A multimedia broadcast/multicast service (MBMS) in a universal mobile
telecommunications system (UMTS) includes a UTRAN that provides an MBMS
service. The MBMS service-related information is exchanged between the
UTRAN and a terminal or between nodes in the UTRAN by using an MBMS
identification so that a user group receiving MBMS data or a data of a
specific MBMS service can be identified.
