Method for re-allocating resources in an integrated satellite-terrestrial network if an abnormal situation occurs in an area covered by the integrated satellite-terrestrial network, the integrated satellite-terrestrial network comprising a terrestrial cellular component composed of cells, a satellite component and a network controller communicating with both the terrestrial and the satellite components, the resources allocated to the satellite component being split into several sub-portions of resources used by a set of beams generated by a satellite of the satellite component for a multi-beam transmission at the terrestrial surface, wherein in each beam using one sub-portion of resources, the cells in said beam use different resources from the sub-portion of resources used by said beam, characterized in that the resources of the integrated satellite-terrestrial network are further comprising resources that may be re-allocated when an abnormal situation occurs in the area covered by the integrated satellite-terrestrial network and in that the method comprises the steps, executed by a network controller capable of communicating with both the terrestrial and the satellite components of the integrated -satellite-terrestrial network, of: - monitoring reports in the integrated satellite-terrestrial network, - checking if an abnormal situation occurs according to the content of reports by checking if an increased traffic demand on the terrestrial cellular component occurs in a geographical region and/or by checking if an increased traffic demand on the satellite component occurs in the geographical region and/or by checking if cells of a geographical region fail to provide reports and/or by checking if interference level increases on cells surrounding the geographical region and if an abnormal situation occurs: - identifying a region wherein the abnormal situation occurs, - computing (S503, S504) a center of a steerable beam situated in the identified region, - transferring to the satellite component a command in order to apply the steerable beam pointing towards the computed center, the steerable beam using at most all the resources that may be re-allocated, - transferring to the component of the integrated satellite-terrestrial network which was using, before the abnormal situation occurs, the at most all resources that may be re-allocated a command to stop using the at most all resources that may be re-allocated at least in the area covered by the steerable beam. - monitoring reports in the integrated satellite-terrestrial network, - checking if an abnormal situation occurs according to the content of reports by checking if an increased traffic demand on the terrestrial cellular component occurs in a geographical region and/or by checking if an increased traffic demand on the satellite component occurs in the geographical region and/or by checking if cells of a geographical region fail to provide reports and/or by checking if interference level increases on cells surrounding the geographical region and if an abnormal situation occurs: - identifying a region wherein the abnormal situation occurs, - computing (S503, S504) a center of a steerable beam situated in the identified region, - transferring to the satellite component a command in order to apply the steerable beam pointing towards the computed center, the steerable beam using at most all the resources that may be re-allocated, - transferring to the component of the integrated satellite-terrestrial network which was using, before the abnormal situation occurs, the at most all resources that may be re-allocated a command to stop using the at most all resources that may be re-allocated at least in the area covered by the steerable beam.
