Handover method used in a wireless communication system

A wireless communication system for a mobile device to communicate the wireless communication system, the system comprising:

• a first base station emitting a first signal, the mobile device initially communicating with the first base station;
• and
• a second base station emitting a second signal;
• wherein the mobile device measuring a first power level of the first signal and a second power level of the second signal and generating an equivalent signal power level if the first signal power level is substantially equal to the second power, the mobile device generating a handover power level according to the equivalent signal power level, the handover power level ranging between the equivalent signal power level and a predetermined power level, the mobile device handing over to the second base station when the power level of the first signal measured by the mobile device is equal to the handover power value.
