eUICC Profile Readiness Checks for Reliable eSIM Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eSIM-equipped electronic devices face delays and failures in profile downloading due to missed push messages or lack of callback messages from communication carrier servers, leading to indefinite waiting and incomplete profile installation.
Innovation Solution
The electronic device includes an embedded universal integrated circuit card (eUICC) and a processor that allows for profile check requests through various user interfaces and includes information in response messages to indicate profile readiness, enabling direct identification and download even when push or callback messages are missed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If push messages or callback messages are used to notify profile readiness, then the system can automatically initiate profile download, but the device may experience indefinite waiting and download failures when messages are missed
Solution Approach 1:
The patent implements a feedback mechanism where the device actively checks profile readiness status by sending requests to the server and receiving response messages. This continuous feedback loop allows the device to detect when the profile is ready without relying solely on push or callback messages, thereby reducing waiting time and improving download reliability.
Solution Approach 2:
The device performs self-service by autonomously initiating profile status check requests and processing the responses. This self-service approach reduces dependency on external notification mechanisms and enables the device to take control of the profile download process, minimizing delays caused by missed messages.
2Ease of operation
If the device waits for push messages or callback messages to initiate profile download, then automatic download can be triggered, but the device may experience delays and incomplete installation when messages are not received
Solution Approach 1:
The patent implements preliminary action by having the device send profile status check requests before the actual profile download is needed. This proactive approach allows the device to detect profile readiness in advance and initiate the download process promptly, ensuring complete installation even when push or callback messages are missed.
Solution Approach 2:
The system uses feedback through response messages from the server to confirm profile readiness. The device continuously monitors the profile status by sending check requests and processing responses, creating a reliable feedback mechanism that ensures automatic download is triggered at the appropriate time without delays or incomplete installations.
3Productivity
If the device continuously checks for profile readiness, then download can be initiated promptly when ready, but excessive checking may increase network traffic and energy consumption
Solution Approach 1:
The patent implements periodic action by having the device send profile status check requests at regular intervals rather than continuously. This periodic checking approach balances the need for prompt download initiation with the constraint of energy consumption, allowing the device to detect profile readiness efficiently without excessive network traffic or energy usage.

AI summary
An electronic device includes at least one embedded universal integrated circuit card (eUICC) each storing at least one subscriber identification information, and at least one processor electrically connected with the eUICC. The at least one processor may be configured to control to transmit, to a first server, a first request message including information about an operation related to a subscription or a subscription transfer based on the eUICC and receive a first response message from the first server, in response to the transmission of the first request message. The first response message may include information indicating that a profile to be provided for the eUICC is not ready in response to the first request message.
