Abstract: A user terminal receives at least one signal with information depending on a location of the user terminal. The user terminal processes the at least one signal for providing data related to the location while it is in a cell of an accessible private base station and saves the data as a reference data. After that, the user terminal receives at least one signal with information depending on the location of the user terminal and a broadcast from a private base station. The user terminal processes the at least one signal for providing data related to a location of the user terminal and compares the data and a reference data with each other. The controller enables a contact to the private base station if the data and the reference data match each other and, otherwise, disables a contact to the private base station.
