Abstract:

New functions embedded in the access architecture are described to improve the deployment and Quality of Experience (QoE) of multimedia services. After definition of QoE and flow concept, generic enablers for monitoring and deep packet inspection are introduced. Distribution of Session Border Controller functions is proposed for a more scalable and secure deployment of conversational multimedia service. Methods for lawful interception are analysed. Two approaches to improve the QoE of video services, Forward Error Correction and retransmissions, are compared.
