Description

一种网络切片模板的处理方法及管理设备
本申请要求于2017年9月19日提交中国专利局、申请号为201710847660.7、申请名称为“一种网络切片模板的处理方法及管理设备”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
本申请涉及网络技术领域,具体涉及一种网络切片模板的处理方法及管理设备。
背景技术
随着移动通信的高速发展,数字化转型几乎涉及了所有传统行业。但是,传统蜂窝网络架构只能提供统一的网络服务,难以满足数字化转型浪潮带来的差异性极大的通信需求,包括功能性差异、性能差异。在下一代移动网络中,网络将被抽象为“网络切片”,一个网络切片满足某一类或一个用例的连接通信服务需求,整个第五代移动通信技术(5th-Generation,简称5G)系统由满足不同连接能力的大量网络切片组成。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(quality of service,简称QoS)的连接通信服务,是5G网络的基本能力之一。
其中,网络切片指的是在物理或者虚拟的网络基础设施之上,根据不同的服务需求定制化的、不同的逻辑网络。一个网络切片可以是一个包括了终端、接入网、传输网、核心网和应用服务器的完整的端到端网络,能够提供完整的电信服务,具有一定网络能力;一个网络切片也可以是上述终端、接入网、传输网、核心网和应用服务器的任意组合。例如,针对一个接入网,接入网可能切片,也可能不切片;接入网可能是多个网络切片共用的。
而网络切片实例(network slice instance,简称NSI)是一个真实运行的逻辑网络,能满足一定网络特性或服务需求。一个网络切片实例可能提供一种或多种服务。网络切片实例可以由网管系统创建,一个网管系统可能创建多个网络切片实例并同时对它们进行管理,包括在网络切片实例运行过程中的性能监视和故障管理等。NSI由网管系统创建,一个网管系统可能创建多个NSI并同时对它们进行管理,包括在网络切片实例运行过程中的性能监视、故障管理、修改。
然而,由于NSI的是一个真实运行的逻辑网络,因此其网络构建以及管理上,会具有多项网络性能及网络相关参数,不同的业务实体需求的NSI的网络性能及网络相关参数是不相同的,因此,创建一个NSI的过程较为复杂,且多需要人工进行大量设定才可完成创建。
发明内容
本申请实施例提供了一种网络切片模板的处理方法及管理设备,通过使用和管理网络切片模板,简化NSI的创建的过程。
本申请实施例的第一方面提供一种网络切片模板的处理方法,该方法中,第一管理实体是用于管理通信业务的实体,即提出使用NSI需求的实体;而第二管理实体,则是管理网络切片实例的实体,它能够获取并能管理网络切片模板(network slice template,简称 NST)的实体;其中,第一管理实体会接收到第二管理实体发送的第一NST信息,在该第一NST信息为第二管理实体根据预设管理策略确定的第一NST所包含的全部信息的子集。
可以看出,本申请实施例中,第一管理实体在接收NST的信息时,接收到仅为第二管理实体根据预设管理策略确定的第一NST所包含的全部信息的子集,即按照该预设管理策略,第一管理实体获取的NST的信息不一定是一个NST的全部信息,而可以是部分信息,即,第二管理实体可以按需向第一管理实体开放NST的信息。从而使得在使用NST时,管理上更为灵活,实现适度开放网络信息的目标;此外,由于可发送NST的部分信息也大量节约了第一管理实体和第二管理实体之间的通信资源。
结合本申请实施例的第一方面,在本申请实施例第一方面的第一种实现方式中,第一NST信息具体可以是由第二管理实体先确定在其所支持的所有NST中,可以发送给所述第一管理实体的第一NST,第一NST可以是一个或者多个NST,然后再根据第一NST的开放信息确定所述第一NST所包含的全部信息的子集;该第二管理实体能够获取并管理的NST均具有对应的开放信息,并且对于一个NST来说,不同的开放信息会对应到NST所包含的全部信息的不同子集。从而能够实现对NST的信息进行区分管理,根据第一管理实体的需求、以及网络的开放策略,向第一管理实体开放NST的信息的不同部分,使得NST的信息管理更为灵活且高效。具体地,作为一个举例,NST的开放信息可以指示该NST是否允许开放,允许开放的部分内容。
在一些实施例中,第一管理实体具有对应的等级、类型和标识之中至少一个,并且,第一管理实体的等级、类型和标识之中至少一个与所述开放信息具有对应关系;此时,第二管理实体确定一个第一NST的开放信息具体可以根据第一管理实体的等级、类型和标识之中至少一个确定。此方式中,将第一管理实体的信息与开放信息进行了对应,从而对于同一个第一NST,不同的第一管理实体可能对应到第一NST的不同的开放信息,从而使得不同的第一管理实体在接收第一NST的信息时,接收到的信息可以是不同的。从而能够使得NST对应第一管理实体这类需求网络切片的实体实现分级管理,根据不同的级别开放NST的信息的不同部分,使得NST的管理上更为灵活有效。
在一些实施例中,第一NST包含至少一个NST,此情形下,该方法可包括,第一管理实体根据自身业务需求以及所述第一NST信息从至少一个NST中确定目标NST;接着第一管理便以此目标NST向第二管理实体发送第一创建请求,该第一创建请求用第二管理实体创建NSI,该请求中,携带有用于确定所述目标NST的第一标识。即第一管理实体能够从第一NST信息中的不同NST选择自身需求的NST,并以此发送第一创建请求;能够使得第二管理实体根据该第一标识确认到对应的NST,并按照该NST创建对应的NSI。
在一些实施例中,第一NST信息中还携带有第一NST的可调参数和对应的参数调整范围,此时,第一管理实体在向第二管理实体发送第一创建请求之前,还会根据该第一NST的可调参数和对应的参数调整范围确定目标NST的可调参数的参数值,并将该参数值携带在第一创建请求中;即第一NST的信息中有些是可调参数,第一NST信息中还携带有这些可调参数,从而第一管理实体,不仅要确定目标NST,还要一并确定该可调参数的参数值,第二管理实体根据这些参数值便能够创建对于第一管理实体来说更为满足需求的NSI。
在一些实施例中,NST的可调参数为所述第二管理实体根据所述第一创建请求所创建的NSI的网络特性参数,所述网络特性参数用于指示所述NSI的网络特性和/或NSSI的网络特性,该网络特性参数可以包括连接数、时延、带宽和丢包率中的至少一种。这些参数主要用来描述网络的相关质量。
