Abstract
A cell reselection technique establishes a data call on a different radio access technology (RAT) when a background application requests initiation of a data call while camped on a serving RAT. Rather than setting up the data call immediately on the serving RAT, a user equipment (UE) determines signal quality of the other RAT. When the signal quality is good, the UE delays call setup until after reselecting to the other RAT.
