Title: METHOD AND DEVICE FOR UPDATING A PREDICTIVE MODEL OF A VARIABLE RELATING TO A MOBILE TERMINAL
Abstract:
The invention concerns a method for updating a predictive model of a variable representing the operation of a mobile terminal (T1) connected to a communication network by packets, a first predictive model (Model1) being capable of estimating a value of the variable, called the estimated value, as a function of the value of parameters, called predictors, linked to the variable by a common operating context, the method being implemented by the mobile terminal and comprising at least one cycle of the following steps: · measuring (E03) the variable, producing a measured value, · obtaining (E04) values of the predictors, · estimating (E05) the estimated value using the first predictive model depending on the values of the predictors, · generating (E07) a feed message, comprising at least the measured value and the values of the predictors, if (E06) the difference between the measured value and the estimated value is greater than or equal to a determined threshold, called the feed threshold, the method further comprising the following steps: · transmitting (E08) the at least one feed message (Msg Alim1) generated, to an update server (BE) connected to the network, · receiving (E13) an update message (MsgActu1), comprising a second predictive model (Model2) updated on the basis of at least the feed message, coming from the update server, · replacing (E14) the first predictive model with the second predictive model.
