Policy-based QoS control for open services in BcN

Recently, 3GPP introduced IMS-specific QoS mechanisms and service-based local policy control to support QoS-enabled services including VoIP. The IMS architecture is evolving to a more generic QoS and policy framework to simplify the introduction of new services and to implement service-based control of the access for a whole range of services. In this paper, we proposed the QoS control API for 3 party service provider to demand the required bandwidth onto network operators policy server. Also, QoS control scenario is described to support the video on demand service
