Abstract:
Methods and systems are provided for aging EV-DO pages in a queue based on latency-sensitivity. An access node receives data for access terminals, and responsively generates pages and adds them to the back of a queue. The access node associates a respective aging value with any latency-tolerant pages. The access node transmits the pages in the queue, which involves: (a) assessing the pages on a first-in, first-out basis; (b) transmitting latency-sensitive pages when those pages reach the front of the queue; (c) sending latency-tolerant pages to the back of the queue (and incrementing their aging values) when those pages reach the front of the queue with an aging value that is less than a maximum-delay parameter; and (d) transmitting latency-tolerant pages when those pages reach the front of the queue with an aging value that is greater than or equal to the maximum-delay parameter.
