Abstract
In the method of recognizing fraudulent emergency calls from a mobile station, a mobile station originating an emergency call is identified based on a mobile equipment identity received from the mobile station. A count of emergency calls received from the identified mobile station is generated and an incoming emergency call from the identified mobile station is determined as fraudulent based on the count.
