A system, for a movable terminal, for assisting in the selection of a radiocommunication infrastructure (I i) among a plurality of available radiocommunication infrastructures, with a view to establish a communication link between the movable terminal and a selected infrastructure allowing an application (A k) executed on the movable terminal to access a remote resource (S k), the system implemented on the movable terminal including: - a database including a plurality of mappings (C ik), each mapping being associated with an infrastructure of said plurality of infrastructures and with a type of application, a mapping giving, at each point of a geographical area, a local value of a quantity relating to a quality of experience associated with an execution of an application of said type of application accessing said remote resource through said infrastructure; and a plurality of trajectories capable of being followed by the movable terminal through said geographical area; - a selection means allowing a user of the terminal to choose a trajectory (t n) among the plurality of trajectories stored in the database; - a localization means suitable for generating a current position of the movable terminal; - a module for determining alternative trajectories configured to calculate one or more trajectories alternative to the trajectory (t n) initially selected by the user; - a correlation means suitable for, from the current position and the selected trajectory, and for each mapping associated with the type of application corresponding to said application executed on the movable terminal, determining a correlation coefficient; the correlation coefficient calculated by the correlation means resulting from the integration, along the selected trajectory, of a function of the quality of local experience indicated on the considered mapping; said correlation means being configured to determine in the same way by using the adapted mappings a correlation coefficient for each determined alternative trajectory; - a selection means suitable for, on the basis of the calculated correlation coefficients, selecting a pair consisting of an infrastructure among said plurality of infrastructures and a trajectory among said alternative trajectories. - a database including a plurality of mappings (C ik), each mapping being associated with an infrastructure of said plurality of infrastructures and with a type of application, a mapping giving, at each point of a geographical area, a local value of a quantity relating to a quality of experience associated with an execution of an application of said type of application accessing said remote resource through said infrastructure; and a plurality of trajectories capable of being followed by the movable terminal through said geographical area; - a selection means allowing a user of the terminal to choose a trajectory (t n) among the plurality of trajectories stored in the database; - a localization means suitable for generating a current position of the movable terminal; - a module for determining alternative trajectories configured to calculate one or more trajectories alternative to the trajectory (t n) initially selected by the user; - a correlation means suitable for, from the current position and the selected trajectory, and for each mapping associated with the type of application corresponding to said application executed on the movable terminal, determining a correlation coefficient; the correlation coefficient calculated by the correlation means resulting from the integration, along the selected trajectory, of a function of the quality of local experience indicated on the considered mapping; said correlation means being configured to determine in the same way by using the adapted mappings a correlation coefficient for each determined alternative trajectory; - a selection means suitable for, on the basis of the calculated correlation coefficients, selecting a pair consisting of an infrastructure among said plurality of infrastructures and a trajectory among said alternative trajectories.
