Title:
METHOD FOR DATA TRANSMISSION AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/164483
Kind Code:
A1
Abstract:
Disclosed are a method for data transmission and a device, used to solve the problem in the prior art of interruption of information transmission between nodes when a user terminal node suddenly fails in a body area network. In embodiments of the present invention, when a user terminal node is about to fail or energy is about to run out, the user terminal node sends dedicated signaling to a wireless access node to indicate that the user terminal node is about to fail or the energy is about to run out, and then a new connection is established between the wireless access node and a body device node connected to the user terminal node to enable data transmission between the wireless access node and the body device node, so that when the user terminal node fails or the energy runs out, information transmission between the nodes will continue to improve the information transmission rate.
