Abstract: A method for estimating an occupancy level of a geographic area includes transmitting first signals to and receiving second signals from bodies within the geographic area by backscattering of the first signals. The bodies include first bodies permanently within the geographic area and second bodies temporarily within the geographic area. According to the first and second signals, a first map of the first bodies within the geographic area is generated. At a specified time period, following a reference time period, transmission of the first signals, reception of the radio signals and generation of the first map is repeated. According to the first and second signals, a second map of the bodies within the geographic area is generated. A number of the second bodies within the geographic area during the specified time period is determined as the occupancy level based on comparing the first map to the second map.

Abstract: It is disclosed a method and system for providing performance measurements in a packet-switched communication network, wherein a performance measurement application run by a user communication device monitors the performance of a packet flow which a user application run by the user communication device exchanges with the packet-switched communication network. This monitoring comprising providing values of a performance parameter relating to the packet flow. If, based on the performance parameter values provided by the performance measurement application, a failure condition affecting the packet flow is detected, a further monitoring of the performance of the packet flow is activated, by one or more measurement points located within the packet-switched communication network on the path of the packet flow. This further monitoring comprising providing values of a further performance parameter relating to the packet flow.

Abstract: In a method for managing access by a user device to multimedia services delivered by a communication system, the user device accesses the multimedia services through a Radio Access Technology (RAT). An information element sent to the user device from the communication system includes restriction information that indicates the types of RAT that the user device may use to access the multimedia services. The restriction information also includes the types of RAT that the user device cannot use to access the multimedia services. The information element also includes additional restriction information indicating the multimedia services that can be accessed by the user device, and the multimedia services that cannot be accessed by the user device. The additional restriction information is based on subscription information for the user device.

Abstract: It is disclosed a performance measurement application for a user communication device. The device runs at least one user application which exchanges at least one packet flow with a packet-switched communication network. When executed, the performance measurement application receives from an owner of the user communication device a request for performing a performance measurement. In response to such request, the performance measurement application activates a marking functionality comprising marking upstream packets of the packet flow to be measured and inducing the network node originating the downstream packets of the packet flow to be measured to mark them. The performance measurement application then provides performance parameter(s) relating to the marked upstream packets as transmitted and/or the marked downstream packets as received and, based on such parameter(s), provides a performance measurement. The measurement results are then shared with a measurement management server.

Abstract: A speaker recognition system for assessing the identity of a speaker through a speech signal based on speech uttered by said speaker is provided. The system includes a framing module that subdivides the speech signal over time into a set of frames, and a filtering module that analyzes the frames of the set to discard frames affected by noise and frames which do not comprise a speech, based on a spectral analysis of the frames. A feature extraction module extracts audio features from frames which have not been discarded, and a classification module processes the audio features extracted from the frames which have not been discarded for assessing the identity of the speaker.

Abstract: In a method for exchanging packets between first and second nodes of a packet-switched network, each packet comprises two fields settable to an idle value or measurement value. The first node transmits to the second node first packets having a filed set to measurement value. Upon reception of each first packet, the second node transmits back to the first node a second packet having a field set to measurement value. Upon reception of each second packet, the first node transmits to the second node a third packet having another field set to measurement value. A packet loss measurement is calculated as a difference between the number of first packets and the number of third packets.
