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 of different network slices and the network functions that make up them may be different.

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系统创建，一个网管系统可能创建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 sharding instance can be created by the network management system. A network management system may create multiple network shard instances and manage them at the same time, including performance monitoring and fault management during network snippet instance running. 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是能够提供完整的端到端的网络服务的，而组成网络切片实例的可以是子网络切片实例(Sub-Network slice instance)和/或网络功能。其中子网络切片实例可以不需要提供端到端的完整的网络服务，子网络切片实例可以是网络切片实例中同一个设备商的网络功能组成集合，也可能是按域划分的网络功能的集合，例如核心网子网络切片实例、接入网子网络切片实例。子网络切片实例可能被多个网络切片实例共享。提出子网络切片实例，可以方便网管系统管理。一个网络切片实例可能由若干子网络切片实例组成，每个子网络切片实例由若干网络功能组成；一个网络切片实例可能由若干子网络切片实例和没有被划分为子网络切片实例的网络功能组成；一个网络切片实例也可能仅由若干网络功能组成。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 sharding instance can provide complete end-to-end network services, and the network sharding instances can be sub-network slice instances and/or network functions. The sub-network slicing instance may not need to provide a complete network service end-to-end. The sub-network slicing instance may be a network function component set of the same device vendor in the network slicing instance, or may be a set of network functions divided by domain, for example, The core network sub-network snippet instance and the access network sub-network snippet instance. A subnet slice instance may be shared by multiple network slice instances. A sub-network slice instance is proposed to facilitate network management system management. A network slice instance may consist of several sub-network slice instances, each sub-network slice instance consisting of several network functions; a network slice instance may consist of several sub-network slice instances and network functions that are not divided into sub-network slice instances; A network slice instance may also consist of only a few network functions. 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.

可选地，一个网络切片实例可能同时提供多个服务。例如，运营商使用一个网络切片实例为水务公司提供抄水表业务，为电力公司提供抄电表业务。如有需求，可对不同服务的管理数据进行隔离，包括性能数据，故障信息等。当一个网络切片实例提供多个服务时，网络管理系统可以为每个服务实例分配一个身份标识，并且使该网络切片实例的网络功能和/或子网络切片实例感知各服务实例。Alternatively, one network tile instance may provide multiple services simultaneously. For example, operators use a network slicing instance to provide water companies with water metering services and power meter companies to provide meter reading services. If required, the management data of different services can be isolated, including performance data and fault information. When a network slice instance provides multiple services, the network management system can assign an identity to each service instance and make the network function and/or sub-network slice instance of the network slice instance aware of each service instance.

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 reached.

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1A中的网络管理架构。图1A示 出了一种网络管理架构100。该网络管理架构100包括三个层次，分别是网络管理系统(Network Management System，简称NMS)、网元管理系统(Element Management System，简称EMS)和网元(Network Element，简称NE)。EMS与NE之间有接口，可以相互通信。EMS与NMS之间有接口，可以相互通信。EMS与NMS之间的接口可以是Itf-N接口。当然，该接口也可能有其他名称。In order to facilitate the understanding of the embodiments of the present invention, the network management architecture in FIG. 1A is first introduced. Figure 1A shows a network management architecture 100. The network management architecture 100 includes three layers, namely, a network management system (NMS), an element management system (EMS), and a network element (NE). There is an interface between the EMS and the NE, which can communicate with each other. There is an interface between the EMS and the NMS, which can communicate with each other. The interface between the EMS and the NMS can be an Itf-N interface. Of course, the interface may have other names as well.

NMS可以包括一个或多个网络管理器，其主要提供网络管理功能，可以管理不同地域、不同设备供应商的网络，网络管理员可以通过NMS对网络进行全面的监控。NMS可提供网络管理的基本功能。例如：故障(Fault)、配置(Configuration)、计费(Accounting)、性能(Performance)和安全(Security)管理。The NMS can include one or more network managers, which mainly provide network management functions, can manage networks of different regions and different device vendors, and the network administrator can comprehensively monitor the network through the NMS. NMS provides the basic functions of network management. For example: Fault, Configuration, Accounting, Performance, and Security Management.

EMS可以包含网元管理器(element manager，简称EM)和/或域管理器(Domain Manager，简称DM)。其中，EM是用于管理网元的网络模块，其可以设置在网元上也可以单独设置。DM是比EM的管理范围更大一级的管理系统模块。DM可以管理一个或多个EM，例如，DM可以是厂商的管理系统。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是管理一个属于设备商(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。但本发明实施例中不排除DM执行EM所执行的流程的可能性。EM可以单独设置，图1A示意了这种情形。也可能设置在某个NE上，图1B示意了这种情形。The EMS may include an element manager (EM) and/or a domain manager (DM). The EM is a network module for managing network elements, and may be set on the network element or separately. The DM is a management system module that is one level larger than the management scope of the EM. The DM can manage one or more EMs, for example, the DM can be a vendor's management system. 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 a network equipment belonging to the equipment vendor (English: vendor). For domain management functions, DM has a larger scope than EM. Typically, EM devices are used to perform configuration of network functions. However, the possibility that the DM performs the process performed by the EM is not excluded in the embodiment of the present invention. The EM can be set separately, as illustrated in Figure 1A. It may also be set on a certain NE, which is illustrated in Figure 1B.

NE可以是物理网络功能(Physical network function,PNF)模块和/或虚拟网络功能(Virtualized network function,VNF)模块。物理网络功能(Physical network function,PNF)模块是一个物理设备提供固定的网络功能。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)，也就是说一个物理网元。NE可以是接入网设备或核心网设备。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。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。The NE may be a physical network function (PNF) module and/or a virtualized network function (VNF) module. The Physical Network Function (PNF) module is a physical device that provides fixed network functionality. 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. The NE can be an access network device or a core network device. For example, the NE may be a base station, a Mobility Management Entity (MME), or a Serving Gateway (SGW). The Virtualized Network Function (VNF) module can be the smallest virtual unit that can be monitored and managed in the network management architecture.

网络切片实例可以在NE上实现。网络切片实例由NMS创建，一个NMS可能创建一个或多个网络切片实例并对它们进行管理。一个网络切片实例可能由若干子网络切片实例组成，每个子网络切片实例由若干网络功能组成；一个网络切片实例也可能由若干子网络切片实例和没有被划分为子网络切片实例的网络功能组成；一个网络切片实例还有可能仅由若干网络功能组成。无线接入网可能切片化，也可能不切片化。在图1A中，无线接入网不切片化，网络切片实例1和网络切片实例2共享无线接入网。在图1B中，无线接入网切片化，网络切片实例1和网络切片实例2分别包括不同的无线接入网部分的切片实例。A network slice instance can be implemented on the NE. Network slice instances are created by the NMS, and an NMS may create and manage one or more network slice instances. A network slice instance may be composed of several sub-network slice instances, each sub-network slice instance consisting of several network functions; one network slice instance may also be composed of several sub-network slice instances and network functions that are not divided into sub-network slice instances; It is also possible for a network slice instance to consist of only a few network functions. The radio access network may or may not be sliced. In FIG. 1A, the radio access network is not sliced, and the network slice instance 1 and the network slice instance 2 share the radio access network. In FIG. 1B, the radio access network is sliced, and network slice instance 1 and network slice instance 2 respectively include slice instances of different radio access network portions.

