Abstract

An apparatus, system and method are provided for transmitting data from logical channel queues over a telecommunications link, each of the logical channel queues capable of being associated with quality of service attributes, the method including determining available resources for transmission over the telecommunications link in a frame; selecting one of the logical channel queues based on a first one of the quality of service attributes; packaging data from the selected one of the logical channel queues until one of: a second one of the quality of service attributes for the selected one of the logical channel queues is satisfied, the available resources are used, or the selected one of the logical channel queues is empty; and repeating the selecting step and the packaging step for remaining ones of the logical channel queues.

Claims

1. A base station, comprising:

a reassembly controller

operable to receive, over a single dedicated channel, a plurality of segmented packets from a wireless subscriber station, each respective segmented packet of the plurality of segmented packets associated with a respective quality of service (QoS), the single dedicated channel carrying segmented packets associated with a plurality of logical channel queues,

operable to reassemble the plurality of segmented packets to form a higher layer packet, and

operable to forward the higher layer packet towards a destination; and

a QoS processor operable to prioritize packets for transmission.

2. The base station of claim 1 wherein the reassembly controller comprises:

a plurality of reassembly queues operable to receive segmented packets of the plurality of segmented packets and to reassemble segmented packets to form a higher layer packet; and

a sequencer operable to place each respective segmented packet of the plurality of segmented packets into a reassembly queue associated with the segmented packet.

3. A method for operating a base station, the method comprising:

receive, over a single dedicated channel, a plurality of segmented packets from a wireless subscriber station, each respective segmented packet of the plurality of segmented packets associated with a respective quality of service (QoS), the single dedicated channel carrying segmented packets associated with a plurality of logical channel queues;

reassemble the plurality of segmented packets to form a higher layer packet; and

forward the higher layer packet towards a destination.
