Patent number: 8064938Abstract: System(s) and method(s) that, periodically or when triggered, adapt data rates in multiple tiers of a network are presented. A top tier feedback (FB) loop adapts on a longer time scale associated with its longer path transit time for FB communication messages from a wireless portion to a data source in the wire-line portion of the network. A bottom tier FB loop adapts very quickly, and on a shorter time scale that the top tier FB loop due to its shorter FB path transit time, at the wireless edge with sufficient speed to accurately adapt to fast-changing wireless conditions. The top tier provides efficient resource utilization down to the bottom tier, and the bottom tier provides efficient resource utilization within the wireless portion of the network. A middle tier(s) can be added as desired to provide a more gradual stepped adaptation from source to destination.Type: GrantFiled: March 31, 2009Date of Patent: November 22, 2011Assignee: AT&T Mobility II LLCInventors: Jeffrey A.

Patent number: 8064940Abstract: Apparatus (48), and an associated method, for facilitating operation of a mobile node (12) operable in a communication system (10) to request allocation of communication capacity upon which to communicate data pursuant to a communication service. A channel allocation request generator (52) is selectably operable to generate requests for allocation of channel capacity upon which to communicate the data. A selector (54) selects when to cause the generator (52) to communicate the additional data packets. Selection is made to delay, or otherwise prevent, retransmission of requests, when a determination is made that the retransmission is unlikely to be successful.Type: GrantFiled: November 16, 2010Date of Patent: November 22, 2011Assignee: Research In Motion LimitedInventors: Hongjun Zhang, Ashok Patel
