Device methods and for its conduct the channel switch in the fusion network of multiple communication systems

摘要

A method for performing a channel switch by user equipment of a first communication system in a network converging a plurality of communication systems may comprise the steps of receiving a channel switch command message, which includes a switch time and a new channel number, from a base station of the first communication system; transmitting a channel switch response message, which indicates acceptance of a channel switch when the new channel number is supported by the user equipment, to the base station of the first communication system as a response to the channel switch command message; receiving a channel switch notification message, which notifies of a channel switch, from a base station of the second communication system; and receiving data from the base station of the second communication system via a channel, which corresponds to the new channel number, based on the switch time and the new channel number, based on the switch time and the new channel number according to the channel switch notification message.
