Embedded universal integrated circuit card (eUICC) command processing

Abstract:

An electronic universal integrated circuit card (eUICC) performs one or more operations to increase the reliability and decrease the execution time of remote profile management (RPM) commands or local profile management (LPM) commands. In some embodiments, the eUICC scans through a received script containing RPM commands and then selectively defers some responsive actions such as refresh commands. An eSIM server that originates the script, in some embodiments, mandates performance of a refresh command after a particular RPM command by including an explicit refresh command code in the script. In some embodiments, the eSIM server includes a command instructing the eUICC to hold responsive refresh commands until the completion of the script. In some scenarios, execution of one or more RPM or LPM commands may be interfered with by a card application toolkit (CAT) session. Embodiments provided herein prioritize the RPM/LPM commands as more important than the CAT session.
