Chinese: AT命令在蜂窝移动通信设备系统中的应用
English : Digital cellular telecommunications system AT command
This European Telecommunication Standard (ETS) specifies a profile of AT commands and recommends
that this profile be used for controlling Mobile Equipment (ME) functions and GSM network services from
a Terminal Equipment (TE) through Terminal Adaptor (TA). The command prefix +C is reserved for Digital
Cellular in ITU-T Recommendation V.25ter [14]. This ETS has also the syntax details used to construct
these extended GSM commands. Commands from ITU-T Recommendation V.25ter [14] and existing
digital cellular standards (TIA IS-99 [15] and TIA IS-135 [16]) are used whenever applicable. Some of the
new commands are defined such way that they can be easily applied to ME of networks other than GSM.
ITU-T T.31 [11] and T.32 [12] fax AT commands may be used for GSM fax transmission from TE. GSM
Short Message Service AT commands are defined in GSM 07.05 [24]. GPRS AT
