本申请实施例的主要目的在于提出一种网络切片方法、装置、电子设备及存储介质,可以将能力开放与网络切片相结合,在网络切片的层面上实现能力开放。
本申请提出的网络切片方法,通过将NEF网元提供的至少部分能力作为供选择的能力开放参数,获取被选择的能力开放参数,根据被选择的能力开放参数形成网络切片,可以使用户根据自身需求选择合适的能力开放参数形成相应的网络切片,从而使能力开放与网络切片相结合,在网络切片的层面上实现能力开放。
本申请第一实施方式涉及一种网络切片方法,通过将NEF网元提供的至少部分能力作为供选择的能力开放参数,获取被选择的能力开放参数,根据被选择的能力开放参数形成网络切片,可以使用户根据自身需求选择合适的能力开放参数形成网络切片,从而将能力开放与网络切片相结合,在网络切片的层面上实现能力开放。
应当说明的是,本申请实施方式提供的网络切片方法的执行主体可以为负责进行网络切片的核心网设备,具体可以是网络切片管理系统的核心网设备。
本申请实施方式提供的网络切片方法的具体流程如图1所示,具体包括以下步骤:
S101:将NEF网元提供的至少部分能力作为供选择的能力开放参数。
其中,网络曝光功能(Network Exposure Function,NEF)网元是5G核心网与外部交互相关能力和信息的接口。请参考图2,其为NEF网元的结构示意图,应用程序APP1、APP2……APPn通过NEF网元与5G核心网的PCF(Policy Control function,策略管控功能)、UDM(Unified Data Management,统一数据管理)等网元进行交互,应用程序与NEF网元之间和NEF与核心网的网元之间的交互具体可以是通过超文本传输协议(http)或安全套接字层超文本传输协议(https)进行交互。
随着5G网络协议的更新,NEF网元提供的能力也会发生变化:在R15规范中,NEF网元面向应用功能(Application Function,AF)提供的能力包括:QoS(服务质量)能力、事件监控、参数配置、设备触发、PFD(报文流描述)管 理、流量引导、背景流量以及策略计费等服务能力;在R16规范中,R16规范一方面对R15规范中定义的开放服务做了补充和增强,同时新增了NIDD(Non-IP Data Delivery)、数据分析、网络状态、MSISDN-less MO消息、IPTV(网络协议电视)配置等能力开放服务。应当说明的是,以上并未将NEF提供的所有能力都列举出来,NEF网元提供的能力可以包括以上列举的能力,也包括实际具备但未列举出来的能力。若随着5G网络协议的更新NEF网元提供的能力有所增加,则NEF网元提供的能力应包括新增加的能力。
在将NEF网元提供的能力作为供选择的能力开放参数时,具体可以是在一个平台上将NEF网元提供的能力作为能力开放参数展示出来供用户进行选择,例如在5G网络的门户网站上展示出来供用户选择,具体展示和选择的形式可以根据实际需要进行设置,此处不做具体限制,只需要将NEF网元提供的至少部分能力作为能力开放参数展示出来,用户可以进行选择即可。其中,用户可以为个人用户也可以为企业用户。实际应用中,可以是核心网设备在接收到网络切片的请求时,向用户展示以NEF网元提供的能力对应的能力开放参数,使用户根据自身需求选择合适的能力开放参数。
可选地,在将NEF网元提供的能力作为供选择的能力开放参数时,可以根据不同的用户提供不同的能力作为能力开放参数。例如,可以将用户划分为不同的类别,不同的类别对应不同的能力开放参数,在用户登录时,根据用户的类别展示相应的能力开放参数供用户进行选择。
由于将NEF网元提供的能力作为能力开放参数展示给用户进行选择时,用户对相应的能力开放参数或对应的NEF网元提供的能力并不熟悉,可以在展示能力开放参数时增加能力开放参数的说明,例如通过超链接的形式增加相应的说明。
S102:获取被选择的能力开放参数。
可选地,在获取被选择的能力开放参数时,可以由用户对相应的能力开放参数全部选择完成后,向核心网设备发送一个构建网络切片的请求,在请求中携带所有被选择的能力开放参数;核心网设备在接收到请求后,从请求中获取所有被选择的能力开放参数。
