A user equipment is initially camped on an LTE/E-UTRAN cell (205). An eNodeB informs (210) the UE to return after circuit-switched fall-back, CSFB, and optionally provides re-direction/re-selection information. The UE then performs a CSFB (215) with a NodeB of a legacy network cell, such as GERAN/UTRAN/CDMA2000 cell. Upon release of the CSFB connection (220), the UE uses (230) the received re-direction information to identify a best cell candidate in LTE, and select back (235) to the LTE/E-UTRAN carrier. |