在一些实施例中,可调参数可以是第二管理实体根据所述第一创建请求所创建的NSI的生命周期管理(lifecycle management,简称LCM)参数,该生命周期管理参数是对应NSI在运行过程中的涉及到的一些第一动作的动作参数,其中,该第一动作可以是该NSI存续期间产生的动作,例如创建、激活、修改、性能监控、故障监控、反激活和终结中等动作,而本申请实施例中对应这些第一动作的动作参数可以包括以下情况:第一种,是否支持第一动作;第二种,第一动作与其它动作之间的执行顺序;第三种,第一动作的具体执行时间,该具体执行时间可以是该第一种作执行的持续时长或者该第一动作触发的时刻;第四种,该动作参数还可以是用于触发第一动作的参数,即当参数达到预设参数阈值时触发第一动作。使得对NSI的管理细化到该NSI的生命周期的各个动作,从而使得第一管理实体能够在知晓该生命周期管理参数的前提下,能够在创建请求中携带一些生命周期管理参数的参数值,从而使得生成的NSI更能对应第一管理实体的需求。
在一些实施例中,第一管理实体接收第二管理实体发出的第一NST信息之前,第一管理实体还会向所述第二管理实体发送获取请求,所述获取请求用于获取第一NST信息。
在一些实施例中,第一管理实体接收所述第一NST信息之后,向NSI用户发送所述第一NST信息,并接收所述NSI用户发送的由该NSI用户选择的目标NST,以及还可以接收由该NSI用户确定的对应该NSI用户选择的目标NST的可调参数的参数值,该目标NST以及该参数值在发送给第一管理实体后,第一管理实体可根据该目标NST或者该目标NST以及该参数值向第二管理实体发送用于创建NSI的创建请求。
本申请实施例第二方面还提供一种网络切片模板的处理方法,该方法中,第二管理实体会接收到第一管理实体发送的第一创建请求,该第一创建请求用于创建NST,该第一创建请求中携带有第二NST的标识;接着,第二管理实体便会根据该标识对应的第二NST创建第一NSI,该第二NST为第二管理实体从获取的NST中选取的目标NST,即该第二NST是第二管理实体能够支持的NST。
可以看出,该第二管理实体能够支持该第二NST的情况下,第二管理实体创建的第一NSI是根据第一管理实体指定的第二NST来创建的,从而一方面,相对于目前的手工方式创建NSI,根据第二NST创建第一NSI能够简化第一NSI的创建过程,能够使用相同的NST创建多个相同类型的NSI。另外,由于创建的第一NSI是由第一管理实体指定的NST(由第一管理实体自行决定,或者由第一管理实体接收到的租户信息决定),因此,第一NSI会更符合第一管理实体的需求。
在一些实施例中,第二管理实体根据所述第二NST的标识所对应的NST创建第一NSI的过程可以是,首先由第二管理实体根据第一NST确定所述第一NSI所包含的网络切片子网实例(network slice subnet instance,简称NSSI),对于一个NSI,该NSI可以包含至少一个NSSI,因此,该第一NSI可以包含至少一个第一网络切片子网实例;接着,第二 管理实体便会向第三管理实体发送第二创建请求,该第二创建请求中包含该NSSI的需求信息,该需求信息能够使得第三管理实体根据该需求信息创建所述第一NSI所包含的NSSI,其中,这些NSSI均为第三管理实体能够支持的NSSI。
在一些实施例中,该方法还包括,第二管理实体确定所述第一NSI包含的NSSI之间的连接关系,通过该连接关系能够唯一确定这些NSSI如何组成一个NSI;在此情形下,该连接关系有两种方式告知给第三管理实体,第一种是NSSI的需求信息中还包含第一NSI包含的NSSI之间的连接关系,第三管理实体在接收到该需求信息后即可获知这些连接关系;第二种是第二管理实体向所述第三管理实体发送第一消息,该第一消息中携带有所述第一NSI包含的NSSI之间的连接关系;该第一消息可以是第二管理实体单独向第三管理实体发送的消息,该第一消息也可以随着需求信息一起发送给第三管理实体。在具有该连接关系的情况下,第三管理实体能够按连接要求,对NSSI进行配置,便于形成NSSI之间的连接关系从而组成NSI。
在一些实施例中,第二管理实体还会确定第一NSI包含的第一NSSI的网络特性参数,这些网络特性参数可包括连接数、时延、带宽和丢包率中的至少一个;具体的,可将第一NSSI的网络特性参数携带在NSSI的需求信息中发送给第三管理实体。在具有该网络特性参数的情况下,第三管理实体能够创建更为精确的第一NSSI。
在一些实施例中,第二管理实体确定所述第一NSI包含的第一NSSI的网络特性参数的具体过程有至少两种方式,一种可以是,第二管理实体根据第一NSI的网络特性参数,以及所述第一NSI的网络特性参数的分解策略,确定第一NSSI的网络特性参数,所述分解策略用于将所述第一NSI的网络特性参数分解为至少一个第一NSSI的网络特性参数;第二种可以是,第二管理实体根据所述第一NSI模板中携带的分解策略确定将所述第一NSI的网络特性参数分解为至少一个第一网络切片子网实例的网络特性参数。该网络特性参数的分解策略可以在第二管理实体本地预设,或者直接携带在第二NST中。
在一些实施例中,该方法还可包括,第二管理实体根据第一NSSI的描述信息确定第一网络切片子网模板(network slice subnet template,简称NSST),第一NST中还携带有该第一NSSI的描述信息,该描述信息包括NSSI类型、NSST的标识以及NSSI的网络特性参数中的至少一个,所述第二管理实体可以通过第一NST直接获得第一NSST的标识,或者根据第一NSSI的描述信息,判断选择一个NSST作为第一NSST;所述由第二管理实体发送给第三管理实体的NSSI的需求信息还包含第一NSST的标识,或者第一NSST的全部/部分信息。
在一些实施例中,描述信息包括NSSI的网络特性参数,作为第二管理实体确定NSSI的网络特性参数第三种方式,所述由第二管理实体发送给第三管理实体的NSSI的需求信息中还包含所述网络特性参数。在一些实施例中,第二管理实体还会根据预设管理策略生成第一NST信息,第一NST信息包括有第一NST所包含的全部信息的子集,其中,NST是第二管理实体获取的、能够支持的NST,接着,第二管理实体会向第一管理实体或第一设备发送所述第一NST信息,该第一管理实体用于管理通信业务,该第一设备用于存储所述第一NST信息。可以看出,第二管理实体可以有选择性的向第一管理实体提供第二管理实体 支持的NST中的全部信息的子集,管理上更为灵活,此外,由于可发送NST的部分信息也大量节约了第一管理实体和第二管理实体之间的通信资源。
在一些实施例中,第二管理实体根据预设管理策略生成第一网络切片模板信息的过程可以是第二管理实体根据第一NST的开放信息确定第一NST所包含的全部信息的子集;第二管理实体中的NST有对应的开放信息,不同的开放信息对应所述第一NST所包含的全部信息的不同子集。对于一个NST来说,不同的开放信息会对应到NST所包含的全部信息的不同子集。从而能够实现对NST的信息进行区分管理,按照第一管理实体的需求向第一管理实体开放NST的信息的不同部分,或者根据第二管理实体保存的本地策略适度开放网络信息,使得NST的信息管理更为灵活且高效。
