A method for sharing spectrum in a communication network, comprising at least two systems working in frequency ranges that can overlap at least partially and in one and the same geographic area, comprises at least the following steps: affiliating the first and second systems with a server; determining whether there is a constrained system and, if there is, assigning said constrained system a first spectral band, for a given geographic area; performing this assignment for all the geographic areas covered by the two systems; and identifying the non-constrained systems and, by applying sub-band priority and management rules, assigning, for each of the non-constrained systems and each defined geographic area, a spectral band for each of the systems, and in the case where it is impossible to find a spectral sub-band, generating an alarm.
