Abstract
A method in a radio telecommunications network of broadcasting data in an over-the-air multicast to a group of mobile terminals. Statistics from regular point-to-point cellular transmissions to build a statistical database for each base station. The statistical data indicate the optimal signal quality that users normally experience when operating in that cell. From this data, a minimum transmission quality (TQmin) that a mobile terminal must receive for the type of data being broadcast is determined. The method then broadcasts a test transmission to the mobile terminals, and includes a maximum transmission quality (TQmax) in order to limit the number of responses. A response is then received from a mobile terminal representative of the group, the response including an indication of the received transmission quality. The method then determines whether the received transmission quality was greater than or equal to TQmin. If the received transmission quality was greater than or equal to TQmin, the data is broadcast in the over-the-air multicast to the group of mobile terminals.
