Abstract :
With the evolution of wireless systems from traditional circuit switch technology to packet based technology there is a requirement that voice be maintained to an acceptable level of quality such that user experience does not become compromised. All next generation wireless networks have been specified as packet switched radio networks which imply that the flaws of traditional packet based networks now also apply to voice over the wireless medium. This combined with the dynamics of a traditional air interface provides a further challenge to voice over a packet switched wireless network. The following paper proposes the facilitation of regulation that will predefine the handover of Quality of Service (QoS) metrics for voice from one predefined QoS network domain to subsequent network domains for wireless system handover. It is the intention of this paper to highlight the advantages of providing a voice QoS regulated admission control, bearer / service flow selection and mobile transport backhaul so as to ensure the successful transmission of quality voice packets.
