Description

网络切片实例的性能管理方法及装置
本申请要求于2017年1月5日提交中国专利局、申请号为201710008506.0、申请名称为“网络切片实例的性能管理方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域，尤其涉及一种无线通信***中的网络切片实例的性能管理方法和装置。
背景技术
随着无线通信技术的飞速发展，第五代(5th Generation；简称：5G)无线通信技术已是目前业界的热点。5G将支持多样化的应用需求，其中包括支持更高速率体验和更大带宽的接入能力、更低时延和高可靠的信息交互、以及更大规模且低成本的机器类通信设备的接入和管理等。此外，5G将支持面向车联网、应急通信、工业互联网等各种垂直行业应用场景。面对5G这些性能要求和应用场景，5G网络需要更加贴近用户特定需求，其定制化能力需要进一步提升。
为此，5G引入了网络切片这一重要概念。一个网络切片是实现通信业务的多个网络功能和相应资源的组合。5G网络由满足不同连接能力的各种网络切片组成，一个网络切片是满足一类或一个用例的通信服务需求的逻辑网络。图1示出了引入网络切片概念后的5G网络场景，其中包含了关键机器类通信(Critical Machine Type Communication；简称Critical MTC)、大规模机器类通信(Massive Machine Type Communication；简称Massive MTC)和移动宽带(Mobile Broad Band；简称MBB)三种用例的通信。如图1所示，3GPP运营商网络可包含关键机器类通信网络切片、大规模机器类通信网络切片和移动宽带网络切片，其中每一个网络切片服务不同用例的通信服务。
统一的网络平台，利用动态的、安全的网络切片支持不同功能和服务质量要求的通信服务，是5G网络的基本能力之一。一个网络切片所构成的逻辑网络是通过该网络切片实例来实现，即通过实例化网络切片的各个网络功能和对应的资源来构成一个网络切片。为了保证网络切片能正常运行，5G网络需要对网络切片实例的性能进行管理。如何管理网络切片实例的性能，目前尚未有适当的解决方案。

