A method at a user equipment in an LTE system includes selecting one of a number of CDMA systems, and signaling indication(s) of the selected CDMA system to a network element. The network element receives indication(s) of CDMA system(s), which correspond to requested action(s) by a UE. The network element routes information corresponding to the requested action(s) to the CDMA system(s). Another network element in the LTE system signals to the UE indications of a mapping of a number of CDMA systems to associated ones of LTE system(s). The other network element receives signaling from the UE including indication(s) of selected CDMA system(s) selected by the UE.
