Abstract:
1. A mobile station designed to send or receive at least a control channel using a given frequency in a first operating mode and to tune to a frequency different from the given frequency and perform a neighboring cell search in a second operating mode, the mobile station comprising: a measuring unit configured to obtain a measurement of radio channel quality at a measurement interval; a determining unit configured to compare the measurement and a threshold and to select one of the first operating mode and the second operating mode based on the result of comparison; and a preventing unit configured to prevent reporting of the measurement to a base station if the measurement is lower than the threshold, wherein the operating mode is selected based on the status of a buffer for storing data if the measurement of radio channel quality is lower than the threshold; wherein the mobile station is configured to switch from a regular mode to an irregular mode if a mean value of instantaneous measurements of radio channel quality is lower than a first threshold; and wherein the mobile station is configured to switch from the irregular mode to the regular mode if the mean value of the instantaneous measurements of radio channel quality is higher than a second threshold.
