Patent ID: 7885669

Claim:
A method for detecting paging indicators through a paging channel for removing a mobile terminal from an idle mode in a wireless communication system, the method comprising: receiving a first paging indicator (I 1 ); determining first and second threshold values (T 1 and T 2 respectively) based on a signal-to-noise ratio (SNR) of the first paging indicator with the first and second threshold values being different, given the SNR of the first paging indicator is below a predetermined initial SNR threshold; deriving a first paging indicator metric (x 1 ) corresponding to the first paging indicator; determining in a first stage whether the mobile terminal shall be removed from the idle mode based on comparisons between x 1 and T 1 and T 2 respectively; if it cannot be determined whether the mobile terminal shall be removed from the idle mode in the first stage, deriving a second paging indicator metric x 2 based on receiving a second paging indicator (I 2 ); and determining in a second stage whether the mobile terminal shall be removed from the idle mode based on a comparison between a third threshold T 3 and a predetermined function of x 1 and x 2 , wherein T 1 and T 2 are derived based on a square root of the SNR corresponding to the first paging indicator with T 1 indicating a boundary for tolerating a miss call and T 2 indicating a boundary for tolerating a false alarm, and T 3 is derived based on a square root of the SNR corresponding to the second paging indicator.
