Method and system for parallel processing AT command

The invention discloses a method and a system for parallelly processing AT commands. The method comprises the following steps that: an AT command processor is provided with at least one port entity which is distributed with port number; the AT command processor receives the AT commands from a serial port and allocates the AT commands to port entities, the port entities mark MT control messages which are obtained by converting the AT commands corresponding to the port entities through the port number of the port entities, and the marked MT control messages are sent to a protocol stack of a mobile terminal; the protocol stack of the mobile terminal containing at least one functional module receives the marked MT control messages and transfers the MT control messages to corresponding functional modules for processing, and the processed MT control messages are sent back to the AT command processor; and the AT command processor acquires corresponding AT command result codes and the port number from the MT control
