Abstract
The invention relates to a mobile radio set (M) for a cellular network. In order to enable a more reliable determination as to whether a mobile radio set has been moved between switching off and subsequent switching on, the following elements are provided: a first storage section (S1) for storing all relevant channels, acquisition means (E1) for measuring, for the channels stored in the first storage means (S1) prior to the switching off and after the switching on of the mobile radio set (M), a variable which is dependent on the distance between the mobile radio set (M) and the base stations that make a channel available, a second storage section (S2) for storing the variables measured before the switching off, and evaluation means (A) for determining a value characterizing the deviation between the variables stored in the second storage section (S2) and the variables measured after the switching on. Comparison of this value with a predetermined value then enables the decision that movement has taken place. The invention also relates to a method of determining a movement of a mobile radio set.
