本申请要求在2019年08月08日提交中国专利局、申请号为201910730071.X、申请名称为“一种管理数据的获取方法及装置”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
本申请涉及移动通信技术领域,尤其涉及一种管理数据的获取方法及装置。
背景技术
随着各种通信业务的不断涌现,不同的通信业务对网络性能的需求存在显著的区别,5G通信系统引入了网络切片(network slice)来满足不同通信业务对网络性能的差异化需求。网络切片是在物理或者虚拟的网络基础设施上,根据不同的服务需求定制化的逻辑网络。网络切片可以是一个包括了终端设备、接入网、传输网、核心网和应用服务器的完整的端到端网络,能够提供完整的通信服务。
通常情况下,不同网络切片的网络性能要求并不相同,运营商将通信网络划分成一系列的网络切片后,各个网络切片彼此之间是逻辑隔离,同时又具备不同的网络特征,不同客户可以在运营商订购多个网络切片,从而使得运营商的一张物理网络就能满足不同应用对网络的差异化需求。
由于网络切片实例是相对隔离的逻辑网络,运营商往往根据业务的需要开放一部分管理数据给租户(如其他运营商等),比如让租户获得部分网络性能结果或者部分告警信息,便于租户了解网络切片运行状况,便于租户开展自身的业务。
目前还没有一种很好的控制租户在合理范围内获取管理数据的方法。

统一数据管理网元:负责管理终端的签约信息。在5G通信系统中,统一数据管理网元可以是统一数据管理(unified data management,UDM)。
统一数据存储网元:负责存储结构化的数据信息,其中包括签约信息,策略信息,以及有标准格式定义的网络数据或业务数据。在5G通信系统中,统一数据存储网元可以是统一数据存储(unified data repository,UDR)。
网络仓库功能网元:在5G通信系统中,网络仓库功能网元可以是网络仓库功能(network repository function,NRF)。
为了支持网络切片,第三代合作伙伴计划(3rd generation partnership project,3GPP)定义了如图2所示的网络切片的标识和相关定义。
运营商根据客户订单,按照网络切片模板在通信网络的物理基础设施上为客户创建出来的一个具备特定网络特性和支持特定业务能力的相对隔离的逻辑网络,称为一个网络切片实例(Network Slice instance,NSI),网络切片实例可以使用NSI ID来标识。
终端设备和网络使用网络切片选择辅助信息(network slicing selection assistance information,NSSAI)来为终端设备的各种通信业务选择合适的网络切片实例。NSSAI由一组单个网络切片选择辅助信息(single network slice selection assistance information,S-NSSAI)组成。每个S-NSSAI由SST(切片/业务类型)和SD(切片区分符)两部分组成。SST分为标准的和自定义的两类,标准的是所有运营商的5G网络都支持的,能够确保漫游场景中终端用户的业务体验一致性;自定义的是只在本运营商的5G网络内支持,如果漫游,需要本运营商和其它运营商签订的漫游协议中支持在漫游网络将其映射为标准SST或其它运营商自定义的SST。目前定义的标准SST有增强的移动宽带(Enhanced Mobile Broadband,eMBB)、超低时延超高可靠性通信(Ultra-Reliable and Low-Latency Communication,URLLC)和海量物联网(Massive Internet of Thing,MIoT)。SD用来区分相同SST的多个网络切片,具体如何使用标准上不做限定。
网络切片经常以NSaaS(Network Slice as a Service)方式提供给客户,运营商部署一个网络切片实例向第三方(可以是企业、互联网服务提供商,或者另外一个运营商等)提供服务。网络切片实例(network slice instance,NSI)是运营商为特定客户提供网络切片业务所创建的一个能够真实运行的逻辑网络。创建网络切片实例是分配网络资源,并通过编排和配置形成一个相对隔离的逻辑网络的过程。也就是S-NSSAI作为终端设备允许使用的网络切片业务的标识,而NSI是网络切片的资源。终端设备附着到5G网络后,AMF和NSSF配合,根据S-NSSAI为终端设备选择提供服务的网络切片实例。如图2所示,S-NSSAI#1的业务会选择到网络切片实例#1,而S-NSSAI#2和S-NSSAI#3的业务都会选 择到网络切片实例#2。
