A Data Link Control protocol for 3G wireless communication system for direct support for network layer protocols, e.g. the Internet Protocol (IP), is provided. The Link Layer disclosed comprises a Link Access Control (LAC) sublayer and a Medium Access Control (MAC) sublayer. At a transmit end of the wireless system, a plurality of Quality of Service (QoS) data planes are created to directly support the IP QoS. Each QoS data plane is optimized to handle QoS requirements for a corresponding Class of Service (CoS). Data packets received at the LAC sublayer are directed to a QoS data plane according to the particular QoS information they contain and processed according to the particular QoS requirement to generate variable size LAC frames. The variable size LAC frames are transmitted to the MAC sublayer for generating radio link protocol data units (RLP PDUs) to be transmitted to a receiving end. A new level of error correction is provided at the LAC sublayer as the size of the LAC PDUs can be dynamically adjusted in response to the conditions of the communication link. A dual mode ARQ is provided at the MAC sublayer to improve the quality of the air transmission for bursty as well as non-bursty traffic conditions.

The method according to claim 1, wherein without an entered access authorization, the annularly chained memories are occupied with a further item of information not related to the access authorizations and which is individual to the network terminal unit. 4. The method according to claim 1, wherein the access authorizations of the network terminal units are entered into the annularly chained memories in such a way that accesses to the allocated partial communication network resources are optimized according to predetermined criteria. 5. The method according to claim 4, wherein the predetermined criterion represents a minimum delay of the accesses of the network units to the allocated partial communication network resources. 6. The method according to claim 1, wherein the annularly chained memories are sampled with a packet pulse of the packet-oriented communication network, and the access authorizations are read out. 7. The method according to claim 1, wherein a number of the annularly chained memories is determined dependent on a predetermined scope of the resources of the packet-oriented communication network and on an arbitrarily predeterminable scope of the partial communication network resources. 8. The method according to claim 1, wherein the packet-oriented communication network is realized by a communication network designed according to an asynchronous transfer mode. 9. The method according to claim 1, wherein the predetermined resources of the packet-oriented communication network are represented by transmission capacity of at least one of wire-bound, optical, and wireless transmission paths in a feeder network of the packet-oriented communication network.
