Abstract
A method and system for providing a broadcast or multicast service to a terminal device in a data network, wherein a connection state of the terminal device is switched to a dedicated channel state in which a dedicated physical channel is allocated to the terminal device, in response to a broadcast service notification. Thereby, point-to-point connections can be used for data transmission of said broadcast or multicast service, without requiring any additional responses from the concerned terminal devices.
