摘要： The invention concerns a method of communication between ground stations via satellites traveling around the Earth and forming part of a constellation overflying at least a major portion of the Earth, each ground station communicating during a particular time with a given satellite of the constellation. Two ground stations communicate via respective given satellites with which the stations are respectively communicating. To minimize the control means on board each satellite, the two satellites communicate via a predetermined communications link. A link of the above kind generally comprises one or more predetermined satellites.

摘要： A satellite for a satellite telecommunication system transmits signals at different powers on the downlink connection. The powers are chosen to limit the relative dynamic range of signals received on the downlink connection. The relative dynamic range of signals received on the downlink connection is advantageously less than 5 dB and preferably less than 2 dB. A digital processor circuit is used, together with an analog-digital converter, a circuit taking the fast Fourier transform of the converted signals, a circuit for monitoring the gain of the signals, a circuit for switching the signals to at least two amplifier subsystems each including an inverse fast Fourier transform circuit, a digital-analog converter and a power amplifier.

摘要： A device (D1) is dedicated to compression of streams of packets of data, for a communication equipment (E1) constituting a transmission end point in an Internet Protocol communication network (R), the packets of a stream each comprising, in particular, an IP header including a destination end point (E2) identifier, a session identifier and stream attributes, and said packets being intended to be transmitted after decomposition into cells. This compression device (D1) comprises processing means (MT1) responsible, if they receive a packet of a stream, i) for determining if the IP header of the packet can be compressed as a function of at least one chosen criterion, then ii) if so, for determining if the compression can lead to a reduction in the number of cells having to result from the decomposition of that packet, then iii) if so, for replacing in that packet at least its IP header by a compressed header comprising at least the session identifier and a compression identifier, after having transmitted beforehand to the destination end point (E2) of the received stream, in a partially compressed form, at least the IP header that has to be replaced.

摘要： A device (D) is dedicated to the allocation of shared resources on a return link between terminals (UE) and a communication management equipment (GW) of a communication network. It comprises processing means (MT) adapted, firstly, to determine a set of time/frequency plans as a function of at least one symbol rate capacity requested for a set of user terminals (UE) and a designation of a chosen set of frames, each defined by a chosen set of time slots of the same type, with a view to its transmission to each of the user terminals (UE) of the set, and, secondly, each time that a user terminal (UE) requests at least one capacity, to determine at least one suitable symbol rate taking account of the requested capacity and a corresponding time slot, called the optimum slot at the time of determination, from the time/frequency plans that have been determined, so as to optimize the allocation of the shared resources of the network.
