Abstract

Multicast transmission is one of the major goals for Universal Mobile
Telecommunication System (UMTS) that motivated the 3rd Generation Partnership
Project (3GPP) to launch the Multimedia Broadcast/Multicast Service (MBMS)
framework. MBMS constitutes a significant step towards the so-called Mobile
Broadband, since it allows the efficient utilization of network and radio resources.
One of most important problems that MBMS is currently facing is the assignment
of the appropriate transport channel for the transmission of MBMS data. This
paper proposes an alternative solution to this problem, by introducing a cost-based
scheme for the efficient radio bearer selection that minimizes the overall delivery
cost. Our approach, calculates the telecommunication cost over the most crucial
interfaces of UMTS; and based on this cost selects the appropriate radio bearer.