因为网络切片实例是相对隔离的逻辑网络,运营商往往根据业务的需要开放一部分管理数据给客户。例如网络切片实例的客户是企业或互联网服务提供商时,常常会允许客户获得网络切片实例的某些关键性能指标(Key Performance Indicator,KPI)数据,比如网络切片的端到端时延等等。当网络切片实例的客户是另外一个运营商时,除了会允许客户获得网络切片实例的某些关键指标外,还常常会允许客户获得网络切片实例的告警信息和事件记录,以便于及时处理故障。
一个具体的网络管理行为包括管理的动作和管理对象,以及和管理对象相关的管理数据。在3GPP定义的标准规范中,管理服务(Management Service,MnS)是由操作、管理对象和管理数据三个组成部分组合构成的:
(1)操作是指创建、修改、删除、查询、订阅、通知等管理动作。
(2)管理对象是可被管理的网络资源,包括网络功能(network function,NF),网络切片实例等等。管理对象又称为管理对象实例(Managed Object Instance,MOI)。MOI是管理对象类(Managed Object Class,MOC)的一个具体的实例。MOC是可被管理的网络资源的抽象的类定义,而MOI是具体的可被管理的网络资源。
(3)管理数据是管理对象的具体的关键性能指标或故障告警信息。
MOC的描述形式为对象类信息(Information Object Class,IOC),一系列IOC的集合构成了网络资源模型(Network Resource Modeling,NRM)。管理信息数据库(Management Information Base,MIB)是NRM的一个实例,存储了一系列MOI,以及MOI的属性和相互关联关系。
现有技术通过将管理对象实例关联租户标识(如其它运营商或垂直行业的身份标识)进行管理开放的授权和控制。如果租户希望获得管理数据,则现有技术检查希望获得的管理数据是哪个管理对象实例(比如图2中的网络切片实例#2)的性能测量数据或告警信息,然后判断租户是否对这个管理对象实例具有管理权限。如果有,就允许租户获得管理对象实例的管理数据。
在切片即服务的商业场景下,租户订购的是网络切片通信业务,标识为S-NSSAI,而网络切片实例作为管理对象实例,它和S-NSSAI之间并不是一对一关系。例如图2中的网络切片实例#2为两个不同的租户分别提供以S-NSSAI#2和S-NSSAI#3标识的网络切片通信业务。现有技术只对管理对象实例,即网络切片实例#2,进行权限控制,容易导致租户获得超出应有权限的管理数据。具体的,以图2中的情况为例,某个租户订购了以S-NSSAI#2标识的网络切片通信业务,但是按照现有技术,该租户具备获得管理对象实例网络切片实例#2的管理数据的权限,那么他既能获得以S-NSSAI#2标识的网络切片通信业务相关的性能统计数据和告警信息,也能获得以S-NSSAI#3标识的网络切片通信业务相关的管理数据,而后者超出了租户应有的管理权限,不能满足各个租户之间管理数据隔离的要求。
因此,本申请要解决的问题是:第三方(其它运营商或垂直行业用户)如何在合理的权限范围内获取运营商开放给租户的性能测量数据和告警事件信息等管理数据。具体的,当一些管理对象实例同时处理多个网络切片的业务时,租户应该只允许获得自身订购切片业务相关的管理数据。
本申请发明点概述如下:其它运营商或垂直行业用户作为运营商的网络切片租户(即 管理数据请求者)请求获得管理数据,运营商的网络管理系统(即管理服务提供者)根据管理数据请求者的租户身份获得其对应的S-NSSAI,根据获得的S-NSSAI判断管理数据请求者是否允许获取管理对象的管理数据。如果允许,根据管理数据请求者对应的S-NSSAI为性能测量任务补充测量子项,然后将管理数据请求者对应S-NSSAI的网络切片子项性能测量数据作为性能测量结果报告给管理数据请求者;或者,根据租户对应的S-NSSAI为告警订阅任务补充过滤参数,将租户对应的S-NSSAI的添加到过滤条件中,然后将告警事件信息按照上述过滤条件进行过滤,过滤后的结果报告给管理数据请求者。
上述根据管理数据请求者的租户身份获得S-NSSAI具体可以为:从商用系统的租户订购切片的信息,根据管理数据请求者的租户身份获取管理数据请求者对应的S-NSSAI;或者,租户订购的S-NSSAI作为管理数据请求者的租户身份标识,从订阅管理数据的请求中的租户身份获得S-NSSAI。
上述根据获得S-NSSAI判断管理数据请求者是否具备获取管理对象的管理数据的权限具体可以为:根据管理对象属性中的S-NSSAI列表中是否包含管理数据请求者对应的S-NSSAI来判断管理数据请求者是否被授权获得所述S-NSSAI标识的网络切片子项性能测量数据;或者,根据管理对象属性中的S-NSSAI列表中是否包含管理数据请求者对应的S-NSSAI来判断管理数据请求者是否被授权获得使用所述S-NSSAI标识过滤后的告警事件信息。
通过本申请方法,能够自动验证管理数据请求者是否被授权获得管理对象示例的开放性能测量数据和告警事件信息,并且能够确定被授权的上述管理数据的范围(即哪些网络切片相关的性能测量数据和告警事件信息)。能够自动将管理数据请求者没有订购网络切片的性能测量数据或告警信息从管理数据中过滤掉,第三方在合理的权限范围内获取性能测量数据和告警事件信息。
