A method implemented during a procedure for federating a first radio communication network with a second radio communication network, the first radio communication network comprising a first service orchestrator and the second radio communication network comprising a second service orchestrator, the method comprising the steps of: - aggregating, by means of a weight function, various items of information relating to the resources made available by the first radio communication network, respectively by the second radio communication network, at a current time, as well as their level of availability at said current time; - periodically calculating a first value of the weight function for the first radio communication network by the first service orchestrator; - periodically calculating a second value of the weight function for the second radio communication network by the second service orchestrator; and, when establishing a communication link between the first and second communication networks; - comparing the first and second values of the weight function with each other; and, - if the first value is greater than the second value, selecting the first service orchestrator as master service orchestrator of a federated network resulting from the federation of the first and second radio communication networks (100, 200), the second service orchestrator being placed under a supervision of the first service orchestrator as slave service orchestrator, and, if the second value is greater than the first value, selecting the second service orchestrator as the master service orchestrator of the federated network, the first service orchestrator being placed under supervision of the second service orchestrator as the slave service orchestrator, the method being characterised in that the first service orchestrator, respectively the second service orchestrator, stores a first hierarchical level, respectively a second hierarchical level, associated with to the first radio communication network, respectively to the second radio communication network, and in that the method furthermore comprises a step consisting in comparing the first and second hierarchical levels with one another, if they are identical, proceed to the steps consisting of comparing the values of the weight function, and if they are different, choose the service orchestrator with the highest hierarchical level as the master service orchestrator, and the other service orchestrator as the slave service orchestrator. - aggregating, by means of a weight function, various items of information relating to the resources made available by the first radio communication network, respectively by the second radio communication network, at a current time, as well as their level of availability at said current time; - periodically calculating a first value of the weight function for the first radio communication network by the first service orchestrator; - periodically calculating a second value of the weight function for the second radio communication network by the second service orchestrator; and, when establishing a communication link between the first and second communication networks; - comparing the first and second values of the weight function with each other; and, - if the first value is greater than the second value, selecting the first service orchestrator as master service orchestrator of a federated network resulting from the federation of the first and second radio communication networks (100, 200), the second service orchestrator being placed under a supervision of the first service orchestrator as slave service orchestrator, and, if the second value is greater than the first value, selecting the second service orchestrator as the master service orchestrator of the federated network, the first service orchestrator being placed under supervision of the second service orchestrator as the slave service orchestrator, the method being characterised in that the first service orchestrator, respectively the second service orchestrator, stores a first hierarchical level, respectively a second hierarchical level, associated with to the first radio communication network, respectively to the second radio communication network, and in that the method furthermore comprises a step consisting in comparing the first and second hierarchical levels with one another, if they are identical, proceed to the steps consisting of comparing the values of the weight function, and if they are different, choose the service orchestrator with the highest hierarchical level as the master service orchestrator, and the other service orchestrator as the slave service orchestrator.
