eSIM Profile Transfer Using Identifier Verification for Push Message Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing on-device service activation (ODSA) procedure for downloading profiles to eSIMs in wireless communication systems is prone to errors due to delayed download schemes, multiple enabled profiles, and profile transfer failures, leading to authentication issues when existing profiles are deactivated or deleted.
Innovation Solution
A conditional profile downloading method from an SM-DP+ server, which includes identifying and verifying identifiers to ensure accurate profile transfer and updating authentication information without a new authentication procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device uses delayed download scheme for profile transfer, then the communication carrier can control the profile download timing, but multiple push messages may be received causing errors
Solution Approach 1:
The electronic device performs preliminary actions by storing identifier information received from the first server before the profile transfer is complete. When push messages arrive later, the device can identify and ignore messages with mismatched identifiers, preventing errors while maintaining the delayed download scheme's benefits.
Solution Approach 2:
The system implements feedback mechanisms where the electronic device sends identifier information to the first server, which then includes this identifier in subsequent push messages. This feedback loop enables the device to verify message authenticity and prevent processing duplicate or erroneous messages.
2Adaptability or versatility
If the electronic device transfers profile to external device, then the existing profile can be moved to new device, but authentication may fail when existing profile is deactivated or deleted
Solution Approach 1:
The electronic device performs preliminary authentication using the existing profile before deactivation or deletion occurs. The device stores the authentication result and uses it to access the entitlement server during the profile transfer process, ensuring authentication succeeds even after the original profile is deactivated.
Solution Approach 2:
The patent introduces an intermediary mechanism where the electronic device acts as a mediator between the existing profile and the new profile. The device maintains authentication context and uses stored authentication information to bridge the transition, allowing seamless access during profile transfer without requiring the existing profile to remain active.
3Adaptability or versatility
If the electronic device receives multiple push messages for multiple profiles, then multiple profiles can be downloaded, but the device cannot identify which message corresponds to which profile
Solution Approach 1:
The patent segments push messages by incorporating unique identifier information for each profile into individual messages. The electronic device processes and stores these identifiers separately, enabling clear distinction between multiple profiles and their corresponding messages, thus eliminating identification difficulties.
Solution Approach 2:
The system implements feedback where the electronic device sends profile-specific identifier information to the server, which then incorporates this information into subsequent push messages. This feedback mechanism ensures each message is clearly tagged with its associated profile identifier, making message-profile mapping unambiguous.

AI summary
The disclosure provides an electronic device (101), the electronic device comprises communication circuitry (190), one or more processors including processing circuitry (120), and memory (130) storing instructions, and the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to: receive, from an external electronic device (102; 104; 700) via the communication circuitry, authentication information related to a procedure for transferring a profile from the external electronic device to the electronic device, in response to receiving the authentication information, identify a first identifier for identifying the procedure, transmit, to a first server (520) via the communication circuitry, a request message, that includes the first identifier, for requesting transfer of the profile, in response to transmitting the request message, receive, from the first server or a second server (210; 560) different from the first server via the communication circuitry, a response message including information for downloading a profile from a third server (220; 530), based on the response message, identify a second identifier for identifying the procedure, identify whether the second identifier is identical to the first identifier, based on the second identifier being identical to the first identifier, identify whether another response message including the second identifier has been received before receiving the response message, and based on whether the another response message has been received, identify whether to download the profile from the third server, wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to, as at least part of identifying whether to download the profile from the third server based on whether the another response message has been received: based on the another response message having not been received, download the profile from the third server via the communication circuitry based on the information for downloading the profile. Another embodiment may be possible.
