摘要：
The present invention discloses a method of idle mode control in an orthogonal frequency-division multiplexing (OFDM) system. By superposing idle mode control channels on a frame synchronization pattern in the frame header of an OFDM frame, mobile terminals at a low migration rate will be switched into idle mode during packet service transmission intermission period. The mobile terminals in idle mode needn't do FFT to check whether there is any packet to be received after receiving every frame, thereby the power energy of the mobile terminals is greatly saved.
