Abstract
Communication systems may benefit from various aspects of emergency call handing. For example, wireless communication systems may benefit from clean up with respect to a fast return feature applied to an emergency call using circuit switched fallback, without a location area update. A method may include identifying an emergency communication that is a circuit switched fallback communication of a user equipment. The method may also include configuring communications so that mobile terminated services work properly after completion of the emergency communication. More particularly, for example, a method may include determining in a network element that the emergency communication is a circuit switched fallback communication. The method may also include, when the emergency call is ended, avoiding invoking a fast return feature for the user equipment.
