Abstract:
1. A method of operating a communication system, the method comprising: in a first Time Division Multiplex (TDM) node, receiving first signaling for a communication session for a first user and transferring second signaling for the communication session to a packet system; in a second TDM node, receiving third signaling for the communication session from the packet system and transferring fourth signaling for the communication session for a second user; in the first TDM node, receiving first user communications for the communication session, and in response to the first signaling, transferring the first user communications to the packet system; in the second TDM node, receiving the first user communications from the packet system, and in response to the third signaling, transferring the first user communications for the second user; in the first TDM node, receiving fifth signaling for the communication session, and in response, transferring sixth signaling for the communication session to the second TDM node, receiving second user communications for the communication session, and transferring the second user communications to the second TDM node with the packet system removed from the signal path between the first TDM node and the second TDM node; and in the second TDM node, receiving the second user communications from the first TDM node, and in response to the sixth signaling, transferring the second user communications for the second user; in the first TDM node, receiving seventh signaling for the communication session and transferring eighth signaling for the communication session to the packet system; in the second TDM node, receiving ninth signaling for the communication session from the packet system; in the first TDM node, receiving third user communications for the communication session, and in response to the seventh signaling, transferring the third user communications to the packet system; and in the second TDM node, receiving the third user communications from the packet system, and in response to the ninth signaling, transferring the third user communications for the second user.
