Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The base station acts as an intermediary to facilitate bootstrapping information exchange between IoT devices. The base station receives bootstrapping information from a first device, determines a second device to connect with, and sends the bootstrapping information to the second device, enabling efficient CIoT-based connection establishment without relying on traditional DPP methods

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the communication parameter from traditional DPP protocols (QR code, NFC, Wi-Fi aware, BLE) to CIoT-based communication protocols. This parameter change enables the use of cellular network resources for bootstrapping information transmission, significantly improving connection establishment efficiency and enabling large-scale IoT device deployment