在一些实施例中,第二管理实体根据所述第一管理实体的等级、类型和标识中的至少一个确定所述第一网络切片模板的开放信息,所述第一管理实体具有对应的等级、类型和标识中的至少一个;所述第一管理实体的等级、类型和标识中的至少一个与所述开放信息具有对应关系。第一管理实体具有对应的等级、类型和标识之中至少一个,并且,第一管理实体的等级、类型和标识之中至少一个与所述开放信息具有对应关系;此时,第二管理实体确定一个第一NST的开放信息具体可以根据第一管理实体的等级、类型和标识之中至少一个确定。此方式中,将第一管理实体的信息与开放信息进行了对应,从而对于同一个第一NST,不同的第一管理实体可能对应到第一NST的不同的开放信息,从而使得不同的第一管理实体在接收第一NST的信息时,接收到的信息可以是不同的。从而能够使得NST对应第一管理实体这类需求网络切片的实体实现分级管理,根据不同的级别开放NST的信息的不同部分,使得NST的管理上更为灵活有效。
在一些实施例中,第一NST包含至少一个NST,所述第一NST信息中携带有第一NST的可调参数和对应的参数调整范围,此时,该方法还可包括:第二管理实体接收第一管理实体发出的第一创建请求,该第一创建请求中携带有第二网络切片模板的标识,以及所述第二NST的可调参数和对应的参数值,该第二NST为所述第一管理实体根据自身业务需求以及所述第一NST信息从所述第一NST包含的至少一个NST中确定要使用的目标NST。由于第一管理实体通过第一NST信息获取了第一NST的可调参数和对应的参数调整范围,因此在第一管理实体选择了对应的目标NST后,还要一并确定该可调参数的参数值,以便于第二管理实体创建更为符合第一管理实体要求的NSI。
在一些实施例中,NST的可调参数为第二管理实体根据第一创建请求创建的网络切片实例的网络特性参数,所述网络特性参数用于指示所述网络切片实例的网络特性和/或网络切片子网实例的网络特性,所述网络特性参数可以包括时延、带宽和丢包率中的至少一种。这些参数主要用来描述网络的相关质量。
在一些实施例中,可调参数可以是第二管理实体根据所述第一创建请求所创建的NSI的生命周期管理参数,NST的可调参数为第二管理实体根据第一创建请求创建的网络切片实例的生命周期管理参数,该生命周期管理参数是对应NSI在运行过程中的涉及到的一些第一动作的动作参数,其中,该第一动作可以是该NSI存续期间产生的动作,例如创建、激活、修改、性能监控、故障监控、反激活和终结中等动作,而本申请实施例中对应这些 第一动作的动作参数可以包括以下情况:第一种,是否支持第一动作;第二种,第一动作与其它动作之间的执行顺序;第三种,第一动作的具体执行时间,该具体执行时间可以是该第一种作执行的持续时长或者该第一动作触发的时刻;第四种,该动作参数还可以是用于触发第一动作的参数,即当参数达到预设参数阈值时触发第一动作。使得对NSI的管理细化到该NSI的生命周期的各个动作,从而使得第一管理实体能够在知晓该生命周期管理参数的前提下,能够在创建请求中携带一些生命周期管理参数的参数值,从而使得生成的NSI更能对应第一管理实体的需求。
在一些实施例中,第二管理实体向所述第一管理实体发送第一NST信息之前,该方法还可包括:
第二管理实体接收所述第一管理实体发送获取请求,该获取请求用于获取所述第一NST信息。
在一些实施例中,该方法还可包括:
第二管理实体根据使用的模板信息,以及已创建的NSI生成第一NSI描述信息和/或第一网络切片实例运行记录;接着,第二管理实体将该NSI的标识和对应的第一NSI描述信息和/或第一NSI运行记录存储至所述第一设备。通过描述信息和运行记录,能够了解NSI在存续过程中的状态以及最新的状态。
在一些实施例中,该方法还可包括:首先,每隔一定周期或当所述NSI的运行参数发生变化时,所述第二管理实体根据NSI的当前运行状态生成第二NSI描述信息和/或第二网络切片实例运行记录;接着,第二管理实体将第一设备内对应所述NSI的标识的第一NSI描述信息和/或第一网络切片实例运行记录更新为第二NSI描述信息和/或第二网络切片实例运行记录。
本申请实施例第三方面还提供一种网络切片模板的处理方法,该方法可包括:
首先,第一管理实体向第一设备发送第一读取请求,该第一读取请求中携带有第二管理实体的标识;接着,第一管理实体从第一设备获取所述第一NST信息,该第一NST信息为所述第二管理实体根据预设管理策略确定并存储在第一设备上的第一NST所包含的全部信息的子集;该第一管理实体用于管理通信业务,该第二管理实体用于管理NSI。该第一设备用于存储第二管理实体发送的各类信息。设置第一设备,能够使得第二管理实体将第一NST信息这类信息存放于第一设备上,在其他具有NSI使用需求实体需要获取NST的相关信息时,无需向第二管理实体发送信息,而仅需从该第一设备上获取相关的信息即可,使得第二管理实体的负载降低,并且由于此过程无需与第一管理实体建立连接,还节省了通信资源。
在一些实施例中,该第一读取请求中还携带有所述第一管理实体的等级、类型和标识中的至少一种,此时,第一管理实体从所述第一设备获取所述第一网络切片模板信息具体可以是,第一管理实体从所述第一设备获取与所述第一管理实体的等级、类型和标识中的至少一种对应的所述第一网络切片模板信息;所述第一管理实体的等级、类型和标识中的至少一种与开放信息具有对应关系,所述第一网络切片模板具有对应的开放信息,不同的开放信息对应所述第一网络切片模板所包含的全部信息的不同子集。

具体实施方式
本申请实施例提供了一种网络切片模板的处理方法及管理设备,通过使用和管理网络切片模板,简化NSI的创建的过程。
为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附 图,对本申请实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”或“具有”及其任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在5G网络中,一个网络切片(network slice)满足某一类或一个用例的连接通信服务需求,5G网络本身便是由满足不同连接能力的大量网络切片组成,从而满足各种不同的服务,一个网络切片所能提供的服务可以由多种功能组成。而网络切片本身便是根据不同的服务需求定制化的、不同的逻辑网络。网络切片可以是一个包括了终端、接入网、传输网、核心网和应用服务器的完整的端到端网络,能够提供完整的电信服务,具有一定网络能力;网络切片也可以是上述终端、接入网、传输网、核心网和应用服务器的任意组合。网络切片可能具有如下一个或多个特性:接入网可能切片,也可能不切片。接入网可能是多个网络切片共用的。不同的网络切片的特性和组成它们的网络功能可能是不一样。
