A method for configuring the input of at least one mobile terminal A in a satellite network comprising a satellite which transmits over several spots, the transmissions being organised in the form of frames and slots which are cut up into levels which are associated with times and frequencies of transmission, a set of modem hubs being installed in one or more hub stations, each modem hub being configured to exchange signals corresponding to one or more spots with the satellite and to carry out power measurements, the modem hubs being connected with each other, the modem hubs being associated with at least three frequency hopping laws among which one frequency hopping law which is referred to as the first frequency hopping law LS 1 which is specific to each modem hub and which gives the frequency associated with the traffic slot levels, and one frequency hopping law which is referred to as the second frequency hopping law LS 2 which gives the frequency associated with the slot levels of a channel which is common to all of the modem hubs, the method comprising at least the following steps: • during a first access, synchronising the terminal A to the first frequency hopping law LS 1, identifying the frame and the slots which use the second frequency hopping law LS 2, then synchronising the terminal to this second frequency hopping law LS 2 whilst listening to the slots, • the terminal A uses one or more slots of the common channel to transmit an identification signal, said identification signal is heard by all the modem hubs which are configured to receive on the slots according to this second frequency hopping law, • the terminal A begins listening on said common channel to be notified of the radio resource and the frequency hopping law to be used by a modem hub which is determined to be the connection modem hub for the terminal, the determination of the connection modem hub being carried out in the following manner: • each modem hub measures the power level of the identification signal transmitted by the terminal A, • each modem hub communicates to the other modem hubs the measured power value of the identification signal, ∘ the modem hub having the maximum power value is considered to be the connection modem hub for the terminal A. • during a first access, synchronising the terminal A to the first frequency hopping law LS 1, identifying the frame and the slots which use the second frequency hopping law LS 2, then synchronising the terminal to this second frequency hopping law LS 2 whilst listening to the slots, • the terminal A uses one or more slots of the common channel to transmit an identification signal, said identification signal is heard by all the modem hubs which are configured to receive on the slots according to this second frequency hopping law, • the terminal A begins listening on said common channel to be notified of the radio resource and the frequency hopping law to be used by a modem hub which is determined to be the connection modem hub for the terminal, the determination of the connection modem hub being carried out in the following manner: • each modem hub measures the power level of the identification signal transmitted by the terminal A, • each modem hub communicates to the other modem hubs the measured power value of the identification signal, ∘ the modem hub having the maximum power value is considered to be the connection modem hub for the terminal A. • each modem hub measures the power level of the identification signal transmitted by the terminal A, • each modem hub communicates to the other modem hubs the measured power value of the identification signal, ∘ the modem hub having the maximum power value is considered to be the connection modem hub for the terminal A. ∘ the modem hub having the maximum power value is considered to be the connection modem hub for the terminal A.
