Remote SIM Profile Management via Message Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when switching between mobile communication operators, as they need to physically obtain a new SIM card, especially when traveling, and roaming services often come with high costs and contractual limitations.
Innovation Solution
A method and apparatus that allow a terminal to download and manage a SIM profile remotely via a message service like SMS, MMS, or OTT, enabling efficient selection and installation of communication services without physical card changes, using a profile-related message with identification information and event download information to facilitate seamless service connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users physically obtain a new SIM card when switching operators, then service switching is achieved, but user convenience deteriorates and time loss increases
Solution Approach 1:
The patent replaces the mechanical system of physical SIM card handling with an electronic message-based system. The profile download information is transmitted via SMS, MMS, or OTT messages, eliminating the need for physical card acquisition and insertion. Users receive electronic instructions that automatically initiate profile downloads, substituting manual physical operations with automated electronic processes.
Solution Approach 2:
The patent creates and transmits a digital copy of the profile download information through message services. Instead of requiring users to physically obtain and handle a new SIM card, the system generates an electronic message containing profile information that can be copied and transmitted instantly, allowing users to switch operators without physical card handling.
2Adaptability or versatility
If roaming services are used for international communication, then service availability is improved, but cost increases and contractual limitations are imposed
Solution Approach 1:
The patent enables users to download operator profiles before traveling internationally. By receiving profile download information via message services in advance, users can prepare their terminals with the necessary profiles for foreign networks, avoiding the need to purchase expensive roaming services or physical SIM cards at the destination.
3Extent of automation
If message services are used for profile transmission, then user intervention is reduced and errors are minimized, but message service dependency increases
Solution Approach 1:
The patent implements a self-service mechanism where the terminal automatically processes received messages containing profile download information. The terminal extracts the profile information from the message and automatically initiates the download process without requiring user intervention, allowing the system to serve itself by leveraging existing message service infrastructure.

AI summary
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure discloses a terminal including a transmission and reception unit and at least one processor. The at least one processor controls the transmission and reception unit so that the transmission and reception unit receives a message such as an SMS, an MMS, or an OTT including event download information from a communication operator server, searches for event download information from the received message such as the SMS, the MMS, or the OTT, transmits the event download information to another terminal if necessary, and receives an event from a profile server with reference to the event download information.
