Description

Operation method for network function instance and related equipment Technical Field The present invention relates to the field of infrastructure and IT production technology, and in particular, to an operating method, apparatus, electronic device, computer readable storage medium, and computer program product for network function instances. Background In a fifth generation mobile communication (5G) Network architecture, dynamic registration and deregistration of a Network Function (NF) instance are core links for ensuring normal coordination of Network functions and stable operation of services. The network function register (Network Repository Function, NRF) is used as a key network element in the 5G core network, and bears the functions of centralized storage, management and query service of NF instance registration information, and after all NF instances are registered through the NRF, the NF instances can be found out and establish a service interaction relationship by other NF instances, and the accuracy of the maintained registration information directly determines the overall operation efficiency of the network. However, in the existing 5G network operation and maintenance practice, when the NF instance cannot normally provide services due to hardware failure, software abnormality, link interruption and the like, if the registration information of the NF instance cannot be removed from the NRF in time (i.e. the deregistration operation is completed), other normal NF instances in the network still initiate service requests to the failed NF instance based on the invalid registration information stored by the NRF, so that problems such as service request timeout, data transmission failure, service quality degradation and the like are caused, and network-level service interruption may be triggered when serious, which causes great influence on the reliability of communication service. Currently, a traditional mode of 'intranet network management access+manual Operation' is generally adopted by each telecom operator for registration management of an NF instance, and the specific flow is that Operation and maintenance personnel need to log in an Operation and maintenance center (Operation AND MAINTENANCE CENTER, OMC) system of a designated manufacturer through a special intranet and then access a target NRF network element, a current registration state of the target NF instance is obtained through inquiring a Man-Machine Language (MML), for example, the current registration state of the target NF instance in an access and mobility management function (ACCESS AND Mobility Management Function, AMF) network element with the number of AMF01 in a core network of a certain province is obtained, when fault alarms (such as equipment offline alarms) or key performance indexes (Key Performance Indicator, KPIs) such as session establishment success rate dip) of the target NF instance are monitored, a registration class MML instruction is manually executed to remove the target NF instance from the NRF, and after the target NF instance is isolated and repaired, the registration class MML instruction is executed through the same path to recover the registration state of the target NF instance in the NRF. The traditional management mode has the remarkable defects that the whole registration/removal operation depends on multi-system login and multi-step manual intervention, a long time difference exists from fault discovery to completion of operation, the real-time requirement of a 5G network on fault processing cannot be met, and particularly in a high-concurrency fault scene, the fault influence range is easily enlarged due to operation delay. Disclosure of Invention The invention mainly aims to provide an operation method for a network function instance and related equipment, and aims to solve the problem that the registration/deregistration operation efficiency of an NF instance is low in the prior art. The embodiment of the application adopts the following technical scheme: An operation method for a network function instance comprises the steps of sending a first 5G message to an operation and maintenance party to inquire whether a NF instance of the target network element is subjected to corresponding operation matched with an operation condition when the target network element with the operation condition is monitored, sending an operation instruction to an operation and maintenance center OMC if the operation and maintenance party confirms that the NF instance is subjected to the corresponding operation, wherein the operation instruction is used for triggering the OMC to execute the corresponding operation on the NF instance in a network function register NRF, the operation condition is failure or failure elimination, and the corresponding operation is deregistration or registration. An operation method aiming at a network function instance comprises the steps of receiving a first 5G message, inquiring whether to
