Abstract: 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.

Abstract: The invention relates to a compressor of data from data frames. According to the invention, the compressor detects “active” elements that vary from one frame to another and transmits only the “active” elements in a data block. This block also contains a state code locating this “active” data in the original frame, in order to be able to reconstitute it. The invention also relates to a data decompressor, a data block containing a data group compressed in accordance with the invention, and a bandwidth resource management method. Particular application in a satellite telecommunication system.
