发明名称 Cleanup of LAU-less circuit switched fallback emergency call
摘要 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.

主权项 1. A method, comprising: detecting, for an extended service request for a mobile originated circuit switched fallback by a user equipment, that the circuit switched fallback is due to an emergency; and marking an interface association for the user equipment as not valid based on it being detected that the circuit switched fallback is due to an emergency.
