1. A mobile device, comprising:
- a positioning unit adapted to determine a position of the device; and
a movement sensor adapted to detect a movement of the device, wherein the positioning unit is further adapted to use a last determined position of the device as a new position thereof if no substantial movement of the device has been detected by the sensor since the last position was determined, and wherein the positioning unit is still further adapted to determine a new position of the device if a movement of the device has been detected by the sensor since the last position was determined.

Abstract
The invention relates to a mobile device that includes a positioning unit that is adapted to determine the position of the device, and a movement sensor that is adapted to detect a movement of the device. When the positioning unit is requested to determine the position, the device is adapted to use the last position as new position if no movement of the device has been detected by the sensor since the last position was determined. A new position is ascertained if a movement of the device has been detected by the sensor since the last position was determined.

8. A method of determining a position of a mobile device comprising:
-
requesting a positioning unit to determine a position of the mobile device;
determining whether the mobile device has moved substantially from a last position where a last position determination was made using a movement sensor;
using the last position determination as a new position determination if the mobile device has not moved substantially; and
determining the new position of the mobile device using the positioning unit if the mobile device has moved substantially. - View Dependent Claims (9, 10, 11)

12. A mobile device, comprising:
-
a positioning unit configured to determine a position of the mobile device; and
a movement sensor configured to provide data to the positioning unit reflecting a movement of the mobile device, wherein the positioning unit is further configured to determine a most recent previous position of the mobile device as a present position of the mobile device if the movement sensor data reflects no substantial movement of the mobile device since the most recent previous position was determined. - View Dependent Claims (13, 14, 15, 16, 17)
