Teleconference management server device, teleconference management method and non-transitory computer-readable medium

A teleconference management method via a network comprising the steps of:

• receiving, from a first terminal device participating in a teleconference, first identification information identifying the first terminal device, and status information indicating a participation status in the teleconference of the first terminal device;
• transmitting a first request including the first identification information and the status information to a second terminal device, the second terminal device being a terminal device that is set in advance and that is not participating in the teleconference;
• receiving, from the second terminal device, a first response in response to the first request;
• setting, in response to receiving the first response, the second terminal device as a registered second terminal device whose participation in the teleconference is registered;
• receiving conference data in response to setting the registered second terminal device;
• identifying a transmission destination of the conference data, based on information included in the received conference data, such that when the first identification information is included in the conference data, the second terminal device is identified as the transmission destination, when second identification information identifying the second terminal device is included in the conference data, the first terminal device is identified as the transmission destination, and when third identification information identifying a third terminal device participating in the teleconference is included in the conference data, at least a part of a plurality of terminal devices including the first terminal device and the third terminal device and not including the second terminal device is identified as the transmission destination, the third terminal device being different from the first terminal device and the second terminal device;
• and
• transmitting the conference data to the identified transmission destination.

A teleconference management server device configured to manage a teleconference via a network, the teleconference management server device comprising:

• a processor configured to control the teleconference management server device to perform the steps of:
• receiving, from a first terminal device participating in the teleconference, first identification information identifying the first terminal device, and status information indicating a participation status in the teleconference of the first terminal device;
• transmitting a first request including the first identification information and the status information to a second terminal device, the second terminal device being a terminal device that is set in advance and that is not participating in the teleconference;
• receiving, from the second terminal device, a first response in response to the first request;
• setting, in response to receiving the first response, the second terminal device as a registered second terminal device whose participation in the teleconference is registered;
• and
• starting first transmission/reception processing in response to setting the registered second terminal, the first transmission/reception processing transmitting first conference data received from the first terminal device to the registered second terminal device, transmitting second conference data received from the registered second terminal device to the first terminal device, and not transmitting third conference data received from a third terminal device participating in the teleconference to the registered second terminal device, the third terminal device being different from the first terminal device and the second terminal device.
