Performance Gains of Network Coding in Evolved 3G Mobile Network for MBMS

Abstract—3GPP has defined a Multimedia Broadcast and
Multicast Service (MBMS), which is a major enhancement in the
downlink of the 3G standard. The focus of MBMS is on the
efficient management of radio and core network resources while
reusing as much existing functionality as possible. On the other
hand, Network Coding has been proved that can achieve the
throughput capacity of an arbitrary multicast session by allowing
intermediate nodes encode the incoming packets before forward.
In this paper, we focus on the performance of random network
coding for MBMS in evolved 3G mobile network. Basis on the
architecture of multiple cell service of MBMS, we propose a
multicast scheme using random network coding (RNCM). In this
scheme, we integrate the capability of random network coding
and the several service channel provided by the Base Stations
(BS) in a MBMS cell. The simulation results show that RNCM
scheme can increase the throughput of network significantly.
