Apparatus, system and method for the transmission of data with different QoS attributes
View Patent ↗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.
1. A radio base station, communicating with a plurality of subscriber stations over a radio link established in a wireless network:
a prioritization engine ( 108 ) adapted to receive a packet, examine the packet to determine an appropriate set of quality of service attributes required for the packet, and classify the examined packet into one of a plurality of logical channel queues associated with one of the plurality of subscriber stations;
a radio link controller adapted to allocate at least one radio resource from a plurality of radio resources available in a current frame to the one of the plurality of subscriber stations, and use at least part of the radio resource to send at least one packet from one of the plurality of logical channel queues associated with the one of the plurality of subscriber stations.
2. A radio base station as in claim 1 , wherein the plurality of available resources comprises a pool of dedicated data channels and a pool of shared broadcast data channels.
3. A radio base station as in claim 2 , wherein the channels in the pool of dedicated data channels receive a different amount of data capacity than the pool of shared broadcast data channels.
4. A radio base station as in claim 2 , wherein channels are created and deleted dynamically in the pool of dedicated data channels.
5. A radio base station as in claim 2 , wherein channels are created and deleted dynamically in the pool of shared broadcast data channels.
6. A radio base station as in claim 2 , wherein channels are created and deleted dynamically in the pool of dedicated data channels.
7. A radio base station as claimed in claim 2 , wherein any logical channel queue of the plurality of logical channel queues is assignable to two or more of the available shared broadcast data channels that a destination subscriber station is receiving.
8. A radio base station as in claim 2 , wherein any logical channel queue of the plurality of logical channel queues is assignable to one of the available dedicated data channels.
9. A radio base station as in claim 1 , wherein the radio resource is allocated to the subscriber station for the duration of a session.
10. A radio base station as in claim 9 , wherein the radio resource allocated to the subscriber station changes during the session when the requirements for the session change.
11. A radio base station as in claim 9 , wherein the radio resource allocated to the subscriber station changes during the session when the amount of plurality of radio resources available change.
12. A radio base station as in claim 1 , wherein the radio link controller is further adapted to perform prioritization, segmentation and traffic shaping of data packets for transmission over the available radio resources.
