Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media to address bearer loss during inter-radio access technology (RAT) handovers. A method includes sending a create bearer request for establishing a service for the mobile device using a first connection; receiving a create bearer response message to setup a second connection for the mobile device to continue the service; and, in response to the create bearer response message, sending an update bearer request message to provide the mobile device with the QoS information associated with the second connection, the QoS information allowing the mobile device to verify an existing QoS flow to continue the service after the handover. In some cases, a user equipment (UE) may delete a mapping between a QoS information when a previous message does not include an evolved packet core (EPC) bearer indicator (EBI) that identifies QoS policies.
