摘要
A method of handling QoS flow descriptions with invalid EPS bearer context is proposed. During an EPS bearer activation or modification procedure, a UE may receive an ePCO/PCO IE for creating a new QoS flow description or modifying an existing QoS flow description. if UE detects that the to be created/modified QoS flow descriptions are associated with invalid EPS bearer context, then UE does, not create/modify the QoS flow descriptions. Instead, UE locally deletes the QoS flow descriptions provided by the network. In addition, UE indicates a 5GSM cause to the network via PCO/ePCO. As a result, when inter-system change from EPS to 5GS happens, UE no longer needs to handle the QoS flow descriptions with invalid EPS bearer context.
