AT Command Interface Specification
Introduction
1.2 Overview
This document describes certain AT commands (implemented by terminal devices) of
international standards, such as 3GPP and ITU-T, according to the requirements of terminal
devices. In addition, this document describes the Huawei proprietary AT command interfaces
that are implemented by terminal devices. These Huawei proprietary AT command interfaces
help implement a certain function.
This document does not describe the interfaces that have been defined by standards or
implemented by the MT but are not required by the Huawei terminal product. The description
of AT command interfaces covers only the data packets of interfaces, the methods and
processes for the TE and the MT to use interfaces, excluding the contents that are not directly
related to interfaces. In addition, this document describes only the AT command interfaces
falling within the range of Rm interfaces between the TE and MT, excluding the AT command
interfaces falling within the range of Um interfaces between the MT and IWF.
AT commands are communication command protocols between TEs and MTs. If a new MT is
to interconnect with an existing TE implemented based on this AT specification, the MT must
comply with the specification. For example, to interconnect with the unified background of an
existing PC, a new module must comply with this specification. A PC application or tool must
comply with this specification to interconnect with existing terminal devices. If a TE or MT
does not communicate by using AT commands, this specification does not apply.
1.3 Document Conventions
Throughout the document, the module is referred to as ME, MS, TA or DCE. To control your
module you can simply send AT Commands via its serial interface. The controlling device at
the other end of the serial line is referred to as TE, DTE or plainly "the application" (probably
running on an embedded system).
Section "Property Description" of each command marks the property of each AT command.
Where, N means No, Y means Yes and NA means Not Applicable.
For example:
Saving upon Power-off
PIN
N
Y
The settings are described as follows:
Parameter settings in the command are not saved after the MT is powered off.
This command is controlled by PINs.
1.4 AT Command Syntax
1.4.1 AT Command Description
An AT command controls the rules for interaction between the TE such as PC and MT such as
MS. Figure 1-1 shows the interaction between the TE and MT.

Introduction
1.4.3 AT Command Parameter
You are not advised to use various parameter values that are not described in this document or
not supported currently as described in this document.
The AT command parameters described in the following chapters are in two formats: <> and
[], which are described as follows:
<...>:
The parameter inside these angle brackets is mandatory. The <> does not exist
in a command.
[...]:
The parameter inside these square brackets is optional. The [] does not exist in a
command or a response.
:
Carriage return character, which value is specified with command S3.
:
Line feed character, which value is specified with command S4.
According to the AT command specifications for GSM and WCDMA in 3GPP TS 27.007,
there is a component named TA between TE and MT. Physically, TA can be integrated with
either TE or MT. In this document, TA is integrated with MT. In TIA/EIA IS 707-A, TA is not
specified. To simplify the description in this document, TA is ignored. The client on a
computer is treated as TE, and MT is treated as TA+MT.
If all parameters are not specified, "=" is not required.
1.5 Abort Attributes of AT Commands
Some action commands that require time to execute may be aborted while in progress.
Aborting of commands is accomplished by the transmission from the DTE to the DCE of any
character. A single character shall be sufficient to abort the command in progress; however,
characters transmitted during the first 400 milliseconds after transmission of the termination
character shall be ignored (to allow for the DTE to append additional control characters such
as line feed after the command line termination character). To insure that the aborting
character is recognized by the DCE, it should be sent at the same rate as the preceding
command line; the DCE may ignore characters sent at other rates. When such an aborting
event is recognized by the DCE, it shall terminate the command in progress and return an
appropriate result code to the DTE, as specified for the particular command.
The following commands can be aborted.

1.6 Rules for Running AT Commands
1.
Each interface should be functionally convergent.
2.
Each command line contains only one AT command and ends with a carriage return
character. For the URC instruction or response reported from MT to TE, only one AT
command is allowed in a command line. In principle, users are not allowed to run S3/S4
format modification commands. This rule is applicable to the communication between
the MT and TE programs.
3.
For an AT command that cannot be interrupted, after sending the AT command, the TE
must wait until the MT responds to the AT command before sending the second AT
command.
4.
For the AT command to which the response is given only after a long time, in order to
prevent interference on other events, it is recommended to report the final execution
result asynchronously. If the ME responds to the TE only after a long time of waiting,
the response of command may be interrupted by URC. There are two kinds of
interruption:
−
Case 1: A URC is presented when the TE is waiting for response after sending a
command. This command will be kept in waiting state until the TE finishes
receiving the URC, and then the response to this command is presented.
−
Case 2: A URC is presented when the TE is waiting for response after sending a
command. The command continues to be executed. Therefore, response to the
command may be mixed with the URC.
5.
A string refers to a byte stream (excluding the quotation marks or commas) that is placed
inside double quotation marks. Special note should be specified if the byte stream need
not be enclosed in double quotation marks.
6.
The current version does not support escape character. The code value of a data format in
the UCS2 coding is reported as characters. For example, if the UCS2 code of a Chinese
character is 0x553a, the 553a is reported.

Introduction
7.
A possible response sent by the MT to the TE consists of Information text and Result
code, in which Information text is optional and Result code is mandatory. The format of
a possible response is controlled by the ATV command. For details, see the description
of the ATV Command. In this document, all possible responses listed in tables follow the
ATV1 format.
8.
The meaning of the command without any parameter should be described in the
document. And it is not recommended to use the command not setting any parameter.
9.
For the AT command that is controlled by PIN, if it is sent in PIN restricted mode, MT
will response with +CME ERROR: SIM PIN required.

The read command queries the current value.
For PS and CS incoming call:
When ATS0=0, the call will not be auto-answered. Otherwise, the call will be auto-answered
after ATS0 rings. The maximum number of rings is determined by the network configuration.
When PS call is incoming and ATS0 is set to more than the maximum number, the current PS
call will not be auto-answered.

2.12.2 Interface Description
The set command notifies TA of the TE's current character set so that TA can correctly convert
TE's and MT's character sets. If TA uses an 8-bit interface but TE uses a 7-bit character set,
the most significant bit of a character sent by the TE is set to 0.
2.12.3 Parameter Description
: at present, the default character set used by MS is "IRA". If AT+CSCS does not
contain any parameter, that means set the current character as the default character:
"GSM"
GSM 7 bit default alphabet (3GPP TS 23.038); this setting causes easily
software flow control (XON/XOFF) problems.
"IRA"
International reference alphabet (ITU-T T.50)
"UCS2"
16-bit universal multiple-octet coded character set (ISO/IEC10646);
UCS2 character strings are converted to hexadecimal numbers from 0000
to FFFF; e.g. "004100620063" equals three 16-bit characters with decimal
values 65, 98 and 99.
If MT is using GSM 7 bit default alphabet, its characters should be padded with 8th bit (zero) before
converting them to hexadecimal numbers (i.e. no SMS-style packing of 7-bit alphabet).