下面将结合本发明实施例中的附图，对本发明实施例进行描述。

下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
作为5G的一个关键特性，5G网络可划分成多个网络切片。一个网络切片(Network Slice；简称NS)对应一个逻辑网络，该逻辑网络用于满足一个用例的通信服务需求。一个网络切片由一个或多个网络功能(Network Function；简称NF)组成，并通过网络切片实例(Network Slice Instance；简称NSI)来实现，即通过实例化网络切片的各个网络功能和对应的资源及配置来构成一个网络切片。一个网络切片可以包含一个或多个网络切片实例，不同的网络切片实例可具有不同的网络功能和/或资源的配置。对网络切片实例的性能管理，是保障5G网络正常运行的关键技术之一。
图2示出了一种可能的网络管理架构示意图。如图2所示，网络功能架构分为三个层次。位于最底层的是网元(Network Element；简称NE)，可以包括核心网设备、接入网设备以及用户设备。核心网设备可以包含移动性管理实体(Mobility Management Entity；简称MME)、服务网关(Serving Gateway；简称S-GW)、报文数据网络网关(Packet Data Network Gateway；简称PDN-GW)等；接入网设备可以包括各种形态的基站，如宏基站，微基站，中继站，接入点等；用户设备可以包括智能手机、移动通信终端、物联网终端、无线抄表器等。位于中间层的是网元管理***(Element Management System；简称EMS)，可以包括域管理器(Domain Manager；简称DM)和网元管理器(Element Manager；简称EM)。EM提供管理一个网元或者具有相同类型的一类网元的网元管理功能。例如，一个EM可以管理一个或多个基站。EM可以独立于被管理的网元存在，也可以内置在被管理的网元中。DM可提供网元管理功能和/或域管理功能。DM管理的一个域可以是一个设备提供商提供的具有相同类型的多个网元的集合，如一个设备提供商提供的接入网设备等。位于最上层的是网络管理***(Network Management System；简称NMS)，可以包括网络管理器(Network Manager；简称NM)，用于管理不同地域、不同设备提供商提供的网络设备。其中，NMS的NM和EMS的DM/EM通过北向接口(Interface N；简称Itf-N)进行通信。
目前3GPP移动通信***的网络性能管理由技术规范TS32.4xx系列标准定义，主要标准化的接口是NMS和EMS之间的Itf-N接口。NMS通过Itf-N接口与EMS交互进行性能管理。性能管理通常包含性能测量和性能监控。例如，对于性能测量，其工作流程主要包括：NMS通过Itf-N接口向EMS创建测量任务(createMeasurementJob)，上述创建测量任务的输入参数可包括要测量的NE类型(iOCName)、要测量的NE实例列表(iOCInstanceList)、测量类型列表(measurementCategoryList)、测量时间粒度(granularityPeriod)、发送测量报告的时间间隔(reportingPeriod)、测量任务的开始时间(startTime)、测量任务的结束时间(stopTime)、测量任务计划(schedule)、以及测量任务的优先级(priority)等；EMS接收到创建测量任务后，根据相应的测量任务向NE创建具体的测量任务，并向NMS返回创建测量任务输出参数，其中上述输出参数可包括测量任务标识(jobId)、网络设备不支持的测量类型(unsupportedList)、以及该测量任务的状态(status)等。类似地，对于性能监控，其工作流程主要包括：NMS通过Itf-N接口向EMS创建阈值监控任务(createThresholdMonitor)，作用在于为某些测量类型设置阈值，当测量值超过或者达到阈值时，向NMS告警。上述创建监控任务的输入参数可包括要监控的网元类型(iOCName)、要监控的网元实例列表(iOCInstanceList)、测量类型的阈值信息列表(thresholdInfoList)、以及读取阈值的时间间隔(monitorGranularityPeriod)等；EMS接收到创建阈值监控任务后，根据相应的阈值监控测量任务向NE创建具体的阈值监控任务，并向 NMS返回创建阈值监控任务输出参数，其中上述输出参数可包括阈值监控任务标识(monitorId)、网络设备不支持阈值监控的测量类型(unsupportedList)、以及该阈值监控任务的状态(status)等。
在5G网络中，网络切片技术的引入，使得网络管理架构中的网元不再限于传统的网元，还包括网络功能。其中网络功能是用于实现通信的一种处理功能，可以是物理网络功能(Physical Network Function；简称PNF)也可以是虚拟网络功能(Virtual ized Network Function；简称VNF)。例如，PNF可以包含基站；VNF可以包含核心接入与移动性管理功能(Core Access and Mobility Management Function；简称AMF)、会话管理功能(Session Management Function；简称SMF)、用户面功能(User plane Function；简称UPF)、网络切片选择功能(Network slice selection function；简称NSSF)等。在基站采用集中控制单元和数字处理单元的架构时，VNF还可包括基站的集中控制单元的非实时处理功能、无线资源管理功能等。PNF可以是使用专用的硬件实现；VNF可以是在通用的硬件平台如网络功能虚拟化基础设施(Network Function Virtualization Infrastructure；简称NFVI)上以虚拟机的形式实现。此外，在NMS中引入了网络切片管理与编排器(Network Slice Manager and Orchestrator；简称NSM&O)模块。NSM&O包含网络切片管理功能，可以内置于现有的NM上，也可以作为独立的NM设备存在。NSM&O的主要作用是实现对网络切片的管理和编排，包括网络切片生命周期管理、网络切片的性能管理、以及网络切片的故障管理等。此外，网络切片技术的引入，使得EMS具有对网络切片的支持能力，例如能够感知网络切片实例的标识。网络功能的引入使得EMS需要具有管理网络功能的能力。相应地，在网络管理架构的网元管理***层，有相应的网络功能的管理实体(如网络功能管理器)，该功能实体可以是独立于DM/EM而存在，也可以通过增强DM/EM功能的方式在DM/EM上实现网络功能管理的作用。
图3示出一种可能的网络切片实例与网络功能的对应关系示意图。如图3所示，网络切片实例1由网络功能1至网络功能4和各个功能使用的资源及配置所组成；网络切片实例2由网络功能5至网络功能8和各个功能使用的资源及配置所组成；网络切片实例3由网络功能7至网络功能12和各个功能使用的资源及配置所组成。其中，网络功能1至网络功能6以及网络功能9至网络功能12中的任一个网络功能是由一个网络切片实例专用，称为专属网络功能；网络功能7和网络功能8是由多个网络功能实例共享使用，称为共享网络功能。
一个端到端的网络切片实例可能会跨越多个域，如覆盖不同的设备形态和多个设备商的产品。因此，实际网络中的一个网络切片实例可能被划分为不同的域进行性能管理。此外，关于域的划分并不局限于特定范围和场景，例如专属网络功能和共享网络功能可以分别属于不同的域。在一个网络切片实例跨越多个域的情况下，一个网络切片实例的任一个域内的网络功能和相应的资源的总和称为该网络切片实例的一个网络切片实例子网。不同的网络切片实例子网可共享一个或多个网络功能。结合图3所示的网络切片实例和网络切片功能，图4示出一种可能的网络切片实例子网的示意图。如图4所示，网络切片实例1不存在子网，其所使用的网络切片功能1至网络切片功能4没有被划分为到不同的子网中；一种可能的情况是网络切片实例1所包含的网络功能和资源都是由一个设备商所提供。网络切片实例2由网络切片实例子网1和网络切片实例子网2组成，其中网络切片实例子网1包含网络功能5和网络功能6，网络切片实例子网2包含网络功能7和网络功能8；网络切片实例3由网络切片实例子网2至网络切片实例子网4组成，其中网络切片实例子网2为与网络切片实例2共享的网络切片实例子网，网络切片实例子网3包含网络功能 9和网络功能10，网络切片实例子网4包含网络功能11和网络功能12。
