Abstract:
The use of a Trusted Execution Environment (TEE) of a user device to perform Universal Integrated Circuit Card (UICC) update may replace the conventional use of multiple SMS messages to update the UICC of a user device. A UICC update request may be sent to a UICC update service of a wireless communication network via a communication session by a trusted update application that is executing in the TEE. Subsequently, the UICC update service may send a UICC update file to the user device via the communication session for storage in the TEE. A copy of the UICC update file is then transferred from the TEE to modem software of a modem in the user device. The modem software chunks the UICC update files into multiple UICC update data chunks. The data chunks are sent by the modem software to the UICC to update the UICC.

Claim (Index 20):
A user device, comprising:\n one or more processors; and memory including a plurality of computer-executable components that are executable by the one or more processors to perform a plurality of actions, the plurality of actions comprising:\n receiving, a SMS information message form a wireless communication network indicating that a Universal Integrated Circuit Card (UICC) update is available for a UICC of the user device; \n establishing a secure communication session between the user device and a UICC update service of the wireless communication network; \n sending, based on a prompt from a trusted update application that is executing in a Trusted Execution Environment (TEE) of the user device, a registration message to the UICC update service that includes a trust credential of the TEE on the user device via the secure communication session in response to the SMS information message; \n receiving a reply message from the UICC update service via the secure communication session indicating that the user device is validated for receiving the UICC update following a validation of the trust credential as being associated with the user device by a trusted authentication authority; \n sending a UICC update request from the trusted update application to a UICC update service of the wireless communication network via the secure communication session; \n storing a UICC update file that is received from the UICC update service of the wireless communication network via the secure communication session in the TEE of the user device; \n transferring a copy of the UICC update file from the TEE of the user device to modem software associated with a modem of the user device; \n chunking the UICC update files into multiple UICC update data chunks via the modem software, in which individual UICC update data chunks are equivalent to or less than in size to a maximum Short Message Service (SMS) message size; and \n sending the multiple UICC update data chunks to the UICC of the user device via a communication channel between the user device and the UICC to update the UICC, \n wherein updating the UICC of the user device via the UICC update file is a substitute for updating the UICC of the user device via multiple SMS messages that are sent from the wireless communication network to the user device.
