BASE STATION IDENTITY CODE AND SYSTEM INFORMATION COLLECTION
First Claim
1. A method of wireless communication, comprising:
- receiving a redirection command from a serving cell of a serving RAT (radio access technology), the redirection command including a list of current neighbor frequencies corresponding to current neighbor cells of a neighbor RAT;
determining whether a cell identification for the serving cell and a stored serving cell identification of a previous serving cell are matched, the previous serving cell associated with previous neighbor frequencies corresponding to previous neighbor cells, the previous neighbor cells associated with previously recorded types of redirection results;
evaluating the list of current neighbor frequencies to determine whether each current neighbor cell matches a previous neighbor cell; and
determining current neighbor cells for power scan and/or synchronization channel decoding procedures to select one of the current neighbor cells to redirect a UE (user equipment) based at least in part on the previously recorded types of redirection results.

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.
