Abstract:
1. An OFDMA-TDMA (Orthogonal Frequency Division Multiple Access-Time Division Multiple Access) based wireless Internet terminal comprising: a QoS profile storing information about a QoS policy; Media Access Control (MAC) layer software, comprising: MAC layer hardware, comprising: wherein the MAC layer software further comprises the plurality of QoS queues for dividing and storing the data packets classified by the classifier, and a plurality of priority queues for dividing and storing the data packets admitted by the admission controller based on their first priorities, wherein the classifier identifies the type of packet traffic and stores a data packet of the packet traffic in one of the plurality of QoS queues based on the QoS policy corresponding to the identified type, wherein the admission controller stores the data packet, which is determined for admission, in one of the plurality of priority queues and discards data packets that have a degree of importance lower than a predetermined degree based on a network state, and wherein the type of the packet traffic comprises at least one of audio data and burst data, and wherein the PDUs are MAC PDUs, and the second priority controller determines which one among an ACK packet, a management message packet and a user data packet, a corresponding packet is, based on headers or identifiers of the MAC PDUs and gives the second priories to the MAC PDUS in the order of the ACK packet, the management message packet and the user data packet independently from the QoS profile.