当多个网络切片实例共存时，网络切片实例之间可能完全隔离，也有可能 共享部分网络资源和功能，针对多网络切片实例共存，给出了两种场景：组别A(Group A)和组别(Group B)，分别如图2和图3所示。图2示出了本发明一个实施例的网络切片实例的示意性结构框图，在图2中，网络切片实例1和切片实例2共享无线接入网(英文：Radio Access Network，简写：RAN)，网络切片实例1包括无线接入网和核心网切片实例1(也可以称为核心网子网络切片实例1)。网络切片实例2包括无线接入网和核心网切片实例2(也可以称为核心网子网络切片实例2)。核心网切片实例1和核心网切片实例2在逻辑上完全隔离。图3示出了本发明另一个实施例的网络切片实例的示意性结构框图，在图3中，核心网切片实例1和核心网切片实例2之间有部分共享的控制面功能，称为共享的核心网控制面网络功能(英文：Common Control Plane Network Function，简写：common CP NF)，每个网络切片实例还有专属的核心网控制面网络功能(英文：Common Control Plane Network Function，简写：slice-specificCP NF)和专属的核心网用户面网络功能(英文：Slice-specific User Plane Network Function，简写：slice-specific UP NF)。网络切片实例1包括无线接入网、共享的核心网控制面网络功能、专属的核心网控制面网络功能1和专属的核心网用户面网络功能1。网络切片实例2包括无线接入网、共享的核心网控制面网络功能、专属的核心网控制面网络功能2和专属的核心网用户面网络功能2。值得注意的是，无线接入网也可以切片化，无线接入网可以包括在逻辑上完全隔离的接入网的网络切片实例，或者无线接入网的网络切片实例之间也可以有部分共享的网络功能。而且，当无线接入网包括在逻辑上完全隔离的接入网的网络切片实例时，核心网可以包括在逻辑上完全隔离的核心网切片实例或者核心网切片实例可以有部分共享的网络功能。当无线接入网的网络切片实例之间有部分共享的网络功能时，核心网可以包括在逻辑上完全隔离的核心网切片实例或者核心网切片实例可以有部分共享的网络功能。When multiple network slice instances coexist, the network slice instances may be completely isolated, and some network resources and functions may be shared. For the coexistence of multiple network slice instances, two scenarios are given: Group A and Group (B), as shown in Figure 2 and Figure 3, respectively. 2 is a schematic structural block diagram of an example of a network slice according to an embodiment of the present invention. In FIG. 2, a network access instance 1 and a slice instance 2 share a radio access network (English: Radio Access Network, abbreviated as RAN). The network slice instance 1 includes a radio access network and a core network slice instance 1 (which may also be referred to as a core network sub-network slice instance 1). The network slice instance 2 includes a radio access network and a core network slice instance 2 (which may also be referred to as a core network sub-network slice instance 2). Core network slice instance 1 and core network slice instance 2 are logically completely isolated. FIG. 3 is a schematic structural block diagram of a network slice instance according to another embodiment of the present invention. In FIG. 3, a core shared network slice instance 1 and a core network slice instance 2 have a partially shared control plane function, which is called sharing. The core network control plane network function (English: Common Control Plane Network Function, abbreviated: common CP NF), each network slice instance also has a dedicated core network control plane network function (English: Common Control Plane Network Function, abbreviated: slice -specificCP NF) and exclusive core-specific User Plane Network Function (slice-specific User Plane Network Function, abbreviated: slice-specific UP NF). The network slice instance 1 includes a radio access network, a shared core network control plane network function, a dedicated core network control plane network function 1 and a dedicated core network user plane network function 1. The network slice instance 2 includes a radio access network, a shared core network control plane network function, a dedicated core network control plane network function 2, and a dedicated core network user plane network function 2 . It should be noted that the radio access network may also be sliced, the radio access network may include a network slice instance of the access network that is logically completely isolated, or the network slice instances of the radio access network may also be partially shared. Network function. Moreover, when the radio access network includes a network slice instance of a logically fully isolated access network, the core network may include a core network slice instance that is logically completely isolated or a core network slice instance may have a partially shared network function. When there is a partially shared network function between network slice instances of the radio access network, the core network may include a core network slice instance that is logically completely isolated or a core network slice instance may have a partially shared network function.

本发明实施例在网络管理架构100的基础上，在NMS中引入了网络切片管理与编排(Network slice manager and orchestrator，简称为“NSM&O”)模块。NSM&O模块可以设置在某个NM上，也可以单独设置。On the basis of the network management architecture 100, the network slice manager and orchestrator ("NSM&O") module is introduced in the NMS. The NSM&O module can be set to an NM or it can be set separately.

其中NSM&O模块的结构示意图如图4所示，其主要功能包括监测，用于检测和报告网络切片实例的性能信息和故障信息等。The structure diagram of the NSM&O module is shown in Figure 4. Its main functions include monitoring, which is used to detect and report performance information and fault information of network slice instances.

NSM&O模块的主要功能还包括以下任一项：The main functions of the NSM&O module also include any of the following:

服务转换：通过接口，例如，应用程序编程接口(Application Programming Interface，简称为“API”)，接收发送端设备发送的服务描述信息，并将服务描述信息转换为对网络的需求。Service conversion: Receives service description information sent by the sender device through an interface, for example, an Application Programming Interface (API), and translates the service description information into a network requirement.

网络切片管理：根据设计好的策略，对网络切片的生命周期进行管理。例如，可以是网络切片实例化、网络切片实例缩放、网络切片实例更新、网络切片实例终结、网络切片删除等。Network Slice Management: Manage the life cycle of network slices according to a well-designed strategy. For example, it may be network slice instantiation, network slice instance scaling, network slice instance update, network slice instance termination, network slice deletion, and the like.

网络切片编排：用于具体确定网络切片实例所包含的网络功能和使用的网络资源。Network Slice Orchestration: Used to specifically determine the network functions and network resources used by the network slice instance.

上述发送端设备是向NSM&O模块发送请求的设备。例如，发送端设备可以是运营商、第三方客户、通信业务涉及的应用或其他任意可能向NSM&O发送请求的实体设备。The above-mentioned sender device is a device that sends a request to the NSM&O module. For example, the sender device may be an operator, a third party client, an application involved in the communication service, or any other physical device that may send a request to the NSM&O.

图5示出了本发明实施例提供的网络管理方法，该方法可以应用于图1A和图1B所示的网络架构，也可能应用于其他网络架构。例如应用于如下网络架构：网络管理系统用于管理网络切片实例，网络管理系统可以包括一个或多个网络管理器。网元管理系统可以包括EM和/或DM。网络切片实例包括多个网络功能和/或多个子网络切片。本发明实施例的网络管理方法对网络架构并不作限定。如图5所示，该方法包括如下步骤：FIG. 5 illustrates a network management method provided by an embodiment of the present invention. The method may be applied to the network architecture shown in FIG. 1A and FIG. 1B, and may also be applied to other network architectures. For example, it is applied to a network architecture: a network management system for managing network slice instances, and a network management system may include one or more network managers. The element management system may include EM and/or DM. A network slice instance includes multiple network functions and/or multiple sub-network tiles. The network management method in the embodiment of the present invention does not limit the network architecture. As shown in FIG. 5, the method includes the following steps:

501、网络管理系统向网元管理系统发送配置告警信息的请求，网元管理系统相应接收配置告警信息的请求。所述配置告警信息的请求包括对应网络切片实例的告警信息的参数。501. The network management system sends a request for configuring the alarm information to the network element management system, and the network element management system receives the request for configuring the alarm information. The request for configuring the alarm information includes parameters of the alarm information corresponding to the network slice instance.

告警信息是指当网元管理系统中的EM和/或DM收到其所管理的网络功能和/或子网络切片实例的故障报告后，需要生成的告警信息(AlarmInformation)，该告警信息可以存入EM和/或DM的告警列表(AlarmList)中。AlarmInformation是一个含有一项或多项参数的集合，每项参数可能有一个或多个元素，各元素的值有不同的确定方法(例如，计算方法)。告警信息的参数可以包括下面中的一个或多个：故障严重性(PerceivedSeverity)参数、故障趋势(trendIndication)参数、故障阈值(thresholdInfo)参数、被监视属性(monitoredAttributes)参数和提议的修复动作(proposedRepairActions)参数。这些参数可以包括一个或多个元素，各个元素可以有不同的确定方法(例如，计算方法)。PerceivedSeverity参数用于标示故障的紧急情况。PerceivedSeverity参数可以包括元素，该元素的值可以是极重要(Critical)、重要(Major)、次要(Minor)、警告(Warning)、不确定的(Indeterminate)和清除了的(Cleared)等。trendIndication参数用于标示故障情况正在变好，变坏或没有变化。thresholdInfo参数用于通知EMS需要监视的指标的标识、以及指标对应的阈值。EMS上报告警信息时，可以上报越过阈值的性能指标的标识、阈值设定值和越过阈值的观测值。monitoredAttributes参数用于标示变化的被监视的属性。提议的修复动作参数用于表明EMS提议的修复动作。以上五个参数仅是举例，本发明实施例不限定于仅配置上述参数，告警信息的参数也可能包括其他参数。上述告警信息的参数都是对应网络切片实例的。当网元管理系统收到所管理的网络功能和/或子网络切片实例的故障报告后，将根据该故障报告确定对应网络切片实例的告警信息。The alarm information refers to the alarm information (AlarmInformation) that needs to be generated after the EM and/or DM in the NE management system receives the fault report of the network function and/or the sub-network snippet instance managed by the MME. Enter the alarm list (AlarmList) of the EM and/or DM. AlarmInformation is a collection of one or more parameters. Each parameter may have one or more elements, and the values of each element have different determination methods (for example, calculation methods). The parameters of the alarm information may include one or more of the following: Persived Severity parameter, trend indication parameter, failure threshold parameter, monitored attribute parameter, and proposed repair action (proposedRepairActions) )parameter. These parameters may include one or more elements, each of which may have a different determination method (eg, a calculation method). The PerceivedSeverity parameter is used to indicate the emergency of the fault. The PerceivedSeverity parameter can include an element whose value can be Critical, Major, Minor, Warning, Indeterminate, and Cleared. The trendIndication parameter is used to indicate that the fault condition is getting better, worse or not changing. The thresholdInfo parameter is used to notify the identifier of the indicator that the EMS needs to monitor, and the threshold corresponding to the indicator. When the alarm information is reported on the EMS, the identifier of the performance indicator that crosses the threshold, the threshold set value, and the observation value that exceeds the threshold may be reported. The monitoredAttributes parameter is used to indicate the monitored attributes of the change. The proposed repair action parameter is used to indicate the repair action proposed by the EMS. The above five parameters are only examples. The embodiment of the present invention is not limited to only configuring the above parameters, and the parameters of the alarm information may also include other parameters. The parameters of the above alarm information are all corresponding to the network slice instance. After receiving the fault report of the managed network function and/or the sub-network slice instance, the network element management system determines the alarm information of the corresponding network slice instance according to the fault report.

