Abstract: A resource reservation method with guaranteed service in terms of minimum bit rate and maximum access time at radio network nodes using time slots each associated with an individual bit rate for sending and transmitting data. A node includes a protocol layer that sends a reservation request to a MAC layer. The source node introduces into the format of the Path and Resv messages of the RSVP protocol fields corresponding to the maximum duration of the time slot observed on the current path in the Adspec reservation request of the Path message, the number of radio nodes crossed in the object of the Path message, and the maximum waiting time for the time slot in the Rspec object of the Resv message corresponding to the response to the reservation request. The MAC layer reserves the number of time slots needed to satisfy the service guarantee recorded in the reservation request.

Abstract: The invention relates to a method and system for controlling and analyzing cellular radio communications exchanged between mobile terminals and base stations BTS. The invention is characterized in that a dummy mobile terminals and base stations BTS. The invention is comprising a dummy mobile telephone network RRTM_F comprising a dummy base station BTS_F and a dummy mobile terminal MS_F are inserted into the real network RRTM_R, said dummy network being responsible for the decoding and transparent synchronous relaying of messages exchanged between the real network and the real mobile as well as real mobile access control from the real network or the dummy network.

Abstract: Method of locating one or more transmitters on the basis of an array of sensors moving with respect to the transmitters comprising at least the following steps: determining the direction vectors âk corresponding to the response of the array of sensors to a source with incidence (?, ?) as a function of the incidence parameters ?, ?, and of the parameter p related to the distortion of the phases on the sensors, transforming this vector âk so as to eliminate the unknown parameter p, into a vector ?km, ??km, using the transformed vector to obtain the position of the transmitter using a maximized locating criterion.
