The invention relates to a telecommunications method in which
multidestination information is transmitted from a terminal or from a
server to a plurality of destinations using a protocol of the same type
as the Internet Protocol (IP), and a control unit, such as a router, is
provided to detect the presence of at least one destination. One
destination or at most a limited number of destinations (72) is assigned
a group representative function. That destination periodically sends a
presence signal (62) to the control unit (54). The method can be used in
a satellite telecommunications system. It requires less signaling than
the IGMP.
