Removable eUICC Profile Handling for Multiple Enabled Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems with eUICCs supporting multiple enabled profiles (MEP) do not adequately address the handling of multiple profiles, particularly when a profile with a 'disabling impossible' business provider policy (PPR1) is inserted, leading to inefficiencies and additional costs for terminal manufacturers due to the need for multiple eUICC modules and physical interfaces.
Innovation Solution
A method and apparatus for processing profiles in a wireless communication system involving a removable eUICC, including activation and cold reset, determining transport protocols, and managing channel openings to enable multiple profiles simultaneously, ensuring a default profile remains enabled and allowing seamless swapping between profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple eUICC modules and physical interfaces are used to support multiple enabled profiles (MEP), then the terminal can simultaneously use multiple profiles, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements MEP functionality within a single eUICC module by enabling one eUICC to host and simultaneously activate multiple profiles. The eUICC is designed with multi-profile support capability, allowing it to manage multiple communication service profiles (e.g., different carriers, IoT services) within the same physical interface and module, eliminating the need for multiple eUICC modules.
Solution Approach 2:
The patent merges multiple profile management functions into a single eUICC module. Instead of using separate eUICC modules for each profile, the system combines multiple profiles into one eUICC, allowing simultaneous activation and management of multiple profiles through a unified interface and control mechanism.
2Adaptability or versatility
If multiple eUICC modules are installed to support MEP, then multiple profiles can be simultaneously enabled, but the terminal space and manufacturing costs increase
Solution Approach 1:
The eUICC module is designed with universal multi-profile support, enabling a single module to simultaneously host and activate multiple profiles. This multi-functional design allows the terminal to support multiple communication services (different carriers, IoT platforms, etc.) within the same physical space, eliminating the need for additional module slots.
Solution Approach 2:
The patent combines multiple profile storage and activation capabilities into a single eUICC module, reducing the physical space required in the terminal. By merging what would traditionally require multiple separate modules into one unified eUICC, the terminal's internal space is optimized while maintaining full multi-profile functionality.
3Adaptability or versatility
If traditional eUICC handling methods are used with MEP support, then profile management becomes complex especially when PPR1 profiles are inserted, but the system can support multiple enabled profiles
Solution Approach 1:
The patent implements dynamic profile management mechanisms that automatically adapt when profiles are inserted or activated. The system dynamically determines the operational mode (MEP or non-MEP) based on the inserted eUICC's capabilities and automatically adjusts profile handling procedures. When a PPR1 profile is detected, the system dynamically manages baseband connections and profile activations without requiring complex manual configuration.
Solution Approach 2:
The eUICC and terminal system perform self-service profile management by automatically detecting MEP capability and handling profile insertions without extensive manual intervention. The system autonomously manages profile activations, baseband assignments, and mode switching based on the inserted eUICC's characteristics and the inserted profiles' requirements, reducing processing complexity.

AI summary
A method and apparatus of a user equipment (UE) for a communication technique that converges a 5G communication system for supporting a higher data rate after a 4G system with IoT technology, and a system, is provided. The method comprises: performing activation and cold reset for configuring an operating environment for a removable eUICC supporting a MEP mode; receiving an ATR message indicating whether the eUICC supports at least one eUICC functionality; determining a transport protocol based on the received ATR message; transmitting an APDU message indicating whether the UE supports eUICC-related capability; receiving a response message including a response code; determining to operating in a non-MEP mode; transmitting a command APDU message for MANAGE CHANNEL open transmitted for channel open; receiving a normal response message for generating a basic channel; and performing initialization between the eUICC and the UE.
