Abstract: Systems with support nodes (30) for transmitting multicast information to terminals (40) via radio networks controlled by radio network controllers (33) are provided with service detectors (54) for detecting multicast services supported by the radio networks and with contact instructors (55) for, in response to negative detection results, instructing the radio networks to contact the terminals (40) individually instead of contacting the terminals (34-39) as a group. Only radio network controllers (33) located in hotspot areas (81) need to be adapted to handle the multicast service. The terminals (40) comprise identifier selectors (43) for selecting access point identifiers to be sent to the support nodes (33) for identifying an individual bearer to be used for transmitting the multicast information, and identifier detectors (44) for detecting the access point identifier in a bearer set up message. The support nodes (33) further comprise identifier suppliers (56) for supplying the access point identifier received from the terminal (40) to the bearer set up message.
