摘要： In an aspect of the disclosure, a user equipment (104, 710) and a method of performing a radio access technology network change by the user equipment (104, 710) are provided. In certain configurations, the user equipment (104, 710) performs first inter-system change from a first radio access technology network to a second radio access technology network. In response to failing the first inter-system change, the user equipment (104, 710) performs second inter-system change from the second radio access technology network to a third radio access technology network by performing an initial attach procedure or an initial registration procedure in the third radio access technology network.

摘要： Solutions pertaining to user equipment, UE, behavior for collisions between network-initiated de-registration/detachment and emergency service procedures in mobile communications are proposed. An apparatus implemented in a UE determines that a mobility and periodic registration update, MRU, procedure or a service request, SR, procedure triggered for initiating an emergency protocol data unit, PDU, session collides with a network-initiated de-registration procedure while the UE interfaces with a network (310). In response to the determining, the apparatus performs one or more operations comprising a UE non-access-stratum, NAS, layer in a 5th Generation Mobility Management, 5GMM, protocol stack informing one or more upper layers of the 5GMM protocol stack of a failure of the corresponding procedure such that an upper layer of the 5GMM protocol stack initiates a mechanism for remedying the failure, or performing a local de-registration and attempting an initial registration for emergency services in the network (320).

摘要： A method for managing an unavailability period performed by a user equipment (UE) is provided. The method comprises being registered in a network and choosing a substate of a deregistered state when an unavailability period is activated by the UE using a deregistration procedure or choosing a substate of a registered state when an unavailability period is activated by the UE using a registration procedure.