例如,用户选择了“事件监控”和“流量引导”两个能力开放参数,然后 向核心网设备发送构建网络切片的请求,在发送的请求中携带了“事件监控”和“流量引导”两个被用户选择的能力开放参数,核心网设备在接收到用户的请求后,从请求中获取到被选择的能力开放参数为“事件监控”和“流量引导”两个能力开放参数。
由于NEF网元提供的能力包括很多种,用户在实际选择时,可能并不清楚该选择哪些能力参数,因此可以在展示能力开放参数时增加能力开放参数的推荐。在一个具体的例子中,在S102之前,即在获取被选择的能力开放参数之前,还包括:获取当前用户的信息;获取关联用户选择的能力开放参数作为推荐能力开放参数,其中,关联用户为信息与当前用户的信息相似度达到预设阈值的用户;将至少部分推荐能力开放参数推荐给当前用户。
其中,用户的信息可以是使用场景、使用人数或其它要求等信息。相似度的预设阈值例如可以是70%、80%、90%等,此处不做具体限制。在计算信息的相似度时,可以采用余弦相似度、欧氏距离等方法进行计算。关联用户可以是其它已构建网络切片的用户。
在将至少部分推荐能力开放参数推荐给当前用户时,可以是将关联用户较大概率(大于预设概率阈值)选择的能力开放参数推荐给用户。例如,A用户输入的信息为a,而包括信息a的其它用户80%选择b能力开放参数,则将b能力开放参数作为推荐能力开放参数推荐给A用户。
通过获取当前用户的信息,根据信息相似的用户选择的能力开放参数进行能力开放参数的推荐,可以使当前用户更容易选择到适合自身需求的能力开放参数。
S103:根据被选择的能力开放参数形成网络切片。
在根据被选择的能力开放参数形成网络切片时,可以是调用MANO(网络编排模块)编排被选择的能力开放参数形成网络切片,使形成的网络切片具备与被选择的能力开放参数对应的能力(NEF网元提供的能力)。
在调用MANO编排网络切片时,可以是将多个网络切片进行统一编排,从而使网络切片的资源得到更加合理的分配。请参考图3,其为本申请实施方式提供的网络切片方法在调用MANO编排能力开放参数的示意图,图中的NFs(Network Functions,网络功能)即对应能力开放参数,调用MANO编排能力 开放参数形成网络切片时,对多个网络切片(网络切片1、网络切片2……)和多个能力开放参数(NFs1、NFs2、NFs3……)统一进行编排,最终形成具备相应能力的网络切片。
在一个具体的例子中,在S103之后,即在根据被选择的能力开放参数形成网络切片之后,还包括:
在网络切片中获取应用层的能力开放需求,根据能力开放需求形成应用层的应用程序接口。
即在网络切片形成后,进一步根据用户在应用层的能力开放需求形成相应的应用程序接口供用户进行使用,从而使应用层面的能力开放与网络切片的层面上的能力开放相结合,进一步满足不同用户和不同应用场景的多样需求。
本申请实施方式提供的网络切片方法,通过将NEF网元提供的至少部分能力作为供选择的能力开放参数,获取被选择的能力开放参数,根据被选择的能力开放参数形成网络切片,可以使用户根据自身需求选择合适的能力开放参数形成相应的网络切片,从而使能力开放与网络切片相结合,在网络切片的层面上实现能力开放。
本申请第二实施方式涉及一种网络切片方法,第二实施方式与第一实施方式大致相同,主要区别在于:在本申请实施方式中,在根据被选择的能力开放参数形成网络切片之前,还包括:获取网络切片的服务等级协议的需求;而根据被选择的能力开放参数形成网络切片,则包括:根据服务等级协议的需求和被选择的能力开放参数形成网络切片。
本申请实施方式提供的网络切片方法的具体流程如图4所示,包括以下步骤:
S201:将NEF网元提供的至少部分能力作为供选择的能力开放参数。
S202:获取被选择的能力开放参数。
其中,S201-S202与第一实施方式中的S101-S102相同,具体可以参见第一实施方式中的相关描述,为了避免重复,这里不再赘述。
S203:获取网络切片的服务等级协议的需求。
