Abstract:
1. A call pickup/forwarding method comprising: determining whether a first terminal is in voice/video communication with a second terminal upon receiving a call signal for call setup to the second terminal from the first terminal via a first network and upon receiving a request signal for pickup of a call received to the second terminal from a third terminal; setting a call session with each of the first and third terminals and registering a call pickup information of the third terminal in a call pickup table upon a determination that the first terminal is not in voice/video communication with the second terminal; setting a call session with the third terminal which made the call pickup request, canceling a call session with the second terminal in voice/video communication, and then registering the call pickup information of the third terminal in the call pickup table upon a determination that the first terminal is in voice/video communication with the second terminals; and transmitting received voice/video traffic to the third terminal which made the call pickup request via a second network based upon the call pickup information registered in the call pickup table upon receiving voice/video traffic from the first terminal via the first network, wherein said transmission of received voice/video traffic to said third terminal occurs regardless of the proximity of the first terminal to the third terminal and any terminal that is located closer to the first terminal in said first network.
