The invention relates to a method and a device for improving the processing time
of received data in packet oriented applications during a transmission via communication
networks, in particular via an IP network and a mobile communication network such
as the Global System for Mobile Communication (GSM), Universal Mobile Telecommunication
System (UMTS) or General Packet Radio Service (GPRS). The received data packets
of the second protocol layer, for instance, the RLP frames, are combined to form
data packets of the first protocol layer, for instance to PPP frames, directly
by the receiver in the second protocol layer. The completely and correctly combined
data packets are then released to the first protocol layer. During the release
of the data packets to the first protocol layer, a difference is made between two
modes. The intra-flow mode is a mode, wherein all completely generated data packets
are released, i.e. independent from whether the data packets belong to the same
or to two different data flows. In contrast thereto, a difference is made in view
of the inter-flow mode. In said mode only the completely generated data packets
belonging to different data flows are released to the first protocol layer.
