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.
<CR> Carriage return character, which value is specified with command S3.
<LF> 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
TE MS
USER & APPLICATIONS NETWORK
AT CMDs
Information text
Result codes
Network messages
HUAWEI UMTS M2M Module AT Command Interface Specification 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: <arg0>, <arg1>,
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 (<CR>) and linefeed character (<LF>) 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.
2 Interface Introduction

All rights reserved Page 16, Total 96
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.

4.2.2 Description
The SET command is used to set the format of the short message. The format has two
modes, and depends on the <mode> parameter. The two modes are: PDU mode and
text mode. The “text” mode is unable to display Chinese, so currently, only the PDU
mode is used. For the format of message in the PDU mode, see also “+CMGS
command”.
The READ command is used to return the current mode selection.
The TEST command returns the applicable <mode> values.

4.7.2 Description
The “SET” command is used to set the program of reporting new message to TE,
where,
<mode> and <bfr> are used to set the mode of reporting the new message notification
(including four types: +CMT, +CMTI, +CDSI, +CDS) to the TE.
<mt> is used to set whether reporting the new message to the TE, or storing the new
message in the MS and reporting the storage position when a new message is
received.
<bm> is not in use currently.
<ds> is used to set whether to report the message state report (+CDSI, +CDS).
The TEST command returns the supported parameter values.
Note: The set value of this command will be cleared to 0 after the MS is restarted. In
this case, no new message will be reported. The “AT+CNMI=0,0,0,0,0” mode is not
recommended.
4.7.3 Defined Values
<mode>: Set the message notification mode.
0 Buffer the message in the ME. If the buffer of ME is full, the new notification will
overwrite the old notification.
1 Send the message notification to the TE directly. When it is impossible to send
the notification (e.g. when in the online data mode), the notification will be discarded.
2 Report the message notification and message state report to the TE directly.
When it is impossible to send them (e.g. when in the online data mode), the message
notification will be buffered in the ME, and will be sent to the TE at a time later.
Note: The message notifications are buffered in the volatile storage. If the MS is
powered off before sending the message, the message will probably be lost. Therefore,
in case of <mode>=0 or 2, it is not allowed to use direct forwarding of message
(<mt>=2 and 3
<mt>: Set the rules of storing and notifying the received messages.
New messages can be stored and notified in the following three modes:
1 If SMS-DELIVER is not stored into MS, SMS-DELIVERs are routed directly to
TE.
+CMT: [<reserved>], <length><CR><LF><pdu>
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential

2 If SMS-DELIVER is stored into MS, indication of the memory location is routed to
the TE.
+CMTI: <mem>,<index>
3 If SMS-DELIVER is stored into MS, SMS-DELIVER indication is not routed to
TE.
In the above three modes, the interaction between TE and MS is shown in the
following diagram.
The relationship between the parameter value of <mt> and the mode of storing and
notifying various messages is shown in the following table.

1 Do not store message acknowledgement in MS, route message
acknowledgement directly to TE.
+CDS: <length><CR><LF><pdu>
2 If the message acknowledgement is stored in the MS, a storage position
notification will be sent to the TE via “+CDSI”.
+CDSI: <mem>,<index>
<bfr>: For use of setting buffer processing after transition from <mode>=0 to
<mode>=1, 2.
0 After entering the <mode>1-2, the buffered unsolicited result codes will be sent
to the TE at a time.
1 After entering the <mode>1-2, the buffered unsolicited result codes will be
emptied.
4.7.4 Informative Examples
For example, set CNMI=1,1,0,1,0.
It indicates that the new class1 messages will be stored in the MS first, and the
storage position will be reported (+CMTI: ME,1}; the message state reports will be
reported directly (+CDS: ).
When it is impossible to report the message notification (e.g. when in the online data
mode), the message notification will be discarded.

4.9.2 Description
EXECUTION command confirms reception of a new message which is routed directly
to the TE. This acknowledgement command shall be used when +CSMS parameter
<service> equals 1. For the usage of this command, see also description of “+CNMI”
command.
In PDU mode, it is possible to send either positive (RP-ACK) or negative (RP-ERROR)
acknowledgement to the network. Parameter <n> defines which one will be sent.
Optionally, an acknowledgement TPDU (SMS-DELIVER-REPORT for RP-ACK or
RP-ERROR) may be sent to the network. The entering of PDU is done similarly as
specified in command Send Message +CMGS, except that the format of <ackpdu> is
used instead of <pdu>. PDU shall not be bounded by double quotes.
MS shall not send another +CMT or +CDS result code to TE before previous one is
acknowledged.
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential
All rights reserved Page 37, Total 96
If ME does not get acknowledgement within required time (network timeout), ME
should send RP-ERROR to network, and should shall automatically disable routing to
TE by setting both <mt> and <ds> values of +CNMI to zero.
To make the MS report the message notification again, you need to set <mt> and <ds>
again.
If the command is executed but no message is available for confirmation, the “+CMS
ERROR” will be returned: <err>
The TEST command returns the supported <n> values. If only 0 is supported, it
indicates that the command does not support TPDU sending.
4.9.3 Defined Values

