本公开有益效果如下:
本公开实施例提供的技术方案中,由于根据网络切片需求的修改来决定执行相应的网络管理操作,因此提供了针对增加因服务等级协议(Service Level Agreement,SLA)修改或更新触发的网络管理或运维流程的技术方案。
进一步的,提供了用户需求修改触发的网络管理在网络切片修改、网络切片重新分配以及上下线管理方面的处理技术方案,整合了原有的修改、分配等流程。
附图说明
此处所说明的附图用来提供对本公开的进一步理解,构成本公开的一部分,本公开的示意性实施例及其说明用于解释本公开,并不构成对本公开的不当限定。在附图中:
图1为本公开实施例中网络切片的处理方法实施流程示意图之一;
图2为本公开实施例中网络切片的处理方法实施流程示意图之二;
图3为本公开实施例中网络切片需求修改处理实施流程示意图;
图4为本公开实施例中网元结构示意图之一;
图5为本公开实施例中网元结构示意图之二。
具体实施方式
发明人在发明过程中注意到:
当前已有的技术方案中对于网络切片实例(Network Slice Instance,NSI)的修改仅仅涉及执行方法,并未讨论具体的由于用户需求修改触发的网络切片流程。
且用户需求修改触发的网络管理不仅仅涉及网络切片修改,还有可能存在网络切片重新分配以及上下线管理,故当前已有的技术方案状况为缺失。
基于此,本公开实施例中提供了针对增加因服务等级协议(Service Level Agreement,SLA)修改或更新触发的网络管理或运维流程的技术方案,下面结合附图对本公开的具体实施方式进行说明。
在说明过程中,将分别从多个网元侧的实施进行说明,然后还将给出它们配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着它们必须配合实施、或者必须单独实施,实际上,当它们分开实施时,其也各自解决自身一侧的问题,而它们结合使用时,会获得更好的技术效果。

步骤101、第一网元接收第一消息,所述第一消息用于指示网络切片需求的修改;
步骤102、第一网元决定执行相应的网络管理操作。
具体的,第一网元可以为服务提供者,或网络管理功能(network fuction management fuction,NFFMF),或子网络切片管理功能(network slice subnet management fuction,NSSMF),或网络切片管理功能(network slice management fuction,NSMF)。
实施中,决定执行相应的网络管理操作,包括:
网络切片修改;和/或,网络切片分配。

实施中,所述第一消息为以下内容之一或者其组合:
网络容量、网络拓扑、网络配置、网络性能参数、业务需求。
具体的,第一消息可能就是用户提的一个改变的需求,比如说增加了一个用户面功能(User Plane Function,UPF)。服务提供者(Provider)也即第一网元,会把第一消息中的需求映射到服务概况(service profile)内,也即生成了新的service profile。service profile内有很多参数,第一网元根据新的service profile中的各个参数,来判断当前为该用户提供服务的切片是否能够满足需求。举个例子,比如新的service profile中带宽一项为12G,当前为该用户提供服务的切片带宽设置为10G但UPF的能力可以到达12G,那就直接修改该切片就可以,修改该切片的结果就体现为网络容量的扩充。网络容量、网络拓扑、网络配置、网络性能参数、业务需求是经过判断后修改/新分配切片后的实现的一个结果。
实施中,所述第一消息为包含通用切片模板(Generic Slice Template,GST)的网络切片相关需求。
实施中,还可以包括:
在接收到所述第一消息后,从所述网络切片相关需求得到新的服务描述文件(service profile);

具体的,用户发起网络切片需求修改的请求:其修改可以是对于网络容量、网络拓扑、网络配置等相关的修改要求,网络相关性能参数或业务需求等的修改;此外,对应修改也可以体现在用户的网络切片需求模板通用切片模板(Generic Slice Template,GST)中。
实施中,当网络切片需求修改请求导致最终的网络拓扑或者最终的网络部署变化时,触发网络切片分配。
具体的,如果修改需求影响了最终的网络拓扑或者网络部署等方面,则需要为修改后的网络切片需求重新分配网络切片。
实施中,网络切片修改,包括:
将修改的需求对应到相应的ServiceProfile参数后进行修改,或者基于新的网络切片需求生成新的serviceprofile参数后进行修改;
基于相关参数进行需求分解,并体现至对整个NSI网络切片实例和NSSI子网络切片实例的修改中。
具体的,对于网络相关性能参数或业务需求等的修改(例如最大接入用户数等),第一网元(如NSMS_Provider)将修改的需求首先对应到相应的ServiceProfile(服务配置文件)参数修改,然后基于相关参数进行需求分解并体现至对于整个NSI网络切片实例和网络切片子网实例(Network SliceSubnet Instance,NSSI)子网络切片实例的修改中。
实施中,网络切片修改,包括:
第一网元确定需修改的网络切片参数请求,所述参数请求是通过第二网元发送的网络切片需求修改请求ModifyNsi中携带的NSI的管理标识符和新的网络切片要求确定的;

具体实施中,进一步包括:

实施中,在现有的网络切片实例未向其他网络服务提供贡献时,终止现有网络切片实例后,新建网络切片实例。
具体的,如果修改现有网络切片实例可以满足新的网络切片需求,修改现有的网络切片实例;

