    Abstract: A method for application-specific traffic handling is provided. A service data unit (SDU) can be received at a radio protocol layer in a radio access network (RAN) protocol stack. The SDU carries application data that is generated from an application layer and passes through multiple protocol layers existing between the application layer and the radio protocol layer. At the radio protocol layer, the SDU is inspected to obtain characteristic information from one or more protocol headers corresponding to one or more protocol layers among the multiple protocol layers. The characteristic information indicates characteristics of the application data. At the radio protocol layer, the SDU is classified into one of multiple classes based on the characteristic information obtained from the one or more protocol headers.
