APPARATUS AND METHODS FOR ELECTRONIC SUBSCRIBER IDENTITY MODULE (ESIM) INSTALLATION AND INTEROPERABILITY

摘要

Methods and apparatus for managing processing of electronic Subscriber Identity Modules (eSIM) data at a mobile device are disclosed. An eSIM management entity of an embedded Universal Integrated Circuit Card (eUICC) in the mobile device obtains an encrypted eSIM package, decrypts the eSIM package to obtain eSIM contents formatted generically and not specifically tailored to requirements of the eUICC. In some embodiments, the eSIM contents are formatted based on an abstract syntax notation (ASN) distinguished encoding rules (DER) format. The eSIM management entity parses the formatted eSIM contents to retrieve individual eSIM components and installs each eSIM component for the eSIM in an eSIM security domain on the eUICC. In some embodiments, the eSIM management entity acts as a local, personalization server to provide local Trusted Service Manager (TSM) server functionality for eSIM installation that transforms “generically formatted” eSIM contents into eSIM components that match specific requirements of the eUICC.

1. A method for managing electronic Subscriber Identity Modules (eSIMs) on an embedded Universal Integrated Circuit Card (eUICC) included in a mobile device, the method comprising:
by the eUICC:
receiving, from a provisioning server via a secure connection, an encrypted eSIM package;decrypting the eSIM package to obtain formatted contents of an eSIM, wherein a format of the contents of the eSIM is not specific to requirements of the eUICC;parsing the formatted contents of the eSIM to retrieve a set of individual components of the eSIM; andinstalling individual components of the eSIM in an eSIM security domain on the eUICC.
