New UPnP service for multimedia remote sharing with IMS framework

In this paper we describe a new service that allows multimedia sharing between UPnP terminals connected to remote networks. The service grants the confidentiality of users' contents since they are still stored in the home network. Our approach uses IP Multimedia Subsystem (IMS) framework to establish a secure HTTP session between remote devices. A new Remote Access Application Server is deployed in the IMS network to manage users' rights to access to remote homes. In the home network we define an UPnP Reverse Proxy component to control remote users' rights to access to contents in the home network. In addition, our service ensures the QoS during contents delivery based on the QoS support in the IMS framework.
