NFC Terminal Role Classification for Network Configuration

The patent applies local quality by differentiating the roles of NFC terminals based on their specific properties. Each terminal is classified as either a host or router according to its energy level, MTU, and connectivity characteristics. This localized role assignment optimizes communication performance within the independent network by ensuring that terminals with higher capabilities serve as routers while those with lower capabilities function as hosts, thereby resolving the contradiction between network autonomy and communication performance.

The patent utilizes parameter changes by dynamically classifying NFC terminals based on their energy levels, MTU values, and connectivity status. Terminals with higher residual energy levels are designated as routers, while those with lower energy levels become hosts. This parameter-based classification ensures that energy consumption is optimized across the network, as routers with sufficient energy handle the additional processing burden while conserving energy for terminals with limited capacity, thus resolving the contradiction between network adaptability and energy consumption.

The patent applies preliminary action by performing role classification during the connection initialization phase, before actual data transmission begins. The LLCP layer exchanges classification information between NFC terminals during this initial connection setup, allowing roles to be determined in advance based on energy levels, MTU, and connectivity properties. This preliminary classification eliminates the need for complex real-time decision-making during data transmission, thereby resolving the contradiction between network optimization and classification complexity.

The patent merges the role classification process with the existing LLCP connection initialization procedure. Instead of implementing a separate classification mechanism that would increase initialization time, the patent integrates classification information exchange into the standard LLCP connection setup. The LLCP layer simultaneously establishes the connection and transfers the necessary classification data (energy level, MTU, connectivity status), allowing accurate role classification without adding significant initialization overhead, thus resolving the contradiction between classification accuracy and initialization time.
