Description

通知消息的处理方法、装置和计算机存储介质
本申请基于申请号为201610942757.1、申请日为2016年11月01日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域，尤其涉及一种通知消息的处理方法、装置和计算机存储介质。
背景技术
在无线通讯系统的管理领域，网络管理系统(Network Management System–NMS)与网元管理系统(Element Management System–EMS)之间的接口称为北向接口(Itf-N)。EMS主要完成ITU(International Telecommunication Union–国际电信联盟)TMN(Telecommunications Management Network-电信管理网络)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，通常不同设备供应商之间的EMS无法通用。NMS主要完成ITU TMN中的网络管理层(NML)功能，负责一个被管网络内所有网元的管理。对于被管网络(称为子网)内存在多个设备供应商的情况，可以通过各自的EMS管理达到管理整个子网的目的。
相关技术中，为了提高通讯网络的灵活性，降低管理成本，由运营商发起提出了网络功能虚拟化(Network Functions Virtualization-NFV)概念，在使用NFV技术的情况下，原来的物理网元设备由虚拟化网络功能(Virtualized Network Function-VNF)代替，使得网络功能与具体硬件解耦，图1是本发明相关技术中的网络功能虚拟化参考架构图，如图1，VNF与底层的网络功能虚拟化基础架构(Network Functions Virtualization  Infrastructure-NFVI)隔离。对于VNF的管理，通过EMS对VNF实例进行现有的维护管理功能，而VNF的生命周期管理功能则通过VNF管理器VNFM完成。底层的虚拟基础架构由虚拟基础架构管理器(VIM)进行管理。而具体的网络业务，则一般通过一个或多个VNF实例来完成。对网络业务的管理，则通过NFV编排器NFVO来进行。实现网络功能虚拟化后，从应用层面来看，要建立一个网络业务实例时，需要先生成网络业务需要的VNF的实例，再由一个或多个VNF实例组成一个网络业务实例，通过网络业务实例来提供网络业务。
现有的网络管理结构一般为包含网络管理系统(Network Management System，NMS)/运营支撑系统(Operations support system，OSS)、EMS和网络设备的三层管理结构；其中，NMS和EMS之间的接口是北向接口，EMS和网络设备之间的接口是南向接口。网络管理系统在北向接口上将每类网络设备模型化为一个管理信息对象类，每个网络设备都会有一个所属对象类的信息对象实例，用标识(Distinguish Name，DN)来表示，信息对象实例中包含所属网络设备的配置信息；管理系统通过对信息对象实例的创建、删除和更新操作来完成对网络设备配置信息的管理，网络设备作为管理实体不会动态变化。
在网络设备虚拟化后，网络功能是在VNF上实现的，网络功能的配置信息也仅在VNF的生命周期内有效。VNF的生命周期管理包括：VNF实例化(Instantiate VNF)、VNF实例结束(Terminate VNF)、VNF实例调整(Scale VNF)和VNF实例更新等。
VNF实例化完成后，会产生VNF实例化完成通知消息，在不同功能网元之间转发，但是随着实例化的增加，这种VNF实例化通知消息很多，导致不同功能网元之间的交互信息的数据量大，接口的转发负荷重及接口拥堵等问题。
发明内容
本发明实施例提供了一种通知消息的处理方法及装置，期望解决VNF实例化通知消息导致的功能网元之间的交互的数据量大、接口负荷重等问题的至少其中之一。

