Solutions pertaining to user equipment (UE) behavior for failed registration request or service request for emergency services fallback in mobile communications are proposed. An apparatus implemented in a UE determines a failure in attempting to initiate a mobility registration request procedure or a service request procedure with a network to perform an emergency service fallback. In response to the determining, the apparatus performs one or more operations including at least a UE non-access-stratum (NAS) layer in a 5Generation Mobility Management (5GMM) protocol informing an upper layer in the 5GMM protocol of the failure to cause the upper layer to attempt an emergency call in a different domain or via a different network.

UE behavior for failed registration request or service request for emergency services fallback

Solutions pertaining to adjusted public land mobile network (PLMN) search in mobile initiated connection only (MICO) mode in mobile communications are proposed. An apparatus implemented in a UE activates a MICO mode. The apparatus then postpones a periodic PLMN search in response to the UE being in the MICO mode, with the periodic PLMN search being controlled by a timer.
