Agent, server, core network node and methods therein for handling an event of a network service deployed in a cloud environment

An agent for handling an event of a network service deployed in a cloud environment, the agent comprising:

• a processor;
• and
• a memory containing instructions which, when executed by the processor, cause the agent to:
• obtain from a server, information about the event of the network service, wherein the server manages network services in the cloud environment, of which the network service being one of the network services managed by the server, and wherein the server tracks the network services and respective instances of the network services in the cloud environment;
• in response to the network service being related to a network specified by a Third Generation Partnership Project (3GPP) standard, decide to register the network service in a core network node of a core network that operates within the network specified by the 3GPP standard, along with an address of a load balancer associated with the network service;
• and
• register, by the agent, in the core network node of the core network, the network service according to the event, along with the address of the load balancer associated with the network service.

A core network node of a core network operable within a network specified by a Third Generation Partnership Project (3GPP) standard, for handling an event of a network service deployed in a cloud environment, the core network node comprising:

• a processor;
• and
• a memory containing instructions which, when executed by the processor, cause the core network node to:
• receive from an agent that communicates with a server, information of the network service according to the event, wherein the server manages network services in the cloud environment, of which the network service being one of the network services managed by the server, wherein the server tracks the network services and respective instances of the network services in the cloud environment, and wherein, in response to the network service being related to the network specified by the 3GPP standard, the server provides information about the network service for the event, along with an address of a load balancer associated with the network service, to the agent in order for the agent to register the network service according to the event, along with the address of the load balancer associated with the network service, in the core network node of the core network.
