Abstract
A method of handling mapped Evolved Packet System (EPS) bearer context for invalid QoS flow description is proposed. During a PDU session establishment procedure or a PDU session modification procedure, a UE may receive a mapped EPS bearer context IE for creating a new mapped EPS bearer of a PDU session. If there is no corresponding QoS flow description associated to the new mapped EPS bearer, e.g., if there is no corresponding authorized QoS flow description IE in the PDU session establishment accept message or in the PDU session modification command message, then the UE should send another PDU session modification request message to the network to delete the new mapped EPS bearer context.
