Abstract: A tool for aiding utilization of communicating equipment includes a resources manager associated with a data structure where an equipment identifier is connected with dated values of utilizable global functional capability of the resource, and dated values of temporarily allocated functional capability. A scheduling tool evaluates an acceptance condition by comparing dates which pertain to a dated functional capability and to the dated series of functional capability maintained in connection with one or more resource identifiers. A resources allocator receives an identified request for temporary reservation of functional capabilities, including a dated suite of functional data, it responds thereto by calling a resources selector for each functional data item of the request, the scheduling tool for some at least of the identifiers of the subset returned by the resources selector; and by returning a set of resource identifiers as response to the reservation request.
