Dynamic Provisioning eSIM State Management for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing provisioning eSIM in wireless devices often causes a high signaling load on cellular networks during simultaneous device activations, leading to network congestion and battery power consumption issues, as they are typically configured to be active immediately upon boot-up.
Innovation Solution
The provisioning eSIM is dynamically managed to switch between inactive and active states based on user actions and system requirements, initially being configured in an inactive state to restrict network connections and conserve battery power, and then activated only when necessary, using a back-off timer to manage re-use and reduce signaling load.

Engineering Contradiction Analysis
1Speed
If the provisioning eSIM is configured to be active immediately upon boot-up to provide ready connectivity, then device activation and essential services can be accessed without delay, but network signaling load increases and battery power is consumed unnecessarily
Solution Approach 1:
The provisioning eSIM is configured to dynamically transition between inactive and active states based on operational needs. Initially inactive to conserve energy, it becomes active when essential services require network connectivity, then returns to inactive state afterward. This dynamic state management resolves the contradiction by making connectivity establishment fast when needed while minimizing energy consumption during idle periods.
Solution Approach 2:
The system implements periodic activation of the provisioning eSIM rather than continuous operation. A back-off timer controls the periodic nature of activation, allowing the eSIM to remain inactive for extended periods and only become active temporarily when device activation or essential services are required. This periodic action pattern reduces overall energy consumption while maintaining necessary connectivity capabilities.
2Productivity
If multiple wireless devices connect to the cellular wireless network simultaneously during new product launch, then all devices can be activated concurrently, but network signaling load becomes excessively high causing network congestion
Solution Approach 1:
The provisioning eSIM is pre-configured in an inactive state with all necessary credentials and parameters ready for immediate use when activated. This preliminary preparation allows the device to quickly establish network connectivity when needed without requiring extensive setup procedures, enabling concurrent device activation while minimizing the duration and intensity of signaling interactions with the network.
Solution Approach 2:
The system changes the operational parameters of the provisioning eSIM by transitioning between inactive and active states. When devices need network access during product launch, the eSIM parameter changes from inactive to active, allowing network connection. After completion of essential services, the parameter changes back to inactive, effectively controlling and reducing the overall signaling load on the network during high-volume activation periods.

AI summary
This application sets forth techniques for dynamically managing a provisioning electronic subscriber identity module (eSIM) for a wireless device. A provisioning eSIM is installed in the wireless device to provide a limited functionality connectivity option for essential services, such as device activation and user eSIM provisioning. To reduce signaling load on a network and to conserve wireless device battery power, the provisioning eSIM is reconfigured between an inactive state and an active state dynamically based on user actions and system requirements.
