A method of operation of a SMF in a 5GC, for synchronizing the GBR QoS flows with the UE is provided. The method comprises initiating deactivation of one or more GBR/non-GBR (not associated to a default QoS Rule), QoS flows of a PDU session in the 5GC and in the UE and upon determining that a response to the deactivation is not received from the UE, deferring, by the SMF, the deactivation of the one or more GBR/non-GBR QoS flows with the UE and marking the GBR/Non-GBR QoS flows as to be synchronized when either UP reactivation is received or UE reachability notification is received or upon a synchronization timer set by the SMF has expired. The GBR/non-GBR QoS Flows may also be locally deactivated at the UE, in which case a method in the UE to synchronize the GBR/non-GBR QoS flows with the 5GC is provided.
A method of operation of a network node implementing a Session Management Function, SMF, in a core network of a cellular communications system, comprising:
A method of operation of a wireless device with an established Packet Data Unit, PDU, Session with a Core network, and the PDU session comprising at least one of a Guaranteed Bit Rate, GBR, Quality of Service, QoS Flow and a non-Guaranteed non-GBR QoS flow that is not associated to a default QoS rule, the method comprises:
