Requirements for an IMS-based Quadruple Play Service Architecture

摘要

Quadruple play can be understood as the provisioning of high-speed voice, video (live broadcast or on demand services, such as video on demand), and data services over broadband connections with mobility support. Currently, there are several trials of the IP multimedia subsystem deployed worldwide that promise to provide telecommunication and advanced multimedia services. This article focuses mainly on the basic requirements of a cooperative service delivery platform for provisioning quadruple play services. As a result of this research, an IMS-based cooperative service delivery platform is presented. This supports various access technologies to acquire the streaming services. To validate our quadruple play architecture, we implemented a prototype based on DVB-H and UMTS as the access technologies. This prototype is part of the ongoing development of the proposed architecture
