Abstract
A method, system, and business model are disclosed for supporting handover between a mobile host and a corresponding node located in a heterogeneous network. Handover paths are established to accommodate a plurality of quality of service properties. Admission control is performed that considers the established handover paths and an established first reservation path. Gateways are contacted to determine a handover path to use. The determined handover path is used to support vertical handover. A second reservation path is established while maintaining the first reservation path and the handover path.
