Paging indicator deciding method of mobile communication terminal
First Claim
Patent Images
1. A method for determining a paging indicator of a mobile terminal, comprising:
- comparing a ratio between a paging indicator SNR (Signal-to-Noise Ratio) estimate value and a pilot channel SNR estimate value with a threshold value;
variably setting the threshold value based on a SNR of the pilot channel; and
determining a probability distribution function based on a ratio between the paging indicator SNR estimate value and the pilot channel SNR estimate value,wherein the threshold value is determined so that a Miss Probability (MP) has a greatest value in a range that the MP does not exceed a maximum standard value.

Abstract
A paging indicator deciding method of a mobile communication terminal in which a threshold value for deciding a paging indicator is variably set according to a SNR of a pilot channel. If the SNR of the pilot channel is in a range that a false alarm rate (FAR) has a large value, the mobile terminal determines a threshold value so that it can have the greatest value in a range that a miss probability (MP) does not exceed the standard value. If the SNR of the pilot channel is not in the range that the SNR has the large value, the mobile terminal determines a threshold value to obtain the smallest MP in a range that the FAR is not further increased.
