Information processing device, communication method, and communication system

An information processing device configured to communicate with a second information processing device associated with a first user via a network, the information processing device comprising:

• a processor;
• and
• a memory storing programmed instructions that, when executed by the processor, are operable for causing the information processing device to
• display a list of second users while a call is in progress with the second information processing device;
• receive a selection of one of the second users displayed on the list;
• and
• transmit a request for participation in the call with the second information processing device to a third information processing device, the third information processing device being associated with the selected one of the second users.

A communication system, comprising:

• an information processing device configured to communicate with a second information processing device associated with a first user via a network;
• and
• a communication management device configured to communicate with the information processing device,
• wherein the communication management device includes a processor and a memory storing programmed instructions that, when executed by the processor, are operable for causing the communication management device to
• store in a memory a user management DB, the user management DB including expertise and operating statuses of second users, and
• transmit the expertise and the operating statuses of the second users stored in the user management DB to a third information processing device, the third information processing device being associated with one of the second users,
• wherein the information processing device includes a processor and a memory storing programmed instructions that, when executed by the processor, are operable for causing the information processing device to
• receive the expertise and the operating statuses of the second users from the communication management device via the network,
• display a list of the second users while a call is in progress with the second information processing device,
• receive a selection of one of the second users displayed on the list, and
• transmit a request for participation in the call with the second information processing device to the third information processing device, the third information processing device being associated with the selected one of the second users.
