Description

一种网元的性能数据处理方法及装置和NMS 技术领域
本发明实施例涉及无线通讯系统的管理技术，尤指一种网元的性能数据处理方法及装置和NMS。
背景技术
在无线通讯系统的管理领域，网络管理系统(NMS，Network Management System)与网元管理系统(EMS，Element Management System)之间的接口称为北向接口(Itf-N)。其中，EMS主要用于完成国际电信联盟(ITU，International Telecommunication Union)电信管理网络(TMN，Telecommunications Management Network)中的网元管理层(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。NMS主要用于完成ITU TMN中的网络管理层(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(也称为子网)内存在多个设备供应商的情况，可以通过各自的EMS管理达到管理整个子网的目的。
而在运营商的整个管理系统中，一般还包含运营支撑系统(OSS，Operations support system,)、业务支撑系统(BSS，Business support system)。从总体上看，一般认为NMS包含在OSS中，是OSS的一部分。
目前，为了提高通讯网络的灵活性，降低管理成本，由运营商发起提出了网络功能虚拟化(NFV，Network Functions Virtualization)概念。图1为相关技术中网络功能虚拟化参考架构示意图，在使用NFV技术的情况下，原来的物理网元设备由虚拟化网络功能(VNF，Virtualized Network Function)代替，使得网络功能与具体硬件解耦，如图1所示，VNF与底层的网络功能虚拟化基础架构(NFVI，Network Functions Virtualization Infrastructure)隔离。其中，对于VNF的管理，通过EMS对VNF实例进行传统的维护管理功能，而VNF的生命周期管理功能则通过VNF管理器(VNFM)完成。底层的虚拟基础架构由虚拟基础架构管理器(VIM)进行管理。而具体的网络业务，则一般通过一个或多个VNF实例来完成。对网络业务的管理，则通过NFV 编排器(NFVO)来进行。
实现网络功能虚拟化后，从应用层面来看，要建立一个网络业务实例，要先生成网络业务需要的VNF的实例，再由一个或多个VNF实例组成一个网络业务实例，最后通过网络业务实例来提供网络业务。而网络功能虚拟化后的一个好处是，随着网络使用情况的变化，可以动态调整组成网络业务的VNF实例所使用的资源，即对VNF实例进行伸缩，以提高资源的利用率，并达到节能的目的。
在网络虚拟化的基础上，业界已进一步开始了第五代移动通讯技术(5G)的研究，而网络切片是5G的一个重要组成部分。所谓网络切片，主要是指由一组网络功能(包含支持这些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，其中，网络特性可以是指超低延时、超高可靠性等。网络切片是根据网络切片蓝图进行实例化而获得的，因此也称为网络切片实例。网络切片蓝图是指一个完整的定义，用于描述网络切片实例的结构、配置、工作流，根据网络切片蓝图的定义完成网络切片的实例化及其生命周期的控制管理。也就是说，不同的网络切片是为了满足不同类型的应用的需求，所以一般具有不同的性能要求。