Type-of-Number(bit6…bit4). The values are as follows:
0 0 0 This value is written when the user does not know the authentication
information of the target address number. In this case, the address number is
organized at the network side.
0 0 1 This value is selected if the user knows that it is an international number,
or believes that it falls in the domestic range.
0 1 0 Domestic number. No prefix or suffix is allowed. This value is selected
when the user sends a message to a domestic telephone set.
0 1 1 A specific number in this network. It is used for management or service
and cannot be selected by the user.
1 0 1 The number type is the default 7bit code mode of GSM. It is not in use

If the number type is: ‘A1’, the corresponding <SCA> will be 05a131099200.
If the type is indicated as an international number ‘A1’, while the number 13902900
is a domestic number, it is necessary to additionally dial 86 before the number, hence
the corresponding <SCA> in this case is 06a16831099200.

8.3.2 Interface Description
The SET command is used to control “+CGREG” to report event proactively.
When <n>=1, and the state of network registration changes, the following will be
reported: +CGREG:< stat >
When <n>=2, and the cell information changes, the following will be reported:
+CGREG: <stat>[,<lac>,<ci>]
The READ command returns the current registration state <stat>. The position
information <lac> and <ci> is reported only when <n>=2.
8.3.3 Defined Values
<n>:
0 Disable proactive reporting of “CGREG”
1 Enable proactive reporting of “+CGREG <stat>”
2 Enable proactive reporting of “+CGREG: <stat>[,<lac>,<ci>]”..
<stat>:
0 Not registered. The MS is not searching the new operators to be registered.
1 Local network is registered
2 Not registered. But the MS is searching the new operators to be registered.
3 Registration rejected
4 Unknown reasons
5 Roaming network is registered
<lac>: Position code information, composed of four characters and expressed in
hexadecimal. (Example: “00C3”= “195” in decimal)
<ci>: Cell information, composed of four characters and expressed in hexadecimal.
Extended Information: according 3GPP Rel7, four characters are requested, but if
before Rel7, for example the currently network is Rel6 mostly, only the last two
characters is valid, the other characters is invalid and should be ignored. For example,
if the <CI> return 3B3DE1C, only DE1C is valid and could be used as DE1C is the last
two characters.

<Residual bit error ratio>: a string parameter that indicates the target value
for the undetected bit error ratio in the delivered SDUs. If no error detection is
requested, Residual bit error ratio indicates the bit error ratio in the delivered SDUs.
The value is specified as 'mEe'. As an example a target residual bit error ratio of 5•10-3
would be specified as '5E3' (e.g. +CGEQNEG:…,”5E3”,…)

+CGDATA=[<L2P> ,[<cid> [,<cid> [,…]]]] CONNECT
ERROR
+CGDATA=? +CGDATA: (list of supported <L2P>s)
9.2.2 Description
The execution command causes the MT to perform whatever actions are necessary to
establish communication between the TE and the network using one or more Packet
Domain PDP types. This may include performing a PS attach and one or more PDP
context activations. If the <L2P> parameter value is unacceptable to the MT, the MT
shall return an ERROR or +CME ERROR response. Otherwise, the MT issues the
intermediate result code CONNECT and enters V.25ter online data state.
Commands following +CGDATA command in the AT command line shall not be
processed by the MT.
The detailed behaviour after the online data state has been entered is dependent on
the PDP type. It is described briefly in 3GPP TS 27.060[34] and in more detail in 3GPP
TS 29.061[39] and the specifications for the relevant PDPs. PS attachment and PDP
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential
All rights reserved Page 75, Total 96
context activation procedures may take place prior to or during the PDP startup if they
have not already been performed using the +CGATT and +CGACT commands.
If context activation takes place during the PDP startup, one or more <cid>s may be
specified in order to provide the information needed for the context activation
request(s).
During each PDP startup procedure the MT may have access to some or all of the
following information -
The MT may have a priori knowledge, for example, it may implement only one PDP
type.
The command may have provided an <L2P> parameter value.
The TE may provide a PDP type and/or PDP address to the MT during in the PDP
startup procedure.
If any of this information is in conflict, the command will fail.
Any PDP type and/or PDP address present in the above information shall be
compared with the PDP type and/or PDP address in any context definitions specified
in the command in the order in which their <cid>s appear. For a context definition to
match -
The PDP type must match exactly.
The PDP addresses are considered to match if they are identical or if either or both
addresses are unspecified. For example, a PPP NCP request specifying PDP type =
IP and no PDP address would cause the MT to search through the specified context
definitions for one with PDP type = IP and any PDP address.
The context shall be activated using the matched value for PDP type and a static PDP
address if available, together with the other information found in the PDP context
definition. If a static PDP address is not available then a dynamic address is
requested.
If no <cid> is given or if there is no matching context definition, the MT shall attempt to
activate the context with whatever information is available to the MT. The other context
parameters shall be set to their default values.
If the activation is successful, data transfer may proceed.
After data transfer is complete, and the layer 2 protocol termination procedure has
completed successfully, the V.25ter command state is re-entered and the MT returns
the final result code OK.
In the event of an erroneous termination or a failure to start up, the V.25ter command
state is re-entered and the MT returns the final result code NO CARRIER or, if enabled,
+CME ERROR. Attach, activate and other errors may be reported.
The test command is used for requesting information on the supported layer 2
protocols.
This command may be used in both normal and modem compatibility modes.
9.2.3 Defined Values
<L2P>: a string parameter that indicates the layer 2 protocol to be used between the
TE and MT
PPP Point-to-point protocol for a PDP such as IP
M-xxxx manufacturer-specific protocol (xxxx is an alphanumeric string)
If the value is omitted, the layer 2 protocol is unspecified. Other values are reserved
and will result in an ERROR response.