在网元管理系统所管理的网络功能和/或子网络切片实例是某个特定网络切片实例专属的情况下，则步骤501中配置告警信息的请求所包括的告警信息的参数就是该特定网络切片实例的告警信息的参数。可选地，配置告警信息的 请求中还可以包括该特定网络切片实例的标识信息。该特定网络切片实例的标识信息可以参数的形式体现，也可以元素的形式体现。例如，当告警信息的参数包括附加信息(additionalText)时，也可增加网络切片实例的标识信息的元素。In the case that the network function and/or the sub-network slice instance managed by the network element management system is specific to a specific network slice instance, the parameter of the alarm information included in the request for configuring the alarm information in step 501 is the specific network slice. The parameters of the alarm information of the instance. Optionally, the request for configuring the alarm information may further include identifier information of the specific network slice instance. The identification information of the specific network slice instance may be embodied in the form of a parameter or in the form of an element. For example, when the parameter of the alarm information includes additional information (additionalText), the element of the identification information of the network slice instance may also be added.

在网元管理系统所管理的网络功能和/或子网络切片实例是至少两个网络切片实例之间共享的情况下，则步骤501中配置告警信息的请求所包括的告警信息的参数就是对应该至少两个网络切片实例的告警信息的参数。相应地，配置告警信息的请求中可以包括该至少两个网络切片实例的标识信息以及分别对应该至少两个网络切片实例的告警信息的参数。该至少两个网络切片实例的标识信息可以参数的形式体现，也可以元素的形式体现。例如，当告警信息的参数包括附加信息(additionalText)时，也可增加该至少两个网络切片实例的标识信息的元素。对于告警信息的参数，也可以包括至少两个元素，以体现出该至少两个网络切片实例的告警信息。例如，对于PerceivedSeverity参数，其可以包括多个元素，每个元素可以取的值是Critical,Major,Minor,Warning,Indeterminate,Cleared等。每个元素和一个网络切片实例对应，表明该故障对该网络切片实例的影响。网络功能或子网络切片实例上发生相同的故障对不同网络切片实例的影响可能不同。可选地，告警信息的参数还可包括故障对不同网络切片实例服务的影响的确定方法，例如元素的值的计算方法。对于trendIndication参数，其也可以包括多个元素，每个元素的取值代表了相应的网络切片实例的情况正在变好，变坏或没有变化。对于thresholdInfo参数，其也可以包括多组元素，每组元素的取值分别代表了相应的网络切片实例的监视的越过阈值的性能指标的标识、阈值设定值和越过阈值的观测值。各组元素中，阈值设定值、监视的越过阈值的性能指标的标识可能都不相同，也可能相同。对于monitoredAttributes参数，其也可以包括多个元素，每个元素的取值代表了相应的网络切片实例的希望监视的属性，这些元素的值可能相同，也可能不同。对于proposedRepairActions参数，其也可以包括多个元素，代表不同网络切片实例所希望的修复策略。例如，抄电表和抄危险化学品存储温度感应器的两个网络切片实例共用同一网络功能或子网络切片实例时，当该网络功能或子网络切片实例发生故障后，前者不要求立即修复，后者可能要求立即使用备份网络功能或备份子网络切片实例，等发生故障的网络功能或子网络切片实例修复后再切换回来。以上参数仅是举例，本发明不限定于仅配置上述参数。In the case that the network function and/or the sub-network slice instance managed by the network element management system is shared between at least two network slice instances, the parameter of the alarm information included in the request for configuring the alarm information in step 501 is corresponding. The parameters of the alarm information of at least two network slice instances. Correspondingly, the request for configuring the alarm information may include the identifier information of the at least two network slice instances and the parameters corresponding to the alarm information of the at least two network slice instances. The identification information of the at least two network slice instances may be embodied in the form of parameters or in the form of elements. For example, when the parameter of the alarm information includes additional information (additionalText), the elements of the identification information of the at least two network slice instances may also be increased. For the parameter of the alarm information, at least two elements may also be included to reflect the alarm information of the at least two network slice instances. For example, for the PerceivedSeverity parameter, it can include multiple elements, each of which can take values of Critical, Major, Minor, Warning, Indeterminate, Cleared, and the like. Each element corresponds to a network slice instance, indicating the impact of the failure on the network slice instance. The same failure on a network function or sub-network slice instance may have different effects on different network slice instances. Optionally, the parameters of the alert information may also include a method of determining the impact of the fault on different network slice instance services, such as a method of calculating the value of the element. For the trendIndication parameter, it may also include multiple elements, and the value of each element represents that the situation of the corresponding network slice instance is getting better, worse or no change. For the thresholdInfo parameter, it may also include multiple sets of elements, and the values of each set of elements respectively represent the identifier of the performance indicator that exceeds the threshold monitored by the corresponding network slice instance, the threshold set value, and the observed value that crosses the threshold. Among the group elements, the threshold setting value and the monitored performance index of the threshold exceeding the threshold may be different or the same. For the monitoredAttributes parameter, it can also include multiple elements. The value of each element represents the attributes of the corresponding network slice instance that you want to monitor. The values of these elements may be the same or different. For the proposedRepairActions parameter, it can also include multiple elements that represent the desired repair strategy for different network slice instances. For example, when two network slice instances of the meter and the hazardous chemicals storage temperature sensor share the same network function or sub-network slice instance, when the network function or the sub-network slice instance fails, the former does not require immediate repair, and then You may be asked to immediately use the backup network function or backup subnet snippet instance, and then switch back after the failed network function or subnet shard instance is fixed. The above parameters are merely examples, and the present invention is not limited to the configuration of only the above parameters.

网络切片实例的标识信息可能有多种形式，例如标识信息为数字，或由网络切片实例的类型和切片实例的专属特性(Slice Differentiator,简称SD)组成的标识，本发明不做限定。该至少两个网络切片实例的告警信息的参数可以相同也可以不同。在告警信息的参数中包括网络切片实例的标识信息，可以通过在告警信息中增加参数的形式实现，该参数即是网络切片实例的标识信息；或者可以通过在原有参数中增加元素的形式实现，该元素即是网络切片实例的标识信息。例如，若告警信息的参数中包括附加信息(additionalText) 参数，则可增加一个元素，即网络切片实例的标识信息。The identification information of the network sharding instance may be in a plurality of forms, for example, the identification information is a number, or an identifier consisting of a type of the network sharding instance and a singular instance (Slice Differentiator, SD for short), which is not limited by the present invention. The parameters of the alarm information of the at least two network slice instances may be the same or different. The parameter of the network segment instance is included in the parameter of the alarm information, which may be implemented by adding a parameter in the alarm information, where the parameter is the identifier information of the network slice instance, or may be implemented by adding an element in the original parameter. This element is the identification information of the network slice instance. For example, if the parameter of the alarm information includes an additional information (additionalText) parameter, an element may be added, that is, the identification information of the network slice instance.