网络功能(network function,简称NF)是网络中的一种处理功能,定义了功能性的行为和接口,网络功能可以通过专用硬件实现,也可以通过在专用硬件上运行软件实现,也可以在通用的硬件平台上以虚拟功能的形式实现。因此,从实现的角度,可以将网络功能分为物理网络功能和虚拟网络功能。而从使用的角度,网络功能可以分为专属网络功能和共享网络功能,具体地,对于多个(子)网络切片实例而言,可以独立地使用不同的网络功能,这种网络功能称为专属网络功能,也可以共享同一个网络功能,这种网络功能称为共享网络功能。
对应于网络切片的NSI是一个真实运行的逻辑网络,能满足一定网络特性或服务需求。一个网络切片实例可能提供一种或多种服务。网络切片实例可以由网管系统创建,一个网管系统可能创建多个网络切片实例并同时对它们进行管理,包括在网络切片实例运行过程中的性能监视和故障管理等。当多个网络切片实例共存时,网络切片实例之间可能共享部分网络资源和网络功能。网络切片实例可能从网络切片模板创建,也可能不从网络切片模板创建。一个完整的网络切片实例是能够提供完整的端到端的网络服务的,而组成网络切片实例的可以是NSSI和/或网络功能。网络功能可以包括物理网络功能和/或虚拟网络功能。本申请实施例中统称物理网络功能和/或虚拟网络功能为网络功能。
针对NSI的创建,目前一般由网络管理系统/网络切片管理系统来创建,其创建方式一种是直接是按照组网需求和网络资源来创建,设计网络切片的结构和网络特性。为了使得创建过程更为便捷,一种被认为可行的方式是通过人工编辑方式逐一生成每个NSI,或者通过人工编辑的方式生成对应NSI的模板以适配不同类别的NSI,在创建NSI时,只要通过人工选择到该模板,便可以根据该模板快速进行NSI的创建,即对于一类较为相似的NSI, 则可以创建一个能够公用的模型,而不同的NSI仅需要通过该模型不同的参数设定即可生成不同的NSI,能够使得NSI的创建过程更为便捷。这种采用公用模型的方式即是本申请实施例的NST,根据一个NST可以生成具有相同特性的不同的NSI,这些NSI在功能上可以是大体相同的,但是由于各自的网络特性的不尽相同,可适用于不同的网络场景中。
目前,针对NST这类模型或者模板,默认的方式是采用人工方式生成,或者通过人工来选择,缺乏一个自动化的管理、使用流程,并且该NST目前并没有统一的定义,因此一个NST具体需要包含哪些内容,以及该NST具体如何使用,由网络中哪种实体来管理,哪种实体来使用也没有相应的说明。对此,本申请实施例给出一种网络切片模板的处理方法、管理设备和存储设备来解决NST的处理过程,包括如何使用NST生成一个NSI的过程,如何对NST进行管理等。
本申请实施例对NST进行处理的架构可参阅图1,图1是本申请实施例的网络切片模板的处理方法的架构示意图。其中,包括需求或者使用NSI的第一管理实体101,以及对NSI进行管理的第二管理实体102。具体的,该第一管理实体101可以使用各种不同的NSI的实体,第二实体可以是用于管理NSI和支持一些NST的管理实体。举例来说,第一管理实体101可以是通信业务管理功能实体(communication service management function,CSMF),而第二管理实体102则可以是网络切片管理功能实体(network slice management function,简称NSMF)。其中,该CSMF主要负责将运营商和/或第三方客户的通信服务需求转化为对网络(切片)的需求,并通过和NSMF这类用于管理NSI的实体之间的接口向NSMF发送对网络切片的需求(如创建NSI请求、终结NSI请求、修改NSI请求等),从NSMF中获取网络切片的管理数据(如性能、故障数据等),生成运行于网络切片实例之上的通信业务的管理数据,接收运营商和/或第三方客户对网络切片管理数据和/或通信业务的管理数据的订阅需求等。而NSMF主要负责接收CSMF发送的网络切片需求,对网络切片实例的生命周期、性能、故障等进行管理(以下将生命周期、性能、故障管理简称管理),编排网络切片实例的组成,分解网络切片实例的需求为各网络切片子网实例和/或网络功能的需求,向各NSSMF发送网络切片子网实例管理请求。
此外,对于一个网络切片来实例说,由于可以由NSSI和网络功能组成,因此,在生成NSI时,需要对NSI的需求进行分解,得到生成该NSI所需的NSSI,接着,便会生成NSSI,而后由NSSI的组合完成NSI的生成。具体的,请参阅图2,图2是本申请实施例的网络切片模板的处理方法的架构示意图,该架构区别于图1所示的架构来说,增加一个第三管理实体103,该第三管理实体103主要用于管理NSSI,它支持根据一些NSST生成NSSI。举例来说,第三管理实体103可以是网络切片子网管理功能(network slice subnet management function,简称NSSMF),此时,该NSSMF主要负责接收NSMF发送的网络切片子网需求,对网络切片子网实例进行管理,编排网络切片子网实例的组成,分解网络切片子网实例的需求为各网络功能和/或嵌套网络切片子网实例的需求,可能向其他NSSMF发送嵌套网络切片子网实例管理请求。
此外,需要说明的是,虽然NSI可由多个NSSI组成,但是NSI和NSSI的生命周期是 各自独立的,即终结一个NSI并不等于一定要终结一个NSSI,但是NSI和NSSI存在着管理上的关联,例如创建一个NSI可能需要创建新的NSSI,修改一个NSI可能需要修改一个NSSI。
下面对本申请中所使用的NST所包含的内容进行说明,即NST说明。
本申请实施例中的NST可包含多种内容,举例来说,本申请实施例的NST可包括:
1、NST的标识,该标识可以是一个数字,或者字符描述,索引到某一个NST,对于支持该NST的管理实体,根据该NST的表示便可获取到相应的NST。
2、NSI的类型,该类型有多种,例如大规模连接物联网(Massive Internet of Things,简称MIoT)、增强移动宽带(enhanced mobile broadband,简称eMBB)、低时延高可靠连接(ultra reliable and low latency communications,简称URLLC)、WTTx(wireless to the X)等。WTTx是一种通过无线宽带技术来提供家庭宽带服务的技术,WTTx利用部署的4G基站,运营商不用上门安装,用户在营业厅自行领取终端设备,回家后即可通过4G基站享受高速率的宽带接入服务,极大降低了运维成本。
