Abstract
A method, an apparatus, and a computer program product for wireless communication are provided in which user equipment performs a circuit-switched fallback procedure to connect to a CDMA2000 network. The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability.
