1. A method comprising:
at a first user plane function (UPF) node for use in a mobile network, receiving a data packet from a user equipment (UE) which is operative to communicate via a serving base station (BS) of the mobile network in one or more protocol data unit (PDU) sessions anchored at the UPF node, wherein the data packet is associated with a first PDU session anchored at the UPF node;
receiving a first packet transmitted by the UE, the first packet indicating a change to the first PDU session associated with the UE;
triggered by and responsive to the first packet, accessing, by a session management function (SMF) node, information from a network data analytics function (NWDAF) node, the information including analytics data for PDU session migration of the first PDU session to a different UPF node; and
causing, by the SMF node, migration of the first PDU session to a different UPF node based on the information obtained from the NW DAF node.
