摘要

:. The present invention concerns a process and a system for producing, when a standard portable mobile telephone is called, an acoustic signal of power comparable to that of the ring of a domestic telephone instrument. The process includes the stages: of autonomous detection (1) by the mobile telephone, directly or indirectly, of the call from the calling station and of generation of a detection signal, - of triggering (2,3), by means of said detection signal, the emission of an acoustic signal of power (4) comparable to that of the ring of a domestic telephone instrument. Thus, the user of the standard mobile telephone is alerted to the incoming call even if he/she happens to be some distance away from the standard mobile telephone. No. of Pages : 25 No. of Claims : 16
