A method for multiple use of a radio telephone, a radio telephone system, corresponding user identifying module and the presence detection device

摘要

The invention concerns a method and a system for enabling multiple use of a radiotelephone, also called station, included in a radio communication system. The invention is characterised in that the station can adopt at least the following two operating states, each defined by at least one distinct state parameter: a so-called 'mobile station' state, associated with a situation of geographical mobility of the station; and a so-called 'fixed station' state, associated with a situation of geographical rigidity of the station within a predetermined fixed site, narrowly delimited in space. Moreover, the inventive method comprises at least a step which consists in a switching over the station, automatically or by user control, based on the presence of the station in a fixed site. The method further consists in at least comparing the position of the station relative to a predetermined fixed site, so as to trigger or validate said at least one state switchover step, if the station effectively shifts from inside outwards of the predetermined fixed site, or inversely.