本申请中的NST还可包括如下部分:
1、NSI的组成部分:例如关于NSSI的描述信息(如NSST,NSSI类型,NSSI的网络特性参数等),关于NF的描述信息。
2、NSI的组成部分之间的连接关系:例如NSSI之间的连接关系,NF之间的连接关系。
3、NSI的特性(也可称为属性、配置、参数等):即一些网络特性及相关的参数。例如NSI支持的带宽范围,NSI支持的数据传输时延(单向、双向)范围,NSI支持的数据传输可靠性范围,NSI支持的移动性类型(如移动速度和传输速率/带宽的对应等)。
4、NSI生命周期相关信息:NSI的生命周期管理流程包括创建、激活、修改(扩缩容、增加/删除功能等)、注销、终结等;NSI生命周期管理流程的执行策略,例如:激活动作在创建动作之后执行,是否支持扩缩容,容量达到一定阈值后启动扩缩容等信息。
需要说明的是,NST包含的信息,部分不可改,部分可设置。例如NSI的标识、类型等固有属性不可改变;还有一些其它的信息可以被按需设定:NSI的特性(配置)可允许改变,例如NST中说明NSI支持的带宽范围是<x~y>,并且指出该参数可配置,从而该参数可以被配置为x~y之间的一个值,又如NSI支持的移动性类型为A、B、C类,默认为A,但是可以选择其中一类。NSI的生命周期相关信息,例如可以设置扩缩容的阈值、激活/注销的时间等。
实施例1
下面对采用上述架构的本申请实施例的网络切片模板的处理方法进行说明,请参阅图3,图3是本申请实施例的网络切片模板的处理方法的一个实施例图,如图3所示,该方法中包括第一管理实体和第二管理实体,该方法可包括:
301、第一管理实体向第二管理实体发送第一获取请求。
其中,该获取请求用于获取第一NST信息,该第一获取请求是在第一管理实体需要请求创建NSI的情况下发出的,由于第二管理实体是能够进行NSI管理的实体,因此向该第二实体发送第一获取请求即可获得相应的第一NST信息。其中,第一NST信息可以包含至少一个第一NST中每个NST的全部信息的子集。
需要说明的是,该步骤301仅为使得第二管理实体执行步骤302和步骤303的一种方式,第二管理实体也可以自行决定何时执行步骤302,例如在完成组网后初始化的过程中自行执行步骤302和步骤303,即根据实际的使用场景的不同而有所不同,具体是否执行该步骤301不作限定。
302、第二管理实体根据预设管理策略生成第一NST信息。
其中,该第一NST信息中包括至少一个第一NST中每个NST的全部信息的子集,对于一个NST来说,其包含的全部信息可以参见本申请实施例的NST说明的内容。一个NST的全部信息的子集可是该全部信息中的部分信息,也可以是该全部信息,具体的可根据第二管理实体实行的策略的不同而不相同。
下面对本申请实施例中第二管理实体根据预设管理策略生成第一NST信息进行说明。本申请实施例中,第二管理实体针对第二管理实体能够获取到的NST,及第二管理实体能够从其他实体或者网络或者直接从自身存储中获取的NST,这些NST均为第二管理实体能够支持的NST。对于这类NST,第二管理实体会设定相应的开放信息,该开放信息意味着针对该NST可以给其他如第一管理实体的NST的信息的开放程度。举例来说,一个NST可包含6种信息,分别为信息1、信息2、信息3、信息4、信息5和信息6。开放信息例如包括三种,第一种开放信息对应信息1和信息2;第二种开放信息对应信息1、信息2、信息3和信息5;第三种开放信息包括信息1、信息2、信息5和信息6。可以看出,对于一个NST来说,不同的开放信息能够对应到一个NST的全部6种信息的不同子集。例如,第二管理实体的预设管理策略是按照一种开放信息进行开放,即,此情形下,该第一NST信息中的每个NST所包含的仅为信息1和信息2。当然,第二管理实体也可以按照其他开放信息来进行信息的开放。开放信息还可以指示该NST的信息全部都不允许,或者也可以是全部允许开放。
举例来说,以本申请实施例中的NST所包含的NST的标识、NSI的类型、NSI的组成部分、NSI的组成部分之间的连接关系、NSI的特性以及NSI生命周期相关信息为例。NST的全部信息的子集可以是如下多种情况中的一种:
(1)NST标识以及NSI类型。
(2)NST标识、NSI类型以及NSI包含的NSSI。
(3)NST标识、NSI类型以及NSI包含的NSSI和NSSI之间的连接关系。
(4)NST标识、NSI类型、NSI包含的NSSI、NSSI之间的连接以及NSI的特性。
(5)NST标识、NSI类型、NSI包含的NSSI、NSSI之间的连接、NSI的特性以及NSI的生命周期管理流程信息。
需要说明的是,上述情况并非本申请中的所有情况,本申请中的NST包含的多种信息可根据需要设置对应的开放信息来开放全部信息中的不同部分,此处不再赘述。此外,第二管理实体还可以给NST设定固定开放的信息,即在第二管理实体支持该NST起便已固定设置。
可选的,对于第一管理实体,每个第一管理实体可以具有对应的等级、类型和标识之中至少一个参数,该开放信息还可以和这些参数之中的至少一种进行对应。第一管理实体的等级可以是根据其具体所在的网络和在网络中的层级来确定的,当然也可以是由第二管理实体来确定的等级;第一管理实体的类型则尤其所具有的功能来确定;对于第一管理实体的标识,是在第二管理实体中具有唯一对应关系的标识,从而第二管理实体可以根据该标识为不同的第一管理实体设定不同的开放信息。在此情形下,第二管理实体在生成第一NST信息之前,还会对第一管理实体对应的开放信息进行确定,具体的,在步骤302之前,该方法还可包括:
第二管理实体根据第一管理实体的等级、类型和标识之中至少一个确定第一管理实体的开放信息。
此时,步骤302具体可为,所述第一网络切片模板的开放信息确定所述第一网络切片模板所包含的全部信息的子集。
303、第二管理实体向第一管理实体发送第一NST信息。
其中,第二管理实体在按照预设管理策略生成第一NST信息后,便会将其发送给第一管理实体。
304、第一管理实体根据第一NST信息向第二管理实体发送第一创建请求。
其中,该第一创建请求用于创建NSI。根据第一NST信息中所包含的内容不同,第一管理实体发送不同的第一创建请求。
可选的,该第一NST信息中包含至少一个第一NST的全部信息的子集,即第二管理实体向第一管理实体提供了多个NST的信息;此时,该步骤304可包括:
第一管理实体从第一NST信息中包含的第一NST中确定目标NST,该目标NST即是第二管理实体提供的多个NST中的一个。
第一管理实体向第二管理实体发送第一创建请求中包含目标NST的标识。从而第二管理实体在接收到该第一创建请求后,便能够根据该目标NST的标识找到对应的网络切片模板来创建NSI。
