Claim:
1. A method for controlling an uplink transmission of a terminal including a first central processing unit (CPU) buffer, a second CPU buffer and a network buffer which is related to a cellular interface and a wireless local area network (WLAN) interface, the method comprising: selecting, by the terminal, application traffic to be processed between Network Application (NA) traffic which is buffered in the first CPU buffer and Non-Network Application (NNA) traffic which is buffered in the second CPU buffer based on an amount of network traffic in the network buffer and an amount of a transmissible traffic of the terminal; controlling, by the terminal, a central processing unit (CPU) speed based on the application traffic and processing the application traffic at the CPU speed; maintaining, by the terminal, the processed application traffic as the network traffic in the network buffer; determining, by the terminal, a network interface between the cellular interface and the WLAN interface for the uplink transmission based on the CPU speed, an amount of the NA traffic in the first CPU buffer and the amount of the network traffic in the network buffer; controlling, by the terminal, a data rate and transmission power for the uplink transmission based on the CPU speed, the amount of the NA traffic in the first CPU buffer, and the amount of the network traffic in the network buffer; and transmitting, by the terminal, the network traffic based on the data transmission rate and the transmission power through the network interface.
