Abstract: Embodiments of methods and devices for classifying background noise contained in an audio signal are disclosed. In one embodiment, the device includes a module for extracting from the audio signal a background noise signal, termed the noise signal. Also included is a second that calculates a first parameter, termed the temporal indicator. The temporal indicator relates to the temporal evolution of the noise signal. The second module also calculates a second parameter, termed the frequency indicator. The frequency indicator relates to the frequency spectrum of the noise signal. Finally, the device includes a third module that classifies the background noise by selecting, as a function of the calculated values of the temporal indicator and of the frequency indicator, a class of background noise from among a predefined set of classes of background noise.

Abstract: A system is provided for updating the conditions under which a telecommunication device accesses services provided by a telecommunication network. The system includes a network access point through which the device accesses the network, and a database, wherein the system authenticates the device via the access point on the basis of authentication data transferred by the device as well as the database storing the profile associated with the authentication data. The access point controls the conditions under which the device accesses the network services once the device has been authenticated and on the basis of the device profile. The system generates a second authentication command for the device via the access point following an alteration of the profiled associated with the authentication data.

Abstract: A method and apparatus are provided for sending pulses from a sender device to a receiver device in a transmission channel. The pulses represent information symbols, with each of these pulses being associated with a time slot in a symbol time. The method includes a training step that is carried out before sending payload information and that includes sending a training sequence made up of two parts. A first part of the training sequence includes at least one pulse of energy that is greater than the energy of a pulse carrying payload information. There are a large number of time slots between the sending of the pulse and the sending of the next pulse. A second part of the training sequence includes a set of pulses known in advance and similar to the pulses used for carrying payload information, the energy of each of these pulses being equivalent to the energy of a pulse carrying payload information.

Abstract: A method of regulating traffic in a telecommunications network, including a first step of detecting a fault affecting a node or a link of the network. The second step below is then executed: the nodes located immediately upstream of said node/link that experienced the fault forward to the latter the registration requests sent by users of the network, to the extent that the throughput of said registration requests is below a predetermined clipping threshold associated with the registration requests; if the throughput of registration requests exceeds said clipping threshold, the excess requests are not forwarded to the node/link that experienced the fault, and the network sends to each user that sent a request refused in this way, a response prompting that user to observe a time-out period, said response specifying the recommended duration of said time-out period. Application in particular to IP networks using SIP signaling protocols.

Abstract: A method and apparatus are provided for determining a descriptor for a region of interest in an image. The method includes defining a grid of points for the region of interest. A respective zone of influence is associated with each point of the grid of points. A representative value is determined for each point of the grid of points as a function of its respective zone of influence. The representative value obtained for each point of the grid of points is compared with at least one reference value. The result of the comparison serves to define a descriptor for the region of interest.
