Method for loading a list of preferred networks into a secure element contained in a mobile terminal
View Patent ↗The invention relates to a method for loading a list of preferred networks into a secure element contained in a mobile terminal. The loading is accomplished when the secure element detects that it is in a roaming condition within a telecommunication network. The method consists of: i) asking ( 12 ) for an IP channel to be opened between the telecommunication network and the secure element, the request for opening originating with the secure element; ii) requesting ( 13 ) the loading of the list of preferred networks; iii) uploading ( 14 ) via the IP channel the list of preferred networks into the secure element; and iv) transmitting ( 16 ) a request by the secure element to the mobile terminal to use one of said preferred networks in said list.
1. A method for loading a list of preferred networks into a secure element contained in a mobile terminal while said secure element is in a roaming condition within a telecommunication network, comprising:
detecting, by said secure element, when the secure element is in the roaming condition within the telecommunication network; and
upon detecting that said secure element is in the roaming condition within the telecommunication network,
(i) asking for an Internet Protocol (IP) channel to be opened between said telecommunication network and said secure element, with said request for opening originating from said secure element;
(ii) requesting, by the secure element, the loading of said list of preferred networks from the telecommunication network;
(iii) uploading via said IP channel said list of preferred networks into said secure element; and
(iv) transmitting a request by said secure element to said mobile terminal to connect to one of said preferred networks in said list.
2. The method according to claim 1 , further comprising closing said IP channel between the steps iii and iv.
3. The method according to claim 1 , wherein said secure element is a chip card which is removeable from said mobile terminal.
4. The method according to claim 1 , wherein said secure element forms part of said mobile terminal.
5. The method according to claim 1 , wherein said telecommunication network is a Universal Mobile Telecommunications System (UMTS) network.
6. The method according to claim 1 , wherein said telecommunication network is a Long Term Evolution (LTE) network.
