Ad-hoc established device network
First Claim
1. A method for associating a new device with an ad-hoc established device network comprising a central controller and a set of terminal devices, comprising:
- checking whether the central controller supports a transmission profile of a new device which requests association, wherein the transmission profile indicates all transmission and connection related parameters that are mandatory for the new device;
in case the transmission profile of the new device is not supported, searching a database for a terminal device which is capable of acting as a controller and which supports both transmission profiles of the set of terminal devices and the transmission profile of the new device;
in case at least one such terminal device is found, performing a handover of a control functionality in order to establish said terminal device as the new central controller.

Abstract
In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device (15) requests association with the network and the central controller (16) does not support the profile of the new device (15). 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 (16) passes the control functionality to the controller-capable device (17), which becomes the new central controller (24). Thus it is possible to associate the new device (15) with the network. The invention allows to integrate devices supporting different profiles into a common network.

14. A central controller for controlling a set of terminal devices in an ad-hoc established device network, comprising:
-
a database configured to store information about the controller capability of said terminal devices, and about the transmission profiles supported by said terminal devices, wherein the information about the transmission profiles indicates all transmission and connection related parameters that are mandatory for the terminal devices, a checking unit configured to check whether the central controller supports the transmission profile of a new terminal device which is to be associated with the network, and for searching said database for a terminal device which is capable of acting as a controller and which supports both the transmission profiles of the network devices and the transmission profile of the new device, a handover unit configured to perform a handover of the control functionality to a controller-capable terminal device in case the central controller is not capable of supporting the transmission profile of said new terminal device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
