Abstract
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.
