Abstract
A broadcast channel, such as a broadcast control channel that carries a short message service, in a GSM/EDGE or similar communication system can be extended with additional timeslots. These additional timeslots can be pointed out in a tree structure, the root of which is in the SMS broadcast channel. The extended broadcast channel can be used for broadcast-like services provided under a multimedia broadcast/multicast service.
