Abstract

See full text

A method executed by a User Equipment (UE) for emergency call handling during a de-registration or detach procedure is provided. The UE initiates a Mobility Management (MM) de-registration procedure or an MM detach procedure with a mobile communication network. The UE initiates an emergency service before the MM de-registration procedure or the MM detach procedure has been completed. In response to the initiation of the emergency call, the UE aborts the MM de-registration procedure or the MM detach procedure and performs local de-registration or local detach. After the local de-registration or the local detach, the UE initiates a registration procedure or an attach procedure.
