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 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.

Layer 2 compression/decompression for mixed synchronous/asynchronous transmission of data frames within a communication network

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).

Device for locally routing local traffic within a radiocommunications network

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.
