A method and system is provided that supports minimizing handover times of netsurfing smartphones controlled by home Internet Access Devices (IADs) to shared IADs and optimizing earnings from these shared devices. The shared services are provisionable right at the handovers. Any shared IAD can implement an automatic auction of its service capacity controlled by a clearing system. The shared IADx automatically generates lucrative clicks on services of location based Internet-apps issued by Ayz passing through sharedIADx's reach. Several such provisioning systems may run concurrently, thus enabling high flexibility as to instant and local/regional system restructuring, e.g. on behalf of pricing strategy adaptations and/or version control. The application of the invention needs no change of the networks between which the above described pre-HO support of their HOs/MHOs shall be performed, i.e. it may work on top of all networks between which HOs or MHOs may be executed.
