VHE(virtual home environment) is an important concept for the 3rd gen eration mobile communication networks, which enables PSE(personal service environment) mobility across network boundaries and between terminals. A service-oriented VHE platform, WSEVHEP(Web services enabled VHE platform), was presented, which leverages Web services techniqu es for its architecture. The system requirements of WSEVHEP were discussed. A framework for service provisioning was proposed, in which the platform itself and the 3rd-party services were all published as Web services. Service work flows, such as service discovering, subscribing and executing, were all advanced. The platform realizes the concept of VHE features and satisfies the mobility requirements of users. It is useful to develop VHE platform on mobile Internet.
