The present invention relates to a radio access arrangement for operating a radio cell (C), and comprising at least one wireless transceiver () configured to set up and operate radio communication channels with mobile devices. In accordance with an embodiment of the invention, the radio access arrangement further comprises speed determination logic () configured to characterize a particular mobile device () as belonging to a high-speed or lower-speed category (HS; LS) according to speed information of the particular mobile device, and a radio resource controller () configured to assign a particular radio communication channel, for communication with the particular mobile device, within a first or second disjoint radio resource partition of the radio cell (B_DLB_ULB_DLB_UL) if the particular mobile device is characterized as belonging to the lower-speed or high-speed category. The radio access arrangement further comprises a transmit power controller () configured to control a transmit power used for communication over the particular radio communication channel as being lower than a first or second substantially higher maximum transmit power level (PTXMAX_DLPTXMAX_ULPTAX_MAX_DLPTXMAX_UL) if the particular radio communication channel is assigned within the first or second radio resource partition respectively, thereby yielding a long-reach radio coverage area () for high-speed mobile devices and a shorter-reach radio coverage area () for lower-speed mobile devices. The present invention also relates to a method for operating a radio cell, and to a method for configuring radio resources of radio cells.

An interleaver (ER) is dedicated to interleaving of interleaving units representing a selected number of services grouped into periodic frames within a long period time interleaving radio communication network. The said interleaver (ER) comprises processing means (MT) responsible for decomposing each frame into a chosen number of group(s) of service of constant respective durations, and then for distributing the interleaving units of each group into so-called spreading time intervals of constant respective durations spaced apart within a time interleaving period according to a period equal to the period of the frames.

Interleaver and device for selecting services, for a radiocommunication network with long time interleaving at the level of the physical layer

At least one example embodiment discloses a system including a plurality of base stations. The system further includes a proxy server configured to generate a request for loading information from at least one of the plurality of base stations and receive the loading information from the at least one of the plurality of base stations, the request being a base station to base station interface message.

Methods and systems for obtaining load information in networks

Within a radio communication network infrastructure transmitting data organized into a sequence of symbols to a receiving device over a plurality of radio links, data to be transmitted is encoded according to an error correction coding scheme in order to produce a set of systematic symbols and a set of corresponding redundancy symbols; the systematic symbols and a first subset of the corresponding redundancy symbols are transmitted, over a first radio link among said plurality of radio links, in broadcast mode, and a second subset of the corresponding redundancy symbols, distinct from the first one, is transmitted over a second radio link among said plurality of radio links.

Method for transmitting data from an infrastructure of a radio communication network to user devices, and devices for implementing the method

IP encapsulation equipment encapsulates, into bursts, IP packets representing sets of multimedia data delivered by at least one multimedia content server. The bursts are accompanied beforehand by information data at least partly defining the set of data that is integrated into those IP packets and/or the content of which that set of data forms part, with a view to the broadcasting thereof to receiver equipments via a communication network. The information data added to the received IP packets is analyzed to instruct the encapsulation means to encapsulate at least some of those IP packets in selected positions in the bursts as a function of the corresponding information data. In this manner, all the IP packets including, the data of a set, are encapsulated in a single burst.

Transmission of IP packets of contents by addition to those IP packets of information data relating to the contents

Within a user device to which a radio communication network infrastructure transmits data carried by a sequence of frames broadcast to the user device, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, a number of consecutive lost frames is compared to a threshold dependent on the number B of previous frames with which said redundancy information is associated and encoding parameters that generate said redundancy information, and a request to retransmit at least one of the consecutive lost frames is sent to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold.

A satellite telecommunication system includes a plurality of user stations and at least one satellite. A resource manager for the satellite telecommunication system includes a congestion controller that assigns resources to uplinks, a demand assignment device that assigns resources to uplinks, and, for each satellite, a central entity that includes a subsystem of the congestion controller adapted to receive requests sent by user stations using the satellite, each request expressing the bit rate necessary for a group of connections supported by a user station and by the same downlink of the satellite, and to determine the bit rate authorized for the group of connections. It further includes, for each satellite, a subsystem of the demand assignment device adapted to allocate resources to an uplink, at each user station, as a function of the bit rates authorized by the congestion controller subsystem and globally for all connections supported by the user station.

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.
