Abstract
This publication describes an alternative framework for managing delayed embedded Subscriber Identity Module (eSIM) transfers on mobile devices that avoids needing a carrier’s Entitlement Configuration Server (ECS) to manage cloud messaging tokens. During a delayed transfer, a carrier’s Subscription Management Data Preparation (SM-DP+) server notifies a Subscription Management Discovery Service (SM-DS) server when an eSIM profile becomes available. The SM-DS server then triggers a cloud messaging push notification to the mobile device’s Local Profile Assistant (LPA). To ensure a seamless user experience the LPA hides the raw push notification from the user interface. Upon receiving this hidden push notification, the LPA automatically triggers an acquireConfiguration request to the ECS to retrieve the activation code and query profile availability. This enables a seamless status update on the device’s eSIM transfer screen while needing minimal backend integration effort from carriers.
