具体实施方式detailed description
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
应理解，本发明实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access， WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***、以及未来的5G通信***等。It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a wideband code. Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) System, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, and future 5G communication system Wait.
本发明实施例涉及网络切片技术。网络切片技术是将网络在逻辑上抽象为一个或者多个网络切片，其中每个网络切片包含一系列的逻辑网络功能，针对性地满足不同业务类型的差异化需求。例如在第五代移动通信(The 5th Generation，简称为“5G”)网络中，网络切片是一种按需组网的方式，为运营商带来能根据不断变化的用户需求进行调整，并快速满足新型应用需求的新服务。Embodiments of the present invention relate to network slicing techniques. The network slicing technology logically abstracts the network into one or more network slices, where each network slice contains a series of logical network functions to specifically meet the differentiated requirements of different service types. For example, in the fifth generation mobile communication (The 5th Generation, referred to as "5G") network, network slicing is an on-demand networking, which enables operators to adjust according to changing user requirements and quickly New services that meet the needs of new applications.
网络切片技术将5G网络物理基础设施资源根据场景需求抽象为多个相互独立的平行的网络切片实例。每个网络切片实例按照业务场景的需要和业务模型进行网络功能的定制裁剪及相应网络功能的编排管理。一个网络切片实例可以视为一个实例化的5G网络。这样的网络结构允许运营商将网络作为一种服务提供给用户，并可以根据速率、容量、覆盖性、延迟、可靠性、安全性和可用性等指标对实体网络进行自由组合，从而满足不同用户的要求。The network slicing technology abstracts the 5G network physical infrastructure resources into a plurality of independent parallel network slice instances according to the scene requirements. Each network segment instance performs customized tailoring of network functions and management of corresponding network functions according to the needs of the business scenario and the business model. A network slice instance can be thought of as an instantiated 5G network. Such a network structure allows operators to provide the network as a service to users, and can freely combine physical networks according to indicators such as rate, capacity, coverage, delay, reliability, security, and availability to meet different users. Claim.
在网络切片技术中，网络切片生命周期管理是一个需要重点考虑的问题。网络切片生命周期管理包括网络切片实例的创建、组合、更新和删除等等。对于网络切片实例的创建、组合和更新，应该为每个网络切片实例确定可用的网络资源，并且为其配置特定的网络功能和参数。对于网络切片实例的删除，应该释放掉那些特定的网络功能和网络资源。In network slicing technology, network slice lifecycle management is a key issue to consider. Network slice lifecycle management includes the creation, composition, update, and deletion of network slice instances. For the creation, composition, and update of network tile instances, the available network resources should be determined for each network slice instance and configured with specific network functions and parameters. For the deletion of network slice instances, those specific network functions and network resources should be released.
需要说明的是，本文中的术语“网络管理架构”“网络***”、“***”等可以互相替换。为了便于理解，先介绍本文中出现的一些术语。It should be noted that the terms "network management architecture", "network system", "system" and the like may be replaced with each other. For ease of understanding, some of the terms that appear in this article are introduced.
网络切片(Network slice)：指在物理或者虚拟的网络基础设施之上，根据不同的服务需求定制化不同的逻辑网络。网络切片可以是一个包括了接入网和核心网的完整的网络，能够提供电信服务，具有一定网络能力。网络切片可能具有如下一个或多个特性：接入网可能切片，也可能不切片。接入网可能是多个网络切片共用的。不同的网络切片的特性和组成他们的网络功能可能是不一样。Network slice: refers to the customization of different logical networks based on different service requirements on a physical or virtual network infrastructure. The network slice can be a complete network including the access network and the core network, capable of providing telecommunication services and having certain network capabilities. A network slice may have one or more of the following characteristics: the access network may or may not slice. The access network may be shared by multiple network slices. The characteristics and composition of different network slices may be different for their network functions.
网络切片实例(Network slice instance,NSI)：是一个真实运行的逻辑网络，能满足一定网络特性或服务需求。一个网络切片实例可能提供一种或多种服务。网络切片实例可以由网管***创建，一个网管***可能创建一个或多个网络切片实例并同时对它们进行管理，包括在网络切片实例运行过程中的性能监视和故障管理等。当多个网络切片实例共存时，网络切片实例之间可能共享部分网络资源和网络功能。网络切片实例可能从网络切片模板创建，也可能不从网络切片模板创建。Network Slice Instance (NSI): A real-world logical network that meets certain network characteristics or service requirements. A network slice instance may provide one or more services. A network slicing instance can be created by a network management system. A network management system may create one or more network slicing instances and manage them at the same time, including performance monitoring and fault management during the running of the network slicing instance. When multiple network slice instances coexist, some network resources and network functions may be shared between network slice instances. A network tile instance may or may not be created from a network tile template.
