Abstract

In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device requests association with the network and the central controller does not support the profile of the new device. A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller passes the control functionality to the controller-capable device, which becomes the new central controller. Thus it is possible to associate the new device with the net work. The invention allows to integrate devices supporting different profiles into a common network.
