摘要 |
A server apparatus recognizes start of a voice call including the first terminal based on an operation signal received from the first terminal. The server apparatus allows a packet storing voice data to go through to the first terminal when the packet is received from a second terminal connected via the network in a case where start of the voice call is recognized. The server apparatus estimates a bandwidth of the network based on a first response packet sent from the first terminal in response to a packet sent to the first terminal, calculates a bit rate of the voice call according to the estimated bandwidth, and notifies the first terminal of the calculated bit rate. The first terminal switches a bit rate of the voice call according to the notified bit rate. The delay in voice calls using a thin-client terminal can be shortened and achieves a high-quality voice call that addresses changes in the network bandwidth. |