一个完整的网络切片实例可以提供完整的端到端的网络服务的。网络切片实例的可以包括网络功能。网络功能可以包括物理网络功能和/或虚拟网络功能。以下统称物理网络功能和/或虚拟网络功能为网络功能。A complete network slicing instance can provide complete end-to-end network services. Network segment instances may include network functionality. Network functions may include physical network functions and/or virtual network functions. The following are collectively referred to as physical network functions and/or virtual network functions as network functions.
网络切片模板：是指生成网络切片实例的一种方式，用于给生成网络切片实例提供一个参考。网络切片模板规定了网络切片实例应该如何生成。例如，网络切片模块可以指示网络切片包含哪些网络功能，应达到的关键绩效指标(Key Performance Indicators， 简称为“KPI”)等。Network Slice Template: A method of generating a network slice instance to provide a reference for generating a network slice instance. The network slice template specifies how the network slice instance should be generated. For example, the network slicing module can indicate which network functions are included in the network slice, and Key Performance Indicators (KPIs) that should be achieved.
网络功能：是网络中的一种处理功能，定义了功能性的行为和接口，网络功能可以通过专用硬件实现，也可以通过在专用硬件上运行软件实现，也可以在通用的硬件平台上以虚拟功能的形式实现。因此，从实现的角度，可以将网络功能分为物理网络功能和虚拟网络功能。而从使用的角度，网络功能可以分为专属网络功能和共享网络功能，具体地，对于多个网络切片实例而言，可以独立地使用不同的网络功能，这种网络功能称为专属网络功能，也可以共享同一个网络功能，这种网络功能称为共享网络功能。Network function: It is a processing function in the network, which defines functional behaviors and interfaces. The network functions can be implemented by dedicated hardware, or by running software on dedicated hardware, or by virtualizing on a common hardware platform. The form of the function is implemented. Therefore, from the perspective of implementation, network functions can be divided into physical network functions and virtual network functions. From the perspective of use, network functions can be divided into dedicated network functions and shared network functions. Specifically, for multiple network slice instances, different network functions can be used independently. This network function is called a dedicated network function. It is also possible to share the same network function, which is called a shared network function.
为了便于理解本发明实施例，首先介绍图1中的网络管理架构。图1示出了一种网络管理架构100。作为一个示例，图1的网络管理架构100可以是融合了网络功能虚拟化(Network function virtualized，简称为“NFV”)管理与编排(Management and orchestration，简称为“MANO”)模块的3GPP公共陆地移动网络(Public Land Mobile Network，简称为“PLMN”)网络管理架构。具体而言，网络管理架构100同时包含了管理物理网络功能和虚拟网络功能的模块。下面依次介绍网络管理架构100中的模块。In order to facilitate the understanding of the embodiments of the present invention, the network management architecture in FIG. 1 is first introduced. FIG. 1 illustrates a network management architecture 100. As an example, the network management architecture 100 of FIG. 1 may be a 3GPP public land mobile that incorporates a network function virtualized (NFV) management and orchestration (MANO) module. Network (Public Land Mobile Network, referred to as "PLMN") network management architecture. Specifically, the network management architecture 100 includes modules for managing physical network functions and virtual network functions. The modules in the network management architecture 100 are described in turn below.
物理网络功能(Physical network function,PNF)模块：是提供固定的网络功能的物理设备。例如，物理网络功能模块可以是传统的3GPP网络管理架构中的网元(Network element,NE)，也就是说物理网元。例如，NE可以是基站、移动管理实体(Mobility management entity,MME)或服务网关(Serving Gateway,简称为“SGW”)等。Physical network function (PNF) module: A physical device that provides fixed network functions. For example, the physical network function module may be a network element (NE) in a traditional 3GPP network management architecture, that is, a physical network element. For example, the NE may be a base station, a Mobility Management Entity (MME), or a Serving Gateway (SGW).
虚拟网络功能(Virtualized network function,VNF)模块：可以是网络管理架构中可以监视和管理的最小虚拟单位。VFN与下文所述的NFVI模块之间存在通信接口。VNF模块可以在NFVI的基础上，创建虚拟网络功能并做一些参数配置，实现某一个网络功能。Virtualized network function (VNF) module: It can be the smallest virtual unit that can be monitored and managed in the network management architecture. There is a communication interface between the VFN and the NFVI module described below. The VNF module can create virtual network functions and perform some parameter configuration on the basis of NFVI to implement a certain network function.
