Patent ID: 8331990

Claim:
A method of activating a SIM card in a mobile telephone network using an ODA (On Demand Activation) application that operates on a computer with an associated ODA database, the ODA database ( 4 ) containing SIM card ( 1 ) information related to SIM cards to be activated, said information being associated with a code in the ODA database, the ODA ( 2 ) including a proxy ( 7 ) logically located between a HLR/AUC ( 5 ) (Home Location Register/Authentication Center) and a MSC/VLR ( 6 ) (Mobile Services Switching Centre), and a memory of a SIM card ( 1 ) containing said code, the method comprising the sequential steps of: in a first step, when the SIM card is inserted into a mobile equipment and the mobile equipment is switched on, a message related to a registration procedure containing said code is sent from the mobile equipment to said proxy ( 7 ) via said MSC/VLR; in a second step, said message is halted in said proxy ( 7 ); in a third step, said proxy ( 7 ) is arranged to direct a message, containing said code, to said ODA application ( 2 , 4 ); in a fourth step, ODA ( 2 ) is connected to a HLR-T/AUC-T (Temporary Home Location Register/Authentication Center) in the mobile telephone network ( 5 ) in order to transfer information stored on said SIM card; in a fifth step, HLR-T/AUC-T sends information to said ODA ( 2 ) which state that a temporary subscription is ready for use; in a sixth step, said proxy ( 7 ) relays the halted message to said HLR-T/AUC-T ( 5 ); in a seventh step, when said proxy ( 5 ) relays the halted message to said HLR-T/AUC-T ( 5 ), the ODA ( 2 ) is connected to the SIM-card in order to update the SIM-card with a card definition file including permanent subscription data; and in an eight step, the ODA ( 2 ) is connected to a HLR/AUC ( 5 ) in order to transfer information stored on said updated SIM card, whereby the HLR/AUC is arranged to set up a permanent subscription.
