	abstract = {The 3rd Generation Partnership Project (3GPP) has
introduced the evolved Multimedia Broadcast/Multicast Service
(e-MBMS) feature for cellular systems as an evolution to the
existing MBMS service. To support e-MBMS in Long Term
Evolution (LTE) systems, 3GPP recommends the use of Point-to-
Multipoint (PTM) transmissions and MBMS over a Single
Frequency Network (MBSFN). MBSFN is a new feature where a
time-synchronized common waveform is transmitted from
multiple cells. In this paper we investigate the provision of
MBMS service over a combination of MBSFN and PTM
transmission methods. A cost analysis of the MBMS service is
presented based on the transmission cost over all the interfaces
and nodes of the LTE architecture. We evaluate the performance
of this transmission scheme from telecommunication cost
perspective and we compare it with other transmission schemes.
The performance evaluation has been performed with the aid of a
new simulation tool that estimates the cost for the MBMS
provision under different network topologies, MBSFN
deployments and user distributions.},
