Abstract
The invention concerns a cellular radiocommunication system comprising a network core (21) including switches (28, 30, 32), one or several gateways (28, 32) to external networks, subscriber management means (33) and billing management means (34, 35). Several radio access networks (22, 40), including each base stations (24, 42) capable of radio communication with mobile stations (23), are connected to the network core switches. Said radio access networks include an access network (22) managed with the network core by a cellular operator and at least an additional access network (40) 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.
