Methods, systems, apparatuses and devices are described for managing a call during radio link failure. In one embodiment, radio link failure over a radio access technology may be detected during or after a call setup procedure. A public land mobile network and an equivalent public land mobile network may be selected. An initial search for cells of the radio access technology may be performed over the selected public land mobile network and the equivalent public land mobile network. The initial search may be performed once or twice based on a configurable parameter.

The present disclosure presents methods and apparatuses for managing Multimode System Selection in one or more user equipment in a wireless system. According to some aspects of the present disclosure, such a method may include discovering whether a user equipment (UE) contains at least one 3GPP network subscription and at least one 3GPP2 network subscription, determining whether 3GPP2 network subscription information is stored on a Universal Integrated Circuit Card (UICC) or a nonvolatile memory (NV) associated with the UE where the UE contains at least one 3GPP network subscription and at least one 3GPP2 network subscription, and performing a read operation on one or both of the UICC and NV to obtain one or more Multimode System Selection (MMSS) base files based on the determining.
