1. Method for controlling a user terminal (10) of a communications network, said user terminal (10) having a communications unit (11), a subscriber identification means (12) including a restricted using mode list (EF-FDN) each entry of which includes an identifier (AI) and/or an ID-number (DN, SSCS) of a communications link and/or a class of communications links which are allowed when a restricted using mode of said user terminal (10) is enabled, and memory means (23) for storing entries including identifiers (AI) and associated ID-numbers (DN, SSCS) of communications links;

  • said method comprising the steps of;

    inputting a request for a communications link; and

    building-up said requested communications link, if said restricted using mode is not enabled;

    otherwise comparing said ID-number (DN, SSCS) of said requested communications link with said entries of said restricted using mode list (EF-FDN); and

    building-up said requested communications link, if said ID-number (DN, SSCS) snatches an entry of said restricted using mode list (EF-FDN);

    otherwise rejecting said request;

    characterized by comparing, in case that an entry in said memory means (23) has been selected for requesting a communications link, said identifier (AI) of a selected entry with said identifiers (A1) of said restricted using mode list (EF-FDN); and

    building-up said requested communications link, if said identifier (A1) matches an entry of said restricted using mode list (EF-FDN);

    otherwise continuing with comparing said ID-number of said requested communications link with said entries of said restricted using mode list (EF-FDN).
