Abstract (en)

[origin: WO2007039494A1] The present invention provides a method for improving service performance of a trunk broadcasting service in a mobile communication system, characterized in that the method comprises the following steps: (1) transmitting the same trunk broadcasting service signal on at least two different frequencies in a local cell and/or adjacent cells; (2) receiving at least two corresponding trunk broadcasting service signals, respectively, via a diversity receiver of a user terminal; (3) combining said at least two received trunk broadcasting service signals, according to a predetermined diversity combining method, by said diversity receiver, to obtain a signal with a gain.
