A framework for elastic QoS provisioning in the cdma2000 1×EV-DV packet core network

With the fast proliferation of QoS-enabled wireless packet networks, the need for effective QoS control is increasing. In this article, we focus on QoS provisioning in the cdma2000 1× evolution for high-speed integrated data and voice (1×EV-DV) packet core network. We investigate a dynamic bandwidth provisioning method that is able to increase a service provider´s revenue. It is achieved by releasing unutilized bandwidth for use by other profitable services. The proposed method is implemented as an SNMP-compliant management information base and deployed at the packet data serving node. The experiments conducted on the LG Telecom 1×EV-DV testbed show that the method can increase the bandwidth for the conversational class and guarantee adequate service quality for the background class as well.
