Abstract

To accelerate the specification of a location during the sending of an emergency call of a mobile telecommunications device (in particular, a terminal), the position of the respective mobile telecommunications device is determined prior to the sending of the call and/or independently of the mobile telecommunications network and is transmitted when the emergency call is sent.
