Patent ID: 7826420

Claim:
A method of connecting a new device to be added to an existing centralized radio network (piconet) the network comprising a master device and at least one further device in the transmission range (Tx) of the network coordinator (PNC) at least one new device not being in the transmission range (Tx) of the network coordinator (PNC), the method comprising the steps of: a) the new device to be added to the network, not being in the transmission range (Tx) of the network coordinator (PNC), becoming a temporary network coordinator (tempPNC) which broadcasts a beacon with an initiation request in the beacon indicating that it intends to associate to an existing network (piconet); b) a device belonging to an existing network (piconet) that receives the beacon with the initiation request of the temporary network coordinator (tempPNC) optionally asks its own network coordinator (PNC) whether to become a child network coordinator (CPNC) and in case of positive answer or in case the optional request at the own PNC is not needed: transmitting a corresponding response signal indicating that it is an available child piconet coordinator (CPNC) to associate to; c) those devices that became a child network coordinator (CPNC) signalling a response to the initiation beacon in form of one or several broadcast or unicast frames indicating that they are available child piconet coordinators (CPNCs); d) the new device to be added to the network acting as a temporary network coordinator (tempPNC) scanning the channels or frequencies, receiving the response signals and choosing at least one of the available child network coordinators (CPNCs) as master; e) the new device to be added to the network acknowledging at least one of the selected child network coordinators' response signals and f) the new device to be added to the network terminating its role of acting as a temporary network coordinator (tempPNC) and becoming a slave with regard to the chosen child network coordinator (CPNC) that works as a coordinator.
