A remote transmission station (S), for a transmission installation (ID) in a radio communication network with a control unit (MS) for transmission stations with selected administration protocol, comprises controlled units (E, E) and is located in a part of the network separated from the control unit (MS) by a transmission connection (SAT) within the installation (ID). The station (S) further comprises control means (MG) for obtaining control information statuses relating to the controlled units (E) and processing means (MT) for i) storage of the states previously obtained by the control means (MG), ii) for comparison of the currently obtained states with the states previously stored and to determine each change in state and iii) to generate messages comprising each determined change in state for transmission thereof to the control unit (MS) by the connection (SAT).

Transmission of control information after optional selection and compression within a radio communication network

A point-to-multipoint or multipoint-to-multipoint communication network comprises at least one management center and remote traffic stations, between which radio links sharing resources allocated dynamically by the management center have been established. Each traffic station is tasked, whenever it needs additional resources to increase the useful traffic (UT) that it must transmit to the management center, with adding to the current useful traffic (UT) a first traffic (ST), known as smoothing traffic and representative of a selected margin, and a second traffic (AT), known as anticipated traffic and representative of an anticipated need for additional resources, in order to implicitly solicit the management center, then with determining whether additional resources were allocated by the management center, and, if additional resources were allocated, to increase the useful traffic (UT) by an amount corresponding as much as possible to the sum of the resources corresponding to the first traffic (ST) and allocated additional resources.

A device is disclosed for compressing data contained in input frames to be compressed constituted of stream frames defining portions of TRAU and signaling frames that have to be transmitted within a communication network and each of which is constituted of at least a header containing control data representative at least of the type of stream frame and where applicable payload data, certain types containing critical and/or non-critical data. The device analyzes each TRAU or signaling frame header contained in successively received input frames in order to determine its type and generates periodically compressed frames to be transmitted that are divided into first and second sections of variable size. The first section contains critical data compressed synchronously and the second section contains non-critical data compressed asynchronously.

The invention relates to a multiplexing device comprising a data compressor. The compressed data block leaving said compressor occupies a particular bandwidth. According to the invention, a bandwidth prediction unit calculates said bandwidth and deduces from it the available bandwidth for conveyance in a time space dedicated to Internet traffic. The invention also relates to a multiplexing device and a multiplexing/demultiplexing system. Particular application in a satellite telecommunication system.

A device (D) is dedicated to local routing of local traffic between optionally mobile communications terminals. The device (D), which is installed, for example, in a traffic router (R) connected via a transmission network portion to a radiocommunications network including a call switch (MSC), comprises processor means serving, in the event of first and second up traffic channels being set up between calling and called terminals (T, T) and the call switch (MSC), and first and second down traffic channels being set up between the call switch (MSC) and the calling and called terminals (T, T), to compare selected data conveyed in the first up traffic channel and in at least one down traffic channel set up after the first up traffic channel and in a selected time window, and then in the event of the comparison indicating that there is a correlation between the data conveyed in those channels, to order the traffic router (R) to route locally and directly the traffic from the first up channel to the second down channel and from the second up channel to the first down channel, without the traffic being sent to the call switch (MSC).

A method of broadcasting multimedia information items, a receiver of multimedia information items broadcast by that method, and a user interface for consulting the information items. The invention relates to a method of broadcasting multimedia information items in a network comprising a transmitter and at least one receiver of information, the method including determining a class to which each information item belongs, broadcasting ahead of time a descriptor relating to each information item, at each receiver, qualifying the potential interest of each information item on the basis of the descriptors received and as a function of a user profile defined in the receiver, broadcasting the information items associated with the descriptors previously broadcast, and, in each receiver, storing locally each information item as a function of the qualification based on the descriptors. The invention also relates to a receiver and a user interface for consulting broadcast information items.

A point-to-multipoint or multipoint-to-multipoint communications network includes remote traffic stations connected to a management center (CG) by radio links sharing resources. The management center (CG) includes a management module for determining a primary distribution of the resources, including assignment margins, between the radio links that it manages and previously set up between the traffic stations, as a function of first information data representing rates of occupancy per traffic type of the resources previously assigned to the radio links. Each traffic station can then determine a secondary distribution between its traffic types of the resources assigned to its radio link as a result of the primary distribution, taking account of its own rates of occupancy per traffic type.

In a secure method of deciding on a communication channel in a data decompression device, the compressor detects channels that vary from one frame to another, which are referred to as 'active' channels. It transmits active and passive channels in a data block which also contains a state code locating the active data in the starting frame in order to be able to reconstitute it in the decompressor. A reference pattern is transmitted incorporating the passive channels and a majority vote statistical analysis is applied to the states of the passive channels to decide on the state (0 or 1) of each bit constituting the pattern repeated by each passive channel. One particular application of the method is to a satellite telecommunication system.

An optimized method for the transmission of multimedia contents between a multimedia content transmitter and a multimedia content receiver in a mobile radio network transmitting a multimedia content description vector from the transmitter to the receiver, calculating a pertinence score of the content from the description vector and as a function of a user profile associated with a user of the receiver, and recovering, at the explicit request of the receiver, a block or blocks of the content not received by the receiver, with a priority depending on the pertinence score associated with the content to which the missing block(s) belong(s).

Optimized method of transmitting multimedia content

The invention concerns a method of transmitting non-dated digital data between a transmitter and a receiver in which the data can take at least two different paths between the transmitter and the receiver and handover from one path to another occurs during transmission. In the transmitter, packets intended for the second path are transmitted only after the last packet intended for the first path has been transmitted and in the transmitter and in the receiver packets on the first or second path are delayed in order for packets on the second path to arrive after packets on the first path. It is therefore not necessary to transmit signaling to differentiate the two paths at the receiver, which can include a single demodulator.
