Abstract
In a mobile radio communication system, a mobile station has a field level decision section which outputs a decision signal when the electric field level of a received signal exceeds a threshold level. A controller sequentially sets a plurality of different threshold levels. In response to the decision signal from the decision section, synchronization to the received control signal begins. When the mobile station receives down-going control signals from a plurality of base stations, it selects the one having the highest field level, and then sets up synchronization to the signal selected.
