US 2025/0030514 A1 · LOGICAL CHANNEL MANAGEMENT FOR MULTIPLE eSIM PROFILES

Abstract

Techniques for managing logical channel communication for multiple electronic subscriber identity module (eSIM) profiles installed on an embedded universal integrated circuit card (eUICC), including mapping of logical channel identifier values between different logical channel labeling schemes are described herein. In a first scheme, logical channels are identified using logical channel values alone. In a second scheme, logical channels are identified using a combination of eSIM port value and channel values. An interpreter in the eUICC and/or in processing circuitry external to the eUICC can map between the logical channel labeling schemes to allow internal state machines in the eUICC and/or the processing circuitry to use the first scheme for identifying logical channels.

Dependent claims

An embedded universal integrated circuit card (eUICC) configured for operation in a wireless device, the eUICC comprising:

a first external interface;
and
a processor communicatively coupled to a memory storing instructions that, when executed by the processor, configure the eUICC to:
receive a first message via the first external interface, the first message comprising an electronic subscriber identity module (eSIM) port value and a channel value;
and
map the first message to a first logical channel of one or more logical channels associated with a first eSIM installed on the eUICC based on the eSIM port value and the channel value,
wherein a first set of one or more logical channel values are associated with one or more logical channels for communication between an external processor coupled to the eUICC and the first eSIM installed on the eUICC.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of an embedded universal integrated circuit card (eUICC), configure the eUICC to:

receive, via a first external interface of the eUICC, a first message comprising an electronic subscriber identity module (eSIM) port value and a channel value;
and
map the first message to a first logical channel of one or more logical channels associated with a first eSIM installed on the eUICC based on the eSIM port value and the channel value,
wherein a first set of one or more logical channel values are associated with one or more logical channels for communication between an external processor coupled to the eUICC and the first eSIM installed on the eUICC.