可选的,由于NST所包含的信息中还可能有一些可调参数和对应的可调参数范围,这些可调参数可以由第一管理实体来确定其值,此时,第一NST信息中的第一NST的信息便会包括可调参数和可调参数范围。在此情况下,步骤304具体可以是首先从第一NST信息中包含的第一NST中确定目标NST;
接着,第一管理实体根据目标NST的可调参数和对应的可调参数范围确定目标NST的可调参数的参数值;
最后在生成第一创建请求时,将该可调参数的参数值也携带在第一创建请求中发送给第二管理实体。从而第二管理实体根据这些参数值便能够创建对于第一管理实体来说更为满足需求的NSI。提升NSI的创建效率。
需要说明的是,这些可调参数的参数值若第一管理实体不进行设定,第二管理实体便会按照默认值进行NSI的创建。
举例来说,这些可调参数可以如下参数之中的至少一种。
(1)参数:移动性支持(support mobility),即该网络切片实例所提供的服务能够支持移动的速度;属性:可设置;默认:0km/h;可调整范围:500km/h,100km/h,20km/h,0km/h。
(2)参数:支持的连接数/用户数;属性:可设置;默认:N;可调整范围:N~2N,N为正整数。
(3)参数:业务间隔离;属性:可设置;默认:非隔离;可调整范围:隔离,不隔离。
(4)参数:安全级别;属性:可设置;默认:级别1;可调整范围:1~M,M为整数。
(5)参数:NSI总带宽;属性:可设置;默认:x;可调整范围:x~y Mbps,x和y均为正数。
(6)参数:服务等级协议(service level agreement,简称SLA)或服务级别需求(service level requirement,简称SLR)分解到各个NSSI的方法,以时延为例;属性:可设置;默认:无线接入网(radio access network,简称RAN)部分占50%加上核心网(Core Network,简称CN)部分占50%。可调整范围:RAN占20~80%,CN占20~80%,CN加RAN为100%。
可选的,上述可调参数还可以是生命周期管理参数中的可调参数,此时,第一NST信息中还会包含有这些生命周期管理参数以及对应的可调参数范围。在可调参数为生命周期管理参数中的可调参数时,第一管理实体在接收到第一NST信息后,进行的操作与上述可调参数的操作类似,此处不再赘述。
需要说明的是,该生命周期管理参数中的可调参数可与上述可调参数一并在第一NST信息中包含,也可以在第一NST中仅包含上述可调参数,而不包含生命周期管理参数中的可调参数,亦或是仅包含生命周期管理参数中的可调参数,而不包含上述可调参数。
需要说明的是,该生命周期管理参数是对应NSI在运行过程中的涉及到的一些第一动作的动作参数,其中,该第一动作可以是该NSI存续期间产生的动作,例如创建、激活、修改、性能监控、故障监控、反激活和终结中等动作,而本申请实施例中对应这些第一动作的动作参数可以包括以下情况:第一种,是否支持第一动作;第二种,第一动作与其它动作之间的执行顺序;第三种,第一动作的具体执行时间,该具体执行时间可以是该第一种作执行的持续时长或者该第一动作触发的时刻;第四种,该动作参数还可以是用于触发第一动作的参数,即当参数达到预设参数阈值时触发第一动作。使得对NSI的管理细化到该NSI的生命周期的各个动作,从而使得第一管理实体能够在知晓该生命周期管理参数的前提下,能够在创建请求中携带一些生命周期管理参数的参数值,从而使得生成的NSI更能对应第一管理实体的需求。
其中,NSI的创建、激活、修改、注销、反激活和终结动作的动作参数可以是对应的时间,这些时间可以自行设定,而修改参数还可以包括(对NSI的扩缩容、增加或删除NSI中的NSSI或者NF,又或者是修改NSI的拓扑等操作)。例如,对于支持扩缩容可以是在容量达到对应的阈值T后,即可进行扩缩容,该T可以自行设定,该T若为容量上限值,则可表示容量达到阈值T后,便可以进行扩容操作,该T若为容量下限值,则可表示容量到达该阈值T后,进行缩小容量操作。对于性能监控和故障监控的动作可以设定监控周期等。可以看出,对生命周期管理的参数的设定能使得对NSI的管理细化到该NSI的生命周期的各个动作,从而使得第一管理实体能够在知晓该生命周期管理参数的前提下,创建更为符合第一管理实体需求的NSI。
需要说明的是,步骤304中,第一管理实体向第二管理实体发送的第一创建请求虽然是第一管理实体生成的,但是第一创建请求中包含的目标NST,以及还可能包含的可调参数的参数值不一定是由第一管理实体确定的,而是第一管理实体从其他NSI用户获取的;具体的,该目标NST以及该参数值的获取过程可以是,首先由第一管理实体向其他NSI用户发送给第一NST信息后,接着该NSI用户读取该第一NST信息中的内容,并确定目标NST或者目标NST以及参数值后,将目标NST或者目标NST以及参数值反馈给第一管理实体。
举例来说,以NSI用户为想要购买NSI的租户为例,该租户例如一个虚拟运营商,该租户希望从运营商租用给一个逻辑网络,即NSI,该运营商的管理系统中可包含第一管理实体;具体的过程可以是,首先该租户通知给运营商需要租用一个逻辑网络,接着,运营商的第一管理实体在获取到第一NST信息后,可将该第一NST信息提供给该租户,该租户可以从该第一NST信息中包含的多个NST中按照目标需求选择对应的目标NST,同时,若该第一NST信息中还包括可调参数以及可调参数的调整范围时,还可以由租户确定可调参数的参数值;接着,该租户可将选定的目标NST或目标NST以及参数值发送给第一管理实体,第一管理实体进而可以根据该目标NST或目标NST以及参数值生成第一创建请求,并发送给第二管理实体进行NSI的创建。
实施例2
上面对本申请实施例的网络切片模板的处理方法中NST的全部信息的部分信息的使用进行了说明,下面对本申请实施例的网络切片模板的处理方法进行说明,针对使用NST创建NSI的过程进行说明。本实施例中,第一管理实体和第二管理实体与图3所示实施例类似,即第一管理实体为需求NSI的管理实体,第二管理实体为用于管理NSI以及支持的NST的实体。请参阅图4,图4是本申请实施例的网络切片模板的处理方法的一个实施例图,如图4所示,该方法可包括:
401、第一管理实体向第二管理实体发送第一创建请求。
其中,该第一创建请求中包含NST标识,该NST标识可以是第一管理实体获取的NST信息后得到的目标NST标识,该NST标识可在第二管理实体上唯一标识一个NST,从而使得第二管理实体能够根据该NST标识获取到对应的NST。
需要说明的是,该第一创建请求中还可以包含如图3所示实施例中的可调参数的参数值和/或是生命周期管理参数中的可调参数的参数值。其中,该可调参数的参数值以及生命周期管理参数中的可调参数的参数值的设定过程可参见图3所示实施例中针对步骤304的说明,此处不再赘述。这些设定的参数值会用于步骤402第二管理实体创建NSI的过程中。
