An MA PDU session uses one 3GPP access network or one non-3GPP access network at a time, or simultaneously one 3GPP access network and one non-3GPP access network. Upon receiving a PDU session release command message including an access type, the user equipment (UE) transmits a PDU session release complete message or a 5G session management (5GSM) status message to the 5G system (5GS). In addition, the UE determines the user plane resources of the MA PDU session on the access indicated in the access type as released, or determines the MA PDU session as released, depending on the access indicated in the access type and the access(es) over which the user plane resources of the MA PDU session are established."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhancement for multi-access PDU session release","description":"A method for handling multi-access (MA) Protocol data unit (PDU) session release is proposed.
