment, another virtualized network function scaling method is provided, and the steps are as follows:

[0117] EMS obtains the VNF specification information corresponding to the VNF instance from the system database through the private interface;

[0118] EMS judges whether the VNF instance needs to be scaled or not according to the performance data of the VNF and the preset performance threshold; if it needs to be scaled, go to the next step; otherwise, this process is introduced;

[0119] The EMS determines which specification the VNF instance should scale to according to the VNF specification information corresponding to the VNF instance and the desired capability of the VNF instance;

[0120] The EMS sends a VNF instance scaling request to the VNFM. The parameters contained in the request include: the unique identifier of the VNF that needs to be scaled, and the specification to which the determined VNF instance needs to be scaled;

[0121] After VNFM ...

Embodiment 3

[0124] The method for scaling virtualized network functions provided in this embodiment includes the following steps:

[0125] EMS obtains the VNF specification information corresponding to the VNF instance from the database through the private interface;

[0126] The EMS receives the "VNF scaling" command from the NMS, and the parameters of the command include the "id of the VNF instance to be scaled" (vnfr_id) and the "capability of the VNF after scaling" (deployment_flavour-flavour_key).

[0127] EMS determines the capability that the VNF instance needs to reach after scaling according to the "capability to reach after VNF scaling" (deployment_flavour-flavour_key). For example, when the VNF instance is a vPGW (virtual PDN gateway-Packet Data Network Gateway), here The "capability to be achieved after VNF scaling" is that the number of calls per second (calls per second) is 10K, that is, it supports a maximum of 10,000 calls per second. Then determine the specification ID c...

Abstract

The invention provides a virtualized network function VNF instance scaling method and a VNF instance scaling device. The method comprises the following steps: an element management system EMS determines a VNF instance needing scaling and an expected deployment flavor to which the VNF instance needs to be scaled; the EMS sends the identity of the VNF instance and scaling information determined according to the expected deployment flavor to a virtualized network function manager VNFM, wherein the identity of the VNF instance and the scaling information are used to instruct the VNFM to scale the VNF instance according to the scaling information. Through the method and the device, the problem that VNF scaling cannot be realized through EMS's trigger in the related technology is solved, VNF instance scaling is realized through EMS's trigger, and the trigger speed of VNF instance scaling is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for scaling a virtualized network function (VNF) instance. Background technique [0002] In the field of wireless communication system management, the interface between the Network Management System (NMS for short) and the Element Management System (EMS for short) is called a northbound interface (Itf-N). The EMS mainly completes the function of the Element Management Layer (EML) in the Telecommunications Management Network (TMN) of the International Telecommunication Union (ITU) for short, that is, completes one or more For the management function of mobile communication equipment, EMS between different equipment suppliers usually cannot be used universally. The NMS mainly completes the network management layer (Network Management Layer, NML for short) function in the ITU TMN, and is responsible for the management of all network elements in a managed networ...
