Abstract
A system and method for remote maintenance of user units allows efficient diagnosis of failures in a reduced time. Each user unit transmits to a management server, via a network, state data related to hardware and software parameters associated to an operating mode of the user unit. The method includes: storing state data in a user unit memory, monitoring state data stored in the memory, and detecting at least one datum of a state indicating an operational failure of the user unit. When a failure is detected, state data corresponding to current states of the user unit at the moment of the failure and state data corresponding to states stored during a predetermined period before the failure are extracted and transmitted to the management server which determines a statistic correlation coefficient between the values of each state of a user unit and the values of states of other user units.
