Abstract

This paper presents a framework on providing adaptive multimedia services across heterogeneous wireless access networks using the IP Multimedia Subsystem (IMS) subsystem. The adaptation is performed at the MRF function when the user performs a vertical handoff so that the service is adapted to meet the wireless bandwidth constraints. This paper describes how this adaptation experience can be implemented over a hybrid 3G and WLAN network through the IMS. The performance analysis of the proposed framework demonstrates the level of adaptation as well as signaling overhead required to stress MRF in order to perform video adaptation.

Keywords: IMS video streaming seamless vertical handoff multimedia provisioning