9.4.2 Description
A group of setting environments indexed by <cid> are stored locally. Each stored
setting environment contains a group of parameters related to PDP. The SET
command stores a group of PDP-related parameters to the setting environment
indexed by <cid>. Initially, each setting environment is not defined. After a group of
parameters are stored via the SET command, the setting environment enters the
“defined” state. The number of defined setting environments that can be stored
depends on the value range of <cid>.
A special SET command “+CGDCONT= <cid>” will clear all parameters in the setting
environment indicated by <cid>.
The READ command returns all the parameter values of the defined setting
environments. The setting environments are displayed by means of linefeed.
The TEST command returns all supported values. In the response, they are displayed
one by one by using “PDP_type” values supported by MS as index. Each entry takes a
determined PDP_type value, and includes the supported value ranges of other
parameters under the value of PDP_type. The entries are displayed by means of
linefeed.
9.4.3 Defined Values
<cid>:
1-16: Index value of PDP setting environment. Other PDP-related commands can be
used for invoking the storage position through this index value.

10.7.2 Description
This command is used to close a TCP/UDP link or exit TCP/UDP function.
Link ID 1~5 means closing real link. TCP link needs to finish 4 times handshakes to
other side. UDP only needs to deactivate the local link.
Input 6 for closing listening function of server.
Input 7 for unsubscribing from network, the same as deactivating the network while
dialing.
If all parameters are default, means closing link 1, equally AT%IPCLOSE=1.
10.7.3 Defined Values
<link_id>: link ID
1～7 the range of link ID

Command Possible response(s)
%IPENTRANS <CR><LF>”>”
10.8.2 Description
This command is used to enable TCP/UDP transparent transfer mode. In this mode
the user data is transferred to remote terminal through TCP/UDP link without length
limit.
After “>” prompt, user can input sending data continuously, Ctrl-Z is used as a send
symbol, then wait for another.
At the same time of sending data ,the terminal data will appear after “<” prompt to tell
apart.
After “>” prompt, Ctrl-Q is used as a quit symbol, firstly send all the remained data,
then disable TCP/UDP transparent transfer mode.

