Mobile station evaluates power of signals received and compares it with threshold value and also identifies base stations whose signal power in reception exceeds first threshold value and transfers signal indicating base stations identified as those suited to be included in group of active stations to controller. Measured energy of each check signal is subjected to iterative comparison with threshold value generated in compliance with total energy of check signals out of group of active stations. If most powerful check signal meets this threshold value, it is added to modified group of active stations. Second iterative process is used to take decision on whether check signal should be removed from modified group of active stations. Mobile station takes decision on whether group of active stations used at present should be modified and dynamically corrects desired threshold values.
