具体实施方式
下面结合附图对本公开进行描述。
在介绍本公开实施例提供的方法和装置的之前，首先对涉及的部分名词进行解释。
在无线通讯***的管理领域，网络管理***(Network Management System，NMS)与网元管理***(Element Management System，EMS)之间的接口称为北向接口(Itf-N)。其中，EMS主要完成国际电信联盟(International Telecommunication Union，ITU)、电信管理网络(Telecommunications Management Network，TMN)中的网元管理层(Network Element Management Layer，EML)功能，即完成一个或多个移动通信设备的管理功能，通常不同设备供应商之间的EMS无法通用；而NMS主要完成ITU和TMN中的网络管理层(Network Management Layer，NML)功能，负责一个被管网络内所有网元的管理。
对于被管网络称为子网(SubNetwork，参见第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)技术规范(Technical Specification，TS)28.622)，如果存在多个设备供应商的情况，可以通过多个设备供应商各自的EMS管理达到管理整个子网的目的。
而在运营商的整个管理***中，一般还包含运营支撑***(Operations support system，OSS)、业务支撑***(Business support system，BSS)，从总体上看，一般认为NMS包含在OSS中，是OSS的一部分。
网络切片(Network Slice)是5G的一个组成部分。所谓网络切片，主要是指由一组网络功能(包含支持所述网络功能的网络资源)组成的具有特定的网 络特性的实例化的完整的逻辑网络，该逻辑网络用于满足某一类特定网络业务的需求，这里的网络特性的例子有超低延时和超高可靠性等。
而网络切片是根据网络切片蓝图进行实例化而获得，故也称网络切片实例。网络切片蓝图(模板实例)是指一个完整的定义，用于描述网络切片实例的结构、配置和工作流，网络切片管理功能模块(Network Slicing Management Function，NSMF)根据网络切片蓝图的定义完成网络切片的实例化及网络切片的生命周期的控制管理。
当一个网络切片比较复杂时，为了便于管理，网络切片可以分解为子切片，子切片是指一组网络功能及支持所述网络功能的网络资源组成的具有特定的网络特性的一个逻辑网络。一个网络切片可以包含0个、1个或多个子切片。对于子切片的管理和编排，由子切片管理功能(Network Slice Subnet Management Function，NSSMF)完成。NSSMF根据子切片蓝图的定义完成子切片的实例化及子切片的生命周期的控制管理。
如前所述，一个网络切片或子切片由一组(一个或多个)网络功能组成，而一个网络功能则可以只包含在一个网络切片或子切片，也可以包含在两个或多个网络切片或子切片中，这种场景下，这个网络功能被两个或多个网络切片或子切片所共享。
但在网络功能被共享的场景下，对网络切片、子切片和网络功能的管理会跟网络功能不共享的场景有所不同，比如，对于故障管理，当被共享的网络功能产生故障时，需要考虑所述故障对共享该网络功能的网络切片或子切片是否有影响，所以在相应的告警信息中需要包括受影响的网络切片或子切片的信息，同时在告警的处理上也需要考虑这个问题。
参见图1，本公开提出了一种网络告警方法，所述方法包括如下步骤。
步骤S1010，网络切片管理功能NSMF接收上报的告警信息，其中，所述告警信息包括网络切片的标识和/或子切片的标识。
其中，所述网络切片管理功能NSMF接收的告警信息是由网络功能NF、网络功能管理功能NFMF或子切片管理功能NSSMF所上报。
参见图2，5G的网络切片是为了特定的通讯服务提供支持，所以从整个5G 网络切片的管理来看，还包括通信服务管理功能(Common Single Mode Fiber，CSMF)，5G网络切片的管理分为三层：CSMF-NSMF-NSSMF。
第一种技术方案：网络切片的管理过程涉及CSMF、NSMF、NSSMF以及网络功能(Network Function，NF)，所以当NF发送故障时，告警信息的传递过程一般是NF-＞NSSMF-＞NSMF-＞CSMF，所以对于被共享的NF发生故障时，为了能将受影响的网络切片/子切片信息传递上去，一般的处理过程包括如下步骤。
