Terminal device and packet processing method
View Patent ↗A packet processing method, the method includes, receiving TCP packets from a wireless access point. An A-MSDU packet is created by aggregating TCP ACK frames generated by the received TCP packets. When the current data transmission speed is less than or equal to a first threshold value and timeout for the A-MSDU packet sent to the wireless access point continuously occurs over a first predefined time, a transmission time interval is reduced by the first preset value and the packet size value is re-calculated according to the adjusted transmission time interval. When the current data transmission speed is greater than or equal to the second threshold value and the size of the created A-MSDU packet that achieves the packet size value occurs over a second predefined time, the packet size value is increased by the second preset value.
