3G Long Term Evolution is an all internet protocol 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 a long term evolution network. There is a major change in the way voice is transmitted in long term evolution network, in that it is transmitted in packets instead of through circuits.
