摘要：Long Term Evolution (LTE) technology supports only packet based services. To facilitate better Quality of Service (QoS) for Voice packets, LTE has resorted to Circuit Switched Fallback (CSFB) approach to deliver voice services. However, the CSFB scheme has many disadvantages whichare discussed in detail in the later stages of the paper. In this paper, we propose a scheduling scheme with voice enhancement for effective delivery of voice services in LTE. The proposed scheme uses packet switching unlike the CSFB scheme which uses circuit switching to guarantee delivery of voice services, thereby, providing the network with the flexibility of resource allocation that is provided in the packet switching. Apart, the simulation results have demonstrated that the proposed scheme was able to achieve the same QoS delivery provided by the CSFB approach.
