Problems solved by technology

The fundamental problem with existing technology is that RLC / MAC does not translate the contents of LLC PDUs at all, but only transmits over the radio interface e.g. LLC PDUs received from one LLC

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 ...

Abstract

A method and device according to the present invention reorders Logical Link Control (LLC) Packet Data Units (PDUs) when user data is transferred over the radio interface between a Mobile Station (MS) and a packet data network. An objection of the present invention is to provide a method and system for transferring user data over a network ensuring the best quality of service characteristics.

Description

technical field [0001] The present invention relates to the transfer of data over a radio interface in a General Packet Radio System (GPRS) network. technical background [0002] In wireless telecommunication systems, information is communicated over a radio interface between sending and / or receiving communication devices and a communication network. In general packet radio systems such as GPRS, Enhanced GPRS (EGPRS) and GSM Enhanced Data rate for Global Evolution (EDGE) Radio Access Network (GERAN) There are constant efforts in (GPRS) networks to improve the quality of data transfer and thus the quality of service (QoS). The term GPRS in this application also refers to EGPRS, GERAN and other improvements of GPRS. [0003] A mobile station (MS), a base station subsystem (BSS) consisting of a base transceiver station (BTS) and a base station controller (BSC) with a packet control unit (PCU), and a serving GPRS support node (SGSN) are used for The main part of the GPRS arch...
