Abstract
An emergency call handling system and method for a cellular telecommunications system. The emergency call handling system is provided with at least one subscriber terminal which upon failure to seize a voice connection to an emergency center for an emergency call, transfers data messages over the digital control channel to the emergency center advising it that the user of this one subscriber terminal has an emergency situation. Advantage is found with the present invention in that in times of radio voice channel and/or network traffic congestion resulting in call set up failure, the information relating to a user emergency can be forwarded as data messages to the emergency center.
