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 method of operating a mobile device, comprising:
operating a plurality of logical channel queues, each of the logical channel queues associated with a priority and a traffic shaping rate;
selecting, from the plurality of logical channel queues, a highest priority logical channel queue having data for transmission and whose traffic shaping rate is not reached;
allocating a portion of a data transmission capacity available to the mobile device, to the selected logical channel queue, wherein the allocated portion is limited by:
the traffic shaping rate associated with the selected logical channel queue,
the data available for transmission in the selected logical channel queue, and
the data transmission capacity;
repeatedly considering a next highest priority logical channel queue for selecting and allocating, until at least one of:
the data transmission capacity is exhausted, and
each of the plurality of logical channel queues is considered for selecting; and thereafter
allocating a remaining portion, if any, of the data transmission capacity to one or more of the logical channel queues having data for transmission, selected in priority order.
2. A method as claimed in claim 1 , wherein the traffic shaping rate includes a prioritized data rate and a leaky bucket size.
3. A method as claimed in claim 1 wherein the portion of data transmission capacity is all of the data transmission capacity.
4. A method as claimed in claim 1 , wherein the data transmission capacity may change from a first frame to a second frame.
5. A method as claimed in claim 1 , wherein allocating further includes segmenting a data packet if necessary to fit the data packet within the portion of the data transmission capacity allocated to the respective logical channel queue.
6. A method as claimed in claim 1 , wherein the data transmission capacity is allocated by a base station to the mobile device in an uplink frame.
7. A mobile device for transmitting data using a data transmission capacity, comprising:
a link controller operable to:
operate a plurality of logical channel queues for transmitting data, each of the logical channel queues is capable of being associated with a priority and a traffic shaping rate,
select, from the plurality of logical channel queues, a highest priority logical channel queue having data available for transmission and whose traffic shaping rate is not reached,
allocate a portion of the data transmission capacity to the selected logical channel queue, wherein the allocated portion is limited by the traffic shaping rate associated with the selected logical channel queue, by the data available for transmission in the selected logical channel queue, and by the data transmission capacity,
repeatedly consider a next highest priority logical channel queue to select and allocate, until at least one of: the data transmission capacity is exhausted, and each one of the plurality of logical channel queues is considered, and thereafter
allocate a remaining portion, if any, of the data transmission capacity to one or more of the logical channel queues having data for transmission, selected in priority order; and
a radio transceiver for transmitting and receiving data, wherein the radio transceiver transmits the data according to the link controller allocation.
8. A mobile device as claimed in claim 7 , wherein the traffic shaping rate includes a prioritized bit rate and a leaky bucket size.
9. A mobile device as claimed in claim 7 wherein the portion of data transmission capacity is all of the data transmission capacity.
10. A mobile device as claimed in claim 7 , wherein the data transmission capacity may change from frame to frame.
11. A mobile device as claimed in claim 7 , wherein allocate further includes segment a data packet if necessary to fit the data packet within the portion of the data transmission capacity allocated to the respective logical channel queue.
12. A mobile device as claimed in claim 7 , wherein the data transmission capacity is allocated by a base station to the mobile device.
