Abstract
A navigation assistance system provides navigational guidance to a user of a mobile appliance equipped with a radio transceiver. The user can specify a destination address either directly or categorically and select from any choices to resolve ambiguity. The user submits the selected destination to a fixed radio system such as a cellular telephony system which estimates the user position, determines the relative location of the destination and sends to the user appliance data which allows the display of approximate range and bearing to the destination. The mobile appliance can be equipped with a compass which can be electronic and which allows a user to be shown the direction of travel in order to reach the destination.

8. A mobile communications device which provides navigational assistance to a user, the device comprising:
-
a user interface module;
a data communication module which is capable of sending data to and receiving data from at least one fixed base station;
a navigation module which is operatively coupled to the user interface module, and the data communication module and which, when activated by the user;
receives from the user interface module destination data representing a destination;
causes the data communication module to communicate the destination data to the at least one fixed base station;
causes the data communication module to cooperate with the at least one fixed base station to determine a geographical location of the mobile communications device;
receives, from the data communication module, navigation data relative to the destination; and
causes the user interface module to represent the navigation data to the user. - View Dependent Claims (9, 10, 11, 12, 13, 14)

19. A base station for communications through a mobile communications device, the base station comprising:
-
a communications module which is capable of conducting communications with the mobile communications device;
a mobile device location module which is operatively coupled to the communications module and which is capable of determining a location of the mobile communications device; and
a mobile device navigation module which is operatively coupled to the communications module and the mobile device location module and which can assist navigation of the mobile communications module by;
causing the mobile device location module to determine a current location of the mobile communications device; and
causing the communications module to send navigation data representing the current location to the mobile communications device. - View Dependent Claims (20, 21, 22)
