CIRCUIT SWITCHED FALL BACK REDIRECTION ACROSS MOBILE SWITCHING CENTER POOLS

摘要

A user equipment (UE) receives a circuit switched page from a first radio access technology (RAT) and a command instructing the UE to redirect to a second RAT. The command indicates a designated location area identity of the second RAT. The UE detects base stations of the second RAT and determines whether a strongest base station is in an area identified by the designated location area identity. The UE connects to the strongest base station based on the determining. When the designated location area identity is a permitted location area, the UE connects to the strongest base station when the location of the strongest base station is included in the permitted location area. When the designated location area identity is a prohibited location area, the UE connects to the strongest base station when the location of the strongest base station is not included in the prohibited location area.
