eSIM Profile Switching for Seamless Wireless Network Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack efficient mechanisms for dynamically switching between wireless communication networks to maintain quality of service (QoS) without disrupting data transmission, especially when roaming agreements are not in place.
Innovation Solution
An information handling system with an embedded Subscriber Identity Module (eSIM) profile switching module that coordinates with a core communication network to seamlessly switch between wireless networks, ensuring uninterrupted data transmission by scanning for stronger signals and negotiating roaming agreements as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system switches between wireless networks to maintain quality of service, then network efficiency and user experience are improved, but call dropping or IP session disconnection may occur during the switching process
Solution Approach 1:
The system performs preliminary actions by establishing roaming agreements with neighboring networks in advance and preparing alternative eSIM profiles before network switching is needed. This allows the system to quickly switch networks without disrupting ongoing calls or IP sessions, as the necessary credentials and network parameters are already in place.
Solution Approach 2:
The patent introduces an intermediary mechanism (the eSIM profile switching module coordinated with the core communication network) that manages the transition between networks. This intermediary handles the complex coordination required to switch networks seamlessly, ensuring that call continuity and IP session stability are maintained throughout the switching process.
2Productivity
If the system scans for stronger wireless signals to maintain quality of service, then network performance is improved, but system complexity and processing requirements increase
Solution Approach 1:
The eSIM profile switching module serves multiple functions: it scans for available networks, evaluates signal strength, manages eSIM profile selection, and coordinates with the core communication network. By consolidating these diverse functions into a single multi-functional module, the system reduces overall complexity while maintaining the ability to scan for and switch to stronger signals.
3Ease of operation
If the system maintains seamless network switching without dropping calls, then user experience is improved, but the switching mechanism becomes more complex
Solution Approach 1:
The system implements self-service mechanisms where the eSIM profile switching module automatically monitors network conditions, initiates switching decisions, and coordinates with the core communication network without requiring user intervention. This automation maintains seamless user experience while the complexity is contained within the automated switching mechanism.

AI summary
An information handling system may include a processor; a memory; a network interface device to communicatively couple the information handling system to a first wireless communication networks of a plurality of wireless communication networks; an embedded subscriber identity module (eSIM) to provide data descriptive of wireless communication network-specific information to authenticate the information handling system; and an eSIM profile switching module to: monitor for signal strengths of each of a plurality of wireless communication networks. Upon discovering that the first wireless communication network has insufficient quality of service to sustain data transmission, send a request to a wireless communication network switching utility at a core communication network requesting roaming during a switch between the eSIM profile for a default wireless communication network to the second wireless communication network; and switch communication to the second wireless communication network while avoiding wireless service interruption with roaming if available.
