<p>A device, a method and a system for processing AT (ATtention) commands are provided in the present invention. The device for processing AT commands includes an AT command transmission module and an AT command reception module. The AT command transmission module is used for receiving service information from terminal modules and calling an application function to send AT channel application information to the AT command reception module. The AT command reception module opens AT channels for transmitting AT commands and receiving AT command response information and closes the AT channels, the usage of which has been finished, between the AT command transmission module and AT command reception module according to the AT channel application information, and transmits AT commands to a data conversion module, and receives AT command response information from the data conversion module. The present invention enables concurrent opening of multiple AT channels for transmitting AT commands so as to support service concurrency of the terminal module, and meanwhile, closure of the AT channels, the usage of which has been finished, when the services have been finished, thus saving a large quantity of channel resources compared with the prior art.</p> |
