Document Type and Number:
WIPO Patent Application WO/2016/084429
Kind Code:
A1
Abstract:
When a plurality of control devices for controlling sessions are provided in a communication system, there arises a problem in that an information transmission path becomes longer if information to be transmitted between communication terminals is transmitted via the plurality of control devices. A control device 50 transmits to a common management device 60 an IP address of a terminal 10 connected to said control device 50, while receiving an IP address of a terminal 10 connected to another control device 50, this IP address having been transmitted by the common management device 60. The control device 50, upon receiving a communication start request transmitted by the terminal 10 connected to said control device 50, transmits the request to the terminal 10 connected to the other control device, on the basis of the IP address.