网元管理器(Element manager，简称为“EM”)：用于管理网元的网络模块。EM即可以用于管理物理网络功能(即PNF模块)，也可以用于管理虚拟网络功能(即VNF模块)。Element manager ("EM"): A network module for managing network elements. EM can be used to manage physical network functions (ie PNF modules) or to manage virtual network functions (ie VNF modules).
域管理器(Domain manager，简称为“DM”)：比EM的管理范围更大一级的管理***模块。DM可以管理一个或多个EM，例如，DM可以是厂商的管理***。Domain manager ("DM"): A management system module that is one level larger than the management scope of EM. The DM can manage one or more EMs, for example, the DM can be a vendor's management system.
需要说明的是，EM和DM在定义上是不同的，EM是直接管理同一类型的网络设备，比如EM管理一系列的基站，DM管理属于设备商(英文：vendor)的网络设备，提供域管理功能的，DM比EM的管理范围更大。通常情况下，EM设备用于执行网络功能的配置。但本发明实施例中，DM也可能管理PNF和/或VNF，相应地，DM也可能执行EM所执行的步骤。It should be noted that EM and DM are different in definition. EM directly manages the same type of network equipment. For example, EM manages a series of base stations, and DM manages network equipment belonging to equipment vendors (English: vendor), providing domain management. Functional, DM is more manageable than EM. Typically, EM devices are used to perform configuration of network functions. However, in the embodiment of the present invention, the DM may also manage the PNF and/or the VNF. Accordingly, the DM may also perform the steps performed by the EM.
网络管理器(Network manager，NM)：网络层面的管理模块，主要提供网络管理功能、管理设备之间的交换等相关功能。例如，NM可以负责网络资源的分布、配置、控制和监控等，NM由EM或DM提供支持。Network manager (NM): A network-level management module that provides network management functions and management equipment exchanges. For example, NM can be responsible for the distribution, configuration, control, and monitoring of network resources, and NM is supported by EM or DM.
网络功能虚拟基础设施(Network function virtualized infrastructure，简称为“NFVI”)模块：用于对虚拟网络功能(即VNF)进行部署，其可以是一组由软件和硬件组成的运行环境，包括虚拟层和抽象硬件资源等。Network function virtualized infrastructure (NFVI) module: used to deploy virtual network functions (VNF), which can be a set of operating environments consisting of software and hardware, including virtual layers and Abstract hardware resources, etc.
NFV-MANO***模块：其与NFVI模块、VNF模块、EM模块以及NM模块之间存在接口，以用于在网络层面管理虚拟网络功能，包含了以下三个模块：NFV-MANO system module: It has an interface with NFVI module, VNF module, EM module and NM module for managing virtual network functions at the network level, including the following three modules:
网络功能虚拟化编排(Network function virtualization orchestrator，简称为“NFVO”)模块：用于进行网络服务、VNF的生命周期管理，并从NFVI全局的角度优化网络资源。Network function virtualization orchestrator (NFVO) module: used for network service, VNF lifecycle management, and optimize network resources from the perspective of NFVI globally.
虚拟网络功能管理模块(Virtualized network function manager，简称为“VNFM”) 模块：用于在网络层面管理VNF模块。Virtualized network function manager (VNFM) module: used to manage VNF modules at the network level.
虚拟基础设施管理器(Virtualized infrastructure manager，简称为“VIM”)：与NFVI、VNF之间存在接口，用于管理NFVI的计算、存储以及网络资源的分配等。Virtualized Infrastructure Manager (VIM): There is an interface between NFVI and VNF to manage the calculation, storage, and allocation of network resources of NFVI.
由上述对网络管理架构100的介绍可知，图1中的网络管理架构100虽然能够对物理网络功能和虚拟网络功能进行管理。但是其并不能够实现网络切片实例进行管理。所以图1中的网络管理架构100不能满足未来通信***中的网络切片技术应用的需求。As can be seen from the above description of the network management architecture 100, the network management architecture 100 of FIG. 1 can manage physical network functions and virtual network functions. However, it does not enable network slice instances to be managed. Therefore, the network management architecture 100 in FIG. 1 cannot meet the requirements of network slicing technology applications in future communication systems.
本发明实施例在网络管理架构100中引入网络切片管理与编排模块(Network slice manager and orchestrator，简称为“NSM&O”)，并通过NSM&O对网络切片实例的创建过程进行管理，以实现网络切片实例的自动化创建，提高管理网络切片实例的效率。The embodiment of the present invention introduces a network slice manager and orchestrator (NSM&O) in the network management architecture 100, and manages the process of creating a network slice instance through NSM&O to implement a network slice instance. Automated creation to improve the efficiency of managing network slicing instances.
