Abstract:
1. A method comprising: in a radio system comprising at least two core networks including a first core network and a second core network, where the first core network comprises at least one public base station and a base station controller, where the second core network comprises a private base station configured to wirelessly communicate with a user terminal via a first channel of communication, the core networks at least partially providing a second channel of communication between the private base station and the at least one public base station separate and independent of the first channel of communication; measuring, by the user terminal and/or the private base station, a travel time depending on a propagation delay between the private base station and the user terminal; signaling data on the travel time to the first core network of the radio system via the second channel of communication; and sending a control data from the first core network to the private base station of the second core network via the second channel of communication and decreasing transmission power of the private base station in the second core network if the measured travel time is longer than a predetermined reference time.
