We correct the error in using the Allocation and Retention Priority (ARP) parameter defined in 3GPP T.S.3GPP 23.203 (2013). In our paper (Ivesic et al., 2014) the parameter was used in the admission control algorithm in a way that contradicts its specified purpose. In this corrigendum we present the corrected version of the algorithm, the necessary changes to the original text in algorithm definition,...
The problem of dynamic Quality of Service (QoS) management for multimedia services has been addressed from two complementary, yet interrelated directions; one mainly dealing with designing adaptive or “elastic” services, and the other, dealing with “smarter” resource allocation. We adopt this approach in this paper, by performing a graceful quality degradation and the corresponding resource (re)allocation...
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...
