Abstract

The invention discloses a mobile communication terminal, comprising a five-pin USB connector, an application processing module, a CDMA wireless module, a bluetooth module, an audio coding and decoding module, a WIFI module and a first analog switch; wherein, the application processing module comprises a UART channel and a USB channel; the first analog switch is connected with the USB connector and the application processing module and is used for switching the UART channel and the USB channel; the application processing module is used for receiving and outputting debugging information from the CDMA wireless module via the UART channel under the condition that the first analog switch is switched to the UART channel, and for providing programs to the CDMA wireless module via the USB channel under the condition that the first analog switch is switched to the USB channel; the CDMA wireless module is used for sending the debugging information to the application processing module via the UART channel and for downloading the programs from the application processing module via the USB channel. The mobile communication terminal solves the problem of complex debugging information output and download program interface setting.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a mobile communication terminal. Background technique [0002] Wireless Local Area Network (WLAN for short) is based on the Internet Protocol (IP for short), which can provide a certain range of high-speed data connections, and can communicate with each other and realize resource sharing network system. The essential feature of WLAN is that it no longer uses communication cables to connect computers to the network, but connects them wirelessly, so that the construction of the network and the movement of terminals are more flexible. It adopts 2.4GHz or 5.8GHz industrial scientific medical radio frequency band communication (Industrial, Scientific, Medical, referred to as ISM) frequency for transmission, and the transmission distance can reach tens of meters, and it can reach hundreds of meters with special technology. WLAN has a series of standards such as 802.11a / b / g / n. [00...