触发步骤501的原因可能有多种，下面通过举例的方式进行说明。一种情形可能是：EMS向网络管理系统发送了告警配置请求，网络管理系统相应接收了该告警配置请求。所述告警配置请求用于请求所述网络管理系统向所述网元管理系统发送配置告警信息的请求。这种情形可能发生在EM和/或DM重启等情况下。另一种情形可能是发生了网络功能和/或子网络切片实例的创建和初始化配置。所述网络功能和/或子网络切片实例的创建和初始化配置可以发生在以下情况中：i)网络切片实例化；ii)网络切片实例扩展且增加网络功能/子网络切片实例；或iii)网络切片实例更新且新建网络功能/子网络切片实例取代原有网络功能/子网络切片实例。该网络功能和/或子网络切片实例可能是至少两个网络切片实例共享的网络功能和/或子网络切片实例，也可能是某网络切片实例专属的网络功能和/或子网络切片实例。There may be many reasons for triggering step 501, which will be described below by way of example. One scenario may be that the EMS sends an alert configuration request to the network management system, and the network management system accordingly receives the alert configuration request. The alarm configuration request is used to request the network management system to send a request for configuring alarm information to the network element management system. This situation may occur in situations such as EM and/or DM restarts. Another situation may be the creation and initial configuration of network functions and/or sub-network tile instances. The creation and initial configuration of the network function and/or sub-network slice instance may occur in the following cases: i) network slice instantiation; ii) network slice instance extension and addition of network function/sub-network slice instance; or iii) network The slice instance is updated and the new network function/subnetwork slice instance replaces the original network function/subnetwork slice instance. The network function and/or sub-network slice instance may be a network function and/or a sub-network slice instance shared by at least two network slice instances, or may be a network function and/or a sub-network slice instance specific to a network slice instance.

502、EMS根据配置告警信息的请求，配置告警信息的参数。具体地，EMS配置对应网络切片实例的告警信息的参数，502. The EMS configures parameters of the alarm information according to the request for configuring the alarm information. Specifically, the EMS configures parameters of the alarm information corresponding to the network slice instance,

503、EMS向网络管理系统发送告警信息配置确认，网络管理系统相应接收告警信息配置确认。告警信息配置确认可以用于标示EMS已完成告警信息配置。503. The EMS sends an alarm information configuration confirmation to the network management system, and the network management system receives the alarm information configuration confirmation accordingly. The alarm information configuration confirmation can be used to indicate that the EMS has completed alarm information configuration.

通过步骤501-503，可以完成告警信息的配置。使网络功能和/或子网络切片实例在发生故障时，网元管理系统能生成符合要求的故障告警信息，以便于网络管理系统能从告警信息中分析出故障对网络切片实例的服务的影响。对专属的网络功能和/或子网络切片实例，网络管理系统能从告警信息中知道故障对专属的网络功能/子网络切片实例的影响。对共享的网络功能和/或子网络切片实例，网络管理系统能分辨故障对各个网络切片实例的不同影响，从而帮助运营商能更快定位故障原因，聚焦关键故障，保障关键服务。Through the steps 501-503, the configuration of the alarm information can be completed. When the network function and/or the sub-network slicing instance are faulty, the network element management system can generate the fault alarm information that meets the requirements, so that the network management system can analyze the impact of the fault on the service of the network slicing instance from the alarm information. For proprietary network functions and/or sub-network slice instances, the network management system can know from the alarm information the impact of the failure on the dedicated network function/sub-network slice instance. For shared network functions and/or sub-network slicing instances, the network management system can distinguish the different impacts of faults on individual network slicing instances, helping operators to locate faults faster, focus on critical faults, and secure critical services.

504、当EMS所管理的网络功能和/或子网络切片实例发生故障时，网络功能和/或子网络切片实例上报故障报告给管理它的EMS。该故障报告中可以包含故障的具体信息。该故障可能是硬件故障、软件故障、网络功能故障、过载、通信链路中断、或虚拟化相关故障等。504. When the network function and/or the sub-network slice instance managed by the EMS fails, the network function and/or the sub-network slice instance reports a fault report to the EMS that manages it. The fault report can contain specific information about the fault. The failure may be a hardware failure, a software failure, a network function failure, an overload, a communication link interruption, or a virtualization related failure.

505、EMS收到故障报告后，分析故障报告中的故障对使用该网络功能和/或子网络切片实例的网络切片实例上运行的服务的影响，并按照配置告警信息的请求中的告警信息参数配置生成相应告警信息(AlarmInformation)，存入告警列表(AlarmList)中。505. After receiving the fault report, the EMS analyzes the impact of the fault in the fault report on the service running on the network slice instance using the network function and/or the sub-network slicing instance, and according to the alarm information parameter in the request for configuring the alarm information. Configure the corresponding alarm information (AlarmInformation) and store it in the alarm list (AlarmList).

可选地，上述网络管理方法还可能包括如下步骤：Optionally, the foregoing network management method may further include the following steps:

506、网络管理系统向网元管理系统发送告警信息配置修改通知，网元管理系统相应接收告警信息配置修改通知。所述告警信息配置修改通知包括告警信息的参数的调整，告警信息的参数的调整是对应网络切片实例的。506. The network management system sends an alarm information configuration modification notification to the network element management system, and the network element management system receives the alarm information configuration modification notification accordingly. The alarm information configuration modification notification includes adjustment of the parameter of the alarm information, and the adjustment of the parameter of the alarm information is corresponding to the network slice instance.

网络功能和/或子网络切片实例的扩展、收缩、更新会触发对应网络切片实例的告警信息配置的调整。网络功能和/或子网络切片实例的扩展可以发生在网络切片实例扩展时，具体来说，扩展网络功能和/或子网络切片实例包括扩展其计算资源、存储资源、网络资源。网络功能和/或子网络切片实例的收 缩可以发生在网络切片实例收缩时，具体来说，收缩网络功能和/或子网络切片实例包括收缩其计算资源、存储资源、网络资源。网络功能和/或子网络切片实例的更新可以发生在网络切片实例更新时，具体来说，更新网络功能和/或子网络切片实例包括更新其软件版本。The expansion, contraction, and update of the network function and/or the sub-network slice instance triggers the adjustment of the alarm information configuration of the corresponding network slice instance. An extension of the network function and/or sub-network tile instance may occur when the network slice instance is extended, in particular, the extended network function and/or the sub-network slice instance includes extending its computing resources, storage resources, network resources. The shrinking of network functions and/or sub-network slice instances can occur when the network slice instance shrinks, specifically, the shrink network function and/or the sub-network slice instance includes shrinking its computing resources, storage resources, network resources. Updates to network functions and/or sub-network tile instances may occur when a network tile instance is updated, specifically, updating network functions and/or sub-network tile instances includes updating their software versions.

网络功能和/或子网络切片实例扩展/收缩/更新后，考虑故障对其所对应的网络切片实例的影响，网络管理系统可以向管理该网络功能和/或子网络切片实例的EMS发送告警信息配置修改通知。告警信息配置修改通知包括以下至少一项：调整PerceivedSeverity参数中对应网络切片实例的取值方法；调整thresholdInfo参数中对应网络切片实例的需要监视的指标的标识、或指标对应的阈值；调整对应网络切片实例的monitoredAttributes的监视的值；调整proposedRepairActions中对应网络切片实例的对故障的修复动作；调整trendIndication中对应网络切片实例的对变化趋势的评价标准等。本发明不限于仅对上述参数调整，也有可能对其他参数进行调整。网络功能和/或子网络切片实例扩展、收缩、更新后，相同的故障对其服务的影响可能不同。通过告警信息配置修改通知，可以更好地体现故障对因网络功能和/或子网络切片实例的扩展、收缩、更新造成的变化后的网络切片实例的影响。After the network function and/or sub-network slice instance expansion/shrink/update, considering the impact of the fault on its corresponding network slice instance, the network management system may send an alert message to the EMS managing the network function and/or the sub-network slice instance. Configure modification notifications. The alarm information configuration modification notification includes at least one of the following: adjusting the value of the corresponding network slice instance in the PerceivedSeverity parameter; adjusting the identifier of the indicator to be monitored corresponding to the network slice instance in the thresholdInfo parameter, or the threshold corresponding to the indicator; adjusting the corresponding network slice The monitored value of the monitored attribute of the instance; adjusts the fault repairing action of the corresponding network slice instance in the proposedRepairActions; adjusts the evaluation criteria of the corresponding trend of the network slice instance in the trendIndication. The present invention is not limited to only adjusting the above parameters, and it is also possible to adjust other parameters. After the network function and/or sub-network slice instance is extended, contracted, and updated, the same failure may have different impacts on its services. By configuring the modification notification by the alarm information, the impact of the failure on the network slice instance caused by the expansion, contraction, and update of the network function and/or the sub-network slice instance can be better reflected.