第五方面，本发明实施例提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行前述任意一个技术方案提供的通知消息的处理方法。
在本发明实施例中，网元管理系统EMS接收网络功能虚拟化管理器VNFM发送的VNF实例化完成通知消息，其中，VNF实例化完成通知消息是VNF实例在实例化完成后生成的，EMS根据VNF实例化完成通知消息确定转发VNF实例化完成通知消息，解决了相关技术中对EMS收到的VNF实例化完成通知消息不进行筛选就转发而造成系统负担过大的问题，通过提出一种对EMS收到的VNF实例化完成通知消息进行筛选的方法，为解决EMS不加筛选将所有收到的VNF实例化完成通知消息都转发给NMS的情况下，会给北向接口和NMS造成比较大的不必要的负担的问题提供一种解决方案。
附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1是本发明相关技术中的网络功能虚拟化参考架构图；
图2是根据本发明实施例的通知消息的处理方法流程图；
图3是根据本发明实施例的通知消息的处理装置的结构框图；
图4是本发明实施例的一种VNF实例化完成消息处理方法的流程图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语 “第一”、“第二”等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。
研究VNFM会给EM发送VNF实例化完成通知消息，EM收到VNF实例化完成通知消息后，会不加选择需要将该消息转发需要接收该消息的其他网元，例如，NMS，以使NMS触发实例化与所述VNF实例对应的管理对象实例的操作。
但实际上EMS收到的VNF实例化完成通知消息，有些VNF并不是归所述EM管理的，所以这些消息由所述EMS上报给NMS是多余的。有时候不同的EMS都是接收到同一个VNF实例化完成通知消息，多个EMS接收到之后都会上报给NMS，这样的话，就导致了NMS重复接收同一个VNF实例化完成通知消息。这样的话，由于消息的不加筛选的转发，导致很多重复和不必要的转发，从而导致不同网元之间的交互的消息多，数据量大，导致传输接口的负荷重等各种问题。有鉴于此，在本实施中若网元接收到一个VNF实例化完成通知消息不会不加筛选的直接转发，而是会有选择性的转发符合转发条件的VNF实例化完成通知消息。这里的转发条件为接收到该VNF实例化完成通知消息的网元特定的转发条件，这样就可以避免不需要由该网元转发的VNF实例化完成通知消息的滥发，从而减少重复和冗余转发，从而解决上述问题。在本实施例中，所述网元可为EMS，也可以是VNFM。

实施例4：
本发明实施例还提供一种通知消息的处理方法，包括：
接收网络功能虚拟化管理器VNFM发送的VNF实例化完成通知消息；
当所述VNF实例化完成通知消息满足转发条件时，转发所述VNF实例化完成通知消息。
本实施例提供的通知消息可包括：所述VNF实例化完成通知消息，执行该方法的网元可为如图1中所示的各种网元，例如，VNFM或EMS等。
在本实施例中接收到VNF示例化完成通知消息的网元，在接收到该通知消息之后不会直接转发，而是选择满足转发条件的VNF实例化完成通知消息转发，避免不必要的转发和重复发送等。
例如，VNFM接收到或获取到所述VNF实例化完成通知消息之后，并非是由自己触发的或控制的VNF实例对应的VNF实例化完成通知信息，则不会转发给EMS，若是则会转发给对应的EMS系统。
可选地，所述方法还包括：
根据所述VNF实例化完成通知消息，获取转发条件的判断参数；
根据所述判断参数，确定所述VNF实例化完成通知消息是否满足所述转发条件。
所述VNF实例化完成通知消息中，可携带有VNF实例的标识信息，还可携带有触发VNF实例的请求或指令的消息指示等信息。故在本实施例中，可以直接从所述VNF实例化完成通知信息中提取判断参数，也可以根据所述VNF实例化完成通知消息与其他消息的对应关系，获得所述判断参数。总之，获得所述判断参数的方式有很多种，不限于上述任意一种。
在一些实施例中，所述根据所述VNF实例化完成通知消息，获取转发条件的判断参数，包括：
获取所述VNF实例化完成通知消息指示的VNF实例的标识信息；
所述根据所述判断参数，确定所述VNF实例化完成通知消息是否满足所述转发条件，包括：
根据所述VNF实例的标识信息，确定所述VNF实例是否由当前网元管理系统EMS管理；
当所述VNF实例是由当前网元管理时，确定所述VNF实例化完成通知消息满足所述转发条件。
在另一些实施例中，所述根据所述VNF实例化完成通知消息，获取转发条件的判断参数，包括：
获取所述根据所述VNF实例化完成通知消息对应的VNF实例化命令或请求；
所述根据所述判断参数，确定所述VNF实例化完成通知消息是否满足所述转发条件，包括：
确定所述VNF实例化命令或请求的下发网元；
当所述下发网元为当前网元时，确定所述VNF实例化完成通知消息满足所述转发条件。
可选地，所述当所述VNF实例是由当前网元管理时，确定所述VNF实例化完成通知消息满足所述转发条件，还包括：
确定接收所述VNF实例化完成通知消息的接收网元；
将所述VNF实例化完成通知消息，转发给确定的接收网元。
在图1所示的框架中，可能存在多个EMS系统、多个NMS或VNFM等网元，这些网元之间的连接关系和/或归属关系是不同的。故为了避免消息的滥发和重复发送，在本实施例中，若一个VNF实例化完成通知消息满足转发条件时，且仅是转发给特定的接收网元。例如，通过特定的接口转发给确定的接收网元，或者，重新封装所述VNF实例化完成通知消息，通过重新封装的封装体中携带接收网元的标识，从而有针对性的转发，从而减少滥发和重复发送。
