ABSTRACT:
Embodiments of the disclosed invention include a system and method for providing end to end quality of service for cellular voice traffic over a data network. For example, in one embodiment, the method includes tagging outgoing cellular traffic at a network interface device with a prioritization marking to produce prioritized data and transmitting the prioritized data directly to an access carrier network associated with providing an access line to the cellular network interface device. The method maintains, at the access carrier network, the prioritization marking of the outgoing cellular traffic for routing the outgoing cellular traffic through the access carrier network. The method hands off the prioritized data directly to a cellular service provider network associated with the cellular device via a directly connected network to network interface.