下文介绍本发明实施例的网络管理架构。本发明实施例在现有的网络管理架构100的基础上，引入了NSM&O模块。其中NSM&O模块的结构示意图如图2所示，其主要功能包括以下任一项：The network management architecture of the embodiment of the present invention is described below. The embodiment of the present invention introduces an NSM&O module based on the existing network management architecture 100. The structure diagram of the NSM&O module is shown in Figure 2. Its main functions include any of the following:

As shown in FIG. 3, the network management architecture 300 is a network management architecture that is enhanced and modified based on the network management architecture 100. The network management architecture 300 does not include an NM module, but the NSM&O module performs the functions performed by the NM module in the network management architecture 100. In other words, the NSM&O module can include all the functions of the NM module in addition to the functions shown in FIG. 2. The NSM&O module can interact with the EM and/or DM through a communication interface to implement management of network functions corresponding to the network slice instance. Among them, the management of the network function includes the management of the PNF module and the VNF module.

The network management architecture 400 is different from the network management architecture 300 in that the network management architecture 300 does not include an NFVO module. In the network management architecture 400, the functionality of the NFVO module is implemented by the NSM&O module. In other words, the NSM&O module's capabilities include the management of virtual network resources and VNF lifecycle management. There is a communication interface between the NSM&O module and the VNFM module. In Figure 4, this interface can be referred to as the NG1 interface. There is a communication interface between the NSM&O module and the VIM module. In Figure 4, the interface can be referred to as an NG2 interface.

NSM&O模块与VIM模块可以通过NG2接口进行以下任一的交互：NFVI资源预留、分配、释放等；VNF软件映像(image)增加、删除、更新等；传输与NFVI相关的配置信息、事件、测量结果、升级记录等。The NSM&O module and the VIM module can perform any of the following interactions through the NG2 interface: NFVI resource reservation, allocation, release, etc.; VNF software image (image) addition, deletion, update, etc.; transmission of NFVI-related configuration information, events, measurements Results, upgrade records, etc.
对于网络管理架构400，NSM&O模块除了能够直接管理物理网络功能之外，还可以对虚拟网络功能以及VNF生命周期进行管理。从而能够统一地管理和编排物理、虚拟网络资源和功能，利于从全局化的角度优化资源。For the network management architecture 400, in addition to being able to directly manage physical network functions, the NSM&O module can also manage virtual network functions and the VNF life cycle. Therefore, it is possible to uniformly manage and orchestrate physical and virtual network resources and functions, and optimize resources from a global perspective.
图5示出了本发明实施例所应用的另一网络管理架构500。如图5所示，在网络管理架构500中保留了NM模块，NSM&O模块与NM模块相互独立。并且，NSM&O模块与NM模块之间存在通信接口。在图5中，该通信接口可以称为NG3接口。NSM&O模块与NFVO模块之间也存在通信接口。在图5中，该通信接口可以称为NG4接口。NSM&O模块与EM模块之间也存在通信接口。在图5中，该通信接口可以称为NG5接口。FIG. 5 illustrates another network management architecture 500 to which an embodiment of the present invention is applied. As shown in FIG. 5, the NM module is reserved in the network management architecture 500, and the NSM&O module and the NM module are independent of each other. Moreover, there is a communication interface between the NSM&O module and the NM module. In Figure 5, the communication interface can be referred to as an NG3 interface. There is also a communication interface between the NSM&O module and the NFVO module. In Figure 5, the communication interface can be referred to as an NG4 interface. There is also a communication interface between the NSM&O module and the EM module. In Figure 5, the communication interface can be referred to as an NG5 interface.
其中，NSM&O模块与NM模块可以通过NG3接口进行以下交互：传输NSM&O模块和NM模块之间的协商信息，例如如NSM&O模块查询NM模块已生成的VNF；NM模块向NSM&O模块反馈已生成的VNF信息，并确认允许NSM&O模块修改VNF信息；NSM&O模块通知NM模块将要对哪些PNF/VNF进行修改；NSM&O模块通知NM模块针对PNF/VNF的具体修改内容。The NSM&O module and the NM module can perform the following interactions through the NG3 interface: transmitting the negotiation information between the NSM&O module and the NM module, for example, the NSM&O module queries the VNF that has been generated by the NM module; and the NM module feeds back the generated VNF information to the NSM&O module. And confirm that the NSM&O module is allowed to modify the VNF information; the NSM&O module notifies the NM module which PNF/VNF will be modified; the NSM&O module notifies the NM module of the specific modification of the PNF/VNF.
