N2 - This paper reports on the quality of service (QoS) mapping mechanisms for converged OFDMA-PON and LTE networks to satisfy the stringent QoS requirements. Various options for exhibiting QoS mapping between the LTE bearers and optical OFDMA-PON queues have been presented. These include, wireless classes forwarded directly to one priority optical queue (so called non-mapping mechanism), 1:1 mapping where class identifier, QoS channel indicator (QCI), levels are mapped to their respective priority optical queues and finally group mapping taking into account bandwidth availability at both enhanced node Bs (eNBs) and optical network units (ONUs) to accommodate optical and wireless user's requests. Performance figures, based on system level simulation, are drawn with respect to the QCI delay between eNBs and evolved packet core (EPC) for various numbers of users per cell.
