Problems solved by technology

However, in Windows 7, the next-generation operating system developed by Microsoft, Microsoft has customized a set of Network Driver Interface Specification (NDIS) commands to realize the interaction between communication terminals and PCs, but the existing communication terminals are all If you use AT commands, if you want to replace the AT command structure with the NDIS command structure, you need to redesign the software, the upgrade cost is relatively high, and it may be limited by the software platform of the terminal product, which is not conducive to subsequent expansion.

Embodiment Construction

[0033] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. As known to those skilled in the art, each NDIS command is sent in the form of a data packet, which is referred to as an NDIS command packet hereinafter, and each NDIS command corresponds to one NDIS command packet.

[0034] Such as Figure 1A As shown, in one embodiment of the present invention, the PC side performs the following method:

[0035] S10, loading the AT command into the NDIS command package;

[0036] S15. Send the NDIS command packet to the communication terminal;

[0037] Correspondingly, such as Figure 1B As shown, the communication terminal side executes the following method:

[0038] S20, receiving and parsing the NDIS command packet loaded with the AT command;

[0039] S25. Extract the AT command.

[0040] The above embodiment of the present invention loads the AT command in the NDIS command, so that the terminal developer can use...

Abstract

The invention provides a method for processing an AT command through a network driver interface specification (NDIS), which comprises the following steps: loading the AT command in an NDIS command package by a computer; sending the NDIS command package to a communication terminal; receiving and analyzing an NDIS command return package of the NDIS command by the communication terminal; and extracting a processing result of the AT command from the return package. The method ensures that a developer can still easily and quickly develop a product based on a stable and mature AT command interaction by utilizing a current AT scheme under the condition that the AT command cannot be directly transmitted, thereby reducing the cost of upgrading. The invention also provides the computer, the communication and a system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a terminal for processing AT commands through a network driver interface specification (Network Driver Interface Specification, NDIS). Background technique [0002] The AT command is a command language developed by Hayes for communication devices such as mobile phones and modems. It is named because each command starts with "AT". Now, AT commands have become the de facto standard adopted by major communication terminal manufacturers. In the prior art, a personal computer (Personal Computer, PC) running a Windows operating system can send an AT command to a communication terminal through a port (such as USB, Bluetooth, etc.) certified by Microsoft Corporation, so as to realize communication terminals such as mobile phones, data cards, and modems. Interaction with PC. However, in Windows 7, the next-generation operating system developed by Microsoft, Microsoft...
