In this work we present a model for online charging of media-rich services supporting dynamic QoS negotiation, within the third generation partnership project (3GPP) IP multimedia subsystem (IMS) emulated environment. In the QoS negotiation process a user, a network provider, and a service provider negotiate about the session to be initiated, resulting in an user-specific combination of media components...
As the next generation networks promise to provide network convergence with services for both static and mobile networks, the recent research focus is converging in the direction of standardizing common infrastructure based on all-IP networks. IMS is a recent initiative, designed by 3GPP and TISPAN partnership, which outlines a service delivery platform (SDP) framework. A flexible and robust QoS management...
The Internet has experienced tremendous expansion in the past several years. Demands for IP multimedia services are emerging. The third-generation (3G) wireless networks aim to support mobile users with numerous Internet services. 3G standards organizations are developing IP multimedia subsystems (IMS) to achieve seamless integration between Internet and 3G networks. Moreover, the collaboration between...
