Patent ID: 6917792

Claim:
A method for controlling the operation of a mobile communication terminal adapted to provide a high-speed data rate service, said mobile communication terminal including a first antenna mounted to a terminal body, a second antenna detachably mounted to said terminal body, a first radio frequency module connected to said first antenna and having a radio frequency transmitter and a radio frequency receiver, and a second radio frequency module connected to said second antenna and having a dedicated radio frequency receiver, said method comprising the steps of: sending a first query message to a user of said mobile communication terminal to confirm whether the connection of said second antenna has been made for the high-speed data rate service if said second antenna is connected to said second radio frequency module; sending a second query message to said external terminal to confirm whether the connection of said external terminal has been made for the high-speed data rate service if an external terminal is connected to said mobile communication terminal under and said second antenna is connected to said second radio frequency module; supplying battery power to both said first and second radio frequency modules and performing signal processes associated with said first and second radio frequency modules, if there is a response from at least one of said external terminal and mobile communication terminal user to said first and second query messages; determining whether a current mode of said mobile communication terminal is a traffic mode for the high-speed data rate service if there is no response to said first and second query messages; supplying said battery power to both said first and second radio frequency modules and performing said signal processes associated with said first and second radio frequency modules if the current mode of said mobile communication terminal is said traffic mode for the high-speed data rate service; and blocking the supply of said battery power to said second radio frequency module and performing said signal process associated with said first radio frequency module, if the current mode of said mobile communication terminal is not said traffic mode for the high-speed data rate service.
