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.