402、第二管理实体根据第一创建请求中的NST标识对应的NST创建NSI。
其中,第二管理实体在从第一创建请求中获取到NST标识后,便会依据该NST标识查找对应NST,对于该NST标识,必须是第二管理实体能够支持的NST的NST标识,对于第二管理实体支持的NST,第二管理实体可以从自身存储或者网络或者其他设备获取到该NST,并且能够根据该NST生成NSI。
需要说明的是,第二管理实体根据NST创建NSI的过程可以包括如下步骤之中的部分或者全部。具体的,该步骤402具体可包括图5所示步骤之中的部分或者全部,请参阅图5,图5是本申请实施例的网络切片模板的处理方法中创建NSI的示意图;其中,该过程包括:
501、第二管理实体根据NST和第一创建请求确定组成NSI的NSSI和/或NF。
其中,对于一个NSI,该NSI可以包含至少一个NSSI,因此,该第一NSI可以包含至少一个NSSI,当然还可以包括至少一个NF,或者一个NSI仅有NF组成。本申请实施例中以一个NSI的组成部分包括NSSI为例。
需要说明的是,实际上,一个NSI是由NF的集合所构成,因此一个NSI包括一个或者多个NF,而一个NSSI本质上同样由一个或者多个NF组成。因此,第二管理实体在确定了NST以及第一创建请求后,便可以对NST对应的NSI进行分解,分解成若干个NSSI和/或NF。在确定了组成NSI所必须的NSSI/NF后,第二管理实体可以向相应的第三管理实体发起创建NSSI或者重用NSSI请求,例如若判断NSI需要由3GPP管理的RAN NSSI、非3GPP的AN NSSI、3GPP管理的RAN NSSI组成,则第二管理实体,分别向适合的第三管理实体发送请求。
502、第二管理实体确定NSSI和/或NF之间的连接关系。
其中,NSSI和/或NF之间通过连接关系能够唯一确定这些NSSI/或NF如何组成一个NSI,该连接关系可以在第二管理实体获取到NST以及第一创建请求后,通过对NSI的结构进行合适的分解得到,例如要组成一个由RAN和CN构成的网络,需要哪些NSSI来组成,这些NSSI之间通过何种拓扑进行连接。能够在第三管理实体完成NSSI的创建后,便按照该方式进行连接构成对应的NSI。
503、第二管理实体根据NST和第一创建请求确定NSI的网络特性参数。
其中,该网络特性参数的种类有多种,例如时延、带宽、丢包率、移动性支持(支持的移动速率,或者高中低移动)等参数,通过这些网络特性参数能够对NSI的功能以及性能进行相应的限定。
504、第二管理实体确定NSSI的需求信息。
其中,该需求可以包括NSSI的描述信息和/或NSSI的网络特性参数;对于第二管理实体从NST中获取NSSI的描述信息,该NSSI的描述信息可以包括以下内容的一项或几项,NSSI的类型、NSST的标识或者NSST全部/部分信息,NSSI的网络特性参数;第二管理实体可以根据这些NSSI的描述信息生成NSSI的需求信息。
该需求信息的生成具体可以包括生成以下几个方面的内容中的一项或多项:
第二管理实体获得NSST的标识,或者NSST的全部/部分信息,NSST的标识或者NSST的全部/部分信息可以直接包含在NST的NSSI描述信息中,该NSSI描述信息可以直接包含于NST中,同时,也可以根据NST所包含的NSSI描述信息,在本地进行计算和选择。
需要说明的是,第二管理实体获得NSSI的网络特性参数具体可以是,第二管理实体在确定了NSI的网络特性参数以及分解后的NSSI之后,对NSSI的网络特性进行确定,此处,由于需要各NSSI的网络特性参数最终能够组合出NSI的网络特性参数,因此需要按照预设的算法和分解策略进行NSSI的网络特性参数的确定,分解策略可以包含在NST中,也可以是在本地预设好。该确定过程需要针对每项参数对NSSI进行分别设置。可以根据分析出的NSSI的网络特性参数来选择合适的NSSI。例如,根据NSSI的能力或者容量或者带宽等参数选择合适的NSSI。又例如,获取每个NSSI的网络特性参数,该网络特性参数例如可以是时延参数,若NSI分解为一个RAN的多个NSSI和一个CN的多个NSSI,则可以将RAN的时延要求为总时延的40%,而CN的时延则要求为总时延的60%。在此情况下,再按照该RAN的时延要求对RAN的各NSSI进行选择,以及按照CN的时延要求对CN的各NSSI进行选择,使得最终的时延达到总时延需求。又例如,NST中直接给出了各个NSSI的网络特性参数,则不需要进行上述分解的过程。
505、第二管理实体向第三管理实体发送第二创建请求。
其中,再通过步骤501至步骤504之中的部分或者全部确定了NSSI、NSSI之间的连接关系,NSST的标识,或NSST的全部/部分信息,以及NSSI的网络特性参数后,第二管理实体便会生成第二创建请求,该第二创建请求中可以将这些NSSI类型、NSSI之间的连接关系,NSST的标识,或NSST的全部/部分信息,以及NSSI的网络特性参数作为NSSI的需求信息,一并发送给第三管理实体。
需要说明的是,该NSSI的需求信息还可以直接包括NSST,使得第三管理实体直接从该需求信息中提取该NSST便可以结合描述信息进行NSSI的创建。当然也可以不包含NSST,而是由第三管理实体根据NSSI的描述在第三管理实体的本地,或者第三管理实体能够获取NSST的渠道获取到这些NSST,并按照NSST和NSSI的描述信息进行NSSI的创建。
需要说明的是,对于NSSI之间的连接关系有两种方式告知给第三管理实体,第一种是NSSI的描述信息中还包含第一NSI包含的NSSI之间的连接关系,第三管理实体在接收到该描述信息后即可获知这些连接关系;第二种是第二管理实体向所述第三管理实体发送第一消息,该第一消息中携带有所述第一NSI包含的NSSI之间的连接关系;该第一消息可以是第二管理实体单独向第三管理实体发送的消息,该第一消息也可以随着需求信息一起发送给第三管理实体。在具有该连接关系的情况下,第三管理实体能够更为顺利的创建第一NSSI。
506、第三管理实体根据第二创建请求确定NSST。
其中,第三管理实体在接收到第二创建请求后,便可根据该第二创建请求中的NSSI的需求信息中直接提取NSST;或者根据NSSI的需求信息,自行选择一个NSST,例如根据NSSI的类型和NSSI的网络特性参数,匹配一个合适的NSST;或者可以从第二创建请求中获取NSSI 的标识,通过该标识从在第三管理实体的本地,或者第三管理实体能够获取NSST的渠道获取到这些NSST。
507、第三管理实体根据NSST和NSSI的描述信息生成NSSI。