NSM&O模块与NFVO模块之间可以通过NG4接口进行以下交互：NSM&O模块通过NG4接口参与VNF的生命周期管理，例如通知NFVO模块生成、更新、删除一个VNF等；NSM&O模块向NFVO模块查询VNF、NFVI的运行信息；NFVO模块向NSM&O模块反馈VNF、NFVI的运行信息；策略管理，NSM&O模块可以向NFVO模块发送策略，指出对VNF部署的需求；NSM&O模块通过NG4接口进行VNF包管理。The NSM&O module and the NFVO module can perform the following interactions through the NG4 interface: the NSM&O module participates in VNF lifecycle management through the NG4 interface, for example, notifying the NFVO module to generate, update, and delete a VNF; the NSM&O module queries the NFVO module for VNF and NFVI. Operation information; NFVO module feeds back NNF&O module feedback information about VNF and NFVI; policy management, NSM&O module can send policy to NFVO module, indicating the need for VNF deployment; NSM&O module performs VNF package management through NG4 interface.
NSM&O模块和EM模块之间可以通过NG5接口进行以下交互：NSM&O模块通过NG5接口与EM模块进行通信，以管理PNF和VNF(若EM支持对VNF的管理)。The NSM&O module and the EM module can communicate with each other through the NG5 interface: the NSM&O module communicates with the EM module through the NG5 interface to manage the PNF and VNF (if the EM supports the management of the VNF).
对于网络管理架构500，NSM&O模块采用了通信接口与各模块进行交互。NSM&O模块可以通过NFVO模块编排和管理虚拟资源以及参与VNF的生命周期管理NSM&O模块和NM模块都可以直接管理PNF。并且NSM&O模块和NM模块都可以通过NFVO模块或EM模块管理VNF。因此，对于PNF和VNF的管理，NSM&O模块和NM模块之间可以通过通信进行协调。For the network management architecture 500, the NSM&O module uses a communication interface to interact with each module. NSM&O modules can be used to orchestrate and manage virtual resources through NFVO modules and participate in VNF lifecycle management. NSM&O modules and NM modules can directly manage PNF. And NSM&O modules and NM modules can manage VNF through NFVO modules or EM modules. Therefore, for the management of PNF and VNF, the NSM&O module and the NM module can be coordinated through communication.
图6示出了本发明实施例所应用的另一网络管理架构600。如图6所示，网络管理架构600中也保留了NM模块。NSM&O模块与NM模块也是相互独立的。网络管理架构600与网络管理架构500的不同之处在于：网络管理架构600中不包含NFVO模块的实体。NFVO模块的功能由NSM&O模块实现。换句话说，NSM&O模块的功能还包括虚拟网络资源的编排管理以及VNF生命周期管理。其中，NSM&O模块与VNFM模块之间存在通信接口。在图6中，该通信接口可以称为NG1接口。NSM&O模块与VIM模块之间存在通信接口。在图6中，该通信接口可以称为NG2接口。NSM&O模块与EM模块之间存在通信接口。在图6中，该通信接口可以称为NG5接口。关于NG1接口、NG2接口以及NG5接口的具体功能可以参见图4和图5中的相同或相似的内容。为了简洁，此处不再赘述。FIG. 6 illustrates another network management architecture 600 to which an embodiment of the present invention is applied. As shown in FIG. 6, the NM module is also retained in the network management architecture 600. The NSM&O module and the NM module are also independent of each other. The network management architecture 600 differs from the network management architecture 500 in that the entity of the NFVO module is not included in the network management architecture 600. The functionality of the NFVO module is implemented by the NSM&O module. In other words, the NSM&O module's capabilities include the management of virtual network resources and VNF lifecycle management. Among them, there is a communication interface between the NSM&O module and the VNFM module. In Figure 6, the communication interface can be referred to as an NG1 interface. There is a communication interface between the NSM&O module and the VIM module. In Figure 6, the communication interface can be referred to as an NG2 interface.

For the sake of brevity, it will not be repeated here.
对于网络管理架构600，NSM&O模块采用了通信接口与各实体模块进行交互。NSM&O模块可以通过NFVO模块编排和管理虚拟资源以及参与VNF的生命周期管理NSM&O模块和NM模块都可以直接管理PNF。因此，对于PNF的管理，NSM&O模块和NM模块之间可以通过通信进行协调。并且由于NSM&O模块合并了NSFO模块的功能，所以NSM&O模块还可以直接编排管理虚拟网络资源和参与VNF的生命周期管理。NM模块则不管理虚拟网络资源和VNF。For the network management architecture 600, the NSM&O module uses a communication interface to interact with various entity modules. NSM&O modules can be used to orchestrate and manage virtual resources through NFVO modules and participate in VNF lifecycle management. NSM&O modules and NM modules can directly manage PNF. Therefore, for the management of the PNF, the NSM&O module and the NM module can be coordinated by communication. And because the NSM&O module incorporates the functionality of the NSFO module, the NSM&O module can also directly manage virtual network resources and participate in VNF lifecycle management. The NM module does not manage virtual network resources and VNFs.

