Description

网络功能自动化管理协调方法、设备和存储介质
本申请要求在2022年01月07日提交中国专利局、申请号为202210015243.7的中国专利申请的优先权，以上申请的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，例如涉及一种网络功能自动化管理协调方法、设备和存储介质。
背景技术
在第五代移动通信(5th Generation，5G)阶段，一个比较重要的网络功能管理需求，就是5G网络管理的自动化。目前提出的自动化管理相关技术包括自组织网络(Self-Orgnized Network，SON)、意图驱动网络等。在5G网络中，还会引入人工智能(Artificial Intelligence，AI)技术及大数据技术，基于这些技术，5G网络将具有智能分析及决策能力，如果这些智能分析及决策的结果能够被自动执行，则可以基本实现5G网络的自动化管理。
当系统中有多个自动化管理功能(例如不同的SON功能、不同目的的管理数据分析功能(Management Data Analytic Function，MDAF)等)在不同层次(例如切片层、切片子网层、网络功能层等)执行时，会产生不同的自动化操作指令。当同时有两个或多个自动化操作指令作用于同一切片、子切片或网络功能时，由于这些指令是处于不同的目的，就有可能产生冲突。如何对存在冲突的自动化功能进行协调，是目前亟待解决的问题。
发明内容
本申请提供一种网络功能自动化管理协调方法、设备和存储介质，解决了网络功能自动化管理时存在冲突的问题。
第一方面，本申请实施例提供了一种网络功能自动化管理协调方法，包括：
当接收到对网络功能的第一自动化管理指令时，对第一自动化管理指令和缓存的自动化管理指令进行冲突检测；
若第一自动化管理指令与缓存的自动化管理指令存在冲突，则对第一自动化管理指令和缓存的自动化管理指令进行协调处理，并将协调结果作为协调后的自动化管理指令缓存；
从缓存中读取协调后的自动化管理指令并执行。
第二方面，本申请实施例提供了一种网络设备，包括：
一个或多个处理器；
存储装置，设置为存储一个或多个程序；

第三方面，本申请实施例提供了一种计算机可读存储介质，存储有计算机可执行指令，计算机可执行指令用于第一方面任一种可能的实现方式的网络功能自动化管理协调方法。
附图说明
图1为本申请实施例提供的一种网络功能自动化管理协调方法的流程图；
图2为本申请实施例提供的一种网络功能自动化管理协调装置的结构示意图；
图3为一实施例提供的一种网络设备的结构示意图。
具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。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任意组合。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在本申请实施例中，“可选地”或者“示例性地”等词用于表示作例子、例证或说明。本申请实施例中被描述为“可选地”或者“示例性地”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“可选地”或者“示例性地”等词旨在以具体方式呈现相关概念。
图1为本申请实施例提供的一种网络功能自动化管理协调方法的流程图，如图1所示，本实施例提供的网络功能自动化管理协调方法包括：
步骤S110，当接收到对网络功能的第一自动化管理指令时，对第一自动化管理指令和缓存的自动化管理指令进行冲突检测。
本实施例提供的网络功能自动化管理协调方法，应用于具有网络功能自动化管理能力的网络中，由网络中的自动化管理功能、节点或设备执行。网络中的各种网络功能可能被两个或两个以上的自动化操作指令共同指示进行操作， 但由于不同的自动化操作指令可能是由不同的网元或功能处于不同目的产生的，因此对于同一网络功能的多个不同的自动化操作指令之间可能存在冲突。例如一个自动化操作指令需要使网络功能的A参数提高，而另一个自动化操作指令则需要使网络功能的A参数降低，在这种情况下如何执行这两个自动化操作指令，使得网络功能能够正常运行，就是提高网络功能自动化管理能力的重要因素。
本实施例提供的网络功能自动化管理协调方法，就是用于对同一个网络功能的多个不同自动化管理指令进行协调处理。其中网络功能是指网络中实现一种或多种功能的功能模块、网络节点或设备，一个网络功能也可以是网络中的一个切片或一个子切片，在本申请实施例中均以网络功能为例进行说明。在接收到对网络功能的第一自动化管理指令时，为了避免与其他自动化管理指令的执行发生冲突，先不执行第一自动化管理指令，而是对第一自动化管理指令和缓存的自动化管理指令进行冲突检测。其中，缓存的自动化管理指令是在接收第一自动化管理指令之前接收到的且未被执行的自动化管理指令。若在接收到第一自动化管理指令时，并未缓存其他自动化管理指令，则直接缓存第一自动化管理指令。对第一自动化管理指令和缓存的自动化管理指令进行冲突检测，就是判断第一自动化管理指令和缓存的自动化管理指令之间的执行是否存在冲突，例如是否对同一参数进行了调整、是否对不同参数进行调整但调整结果会产生相互影响等。对自动化管理指令之间进行的冲突检测原则，可以是预设的原则，例如预设某些参数的调整会产生相互影响，也可以是模拟各自动化管理指令的执行后根据模拟结果确定是否会产生相互影响。总之，若第一自动化管理指令和缓存的自动化管理指令均被执行会对网络功能的正常运行产生影响，就意味着第一自动化管理指令和缓存的自动化管理指令存在冲突。
