Received data processing method in communication device for supporting bluetooth wireless communication

Abstract

A received data processing method in a wireless communication between devices that support a bluetooth wireless technology is provided. The method for processing data received through a wireless channel, in a communication device that supports bluetooth wireless communication, includes the steps of (a) a bluetooth module receiving data through a wireless channel, (b) the bluetooth module informing a bluetooth host that data received through a universal serial bus (USB) exists in the bluetooth module, and (c) the bluetooth host reading the data received by the bluetooth module in the step (a) through the USB when the bluetooth host is informed that received data exists in the step (b). According to the received data processing method, it is possible to prevent overhead from occurring due to unnecessary request for data by the bluetooth host generating request for data through the USB only when the received data exists in the bluetooth module. Accordingly, it is possible to minimize load of the bluetooth host and to improve data receipt bandwidth in a bluetooth host controller interface (HCI) universal serial bus (USB) transport layer. Also, the entire USB transmission speed is increased since request for data can be generated at the point of time at which data is received.
