Abstract
The Quality of Service (QoS) mapping in Internet Protocol (IP) based networks is not well-suited for complex multimedia services in a dynamically changing service environment and service adaptation driven by such changes. The work presented in this paper is motivated by the challenge to utilize additional knowledge about the service and its adaptation capabilities, in form of the Media Degradation Path, in the signaling across Diameter interfaces related to resources authorization within the Third Generation Partnership Project (3GPP) IP Multimedia Subsystem (IMS). The proposed approach extends the functionality of current Diameter Rx and Gx applications in IMS, and illustrates it by using an adaptive video call service as an example.
