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 implemented at a first NF node includes receiving a subscription request of an event for a user equipment, UE, from a third NF node; transmitting, to a second NF node that serves the UE, a subscription report request for the event for the UE; receiving, from a fourth NF node that currently serves the UE, a UE registration request for the UE, including an indication indicating whether the UE is in a restricted service area; and determining whether to transmit a notification for the event to the third NF node based on the UE registration request. The present disclosure further discloses a corresponding method implemented at the second NF node. The present disclosure further provides corresponding computer readable medium.
