Abstract:
1. A method of establishing and operating an ad hoc network including a plurality of cellular devices, said method comprising: receiving an incoming call at a first cellular device of the plurality of cellular devices in a radio signal transmitted by a cellular network transmitter; activating a second cellular device of the plurality of cellular devices to indicate the reception of the incoming call by use of a dedicated connection between the first cellular device and the second cellular device, wherein all other cellular devices of the plurality of cellular devices are also activated at substantially the same time to indicate the reception of the incoming call; receiving a request at the first cellular device by use of the dedicated connection from the second cellular device that the second cellular device be an answerer of the incoming call; establishing a connection to the incoming call by the first cellular device after the receipt of the request that the second cellular device be an answerer of the incoming call; and making the second cellular device an answerer of the incoming call by relaying speech packets intended for the first cellular device to the second cellular device, relaying speech packets from the second cellular device to the incoming call and relaying call control functions intended for the first cellular device to the second cellular device, wherein the relaying is performed by the first cellular device.
