Abstract

With the booming of multimedia services, the 3rd
Generation Partnership Project (3GPP) has introduced the
evolved Multimedia Multicast/Broadcast Service (e-MBMS)
feature for LTE systems. The main objective of MBMS is to
introduce real broadcast distribution capabilities into cellular
systems. This purposed 3GPP to introduce the MBMS over a
Single Frequency Network (MBSFN) operation. In this work
we investigate the provision of MBMS service over a
combination of MBSFN and PTM transmission schemes. We
focus on the file repair procedure, because the distribution of
binary data via MBMS must result in 100% error-free
downloaded files. In order to achieve this goal, MBMS offers a
Forward Error Correction (FEC) mechanism. Our simulation
results show that there are some file repair schemes that
achieve better performance as far as different network
configurations are concerned. Furthermore, we compare all
the file recovery methods and evaluate them against various
network parameters in a realistic simulation environment.
