具体实施方式
下面将参考附图更全面地描述示例实施方式。
需要说明的是，示例实施方式能够以多种形式实施，不应被理解为限于在此阐述的范例。
发明人发现，当前3GPP标准中尚未定义专门的NRF failure流程。若参考3GPP在TS 23.527中定义了服务化架构下NF failure的检测方法，则NRF failure的检测和通知还需要借助备用NRF，而备用NRF在刚确认原NRF failure的时候，尚未和原NRF的注册/订阅NF建立交互，无法把原NRF故障信息通知给NF。
而如果通过NF与原NRF交互流程中检测NRF故障，则每个NF均需要等到与NRF交互发生时，才能检测到NRF的故障，之后NF需一一和备用NRF建立交互，这将影响到多个NF的功能和流程。
下面结合附图及实施例对本示例实施方式进行详细说明。
图1示出本公开实施例中一种网络存储功能故障检测及容灾方法流程图，如图1所示，本公开实施例中提供的网络存储功能故障检测及容灾方法，包括如下步骤：
在S102中，在第一NF向第二NRF发送第一注册请求后，向第一NRF发送第一订阅请求。
第一订阅请求用于订阅第二NRF的故障通知服务。第一订阅请求可以是NF注册请求。
第一NRF也可以称为备用NRF，第二NRF也可以称为原NRF。
在一些实施例中，第一NF注册到第二NRF或订阅第二NRF服务，第一NRF为第二NRF的备份NRF，在第二NRF故障时，注册到第二NRF或订阅第二NRF服务的NF可以迁移至第一NRF。
在S104中，第一NRF在确定第二NRF发生故障后，向第一NF发送故障通知。
在S106中，第一NF响应于故障通知，容灾迁移到第一NRF。
在第二NRF故障的情况下，第一NF与第一NRF建立交互，容灾迁移到第一NRF。
需要说明的是，在第二NRF正常期间，第二NRF与第二NRF间可以进行信息同步。
本公开实施例的网络存储功能故障检测及容灾方法适用于5G网络系统。
本公开实施例中第一NF向第一NRF订阅故障通知服务，该故障通知服务是针对第二NRF故障的通知服务，在第二NRF故障时，第一NRF会将第二NRF故障的信息发送至订阅了该故障通知服务的NF，包括第一NF。
第一NF，可以是5G系统架构的任一NF。
5G系统架构，可以包括如下NF：
鉴权服务器功能(Authentication Server Function，AUSF)负责用户鉴权数据相关的处理；
接入和移动性管理功能(Access and Mobility Management Function，AMF)负责用户的移动性和接入管理；
数据网络(Data Network，DN)运营商服务，互联网接入或第三方服务；
非结构化数据存储功能(Unstructured Data Storage Function，UDSF)存储任何NF的非结构化数据，例如AMF和SMF使用的会话ID、状态数据；
网络开放功能(Network Exposure Function，NEF)负责对外开放网络数据；
网络切片选择功能(Network Slice Selection Function，NSSF)负责管理网络切片相关的信息；
策略控制功能(Policy Control Function，PCF)负责策略控制；
会话管理功能(Session Management Function，SMF)负责用户会话管理；
统一数据管理(Unified Data Management，UDM)负责前台数据的统一处理，包括用户标识、用户签约数据、鉴权数据等；
统一数据存储(Unified Data Repository，UDR)存储结构化数据；
用户平面功能(User Plane Function，UPF)全权负责用户面的路由和转发功能；
应用功能(Application Function，AF)负责与3GPP核心网交互以提供服务；
安全边缘保护代理(Security Edge Protection Proxy，SEPP)负责PLMN间控制平面接口的信令消息过滤和监管，以及拓扑隐藏；
网络数据分析功能(Network Data Analytics Function，NWDAF)运营商 管理的网络分析逻辑功能，提供负载级别分析。