其中,服务等级协议(service-level agreement,SLA)的需求可以包括用户 数的需求、Qos的需求和/或带宽的需求等需求。
可选地,在获取网络切片的服务等级协议的需求时,可以在获取被选择的能力开放参数同时进行获取,例如在用户发送构建网络切片的请求中同时包含有被选择的能力开放参数和服务等级协议的需求,从而使核心网设备在请求中同时获取到这两个信息。
S204:根据服务等级协议的需求和被选择的能力开放参数形成网络切片。
在一个具体的例子中,形成的网络切片为网络切片中的子切片,即网络子切片,根据服务等级协议的需求和被选择的能力开放参数形成网络切片,如图5所示,包括以下步骤:
S2041:利用CSMF将服务等级协议的需求和被选择的能力开放参数转化为网络切片需求。
S2042:利用NSMF根据网络切片需求创建网络切片实例,并在网络切片实例中选择与服务等级协议的需求相适应的网络子切片。
S2043:利用NSSMF完成网络子切片的资源申请。
S2044:利用MANO完成网络子切片的管理编排,并利用EMS完成网络子切片的参数配置。
对于S2041-S2042,详细说明如下:
网络切片由网络切片管理系统创建和管理,一个网络切片管理系统可以创建多个网络切片,并同时对它们进行管理,例如对网络切片在运行过程中的网络性能进行监视、故障管理、修改配置参数等。网络切片管理系统可以包括:通信服务管理功能(communication service management function,CSMF)、网络切片管理功能(network slice management function,NSMF)和网络子切片网管理功能(network slice subnet management function,NSSMF)。其中,CSMF主要用于将运营商和/或第三方客户的通信服务相关需求转化为网络切片的参数信息等;NSMF主要用于对网络切片的生命周期、性能、故障等进行管理等;NSSMF主要用于对网络切片子网的生命周期、性能、故障等进行管理。网元管理系统(Element Management System,EMS)主要完成国际电信联盟电信管理网(ITU TMN)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。
以下以一个具体的例子来说明以上过程,请参考图6,其为本申请实施方 式提供的网络切片的流程示例图。具体的流程可以为:
1、用户通过门户网站订购网络切片的通信服务,在订购时,根据自身需求选择合适的服务等级协议和能力开放参数,然后向CSMF提交申请相应的通信服务的请求,在请求中携带有服务等级协议的需求和被用户选择的能力开放参数;
2、核心网设备(网络切片管理系统)利用CSMF从请求中获取相应的服务等级协议的需求和被用户选择的能力开放参数;
3、利用NSMF根据网络切片需求创建网络切片实例,并从网络切片实例中选择与用户对应的服务等级协议的需求相适应的网络子切片;
4、利用NSSMF完成网络子切片的资源申请,并对网络子切片进行生命周期管理等;
5、调用MANO完成网络子切片的管理编排,并利用EMS完成网络子切片的参数,完成用户需求的网络子切片的构建;
6、将网络子切片部署完成的结果通知用户可以使用相应的通信服务。
本申请实施方式提供的网络切片方法,除了获取被选择的能力开放参数之外,还获取网络切片的服务等级协议的需求,根据服务等级协议的需求和被选择的能力开放参数形成网络切片,可以将被选择的能力开放参数与服务等级协议的需求结合起来形成网络切片,使网络切片在具备能力开放的能力的同时也满足用户对于服务等级协议的需求。
此外,本领域技术人员可以理解,上面各种方法的步骤划分,只是为了描述清楚,实现时可以合并为一个步骤或者对某些步骤进行拆分,分解为多个步骤,只要包括相同的逻辑关系,都在本专利的保护范围内;对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计,但不改变其算法和流程的核心设计都在该专利的保护范围内。
