Problems solved by technology

For those who are not very familiar with AT commands, it is also difficult to use AT commands to obtain the information they want to know, because it is often necessary to rely on specific protocol documents

example 1

[0070] Example 1: Enter a Test type command from TE to TA:

[0071] TE->TA AT+CMDINFO=?

[0072] Then TA->TE returns all AT command information that meets the query conditions supported by TA

[0073]

[0074] The above ellipsis indicates other supported AT command information that has not been listed, and the following is the same.

example 2

[0075] Example 2: Input Set command from TE to TA:

[0076] TE->TA AT+CMDINFO="CP" means the AT command information starting with CP.

[0077] Then TA->TE returns all AT command information that meets the query conditions supported by TA

[0078]

example 3

[0079] Example 3: Input AT command from TE to TA:

[0080] TE->TA AT+CMDINFO=, "CUSTOM" means the supported private AT command information.

[0081] Then TA->TE returns all AT command information that meets the query conditions supported by TA

[0082]

[0083] You can also perform multiple queries as in Example 4 below,

Abstract

The invention discloses an AT command query method and system. Query the AT commands supported by the mobile device through the terminal adapter in the mobile device. The terminal adapter includes a processing unit and a storage unit. The processing unit is used to execute the AT command query program pre-written in it, and the storage unit is used to store the information in the mobile device. Supported AT command set, the final processing unit returns the AT command set that meets the requirements to the terminal device, and the AT command set supported by the mobile device used can be obtained conveniently and quickly.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an AT command query method. Background technique [0002] The AT (Attention) command set is sent from the terminal equipment (Terminal Equipment, TE) or data terminal equipment (Data Terminal Equipment, DTE) to the terminal adapter (Terminal Adapter, TA) or data circuit terminal equipment (Data Circuit Terminal Equipment, DCE) of. Through the TA, the TE sends AT commands to control the functions of the mobile terminal (Mobile Terminated, MT) and interact with GSM network services. Calls, text messages, phonebooks, data services, faxes, etc. can be controlled through AT commands. [0003] In the early 1990s, AT commands were only used for Modem operations. There is no precedent for controlling text messages on mobile phones, only a protocol called SMS Block Mode has been developed to fully control SMS through terminal equipment (TE) or computers. A few years later, the majo...
