A mobile communication device includes: a first communication module configured to perform first wireless communication with a base station; a second communication module configured to perform second wireless communication with a hands-free device through a near field communication network; a power controller configured to supply power to the second communication module when an incoming signal is received from the base station; and a link controller configured to control the second communication module to establish a wireless link with the hands-free device after the power is supplied to the second communication module by the power controller, wherein the power controller maintains supplying the power to the second communication module when the wireless link is established by the link controller and stops supplying the power to the second communication module when the wireless link is unestablished by the link controller.
