Original Abstract Submitted
Methods, network nodes, and computer readable storage media for ensuring uniqueness of an assigned PDU Session ID are disclosed. The method at a first network node includes: transmitting, to a second network node, during establishment of a Packet Data Network (PDN) connection, a request message for retrieving a list of PDU Session ID(s) that have been already registered for a User Equipment (UE); and receiving a response message from the second network node. The second network node is a Unified Data Management (UDM).
