In a wireless communications system, multicast messages are transported to
groups of wireless terminals by employing a common control channel to
transmit a multicast paging message indicating that multicast traffic
data is to be transmitted to a particular group of wireless terminals. In
an embodiment of the invention, the essential information transmitted in
the common control channel is the identifier of the group of wireless
terminals intended to receive the multicast traffic data and the location
of a traffic channel on which the multicast traffic is to be transported
in a channel resource which may include a representation of bandwidth and
time interval. In accordance with an aspect of the invention, the common
control channel is associated with a traffic channel in a prescribed
fixed manner. Further, the traffic channel used for the purpose of
multicast can be the same traffic channel used for the normal
point-to-point transmission of traffic data.
