1. A method to mask static cell identifiers (cell IDs) or static location area codes (LAC or RAC) of a mobile network, comprising generating, via a mobile terminal, all or part of dynamic cell identifiers (cell ID_d) or dynamic location area codes (LAC_d or RAC_d), by means of a masking module integrated in equipment belonging to the architecture of the network under consideration, from static cell identifiers (cell ID) or from static location area codes (LAC or RAC) so as to make their solving into geographical coordinates scarcely reliable or impossible by any outside actor or service other than services authenticated by the operator;

  • andeither generating, at the signalling channel, the static cell identifiers (cell ID) or static location area codes (LAC or RAC) from the dynamic cell identifiers (cell ID_d) or dynamic location area codes (LAC_d or RAC_d), sent up through the network by the mobile terminal to the masking module, so as to ensure translation of the static cell identifier (cell ID) or static location area code (LAC or RAC) intended for the other equipment of the network under consideration, by means of said masking module;

    or updating, globally or partially the other equipment of the network under consideration and the operator'"'"'s information system by means of said masking module.
