Abstract
A communication system includes a first base station for communicating complying with a first communication protocol, a second base station for communicating by using radio frames complying with a second communication protocol and transmitting synchronization signals complying with the first communication protocol, the synchronization signals synchronizing the transmitted radio frames, and a mobile terminal for communicating according to the process includes: receiving the synchronization signals from the second base station while communicating with the first base station, estimating transmitting timing of the radio frames including symbols on the basis of the received synchronization signals, measuring a receiving signal strength of the symbol on the basis of the estimated timing, and controlling a handover from the first base station to the second base station on the basis of the measurement result by the measurement of the receiving signal strength of the symbol.
