Description

网络管理方法和装置
本公开要求在2018年03月29日提交中国专利局、申请号为201810270938.3的中国专利申请的优先权,该申请的全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域,例如涉及一种网络管理方法和装置。
背景技术
在无线通讯系统的管理领域,网络管理系统(Network Management System,NMS)与网元管理系统(Element Management System,EMS)之间的接口称为北向接口(Itf-N)。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(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。NMS主要完成ITU 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)技术标准(Tchnology Standard,TS)28.622)内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系统中,一般还包含运营支撑系统(Operations support system,OSS)、业务支撑系统(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。
业界已进一步开始了第5代移动通信技术(5th Generation mobile communication tchnology,5G)的研究,而网络切片(Network Slice)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、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,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、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其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(Network Slice Subnet),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其生命周期的控制管理。
对于5G网络,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(Communication Service Management Function,CSMF),从而5G网络切片的管理分为三层:CSMF-NSMF-NSSMF,如图1所示。
在性能管理方面,业界提出来性能数据流(Performance data streaming)的概念,也就是实时性能数据,即性能数据以很短的时间间隔进行上报,实时反映系统性能。
相关技术中,在性能数据通过数据流进行实时上报的情况下,未能充分利用这些性能数据,网络性能有待改善。

对于5G网络性能管理来说,根据性能数据计算得出的KPI是反映系统性能的一种重要指标。当性能数据通过数据流进行实时上报时,如果能同时做到KPI的实时产生,则5G网络系统的性能状态也可以更加及时地得到体现。为了改善移动网络管理技术中没有产生实时KPI的方法的问题,本公开提出一种利用性能数据流生成实时KPI的方法,实现了网络性能的管理的优化。
图2为一实施例提出的一种网络管理方法的流程示意图,参见图2,本实施例提供的方法包括如下步骤。
步骤100、接收KPI生成指令,所述KPI生成指令中携带有指令参数。
步骤200、根据所述KPI生成指令,执行配置过程,并创建KPI生成任务。
步骤300、在完成相应的配置之后,根据配置参数执行对应的KPI生成任务。
通过本实施例的方案,能做到KPI的实时产生,并且用户可以用通用的KPI任务建立请求来建立一个KPI生成任务,通过将指令参数转换为KPI生成任务所需要的配置参数,保证KPI生成任务的顺利执行,使得KPI生成任务的执行更加灵活,从而在保证灵活易用的情况下,使得5G网络系统的性能状态可以更加及时地得到体现,从而优化了网络性能的管理。
在一实施例中,步骤100和步骤200由KPI管理服务模块执行,步骤300由KPI生成模块执行。

步骤210、将KPI生成指令中包含的指令参数,转换为KPI计算流程相关的配置参数。
步骤220、根据转换的配置参数,建立KPI计算流程。
本实施例中,通过KPI管理服务模块对KPI生成服务模块的配置过程,使得上层管理系统或消费者之类的用户可以用通用的KPI任务建立命令来建立一个KPI生成任务,输入的是统一的命令和参数,然后通过KPI管理服务模块将通用的指令参数转换为KPI生成服务模块可以接受的配置参数,这样KPI生成服务模块的使用可以更加灵活,而可以不管用户用的是什么KPI生成服务模块。
在一实施例中,步骤300中,所述根据配置参数执行对应的KPI生成任务包括如下步骤。
步骤310、根据配置参数读取KPI生成任务所需要的性能数据。
步骤320、根据读取的性能数据,计算KPI。
在一实施例中,所述根据配置参数读取KPI生成任务所需要的性能数据包括:根据确定的KPI计算公式确定需要获取的数据类型;确定时间区间[t1,t2];其中,t1为当前时间减去KPI计算区间所得到的时间点,t2是当前时间,KPI计算区间是从指令参数中获取的时间区间大小;根据确定的数据类型和时间区间读取相应的性能数据。
在一实施例中,在所述根据读取的性能数据,计算KPI之后,所述方法还包括:检测KPI是否超过预设的KPI阈值,在KPI超过预设的KPI阈值的情况下,上报KPI阈值告警信息。
本实施例中,KPI管理服务模块和KPI生成服务模块可以是单独的功能模块,也可以是其他功能模块的一部分,或是管理系统的一部分。
对于5G网络系统来说,KPI的生成可以在网络切片层、网络子切片层、网络功能层或网络层进行,即计算得到的KPI可以是网络切片的KPI、网络子切片的KPI、网络功能的KPI或网络的KPI。
本实施例中,KPI计算对象标识是指要计算KPI的管理对象实例的标识,可以是网络功能实例、网络切片实例、网络子切片实例或整个网络的标识;对于网络功能实例,则是网络功能实例的标识,如网络功能(Network Function,NF)Id;对于网络切片实例,这是网络切片实例的标识,如网络切片实例(Network  Slice Instance,NSI)ID;对于网络子切片实例,则是网络子切片实例标识,如(Network Slice Subnet Instance,NSSI)ID;对于网络,则是网络标识,如网络(Network)ID。
本实施例中,KPI类型是指预定义的KPI,每一个KPI类型对应一个KPI计算公式;对于没有预定义的KPI,则在KPI任务生成指令中直接给出KPI计算公式。
本实施例中,KPI上报间隔是指每隔多久计算并上报一次KPI。
本实施例中,KPI计算区间是指在计算KPI的情况下,取用多少时间范围的数据进行计算,这个时间范围是从要计算KPI这个时刻往前倒推的时间范围。一般KPI计算区间会大于或等于KPI上报间隔。
本实施例中,性能数据流存储空间里的性能数据是指性能数据流采集模块采集的性能数据流,存放在性能数据流存储空间里。有关性能数据流采集模块,不在本公开的范围。性能数据流采集模块和KPI生成服务模块的关系见图3。其中,基本操作流程如下。
1.认证消费者(包括经过认证的管理系统或功能模块)给性能数据流采集模块下发建立性能数据流采集任务的请求。

4.性能数据流采集模块执行性能数据流采集任务,定期采集并上报性能数据流。
5.KPI生成服务模块执行KPI生成任务,定期计算并上报KPI。
