Integral communication device and control method thereof

摘要

An integral communication device and method for controlling the integral communication device are provided for expanding the communication capability of a mobile terminal. An integral communication device of the present invention includes a plurality of communication modules that operate with different communication standards, a connector having terminals for electrical connection to a mobile terminal, a switch for switching the terminals of the connector between the communication modules, and a device controller for controlling the switch to establish electric links to the communication modules individually.

主权项

1. An external integral communication device, the device comprising:
a plurality of communication modules that operate with different communication standards; a connector comprising electric connection terminals for providing electrical connection between the external integral communication device and a mobile terminal; a switch for selectively activating electrical connections between the communication modules and the electric connection terminals of the connector; and a device controller configured to control the switch to establish electric links from the electric connection terminals to at least one of the communication modules, to exchange signals with the mobile terminal through at least one signal terminal and supply a power received from the mobile terminal through a power terminal to the at least one of the communication modules, wherein the terminals for electrical connection comprise:
at least one signal terminal for establishing a signal link with the mobile terminal;the power terminal for supplying the received power to the switch, the device controller, and the at least one of the communication modules selectively when the electric links are established to the at least one of the communication modules; anda ground terminal for grounding the integral communication device.
