An object of the present invention is a method for the handling of user access-dependent information in a system comprising a core network subsystem accessed by an access network, said method comprising: a step wherein an entity of said core network subsystem obtains user access-dependent information from said access network, a step wherein an entity of said core network subsystem signals to another entity, in the context of a core network subsystem procedure relating to a user's terminal, user access-dependent information obtained from said access network, a step wherein an entity of said core network subsystem uses user access-dependent information obtained from said access network, for control of service delivery to said user.
