Abstract

A user of a mobile terminal is enabled to call emergency services in a wireless telecommunications network, whether or not the user is in a foreign country. If the user signals for emergency help by sending an emergency call code to the base station, the user is connected to an emergency center corresponding to the user'"'"'s base station. The user may also be provided with an emergency services display. Further, the user may be connected to a specific type of emergency center corresponding to the user'"'"'s base station, if the user signals for the specific type of emergency center by sending a service category to the base station. These emergency signals sent from the mobile terminal to the base station are location-independent, and therefore work well at an international level.
