Abstract: A method is disclosed of tracing a path to be taken by a mobile terminal receiving electromagnetic waves transmitted by transmitter stations, the path being traced by an operating platform, which method comprises a learning phase comprising a taking of the path during which, exclusively on the path, a periodic routine learning recording of successive groups of samples is made in a route memory, a sample comprising at least one value of each of the frequencies received at each of the periodic recordings, and a receive level associated with that frequency, and a comparison of the received levels between a group of pn samples recorded during a sampling of rank n and one recorded preceding group of rank lower than n, a comparison criterion discriminating between remarkable groups and ordinary groups.

Abstract: The invention relates to a method for monitoring a person carrying a cellular telephone through a communication network wherein: An expected path for the monitored person is determined by identifying a sequence of successive places or checkpoints, and A real path followed by the monitored person is detected and compared with the expected path, both in space and in sequence, so that An alert is sent to at least one individual, called alertee, through the communication network when the real path differs from the expected path in place, sequence or in both place and sequence. The invention also relates to a cellular telephone and a server implementing such method.
