The method may be performed by a unified data management (UDM) node and comprise: receiving, from a first session management function (SMF) node, a first message including a first redundancy sequence number (RSN) which is allocated by the first SMF node for managing a first PDU session and an identifier of the first PDU session; transmitting, to a second SMF node for managing a second PDU session, a second message including the first RSN and a PDU session pair ID, which is identical to the identifier of the first PDU session; and receiving, from the second SMF node, a third message including a second RSN which is allocated by the second SMF node and an identifier of the second PDU session. The second PDU session may be duplication of the first PDU session."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for supporting redundant PDU sessions","description":"One disclosure of the present specification provides a method for supporting redundant protocol data unit (PDU) sessions.
