The present invention relates to a method and system for providing access to a cellular network ( 8 ), wherein a terminal device ( 1 ) is connected to an access device ( 2 ) according to access specifications of a broadband access network ( 12 ) which is not specifically designed to be used as a part of cellular network ( 8 ). The terminal device ( 1 ) indicates to the access device ( 2 ) that it wishes to be connected to the cellular network ( 8 ), and a session or call and a radio bearer is setup between the terminal device ( 1 ) and the cellular network ( 8 ). To achieve this, a service node ( 5 ) provided in the cellular network ( 8 ) requests a suitable access bearer from the access network ( 12 ) and the access device ( 2 ) sets up a corresponding access channel towards the terminal device ( 1 ). The terminal device ( 1 ) then associates the access channel to the correct radio bearer by using a corresponding identification. Thereby, service functions of the cellular network, e.g. UMTS services, can be distributed via any access network and existing broadband or high-speed access networks can be implemented in new cellular network structures. A huge capacity enhancement can thus be offered to the network operators of the cellular network without any standardization effort or license fee and at very small investment and maintenance costs.
