Abstract

A method performed in a first network node includes the first network node transmitting, to a second network node, a first message including a user equipment (UE) status request of a UE. The method further includes the first network node receiving, from the second network node, a second message including a UE status response. The method also includes the first network node determining, based on the received UE status, whether to modify an PDN connection and/or a corresponding IP-CAN session associated with the UE.