16 Appendixes
16.1 Appendix 1 AT Command Description
16.1.1 Basic Commands
The format of a basic command is:
<command>[<number>]
Where, <command> is a single letter (A-Z) or a “&” plus a single letter, and <number>
is a decimal number composed of one or more digits. The 0s at the head of <number>
will be ignored. If a basic command that can carry <number> carries no <number>, the
<number> value is 0 by default. If a basic command that cannot carry <number>
carries a <number>, the information “TOO MANY PARAMETERS” will be returned.
16.1.2 S Register Command
All commands that begin with “S” are collectively called “S register command”.
Command format:
S<parameter number>?
S<parameter number>=<value>
The S register command name is composed of the letter “S” combined with a decimal
number. This decimal number is called “register sequence number (parameter
number)”. If the register is not identified, it indicates that this command does not exist,
and the “COMMAND NOT SUPPORT” information will be returned. Each S register
saves a character. If the command name is followed by “?”, it indicates a READ
recommend. The ASCII code values currently saved in this S register expressed by a
3-digit decimal number, will be returned. Make up three digits by filling 0s at the end if
there are less than 3 digits. If the command name is followed by “=”, the command is a
SET command. In this case, replace the characters stored in this S register with the
characters corresponding to the <value>.
16.1.3 Extended Commands and Manufacturer Defined Commands
The extended commands begin with “+”. The commands defined by the manufacturer
also begin with a special character, e.g. “$”, “%”. For purpose of this document, all
commands defined by manufacturers begin with “%”. All extended commands and
manufacturer-defined commands are divided into two categories: Action command
and parameter command.
I. Action commands
Action commands are the commands that carry out a specific action rather than only
dealing with local parameters of the MS, e.g. AT+CCFC, AT+CMGS. An action
command may carry parameters or not. Action commands include EXECUTION and
TEST.
1) EXECUTION command
Command format:
No parameter <name>
With 1 parameter <name>[=<value>]
With more parameters <name>[=<compound_value>]
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential
All rights reserved Page 88, Total 96
<compound_value> indicates multiple parameters, separated by “,” in the middle. For
the parameters that have a default value, they can be omitted and substitute the
default value. If all the parameters are omitted, the “=” behind <name> should be
omitted too. If <name> is not identified, it indicates that this command does not exist,
and the information “COMMAND NOT SUPPORT” will be returned. If <name> is
identifiable, and the command contains uncalled-for parameters, or the number of
parameters goes beyond the defined range, the information “TOO MANY
PARAMETERS” will be returned.
2) TEST command
Command format:
<name>=?
If the MS cannot identify <name>, the information “COMMAND NOT SUPPORT” will
be given. If the MS can identify <name>, and the command carries no parameter, the
information “OK” will be returned. If the command carries parameters, the value range
of each parameter will be returned first, then “OK” will be returned.
II. Parameter commands
Parameter commands refer to the commands that can only deal with the local
parameters of MS. These parameters may affect the execution of the action
commands. Parameter commands include SET, READ and TEST commands.
1) SET command
Command format:
With 1 parameter: <name>[=<value>]
With more parameters <name>[=<compound_value>]
The SET command is used to set the parameters. <compound_value> means multiple
parameters, separated by “,” in the middle. For the parameters that have a default
value, they can be omitted and substitute the default value. If all the parameters are
omitted, the “=” behind <name> should be omitted too. If <name> is not identified, it
indicates that this command does not exist, and the “COMMAND NOT SUPPORT”
information will be returned. If <name> is identifiable, and the command contains
uncalled-for parameters, or the number of parameters goes beyond the defined range,
the information “TOO MANY PARAMETERS” will be returned.
2) READ command
Command format:
<name>?
The READ command is used to read the current value of the parameter.
3) TEST command
Command format:
<name>=?
If the MS cannot identify <name>, the information “COMMAND NOT SUPPORT” will
be given. If the MS can identify <name>, and the command carries no parameter, the
information “ok” will be returned. If the command carries parameters, the value range
of each parameter will be returned first, then “OK” will be returned.
16.1.4 Abort Attribute:
Abort means the TE sends an instruction to interrupt a command being executed. The
“Abort” command must be issued before the command finishes execution, so it makes
sense only to the commands that require a certain time period for executing. However,
not all commands that require a certain time period for executing can be aborted,
HUAWEI UMTS M2M Module AT Command Interface Specification Confidential
All rights reserved Page 89, Total 96
depending on the abort attribute of the command. Each AT command has the abort
attribute. This attribute is a two-option choice. Namely, the command either supports
abort or does not support abort. The commands that support abort include some
basic commands and the EXECUTION command of action command. These
commands do not accept any abort request within 125ms after being issued. After the
command has been issued for 125ms but has not finish execution, if any character is
received from the TE, it will interrupt the execution of the command immediately.
The commands that support abort are as follows:
atD Can be aborted
atA Can be aborted
at+CLCK Can be aborted
at+COPS Can be aborted except “at+COPS=?”
at+CLCC Can be aborted
at+CLIP Can be aborted
16.2 Appendix 2 CME Error List
Note: The following table lists the possible CME errors and reasons for all the interface
command. The code in the first row of the table represents the <err> value of CME
ERROR. The numerals in the table represent the sequence number of reasons. The
table of correspondence between CME ERROR and text string is attached later,
together with detailed description on the reasons.
For example: “7” is filled in the column whose <err> is 16 in the “+CPWD=” command.
This indicates the “+CPWD=” may incur the CME ERROR whose <err> is 16. Its text
string is “incorrect password”. The reason is that the sequence number is 7, and the
detailed reason is “password incorrect”.
