iSSP Terminal eSIM Profile Installation via SM-DP+ Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods do not enable the download and installation of an eSIM profile in a terminal equipped with an integrated smart secure platform (iSSP) using eSIM infrastructure, such as an SM-DP+ server and activation code, due to the lack of defined remote SIM provisioning (RSP) protocol support.
Innovation Solution
A method is provided to enable the installation of an eSIM profile in a terminal with an iSSP by detecting activation codes, retrieving and selecting eSIM bundles, generating bundles if necessary, and processing eSIM profile downloads through an integrated secure service platform, allowing communication service providers with only an SM-DP+ server to offer eSIM services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If eSIM profile download is enabled in iSSP terminal, then service provision capability is improved, but device complexity increases due to protocol integration requirements
Solution Approach 1:
The iSSP terminal is enhanced to perform multiple functions by integrating eSIM profile download capability alongside existing UICC services. The terminal can now both传统的UICC card services and eSIM profile management through the same secure platform, allowing service providers to offer diverse services (dual SIM functions, eUICC support) without adding separate hardware systems.
Solution Approach 2:
The patent introduces an intermediary mechanism (local profile assistant or bundle assistant) that mediates between the iSSP terminal and the SM-DP+ server. This intermediary handles the complex RSP protocol interactions, activation code processing, and profile download operations, shielding the terminal's core security platform from protocol complexity while enabling eSIM functionality.
2Ease of operation
If RSP protocol is integrated into iSSP terminal, then eSIM profile installation is enabled, but manufacturing complexity increases
Solution Approach 1:
The necessary software components and protocol handlers for eSIM profile installation are pre-integrated into the iSSP terminal during the manufacturing process. The terminal is pre-configured with the RSP protocol stack, activation code processing logic, and bundle management capabilities, so that end users receive a ready-to-use device without requiring post-manufacturing configuration or updates.
3Adaptability or versatility
If eSIM bundle management is added, then profile download flexibility is improved, but device complexity increases
Solution Approach 1:
The eSIM profile delivery system is segmented into distinct functional components: activation code management, bundle information retrieval, profile download, and installation. Each component is handled by dedicated software modules (local profile assistant, bundle assistant, secure service platform) that operate independently but coordinate through standardized interfaces, making the overall system manageable despite its multifunctionality.

AI summary
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). 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.
