Abstract: A remote transmission station (S1), 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 (E11, E21) 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 (S1) 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).

Abstract: 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.

Abstract: 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.

Abstract: A device (D) is dedicated to local routing of local traffic between optionally mobile communications terminals.
