Abstract

Various methods, apparatuses and/or articles of manufacture are provided which may be implemented as part of a mobile device to selectively transition operation of the mobile device from one communication mode to another communication mode. For example, a mobile device may selectively transition operation from one communication mode to another communication mode based, at least in part, on a determination that certain signaling environment attributes which were previously experienced and identified may once again have been experienced and identified.
