Abstract: A mobile terminal configured for use in a mobile telecommunications network, the mobile terminal having an emergency notification facility and an identifier, the identifier usable by the network to recognize the mobile terminal as having the emergency notification facility and to change a system access priority for the terminal, where required. Preferably, the terminal also includes a sensing means configured to determine when the mobile terminal is in motion and/or associated with a vehicle and notify the network of such, in order to allow the network to change the system access priority based upon whether or not the terminal is in motion and/or associated with a vehicle. In this regard, mobile terminals with an emergency notification facility, particularly when moving or in a vehicle, are given a higher priority so that an emergency call can be quickly dispatched in the event of an accident.

Abstract: Through the use of an electro-acoustic transducer, a pressure wave of at least a predetermined intensity may be detected, such as one that may occur upon the activation of a vehicle's air bag. As the electro-acoustic transducer has a diaphragm that can be displaced under the influence of a pressure wave, the transducer can therefore be monitored for an event occurrence indicative of the pressure wave. This monitoring may involve passively monitoring an electrical connection of the transducer for an electrical signal of a predetermined level, such that the electrical signal is the event indicative of the pressure wave. The monitoring may involve passively monitoring a pressure switch, such that activation of the pressure switch is the event indicative of the pressure wave. Upon detection of the pressure wave event, a trigger signal may be output to an emergency notification device to instigate a communication regarding a possible emergency situation.