下面进行具体说明。
基于图1所示的架构,申请提供一种管理数据的获取方法流程示意图,如图3所示,该方法包括以下步骤:
步骤301,第二网元向第一网元发送请求消息。相应地,第一网元可以接收到该请求消息。该请求消息指示租户标识和至少一个管理对象实例,该租户标识对应至少一个第一网络切片业务标识。
这里的第二网元也可以称为管理数据请求者,比如具体可以是租户对应的终端设备,该租户可以是其它运营商或垂直行业用户。第一网元也可以称为管理服务提供者,比如具体可以是运营商。
该请求消息用于请求获取管理对象实例中的管理数据。
这里的管理对象实例可以是网络功能(如AMF、SMF、UPF等)、网络切片实例、子网切片实例中的一项或多项。
作为一种实现方法,该请求消息中携带上述租户标识。在步骤301之后步骤302之前,第二网元还确定该租户标识对应的上述至少一个第一网络切片业务标识。下面介绍几种确定该租户标识对应的上述至少一个第一网络切片业务标识的方法:
方法1,租户标识为上述至少一个第一网络切片业务标识。
基于该方法,租户标识本身即为上述至少一个第一网络切片业务标识,从而第二网元获取到租户标识后,即可确定该租户标识对应的上述至少一个第一网络切片业务标识。
方法2,第一网元根据租户标识,从第三网元获取与租户标识对应的至少一个第一网络切片业务标识。
根据第三网元的不同,该方法2可以进一步划分为以下方法2.1至方法2.3。
方法2.1第三网元为第一网元。
即第一网元本地存储有租户标识与网络切片业务标识的对应关系,从而第一网元可以从本地获取租户标识对应的上述至少一个第一网络切片业务标识。
方法2.2第三网元为第二网元。
即第一网元从请求消息获取到租户标识之后,再根据租户标识向第二网元请求获取该租户标识对应的上述至少一个第一网络切片业务标识。
方法2.3第三网元为数据库。
即数据库(如MIB、NRM信息库或业务发放管理数据库)中存储有租户标识与网络切片业务标识的对应关系,从而第一网元可以从数据库获取租户标识对应的上述至少一个第一网络切片业务标识。
步骤302,第一网元根据第一网络切片业务标识,确定至少一个管理对象实例中的第一管理对象实例,其中,第二网元具备获取第一管理对象实例的管理数据的权限。
即该步骤302确定出的第一管理对象实例,是上述至少一个管理对象实例中的第二网元具备获取管理数据的权限的管理对象实例。比如,可以根据以下方法确定第一管理对象实例:针对上述至少一个管理对象实例中的任一管理对象实例,第一网元确定任一管理对象实例的第一属性中包含第一网络切片业务标识,则确定该任一管理对象实例为第一管理对象实例。
需要说明的是,这里的第一属性也可以称为网络切片业务标识属性或S-NSSAI属性。第一网元可以从数据库中获取到每个管理对象实例的第一属性。
下面结合一个示例对该方法进行说明。比如:
上述租户标识对应的至少一个第一网络切片业务标识为:
S-NSSAI#1和S-NSSAI#2;
上述请求消息指示的至少一个管理对象实例为:
MOI#1,且MOI#1的第一属性包括S-NSSAI#1、S-NSSAI#2和S-NSSAI#3;
MOI#2,且MOI#2的第一属性包括S-NSSAI#1、S-NSSAI#3和S-NSSAI#4;
MOI#3,且MOI#3的第一属性包括S-NSSAI#3、S-NSSAI#4和S-NSSAI#5。
针对S-NSSAI#1,由于MOI#1和MOI#2的第一属性包括S-NSSAI#1,MOI#3的第一属性不包括S-NSSAI#1,因此S-NSSAI#1对应的第一管理对象实例为:MOI#1、MOI#2。
针对S-NSSAI#2,由于MOI#1的第一属性包括S-NSSAI#2,MOI#2和MOI#3的第一属性不包括S-NSSAI#2,因此S-NSSAI#2对应的第一管理对象实例为:MOI#1。
上述MOI#1和MOI#2即为第二网元具备获取管理数据的权限的MOI,上述MOI#3即为第二网元不具备获取管理数据的权限的MOI。本申请中也将第二网元不具备获取管理数据的权限的管理对象实例称为第二管理实例。因此该示例中的MOI#3也称为第二管理对象实例。
步骤303,第一网元从第一管理对象实例获取第一网络切片业务标识对应的管理数据。
这里的第一网络切片业务标识对应的管理数据,也可以称为第一网络切片业务标识对 应的网络切片业务的管理数据。
基于该步骤,第一网元是从第一管理对象实例获取与第一网络切片业务标识对应的管理数据,而没有获取该第一管理对象实例中的其他管理数据,因而实现了不同网络切片业务标识对应的管理数据之间的隔离,有利于数据安全性和隐私性。
比如,针对上述示例,则第一网元获取的管理数据如下:
(1)第一网元从MOI#1获取S-NSSAI#1对应的管理数据;
(2)第一网元从MOI#2获取S-NSSAI#1对应的管理数据;