当新创建一个网络切片实例需要使用已存在的网络功能和/或子网络切片实例时，需要对该网络功能和/或子网络切片实例进行配置，使之为所述网络切片实例提供服务。该配置会触发网络管理系统向管理该网络功能和/或子网络切片实例的EMS发送告警信息配置修改通知。该告警信息配置修改通知包括：在告警信息的参数中增加元素来标示新创建的网络切片实例。例如，在PerceivedSeverity参数中增加元素，该元素用于标示故障对于新创建的网络切片实例的影响程度；在thresholdInfo参数中增加元素，该元素表明针对新创建的网络切片实例的监视的超过阈值的性能指标的标识、阈值、具体性能指标的值；在trendIndication参数中增加元素，该元素用于标示故障对于新创建的网络切片实例的影响变化情况；在monitoredAttributes参数中增加元素，该元素用于标示新创建网络切片实例需要监视变化的参数；proposedRepairActions参数中增加元素，该元素用于标示新创建的网络切片实例采取的修复方法。上面仅是举例说明，可能在上述参数中的一个或多个中增加对应新创建的网络切片实例的元素。还可能包括在其他参数中增加对应新创建的网络切片实例的元素，例如在网络切片实例的标识信息中增加元素，该元素用于标示新创建的网络切片实例。通过告警信息配置修改通知，可以在后续EMS上报的告警信息中体现故障对于新创建的网络切片实例的服务的影响。When a new network slice instance needs to be used to use an existing network function and/or a sub-network slice instance, the network function and/or the sub-network slice instance needs to be configured to serve the network slice instance. This configuration triggers the network management system to send an alert information configuration modification notification to the EMS that manages the network function and/or the sub-network slice instance. The alarm information configuration modification notification includes: adding an element to the parameter of the alarm information to indicate the newly created network slice instance. For example, add an element to the PerceivedSeverity parameter that indicates how much the fault affects the newly created network slice instance; add an element to the thresholdInfo parameter that indicates the performance of the monitored threshold for the newly created network slice instance. The identifier, threshold, and value of the specific performance indicator; add an element to the trendIndication parameter, which is used to indicate the impact of the fault on the newly created network slice instance; add an element in the monitoredAttributes parameter, which is used to mark the new Creating a network slice instance requires monitoring the changed parameters; an element is added to the proposedRepairActions parameter, which is used to indicate the repair method taken by the newly created network slice instance. The above is only an example, and it is possible to add an element corresponding to the newly created network slice instance in one or more of the above parameters. It may also include adding elements corresponding to the newly created network slice instance to other parameters, such as adding an element in the identification information of the network slice instance, which is used to mark the newly created network slice instance. You can use the alarm information to configure the modification notification to reflect the impact of the fault on the service of the newly created network slice instance in the alarm information reported by the subsequent EMS.

当一个网络切片实例使用了共享网络功能和/或子网络切片实例，且这个网络切片实例终结时，不能终结共享网络功能和/或子网络切片实例，而是需要对该共享网络功能和/或子网络切片实例进行配置，终结它和所述网络切片实例的关系。该配置会触发网络管理系统向管理该网络功能和/或子网络切片实例的EMS发送告警信息配置修改通知。该告警信息配置修改通知包括：在告警信息的参数中删除用于标示被终结的网络切片实例的元素。例如：在 PerceivedSeverity参数中删除元素，该元素标示了故障对于被终结的网络切片实例的影响程度；在thresholdInfo参数中删除元素，该元素标示了被终结的网络切片实例的监视的超过阈值的性能指标的标识、阈值、具体性能指标的值；在trendIndication参数中增删除元素，该元素标示了故障对于被终结的网络切片实例的影响变化情况；在monitoredAttributes参数中删除元素，该元素标示了被终结的网络切片实例需要监视变化的参数；proposedRepairActions参数中删除元素，该元素标示了被终结的网络切片实例采取的修复方法。上面仅是举例说明，可能在上述参数中的一个或多个中删除对应被终结的网络切片实例的元素。还可能包括在其他参数中删除对应被终结的网络切片实例的元素，例如在网络切片实例的标识信息中删除元素，该元素用于标示被终结的网络切片实例。通过告警信息配置修改通知，可以在后续EMS上报的告警信息中不再体现故障对于被终结的网络切片实例的服务的影响。When a network slice instance uses a shared network function and/or a sub-network slice instance, and the network slice instance terminates, the shared network function and/or the sub-network slice instance cannot be terminated, but the shared network function and/or The subnet slice instance is configured to terminate its relationship with the network slice instance. This configuration triggers the network management system to send an alert information configuration modification notification to the EMS that manages the network function and/or the sub-network slice instance. The alarm information configuration modification notification includes: deleting an element for indicating the terminated network slice instance in the parameter of the alarm information. For example, the element is deleted in the PerceivedSeverity parameter, which indicates the degree of impact of the failure on the terminated network slice instance; the element is deleted in the thresholdInfo parameter, which indicates the performance of the monitored network slice instance that exceeds the threshold. The value of the identifier, threshold, and specific performance indicator; add and delete elements in the trendIndication parameter, which indicates the change of the impact of the fault on the terminated network slice instance; delete the element in the monitoredAttributes parameter, which indicates the terminated The network slice instance needs to monitor the changed parameters; the deletedRepairActions parameter deletes the element, which indicates the repair method taken by the terminated network slice instance. The above is only an example, and elements corresponding to the terminated network slice instance may be deleted in one or more of the above parameters. It may also include deleting the element corresponding to the terminated network slice instance in other parameters, for example, deleting the element in the identification information of the network slice instance, and the element is used to indicate the terminated network slice instance. By configuring the modification notification of the alarm information, the impact of the fault on the service of the terminated network slice instance is no longer reflected in the alarm information reported by the subsequent EMS.

507、EMS根据告警信息配置修改通知，修改告警信息的参数的配置。507. The EMS configures a modification notification according to the alarm information, and modifies the configuration of the parameter of the alarm information.

508、EMS向网络管理系统发送告警信息配置修改确认，网络管理系统相应接收告警信息配置修改确认。所述告警信息配置修改确认用于指示EMS根据所述告警信息配置修改请求进行了网络切片实例的告警信息的参数的配置修改。508. The EMS sends an alarm information configuration modification confirmation to the network management system, and the network management system receives the alarm information configuration modification confirmation accordingly. The alarm information configuration modification confirmation is used to instruct the EMS to perform configuration modification of the parameter of the network slice instance alarm information according to the alarm information configuration modification request.

可选地，在步骤508之后还可能重新进行步骤504和505。Optionally, steps 504 and 505 may also be performed again after step 508.

通过告警信息配置修改通知，可以调整告警信息的参数，有益于EMS根据网络功能和/或子网络切片实例的故障报告反馈出网络功能和/或子网络切片实例对其现在服务的网络切片实例的影响。By configuring the modification notification by the alarm information, the parameters of the alarm information can be adjusted, which is beneficial for the EMS to feed back the network function and/or the sub-network slice instance according to the network function and/or the sub-network slice instance fault report. influences.

图6示出了本发明实施例提供的另一种网络管理方法。如图6所示，该网络管理方法可以包括如下步骤：FIG. 6 shows another network management method provided by an embodiment of the present invention. As shown in FIG. 6, the network management method may include the following steps:

601、网络管理系统向EMS发送获取告警数量(getAlarmCount)请求。相应地，EMS接收该请求。getAlarmCount请求用于请求获取对应网络切片实例的告警数量。对应网络切片实例的告警数量是指对应网络切片实例的符合所述告警信息参数的告警数量。601. The network management system sends a request for obtaining an alarm quantity (getAlarmCount) to the EMS. Accordingly, the EMS receives the request. The getAlarmCount request is used to request the number of alarms for the corresponding network slice instance. The number of alarms corresponding to the network segment instance refers to the number of alarms corresponding to the alarm information parameter of the corresponding network slice instance.

602、EMS向网络管理系统发送告警数量回复。相应地，网络管理系统接收该告警数量回复。该告警数量回复中包括对应所述网络切片实例的告警数量。602. The EMS sends an alarm quantity reply to the network management system. Correspondingly, the network management system receives the alarm number reply. The alarm quantity reply includes the number of alarms corresponding to the network slice instance.

步骤601中的getAlarmCount请求还可以包括对应网络切片实例的告警数量过滤(filter)条件，其作用是过滤对服务影响较小的故障告警或运营商不关注的故障告警或关联故障的告警等。相应地，在步骤602中EMS仅上报符合告警数量过滤条件的告警数量。The getAlarmCount request in the step 601 may further include an alarm quantity filter condition corresponding to the network slice instance, and the function is to filter the fault alarm that has less impact on the service or the fault alarm or the associated fault alarm that the operator does not pay attention to. Correspondingly, in step 602, the EMS reports only the number of alarms that meet the alarm quantity filtering condition.

