Abstract

The present invention relates to a method for controlling a user terminal of a communications network, the user terminal having a communications unit, a subscriber identification means including a restricted using mode list, each entry of which includes an identifier (AI) and/or ID-number of a communications link and/or a class of communications links which are allowed when a restricted using mode of the user terminal is enabled, and memory means for storing entries including identifiers and associated ID-numbers of communications links. The inventive method comprises: inputting a request for a communications link (S10) and building-up requested communications links (S50), if the restricted using mode is not enabled (S20); otherwise comparing the ID-number of the requested communications link with entries of the restricted using mode list (S40) and building-up the requested communications link (S50), if the ID-number matches an entry of the restricted using mode list; otherwise rejecting the request (S45).

Claims

1. A 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) matches an entry of said restricted using mode list (EF-FDN);

otherwise

rejecting said request;

characterized by

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

2. A method according to claim 1, characterized by

checking, in case that an entry in said memory means (23) has been selected for requesting a communications link, whether or not the corresponding communications link provides access to value added services;

and

if so, comparing said identifier (AI) of said selected entry with said identifiers (A1) 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).

3. A method according to claim 2, characterized in that

said entries for communications links which provide access to value added services are stored in a corresponding list (24) in said memory means (23);

and

it is checked whether or not a selected entry is stored in said list (24) of entries for communications links which provides access to value added services for checking whether or not the corresponding communications link provides access to value added services.
