Abstract:
1. A method for controlling communication among an universal integrated circuit card (UICC), a handset including the UICC, and an external device associated with an external application running outside of the handset, the method comprising: switching on the UICC via the handset; after the switching, executing a first initialization procedure via the handset to establish a first communication session between the handset and the UICC; after the executing of the first initialization procedure, executing a second initialization procedure for exchanging a connection request between the handset and the external device to establish a second communication session between the UICC and the external device, the handset causing the UICC to reset when the connection request is received and during the second initialization procedure; using the UICC to retrieve a unique handset identification number of the handset after completing the first initialization procedure; after the retrieving of the unique handset identification number, storing the unique handset identification number in a memory of the UICC; using the UICC to retrieve an attribute of the external device via the handset after completing the second initialization procedure; using the UICC to compare the unique handset identification number of the handset with the attribute of the external device to distinguish the second communication session from the first communication session; and when the unique handset identification number of the handset and the attribute of the external device do not match and subsequently receiving a request from the external device for a record stored in the UICC, using the UICC to reply with an empty record.
