eUICC Push Service Registration for Remote Profile Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in efficiently managing and updating profiles, such as SIM cards, across different networks, leading to inconvenience for users who need to physically obtain new SIM cards for different service providers, especially when traveling or switching carriers, and there is a lack of efficient methods for remote profile management and event registration in wireless communication systems.
Innovation Solution
A method and device for managing profiles remotely through a UICC/eUICC, allowing for the download and installation of profiles using OTA technology, and enabling efficient event registration and management in a communication system by interacting with subscription relay servers and profile providing servers, using control signals and processors to facilitate profile management and event registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a terminal registers for event notification services with a subscription relay server, then the terminal can receive event registration information, but the system complexity increases due to multiple servers and protocols
Solution Approach 1:
The subscription relay server acts as an intermediary between the terminal and the network event system. It receives event registration requests from terminals, validates them against subscription criteria, and forwards matching events to appropriate terminals. This mediator approach simplifies the terminal's operation while managing system complexity centrally.
Solution Approach 2:
Terminals perform preliminary action by registering their event notification preferences and criteria in advance with the subscription relay server. This pre-registration mechanism allows the system to automatically match and deliver events without requiring real-time complex queries or manual configuration during event occurrence.
2Adaptability or versatility
If the system provides comprehensive event registration notification functions, then service coverage is improved, but the processing time and resource consumption increase
Solution Approach 1:
The system implements partial action by processing only the essential event registration criteria and subscription information rather than all possible event details. The subscription relay server filters and processes only the necessary registration parameters, reducing processing time while maintaining comprehensive service coverage through efficient data handling.
3Adaptability or versatility
If the terminal manages multiple event registration notifications, then the functionality is enhanced, but the management complexity and potential for errors increase
Solution Approach 1:
The subscription relay server provides self-service functionality by automatically managing event registration, validation, and delivery without requiring manual intervention or complex management operations from the terminal. The server handles subscription criteria validation, event matching, and notification delivery autonomously, reducing management complexity while enhancing functionality.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method comprises transmitting to a subscription manager discovery service (SM-DS) information indicating a support of a push service, receiving from the SM-DS a list of push services supported by the SM-DS, selecting at least one push service based on the list of push services supported by the SM-DS, generating an embedded Universal Integrated Circuit Card (eUICC) signature based on an indicator indicating at least one selected push service and a push token, and transmitting to the SM-DS the indicator, the push token, and the eUICC signature.
