QoS signalling in IP multimedia subsystem of UMTS
In this paper, one example of providing end-to-end QoS for audio and video session between two UMTS user equipments when DiffServ is integrated in IMS transport layer is presented.

Methodology of provisioning QoS (Quality of Service) in DiffServ based IP network is presented and the effect on queuing delays and jitter of both traffic types when their WFQ weights vary and derive and optimal weights that provide the best overall delay and jitters for real-time traffic.

Advanced infrastructure — based streaming media overlay networks
A media overlay can enable new media capabilities in the network, while improving the end-user media performance and the system-wide efficiency of the network for both its media and non-media traffic.
Fairness of scheduling algorithms for real-time UMTS traffic in case of IP link congestion
Evaluation results of a simulation based study on the fairness of traffic scheduling algorithms for UMTS real time traffic that passes through UMTS core network and external IP backbone network, based on DiffServ are presented.
Comparative Analysis of Scheduling Algorithms for UMTS Traffic in Case of DiffServ Network Congestion
This paper proposes using of Low Latency Queuing (LLQ) scheduler, with the main idea of mapping voice and video telephony in two different QoS classes and virtual queues, but at the same time using Priority Queuing within LLQ for both voice andVideo telephony over all other QS classes.
