A method for switching off at least part of a communication network , the communication network comprising a plurality of access points coordinated in a centralised manner by a master device , the access points and the master device being interconnected with each other by a backhaul network , each access point managing a so-called fronthaul wireless network , a station being able to be associated with a fronthaul network of the communication network , the method being implemented by the master device and being characterised in that it comprises: - obtaining from each access point at least one item of information relating to each station in the communication network associated with said access point or which is disassociated from said access point , said at least one item of information obtained comprising association information indicating with which fronthaul network the station is associated or from which fronthaul network the station is disassociated, and further comprising information representing a signal level received by the access point coming from the station , - determining , for each station in the communication network , whether the station is associated with a fronthaul network or disassociated from any fronthaul network according to the association information, - determining , for each station in the communication network , whether the station is mobile or fixed according to a variation in the received signal level coming from the station , - determining , for each mobile station dissociated from any fronthaul network , the last fronthaul network with which the station (!50) was associated according to the association information, said last fronthaul network being said to be critical, - initiating a phase of switching off at least one non-critical fronthaul network when all the mobile stations are disassociated from any fronthaul network . - obtaining from each access point at least one item of information relating to each station in the communication network associated with said access point or which is disassociated from said access point , said at least one item of information obtained comprising association information indicating with which fronthaul network the station is associated or from which fronthaul network the station is disassociated, and further comprising information representing a signal level received by the access point coming from the station , - determining , for each station in the communication network , whether the station is associated with a fronthaul network or disassociated from any fronthaul network according to the association information, - determining , for each station in the communication network , whether the station is mobile or fixed according to a variation in the received signal level coming from the station , - determining , for each mobile station dissociated from any fronthaul network , the last fronthaul network with which the station (!50) was associated according to the association information, said last fronthaul network being said to be critical, - initiating a phase of switching off at least one non-critical fronthaul network when all the mobile stations are disassociated from any fronthaul network . <EOS>
