METHOD OF MULTIPLE USE OF A RADIOTELEPHONE, AND SYSTEM, RADIOTELEPHONE, SUBSCRIBER IDENTIFICATION MODULE, AND CORRESPONDING PRESENCE DETECTION DEVICE

摘要

The invention relates to a method and a system for multiple use of a radiotelephone, also called station, of the type included in a radiocommunication system. According to the invention, the station can take 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 geographical mobility situation of the station; and a so-called "fixed station" state, associated with a geographical fixity situation of the station within a predetermined fixed location, narrowly defined spatially. In addition, the method according to the invention comprises at least one status changeover step of the station, automatically and / or on command of a user, depending on the presence of the station in the fixed location. The method also comprises at least one step of comparing the position of the station with respect to the predetermined fixed location, so as to trigger or validate said at least one state-switching step, if the station is actually going from the inside towards outside the predetermined fixed place, or vice versa. / P
