Claim 13:
14. A user terminal configured to enter or re-enter into a satellite communication network comprising at least one non-geostationary satellite, communications of the satellite communication network being organized according to a beam-hopping mechanism wherein hop frames define antenna beam configurations of the at least one non- geostationary satellite, resources of the hop frame being reserved for forming directional entry beams dedicated to entry or re-entry of user terminals into the satellite communication network, at least two of the directional entry beams having different directions of sight, the directional entry beams being configured so as to be able to the seen from the Earth with a constant elevation, the user terminal being configured to enter or re-enter into the satellite communication network by: orienting the elevation of its antenna beam to the elevation of the directional entry beam and by searching for the position of the satellite in azimuth alone, sending a request for entry or re-entry into the satellite communication network; and
wherein the directional entry beams are used for transmission, by the satellite, of information on the modalities of transmission of requests for entry or re-entry into the satellite communication network by user terminals, and for the transmission, by one or more user terminals, of requests for entry or re-entry into the satellite communication network.
