Abstract

Universal Plug and Play (UPnP) consists of a set of protocols that allow consumer electronic (CE) devices to discover, connect and access one another when they are on the same sub-network. However, UPnP does not provide support for device mobility in which devices are allowed to move from one IP networking domain to another without affecting their ability to interact with other devices. In this paper we propose a system level architecture to provide mobility support to UPnP devices and services by utilizing Session Initiation Protocol (SIP). We propose a new UPnP mime type for carrying UPnP data. We also propose a UPnP packet message forwarding architecture, which uses SIP signaling procedures and hides the mobility of UPnP capable devices from other devices in a network.