(3)第一网元从MOI#1获取S-NSSAI#2对应的管理数据。
可以看出,MOI#1中包括了S-NSSAI#1、S-NSSAI#2和S-NSSAI#3分别对应的管理数据,第一网元只获取了其中的S-NSSAI#1和S-NSSAI#2对应的管理数据,并没有获取S-NSSAI#3对应的管理数据。MOI#2中包括了S-NSSAI#1、S-NSSAI#3和S-NSSAI#4分别对应的管理数据,第一网元只获取了其中的S-NSSAI#1对应的管理数据,并没有获取S-NSSAI#3和S-NSSAI#4分别对应的管理数据。
即本申请中,获取管理数据的粒度为:网络切片业务标识粒度,实现了数据的精细化划分,有利于数据安全。
步骤304,第一网元向第二网元发送管理数据。相应地,第二网元可以接收到该管理数据。
基于上述实施例,第二网元在请求获取管理数据时,获取到的是网络切片业务标识粒度的管理数据,即获得与自身订购切片业务相关的管理数据,实现了不同租户之间的数据隔离,有利于数据的安全性和隐私性。
针对图3所示的实施例,下面结合不同应用场景进行具体说明。
场景1,性能测量。
基于该场景,上述步骤301的请求消息用于请求创建性能测量任务,该性能测量任务测量管理对象实例中的管理数据。
该场景中,上述步骤301的请求消息包括租户标识和上述至少一个管理对象实例。
上述步骤303具体为:第一网元根据第一网络切片业务标识,为第一管理对象实例对应的性能测量任务设置测量子项,并创建性能测量任务,该性能测量任务用于测量第一管理对象实例中的、与第一网络切片业务标识对应的网络切片业务的管理数据,然后第一网元从第一管理对象实例接收性能测量任务对应的性能测量结果,该性能测量结果为测量子项的管理数据。
基于该场景,可选的,在步骤303之后,还可以包括以下步骤:第一网元向第二网元发送响应消息,该响应消息包括创建的性能测量任务的标识和至少一个管理对象实例中的第二管理对象实例,其中,第二网元不具备获取第二管理对象实例的管理数据的权限,该第二管理对象实例即为未获得授权的管理对象实例。参考前述示例,上述MOI#3即为第二管理对象实例。
需要说明的是,若不存在第二管理对象实例,则该响应消息中不需要携带第二管理对象实例。如果对于所述至少一个管理对象实例中的每一个管理对象实例,所述第二网元都不具备获取其管理数据的权限,则创建的性能测量任务失败,所述第一网元向所述第二网元发送响应消息不包含创建的性能测量任务的标识,只包含第二管理对象实例。
场景2,订阅告警信息。
基于该场景,上述步骤301的请求消息用于请求创建告警信息订阅任务,该告警信息订阅任务用于订阅管理对象实例中的管理数据。该请求消息还指示了第一过滤器(filter)参数,第一过滤器参数用于确定至少一个管理对象实例的告警信息,即管理对象实例的告警信息满足第一过滤器参数指定的判断标准后,就获取这个告警信息。
该第一过滤器参数用于选取参数满足指定的过滤约束条件的告警信息,例如过滤约束条件包括告警的级别大于等于指定级别,告警事件类型为通信错误类型告警或服务质量告警,告警发生的时间在指定时间段内,等等。
该场景中,请求消息中携带的内容可以有多种不同实现方法,下面列举几种。
实现方法1,请求消息携带租户标识、至少一个管理对象实例和第一过滤器参数。
此时,该第一过滤器参数用于对该至少一个管理对象实例中的告警信息进行过滤。
实现方法2,请求消息携带租户标识和至少一个管理对象实例,未携带第一过滤器参数。
当请求消息未携带第一过滤器参数时,隐含指定第一过滤器参数为空,此时第一过滤器参数未执行过滤操作,或者理解为第一过滤器参数过滤的告警信息为上述至少一个管理对象实例的所有的告警信息。
实现方法3,请求消息携带租户标识和第一过滤器参数,未携带管理对象实例。
当请求消息未携带管理对象实例时,隐含指定针对所有的管理对象实例获取告警信息,此时,第一过滤器参数是对所有的管理对象实例的告警信息进行过滤。
实现方法4,请求消息携带租户标识,未携带第一过滤器参数和管理对象实例。
当请求消息未携带第一过滤器参数和管理对象实例时,隐含指定第一过滤器参数为空,且隐含指定针对所有的管理对象实例获取告警信息,此时第一过滤器参数未执行过滤操作,或者理解为第一过滤器参数过滤的告警信息为所有管理对象实例的告警信息。
基于该场景2,上述步骤303具体为:第一网元根据第一网络切片业务标识和第一过滤器参数确定第二过滤器参数,并创建告警信息订阅任务,告警信息订阅任务对应第二过滤器参数,第二过滤器参数用于获取第一管理对象实例中的与第一网络切片业务标识对应的告警信息;第一网元从第一管理对象实例接收告警信息订阅任务对应的告警信息,告警信息为管理数据。
其中,第一网元根据第一网络切片业务标识和第一过滤器参数确定第二过滤器参数,比如可以是:第一网元在第一过滤器参数中添加第一网络切片业务标识,得到第二过滤器参数。或者理解为:第二过滤器参数是满足第一过滤器参数指定的判断标准并且告警包含第一网络切片业务标识。