在网元管理系统所管理的网络功能和/或子网络切片实例是某个特定网络切片实例专属的情况下，步骤601中的告警数量过滤条件是该特定网络切片实例的告警数量过滤条件。相应地，在步骤602中EMS仅上报符合告警数量过滤条件的该特定网络切片实例的告警数量。In the case that the network function and/or the sub-network slice instance managed by the network element management system is specific to a specific network slice instance, the alarm quantity filtering condition in step 601 is the alarm quantity filtering condition of the specific network slice instance. Correspondingly, in step 602, the EMS reports only the number of alarms of the specific network slice instance that meets the alarm quantity filtering condition.

在网元管理系统所管理的网络功能和/或子网络切片实例是至少两个网络切片实例之间共享的情况下，步骤601中告警数量过滤条件是该至少两个网络 切片实例的分别告警数量过滤条件。该至少两个网络切片实例分别的告警数量过滤条件可以相同也可以不同。相应地，在步骤602中EMS上报分别符合该至少两个网络切片实例的告警数量过滤条件的至少两个网络切片实例的告警数量。例如，网络切片实例A和网络切片实例B共享一个网络功能或子网络切片实例，则步骤601中可以包括网络切片实例A的告警数量过滤条件和网络切片实例B的告警数量过滤条件。相应地，EMS可以初始化两个计数器，并逐条判断各AlarmInformation是否满足网络切片实例A和网络切片实例B的过滤条件，若某AlarmInformation满足网络切片实例A的条件，并不满足网络切片实例B的条件，则网络切片实例A对应的计数器加一，网络切片实例B对应的计数器不加。最后，EMS获取了网络切片实例A和网络切片实例B的告警数量并添加网络切片实例的身份标识后上报给网络管理系统。当某网络切片实例的告警数量过滤条件配置为全过滤时，则EMS不上报该网络切片实例的告警数。In the case that the network function and/or the sub-network splicing instance managed by the network element management system is shared between the at least two network splicing instances, the alarm quantity filtering condition in step 601 is the number of alarms of the at least two network snippet instances. Filter conditions. The alarm number filtering conditions of the at least two network slice instances may be the same or different. Correspondingly, in step 602, the EMS reports the number of alarms of at least two network slice instances that respectively meet the alarm quantity filtering conditions of the at least two network slice instances. For example, the network slice instance A and the network slice instance B share one network function or a sub-network slice instance, and the step 601 may include the alarm number filtering condition of the network slice instance A and the alarm quantity filtering condition of the network slice instance B. Correspondingly, the EMS can initialize two counters and determine whether each AlarmInformation satisfies the filtering conditions of the network slice instance A and the network slice instance B one by one. If an AlarmInformation satisfies the condition of the network slice instance A, the condition of the network slice instance B is not satisfied. Then, the counter corresponding to the network slice instance A is incremented by one, and the counter corresponding to the network slice instance B is not added. Finally, the EMS obtains the number of alarms of the network slice instance A and the network slice instance B and adds the identity of the network slice instance to the network management system. The EMS does not report the number of alarms of the network segment instance when the number of alarms in the network segment is set to be filtered.

getAlarmCount请求中包括对应网络切片实例的告警数量过滤条件，使网络管理系统能依据故障对各网络切片实例的不同影响，灵活获取所需的对应网络切片实例的告警数量，聚焦对网络切片实例服务产生较大影响的故障，但也不会丢失其他信息，有利于后续故障修复。而且，在网元管理系统所管理的网络功能和/或子网络切片实例是至少两个网络切片实例之间共享的情况下，步骤601中告警数量过滤条件是该至少两个网络切片实例的告警数量过滤条件。这使得网络管理系统可以区分该网络功能和/或子网络切片实例对不同网络切片实例的影响，分别获取不同网络切片实例的符合告警参数过滤条件的告警信息。The getAlarmCount request includes the alarm quantity filtering condition of the corresponding network snippet instance, so that the network management system can flexibly obtain the required number of alarms of the corresponding network sharding instance according to the different impacts of the fault on each network sharding instance, and focus on the network snippet instance service generation. A large impact of the failure, but will not lose other information, which is conducive to subsequent failure repair. Moreover, in the case that the network function and/or the sub-network splicing instance managed by the network element management system is shared between the at least two network splicing instances, the alarm quantity filtering condition in step 601 is an alarm of the at least two network snippet instances. Quantity filter conditions. This allows the network management system to distinguish the impact of the network function and/or the sub-network splicing instance on different network snippet instances, and obtain the alarm information of the different network snippet instances that meet the filtering parameters of the alarm parameters.

该网络管理方法还可以包括如下步骤：The network management method may further include the following steps:

603、网络管理系统向EMS发送获取告警列表(getAlarmList)请求。相应地，EMS接收该请求。getAlarmList请求用于请求获取对应网络切片实例的告警列表中告警信息。603. The network management system sends a request for obtaining an alert list (getAlarmList) to the EMS. Accordingly, the EMS receives the request. The getAlarmList request is used to request to obtain the alarm information in the alarm list of the corresponding network slice instance.

604、EMS向网络管理系统发送告警信息。相应地，网络管理系统接收该告警信息。该告警信息的形式可能是告警列表，该告警列表中包括对应网络切片实例的符合告警信息参数的告警信息。604. The EMS sends an alarm message to the network management system. Correspondingly, the network management system receives the alert information. The alarm information may be in the form of an alarm list, and the alarm list includes alarm information corresponding to the alarm information parameter of the network slice instance.

步骤603中的getAlarmList请求还可以包括告警信息过滤(filter)条件，该告警信息过滤(filter)条件是对应网络切片实例的，其作用是过滤对服务影响较小的故障告警或运营商不关注的故障告警或关联故障的告警等。相应地，在步骤604中EMS上报的告警列表包括对应网络切片实例的符合告警信息过滤条件的告警信息。The getAlarmList request in step 603 may further include an alarm information filter condition, where the filter condition is corresponding to the network slice instance, and the function is to filter the fault alarm that has little impact on the service or the operator does not pay attention to Fault alarm or associated fault alarm. Correspondingly, the alarm list reported by the EMS in step 604 includes the alarm information corresponding to the filtering condition of the alarm information corresponding to the network slice instance.

在网元管理系统所管理的网络功能和/或子网络切片实例是某个特定网络切片实例专属的情况下，步骤603中的告警信息过滤条件是该特定网络切片实例的告警信息过滤条件。相应地，在步骤604中EMS仅上报符合告警信息过滤条件的该特定网络切片实例的告警信息。In the case that the network function and/or the sub-network slice instance managed by the network element management system is specific to a specific network slice instance, the alarm information filtering condition in step 603 is the alarm information filtering condition of the specific network slice instance. Correspondingly, in step 604, the EMS only reports the alarm information of the specific network slice instance that meets the filtering condition of the alarm information.

在网元管理系统所管理的网络功能和/或子网络切片实例是至少两个网络切片实例之间共享的情况下，步骤603中告警信息过滤条件是该至少两个网络 切片实例的告警信息过滤(filter)条件。该至少两个网络切片实例分别的告警信息过滤条件可以相同也可以不同。相应地，在步骤604中EMS上报分别符合该至少两个网络切片实例的告警信息过滤条件的至少两个网络切片实例的告警信息。EMS会针对各条AlarmInformation，判断其是否符合各网络切片实例的告警信息的过滤条件，最后上报的各AlarmInformation中，仅含有满足告警信息过滤条件的对应的网络切片实例的身份标识和相关参数中对应的元素，可以包括PerceivedSeverity，trendIndication，threshold，monitoredAttributes，proposedRepairActions或其他参数。例如网络切片实例A和网络切片实例B的一个共享网络功能发生故障，该故障对网络切片实例A和网络切片实例B的服务造成的影响不同，生成的告警信息满足网络切片实例A的告警信息过滤条件，而不满足网络切片实例B的告警信息过滤条件，则上报的告警信息中仅含有网络切片实例A的标识和参数中相应的元素。In the case that the network function and/or the sub-network splicing instance managed by the network element management system is shared between the at least two network splicing instances, the alarm information filtering condition in step 603 is that the alarm information filtering of the at least two network snippet instances is (filter) conditions. The alarm information filtering conditions of the at least two network slice instances may be the same or different. Correspondingly, in step 604, the EMS reports alarm information of at least two network slice instances that respectively meet the alarm information filtering conditions of the at least two network slice instances. The EMS will determine whether it meets the filtering conditions of the alarm information of each network slice instance for each AlarmInformation. The last reported AlarmInformation only contains the corresponding identifiers of the corresponding network slice instance that meet the filtering conditions of the alarm information and the corresponding parameters. Elements, which can include PerceivedSeverity, trendIndication, threshold, monitoredAttributes,posedRepairActions or other parameters. For example, a shared network function of the network splicing instance A and the network splicing instance B has a different impact on the service of the network splicing instance A and the network splicing instance B. The generated alarm information meets the alarm information filtering of the network splicing instance A. If the condition does not satisfy the alarm information filtering condition of the network slice instance B, the reported alarm information only includes the identifier of the network slice instance A and the corresponding element in the parameter.

