Wireless communication system, relay station, user equipment, and wireless communication method

A relay station that relays a wireless signal sent and received between a base station and a user equipment, the relay station comprising:

• a processor that executes reconnection processing with the base station, every time a plurality of time durations with respect to certain timing elapse, for a call corresponding to each time duration;
• and
• a transmitter that, if the relay station is not capable of reconnecting with the base station until a predetermined time elapses after a start of the reconnection processing for the call corresponding to the each time duration, sends a message to the user equipment for notifying a call disconnection of the corresponding call in response to the lapse of the predetermined time.

A user equipment that sends and receives a wireless signal to and from a base station via a relay station, the user equipment comprising:

• a receiver that receives a message that is sent from the relay station, if the relay station is not capable of reconnecting with the base station until a predetermined time elapses after a start of reconnection processing, every time a plurality of time durations with respect to the certain timing elapse, for a call corresponding to each time duration, the message notifying a call disconnection in response to the lapse of the predetermined time;
• and
• a processor that executes call disconnection processing on the corresponding call in response to the message being received.
