IN-FIELD REMOTE PROFILE MANAGEMENT FOR WIRELESS DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17661277 titled 'IN-FIELD REMOTE PROFILE MANAGEMENT FOR WIRELESS DEVICES

Simplified Explanation

This patent application describes techniques for managing electronic subscriber identity module (eSIM) profiles for a wireless device. The techniques include in-field replacement of provisioning eSIM profiles.

  • The techniques involve installing public key infrastructure (PKI) information for an original equipment manufacturer (OEM) profile management server in an embedded universal integrated circuit card (eUICC) of a wireless device during manufacturing.
  • The wireless device then uses this PKI information to conduct an eSIM profile management session and verify authorization of the OEM profile management server.
  • The authorized OEM profile management server can then manage, update, and/or replace one or more eSIM profiles on the eUICC of the wireless device.
  • This allows for easy and secure management of eSIM profiles, even after the device has been manufactured and deployed in the field.


Original Abstract Submitted

The described embodiments set forth techniques for management of electronic subscriber identity module (eSIM) profiles for a wireless device, including in-field replacement of provisioning (bootstrap) eSIM profiles. Public key infrastructure (PKI) information for an original equipment manufacturer (OEM) profile management server is installed in an embedded universal integrated circuit card (eUICC) of a wireless device at a time of manufacture and used subsequently by the wireless device to conduct an eSIM profile management session and verify authorization of the OEM profile management server to manage, e.g., update and/or replace, one or more eSIM profiles on the eUICC of the wireless device
