Various communication systems may benefit from improved quality of service flow. A method may include receiving an indication at a radio resource control entity or service data adaptation protocol layer entity in a radio protocol of a receiver from a transmitter. The indication can include instructions to relocate a quality of service flow from a source to a target data radio bearer. The method may also include starting a timer associated with the quality of service. In addition, the method may include buffering data packets received as part of the quality of service flow from the target data radio bearer during a duration of the timer. Further, the method may include allowing for the transmission of the buffered data packets of the quality of service flow received from the target data radio bearer to an upper protocol layer after the duration of the timer has lapsed or stopped.