场景3,查询告警信息。
基于该场景,上述步骤301的请求消息用于请求查询告警信息,该请求消息还指示了第一过滤器(filter)参数,第一过滤器参数用于确定至少一个管理对象实例的告警信息,即管理对象实例的告警信息满足第一过滤器参数指定的判断标准后,就获取这个告警信息。
该场景中,请求消息中携带的内容可以有多种不同实现方法,也可以包含上述场景2中的四种不同实现方法,具体可以参考前述描述。
基于该场景3,上述步骤303具体为:第一网元根据第一网络切片业务标识和第一过滤器参数确定第二过滤器参数;第一网元根据第二过滤器参数,从第一管理对象实例获取第一网络切片业务标识对应的告警信息,告警信息为管理数据。其中,第一网元根据第一 网络切片业务标识和第一过滤器参数确定第二过滤器参数,比如可以是:第一网元在第一过滤器参数中添加第一网络切片业务标识,得到第二过滤器参数。或者理解为:第二过滤器参数是满足第一过滤器参数指定的判断标准并且告警包含第一网络切片业务标识。
需要说明的是,上述场景3与场景2的不同之处,主要在于:场景2是通过订阅告警任务的方式获取告警信息,当满足第二过滤器参数的条件时,则第一管理对象实例会向第一网元发送告警信息,从而第一网元可以每隔一段时间将该段时间订阅到的告警信息发送至第二网元,或者也可以是第一网元接收到告警信息后立即发送至第二网元。而场景3是通过查询的方式获取告警信息,即第一网元基于第二网元的请求,立即从第一管理对象实例中获取满足第二过滤器参数条件的查询结果,该查询结果中包含告警信息,然后第一网元将查询结果发送给第二网元。
下面结合一个具体示例,对图3实施例进行说明。如图4所示,为本申请提供的一个网络示例图。运营商部署了两个网络切片实例,即NSI#1和NSI#2。三个租户订购了运营商的网络切片业务,分配的网络切片业务标识分别为S-NSSAI#1、S-NSSAI#2和S-NSSAI#3。UE1是租户1的终端设备,使用S-NSSAI#1接入网络切片实例NSI#1,和数据网络DN1通信。UE2是租户2的终端设备,使用S-NSSAI#2接入网络切片实例NSI#2,和数据网络DN2通信。UE3是租户3的终端设备,使用S-NSSAI#3接入网络切片实例NSI#2,和数据网络DN3通信。运营商的网络管理系统管理上述网络切片、网络功能和通信业务。租户的系统或设备作为管理数据请求者,运营商的管理系统作为管理服务提供者。管理数据的请求者通过调用管理服务提供者提供的管理服务,获得自身订购网络切片相关的管理数据,包括性能统计数据或告警信息等。
以下图5、图7和图8所示的管理数据的获取方法,均是基于图4所示的具体示例进行说明的。
如图5所示,为申请提供的又一种管理数据的获取方法流程示意图。在图5所示的系统交互中,租户订购的网络切片通信业务会由通信业务管理功能(Communication Service Management Function,CSMF)或商业支撑系统(Business Support System,BSS)管理并记录。CSMF或BSS会记录租户标识(tenant ID),以及租户订购的网络切片业务标识,即S-NSSAI。也就是,租户标识和S-NSSAI的映射关系由CSMF或BSS管理,这个对应关系可能存储在CSMF或BSS内(步骤500),在需要的时候提供给管理服务提供者(如图中步骤500b),并进一步存储在管理服务提供者;也可能存储在数据库(如MIB、NRM信息库或业务发放管理数据库)中(如图中步骤500a),管理服务提供者可以在需要时直接访问数据库获得该映射关系。
该方法包括以下步骤:
步骤501,管理数据请求者(以图4中的租户2为例)向运营商网络管理系统中的管理服务提供者发送创建性能测量任务的请求消息,请求消息中携带了租户2的标识,管理对象实例的列表(MOI_list),性能测量类型等参数。
示例性的,管理对象实例的列表包含了AMF和下一代无线接入网(Next Generation Radio Access Network,NG-RAN)的中心单元(Central Unit,CU)、以及UPF1的MOI。
示例性的,性能测量类型参数包括:AMF的平均注册用户数量、CU的小区分组数据汇聚层协议业务数据单元(Packet Data Convergence Protocol Service Data Unit,PDCP SDU) 上行或下行数据量、以及UPF1的建立会话的数量。
作为示例,该请求消息例如可以是createMeasurementJob消息。
步骤502,管理服务提供者根据收到的创建性能测量任务的请求消息中的租户标识,查询数据库(如步骤502a所示)获得管理数据请求者对应的一到多个S-NSSAI,即租户2订购的网络切片业务标识S-NSSAI#2;或者,管理服务提供者查询从CSMF或BSS获得的租户标识和S-NSSAI的映射关系,得到管理数据请求者对应的一到多个S-NSSAI(如步骤502b所示)。
