A method of handling QoS error in an evolved packet system (EPS) session management (ESM) procedure to support interworking from EPS to 5G system (5GS) is proposed. A UE receives 5GSM parameters of QoS rule(s) and/or QoS flow description(s) included in a PCO/ePCO IE in an ESM message for performing a QoS operation. During the ESM procedure, only 5G QoS parameters related to the current EPS bearer been activated or modified are allocated and sent to the UE via PCO/ePCO. Otherwise, an operation error may occur for the QoS operation. Accordingly, the operation error is detected by the UE before intersystem change from S1 mode to N1 mode happens and the UE indicates such error to the network with a cause value.

A wireless device determines a change in a signal quality measurement of a wireless network. In response to the determining, a first message for changing one or more media for a video call in the wireless network is transmitted from the wireless device to a video application function (AF). A policy and charging rules function (PCRF) receives from the video AF, a DIAMETER AA-request (AAR) command for modifying a quality of service (QoS) of the video call. The PCRF transmits to a policy and charging enforcement function (PCEF), a second message comprising an updated QoS, wherein the updated QoS comprises QoS data bearer modification information based on the change in the signal quality measurement of the wireless network. The PCEF implements the updated QoS for the video call.