getAlarmList请求中包括对应网络切片实例的告警信息过滤条件，使网络管理系统能依据故障对各网络切片实例的不同影响，灵活获取所需的对应网络切片实例的告警信息，聚焦对网络切片实例服务产生较大影响的故障，但也不会丢失其他信息，有利于后续故障修复。而且，在网元管理系统所管理的网络功能和/或子网络切片实例是至少两个网络切片实例之间共享的情况下，步骤603中告警信息过滤条件是该至少两个网络切片实例的告警信息过滤条件。这使得网络管理系统可以区分该网络功能和/或子网络切片实例对不同网络切片实例的影响，分别获取不同网络切片实例的符合告警信息过滤条件的告警信息。The getAlarmList request includes the alarm information filtering condition of the corresponding network snippet instance, so that the network management system can flexibly obtain the required alarm information of the corresponding network sharding instance according to the different impacts of the fault on each network sharding instance, and focus on the network snippet instance service generation. A large impact of the failure, but will not lose other information, which is conducive to subsequent failure repair. Moreover, in the case that the network function and/or the sub-network slice instance managed by the network element management system is shared between the at least two network slice instances, the alarm information filtering condition in step 603 is an alarm of the at least two network slice instances. Information filtering conditions. This allows the network management system to distinguish the impact of the network function and/or the sub-network splicing instance on the different network snippet instances, and obtain the alarm information of the different network snippet instances that meet the filtering conditions of the alarm information.

步骤603与604可以采取同步模式，即EMS收到getAlarmList请求后就即时根据目前EMS内存储的AlarmList上报对应网络切片实例的告警列表。Steps 603 and 604 can take the synchronization mode, that is, the EMS receives the getAlarmList request and immediately reports the alarm list of the corresponding network slice instance according to the AlarmList stored in the current EMS.

步骤603与604还可以采取异步模式，即EMS收到getAlarmList请求后不根据目前EMS内存储的AlarmList上报对应网络切片实例的告警列表，而是等收到其所管理的网络功能和/或子网络切片发送的故障报告后更新AlarmList后，才上报对应网络切片实例的告警列表。这种情形下，上述网络管理方法在步骤603与604之间还可以包括如下步骤：Steps 603 and 604 may also adopt an asynchronous mode, that is, after receiving the getAlarmList request, the EMS does not report the alarm list of the corresponding network slice instance according to the AlarmList stored in the current EMS, but waits for the network function and/or the sub-network managed by the EMS. After the alarm report is sent, the alarm list is updated, and the alarm list of the corresponding network segment instance is reported. In this case, the network management method may further include the following steps between steps 603 and 604:

605、当EMS所管理的网络功能和/或子网络切片实例发生故障时，网络功能和/或子网络切片实例上报故障报告给管理它的EMS。605. When the network function and/or the sub-network slice instance managed by the EMS fails, the network function and/or the sub-network slice instance reports the fault report to the EMS that manages it.

606、EMS收到故障报告后，分析故障报告中的故障对使用该网络功能和/或子网络切片实例的网络切片实例上运行的服务的影响，并按照配置告警信息的请求中的告警信息参数配置生成相应告警信息(AlarmInformation)，存入告警列表(AlarmList)中。606. After receiving the fault report, the EMS analyzes the impact of the fault in the fault report on the service running on the network slice instance using the network function and/or the sub-network slicing instance, and according to the alarm information parameter in the request for configuring the alarm information. Configure the corresponding alarm information (AlarmInformation) and store it in the alarm list (AlarmList).

图5所示的管理方法可以拓展到对一个网络切片实例上的不同服务实例进行管理，实现对网络切片实例的服务实例进行告警信息的配置以及告警信息的配置修改。The management method shown in Figure 5 can be extended to manage different service instances on a network sharding instance to implement the configuration of alarm information and configuration modification of alarm information for the service instance of the network snippet instance.

步骤506中的告警信息的参数的调整是对应网络切片实例的服务实例。具体来说，当在网络切片实例上新创建服务实例时，会触发网络管理系统向对应 的EMS发送告警信息配置修改通知。该告警信息配置修改通知包括：在告警信息的参数中增加用于标示新创建的服务实例的元素。例如，在PerceivedSeverity参数中增加元素，该元素标示了故障对于新创建的服务实例的影响程度；在thresholdInfo参数中增加元素，该元素表明针对新创建的服务实例的监视的超过阈值的性能指标的标识、阈值、具体性能指标的值；在trendIndication参数中增加元素，该元素用于标示故障对于新创建的服务实例的影响变化情况；在monitoredAttributes参数中增加元素，该元素用于标示对于新创建的服务实例需要监视变化的参数；proposedRepairActions参数中增加元素，该元素用于标示新创建的服务实例采取的修复方法。上面仅是举例说明，可能在上述参数中的一个或多个中增加对应新创建的服务实例的元素，还可能包括在其他参数中增加对应新创建的服务实例的元素。通过告警信息配置修改通知，可以在后续EMS上报的告警信息中体现故障对于新创建的服务实例的服务的影响。The adjustment of the parameter of the alarm information in step 506 is a service instance corresponding to the network slice instance. Specifically, when a service instance is newly created on the network slice instance, the network management system is triggered to send an alarm information configuration modification notification to the corresponding EMS. The alarm information configuration modification notification includes: adding an element for indicating the newly created service instance to the parameter of the alarm information. For example, an element is added to the PerceivedSeverity parameter that indicates the extent to which the failure affects the newly created service instance; an element is added to the thresholdInfo parameter that indicates the identity of the performance metric that exceeds the threshold for monitoring of the newly created service instance. , threshold, value of the specific performance indicator; add an element in the trendIndication parameter, which is used to indicate the impact of the failure on the newly created service instance; add an element in the monitoredAttributes parameter, which is used to indicate the newly created service The instance needs to monitor the changed parameters; the raisedRepairActions parameter adds an element that identifies the repair method taken by the newly created service instance. The above is only an example. It is possible to add an element corresponding to the newly created service instance in one or more of the above parameters, and may also include adding an element corresponding to the newly created service instance among other parameters. You can use the alarm information to configure the modification notification to reflect the impact of the fault on the service of the newly created service instance in the alarm information reported by the subsequent EMS.

当在网络切片实例上调整服务实例时，会触发网络管理系统向对应的EMS发送告警信息配置修改通知。该告警信息配置修改通知包括以下至少一项：调整PerceivedSeverity中故障对服务实例的影响程度评判条件；调整thresholdInfo参数中对应服务实例需要监视的指标的标识、或指标对应的阈值；调整monitoredAttributes该服务实例的监视的值；调整proposedRepairActions中对针对该服务实例的故障修复动作；调整trendIndication中故障对于服务实例的变化趋势的评价标准。本发明不限于仅对所述参数调整，也有可能对其他参数进行调整。网络功能和/或子网络切片实例扩展、收缩、更新后，相同的故障对其服务的影响可能不同。通过告警信息配置修改通知，可以更好地体现故障对因网络功能和/或子网络切片实例的扩展、收缩、更新造成的变化后的网络切片实例的影响。调整服务实例包括调整服务实例的资源使用策略，例如调整该服务实例使用的网络资源、计算资源、或存储资源等。When the service instance is adjusted on the network slice instance, the network management system is triggered to send an alarm information configuration modification notification to the corresponding EMS. The alarm information configuration modification notification includes at least one of the following: adjusting the impact condition of the impact of the fault on the service instance in the PerseivedSeverity; adjusting the identifier of the indicator to be monitored by the corresponding service instance in the thresholdInfo parameter, or the threshold corresponding to the indicator; adjusting the monitored attribute to the service instance The value of the monitoring; adjust the fault repair action for the service instance in the proposedRepairActions; adjust the evaluation criteria of the fault trend of the service instance in the trendIndication. The invention is not limited to only adjusting the parameters, and it is also possible to adjust other parameters. After the network function and/or sub-network slice instance is extended, contracted, and updated, the same failure may have different impacts on its services. By configuring the modification notification by the alarm information, the impact of the failure on the network slice instance caused by the expansion, contraction, and update of the network function and/or the sub-network slice instance can be better reflected. Adjusting a service instance includes adjusting a resource usage policy of the service instance, such as adjusting network resources, computing resources, or storage resources used by the service instance.

