Method for performing channel switch in network converging plurality of communication systems and apparatus for same
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 receiving, a channel switch command message including a switch time and a new channel number, from a base station of the first communication system; transmitting a channel switch response message indicating 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 in 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 corresponding to the new channel number based on the switch time and the new channel number according to the channel switch notification message.
1. A method for performing channel switch by a user equipment (UE) of a first communication system, the method comprising:
receiving data from an access point (AP) of a wireless LAN (WLAN) through a channel of the AP;
receiving, a first message including a channel switch time and a new channel number of the AP, from a base station of a cellular communication system;
if the new channel number is supported by the user equipment supports, transmitting a second message indicating acceptance of the channel switch to the base station of the cellular communication system in a response to the first message;
receiving a third message notifying the channel switch from the AP; and
after receiving the third message, transmitting data to the base station of the cellular communication system until the channel switch time; and
transmitting data to the AP through a new channel corresponding to the new channel number after the channel switch time.
2. The method according to claim 1 , wherein the channel switch is determined by the AP or the cellular communication system.
3. The method according to claim 1 , wherein the first message comprises a channel switch command message.
4. The method according to claim 1 , wherein the second message comprises a channel switch response message.
5. A user equipment (UE) of a cellular communication system for performing channel switch, the UE comprising:
a receiver that:
receives data from an access point (AP) of a wireless LAN (WLAN) through a channel of the AP;
receives, a first message including a channel switch time and a new channel number of the AP, from a base station of the cellular communication system; and
a transmitter that:
if the new channel number is supported by the user equipment, transmits a second message indicating acceptance of the channel switch to the base station (BS) of the cellular communication system in a response to the first message,
wherein the receiver further:
receives a third message notifying the channel switch from the AP, and
wherein the transmitter further:
after the third message is received, transmits data to the base station of the cellular communication system until the channel switch time; and
transmits data to the AP through a new channel corresponding to the new channel number after the channel switch time.
