Abstract

In a satellite communications system, where a user terminal 34 may wish to page more than one satellite 10 or more than one spot beam 30, and where the definition of a timeslot 38 for a paging channel 48 occurs a predetermined period after the sending of a broadcast burst 42, the possibility of sustained temporal collision between paging channels 48 between adjacent satellites 10 or adjacent spot beams 30 is avoided by periodically, progressively, and cyclically, moving the predetermined period.