当在网络切片实例上终结服务实例，会触发网络管理系统向对应的EMS发送告警信息配置修改通知。该告警信息配置修改通知包括：在告警信息的参数中删除用于标示被终结的服务实例的元素。例如：在PerceivedSeverity参数中删除元素，该元素标示了故障对于被终结的服务实例的影响程度；在thresholdInfo参数中删除元素，该元素标示了针对被终结的服务实例的监视的超过阈值的性能指标的标识、阈值、具体性能指标的值；在trendIndication参数中删除元素，该元素标示了故障对于被终结的服务实例的影响变化情况；在monitoredAttributes参数中删除元素，该元素标示了被终结的服务实例需要监视变化的参数；proposedRepairActions参数中删除元素，该元素标示了对于被终结的服务实例采取的修复方法。上面仅是举例说明，可能在上述参数中的一个或多个中删除对应被终结的服务实例的元素，还可能包括在其他参数中删除对应被终结的服务实例的元素。通过告警信息配置修改通知，可以在后续EMS上报的告警信息中不再体现故障对于被终结的服务实例的服务的影响。When the service instance is terminated on the network splicing instance, the network management system is triggered to send an alarm information configuration modification notification to the corresponding EMS. The alarm information configuration modification notification includes: deleting an element for indicating the terminated service instance in the parameter of the alarm information. For example, the element is deleted in the PerceivedSeverity parameter, which indicates the degree of impact of the failure on the service instance being terminated; the element is deleted in the thresholdInfo parameter, which indicates the performance index of the threshold exceeding the threshold for the monitored service instance. The value of the identifier, threshold, and specific performance indicator; delete the element in the trendIndication parameter, which indicates the change of the impact of the fault on the terminated service instance; delete the element in the monitoredAttributes parameter, which indicates the required service instance needs to be terminated. Monitor the changed parameters; remove the element in the proposedRepairActions parameter, which identifies the fix for the terminated service instance. The above is only an example. It is possible to delete the element corresponding to the terminated service instance in one or more of the above parameters, and may also include deleting the element corresponding to the terminated service instance among other parameters. By configuring the modification notification of the alarm information, the impact of the fault on the service of the terminated service instance is no longer reflected in the alarm information reported by the subsequent EMS.

步骤505中，EMS收到故障报告后，会分析故障报告中的故障对使用该网络功能和/或子网络切片实例的网络切片实例上运行的服务实例的影响，并按照告警信息参数配置生成相应告警信息，存入告警列表中。In step 505, after receiving the fault report, the EMS analyzes the impact of the fault in the fault report on the service instance running on the network slice instance using the network function and/or the sub-network slicing instance, and generates corresponding information according to the alarm information parameter configuration. The alarm information is stored in the alarm list.

当网络切片实例上的服务实例变化(如新建、调整或终结)时，告警信息能体现故障对变化后的网络切片实例的服务实例的影响。可以使网络管理系统能够从上报的告警信息中分辨故障对不同服务实例的影响。When the service instance on the network segment instance changes (such as creating, adjusting, or terminating), the alarm information can reflect the impact of the fault on the service instance of the changed network slice instance. The network management system can distinguish the impact of the fault on different service instances from the reported alarm information.

图6所示的管理方法可以拓展到对一个网络切片实例上的不同服务实例的管理，可以获取对应网络切片实例的服务实例的告警数量和告警列表。这种情形下，步骤601中的getAlarmCount请求是用于请求获取对应网络切片实例的服务实例的告警数量。对应网络切片实例的服务实例告警数量是指对应网络切片实例的服务实例的符合所述告警信息参数的告警数量。步骤602中EMS发送的告警数量是对应网络切片实例的服务实例的告警数量。The management method shown in FIG. 6 can be extended to the management of different service instances on a network sharding instance, and the number of alarms and the alarm list of the service instance corresponding to the network snippet instance can be obtained. In this case, the getAlarmCount request in step 601 is the number of alarms for requesting to obtain the service instance of the corresponding network slice instance. The number of service instance alarms corresponding to the network snippet instance refers to the number of alarms corresponding to the alarm information parameter of the service instance corresponding to the network sharding instance. The number of alarms sent by the EMS in step 602 is the number of alarms corresponding to the service instance of the network slice instance.

步骤601中的getAlarmCount请求还可以包括对应网络切片实例的服务实例的告警数量过滤(filter)条件。相应地，在步骤602中EMS仅上报符合对应网络切片实例的服务实例的告警数量过滤条件的告警数量。The getAlarmCount request in step 601 may further include an alert quantity filter condition of the service instance corresponding to the network slice instance. Correspondingly, in step 602, the EMS reports only the number of alarms that meet the alarm quantity filtering condition of the service instance of the corresponding network slice instance.

步骤603中的getAlarmList请求是用于请求对应网络切片实例的服务实例的告警列表。步骤604中EMS向网络管理系统发送的告警列表是对应网络切片实例的服务实例，该告警列表中包括对应网络切片实例的服务实例的告警信息。The getAlarmList request in step 603 is an alert list for requesting a service instance of the corresponding network slice instance. The alarm list sent by the EMS to the network management system in step 604 is a service instance corresponding to the network slice instance, and the alarm list includes the alarm information of the service instance corresponding to the network slice instance.

步骤603中的getAlarmList请求还可以包括对应网络切片实例的服务实例的告警信息过滤(filter)条件。相应地，步骤604中EMS仅上报符合告警信息过滤条件的该网络切片实例的服务实例的告警信息。The getAlarmList request in step 603 may further include an alert information filter condition corresponding to the service instance of the network slice instance. Correspondingly, in step 604, the EMS reports only the alarm information of the service instance of the network slice instance that meets the filtering condition of the alarm information.

The sub-network snippet instance of the network snippet instance can be configured with alarm information and configuration information of the alarm information. In this case, the request for configuring the alarm information in step 501 includes parameters of the alarm information of the sub-network slice instance corresponding to the network slice instance. In step 502, the EMS configures parameters of the alarm information corresponding to the sub-network slice instance of the network slice instance. In step 505, after receiving the fault report, the EMS analyzes the impact of the fault in the fault report on the sub-network slicing instance running on the network slicing instance using the network function and/or the sub-network slicing instance, and configures according to the alarm information parameter. Generate corresponding alarm information and save it in the alarm list. The adjustment of the parameters of the alarm information in step 506 is a sub-network slice instance corresponding to the network slice instance.

图6所示的管理方法可以拓展到对一个网络切片上的不同子网络切片实例，可以获取对应网络切片实例的子网络切片实例的告警数量和告警列表。这种情形下，步骤601中的getAlarmCount请求是用于请求获取对应网络切片实例的子网络切片实例的告警数量。对应网络切片实例的子网络切片实例告警数量是指对应网络切片实例的子网络切片实例的符合所述告警信息参数的告警数量。步骤602中EMS发送的告警数量是对应网络切片实例的子网络切片实例的告警数量。The management method shown in Figure 6 can be extended to different sub-network snippet instances on a network slice, and the number of alarms and alarm lists of sub-network snippet instances corresponding to the network snippet instance can be obtained. In this case, the getAlarmCount request in step 601 is the number of alarms for requesting to acquire the sub-network slice instance of the corresponding network slice instance. The number of alarms of the sub-network snippet instance corresponding to the network snippet instance refers to the number of alarms corresponding to the alarm information parameter of the sub-network snippet instance of the network snippet instance. The number of alarms sent by the EMS in step 602 is the number of alarms of the sub-network slice instance corresponding to the network slice instance.

步骤601中的getAlarmCount请求还可以包括对应网络切片实例的子网络 切片实例的告警数量过滤(filter)条件。相应地，在步骤602中EMS仅上报符合对应网络切片实例的子网络切片实例的告警数量过滤条件的告警数量。The getAlarmCount request in step 601 may also include an alert quantity filter condition for the sub-network slice instance of the corresponding network slice instance. Correspondingly, in step 602, the EMS reports only the number of alarms that match the alarm quantity filtering condition of the sub-network slice instance of the corresponding network slice instance.

步骤603中的getAlarmList请求是用于请求对应网络切片实例的子网络切片实例的告警列表。步骤604中EMS向网络管理系统发送的告警列表是对应网络切片实例的子网络切片实例，该告警列表中包括对应网络切片实例的子网络切片实例的告警信息。The getAlarmList request in step 603 is an alert list for requesting a sub-network slice instance of the corresponding network slice instance.
