Apparatus, and an associated method, for facilitating formation of a
RANcast in a radio communication system. An identifier identifies when a
selected number of mobile user endpoints within a cell of a radio
communication system are to receive the same multicast data. When the
number exceeds a selected threshold, a RANcast is implemented by a
RANcast implementer in which a common channel is used to broadcast the
multicast data to all the mobile user endpoints.
