1 Scope
This document describes the AT interface of Huawei UMTS Module. The description
on the AT interface is only limited to the interface packet itself, the usage and use
procedure of TE and MS, and does not cover the contents which are not directly
related to the interface.
Note: Reinforced insulation or double insulation must be provided to isolate DC source
from AC mains supply.
1.1 Interface Overview
HUAWEI UMTS Module is a wireless terminal of UART or USB interface. It is used to
provide data service, voice and SMS functions.
This document describes the AT interface. Therewith no description or definition
explain for the document interface, and no temporary support to all kinds of parameter
values, so no suggestion of usage.
In the subsequent AT command parameters, two formats are involved: <>, and [], as
described below:
<...>
Parameters enclosed in angle brackets must be completed. Brackets
themselves do not appear in the command line.
[...]
Optional subparameter of a command is enclosed in square brackets.
Brackets themselves do not appear in the command line or response.
Carriage return character, which value is specified with command S3.
Linefeed character, which value is specified with command S4.

1.2 Interface Design Principles
1) Each interface should be functionally convergent.
2) Since the AT command is a packet transmitted via communication port, the packet
size is limited. For the transmission of AT command, in addition to the two characters
“AT”, a maximum of 1600 characters can be received (including the empty characters

Confidential
at the end). For the “response” message or URC reported by the board, the maximum
length is limited to 1600 characters.
3) Each command line can include only one AT command. For the URC instruction or
response reported from MS to TE, only one AT command is allowed in a command
line.
4) In order to make the commands and response formats more readable and
standard, except the original interfaces of Qualcomm, in all newly added interfaces,
e.g. no space can be contained in the commands such as AT%XXX: , ,
or behind %, colon or comma. No redundant space is allowed at the head or end.
5) After delivering each AT command, the TE cannot deliver the second AT
command until the MS has made response to this AT command. Otherwise, the
second AT command will not be executed.
6) 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 MS responds to the TE only after a long time of waiting,
e.g. the “AT+CCFC=?” command receives a response only after a long time after the
command is delivered, the MS may have received the reported instruction of RING on
this occasion. Namely, the reporting of RING may interrupt other responses, and other
URCs will not interrupt the response of command, and the interrupted part of the
response will continue being reported.
7) Unless otherwise specified, all default codes between TE and MS take on this
format: GSM 7 bit Default Alphabet. See also Section 6 in protocol 23.038. The
character @ is transmitted on the interface still according to 0x00 of 7bit coding. The
board software and API should be able to process this character. The board uploads
the carriage return character () and linefeed character () in the string in the
form of space.
8) a sort of compounding between quotation and comma can not exist in the string in
this current version. For the data format of UCS2 code, the code value should be
reported in the string format (if the code value is 0x553a, 553a should be reported).
9) The “Possible response” sent from MS to TE is composed of “Information text”
and “Result code”, where “Information text” is optional, and “Result code” is mandatory.
The format of “Possible response” is controlled by the ATV command, as detailed in
the ATV command description. All “Possible responses” listed in the tables in this
documents are in the ATV1 format.
1.3 Interface Change Principles
For the extended interface, parameters can be added behind the AT command. If the
interface fails to meet the new requirements as detected in the later stage of product
development, new parameters can be added on the basis of the original interface. In
addition, for all the currently available interfaces, if the command received by MS is not
identifiable, the “result code” of COMMAND NOT SUPPORT will be reported; if there
is one surplus command parameter, the MS will report the “result code” of the
corresponding TOO MANY PARAMETERS. No equal mark itself is deemed a surplus
command parameter.
All newly added AT command interfaces of the E630 project team begin with “%”. This
project team specifies that: In the AT command name such as “AT%XXX”, the number
of X cannot be more than 9 currently.

All interfaces herein refer to the interfaces between TE and MS, and are used for
guiding the implementation of the function requirements. The interface covers voice
call, short message receiving and sending, data traffic flow, phone book statistics,
supplementary service, and MS network system information setting.
For the commands sent from TE to MS, see also the detailed description in Appendix
16.1. Note that in the returned results of the TEST command, “,” and “-” are different.
For example, the returned result of “+CMGD=?” is: +CMGD: (1,5),(0-4), which means
that the first parameter value may be 1 or 5, and the second parameter value may
range from 0 to 4.

3.1.2 Description
This command is used to set whether to use result code: +CME ERROR:
indicates the error related to MS. When you set to use result code, the MS-related
error will generate a result code: +CME ERROR: , which will replace the ordinary
ERROR result code. If the error reasons are not related to MS, the ordinary ERROR
will still be returned.
3.1.3 Defined Values
:
Do not use +CME ERROR :result code, only ERROR is returned in case of
error occurrence.
Use +CME ERROR :result code, adopts the error code value.
Use +CME ERROR :result code, adopts the detailed string value of
the error.

3.3.1 Command Syntax
Command
Possible response(s)
S3=

3.3.2 Description
This command is used to set the command line carriage return character S3. S3 saves
the command line carriage return character in the form of ASCII code value. This
character is sent by TE. It means the end of a command line, and is identified by the
MS. This character is also sent by MS, and serves as a part of the header, tail and end
mark of the “result code” and “information response”.
When using the “S3=” command to set S3, the current S3 character can serve
as carriage return character of this command line, and the “result code” of this
command line will use the newly set S3 character immediately, rather than waiting until
the next command line.

“information response”.
If the S4 character is changed in a command line, the “result code” of this command
line will use the new S4 character immediately, rather than waiting until the next
