Abstract:
A method, an apparatus, and a computer program product for wireless communication at a fourth generation (4G) capable user equipment (UE) include determining, when the 4G capable UE does not report a 4G capability but reports one or more other radio access technology (RAT) capabilities, a 4G service change possibility for the 4G capable UE, performing a 4G network search and measurement procedure in response to the determination of the 4G service change possibility, and performing a combined evolved packet system/circuit switched (EPS/CS) attach attempt procedure when the 4G network search and measurement procedure indicates a 4G network availability.
