Abstract
A user equipment (UE) speeds up circuit switched fallback call establishment and reduces circuit switched fallback call establishment failure. In one instance, the UE receives a redirection command including a list of current neighbor cells/frequencies. The UE determines whether a current serving cell matches a previous serving cell stored in the UE. The UE also evaluates the list of current neighbor cells to determine whether each current neighbor cell matches a previous neighbor cell associated with the previous serving cell. The UE then determines neighbor cells for power scan and/or synchronization channel decoding procedures to select one of the current neighbor cells to redirect the UE based on the previously recorded type of redirection result.
