A method in accordance with the invention applies to an access network or a satellite infrastructure network supporting sub-networks grouping different terminal stations in which each packet is associated with an addressing header and in which each terminal station is associated with a satellite terminal or with a ground station that is located in the coverage of a particular spot of a particular satellite. The addressing header of each packet further contains a 'label' field containing an identifier characteristic of a sub-network to which said terminal station and the spot in which the satellite terminal or the ground station with which it is associated is located belongs.

Addressing method for use in an access network or a satellite infrastructure network that can support data transfer in non-connected mode

In a telecommunication network, the power of a first signal transmitted via a satellite by a first station to be received in the form of a second signal by a second station is regulated. At a given time, a value representative of a signal-to-noise ratio of the second signal is predicted for a later time, and, at an intermediate time, the power of the first signal is regulated in the first station as a function of the predicted value. The intermediate time precedes the later time by a time period substantially equal to the propagation time between the first and second stations.

Method of regulating the power of a signal transmitted by a first

The invention provides a method of regulating the power of transmission between first and second stations in a multiple satellite visibility satellite telecommunication network. The method comprises the following cyclic steps: regulation, for each of said N channels, of an isolated transmit power level command signal such that when it commands the power at which the first station transmits the first isolated signal in each channel the quality level of the corresponding isolated second signal received by the second station is equal to a reference quality level, and regulation, for all of the N channels, of N combined transmit power level command signals such that when they command the levels at which the first station respectively transmits the N first combined signals on the N channels the quality level of the global signal received formed from the N combined second signals is equal to the reference quality level. Depending on whether the isolated command signal having the minimal level is such that this minimal level is less than or greater than a maximal tolerated isolated command level, the minimal level isolated command signal is selected to command the power with which the first station transmits a call signal in the corresponding channel, or the N combined command signals are selected to command the power with which the first station transmits respective combined call signals on the N channels.
