FIELD: information technologies.
SUBSTANCE: for the purpose of access to first communication system, terminal determines time of transmission of access attempt, expected time of system response and secure time period, on the basis of transmission time and/or expected time of response, terminal determines point of start time for transmission of access attempt in such a way that secure time period not to overlap with tuning interval in which terminal should control another frequency. This point of start time may be set initially to the end of previous access attempt plus pseudo-random wait state and may be moved back or forth in time if required for time period chosen considering secure period.
EFFECT: possibility of access to first communication system and tuning to second communication system in certain time periods.
