ABSTRACT:
A method is presented for enhancing pre-synchronization reliability in a cellular radio system. At least one base station in the cellular radio system is arranged to transmit at least two such transmissions (350, 351; 360, 361; 370, 371; 380, 381) that are usable for mobile stations in pre-synchronization. Said two transmissions are relatively close to each other in succession and they are timed to occur approximately at a time when there is a temporary idle period in an active communication connection between a mobile station and a base station.