本发明的较佳实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
基于网络切片的提出，本申请发明人认为，当对5G网络系统进行集中管理时，就需要区分不同的网络切片，根据每类网络切片的具体的性能需求，采用不同的管理策略进行管理，才能满足具体的网络业务的需求。所以，系统在采集相应的性能监测数据时，也需要保证采集的数据能按照具体的网络切片进行区分。目前的网络管理系统中，还没有考虑网络切片的因素，无法实现性能数据按网络切片区分进行采集、分析并作出相应的管理操作，从而无法保证对应用网络切片的5G网络的正确维护、管理。
图2为本发明实施例网元的性能数据处理方法的流程图，如图2所示，包括：
步骤200：NMS收集网元的性能数据，在性能数据中包含用于区分网元所属的网络切片的唯一标识。
本步骤中，可以从以下网元收集性能数据但不限于如下几种：EMS，或NFVO，或EMS和NFVO。如何实现收集可以采用现有技术实现，是本领域技术人员的惯用技术手段，并不用于限定本发明实施例的保护范围，这里不再赘述。
该方法之前还包括：在性能数据中携带网元所属的网络切片的唯一标识。具体可以但不限于通过以下方式来实现：
新增用于直接或间接地包含作为性能数据采集对象的网元的网络切片管理对象，从而在性能数据采集对象的区别名(DN，Distinguished Name)中就包含网络切片的唯一标识如网络切片ID；其中，间接包含是指网络切片管理对象包含子网，从而间接包含了被子网包含的作为性能数据采集对象的网元；其中，DN可以用来唯一的区分一个管理对象，一个管理对象的DN中包含了在管理对象树上包含它的上级对象的唯一标识，具体DN的定义可以参考相关协议，这里不再赘述。
或者，在性能数据上报数据中新增一个属性，用于表示网元所属的网络切片的唯一标识如网络切片ID。
其中，网元可以是物理网元，也可以是虚拟化网元，还可以既包括有物理网元也包括有虚拟化网元。如果是虚拟化网元，该网元一般包含VNF实例。
本步骤中的NMS收集网元的性能数据的方式具体包括但不限于：
方式一：NMS从EMS和NFVO收集网元的性能数据；或者，
方式二：NMS从NFVO收集网元的性能数据；或者，
方式三：NMS从EMS收集EMS自身采集的VNF实例的性能数据，此时，网元所属的网络切片的唯一标识为VNF实例所属的网络切片的唯一标识；或者，
方式四：NMS接收EMS上报的EMS自身采集的VNF实例的性能数据，此时，网元所属的网络切片的唯一标识为VNF实例所属的网络切片的唯一标识；或者，
方式五：NMS从EMS收集VNF实例的性能数据采集性能数据，此时，网元所属的网络切片的唯一标识为VNF实例所属的网络切片的唯一标识。
本步骤中，通过采集网元的性能监测数据，获知了相应的网元所属的网络切片的唯一标识，保证了后续能按照获得的网元所属的网络切片的唯一标识对收集到的网元的性能数据进行区分，进而可以采用不同的管理策略进行管理，以满足具体的网络业务的需求。
步骤201：NMS根据网元所属的网络切片的唯一标识对收集到的网元的性能数据进行区分，并以网络切片为单位，根据相应网络切片的性能要求进行性能分析。
本步骤强调的是，网元的性能数据按照网络切片区分，进行与网络切片的性能要求对应的分析，即实现了对网元的性能数据的分析基于不同类的网络切片进行。
进一步地，本发明实施例还包括：
步骤202：NMS根据性能分析的结果，发起相应的网络切片的自动维护处理。也就是说，根据以网络切片为单位的性能分析的结果发起相应的网络切片的自动维护处理。
本步骤中的网络切片的自动维护处理包括但不限于伸缩。
对于NMS主动收集性能数据的情况即：方式一、方式二、方式三和方式五，本步骤具体包括：
NMS根据以网络切片为单位的性能分析的结果发起相应的网络切片的自动维护处理，包括但不限于伸缩。
对于NMS被动收集性能数据的情况即方式四，本步骤具体包括：
NMS将根据以网络切片为单位的性能分析的结果发起的针对该网络切片的自动维护指令如伸缩指令发送给EMS，由EMS将伸缩指令转发给VNFM以完成对VNF实例的伸缩。
由于本发明实施例中对网元的性能数据的分析是基于不同类的网络切片进行的，因此，相应的网络切片的自动维护处理也是针对不同类的网络切片进行的，这样保证了采用不同的管理策略进行管理，满足了具体的网络业务的需求，进而保证了对应用网络切片的5G网络的正确维护、管理。
通过本发明实施例提供的技术方案，由于通过采集网元的性能监测数据时，获知了相应的网元所属的网络切片的唯一标识，使得网元的性能数据按照网络切片区分，以进行与网络切片的性能要求对应的分析，实现了对网元的性能数据的分析基于不同类的网络切片进行。这样，相应的网络切片的自动维护处理也是针对不同类的网络切片进行的，保证了采用不同的管理策略进行管理，满足了具体的网络业务的需求，进而保证了对应用网络切片的5G网络的正确维护、管理。

针对收集模块的具体实现，当接收模块具体用于：接收EMS上报的EMS自身采集的VNF实例的性能数据，在性能数据中包含用于区分VNF实例所属的网络切片的唯一标识时，维护模块还用于：将根据以网络切片为单位的性能分析的结果发起的针对该网络切片的自动维护指令如伸缩指令发送给EMS。
其中，网元可以是物理网元，也可以是虚拟化网元，还可以既包括有物理网元也包括有虚拟化网元。如果是虚拟化网元，该网元一般包含VNF实例。
