Abstract
The present invention time and frequency synchronizes a plurality of private radio base stations operating in the coverage area of a land mobile communications network. The mobile network's control channels are used to derive a reference signal. A mobile terminal uses the reference signal to become synchronized both in time and frequency with the mobile network. Any of the private radio base stations that is linked in a traffic connection with the mobile terminal is synchronized with the mobile terminal. Consequently, the private radio base stations are indirectly synchronized with each other and also with the mobile communications network.
