A method, device and system for processing at commands

Abstract

The invention discloses an AT command processing method, device and system, which are used to realize parallel processing of AT commands, reduce the blocking time of AT commands, and improve the processing efficiency of AT commands. The method is: the application processor adds AT instructions whose expected processing time exceeds a set threshold into the first instruction queue of at least two instruction queues, and adds AT instructions whose expected processing time does not exceed the set threshold into at least two instruction queues. In the instruction queue with the smallest total expected processing time, according to the corresponding relationship between the instruction queue and the virtual port of the baseband processor, the AT instructions are obtained from each instruction queue and sent to the baseband processor for parallel processing through the virtual port corresponding to the instruction queue to which it belongs. ; The application processor obtains the processing result of the AT instruction returned by the baseband processor from the corresponding virtual port, and deletes the AT instruction that obtains the processing result from the instruction queue corresponding to the virtual port.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an AT command processing method, device and system. Background technique [0002] The AT (Attention) instruction set is sent from the terminal equipment (Terminal Equipment, TE) to the terminal adapter (Terminal Adapter, TA). According to the regulations in the 3GPP protocol, each AT command implements different functions according to different parameter configurations. [0003] The communication between the application processor (Application Processor, AP) and the baseband processor (Baseband Processor, BP) can be realized by using the AT command. Users can make phone calls, send text messages, dial-up Internet access and other functions through AT commands. [0004] Such as figure 1 Shown is the existing AT command processing process, the AP puts the new AT command into the tail of the queue, takes out the AT command to be processed from the queue head, and se...

AI Technical Summary

Problems solved by technology

[0005] The existing AT commands are processed in a serial manner. During the processing of AT commands by BP, AP cannot send the next AT command while waiting for BP to return the processing result, which will cause subsequent AT commands to be processed to be blocked.
