Abstract: Apparatus, and an associated method, is provided to facilitate communications pursuant to an interactive packet radio communication service, such as an interactive gaming service. When data is to be communicated by a gaming device, or other mobile node, request for channel allocation is made. And, packet data generated at the gaming device is buffered at a buffer and selectably manipulated when buffered thereat pending grant of a channel allocation. Because the data is permitted to be manipulated pending grant of the channel allocation, data packets that become obsolete during the pendency are overwritten, or otherwise caused not to be sent, thereby more efficiently utilizing the channel allocation allocated to effectuate the communication service.
