EMERGENCY RADIO BEACON CAPABLE MOBILE COMMUNICATION SYSTEM, MOBILE TELEPHONE AND METHOD

摘要

A mobile communication system with a plurality of mobile telephones including an emergency radio beacon transmitting mobile telephone with an emergency radio beacon transmitter that is selectively activated in response to receipt from a coded emergency beacon activation signal from a beacon activating emergency center. The emergency beacon activating center determines whether an emergency call is from an emergency beacon capable mobile telephone based on receipt of the call on a dedicated emergency beacon capable trunk. Alternatively, the determination is based on a suffix number added to the emergency center number by an MSC/VLR switch prior to connection to the emergency center or is based on an emergency beacon capable indicating code added to the calling party's number. The beacon activation signal is one of a supplementary service data signal, a short message service signal and a control A-interface signal transmitted from a base radio transceiver which is coded for a particular telephone desire to be activated.
