通信装置、通信装置の通信方法及び通信装置の通信制御プログラム
Document Type and Number:
Japanese Patent JP5267416
Kind Code:
B2
Abstract:
A terminal 3B computes a correlation coefficient between jitter measured at a terminal 3A and jitter measured at the terminal 3B for the same time (S21). If the absolute value of the correlation coefficient is equal to or larger than a specified threshold value (YES at S22), there is a correlation between the jitter of the terminal 3A and jitter of the terminal 3B. Accordingly, congestion may occur at the same time in an uplink direction and a downlink direction in a network. Therefore, based on QoS information of the terminal 3B, a session control portion of the terminal 3B performs one of an encoding speed conversion within a codec, a transmission packet length conversion, a packet transmission interval conversion, a packet transmission priority conversion, and a type conversion between a first codec and a second codec (S23) to achieve efficient communication in response to the congestion in the network.