在告警信息里，增加一个可选的字段“切片列表”(比如命名为受影响的切片列表(affectedSliceList))，用于当被共享的NF发生故障时记录受影响的网络切片和/或子切片的唯一标识(如标识(IDentifier，ID)等)。
当NF发生故障时，NF在生成一般的告警信息外，NF对故障进行分析，判断是否有网络切片和/或子切片受到所述故障的影响，若有，则将受影响的网络切片的标识和/或子切片的标识(如ID等)填入相应的告警信息的affectedSliceList字段；NF将告警上报给NSSMF。
NSSMF收到告警后，NSSMF可能会根据告警信息进行相应的管理操作，NSSMF对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的标识(如ID)填入相应的告警信息的affectedSliceList字段；NSSMF将告警上报给NSMF。
在一实施例中，在所述网络切片管理功能NSMF接收上报的告警信息之后，还包括：所述NSMF根据所述告警信息对受影响的网络切片和/或子切片进行相应的修复操作。
在一实施例中，NSMF根据收到的告警信息进行相应的管理操作，如故障的修复等，但并不以此为限。
第二种技术方案：NF直接将告警上报给NSMF，则步骤如下。
在告警信息里，增加一个可选的字段“切片列表”(比如命名为affectedSliceList)，用于当被共享的NF发生故障时记录受影响的网络切片和/ 或子切片的唯一标识(如ID等)。
当NF发生故障时，NF会生成一般的告警信息，并对故障进行分析，判断是否有网络切片和/或子切片受到所述故障的影响，若有，则将受影响的网络切片的标识和/或子切片的标识(如ID等)填入相应的告警信息的affectedSliceList字段；NF将告警上报给NSMF。
在一实施例中，所述NSMF接收上报的告警信息之后，还包括：所述NSMF根据所述告警信息对受影响的网络切片和/或子切片进行相应的修复操作。
在一实施例中，NSMF根据收到的告警信息对状态为共享网络中的受影响的网络切片和/或子切片进行相应的管理操作，如故障的修复等，但并不以此为限。
第三种技术方案：当NF是被NF管理功能(NF Management Function，NFMF)管理时，再通过NF管理功能NFMF被NSSMF管理，则告警处理过程的步骤如下。
在告警信息里，增加一个可选字段(比如命名为affectedSliceList)，用于当被共享的NF发生故障时记录受影响的网络切片和/或子切片的唯一标识(如ID等)。
当NF发生故障时，NF在生成一般的告警信息外，NF对故障进行分析，判断是否有网络切片和/或子切片受到所述故障的影响，若有，则将受影响的网络切片的标识和/或子切片的标识(如ID等)填入相应的告警信息的affectedSliceList字段；NF将故障信息上报给NF对应的NF管理功能NFMF；所述NF管理功能在生成相应的告警信息的时候，对故障进行分析，判断是否有网络切片和/或子切片受到所述故障的影响，若有，则将受影响的网络切片和/的标识或子切片的标识(如ID等)填入相应的告警信息的affectedSliceList字段；NF管理功能将告警上报给NSSMF；NSSMF收到告警后，可能会根据告警信息进行相应的管理操作，但NSSMF会对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的标识(如ID)填入相应的告警信息的affectedSliceList字段；NSSMF将告警上报给NSMF。
在一实施例中，在所述NSMF接收上报的告警信息之后，还包括：所述NSMF根据所述告警信息对受影响的网络切片和/或子切片进行相应的修复操作。
在一实施例中，NSMF根据收到的告警信息对状态为共享网络中的受影响的网络切片和/或子切片进行相应的管理操作，如故障的修复等，但并不以此为限。
第四种技术方案：NF管理功能NFMF将告警直接上报给NSMF，则步骤如下。
在告警信息里，增加一个可选字段(比如命名为affectedSliceList)，用于当被共享的NF发生故障时记录受影响的网络切片和/或子切片的唯一标识(如ID等)。
当NF发生故障时，NF在生成一般的告警信息外，NF对故障进行分析，判断是否有网络切片和/或子切片受到所述故障的影响，若有，则将受影响的网络切片的标识和/或子切片的标识(如ID等)填入相应的告警信息的affectedSliceList字段；NF将故障信息上报给NF对应的NF管理功能NFMF；所述NF管理功能NFMF对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的标识(如ID)填入相应的告警信息的affectedSliceList字段；NF管理功能NFMF将告警上报给NSMF。
