ESIM Activation via Near Field Communication in Wireless Routers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ESIM card activation methods for wireless routers are limited, as they require a wireless network connection to receive a configuration file, leading to activation failures when no Wi-Fi is available, and cannot be used globally across multiple operators.
Innovation Solution
The method employs a near field communication module to receive and install a configuration file for ESIM card activation in wireless routers, enabling real-time activation even without a wireless network connection, using Bluetooth or NFC for data transmission between the router and a user terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ESIM-enabled device connects to Wi-Fi network to obtain configuration file, then the configuration file can be received and installed, but the activation cannot be performed when Wi-Fi is unavailable
Solution Approach 1:
The patent introduces a configuration file transmission interface (such as NFC or Bluetooth) as an intermediary to transfer the configuration file from the terminal device to the router without requiring Wi-Fi network connection. This mediator enables the activation process to proceed in environments where Wi-Fi is unavailable, thus resolving the contradiction between activation reliability and network environment adaptability.
2Ease of manufacture
If a configuration file is preset for a specific operator, then the registration can be completed for that operator, but the solution cannot be used globally across multiple operators
Solution Approach 1:
The patent applies preliminary action by having the terminal device download and prepare the configuration file from the operator's website before transmission to the router. This allows the configuration file to be customized for specific operators in advance, while the router itself remains operator-agnostic. The terminal device acts as a preparation station that adapts the configuration to the desired operator before transferring it via the transmission interface, thus achieving both ease of manufacture and global operator compatibility.
3Ease of operation
If the router requires Wi-Fi connection for activation, then network services can be established, but users must query network names and passwords manually
Solution Approach 1:
The patent implements self-service by enabling the router to automatically obtain and install the configuration file through the transmission interface without requiring users to manually input network names and passwords. The system autonomously completes the activation process by receiving the configuration file from the terminal device and applying it to the ESIM card, thereby eliminating manual queries and reducing activation time while maintaining ease of operation.

AI summary
Embodiments of the present invention disclose an ESIM card activation method, a wireless router, and a user terminal. The method includes: receiving, by the wireless router by using a near field communication module, a configuration file that is used to activate an ESIM card and that is sent by a user terminal; installing, by the wireless router, the configuration file to complete ESIM card activation; and establishing, by the wireless router, a first wireless network by using the activated ESIM card. According to this application, when the wireless router is unable to connect to a wireless network, the wireless router can receive, by using the near field communication module, the configuration file used to activate the ESIM card, and a user can activate the ESIM card of the wireless router in real time based on a requirement.
