iSSP Terminal eSIM Profile Installation via Local Bundle Assistant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods do not define a process for remote SIM provisioning (RSP) protocol in terminals equipped with an integrated smart secure platform (iSSP), preventing the download of eSIM profiles using eSIM infrastructure such as an SM-DP+ server and activation code.
Innovation Solution
A method and apparatus for installing an eSIM profile in a terminal with an iSSP, involving receiving an activation code, obtaining eSIM bundle information, performing eSIM profile download procedures if an appropriate bundle is identified, and generating or obtaining an eSIM bundle if not identified, allowing eSIM profile installation even with only an SM-DP+ server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an iSSP terminal uses existing methods without RSP protocol definition, then the terminal structure remains simple, but eSIM profile download and installation cannot be performed
Solution Approach 1:
The patent introduces a Local Bundle Assistant (LBA) as an intermediary component that mediates between the iSSP terminal and the SM-DP+ server. The LBA handles the complex RSP protocol processing, activation code verification, and bundle information management, allowing the terminal itself to perform eSIM profile downloads without requiring additional external infrastructure or complex terminal-side implementation.
2Adaptability or versatility
If eSIM infrastructure (SM-DP+ server, activation code) is used, then eSIM profile download is enabled, but iSSP terminals lack the defined process to utilize these resources
Solution Approach 1:
The patent makes the iSSP terminal universal by enabling it to perform multiple functions: it can operate both as a traditional terminal and as an eSIM-capable device. The LBA component provides multi-functionality by handling activation code processing, bundle information retrieval, and profile download operations, allowing the same terminal infrastructure to support both legacy and eSIM services without requiring separate dedicated systems.
Solution Approach 2:
The patent implements feedback mechanisms where the LBA continuously monitors the terminal's bundle information, compares it with requirements from activation codes, and adjusts the download process accordingly. The system receives feedback from the SM-DP+ server regarding download status, profile installation results, and error conditions, using this information to retry or abort operations as needed, ensuring reliable profile deployment.
3Manufacturing precision
If bundle information is obtained and verified, then correct profile download is ensured, but additional processing steps increase complexity
Solution Approach 1:
The patent applies preliminary action by having the terminal obtain and verify bundle information before initiating the actual profile download process. The LBA retrieves bundle information from the iSSP, verifies it against the activation code requirements, and prepares the download parameters in advance. This preliminary verification ensures that the subsequent download process is accurate and avoids errors, while the complexity is managed through automated preprocessing rather than complex real-time verification during download.
Data Source
AI summary
A method and apparatus for providing a communication service by installing an eSIM profile even in a terminal to which an iSSP is applied. The method comprises: detecting whether information is input information for eSIM profile download input information from a terminal to which an iSSP is applied, and determining whether the terminal supports the same. Collecting eSIM bundle information of the iSSP by the terminal; selecting an eSIM bundle to be used by referring to a condition designated by the terminal from among the collected eSIM bundles; if there is no bundle to be used or when it is determined that no eSIM bundle is used among existing eSIM bundles, generating an eSIM bundle by the terminal itself or providing an eSIM bundle via communication with the terminal and a server; and on the basis of eSIM bundle information, downloading and installing an eSIM profile package.
