Description

一种NSI的PNF更新方法、设备和计算机可读存储介质 技术领域
本发明实施例涉及移动通信技术领域,尤其涉及一种网络服务实例(NSI)的物理网络功能(PNF)更新方法、设备和计算机可读存储介质。

相关NFV标准中,对网络服务的实例化主要集中在对网络功能虚拟化基础设施(NFVI)的管理和编排。例如:在一个网络服务(Network Service,NS)实例中,可以通过增加已有VNF实例、实例化新的VNF实例、修改相关VNF配置等操作完成对网络实例的更新。
相关技术中,可以通过运营支撑系统(OSS)/网络管理器(NM)进行网络服务实例化,并根据需要,例如:根据容量需求、带宽需求以及转发路径等对NS实例(NSI)进行更新。NSI的更新,可以采用增加VNF实例、更新VNFFG以及更新VL等手段完成。但是,这些调整均是针对虚拟资源设施或虚拟网元的。而在RAN侧,除了部署在NFVI上的虚拟化网络功能单元外,还有大量的传统物理硬件。同时,RAN侧网络场景对容量调整、覆盖范围调整需求同样非常迫切,例如:通过增加物理硬件扩大区域覆盖、更改物理硬件连接提高区域容量等等。因此,为了提高RAN侧网络调整灵活性,以及对RAN侧网络编排进行针对性增强,亟待一种有效的手段。

表1
入参(输入参数)如下表2所示:

表2
可知,相关技术中,不包含向NS实例中动态增加、修改或删除PNF的功能。为了提高RAN侧的网络调整灵活性,对RAN侧网络编排进行针对性增强,向网络中增加、修改PNF或移除一些PNF是提高RAN侧网络编排的必要手段。
本实施例提出一种在网络服务实例的PNF更新方式,使OSS/NM通过Os-ma-nfvo参考点的NS生命周期管理接口,实现对NSI的PNF资源调整。 通常,PNF的增加、修改和删除,还需要对应调整VNFFG和/或VL以创建或移除PNF与VNF间的转发关系或虚拟链路,该部分为公知技术,此处不再赘述。
本实施例的更新类型、调整方式可如下所述:
在UpdateType中增设:AddPnf、ModPnf、RmPnf等更新类型,具体的:
实施例一
在网络服务实例中增加PNF——AddPnf
Figure PCTCN2018114665-appb-000005
表3
当RAN需要通过增加PNF来增加空口覆盖区域、满足容量需求等场景时,OSS/NM可在Os-ma-nfvo参考点通过UpdateNsRequest消息进行PNF增加,其中UpdateType设置为AddPnf。入参AddPnfInfo携带本次需要加入NSI的PNF信息,如表3所示。
如果需要新增物理网络功能描述符(PNFD),则在更新网络实例前,应在Os-ma-nfvo参考点的NSD管理接口首先携带(Onboard)对应的PNFD。
实施例二
在网络服务实例中修改PNF——ModPnf
Figure PCTCN2018114665-appb-000006

当RAN侧需要修改PNFInfo中的信息时,例如:更改连接点等,OSS/NM 在Os-ma-nfvo参考点通过UpdateNsRequest消息进行PNF信息修改,其中UpdtaeType设置为ModPnf。入参ModPnfInfo携带本次需要修改NSI中的PNF信息,如表4所示。
如果需要更新PNFD,则在更新网络实例前,应在Os-ma-nfvo参考点的NSD管理接口首先更新(Update)对应的PNFD。
实施例三
在网络服务实例中移除PNF——RmPnf
Figure PCTCN2018114665-appb-000007
表5
当RAN侧需要移除PNFInfo中的信息时,OSS/NM在Os-ma-nfvo参考点通过UpdateNsRequest消息进行PNF移除,其中UpdtaeType设置为RmPnf。入参RmPnfInfo携带本次需要移除NSI中的PNF信息,如表5所示。
