Abstract

The invention relates to a method for determining an outside device connected to a portable terminal and a determining device, in particular to a method for determining an outside device connected to a portable terminal and a determining device differentiating the outside device connected to a connecting part into a universal series bus device group and a standard sharing pin connecting device group by using a port contained in a control part, so as to differentiate the device belonging to the corresponding device group into, such as universal series bus device for communication, universal series bus device for charging and special charger, and the like.

Description

technical field [0001] The present invention relates to a method and device for discriminating external devices connected to a portable terminal, and more particularly to a method and device for discriminating types of external devices respectively connected to various interfaces of a portable terminal. Background technique [0002] Recently, portable terminals have been widely used in many fields due to their features such as portability, ability to store various programs, and high usability. Among them, the number of users and applicants of mobile communication terminals is rapidly increasing due to the feature that voice calls can be made while moving. [0003] In the early stage, the portable terminal was very heavy and large in order to stabilize the battery and other components, so it is not true to call it portable. But recently, with the development of components and the development of batteries, the weight and size of portable terminals have become very small, and ...
