Abstract

PURPOSE:To efficiently transmit/receive packets by connecting the conference attendants contained in plural packet switching device to one packet conference processing unit. CONSTITUTION:When transmission data packets 31, 32, and 33 are simultaneously transmitted from subscribers 1, 2, and 3, the packet 31 is transmitted to the packet conference processing unit 7 through packet switching devices 4 and 6. The packets 32 and 33 are also transmitted to the unit 7 similarly. In the unit 7, the packets 31 and 32 are OR-processed and made into one incoming packet 43. The resulting packet 43 is transmitted to the subscriber 3 via the device 6. Likewise, OR-processed packets 42 and 41 are transmitted to the subscribers 2 and 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packet conference switching system for holding a conference between three or more parties in a packet switching network.

[Prior Art] Conventionally, communication in a packet switching network has been one-to-one bidirectional communication.

[Problems to be solved] The conventional packet communication described above is one-to-one bidirectional communication, so when three or more parties participate in a conference, conference participants set up multiple calls among themselves. However, conference participants have to send the same data packets to each other, which has the disadvantage of inefficiency.

[Means for Solving Problems] This invention has been made in view of the above circumstances, and the packet conference switching system of the present invention connects a plurality of packet switches using relay lines to form a packet switching network, and In a packet conference switching system in which a conference is held between three or more subscribers accommodated in a packet switch, a packet conference processing device that performs packet conference processing is accommodated as a packet terminal, and conference participants are connected to the packet conference processing device. The feature is that a packet conference can be performed by connecting.

[Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram of a packet switching network showing an embodiment of the packet conference switching system of the present invention. In the figure, a packet switching network is formed by packet switching equipment 4.5.6, and the packet switching equipment 4.5.6 can communicate with each other. Subscribers l, 2 and 3 are placed in these packet switches a4.5 and a4.6, respectively. Further, a packet conference switching device 7 is connected to the packet switching device 4!16. This packet conference switching device 7 serves the above-mentioned subscribers 1.2.
A packet output from one of the three is sent to the other two. In this case, if there are two packets to be sent to a specific party, these packets can be 'OR'ed.
"processed" and sent out as one packet.

The operation of the packet switching network diagram having the above configuration will be explained using FIG. 2.

Simultaneously outgoing data packets 3 from each subscriber l, 2.3
If 1.32.33 is output, the outgoing data bucket)
31 is supplied to the packet conference exchange apparatus 7 via the packet exchanges 4 and 6, and the outgoing data packet 32 is supplied to the packet conference exchange apparatus 7 via the packet exchanges Ja5 and 6. The outgoing data packet 33 is also supplied to the packet conference switching device 7 via the packet switching Ja6.

In the packet conference switching device 7, the outgoing data bucket) 31
and 32 are "OR'ed" into one incoming packet 43, which is sent to subscriber 3 via packet switch a6. Also, the outgoing data packets 31 and 33 are subjected to ""OR processing".
The incoming packet 42 is combined into one incoming packet 42 and sent to the subscriber 2 via the packet switches 6 and 5. Also, one outgoing data bucket 32 and 33 are "OR'ed" into one incoming packet, ) 41, which is sent to subscriber l via packet switches a6 and 4.

[Effects of the Invention] As explained above, the present invention connects a plurality of packet switching devices via relay lines to form a packet switching network, and allows conferences to be held between three or more subscribers accommodated in these packet switching devices. In the packet conference switching system to be implemented, a packet conference processing device is provided which is connected to one of the plurality of packet switches and sends the packets output from the - subscriber to other subscribers. When holding a conference using this technology, packets can be sent and received extremely efficiently.