实施中,重用现有网络切片或新建网络切片后,进一步包括:
第一网元在重用现有网络切片或新建网络切片成功时将成功的结果或网络切片实例NSI的管理标识通知用户;或,第一网元在重用现有网络切片或新建网络切片失败时将的失败的结果通知用户。
具体的,可以通过一个响应(response),告知用户修改流程完成。在所有流程完成后,可以告知网络切片实例的信息,例如网络切片实例NSI的管理标识。
具体的,触发网络切片实例解分配和分配流程。在网络切片分配流程中,存在使用现有网络切片和重新实例化一个新的网络切片两种选择。
若需要触发解分配和分配流程,在判断是否重用现有网络切片或新建网 络切片的流程中,需要根据修改需求进行分解,例如,若用户接受网络共享且当前网络已有网络切片可以为其服务,则选择重用,原有切片的ServiceProfile不变;若用户不接受网络共享或网络切片需求修改涉及网络拓扑的巨大改变,则需要执行网络切片新建流程,构建新的ServiceProfile。

第一网元将NSI分配结果发送给第二网元。
具体实施中,还可以进一步包括:
如果修改现有NSI或成功创建新NSI,第一网元发送到第二网元的修改结果包括相关网络切片实例信息。
下面结合实例进行说明,其中,各网元对应的具体实施网元分别如下:
第一网元:网络切片管理服务提供者(Network Slice Management Service Provider,NSMS_P);
第二网元:网络切片管理服务消费者(Network Slice Management Service Consumer,NSMS_C);
第三网元:网络切片子网管理服务消费者(Network Slice Subnet Management Service Consumer,NSSMS_C);
第四网元:网络功能实体管理服务提供者(Network Function Management Service Provider,NFMS_P)。
图3为网络切片需求修改处理实施流程示意图,如图3所示,可以包括:
1、用户发起需求修改请求。
用户发起网络切片需求修改的请求:其修改可以是对于网络容量、网络拓扑、网络配置等相关的修改要求。此外,对应修改也可以体现在用户的网络切片需求模板GST中。
2、分析/翻译用户请求,判断网络解决方案,选择1:触发网络切片修改流程,选择2:触发网络切片解分配和分配流程。
NSMS_Provider分析或翻译网络切片需求修改请求,判断并触发相关网络流程。如果修改需求仅仅影响网络相关容量或网络配置,则网络切片修改即可满足;如果修改需求影响了最终的网络拓扑或者网络部署等方面,则需要为修改后的网络切片需求重新分配网络切片。
3a、方案1:触发修改网络切片(NSI)修改流程;
更新Service Profile,修改网络切片(NSI)流程。
如果是方案1,触发网络切片实例修改流程:
对于网络相关性能参数或业务需求等的修改(例如最大接入用户数等),NSMS_Provider将修改的需求首先对应到相应的ServiceProfile参数修改,然后基于相关参数进行需求分解,并体现至对于整个NSI网络切片实例和NSSI子网络切片实例的修改中;
内部流程可以如下:
a)网络切片管理服务提供者(NSMS_P)收到来自网络切片管理服务消费者(NSMS_C)的ModifyNsi(修改NSI)请求,其中包含NSI的管理标识符和新的网络切片相关要求。
b)基于新的网络切片相关需求,NSMS_P调用可行性检查程序。如果可以满足修改要求,转步骤c),否则转步骤e)。
c)SMS_P将NSI修改请求分解为NSSI修改请求,即根据需要为每个NSSI生成新的网络切片子网相关需求。
d)NSMS_P,作为网络切片子网管理服务消费者(NSSMS_C)的角色,调用NSSI修改过程。
e)NSMS_P将NSI修改结果发送到NSMS_C。
3b、触发网络切片解分配和分配流程。
网络切片(NSI)解分配流程;
网络切片(NSI)分配流程,新建或重用Service Profile。
如果是方案2,触发网络切片实例解分配和分配流程。在网络切片分配流程中,存在使用现有网络切片和重新实例化一个新的网络切片两种选择。
若需要触发解分配和分配流程,在判断是否重用现有网络切片或新建网络切片的流程中,需要根据修改需求进行分解,例如,若用户接受网络共享且当前网络已有网络切片可以为其服务,则选择重用,原有切片的ServiceProfile不变;若用户不接受网络共享或网络切片需求修改涉及网络拓扑的巨大改变,则需要执行网络切片新建流程,构建新的ServiceProfile。
内部流程可以如下:
a)网络切片管理服务提供者(NSMS_Provider)收到来自网络切片管理服务消费者(NSMS_Consumer)的分配NSI(AllocateNsi)请求,具有网络切片相关需求。
b)NSMS_Provider根据网络切片相关需求和对现有部署网络切片能力的了解,将提供的需求与所有候选网络切片(NetworkSlice)实例进行比较/匹配,然后决定是使用现有的NSI还是创建一个新的NSI。如果网络切片相关要求允许所请求的NSI被共享,并且如果现有合适的NSI可以重用,则NSMS_Provider可以决定使用现有的NSI。
c)如果使用现有NSI并且需要修改现有NSI以满足网络切片相关要求,则NSMS_Provider调用程序来修改现有NSI。
d)如果创建新的NSI,NSMS_Provider从接收到的网络切片相关需求中推导出网络切片子网相关需求。在NSMS_Provider导出网络切片子网相关要求之前,NSMS_Provider可以调用相应的网络切片子网能力信息查询程序。
e)NSMS_Provider调用NSSI分配过程。
f)NSMS_Provider为NSI创建管理对象实例(Manage Object Instance,MOI),并为NSSI配置MOI的数据网络(Data Network,DN),也可以为创建的MOI配置其他配置信息(体现在具体的网络资源管理(Network Resource Management,NRM)中)。
g)NSMS_Provider将NSI分配结果发送给NSMS_Consumer。如果修改 现有NSI或成功创建新NSI以满足网络切片相关要求,则结果包括相关网络切片实例信息。
