All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second," and the like in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not set forth for a listed step or element but may include steps or elements not listed.
The network slice processing method provided by the embodiment of the invention is mainly realized by a global virtualization infrastructure of network slices as services based on NFV and BFV technologies.
At present, the network Slicing is a service nsaas (network Slicing as a service) implementation architecture is mainly based on NFV, and service Slicing of a network layer can be implemented in a relatively flexible manner. The NFV divides the description of the network service slice into three layers, the top layer is the description of the application service, the middle layer is the description of the network function and the SLA service, and the stratum is the description layer of the infrastructure service. The NSaas developer defines a mapping relation according to service descriptions of an application layer, such as flow characteristics, SLAs and the like, maps the service descriptions into SLAs and network function descriptions of a network layer, searches service descriptions registered by existing network providers to find a provider network service collection to meet the network layer service descriptions, and directly maps application service descriptions related to hardware infrastructure into service descriptions of an infrastructure layer.
However, in an actual scenario facing an industry/enterprise customer, a network slice must be used in combination with a B domain (service domain) function such as user self-service, service provisioning, charging, service quality assurance, and user experience management, so that services and data of an O domain (operation domain)/B domain (service domain) are merged to provide a uniform network slice management and use specification.
For a large amount of B-domain network slicing services which need to be combined with the existing services of users, because NFV is limited to the characteristics of network domains, the customization difficulty of opening O/B domain data and services is high, and thus the flexibility of network slicing is limited. Therefore, in the embodiment of the present invention, a global virtualization architecture is provided to implement network slicing processing.
Referring to fig. 1, a schematic diagram of a global virtualization architecture provided in the present invention is shown. BFV (Business Function virtualization) technology is applied to the global virtualization framework. BFV encapsulates B domain services such as existing charging service, network service opening, service quality assurance, user experience management, user self-service management, intelligent data analysis and arrangement service and the like into micro-services, and meanwhile, data pools of an O domain and a B domain are fused on a data layer to provide unified standard support for virtualization and customization of the B domain services. Through NFV and BFV technical frameworks, operators can be helped to get through the whole flow rapidly, personalized requirements of industry/enterprise customers are supported, network slices suitable for self business characteristics are customized, and universe service virtualization is achieved.
At the application layer, the method is divided into a network slice self-service portal and an NSaaS API. The self-service portal provides a one-stop type NSaaS management platform, and can manage functions of slice definition, slice operation monitoring, slice service quality, user experience and the like. The NSaaS API provides a secondary development interface of an application program, opens various management functions of the NSaaS and is convenient to integrate into other systems.
At the NFV/BFV layer, definition and mapping management of network layer slices and business system slices is provided. The layer provides service slices of B domains such as virtual CRM service, virtual charging service, virtual data analysis service and the like besides network layer services provided by the traditional NFV. Network service slices and B-domain service slices of NFV implement collaborative operations (MANO) through a unified orchestration manager. The MANO manager distributes virtual infrastructures through VIM, manages B-domain microservices through the microservice manager and VNFM/VBFM/VOFM, and integrates the B-domain microservices and O-domain network slices through configuring and integrating a data pool of an O/B-domain data source.
Through the global virtualization framework, network slices are provided for industry/enterprise customers, and meanwhile, the corresponding software-defined OSS/BSS system is also provided, so that the requirement for rapid development of business of the industry/enterprise customers is met. According to the scheme, the service of the B domain is integrated into the network slice, and is opened through the NSaaS portal and the NSaaS API, so that an industry client can use the OSS/BSS system service in the slice.
The unified NSaaS management platform is provided, basic functions of agile release, convenient deployment, gray scale upgrading and automatic elasticity are provided for VNF, VBF and VOF, and the industry and enterprises are enabled to be more concentrated on the application. The scheme integrates O/B domain services and data, provides services such as virtual CRM, virtual billing, intelligent data analysis, micro-service arrangement and the like, and enables an enterprise to concentrate on application and innovation.
The requirements from the network service to the matching service system are described through a uniform network slice, namely a service template, and uniform arrangement is supported. The scheme provides an NSaaS portal, and realizes the unified arrangement of O/B domain services by integrating a VIM and a micro service manager; by consolidating the O/B domain's data pools, the service slice can access the global data and comply with business rules. The NSaaS defines a B-domain service description in the template in addition to the network SLA description, and maps the appropriate B-domain service to the microservice.
