Patent ID: 10015165

Abstract:
Disclosed herein is a technique for managing one or more electronic Subscriber Identity Modules (eSIMs) on an embedded UICC (eUICC). In particular, the technique involves leveraging the GlobalPlatform™ Specification and/or other telecommunication standards to support the eSIMs on the eUICC. Each eUICC can include an Issuer Security Domain (ISD) owned by a device manufacturer and an eSIM manager that manages the plurality of eSIMs on the eUICC. Notably, binaries of one or more applications shared between different eSIMs can be standardized and stored in a manner that enables each eSIM to utilize the one or more applications (via the eSIM manager) without needing to individually store the binaries. Using this approach, the overall size and complexity of each eSIM can be reduced, which can increase the amount of available memory within the eUICC as well as the overall performance of the eUICC.
