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.

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).