步骤503,管理服务提供者查询数据库,判断管理数据请求者对应的一到多个S-NSSAI是否在请求消息的管理对象实例的属性或下级属性所包含的S-NSSAI列表中。
如图6所示,为3GPP标准定义的部分管理对象的资源模型。
如果管理对象实例是网络切片实例(NetworkSlice),则包含S-NSSAI的属性层级为serviceProfileList/serviceProfile/sNSSAIList,其中serviceProfileList是网络切片实例的通信业务描述列表,其包含了一到多个通信业务描述serviceProfile。在每个通信业务描述serviceProfile中包含有此通信业务相关的S-NSSAI的列表,其包含一到多个网络切片业务标识S-NSSAI。
如果管理对象实例是子网切片实例(NetworkSliceSubnet),则包含S-NSSAI的属性层级为是sliceProfileList/sliceProfile/sNSSAIList,其中sliceProfileList是网络切片实例的特征描述列表,其包含了子网切片归属的一到多个网络切片实例描述sliceProfile。在每个网络切片实例描述中sliceProfile包含有此网络切片业务相关的S-NSSAI的列表,其包含一到多个网络切片业务标识S-NSSAI。
如果管理对象实例是网络功能(Network Function),例如AMF、SMF、UPF、下一代无线蜂窝网络(Next-generation Cell,NRCell)的CU和DU等,它们都具有sNSSAIList属性,其中包含了一到多个S-NSSAI,表明该网络功能支持处理的一到多个网络切片的业务。
例如,步骤501的请求消息中管理对象的列表包含了AMF、CU和UPF1,管理服务提供者确认步骤502获得的管理数据请求者对应的某个S-NSSAI在AMF的sNSSAIList属性和CU的sNSSAIList属性中,但是不在UPF1的sNSSAIList属性中。
如果请求者对应的所有S-NSSAI都不在管理对象实例或下级属性的sNSSAIList属性中,则判断请求者不具备获取管理对象实例的管理数据的权限,将其从管理对象实例列表中去掉。例如管理数据请求者对应的是S-NSSAI#2,而S-NSSAI#2不在UPF1的sNSSAIList属性中,于是确定管理数据请求者不具备获得UPF1的管理数据的权限,于是将UPF1从管理对象列表中去掉。
如果请求者对所有管理对象实例都不具备获得管理数据的权限,则直接执行步骤506,向管理数据请求者返回创建测量任务失败的响应消息,其中携带了未授权的管理对象实例,例如UPF1;否则,继续执行步骤504,对具备获得管理数据的权限的管理对象实例,例如AMF和CU,准备性能测量任务,但是在后续的步骤506中仍然会携带未授权的管理对象实例(如UPF1)。
需要说明的是,本发明还可以包括网络切片实例(NetworkSlice)和子网切片实例(NetworkSliceSubnet)直接包含sNSSAIList属性的情况,即sNSSAIList属性的层级类似于网络功能(Network Function),此时处理方法同网络功能。
通过该步骤503,可以确定上述请求消息中的每个S-NSSAI对应的允许访问管理数据的管理对象实例。
步骤504,管理服务提供者使用步骤503筛选后的管理数据请求者对应的一到多个S-NSSAI为管理对象实例的性能测量任务设置测量子项。
例如,使用管理数据请求者对应的S-NSSAI#2为AMF的平均注册用户数量设置S-NSSAI#2作为测量子项,为CU的小区PDCP SDU上行或下行数据量设置S-NSSAI#2作为测量子项。也就是只为管理数据请求者提供S-NSSAI#2标识的网络切片的AMF的平均注册用户数量和CU的小区PDCP SDU上行或下行数据量的子统计项,而不是AMF或CU的整体统计项。
例如,在步骤501中请求的测量类型为3GPP TS 28.552中定义的RM.RegisteredSubNbrMean,即注册管理(Register Management,RM)测量类的平均注册用户数量测量类型,经过步骤504处理后,用于创建测量任务的测量类型变为RM.RegisteredSubNbrMean.SNSSAI,即注册管理测量类的注册用户数量测量类型的网络切片测量子类型,它是以S-NSSAI#2标识的网络切片相关的AMF的平均注册用户数量的统计子项。
步骤505,管理服务提供者使用步骤504得到的子统计项为管理数据请求者创建性能测量任务,即请求者对应的一到多个S-NSSAI标识的网络切片相关的子统计项创建性能测量任务,该性能测量任务收集的性能数据都是管理数据请求者能够授权获得的。
步骤506,管理服务提供者向管理数据请求者返回创建性能测量任务的响应消息。