在一实施例中，所述网络切片管理功能NSMF接收上报的告警信息之后，还包括：所述网络切片管理功能NSMF根据所述告警信息对受影响的网络切片和/或子切片进行相应的修复操作。
在一实施例中，NSMF根据收到的告警信息对受影响的网络切片和/或子切片进行相应的管理操作，如故障的修复等，但并不以此为限。
本实施例中，不管在第一情况(NF是否被共享，告警信息里都有切片列表(affectedSliceList)字段)，还是在第二种情况(只有在NF是被2个或多个网络切片或子切片共享时，在告警信息里才有切片列表(affectedSliceList)字段，若NF没有被共享，则告警信息中没有切片列表字段)下，网络告警的步骤流程 均跟上述任一技术方案的方法相同，在此不在赘述。
另外，本公开所述的网络切片和网络子切片，实际是指实例化后的网络切片和网络子切片，故也可以称为网络切片实例和网络子切片实例。
本公开提供的技术方案包括：网络切片管理功能NSMF接收上报的告警信息，其中，所述告警信息包括网络切片的标识和/或子切片的标识；所述网络切片管理功能NSMF接收的告警信息是由网络功能NF、网络功能管理功能NFMF或子切片管理功能NSSMF所上报。通过上述方案，能够克服移动网络管理技术中，在采用网络切片技术的背景下，当被多个网络切片/子切片共享的网络功能出现故障时，没有合适的告警信息表达方式来上报告警信息的技术问题，从而大大地改善了网络性能。
实施例一
参见图3，本实施例中，在告警信息里，增加一个可选字段(比如命名为affectedSliceList)，用于当被共享的NF发生故障时记录受影响的网络切片和子切片的ID。
当NF发生故障时，NF在生成一般的告警信息外，NF对故障进行分析，判断是否有网络切片或子切片受到所述故障的影响，若有，则将受影响的网络切片或子切片的ID填入相应的告警信息的affectedSliceList字段；NF将告警上报给NSSMF。
NSSMF收到告警后，可能会根据告警信息进行相应的管理操作，但NSSMF会对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的ID填入相应的告警信息的affectedSliceList字段；NSSMF将告警上报给NSMF。
NSMF根据收到的告警信息进行相应的管理操作，如故障的修复等，但并不以此为限。
实施例二

NF管理功能NFMF在生成相应的告警信息的时候，对故障进行分析，判断是否有网络切片和子切片受到所述故障的影响，若有，则将受影响的网络切片和子切片的ID填入相应的告警信息的affectedSliceList字段；NF管理功能将告警上报给NSSMF。
NSSMF收到告警后，可能会根据告警信息进行相应的管理操作，但NSSMF会对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的ID填入相应的告警信息的affectedSliceList字段；NSSMF将告警上报给NSMF。

所述NF管理功能在生成相应的告警信息的时候，对故障进行分析，判断是否有网络切片和子切片受到所述故障的影响，若有，则将受影响的网络切片和子切片的ID填入相应的告警信息的additionalInformation字段；NF管理功能将告警上报给NSSMF。
NSSMF收到告警后，可能会根据告警信息进行相应的管理操作，但NSSMF会对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的additionalInformation字段，则将受影响的网络切片的ID填入相应的告警信息的additionalInformation字段；NSSMF将告警上报给NSMF。

当NF发生故障时，NF包含的NF管理功能NFMF对故障进行分析，判断是否有网络切片和子切片受到所述故障的影响，若有，则将受影响的网络切片和/或子切片的ID填入相应的告警信息的affectedSliceList字段；NF管理功能将告警上报给NSSMF。
NSSMF收到告警后，可能会根据告警信息进行相应的管理操作；但NSSMF会对告警做进一步的分析，判断是否有网络切片受到所述故障的影响，若有，且该受影响的网络切片的标识还没有被加入告警信息的affectedSliceList字段，则将受影响的网络切片的ID填入相应的告警信息的affectedSliceList字段；NSSMF将告警上报给NSMF。
