REDIRECTION HISTORY BASED CIRCUIT SWITCHED FALL BACK ACROSS MOBILE SWITCHING CENTER POOLS

摘要

A user equipment (UE) receives a circuit switched page from a first base station of a first radio access technology (RAT) and a command instructing the UE to redirect from the first base station to a second RAT. The UE identifies a second base station of the second RAT in response to receiving the command. The second base station is the strongest base station in the second RAT and has a location area code. The UE determines whether the location area code corresponds to a location area code associated with a previous successful redirection attempt from the first base station. The UE redirects to the second RAT based at least in part on the determining.
