US 2025/0031050 A1 · MINIMAL CONFIGURATION SYNTHETIC eSIM PROFILES FOR WIRELESS DEVICES

Abstract

Embodiments described herein relate to wireless communications, including methods and apparatus for configuring synthetic electronic subscriber identity module (eSIM) profiles for wireless devices based on user credentials. A synthetic eSIM profile is generated at a wireless device based on transformation of user credentials that include a user identity and user cryptographic information. The user identity can include an identifier for a user account, and the user cryptographic information can include a password for the user account. The wireless devices can use the synthetic eSIM profile to obtain and load one or more fully functional eSIM profiles to an embedded universal integrated circuit card (eUICC) to without requiring a bootstrap eSIM profile or non-cellular wireless access.

Dependent claims

A method for supporting synthetic electronic subscriber identity modules (eSIMs), the method comprising:

obtaining one or more public land mobile network (PLMN) identifier (ID) values;
connecting a home subscription server (HSS) to a third generation partnership project (3GPP) mobile application part (MAP) network to enable reachability of the HSS from a local cellular wireless access network, wherein the HSS is linked to a secure credential storage that stores a plurality of synthetic symmetric key (K) values, each synthetic K value associated with a corresponding user identity;
establish a roaming agreement with a mobile network operator (MNO) associated with the local cellular wireless access network,
configuring routing to the HSS from the local cellular wireless access network;
and
allowing a connection to the local cellular wireless access network from a wireless device that uses a synthetic eSIM profile that includes a synthetic K value.
