Abstract

Embodiments of this application disclose a method for creating a network service NS and a related apparatus. The method includes: A management device sends a network service descriptor NSD query request to a network functions virtualization orchestrator NFVO, and then receives information about an NSD from the NFVO. Because the information about the NSD includes information about a network service deployment flavour, the management device may determine an instantiation parameter based on the information about the network service deployment flavour, to request the NFVO to create an NS instance, and a staff does not need to input the instantiation parameter by using the NFVO. In this way, operation complexity of deploying the NS instance by using the management device is reduced, and an error caused by manually inputting the instantiation parameter is avoided.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Patent Application No. PCT/CN2021/133873 filed on Nov. 29, 2021, which claims priority to Chinese Patent Application No. 202110239645.0, filed on Mar. 4, 2021. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD This application relates to the field of network function virtualization, and in particular, to a method for creating a network service (NS) and a related apparatus. BACKGROUND In a network function virtualization (NFV) technology, a virtualization technology is used to virtualize a function of a dedicated device in a conventional network into an independent application, and flexibly deploy the application on a unified infrastructure platform constructed based on other standard devices such as computing hardware, storage hardware, and network hardware. A function implemented by using the NFV technology is referred to as a network service (NS). In the conventional technology, to deploy an NS in an NFV system, an operations support system (OSS) and/or a business support system (BSS) need/needs to upload information about a network service descriptor (NSD) to a network functions virtualization orchestrator (NFVO), to enable the NFVO to deploy the NS based on the information about the NSD. However, in the conventional technology, when the NS is deployed through operating on the OSS/BSS, a staff needs to input an instantiation parameter by using the NFVO. Consequently, an operation of deploying the NS by using the OSS/BSS is complex, and an error is easily caused by manually inputting the instantiation parameter. SUMMARY Embodiments of this application provide a method for creating a network service NS and a related apparatus, to query information about an NSD from an NFVO, and request, by using information about a network service deployment flavour in the information about the NSD, the NFVO to create an NS instance. According to a first aspect, a method for creating a network service NS is provided, and the method may be applied to a management device. In the method, the management device sends a network service descriptor NSD query request to a network functions virtualization orchestrator NFVO, and then receives information about an NSD from the NFVO. Because the information about the NSD includes information about a network service deployment flavour, the management device may determine an instantiation parameter based on the information about the network service deployment flavour, to request the NFVO to create an NS instance, and a staff does not need to input the instantiation parameter by using the NFVO. In this way, operation complexity of deploying the NS instance by using the management device is reduced, and an error caused by manually inputting the instantiation parameter is avoided. In an embodiment, the management device receives an NSD information list sent by the NFVO, and the NSD information list includes information about at least one NSD. In this way, the management device may select the information about the NSD from information about at least one NSD in the NSD information list based on an actual requirement. For example, if an NS needed by an OSS/BSS is a next generation mobile core network (EPC) service, the OSS/BSS may search the NSD information list for information about an NSD named related to the EPC service (for example, EPC or the next generation mobile core network service), and then select the information about the NSD. In an embodiment, the information about the NSD includes information about at least one network service deployment flavour. In this way, the management device may select the information about the network service deployment flavour from the information about the at least one network service deployment flavour based on a requirement of a to-be-deployed NS instance. For example, if a main function of the to-be-deployed NS instance is to store data, and information about a network service deployment flavour may implement the data storage function, the OSS/BSS may select the information about the network service deployment flavour. In an embodiment, the information about the network service deployment flavour includes an identifier of the network service deployment flavour NSDF, an identifier of at least one virtualized network function descriptor VNFD, and/or an identifier of at least one physical network function descriptor PNFD. In this way, the management device may obtain, based on the identifier of the NSDF, the identifier of the at least one VNFD, and/or the identifier of the at least one PNFD, the instantiation parameter for deploying the NS instance. In an embodiment, the identifier of the at least one VNFD includes an identifier of a first VNFD. In this way, the management device may obtain information about a first virtualized network function VNF instance based on the identifier of the fi
