Title:
IOT DEVICE CONNECTED TO SERVER VIA NAT, AND IOT COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/095957
Kind Code:
A1
Abstract:
Provided are an IoT device and an IoT communication method. The IoT device may: be connected to a server via NAT; execute a first session for service connection; and execute a second session for calculating a particular keep-alive value corresponding to a period in which an IP address mapped by the NAT expires. The present invention can minimize transmission of a keep-alive value of an IoT device, enables an IoT device to share a particular keep-alive value with other IoT devices, and thus can minimize a network load which may be caused by a keep-alive value of an IoT communication device.