步骤S120，若第一自动化管理指令与缓存的自动化管理指令存在冲突，则对第一自动化管理指令和缓存的自动化管理指令进行协调处理，并将协调结果作为协调后的自动化管理指令缓存。
若第一自动化管理指令与缓存的自动化管理指令不存在冲突，则可以直接将第一自动化管理指令进行缓存，无需对第一自动化管理指令和缓存的自动化管理指令进行处理，但此时第一自动化管理指令和缓存的自动化管理指令可能并不被执行，这是由于同一时间并发的自动化管理指令可能存在多个，因此需要分别对其进行冲突检测后，确定各自动化管理指令之间均不存在冲突后方可执行。
而若第一自动化管理指令与缓存的自动化管理指令存在冲突，则需要对第一自动化管理指令和缓存的自动化管理指令进行协调处理，然后将协调结果作为协调后的自动化管理指令缓存。对第一自动化管理指令和缓存的自动化管理指令进行协调处理，就是确定对该网络功能执行何种指令。其中，对第一自动化管理指令和缓存的自动化管理指令进行协调处理，可以包括如下几种方式：1、修改或删除缓存的自动化管理指令，2、修改或废弃第一自动化管理指令，3、合并第一自动化管理指令和缓存的自动化管理指令，4、根据第一自动化管理指令和缓存的自动化管理指令生成新的自动化管理指令。采用那种方式进行处理，需要根据不同的指令执行结果确定。当修改或删除缓存的自动化管理指令时，将第一自动化管理指令作为协调后的自动化管理指令缓存。当修改或废弃第一自动化管理指令时，将缓存的自动化管理指令作为协调后的自动化管理指令缓存。当合并第一自动化管理指令和缓存的自动化管理指令时，合并第一自动化管理指令和缓存的自动化管理指令，并将合并的自动化管理指令作为协调后的自动化管理指令缓存。当根据第一自动化管理指令和缓存的自动化管理指令生成新的自动化管理指令时，根据第一自动化管理指令和缓存的自动化管理指令生成新的自动化管理指令，并将新的自动化管理指令作为协调后的自动化管理指令缓存。
步骤S130，从缓存中读取协调后的自动化管理指令并执行。
为了避免自动化管理指令之间的冲突，网络功能并不直接执行接收到的自动化管理指令，而是从缓存中读取协调后的自动化管理指令执行。由于缓存的协调后的自动化管理指令是考虑了自动化管理指令之间的冲突，在进行冲突协调后得到的，因此执行协调后的自动化管理指令，不会对网络功能的正常运行产生影响，从而解决了并发的自动化管理指令对同一网络功能产生的冲突，提高了网络功能自动化管理的能力。
网络功能的自动化管理指令是持续接收的，不同的自动化管理指令具有一定的时效，因此只有在一定时间内的自动化管理指令之间才会出现冲突。因此，缓存的自动化管理指令可以具有一个缓存时间属性，当缓存时间到时，再执行自动化管理指令的相应操作，这样可以进一步地避免自动化管理指令之间的冲突。
本实施例提供的网络功能自动化管理协调方法，当接收到对网络功能的第一自动化管理指令时，对第一自动化管理指令和缓存的自动化管理指令进行冲突检测，若第一自动化管理指令与缓存的自动化管理指令存在冲突，则对第一 自动化管理指令和缓存的自动化管理指令进行协调处理，并将协调结果作为协调后的自动化管理指令缓存，最后从缓存中读取协调后的自动化管理指令并执行，由于缓存的协调后的自动化管理指令是考虑了自动化管理指令之间的冲突，在进行冲突协调后得到的，因此执行协调后的自动化管理指令，不会对网络功能的正常运行产生影响，从而解决了并发的自动化管理指令对同一网络功能产生的冲突，提高了网络功能自动化管理的能力。
在一实施例中，为了使网络功能具有缓存自动化管理指令的能力，可以为网络功能配置操作指令缓存管理对象类，操作指令缓存管理对象类的实例被网络功能的管理对象类的实例所包含，操作指令缓存管理对象类的实例用于缓存自动化管理指令。
其中，操作指令缓存管理对象类包括缓存时间窗长度和操作指令列表，缓存时间窗长度用于指示缓存管理对象类的实例中操作指令被缓存时间，操作指令列表用于存储缓存的操作指令的内容。缓存时间窗长度的单位可以为毫秒。另外，操作指令列表还可以用于存储操作指令的内容和缓存时间；当操作指令列表中存储有操作指令对应的缓存时间则忽略缓存时间窗长度，也就是说，操作指令列表中也可以包括缓存时间属性，这里的缓存时间属性用于规定该操作指令可以被缓存的时间，当该缓存时间属性值存在时，使用该时间作为该操作指令的缓存时间，否则使用上述缓存时间窗长度作为该操作指令的缓存时间。缓存时间窗长度和缓存时间用于当缓存中存储的协调后的自动化管理指令的缓存时间到时，则执行缓存协调后的自动化管理指令。
在一实施例中，为了使网络功能具有自动化管理指令的协调能力，可以为网络功能配置操作指令冲突协调服务，该操作指令冲突协调服务用于对接收的操作指令进行冲突检测并进行协调；协调结果存入操作指令对应的管理对象实例所包含的操作指令缓存实例。当接收到对网络功能的第一自动化管理指令时，判断网络功能的操作指令冲突协调服务是否开启，若开启则对第一自动化管理指令和缓存的自动化管理指令进行冲突检测。
