In a satellite telecommunications system, a mobile user terminal (4a) selects the cell through which a communications channel is to be provided on the basis of power measurements on a BCCH broadcast channel associated with each cell. Inaccuracies associated with the power setting process can cause the user terminal to select a cell through which communications are not supportable. By increasing the transmitted BCCH power associated with the correct cell, through which communications are supportable, and decreasing the BCCH power in the erroneously selected cell, the user terminal is encouraged to make the correct choice. <IMAGE> |
