Embodiment Construction
[0036] The preferred embodiment of the present invention prioritizes Logical Link Control (LLC) Packet Data Units (PDUs) when communicating user data over the radio interface between a Mobile Station (MS) and the GPRS network. According to the invention, LLC PDUs are reordered according to their requirements.
[0037] According to one embodiment of the present invention, Radio Link Control / Medium Access Control (RLC / MAC) can reorder LLC PDUs within an RLC / MAC, and LLC associates a Packet Data Protocol (PDP) context with an LLC service access Point Indicator (SAPI) intelligently linked. The invention allows prioritizing an LLC PDU in RLC / MAC and thus allows applications to receive their required Quality of Service (QoS). Based on the additional QoS information received with the LLC PDUs, the RLC / MAC unit can prioritize the LLC PDUs according to their urgency in transmission relative to other LLC PDUs.
[0038] According to another embodiment of the present invention, LLCPDUs ...
