    摘要： A method performed by a network node for transferring Protocol Data Unit (PDU) sessions of a User Equipment (UE) during a mobility procedure in which the UE is moved from a Fifth Generation System (5GS) to an Evolved Packet System (EPS) is disclosed. The method comprises one or more of determining that a target Mobility Management Entity (MME) for the mobility procedure in the EPS supports a first number of EPS Bearers that is less than a second number of EPS Bearer Identities (EBIs) assigned to a number of PDU sessions (e.g., and their associated Quality of Service (QoS) Flows) of the UE that are to be transferred from the 5GS to the EPS; determining which of the PDU sessions and/or QoS Flows of the UE are not to be transferred to the target MME; and releasing, requesting the release of or initiating release of the PDU sessions and/or QoS Flows that are not to be transferred to the target MME.
