Methods, network function nodes and computer readable media for event subscription management

Abstract

The present disclosure provides methods for event subscription management in a network comprising a set of NF nodes, and corresponding NF nodes. The method comprises receiving a subscription request of an event for a user from an event subscriber, in response to receipt of the subscription request, transmitting, to a second network function node, a query request for querying whether the event for the user has been subscribed; and if a response to the query request from the second network function node indicates that the event for the user has been subscribed, transmitting, to the second network function node, an updating request for updating a subscriber list of the event for the user by the second network function node to include the event subscriber into the subscriber list. The present disclosure further discloses a corresponding method which comprises receiving a query request from a first network function node for querying whether an event for a user has been subscribed, in response to reception of the query request, checking whether an indicator indicating the event for the user has been subscribed has been set, and transmitting a check result to the first network function node. The present disclosure further provides corresponding computer readable medium.
