摘要： A multiple frequency time division multiple access digital telecommunication system, in particular a transparent satellite telecommunication system, includes terminals and a base station. Calls can be effected in star mode, via the base station, or in meshed mode, directly between the terminals, which are divided into two groups. The frequency band allocated to the system is divided into two parts, comprising a first part for sending by the first group and a second part for sending by the second group. Each part of the frequency band is divided into two sub-bands. The central sub-bands are used for meshed sending, the end sub-bands are used for star sending, and the two central sub-bands are also used for meshed reception by both groups of terminals.

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 method of allocating communication resources to terminals in an MF-TDMA telecommunication system is provided, in which digital data is transmitted in selected time intervals on each of a plurality of carriers. The resources for each terminal are allocated to frames grouped into superframes. The pattern of resources (time intervals and carriers) allocated to the terminal for the transmission of real-time data in each frame of a given rank in a superframe remains the same throughout the various superframes of the call relating to the real time data. Accordingly, the transmission of real time data is virtually free of jitter.

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.
