In a method for multicast service continuity in a radio communications system, each radio network controller has a first identifier of each multicast service whose activation was previously requested by at least one radio terminal ( 1, 11 ) via said radio network controller and is adapted to notify radio terminals in a corresponding coverage area of the start of at least one session relating to one of said multicast services, reported by a core network, said notification incorporating the first identifier of said service. With respect to a radio terminal ( 11 ) entering the coverage area of a drift radio network controller ( 15 ) after having been in the coverage area of a serving radio network controller ( 14 ), the radio terminal having previously requested activation of a multicast service via the serving radio network controller, the first identifier of said service is sent from the serving radio network controller to the drift radio network controller.
