3G Long Term Evolution (LTE) is an all internet protocol (IP) based network and one of its main aims is to improve mobile multimedia services. This is achieved through streamlining the system for packet services. This leads to improvements in the form of higher bit rates, lower latencies, and a variety of service offerings. However, more challenging technical difficulties may be expected to arise when voice traffic flows over an LTE network. There is a major change in the way voice is transmitted in LTE in that it is transmitted in packets instead of through circuits. This has led to the development of new types of resource management schemes, which are quite challenging. In this paper, we propose a new scheduling algorithm for voice traffic over LTE. This algorithm takes into account Voice over Internet Protocol (VoIP) parameters and shows, through simulations, an improvement in overall performance based on throughput and block error rate of up to 30 percent.
