A wireless network and associated method for providing continuous communication service for a mobile unit as it roams within a virtual wireless network. The virtual network includes home and foreign access controllers and a virtual network manager (VN manager). The VN manager is used to maintain a VN configuration record that includes all active access controllers within virtual network and to disseminate said VN configuration record to all active access controllers. A tunneling data communication connection is established between all active access controllers including home and foreign access controllers. When a mobile unit first connects to home access controller and then roams to foreign access controller, communication data is transmitted between the mobile unit and the foreign access controller to provide continuous data communication on the basis of the characteristics defined by the virtual networking services while simultaneously preserving the IP configuration of mobile unit on the network.
