NETWORK DEVICE AND DATA COMMUNICATION METHOD FOR EMERGENCY TRAFFIC USING COGNITIVE PILOT CHANNEL

摘要

PURPOSE: An emergency network device and a data communications method are provided to process the communications of the terminal using a pilot channel, in case the communications of the terminal is impossible by using the RAT(Radio Access Technology). CONSTITUTION: A determining unit(510) monitors whether RAT of a wireless network normally operates or not. A time slot assignment circuit(520) assigns a cognitive pilot channel to the terminal according to the control function of the determining unit. A data communications part(530) processes the data communications through the cognitive pilot channel with the terminal. The data communications part transmits or receives the voice and the image through the terminal.
