Abstract: A method for updating a predictive model of a variable representing the operation of a mobile terminal connected to a communication network by packets is described. A first predictive model is configured to estimate a value of the variable as a function of the value of predictors, linked to the variable by a common operating context. The method can be implemented by the mobile terminal and can include generating a feed message, comprising at least the measured value and the values of the predictors, if 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 can further include transmitting the at least one feed message generated, to an update server connected to the network, receiving an update message, comprising a second predictive model updated on the basis of at least the feed message, coming from the update server, and replacing the first predictive model with the second predictive model.

Abstract: This messaging system is for use in a peer to peer network including at least one depositary peer (PX, PR) adapted to store a message in one or more portions and to send a message notifying the completion of the storage of that portion to at least one superpeer (SPX) of the peer (PX) of the depositor (X) of the message (M). This superpeer (SPX) is adapted to send a notice of reception of the message to a peer (PY) of the addressee (Y) of that message, that notice including a list of the depositary peers (PX, PR) and an identifier of each of the portions of said message stored by each of the depositaries (PX, PR).

Abstract: A method of allocating a plurality of subbands to a plurality of streams of a multichannel link in a multicarrier modulation communications system, each stream being successively defined in a communications frame of said multichannel link by a number Mj of bits to be transmitted and a noise margin ?j. Each subband is associated with a normalized signal-to-noise ratio on the multichannel link. The subbands are classified in a specific order of the normalized signal-to-noise ratios. An energy Ei per subband is determined by a binary allocation algorithm. For each stream taken in the order of said frame, a number Nj of consecutive subbands taken in the order of normalized signal-to-noise ratios is allocated so that the sum of the numbers nij of bits in each subband allocated to each stream is equal to Mj where: M j = ? i = 1 N j ? n ij and nij=log2(1+El·(SNR0)i/?J).

Abstract: A method of allocating a plurality of subbands (SBi) to a plurality of streams (FLj) of a multichannel link in a multicarrier modulation communications system, each stream (FLj) being successively defined in a communications frame of said multichannel link by a number Mj of bits to be transmitted and a noise margin ?j. Each subband (SBi) is associated with a normalized signal-to-noise ratio (SNR0)i on the multichannel link. The subbands (SBi) are classified in a specific order of the normalized signal-to-noise ratios (SNR0)1. An energy Ei per subband (SBi) is determined by a binary allocation algorithm. For each stream (FLj) taken in the order of said frame, a number Nj of consecutive subbands (SBi) taken in the order of normalized signal-to-noise ratios is allocated so that the sum of the numbers nij of bits in each subband (SBi) allocated to each stream (FLj) is equal to Mj where: M j = ? i = 1 N j ? n ij the number nij of bits being defined by: nij=log2(1+E1·(SNR0)i/?j).
