The invention relates to a method for providing multicast and/or broadcast
services to user terminals (8, 9) via a cellular network (2, 5). In order
to increase the efficiency of multicast or broadcast transmissions, it is
proposed that each of said user terminals (8, 9) willing to receive
content data of at least one multicast and/or broadcast service enters at
least once for a pre-determined time a state in which it is capable of
receiving content data of said multicast and/or broadcast service. The
invention equally relates to a corresponding user terminal, to a
corresponding cellular network and to a corresponding mobile radio
system.
