Abstract

Current subscribers except optimal QoS for their real-time services, both under fixed and mobile access scenarios. These expectations demand complex QoS mechanisms and flexible mobility management from the network to provide a smooth service to the user. This paper provides a bottom up survey of the QoS and mobility mechanisms from the WiMAX air interface over the network architecture up to the interworking with the 3GPP network. The analysis includes aspects on mobility, QoS and security as far as it is relevant for mobility and QoS.
