Description

Virtual resource management method and device and computer readable storage medium
Technical Field
The present invention relates to, but not limited to, wireless communication systems, and more particularly, to a method and apparatus for processing virtual resources and a computer readable storage medium.
Background
At present, in order to improve the flexibility of the communication Network and reduce the Management cost, the European Telecommunications Standards Institute (ETSI) has initiated and proposed the Network function Virtualization Management and organization (NFV-MANO) concept. In the case of using NFV (Network Functions Virtualization) technology, the original physical Network element device is replaced by a Virtualized Network Function (VNF), which is isolated from the underlying Network Function Virtualization Infrastructure (NFVI), so that the Network Function is decoupled from the specific hardware.
Based on network virtualization, the industry has further started a new generation of networks (5)thGeneration, 5G, fifth Generation), third Generation partnership project (3GPP )rdThe Generation Partnership Project) organization provides a concept of Network Slice (Network Slice) to solve the problems of rapid compilation, deployment, operation and maintenance of end-to-end Network services in different service scenarios. Network slice, which mainly refers to an instantiated logical network composed of a set of network functions (including network resources supporting these network functions) with specific network characteristics, which is used to meet the requirements of a certain class of specific network services, wherein the network characteristics can beThe method refers to ultra-low time delay, ultra-high reliability, ultra-large bandwidth and the like. A network slice is obtained from instantiation of a network slice blueprint and is therefore also referred to as a network slice instance. Different network slices are intended to meet the requirements of different types of applications and therefore typically have different performance requirements. The Network Slice is divided into a plurality of Slice subnets (Network Slice Subnet) according to the technology domain. For example, a Radio Access Network (RAN) slice subnet, a Core Network (CN) slice subnet, and a Transmission Network (TN) slice subnet.
FIG. 1 is a diagram of a reference architecture of a network slice management system and NFV-MANO in the related art. As shown in fig. 1, includes: 3GPP management system 10, NFV-MANO20, VNF30, NFVI40, and PNF (Physical Network Function) 50. The 3GPP Management system 10 includes a Network Slice Management system 11 and an EM (Element Management Function) 12, where the Network Slice Management system 11 includes a Communication Service Management Function (CSMF) 111, a Network Slice Management Function (NSMF) 112, and a Network Slice Subnet Management Function (NSSMF) 113. The NFV-MANO20 includes an NFV Orchestrator (NFVO), a Network Functions Virtualization editor (VNF) 21, a VNF Manager (VNFM), 22, and a Virtual Infrastructure Manager (VIM), 23, which may include a plurality of EMs 12, constituting an Element Management System (EMs).
The conventional maintenance management function is performed on the VNF30 through the EM12, and the lifecycle management function of the VNF30 is performed through the VNFM 22. The underlying virtual infrastructure NFVI40 is managed by VIM 23. Specific network traffic is typically accomplished through one or more VNF instances. The network functions are managed by NFVO 21. After network function virtualization is realized, a network service instance is established, a VNF instance required by the network service needs to be generated, one or more VNF instances form the network service instance, and the network service is provided through the network service instance.
Wherein, CSMF111 manages network traffic; the NSMF112 manages network slices, and the NSSMF113 manages network slice subnets. The network slice management system 11 organizes the communication service requirements into requirements for virtual network functions according to the network slice blueprint and issues the requirements to the NFV-MANO20, and deploys VNFs required for network slices (or network slice subnets) through the NFV-MANO 20.
Due to the limitation of actual networking and environment, the network slice management system may be connected with a plurality of sets of NFV-MANO systems, or may be connected with a plurality of sets of data centers through one set of NFV-MANO systems, and when the related processing of virtual resources is performed, the virtual resources cannot be sensed, so that the processing efficiency is affected.

In one embodiment, the NFV-MANO adds a northbound interface, provides reporting and provides queries for virtual resource data of the NFV-MANO management data center. The virtual resource data of the data center comprises: identification of NFVO, data center identification, data center location, available resource information, used resource information, etc.

First embodiment
The present embodiment provides a virtual resource management method, as shown in fig. 4, including:

In this embodiment, the virtual resource data is collected in a manner that the NFVO actively reports, it should be noted that a manner that the virtual resource processing device initiates collection of the virtual resource data may also be adopted, that is, the virtual resource processing device queries the NFVO for the virtual resource data, and the NFVO returns the virtual resource data to the virtual resource processing device after receiving a query request of the virtual resource processing device.
In step 402, the virtual resource processing apparatus analyzes the collected virtual resource data to generate an analysis result.
During analysis, virtual resources are distinguished according to the NFV-MANO and the identification of the data center, virtual resources which are used by network functions in the network slice and the network slice subnet in the virtual resource data are distinguished according to the identification of the network slice and the network slice subnet of the network function to which the virtual resources belong, and the virtual resources are analyzed by taking the network slice and the network slice subnet as units. It can be derived which network slices and network slice subnets have been deployed in the data centers managed by the NFV-MANO management system, how much virtual network resources are used by the network functions, and which remaining resources are available to these data centers.

Compared with the prior art, the method and the device have the advantages that the virtual resource data cannot be acquired, the virtual resource using condition cannot be acquired, and therefore the conditions that the deployment fails or needs to be redeployed due to the fact that the available virtual resources of the NFV-MANO and the data center are insufficient are likely to occur.

Step 503, the virtual resource processing device analyzes the collected virtual resource data to generate an analysis result;
during analysis, virtual resources are distinguished according to the NFV-MANO and the identification of the data center; in the virtual resource data, the virtual resource data used by the network slice and the network functions in the network slice subnet are distinguished according to the identifiers of the network slice and the network slice subnet of the network function to which the virtual resource belongs, and are analyzed by taking the network slice and the network slice subnet as units. It can be derived which network slices and network slice subnets have been deployed in the data center managed by the NFV-MANO management system, how much virtual network resources are used by the network functions of these network slices and network slice subnets, while which remaining virtual resources are available to the data center.
Step 504, when the virtual resource of a certain data center is increased or decreased due to a certain reason, the NFVO reports the change of the virtual resource to the virtual resource processing device;
505, the virtual resource processing device collects the change of the virtual resource, and judges that the change has important influence on the network slice and the network slice subnet, and needs to perform corresponding automatic maintenance processing on a certain network slice and the network slice subnet;
the first judgment condition can be preset, if the parameter set in the first judgment condition is reached, the resource change has an important influence on the network slice and the network slice subnet, and the first judgment condition can be set.
It should be noted that, the analysis of the virtual resource in step 503 may also be performed in step 505. During analysis, only the influence of the change of the virtual resources on the network slice or the network slice subnet can be analyzed, and the analysis of which residual virtual resources can be used by the data center is not needed.
In step 506, the virtual resource processing apparatus sends a self-optimization operation request or a self-configuration operation request to the NSMF or the NSSMF.
In step 507, the NSMF or NSSMF completes the self-optimization or self-configuration operation according to the self-optimization operation request or the self-configuration operation request of the virtual resource processing apparatus.
In another embodiment, in step 503, when the virtual resource processing apparatus analyzes the virtual resource data, it may determine that the virtual resource changes, and initiate the automatic maintenance process.
In this embodiment, the automatic maintenance processing for the network slice and the network slice subnet is generated according to the virtual resource change managed by the NFV-MANO, and is performed for different types of network slices, thereby ensuring that different management strategies are adopted for management, meeting the requirements of specific network services, and further ensuring correct maintenance and management of the 5G network to which the network slice is applied.
