Abstract
The present invention relates to a method and system for performing a multicast transmission in a cellular network, wherein an identification information, which indicates terminal devices and/or areas in which authorized terminal devices are assumed to be located, is transmitted from a core network (100) to a radio access network of the cellular network by using a control information transmission protocol. Then, a signalling connection of a control and user data transmission protocol is establishing based on said identification information and used for transmitting multicast related data and corresponding control information between the core network (100) and the radio access network. Thereby, already defined protocol layers can be used for implementing multicast transmission, while modifications are minimized.
