<p>In a frequency sharing method, IS-95 base station apparatuses and W-CDMA base station apparatuses are arranged in a one-to-one correspondence. The first base station transmission power value of the first base station apparatus is obtained in each frequency band in the IS-95 scheme. The second base station transmission power value of the second base station apparatus adjacent to the first base station apparatus is obtained. Whether there is a frequency band in the IS-95 scheme in which the sum of the first and second base station transmission power values is a predetermined threshold or more is determined. When there is a frequency band in the IS-95 scheme in which the sum is the predetermined threshold or more, a frequency handoff is performed to switch a communication channel in the IS-95 scheme which is using the frequency band in which the sum is not less than the predetermined threshold to another frequency band in the IS-95 scheme. An IS-95 base station apparatus, a mobile communication system, and a W-CDMA base station apparatus are also disclosed. <IMAGE></p> |
