Abstract

Abstract A video conferencing system ( 100 ) includes a switch ( 125 ), a server ( 140 ), a telephone device ( 152 ), and a node ( 102 ) in a packet-switched network ( 135 ). The switch ( 125 ) establishes a circuit-switched connection between a calling party number and a called party number. The server ( 140 ) associates first and second network addresses in a packet-switched network ( 135 ) with each of the called party and calling party numbers. The telephone device ( 152 ) transmits audio data via the circuit-switched connection. The node ( 102 ) in the packet-switched network ( 135 ) transmits packetized video between the first and second network addresses responsive to establishment of the circuit-switched connection.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 116 words
A method of setting up a video conference, comprising: receiving a calling party number and a called party number used for establishing a connection in a circuit-switched network; associating, via a lookup table, a first network address in a packet-switched network with the calling party number; associating, via the lookup table, a second network address in the packet-switched network with the called party number; sending a first message containing the second network address to the first network address via the packet-switched network; and sending a second message containing the first network address to the second network address via the packet-switched network, wherein each of the first and second network addresses comprises an Internet Protocol (IP) address.
Claim 2
Independent Claim 116 words
A method of setting up a video conference, comprising: receiving a calling party number and a called party number used for establishing a connection in a circuit-switched network; associating, via a lookup table, a first network address in a packet-switched network with the calling party number; associating, via the lookup table, a second network address in the packet-switched network with the called party number; sending a first message containing the second network address to the first network address via the packet-switched network; and sending a second message containing the first network address to the second network address via the packet-switched network, wherein each of the first and second network addresses comprises an Internet Protocol (IP) address.
Claim 3
Dependent Claim 22 words
The method of claim 1 , further comprising: establishing a circuit-switched connection between the calling party number and the called party number.
Claim 4
Dependent Claim 15 words
The method of claim 2 , further comprising: sending audio data via the circuit-switched connection.
Claim 5
Dependent Claim 35 words
The method of claim 1 , further comprising: receiving the first message at a node associated with the first network address; and transmitting packetized video between the first network address and the second network address.
Claim 6
Dependent Claim 35 words
The method of claim 4 , further comprising: receiving the second message at a node associated with the second network address; and transmitting packetized video between the second network address and the first network address.
Claim 7
Dependent Claim 21 words
The method of claim 5 , further comprising: transmitting packetized audio between the second network address and the first network address.
Claim 8
Dependent Claim 21 words
The method of claim 5 , further comprising: transmitting packetized audio between the first network address and the second network address.
Claim 9
Dependent Claim 17 words
The method of claim 1 , wherein the first and second messages are sent via instant messaging.
Claim 10
Dependent Claim 126 words
A server, comprising: a memory configured to store instructions; and a processor configured to execute the instructions in the memory to: receive a calling party number and a called party number used for establishing a connection in a circuit-switched network, associate, via a lookup table, a first network address in a packet-switched network with the calling party number, associate, via the lookup table, a second network address in the packet-switched network with the called party number, send a first message containing the second network address to the first network address via the packet-switched network, and send a second message containing the first network address to the second network address via the packet-switched network, wherein the first and second network addresses each comprise Internet Protocol (IP) addresses.
Claim 11
Dependent Claim 126 words
A server, comprising: a memory configured to store instructions; and a processor configured to execute the instructions in the memory to: receive a calling party number and a called party number used for establishing a connection in a circuit-switched network, associate, via a lookup table, a first network address in a packet-switched network with the calling party number, associate, via the lookup table, a second network address in the packet-switched network with the called party number, send a first message containing the second network address to the first network address via the packet-switched network, and send a second message containing the first network address to the second network address via the packet-switched network, wherein the first and second network addresses each comprise Internet Protocol (IP) addresses.
Claim 12
Dependent Claim 17 words
The server of claim 9 , wherein the first and second messages are sent via instant messaging.
Claim 13
Dependent Claim 13 words
The server of claim 9 , wherein the packet-switched network comprises an Internet.
Claim 14
Dependent Claim 127 words
A computer-readable medium containing instructions for controlling at least one processor to perform a method of setting up a video conference, comprising: receiving a calling party number and a called party number used for establishing a connection in a circuit-switched network; associating, via a lookup table, a first network address in a packet-switched network with the calling party number; associating, via the lookup table, a second network address in the packet-switched network with the called party number; sending a first message containing the second network address to the first network address via the packet-switched network; and sending a second message containing the first network address to the second network address via the packet-switched network, wherein the first and second network addresses each comprise Internet Protocol (IP) addresses.
