A circuit arrangement for determining a mobile radio cell timing is provided. The circuit arrangement may include a receiver configured to receive a paging signal in accordance with a predetermined cell timing, and one or more synchronization signals, a receiver activating/deactivating circuit configured to activate the receiver for a predetermined time period to receive the paging signal in accordance with a previous paging signal cycle, and further configured to deactivate the receiver after the predetermined time period has lapsed, a cell detection circuit configured to execute during the predetermined time period a cell detection procedure using the one or more synchronization signals, thereby determining an updated cell timing, and a memory configured to store the updated cell timing.
