1. A method for provision of multicast and/or broadcast services in a mobile communications network which comprises a radio network and a core network, comprising:
transmitting multicast data for a multicast service through a single radio signal to a plurality of mobile communication units, wherein the multicast service is activated by at least one mobile communication unit, and/or broadcast data for a broadcast service which is configured by the at least one mobile communication unit, from a data source to the at least one mobile communication unit via at least one communication node, which is arranged in the core network, using a service-specific first context which is stored in the communication node and supports service transmissions to the plurality of mobile communication units;
in the case of a multicast service, controlling and monitoring of the transmission of the multicast data to the at least one mobile communication unit through the at least one communication node using a second context which is stored in the communication node and is specific for precisely that at least one mobile communication unit with reference to the activated multicast service in the communication unit; and
in the case of a broadcasting service, broadcasting of the broadcast data for the configured broadcast service in a region determined by the data source.