如果创建任务成功,就会携带性能测量任务的标识。如果管理数据请求者不具备获得请求消息中某管理对象实例(即为图3实施例的第二管理对象实例)的管理数据的权限,这个管理对象实例的MOI就会携带在不支持列表中。如果没有成功创建任何测量任务,任务状态就会设置为创建失败。
步骤507,管理服务提供者定期或以事件触发方式收集管理对象实例的性能测量数据。
步骤508,管理服务提供者将收集的测量数据按记录的测量任务生成测量结果,也就是管理数据请求者对应的一到多个S-NSSAI标识的网络切片相关的性能测量子项作为测量任务的测量结果。
步骤509,管理服务提供者将性能测量结果定期或以事件触发方式发送给管理数据请求者。
需要说明的是,如果管理数据请求者对应多个S-NSSAI,例如S-NSSAI#2和S-NSSAI#5,最终创建的性能测量任务中将包含分别以这些S-NSSAI区分的多个统计子项,例如以S-NSSAI#2标识的网络切片相关的AMF的平均注册用户数量的统计子项和以S-NSSAI#5标识的网络切片相关的AMF的平均注册用户数量的统计子项。
基于上述实施例,能够自动验证管理数据请求者是否被授权获得管理对象实例的性能测量数据,并且能够确定被授权的上述管理数据的范围(即哪些网络切片相关的性能测量数据)。能够自动将管理数据请求者没有订购网络切片的性能测量数据从管理数据中过滤掉,在合理的权限范围内向第三方开放性能测量数据。根据管理请求者对应的S-NSSAI是否包含在管理对象实例的属性中,判断管理数据请求者是否具备获取管理对象实例的管理数据的权限;根据管理数据请求者对应的S-NSSAI为性能测量任务设置测量子项,将管理数据请求者对应S-NSSAI的网络切片子项性能测量数据作为性能测量结果,自动将管理 数据请求者没有订购网络切片的性能测量数据从管理数据中过滤掉。
如图7所示,为申请提供的又一种管理数据的获取方法流程示意图。该实施例的场景类似于图5实施例的场景。该方法包括以下步骤:
步骤701,管理数据请求者向身份认证实体请求身份鉴权。
身份认证实体可以为3GPP TS 28.533中定义的开放控制管理功能或其它身份认证的实体。身份认证实体在对请求者的身份鉴权过程中能够确认请求者为某个特定租户,即请求者确实持有某个租户标识;身份认证实体还可能根据请求者身份鉴权的结果,为管理数据请求者发放一个令牌,持有该令牌能够被允许调用管理服务提供者对外开放的管理服务或API(Application Programming Interface,应用编程接口),该令牌中包含有租户标识。
步骤702,运营商网络管理系统中的管理服务提供者接收到管理数据请求者发来的创建性能测量任务的请求消息。
请求消息中携带的租户2的标识为订购的网络切片业务标识,即S-NSSAI#2。请求消息可能是经过身份认证实体转发到管理服务提供者的,此时身份认证实体已经在鉴权过程中确认请求者的租户身份就是S-NSSAI#2或者租户身份对应S-NSSAI#2。如果请求消息是直接从管理数据请求者发送来的,S-NSSAI#2携带在访问令牌中,管理服务提供者会对此令牌进行验证,验证结果会确认管理数据请求者的租户身份就是S-NSSAI#2或者租户身份对应S-NSSAI#2。请求消息中的其它参数同图5实施例。
管理服务提供者通过请求消息中的租户标识,获得管理数据请求者对应的S-NSSAI,即S-NSSAI#2。
步骤703至709,同图5实施例的步骤503至步骤509,可参考前述描述。
需要说明的是,该实施例中,步骤702的请求消息中的租户标识也可以不是订购的网络切片业务标识,则图7实施例也可以像图5实施例那样,通过类似步骤502a或步骤502b的方式获取到租户标识对应的至少一个网络切片业务标识。
基于上述实施例,能够自动验证管理数据请求者是否被授权获得管理对象实例的性能测量数据,并且能够确定被授权的上述管理数据的范围(即哪些网络切片相关的性能测量数据)。能够自动将管理数据请求者没有订购网络切片的性能测量数据从管理数据中过滤掉,在合理的权限范围内向第三方开放性能测量数据。根据管理请求者对应的S-NSSAI是否包含在管理对象实例的属性中,判断管理数据请求者是否具备获取管理对象实例的管理数据的权限;根据管理数据请求者对应的S-NSSAI为性能测量任务设置测量子项,将管理数据请求者对应S-NSSAI的网络切片子项性能测量数据作为性能测量结果,自动将管理数据请求者没有订购网络切片的性能测量数据从管理数据中过滤掉。
如图8所示,为申请提供的又一种管理数据的获取方法流程示意图。图4中的租户2作为管理数据请求者,向运营商网络管理系统中的管理服务提供者发送订阅UPF的告警信息的请求消息,希望获得图4中UPF2、UPF3和UPF4的告警信息。管理数据请求者的身份鉴权的过程类似图7实施例,不再赘述。
该方法包括以下步骤:
步骤801,管理服务提供者接收来自管理数据请求者发送的告警订阅请求消息。
其中,该告警订阅请求消息携带内容包括:
租户2的标识:S-NSSAI#2;
管理对象实例:UPF2、UPF3和UPF4的MOI;
