Provided is a handset comprising a transceiver transmitting and receiving data to and from a base, a data error detector determining whether or not there is an error in the data received by the transceiver, and a reception duration controller changing a specific reception duration. If the data error detector determines that there is an error, then the reception duration controller extends a reception duration of the transceiver so as to receive the data newly sent from the base and to reduce unnecessary calling repetitions between the base and the handset and reduce wasted waiting time.
