Process for making decisions by a so-called decider processing unit, by propagation of a proposition in a mobile telephone network comprising processing units, each processing unit being provided with decision intelligence, characterised in that: a) the decider determines a proposition upon reception of a request to allocate a PCI number to an eNodeB of the mobile telephone network, the proposition being a PCI number, Physical Cell Identity, that the decider wants to present in response to said request, the decision to be made being the confirmation or the denial of the PCI number to be presented in response to the request received, b) the decider selects a set of so-called voter processing units, to analyse the proposition and to present a response, this response comprising a confirmation of the proposition, a denial of the proposition or a "no opinion" response, c) the decider defines a percentage weighting for each voter or group of voters thus selected, d) the decider defines a confirmation threshold as a percentage from which the proposition is considered as confirmed, e) the decider defines a denial threshold as a percentage from which the proposition is considered as denied, f) the decider triggers a timer and defines at least one processing time, g) the decider transmits said proposition with the processing time via the distributed network to all the voters, h) during the processing time, according to the responses that it receives, the decider determines the confirmation response percentage and the denial response percentage, then confirms or denies the proposition by comparing the percentages thus determined with the confirmation and denial thresholds; following the processing time, if no decision has been made, the decider gathers all the responses available and determines the confirmation response percentage and the denial response percentage, then confirms or denies the proposition by comparing the percentages thus determined with the confirmation and denial thresholds; the process being further characterised in that the decider associates a level of priority with the proposition, and in that the processing time is specific to this level of priority, in that at least one voter is configured to apply steps a) to h) hereinabove to other so-called secondary processing units by considering the same proposition, and in that the decider assigns a level of priority to the proposition subjected to said secondary processing units greater than or equal to the level of priority assigned to the proposition and propagates said proposition to said secondary processing units. a) the decider determines a proposition upon reception of a request to allocate a PCI number to an eNodeB of the mobile telephone network, the proposition being a PCI number, Physical Cell Identity, that the decider wants to present in response to said request, the decision to be made being the confirmation or the denial of the PCI number to be presented in response to the request received, b) the decider selects a set of so-called voter processing units, to analyse the proposition and to present a response, this response comprising a confirmation of the proposition, a denial of the proposition or a "no opinion" response, c) the decider defines a percentage weighting for each voter or group of voters thus selected, d) the decider defines a confirmation threshold as a percentage from which the proposition is considered as confirmed, e) the decider defines a denial threshold as a percentage from which the proposition is considered as denied, f) the decider triggers a timer and defines at least one processing time, g) the decider transmits said proposition with the processing time via the distributed network to all the voters, h) during the processing time, according to the responses that it receives, the decider determines the confirmation response percentage and the denial response percentage, then confirms or denies the proposition by comparing the percentages thus determined with the confirmation and denial thresholds; following the processing time, if no decision has been made, the decider gathers all the responses available and determines the confirmation response percentage and the denial response percentage, then confirms or denies the proposition by comparing the percentages thus determined with the confirmation and denial thresholds;
