A method and a system for setting up a connection over a dedicated connection interface between a user (202) connected to an access network (200), and an access resource (212), also connected to the access network (200). The impact on signalling messages, being defined for a V5.2 interface between the access network (200) and a service node (204) for setting up the connection, is minimised by using an existing standardised V5.2 identity field for uniquely identifying the access resource (212). A free V5.2 address identity, which is not used for links of the V5.2 interface (208), is used for identifying the access resource (212).
