Abstract
Duplicate processing of events registered at a root server is avoided. An electronic subscriber identity module (eSIM) server pushes, to a root server, data in the form of notification data portions indicating that commands or events need to be processed by a device. The device includes an embedded universal integrated circuit card (eUICC). The device pulls a notification list from the root server. The notification list includes one or more notification data portions. The device checks a given notification data portion to see if it represents a duplicate before communicating with the eSIM server to perform further processing related to the event. The device bases the check for duplication on an event history and/or on a hash value where the hash value is based on one or more eSIMs installed in the eUICC. The device is able to prioritize notification data portions before processing them.
