Abstract: A docking station provides fixed mobile convergence and includes a docking interface for a communication unit, a transceiver for a fixed packet network, and/or a telephone interface to a public switched telephone network (PSTN) telephone. The method includes detecting if the communication unit, fixed packet network, and/or PSTN telephone is connected. If the fixed packet network is available and the communication unit connected, a connection is established between the two in response to a call initiated/received at the communication unit; packets are transferred so that calls on the communication unit are conducted over the fixed packet network. If the PSTN telephone and the communication unit are connected, a connection is established between the two in response to a call initiated at the PSTN telephone or received at the communication unit; protocols are interworked to permit calls placed/received on the PSTN telephone to be conducted over the cellular network.