Alternatively, a network slice instance can be divided into sub-slice instances provided by multiple different device vendors. Alternatively, a network slice instance can be divided into sub-slice instances provided by multiple different device vendors. This embodiment of the present invention does not limit this. Each subnet slice instance is managed by NSM&O for each domain. After receiving the update request message, the NSM&O management device can determine which sub-network slice instances need to be updated, and then directly notify the corresponding NSM&O to update.
作为一个可选的实施例，在S702，该NSM&O向EM发送配置请求消息之前，该方法还包括：该NSM&O确定该第一网络功能是否为共享网络功能。若该第一网络功能为共享网络功能，该NSM&O确定与该第一网络切片实例共享该第一网络功能的至少一个第二网络切片实例。该NSM&O确定第二网络切片实例是否允许增加或删除该第一网络功能。在S702，该NSM&O向EM发送配置请求消息，包括：若该全部或部分第二网络切片实例允许增加或删除该第一网络功能，该NSM&O向该EM发送该配置请求消息，该配置请求消息还用于请求为允许增加或删除该第一网络功能的该全部或部分第二网络切片实例配置该第一网络功能。具体地，配置该第一网络功能指在第二网络切片实例中增加或删除该第一网络功能。As an optional embodiment, before the NSM&O sends the configuration request message to the EM, the method further includes: the NSM&O determining whether the first network function is a shared network function. If the first network function is a shared network function, the NSM&O determines to share at least one second network slice instance of the first network function with the first network slice instance. The NSM&O determines whether the second network slice instance is allowed to add or delete the first network function. At S702, the NSM&O sends a configuration request message to the EM, including: if the all or part of the second network slice instance allows the first network function to be added or deleted, the NSM&O sends the configuration request message to the EM, and the configuration request message is further The first network function is configured to request the all or part of the second network slice instance that is allowed to add or delete the first network function. Specifically, configuring the first network function refers to adding or deleting the first network function in the second network slice instance.
该NSM&O还可以先确定该第一网络功能是共享网络功能还是专属网络功能。若该第一网络功能为专属网络功能，即仅为该第一网络切片实例提供服务，则该NSM&O可以直接确定需要进行第一网络功能的配置。若该第一网络功能为共享网络功能，那么该NSM&O需要考虑和该第一网络切片实例共享网络功能的其他网络切片实例是否允许增加或删除该第一网络功能。因此，在确定了该第一网络功能为共享网络功能的情况下，该NSM&O可以先确定与该第一网络切片实例共享网络功能的至少一个第二网络切片实例，并确定该第二网络切片实例是否允许增加或删除该第一网络功能，根据实际情况进行第一网络功能的配置。The NSM&O can also first determine whether the first network function is a shared network function or a dedicated network function. If the first network function is a dedicated network function, that is, only the first network slice instance is served, the NSM&O can directly determine the configuration that needs to perform the first network function. If the first network function is a shared network function, the NSM&O needs to consider whether other network slice instances sharing the network function with the first network slice instance are allowed to add or delete the first network function. Therefore, in the case that the first network function is determined to be a shared network function, the NSM&O may first determine at least one second network slice instance that shares the network function with the first network slice instance, and determine the second network slice instance. Whether the first network function is allowed to be added or deleted, and the configuration of the first network function is performed according to actual conditions.
综上所述，增加第一网络功能的具体实施方式可以分为下列几种情况：In summary, the specific implementation manner of adding the first network function can be divided into the following situations:
(1)该第一网络功能为共享网络功能，且所有第二网络切片实例均允许增加该第一网络功能，则该NSM&O可以直接为所有第二网络切片实例配置该第一网络功能。(1) The first network function is a shared network function, and all the second network slice instances allow the first network function to be added, and the NSM&O can directly configure the first network function for all the second network slice instances.
(2)该第一网络功能为共享网络功能，且第二网络切片实例一部分网络切片实例允许增加第一网络功能，另一部分网络切片实例不允许，则该NSM&O可以仅对允许增加第一网络功能的这一部分第二网络切片实例配置该第一网络功能。(2) The first network function is a shared network function, and a part of the network slice instance of the second network slice instance is allowed to increase the first network function, and another part of the network slice instance is not allowed, the NSM&O may only allow the first network function to be added. This portion of the second network slice instance configures the first network function.
