A mobile structure of a radio-communication system, said mobile structure comprising: - a base station which is adapted to establish cellular communication links with the mobile communication terminals (106a, 106b) through a specific radio interface (LTE-Uu), in a specific frequency spectrum; - a mounted radio scanner having means for measuring a radiofrequency signal transmitted in the specific frequency spectrum, by at least one third-party structure located in the immediate environment of said mobile structure, characterized in that said scanner is configured to determine, based on physical properties of the measured radiofrequency signal, information associated with the use of the specific frequency spectrum for radio transmissions transmitted by said third-party structure and that can be used to decide whether or not to initiate and, if necessary, to manage the establishment of a backhaul data transport link between the mobile structure and the third-party structure, the mounted radio scanner being configured to transmit to a control entity of the mobile structure, information associated with the use of the determined frequency spectrum, for radio transmissions, transmitted by the third-party structure, the control entity of the mobile structure being configured to identify free radio resources, such as a new frequency spectrum with a width smaller than the specific frequency spectrum, which are not used by the third-party structure, the control entity of the mobile structure being further configured to allocate a portion of the free radio resources to the establishment of a backhaul data transport link connecting the mobile structure to the third-party structure. - a base station which is adapted to establish cellular communication links with the mobile communication terminals (106a, 106b) through a specific radio interface (LTE-Uu), in a specific frequency spectrum; - a mounted radio scanner having means for measuring a radiofrequency signal transmitted in the specific frequency spectrum, by at least one third-party structure located in the immediate environment of said mobile structure, characterized in that said scanner is configured to determine, based on physical properties of the measured radiofrequency signal, information associated with the use of the specific frequency spectrum for radio transmissions transmitted by said third-party structure and that can be used to decide whether or not to initiate and, if necessary, to manage the establishment of a backhaul data transport link between the mobile structure and the third-party structure, the mounted radio scanner being configured to transmit to a control entity of the mobile structure, information associated with the use of the determined frequency spectrum, for radio transmissions, transmitted by the third-party structure, the control entity of the mobile structure being configured to identify free radio resources, such as a new frequency spectrum with a width smaller than the specific frequency spectrum, which are not used by the third-party structure, the control entity of the mobile structure being further configured to allocate a portion of the free radio resources to the establishment of a backhaul data transport link connecting the mobile structure to the third-party structure.
