Wi-Fi Access Control via SIM Activation Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators face challenges in recouping subsidies for user equipment (UE) as many devices are purchased without activating the SIM card, allowing users to connect to Wi-Fi and download VoIP applications or unlock the device, leading to unpaid services and the sale of unlocked devices on the black market.
Innovation Solution
Implementing a user equipment (UE) that disables Wi-Fi access if the SIM card is not activated, presenting the user with a graphical user interface (GUI) indicating that Wi-Fi access is disabled until the SIM card is activated, thereby requiring users to purchase and activate the SIM card before using the device's mobile services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Wi-Fi access is enabled without SIM card activation, then users can connect to Wi-Fi and use the device as a tablet, but users can download VoIP applications and unlock the device leading to unpaid services and black market sales
Solution Approach 1:
The system performs preliminary activation verification before enabling Wi-Fi access. The SIM card must be activated and associated with a payment account before the Wi-Fi radio is permitted to operate, preventing unauthorized usage before payment arrangement
Solution Approach 2:
The base station acts as an intermediary between the user equipment and the payment verification system. The base station receives activation status information from the payment account system and controls Wi-Fi access accordingly, mediating the connection between service provision and payment verification
2Reliability
If SIM card activation is required before Wi-Fi access, then service payment integrity is maintained, but users cannot use the device for basic functions without completing activation
Solution Approach 1:
The system requires preliminary SIM card activation and payment account association before enabling any device functions including Wi-Fi. This preliminary action ensures payment integrity is established before service delivery
Solution Approach 2:
The activation requirement applies universally to all device functions simultaneously. By making the SIM card activation a prerequisite for both cellular service and Wi-Fi access, the system creates a unified control mechanism that ensures payment integrity across all services
3Adaptability or versatility
If users can connect to Wi-Fi without activated SIM card, then device functionality is maintained, but mobile network operators cannot recoup subsidies
Solution Approach 1:
The base station and payment account system act as intermediaries to verify activation status before permitting Wi-Fi access. This intermediary control mechanism ensures that subsidy-provided devices are only activated when payment arrangements are in place, enabling operators to recoup subsidies
Solution Approach 2:
The system implements feedback control where the base station continuously monitors activation status and payment account information, and dynamically adjusts Wi-Fi access permissions based on this feedback. If activation is not confirmed, Wi-Fi access is denied, creating a closed-loop control system for subsidy protection

AI summary
Example embodiments relate to a user equipment that can receive a command to turn on the user equipment. In response to determining that the user equipment has not been initialized, and prior to displaying a graphical user interface listing a Wi-Fi network to which the user equipment can connect, the user equipment presents a graphical user interface that displays an option to activate a cellular service provided by a mobile network operator entity, but does not display an option to activate the cellular service at a subsequent time.
