Executive Summary

Multimedia Broadcast Multicast Services (MBMS), introduced by Third Generation Partnership Project (3GPP) in Universal Mobile Telecommunications System (UMTS) Release 6 specification, have the aim to support downlink streaming and game services to groups of users. MBMS can supply users with resources in two different modalities: Point-to-Point (PtP) and Point-to-Multipoint (PtM). The power consumed by the network is an important topic to discuss when considering the presence of MBMS services. The UMTS system is, in fact, interference-limited; thus, the power available to Node B is limited and it must be enough to serve any user under its coverage.
