Application: Data collection device, sensor terminal, metadata collection system, metadata collection method, and program (Patent ID: US20240089712A1)

The patent filed by Nippon Telegraph and Telephone Corp. describes a data collection device and method aimed at reducing the load on IoT terminals in terms of metadata transmission and power consumption. The invention involves a controller on the data collection side that instructs IoT terminals to reduce the transmission frequency of non-real-time metadata based on sensor type or other factors. This results in metadata being transmitted only at specific times permitted by the controller, thereby reducing transmission load and power consumption.

The claims associated with the patent detail the configuration of the data collection device and sensor terminal. The data collection device's controller indicates transmission frequencies for different types of metadata to the sensor terminal, allowing for differentiated transmission frequencies based on metadata types. The sensor terminal's transmitter adjusts transmission frequency based on the data collection device's instructions, discarding metadata that fails to transmit. The method outlined in the patent involves indicating transmission frequencies to the sensor terminal based on metadata types and adjusting transmission frequency accordingly. Additionally, there are provisions for not indicating transmission frequency for a certain period of time to the sensor terminal. Overall, the patent focuses on optimizing metadata transmission in IoT systems to reduce load and power consumption.
