Abstract: Virtual home environment (VHE) becomes a hotspot as a way to provide service in the future heterogeneous network. According to the requirements and features of VHE, this paper proposes a system architecture to realize this concept based on SIP. Then service provision and some mechanisms for supporting VHE in this architecture are introduced. How to realize it based on SIP is discussed.
