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.
