Claim:
1. A method for improved reselection during mode transitions at a user equipment (UE), comprising: performing, at the UE, inter-radio access technology (IRAT) cell reselection measurements, wherein the IRAT cell reselection measurements are associated with a cell reselection from a first radio access technology (RAT) to a second RAT; identifying, at the UE, a switching of the UE from an all priority scheduling mode to a high priority scheduling mode or from a high priority scheduling mode to an all priority scheduling mode, wherein the switching is identified while the IRAT cell reselection measurements are in progress, and wherein the switching is based at least on changes in signal quality of a serving cell of the UE or mobility of the UE; initiating, at the UE, a mode transition timer at the UE in response to the identification, wherein the mode transition timer is set to a value between zero and less than a first value when the UE is switching from the all priority scheduling mode to the high priority scheduling mode or zero and less than a second value when the UE is switching from the high priority scheduling mode to the all priority scheduling mode, and wherein the first value is set to a value of T triggering, at the UE, a search for one or more frequencies of the high priority scheduling mode or one or more frequencies of the all priority scheduling mode upon expiration of the mode transition timer.
