First Claim
Patent Images
1. A mobile communications device enabled to make telephone calls, comprising:
- a controller for controlling the operation of the device;
a user input interface coupled to the controller;
a plurality of communications subsystems coupled to the controller for exchanging signals with respective wireless networks including a wireless local area network and a wireless wide area network (WAN); and
an electronic storage element coupled to the controller and having stored thereon a plurality of emergency numbers that are each associated with a country code;
wherein the controller is configured to, upon receiving through the user input interface a user input indicating that a user of the mobile communications device wants to initiate an emergency call;
determine if a wireless WAN is acquired through at least one of the communications subsystems at the time that the user input is received, and if so initiate a call from the mobile communications device to an emergency number selected from the plurality of emergency numbers in dependence on country code information received by the mobile communications device from the wireless WAN; and
if a wireless WAN is not acquired through at last one of the communications subsystems at the time that the user input is received, then determine if a WLAN is acquired through one of the communications subsystems and if so initiating a call from the mobile communications device to an emergency number selected from the plurality of emergency numbers in dependence on country code information received by the mobile communications device from the WLAN.

3. A mobile communications device enabled to make telephone calls, comprising:
-
a controller for controlling the operation of the device; a user input interface coupled to the controller; a plurality of communications subsystems coupled to the controller for exchanging signals with respective wireless networks; and an electronic storage element coupled to the controller and having stored thereon a plurality of geographic indicators and emergency numbers associated with the geographic indicators; wherein the geographic indicators each have a respective call order preference relative to the other geographic indicators, and the controller is configured for selecting an emergency number for use in a telephone call to an emergency service by;
selecting from the stored geographic indicators the geographic indicator having the highest call order preference at the time that the emergency call is initiated; and
determining from a plurality of emergency numbers stored in the storage element of the mobile communications device a selected emergency number in dependence on the selected geographic indicator. - View Dependent Claims (4, 5, 6, 7, 8)

9. A method of selecting an emergency number for use by a mobile communications device that is enabled for voice communications and has stored thereon a plurality of geographic indicators and emergency numbers associated with the geographic indicators, the geographic indicators each having a respective call order preference relative to the other geographic indicators, the method comprising:
-
detecting user input to initiate an emergency call; selecting from the stored geographic indicators the geographic indictor having the highest call order preference at the time that the user input is detected; and determining from a plurality of emergency numbers stored in the storage element of the mobile communications device a selected emergency number in dependence on the selected geographic indicator. - View Dependent Claims (10, 11, 12, 13, 14)
