<p>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.</p> |
