[0042] overview

[0043]Various aspects of the invention include improved methods and apparatus for delaying connection establishment and optimizing connection establishment behavior. More specifically, in one aspect of the invention, data is queued for a short period before a connection is established (instead of an idle connection being kept open for a fixed period after transmission). After the queuing period, the connection is established, the queued data is transferred, and then the connection is immediately closed. During queuing periods, during which there are no active connections (no resources consumed, no power used, etc.), queuing periods may be used as an effective alternative to idle mode operation.

[0044] In another aspect of the invention, transmission behavior is optimized according to a stochastic function that maximizes one or more desired properties (eg, po...

Abstract

Methods and apparatus for reducing data transmission. In one embodiment, rather than immediately transmitting first data, a first device postpones opening a data connection; any subsequently arriving data is queued with the first data, and transmitted together. Connection overhead is optimized by delaying connection establishment until it is necessary, and in some cases eliminating idle mode operation altogether. Stochastic embodiments are also disclosed for adjusting transmission behavior to maximize one or more desirable outcomes. For example, one such embodiment queues data for a stochastically determined period of time, prior to opening a data connection. The stochastically determined time interval balances the likelihood of efficiently servicing successively arriving data, and overall performance. Mechanisms for receiving and utilizing device user and / or receiver (e.g., base station) feedback are also disclosed.

Description

[0001] priority application [0002] This application claims priority to US Patent Application No. 12 / 850,884 of the same title filed on August 5, 2010, which is hereby incorporated by reference in its entirety. [0003] Copyright Notice [0004] Portions of the disclosure of this patent application contain material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or patent disclosure, as such, of USPTO files or records, but reserves the copyright interest regardless. technical field [0005] The present invention relates generally to the field of telecommunications. More specifically, in one illustrative aspect, the invention relates to methods and apparatus for reducing data transfer overhead by delaying the transfer of data. Background technique [0006] Most wireless communication systems establish a logical "connection" between a source device and a destination device (or netw...
