One of the major prerequisites for Long Term Evolution (LTE) networks
is the mass provision of multimedia services to mobile users. To this end,
Evolved - Multimedia Broadcast/Multicast Service (E-MBMS) is envisaged to
play an instrumental role during LTE standardization process and ensure LTE?s
proliferation in mobile market. E-MBMS targets at the economic delivery, in
terms of power and spectral efficiency, of multimedia data from a single source
entity to multiple destinations. This paper proposes a novel mechanism for efficient
radio bearer selection during E-MBMS transmissions in LTE networks.
The proposed mechanism is based on the concept of transport channels combination
in any cell of the network. Most significantly, the mechanism manages to
efficiently deliver multiple E-MBMS sessions. The performance of the proposed
mechanism is evaluated and compared with several radio bearer selection
mechanisms in order to highlight the enhancements that it provides.