(3)该第一网络功能为专属网络功能，或者该第一网络功能为共享网络功能，但全部第二网络切片实例不允许增加该第一网络功能，这两种情况下，该NSM&O可以仅为该第一网络切片实例配置第一网络功能。(3) The first network function is a dedicated network function, or the first network function is a shared network function, but all the second network slice instances are not allowed to increase the first network function. In both cases, the NSM&O may only The first network function is configured for the first network slice instance.
删除第一网络功能的具体实施方式可以分为下列几种情况：The specific implementation of deleting the first network function can be divided into the following cases:
(1)该第一网络功能为共享网络功能，且所有第二网络切片实例均允许删除该第一网络功能，则该NSM&O可以直接为所有第二网络切片实例配置该第一网络功能。(1) The first network function is a shared network function, and all the second network slice instances are allowed to delete the first network function, and the NSM&O can directly configure the first network function for all the second network slice instances.
(2)该第一网络功能为共享网络功能，且第二网络切片实例一部分网络切片实例允许删除第一网络功能，另一部分网络切片实例不允许，则该NSM&O可以仅对允许删除第一网络功能的这一部分第二网络切片实例配置该第一网络功能，对于不允许删除第一网络功能的那部分网络切片实例，仍然采用第一网络功能为其提供服务。(2) The first network function is a shared network function, and a part of the network slice instance of the second network slice instance is allowed to delete the first network function, and another part of the network slice instance is not allowed, the NSM&O may only allow deletion of the first network function. The second network slice instance of the portion configures the first network function, and the part of the network slice instance that is not allowed to delete the first network function is still served by the first network function.
(3)该第一网络功能为专属网络功能，或者该第一网络功能为共享网络功能，但全部第二网络切片实例不允许删除该第一网络功能，这两种情况下，该NSM&O可以仅为该第一网络切片实例配置第一网络功能。(3) The first network function is a dedicated network function, or the first network function is a shared network function, but all the second network slice instances are not allowed to delete the first network function. In both cases, the NSM&O may only The first network function is configured for the first network slice instance.
应理解，对于该第一网络功能为共享网络功能的情况，还可以有其他不同的实现方式，例如，若至少一个第二网络切片实例不允许增加或删除第一网络功能，该NSM&O可以直接向发送端返回更新响应消息，用于表示更新失败；或者在全部第二网络切片实例不允许增加或删除第一网络功能时，向发送端返回更新响应消息，用于表示更新失败，本发明实施例对此不作限定。It should be understood that, in the case that the first network function is a shared network function, there may be other different implementation manners. For example, if at least one second network slice instance does not allow the first network function to be added or deleted, the NSM&O may directly The sending end returns an update response message, which is used to indicate that the update fails. When the second network slice instance does not allow the first network function to be added or deleted, the update response message is returned to the sender to indicate that the update fails. This is not limited.
作为一个可选的实施例，在该NSM&O向EM发送配置请求消息之前，该方法还包括：该NSM&O确定该第一网络切片实例和/或全部或部分第二网络切片实例中是否存在依赖于该第一网络功能的第二网络功能；若存在该第二网络功能，该NSM&O向该EM、NFVO以及VIM中的至少一个发送修改请求消息，该修改请求消息用于请求修改该第二网络功能。As an optional embodiment, before the NSM&O sends the configuration request message to the EM, the method further includes: determining, by the NSM&O, whether the first network slice instance and/or all or part of the second network slice instance are dependent on the a second network function of the first network function; if the second network function exists, the NSM&O sends a modification request message to at least one of the EM, the NFVO, and the VIM, the modification request message being used to request to modify the second network function.
应理解，网络功能之间可能存在依赖性。关于依赖性，可以源网络功能和目标网络功能的方式来定义，例如，目标网络功能依赖于源网络功能，即目标网络功能部署时，源网络功能一定存在。增加或删除第一网络功能后，需要判断是否与其依赖的其它网络功能是否需要进行相应的配置修改。It should be understood that there may be dependencies between network functions. Regarding dependencies, the source network function and the target network function can be defined. For example, the target network function depends on the source network function, that is, when the target network function is deployed, the source network function must exist. After adding or deleting the first network function, you need to determine whether the corresponding network functions that you depend on need to be modified accordingly.
