Transmission/reception channel matching apparatus and method for mobile communication terminal and mobile phone test equipment

A transmission/reception channel matching apparatus for a mobile communication terminal and a mobile phone test equipment, comprising:

• mobile communication terminal-side terminals connected to option pins of a serial communication port provided in the mobile communication terminal in a one-to-one correspondence;
• transmission and reception terminals corresponding to transmission and reception channels of the mobile phone test equipment for measuring call quality of the mobile communication terminal;
• a channel information database for storing information about option pins, set for additional serial communication channels, for identification information of the mobile communication terminal;
• a switching unit for selectively connecting the mobile communication terminal-side terminals to the transmission and reception terminals in compliance with a channel matching command;
• and
• a control unit for receiving the identification information of the mobile communication terminal, accessing the information about option pins, automatically setting transmission and reception channels of the mobile communication terminal and transmission and reception channels of the mobile phone test equipment based on the accessed information about option pins, and outputting the channel matching command to the switching unit.

A transmission/reception channel matching method for a mobile communication terminal and a mobile phone test equipment, comprising steps of:

• a) determining a state of connection between option pins of the mobile communication terminal having unique additional serial communication channels and mobile communication terminal-side terminals, and performing transmission channel matching based on results of the determination;
• b) outputting a transmission signal for reception channel matching to a transmission channel;
• c) detecting a reception signal corresponding to the transmission signal from the option pins, except for an option pin set for the transmission channel;
• and
• d) setting the reception channel based on results of the detection of the reception signal.