第一过滤器参数:事件类型(eventType)等于Communications Alarm。
步骤802,管理服务提供者查询数据库,判断管理数据请求者对应的一到多个S-NSSAI是否在请求消息的管理对象实例的属性或下级属性所包含的S-NSSAI列表中。
例如,管理数据请求者对应的S-NSSAI#2在UPF2和UPF3的sNSSAIList属性中,但是不在UPF4的sNSSAIList属性中。如果管理数据请求者对应的S-NSSAI不在管理对象实例的sNSSAIList属性中,则确定管理数据请求者不具备获得管理对象实例的管理数据的权限,将该管理对象实例从待创建的告警订阅任务中剔除掉。如果管理数据请求者对所有管理对象实例都不具备获得管理数据的权限,则直接执行步骤805,向管理数据请求者返回创建订阅任务失败消息,其中可以携带了未授权的管理对象实例(如UPF4);否则,继续执行步骤803,对具备获得管理数据的权限的管理对象实例,例如UPF2和UPF3,准备待创建的告警订阅任务。
步骤803,管理服务提供者在第一过滤器参数中添加管理数据请求者对应的S-NSSAI得到第二过滤器参数,即第二过滤器参数为:eventType等于Communications Alarm并且objectInstance等于S-NSSAI#2,将第二过滤器参数作为待创建的告警信息订阅任务的过滤器。
在本实施例中,第二过滤器参数中包括S-NSSAI#2。
步骤804,管理服务提供者创建告警订阅任务,记录任务的订阅标识。
步骤805,管理服务提供者向管理数据请求者返回告警订阅响应消息,如果任务创建成功,就会携带订阅标识;否则返回订阅失败。
步骤806,管理服务提供者收集管理对象实例产生的告警和事件信息。
例如,参考图4,如UPF4因为过载产生拥塞,以S-NSSAI#3为标识的网络切片通信业务受到影响。受到目的地为DN3的拥塞流量的反向压迫,UPF2发生过载并出现丢包告警,以S-NSSAI#3为标识的网络切片通信业务受到影响;同时UPF2因过载以S-NSSAI#2为标识的网络切片通信业务的处理时延变大,超出了阈值,UPF2产生处理时延超出阈值的告警信息。
步骤807,管理服务提供者使用第二过滤器参数过滤收集的告警信息,过滤后的结果作为该告警订阅任务的告警信息。
具体的,管理服务提供者使用第二过滤器参数过滤步骤806收集的告警信息,UPF4的拥塞告警被过滤掉。UPF2的丢包告警信息因只包含S-NSSAI#3而不包含S-NSSAI#2,也被过滤掉。只有UPF2的处理时延超过阈值的告警因包含S-NSSAI#2被保留在过滤后的结果中,作为告警订阅任务的告警信息。
步骤808,管理服务提供者将过滤后的告警信息按照告警订阅任务发送给订阅告警信息的管理数据请求者,其中携带订阅标识和订阅任务的告警信息。该告警信息即为过滤后的告警信息。
需要说明的是,管理数据请求者也可以使用类似图5实施例的方式而不使用S-NSSAI作为租户标识,或者使用多个S-NSSAI作为租户标识,这样管理服务提供者可以获得管理数据请求者对应的多个S-NSSAI,然后使用这多个S-NSSAI检查管理数据请求对管理对象实例的权限,剔除掉未被授权的管理对象,并将请求者对应的多个S-NSSAI添加到第一过 滤器参数中得到第二过滤器参数。例如,租户3作为管理数据请求者请求订阅告警信息时,假如租户3订购了以S-NSSAI#3和S-NSSAI#4标识的网络切片通信业务,最终更新后的订阅任务的第二过滤器参数包括S-NSSAI#3和/或S-NSSAI#4。
需要说明的是,作为一种可替代实现方式,上述步骤801的告警订阅请求消息也可以替换为获取告警信息列表的请求消息,上述步骤805的告警订阅响应消息替换为告警响应消息。此时,无需执行步骤804。以及,步骤806替换为管理服务提供者主动从第一管理对象实例获取告警信息列表。步骤807替换为使用第二过滤器参数过滤收集的告警信息列表,得到过滤后的告警信息列表。步骤808替换为管理服务提供者向管理数据请求者发送过滤后的告警信息列表。该替代方法与图8实施例的主要区别在于:该替换方法是主动请求查询获取告警信息列表,而图8实施例是通过订阅的方法获取告警信息的。
基于上述实施例,能够自动验证管理数据请求者是否被授权获得管理对象实例的告警事件信息,并且能够确定被授权的上述管理数据的范围(即哪些网络切片相关的告警事件信息)。能够自动将管理数据请求者没有订购网络切片的告警信息从管理数据中过滤掉,在合理的权限范围内向第三方开放告警事件信息。根据管理数据请求者对应的S-NSSAI是否包含在管理对象实例的属性中,判断管理数据请求者是否具备获取管理对象的管理数据的权限。根据租户对应的S-NSSAI为告警订阅任务补充过滤参数,将租户订购的S-NSSAI添加到过滤条件中;告警事件信息按照上述过滤条件过滤后的结果报告给管理数据请求者,将管理数据请求者没有订购网络切片的告警信息从管理数据中过滤掉。
