| 6. A method for position information using a satellite assisted position measuring device with a power drawing measurement
mode, a power saving idle mode and a mobile radio network assisted communication device for sending the position via a cellular
mobile radio network, comprising the following steps in any order:
(a) ascertaining local reception field strength or local cell identifier of a mobile radio network using a communication device
and, if the reception field strength changes at least by a prescribed threshold value or the cell identifier changes, the
position measuring device is switched to the measurement mode;
(b) ascertaining a present position of the apparatus using the position measuring device and, if the position remains the
same over a prescribed period, the position measuring device is switched to the idle mode.