其中,第三管理实体在获取到NSST以及从NSSI的描述信息后,便得到足够生成NSSI的信息,对于第三管理实体对于能够支持的NSST,即是可以管理的NSSI对应的NSST,第三管理实体能够根据NSST以及这些NSSI的描述信息生成对应的NSSI,由于之前已经通过第一信息或者直接在需求信息中获取了NSSI的连接关系,生成的NSSI便会按照这些连接关系进行连接,便可完成整个NSI的创建。
实施例3
上面对本申请实施例的网络切片模板的处理方法进行了介绍,下面对本申请实施例中,根据网络切片模板生成的网络切片实例的监控进行说明,请参阅图6,图6是本申请实施例的网络切片模板的处理方法的一个实施例图,该实施例中,包括第一管理实体、第二管理实体和第一设备;该第一管理实体为需求NSI的管理实体;该第二管理实体为管理NSI的管理实体,当然该第二管理实体还支持一些NST,并能够根据支持的NST生成NSI。该第一设备实际上可以是存储设备,该第一设备提供与第二管理实体以及其他需求NSI的实体的连接,其他需求NSI的实体以及第二管理实体均可通过与第一设备的连接访问该第一设备上存储的内容。第二管理实体监控正在运行的NSI的具体过程可以包括:
601、第二管理实体根据已创建的NSI生成第一NSI描述信息和/或第一NSI运行记录。
其中,该NSI是由第二管理实体所管理的NSI,该第二管理实体能够读取到该NSI的各种信息,例如该NSI的网络特性的参数以及生命周期管理参数等,又例如该NSI对应的NST所包含的各种如本申请实施例的NST说明中描述的信息。通过对如生命周期管理参数中的第一动作以及参数的监控,能够对整个NSI的运行情况进行确定,通过NSI对应NST说明中的内容,能够对NSI描述信息进行确定。
602、第二管理实体将该NSI的标识和对应的第一NSI描述信息和/或第一NSI运行记录存储至所述第一设备。
其中,在完成第一NSI描述信息和/或第一NSI运行记录的生成后,第二管理实体会将第一NSI描述信息和/或第一NSI运行记录对应的NSI的标识连同第一NSI描述信息和/或第一NSI运行记录一并存入第一设备,并且该NSI的标识与第一NSI描述信息和/或第一NSI运行记录相关联。从而使得如第一管理实体这类设备能够通过NSI的标识便可读取到该第一NSI描述信息和/或第一NSI运行记录,从而对该NSI的整个生命周期的情况得以了解。
需要说明的是,存入该NSI的标识以及第一NSI描述信息和/或第一NSI运行记录的同时,还可以按照如实施例1中针对第一NST信息的设定来设置鉴权。例如将该第一NSI描述信息和/或第一NSI运行记录设定开放信息,对于不同的NSI,可设定不同的开放信息;当然,还可以将第一管理实体的类型、标识和等级之中的至少一个与开放信息进行绑定,从而使得只有符合该绑定关系的第一设备才能顺利从该第一设备中读取到第一NSI描述信息和/或第一NSI运行记录。
603、第一管理实体向第一设备发送第一读取请求。
其中,该第一读取请求中携带有NSI的标识,第一管理实体在确定了要读取的NSI后,便会确定该NSI的标识,接着向第一设备发送的第一读取请求中便会携带该NSI的标识。
604、第一设备向第一管理实体发送对应NSI的第一NSI描述信息和/或第一NSI运行记录。
其中,第一设备在接收到该第一读取请求后,便根据该第一读取请求中携带的NSI的标识查找对应的第一NSI描述信息和/或第一NSI运行记录,并将该第一NSI描述信息和/或第一NSI运行记录返回给第一管理实体。当然若是该第一NSI描述信息和/或第一NSI运行记录设有鉴权,还需要先确定第一管理实体对应的开放信息,只有开放信息符合的情况下,才会将该第一NSI描述信息和/或第一NSI运行记录返回给第一管理实体。
需要说明的是,对于第一设备内存储某一NSI对应的第一NSI描述信息和/或第一网络切片实例运行记录,第二管理实体还会周期性的对该NSI的运行状态进行检测,并生成该NSI的第二NSI描述信息和/或第二网络切片实例运行记录,并发送至第一设备,从而更新第一设备上的第一NSI描述信息和/或第一NSI运行记录。能够使得第一设备上存储的NSI的NSI描述信息和/或NSI运行记录能够反映该NSI当前的运行状态,以及之前的运行状态。
实施例4,
上面对本申请实施例的已创建的NSI的监控过程进行了说明,下面对本申请实施例的网络切片模板的处理方法的一个实施例进行说明。该实施例中,区别于实施例1,在第一管理实体和第二管理实体中增加第一设备作为中间设备,第二管理实体生成的第一NST信息不再直接发送至第一管理实体,而是发送至第一设备存储,再由第一管理实体从该第一设备中读取该第一NST信息进行第一创建请求的生成。具体的,请参阅图7,图7是本申请实施例的网络切片模板的处理方法的一个实施例图,该方法中,第一管理实体和第二管理实体均连接至第一设备,该方法可包括:
701、第二管理实体生成第一NST信息。
其中,该第一NST信息中可包括该第二管理实体的标识,以及至少一个NST的全部信息的子集,对于一个NST来说,其包含的全部信息可以参见本申请实施例的NST说明的内容。一个NST的全部信息的子集可是该全部信息中的部分信息,也可以是该全部信息,具体的可根据第二管理实体实行的策略的不同而不相同。
此外,与实施例1中步骤302中针对该第一NST信息设定相应的开放信息类似,本实施例中也可以针对第一NST信息生成相应的开放信息。而这些开放信息一方面决定第一NST信息的公开程度,另一方面,该开放信息还可以与第一管理实体的某项参数相对应,只有与开放信息具有对应关系的第一管理实体才可从第一设备中读取到第一管理实体对应的开放信息所对应的第一NST信息。而与开放信息没有对应的第一管理实体无法从第一设备中读取到第一NST信息。
702、第二管理实体将第一NST信息存储第一设备。
其中,第二管理实体在完成第一NST信息的生成后,便会将该第一NST信息存储至第一设备,以及一并关联存入第二管理实体的标识。
703、第一管理实体向第一设备发送第一读取请求。
其中,该第一读取请求中携带有第二管理实体的标识。当然还可以包括有第一管理实体的类型、等级和标识之中的至少一种。
704、第一设备向第一管理实体发送第二管理实体存入的第一NST信息。
其中,第一设备在接收到该第一读取请求后,首先便会从该第一读取请求中获取第二管理实体的标识,接着按照该第二管理实体的标识在第一设备内查找对应该标识的第一NST信息,并将该第一NST信息发送给第一管理实体。
需要说明的是,在给第一管理实体发送第一NST信息之前,还可以对第一管理实体的身份进行验证。该验证方式即获取第一管理实体的类型、等级和标识之中的至少一种,而后将这些信息与第一NST信息所绑定的开放信息进行绑定查找,只有第一管理实体的类型、等级和标识之中的至少一种能够对应到该开放信息,才确定该第一管理实体是合法的,并将该第一NST信息按照该开放信息发送给第一管理实体。