本公开实施例在现有NF failure发现机制上，提出了NF向第一NRF订阅第二NRF的故障通知，第一NRF在判断出第二NRF故障后，主动把故障通知发送给注册在第二NRF或订阅了第二NRF服务的NF，并主动触发这些NF的NRF容灾迁移，把这些注册/订阅NF迁移到第一NRF上。
本公开实施例采用第一NRF来判断第二NRF是否发送故障，并把故障通知发送给注册在第二NRF或订阅第二NRF服务的NF。这样避免了这些NF需要各自判断第二NRF是否发生故障，能让这些NF快速知道第二NRF故障，并迁移到第一NRF上。
在一些实施例中，故障通知是在第二NF与第二NRF之间交互失败，第一NRF确定第二NRF故障时，发送至第一NF的。
第二NF为注册在第二NRF或订阅了第二NRF服务的NF。
在一些实施例中，第二NF与第二NRF之间交互失败的情况，包括如下一种或多种：
第二NF向第二NRF注册失败、第二NF向第二NRF去注册失败、第二NF向第二NRF订阅失败、第二NF向第二NRF去订阅失败。
在一些实施例中，上述方法还可以包括：
在与第二NRF之间交互失败的情况下，确定第二NRF故障；
在确定第二NRF故障的情况下，容灾迁移到第一NRF。
在一些实施例中，在如下情况下，可以确定第二NRF故障：
第一NF接收到第一NRF发送的故障通知，和/或，第一NF与原NRF之间交互失败。其中，故障通知可以是在第二NF与第二NRF之间交互失败，第一NRF确定第二NRF故障时，发送至第一NF的。
也就是说，第一NF可以通过接收第一NRF的通知，来确定第二NRF是否故障，也可以通过自身与第二NRF之间的交互来确定第二NRF是否故障。
在一些实施例中，第一NRF在确定第二NRF故障后，还可以查找目标NF，目标NF为注册在第二NRF或订阅了第二NRF服务的NF，目标NF的数量不限，可以是一个或多个；然后，第一NRF可以向目标NF，发送故障通知，以使目标NF容灾迁移到第一NRF。
在一些实施例中，容灾迁移到第一NRF，包括将第二NRF服务的NF重新通过第一NRF来进行NF注册和/或服务订阅。
图2示出本公开实施例中一种网络存储功能故障检测及容灾方法流程图，如图2所示，本公开实施例中提供的网络存储功能故障检测及容灾方法，包括如下步骤：
在S201中，第一NF注册到第二NRF或订阅第二NRF服务。
在S202中，第一NF向第一NRF订阅第二NRF的故障通知服务。
第一NF订阅后，第一NRF会及时将第二NRF的故障信息发送至第一NF。
在S203中，NRF间信息同步，也就是第二NRF和第一NRF之间进行信息同步。
在第二NRF故障之后，第一NF可以通过与第二NRF之间的交互来确定第二NRF是否故障，也就是下面的步骤S204-S205。
在S204中，第一NF与第二NRF交互失败，发现第二NRF故障。
在S205中，第一NF容灾迁移到第一NRF。
图3示出本公开实施例中一种网络存储功能故障检测及容灾方法流程图，如图3所示，本公开实施例中提供的网络存储功能故障检测及容灾方法，包括如下步骤：
在S301中，第二NF与第二NRF交互失败，发现第二NRF故障。
需要说明的是，在S301之前，第一NF和第二NF注册到原NRF或订阅第二NRF服务，且第一NF向第一NRF订阅第二NRF的故障通知服务。第二NF也可以向第一NRF订阅第二NRF的故障通知服务。第二NRF和第一NRF之间进行信息同步。
在S302中，第二NF容灾迁移到第一NRF。
在S303中，第一NRF确定第二NRF故障，然后查找第二NRF中注册/订阅的NF相关信息，找到注册在第二NRF或订阅了第二NRF服务的目标NF。
在S304中，向目标NF(包括第一NF)发送第二NRF故障通知。
在S305中，第一NF容灾迁移到第一NRF。
本公开实施例所提供的网络存储功能故障检测及容灾方法，第一网络功 能NF向第一网络存储功能NRF订阅第二NRF的故障通知服务，采用第一NRF来判断第二NRF是否发送故障，如此，在第一NRF已经通过其它NF发现第二NRF故障的情况下，第一NF便可以通过第一NRF快速知道第二NRF故障，无需自行判断第二NRF是否发生故障。

本公开中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
此外，尽管在附图中以特定顺序描述了本公开中方法的各个步骤，但是，这并非要求或者暗示必须按照该特定顺序来执行这些步骤，或是必须执行全部所示的步骤才能实现期望的结果。
