The evolved Multimedia Broadcast/Multicast Service (e-MBMS) feature is introduced by the 3rd Generation Partnership Project (3GPP) as a complement to the existing MBMS service in order to accommodate multicast groups that are interested in receiving the same data. MBMS service is provided by MBMS over a Single Frequency Network (MBSFN) and/or Point-To-Multipoint (PTM) transmission methods. One of the challenges of MBMS is the complete error recovery of the transmitted files, a matter of great importance since the distribution of binary data must result in 100% error-free download. To fulfill this tight requirement, Forward Error Correction (FEC) mechanism has been proposed by 3GPP. In this work, we investigate the reliable multicasting by introducing a transmission method that combines the advantages of MBSFN and PTM transmission methods. We compare several FEC-based file recovery methods and evaluate them against various network parameters in a realistic simulation environment. The comparison is based on a cost-oriented analysis of MBMS service that takes into account the transmission cost over all the interfaces and nodes of the LTE architecture. The simulation results are performed with the aid of a new simulation tool and show that the performance of the file repair schemes depend on the network configuration.

the 4th generation (4G) of radio technologies designed to increase
the capacity and speed of mobile communications. To support
Multimedia Broadcast/Multicast Services (MBMS), LTE offers
the possibility to transmit Multimedia Broadcast multicast
service over a Single Frequency Network (MBSFN), where a
time-synchronized common waveform is transmitted from
multiple cells for a given duration. In this paper we analytically
present the MBSFN delivery method and evaluate its
performance. The critical parameters of primary interest for the
evaluation of the scheme are the packet delivery cost and its
scalability. To this direction, a telecommunication cost analysis of
the MBMS service is presented based on the transmission cost
over the air interface, as well as the costs of all interfaces and
nodes of the MBSFN architecture. Since the performance of the
MBSFN scheme mainly depends on the configuration of the LTE
network that is under investigation, we consider different
network topologies, MBSFN deployments and user distributions.10aCost analysis10aLTE10aMBSFN1 aBouras, Christos1 aAlexiou, Antonios1 aKokkinos, Vasileios1 aTsichritzis, George  uhttp://telematics.upatras.gr/telematics/publications/communication-cost-analysis-mbsfn-lte?language=en01774nas a2200193   4500008004100000245008200041210006900123300001700192520108500209653001801294653000901312653001801321653000901339100002101348700002201369700002401391700002201415856014301437       2009                        eng d00aCost Analysis and Efficient Radio Bearer Selection for Multicasting over UMTS0 aCost Analysis and Efficient Radio Bearer Selection for Multicast  a 1159 - 11723 aAlong with the widespread deployment of the Third Generation (3G) cellular networks, the fast-improving
