Zusammenfassung:The invention relates to a method for providing an MBMS service in a wireless communications system comprising a mobile network (N) communicating over a radio air interface (Al) with a plurality of UEs (T1 to Tn) desiring to receive the MBMS service in a cell (CA), the method comprising the steps of: using a point to multipoint on a common channel transmission mode with a preset amount of transmission power (106); detecting if there are UEs in the cell (CA) which receive low MBMS service quality with said point to multipoint on a common channel transmission with a preset amount of transmission power set to a value less than the amount of transmission power needed to cover the whole cell area (108); and using ± point to point on dedicated channels transmission mode for such detected UEs receiving low MBMS service quality with said point to multipoint on ± common channel transmission with ± preset amount of transmission power (110).
