A method for transmitting data, comprising: detecting a plurality of different first Internet Protocol, IP, flow connections for a first application, wherein each IP flow connection of the plurality of first IP flow connections has assigned a respective QoS-IP flow priority indicator; determining a first QoS-IP flow priority indicator that is assigned to a first IP flow connection of the detected plurality of first IP flow connections; identifying the first application, wherein the first IP flow connection is targeted to the first application; storing the determined first QoS-IP flow priority indicator with a corresponding reference referring to the first application and referring to the first IP flow connection if the first QoS-IP flow priority indicator is not a default QoS-IP flow priority indicator; detecting a plurality of different second IP flow connections for a second application, wherein each IP flow connection of the plurality of second IP flow connections has assigned a respective QoS-IP flow priority indicator; determining a second QoS-IP flow priority indicator that is assigned to a second IP flow connection of the detected plurality of second IP flow connections; identifying the second application, wherein the second IP flow connection is targeted to the second application; storing the determined second QoS-IP flow priority indicator with a corresponding reference referring to the second application and referring to the second IP flow connection if the second QoS-IP flow priority indicator is not the default QoS-IP flow priority indicator; an application of the first application and the second application generating data to be transmitted via an IP flow connection; identifying the application which generates the data to be transmitted; selecting a stored QoS-IP flow priority indicator if the QoS-IP flow priority indicator is stored with a corresponding reference referring to the application and referring to the IP flow connection; selecting a stored default QoS-IP flow priority indicator if no QoS-IP flow priority indicator is stored with a corresponding reference referring to the application and referring to the IP flow connection and if a QoS-IP flow priority indicator referring to the IP flow connection is the default QoS-IP flow priority; and transmitting the generated data via the IP flow connection based on the selected QoS-IP flow priority indicator. detecting a plurality of different first Internet Protocol, IP, flow connections for a first application, wherein each IP flow connection of the plurality of first IP flow connections has assigned a respective QoS-IP flow priority indicator; determining a first QoS-IP flow priority indicator that is assigned to a first IP flow connection of the detected plurality of first IP flow connections; identifying the first application, wherein the first IP flow connection is targeted to the first application; storing the determined first QoS-IP flow priority indicator with a corresponding reference referring to the first application and referring to the first IP flow connection if the first QoS-IP flow priority indicator is not a default QoS-IP flow priority indicator; detecting a plurality of different second IP flow connections for a second application, wherein each IP flow connection of the plurality of second IP flow connections has assigned a respective QoS-IP flow priority indicator; determining a second QoS-IP flow priority indicator that is assigned to a second IP flow connection of the detected plurality of second IP flow connections; identifying the second application, wherein the second IP flow connection is targeted to the second application; storing the determined second QoS-IP flow priority indicator with a corresponding reference referring to the second application and referring to the second IP flow connection if the second QoS-IP flow priority indicator is not the default QoS-IP flow priority indicator; an application of the first application and the second application generating data to be transmitted via an IP flow connection; identifying the application which generates the data to be transmitted; selecting a stored QoS-IP flow priority indicator if the QoS-IP flow priority indicator is stored with a corresponding reference referring to the application and referring to the IP flow connection; selecting a stored default QoS-IP flow priority indicator if no QoS-IP flow priority indicator is stored with a corresponding reference referring to the application and referring to the IP flow connection and if a QoS-IP flow priority indicator referring to the IP flow connection is the default QoS-IP flow priority; and transmitting the generated data via the IP flow connection based on the selected QoS-IP flow priority indicator.
