The invention concerns a cellular radiocommunication system comprising a network core ( ) including switches ( ), one or several gateways ( ) to external networks, subscriber management means ( ) and billing management means ( ). Several radio access networks ( ), including each base stations ( ) capable of radio communication with mobile stations ( ), are connected to the network core switches. Said radio access networks include an access network ( ) managed with the network core by a cellular operator and at least an additional access network ( ) having a substantially less extensive radio coverage and a substantially wider bandwidth than the one managed by the cellular operator. When setting up a communication with a mobile station through the network core and one of the access networks, a report message is generated specifying the access network concerned.
