In Universal Mobile Telecommunication System
(UMTS), the downlink capacity is limited by the base station
transmission power. Therefore, power control plays an important
role to minimize the transmitted power shared among unicast and
multicast users within a cell. In Multimedia Broadcast/Multicast
Service (MBMS), power control targets to the efficient utilization
of radio and network resources. However, the expected high
demand for such services stresses the need for an efficient
scheme, capable of dynamically allocating radio resources to
parallel MBMS sessions. This paper proposes a power control
mechanism for efficient MBMS session assignment in next
generation UMTS networks. The mechanism shares efficiently the
available power resources of UMTS base stations to MBMS
sessions running in the network. Furthermore, the mechanism is
evaluated through several realistic scenarios and the results
indicate the ability of the mechanism to utilize efficiently the
radio resources and to ensure the service continuity when parallel
MBMS services running in the network.
