Problems solved by technology

[0006] However, when the above-mentioned mobile communication terminal is connected to each external power supply, transistors must be provided in each power supply for recognition and identification, and the MSM should allocate each GPIO terminal according to each power supply, so it is not suitable for small-area mobile communication terminals. The interior embodies the current trend of multiple functions

Abstract

The present invention relates to an external power identifying method of mobile communication terminal, in particular an external power identifying method with a level transceiver and output terminal of GPI01.2 provided with the power testing section of the mobile communication terminal, which is characterized by comprising a first step of setting the DC level outputted from the GPI01.2 of the level transceiver provided with the power testing section of the mobile communication terminal. A second step of estimating external power connecting to input terminal of the level transceiver according to set DC level in first step; a third step of operating charge algorism at same time of executing start according to estimated external power in the second step. The function of the mobile terminal and the power section can be simplified.

Description

technical field [0001] The present invention relates to an additional function of a mobile communication terminal, and in particular to a method for identifying an external power supply of a mobile communication terminal, which includes a level transceiver in the power detection section of the mobile communication terminal, so that each transistor is used when connecting an external power supply. The MSM recognizes the external power source connected and simplifies the startup method. Background technique [0002] Recently, with the rapid development of communication technology, mobile communication systems that enable individuals to communicate with others while moving from one place to another at an arbitrary place have been developed and utilized. [0003] In addition, the mobile communication terminal used in the above mobile communication system is equipped with various additional service functions in addition to the conventional simple call function. [0004] The abov...
