Abstract:
1. In a cellular network, a mobile radio set for the transmission of at least one of speech and data, said mobile radio set comprising: a first storage unit operable to store a first set of channels associated with the cellular network; a first acquisition unit operable, for each channel of the first set of channels, to determine a variable prior to a switching OFF of said mobile radio set and after a subsequent switching ON of said mobile radio set, each variable being dependent on a distance between said mobile radio set and a base station corresponding to a channel associated with the variable; a second storage unit operable, for each channel of the first set of channels, to store each variable determined prior to the switching OFF of said mobile radio set; and an evaluation unit operable, for each channel of the first set of channels upon the subsequent switching ON of said mobile radio set, to determine a deviation between a first corresponding variable stored in the second storage unit prior to the switching OFF of said mobile radio set and a second corresponding variable determined by said first acquisition unit after the subsequent switching ON of said mobile radio set, said evaluation unit further operable to decide whether said mobile radio set moved between the switching OFF of said mobile radio set and the subsequent switching ON of said mobile radio set as a function of each deviation.