具体地，在本发明实施例中，该NSM&O可以先确定该第一网络切片实例和/或全部或部分第二网络切片实例中是否存在依赖于该第一网络功能的第二网络功能，若存在，则该NSM&O可以对该第二网络功能进行修改，避免第一网络功能的增加或删除对该第二网络功能产生影响。Specifically, in the embodiment of the present invention, the NSM&O may first determine whether there is a second network function that depends on the first network function in the first network slice instance and/or all or part of the second network slice instance, if yes, The NSM&O can modify the second network function to prevent the addition or deletion of the first network function from affecting the second network function.
具体地，若存在该第二网络功能，该NSM&O向该EM、NFVO以及VIM中的至少一个发送该修改请求消息。Specifically, if the second network function exists, the NSM&O sends the modification request message to at least one of the EM, NFVO, and VIM.

Optionally, the query request message may carry the identifier of the sending end. Correspondingly, the storage device receives the query request message. The storage device performs an inquiry and sends a query response message to the NSM&O, where the query response message is used to indicate whether the update request message is legal. Correspondingly, the NSM&O receives the query response message. The NSM&O sends a configuration request message to the EM, including: when the update request message is valid, the NSM&O sends the configuration request message to the EM.
具体地，由于在创建网络切片实例时，或用户初始化时，该存储设备会存储用户的相关签约信息以及网络切片实例与用户之间的对应关系。因此，在收到发送端发送的更新请求消息之前，该NSM&O可以先向存储设备发送查询请求消息，查询该更新请求消息是否合法，在该更新请求消息合法的情况下，该NSM&O再向该EM发送配置请求消息。Specifically, the storage device stores the related subscription information of the user and the correspondence between the network slice instance and the user, when the network slice instance is created, or when the user initializes. Therefore, before receiving the update request message sent by the sender, the NSM&O may first send a query request message to the storage device to check whether the update request message is legal. If the update request message is legal, the NSM&O redirects to the EM. Send a configuration request message.
这样，能够避免不合法的用户对网络切片实例的恶意更新，提高对网络切片实例管理的安全性。In this way, the malicious update of the network slice instance by the illegal user can be avoided, and the security of the network slice instance management is improved.

The updated information of the first network slice instance may include which network functions the first network slice instance specifically includes and the dependencies between the network functions. Optionally, the update notification message may also carry all or part of the updated information of the second network slice instance. Correspondingly, the storage device receives the update notification message. The storage device stores the update information of the first network slice instance and/or all or part of the second network slice instance, and sends a storage success message to the NSM&O. Correspondingly, the NSM&O receives the storage success message.
作为一个可选的实施例，在该NSM&O向EM发送配置请求消息之前，该方法还包括：该NSM&O向NM发送通知请求消息，该通知请求消息用于通知将要配置该第一网络功能；对应地，该NM接收该通知请求消息，并根据该通知请求消息向该NSM&O发送通知响应消息；对应地，该NSM&O接收该通知响应消息。As an optional embodiment, before the NSM&O sends the configuration request message to the EM, the method further includes: the NSM&O sending a notification request message to the NM, where the notification request message is used to notify that the first network function is to be configured; The NM receives the notification request message, and sends a notification response message to the NSM&O according to the notification request message; correspondingly, the NSM&O receives the notification response message.
具体地，对于存在NM的管理架构，该NSM&O和该NM都可以管理物理网络功能和虚拟网络功能，因此，为了避免配置的冲突，NSM&O和NM之间需要协调。该NSM&O可以向NM发送通知请求消息，通知将要配置的网络功能，在收到NM反馈的通知响应消息之后再进行配置。Specifically, for the management architecture in which the NM exists, the NSM&O and the NM can manage physical network functions and virtual network functions. Therefore, in order to avoid configuration conflicts, coordination between NSM&O and NM is required. The NSM&O may send a notification request message to the NM to notify the network function to be configured, and then perform configuration after receiving the notification response message fed back by the NM.
作为一个可选的实施例，在该NSM&O接收该EM根据该配置请求消息发送的配置响应消息之后，该方法还包括：该NSM&O向NM发送网络功能配置信息，该网络功能配置信息携带该第一网络功能的配置参数。As an optional embodiment, after the NSM&O receives the configuration response message sent by the EM according to the configuration request message, the method further includes: the NSM&O sending network function configuration information to the NM, where the network function configuration information carries the first Configuration parameters for the network function.
具体地，在NSM&O对第一网络功能配置完毕之后，该NSM&O可以向NM发送携带第一网络功能的配置参数的网络功能配置信息，以便于NM获知该NSM&O进行了哪些修改。Specifically, after NSM&O configures the first network function, the NSM&O may send network function configuration information that carries the configuration parameters of the first network function to the NM, so that the NM knows which modifications are made by the NSM&O.
