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

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.
<CR>:
Carriage return character, which value is specified with command S3.
<LF>:
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.

AT+CLCK

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.

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.

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
<chset>: 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).

4.1.2 Interface Description
This command queries the network state and registers network selection mode currently by
the MS.
The execution command selects the network automatically or manually.
The read command queries the current network selection mode. If the registration is
successful, the current operator information will be returned.
The test command returns the list of (up to 20) operators existent in the current network.
- When <mode>=1, the command is aborted, and it will return OK for aborting.
- When the LTE network is manually registered through AT+COPS command with the parameter
<AcT>, CSFB voice is unavailable.

4
Manual/automatic (<oper> field shall be present); if manual selection fails,
automatic mode (<mode>=0) is entered. (not supported currently)
<oper>: string type.
<format>: indicates if the format is alphanumeric or numeric; long alphanumeric format can
be upto 16 characters long and short format up to 8 characters (refer GSM MoU SE.13).
Numeric format is the GSM Location Area Identification number (refer 3GPP TS 24.008
subclause 10.5.1.3) which consists of a three BCD digit country code coded as in ITU-T
E.212 Annex A, plus a two BCD digit network code, which is administration specific;
returned <oper> shall not be in BCD format, but in IRA characters converted from BCD.
Hence the number has structure: (country code digit 3)(country code digit 2)(country code
digit 1)(network code digit 3)(network code digit 2)(network code digit 1).

4.16 AT+CUSD-USSD Command
Users can run USSD commands using mobile devices to request specific services from the
network, and the network also can send USSD commands to devices to implement specific
services. Unlike SMS, USSD allows real-time bidirectional data exchange so that it can be
used in services, such as stock information query. Currently, many value-added services, such
as stock, lottery, weather forecast, and flight information query, are provided using USSD.

This command provides control on the supplementary service USSD. It supports the operation
originated from the network side or the terminal side.
<n> disables or enables proactive reporting of URC. This reporting may be response to the
terminal-originated service at the network side, or service request originated at the network
side:
+CUSD: <m>[,<str>,<dcs>]
If the <str> field is provided in the delivered command, the message sent to the network side
may be the USSD request originated at the terminal side, or the response to the network-side
request from the terminal. The response (USSD string) from the network will be included in
the subsequent +CUSD result code.
Besides, <n>=2 exits the current USSD session.
The test command returns all the supported n values.

<str>: a string type value that indicates USSD-string. Valid USSD characters are '0'-'9', '*' and
'#'.
- When USSD is transmitted in coding mode (non-transparent mode), the value of <str> is
set by running AT+CSCS. The MT will encode the value to the data that complies with
the requirement specified by <dcs> and send the data to network side.
- When USSD is transmitted in transparent mode using Huawei's proprietary scheme, the
value of <str> is not controlled by AT+CSCS and not encoded or decoded by the MT.
The MT can send USSD data that contains a maximum 160 bytes to the network side.
The transmission mode for USSD is set by running AT^USSDMODE.
<dcs>: an integer type value that indicates USSD coding. (see 3GPP TS 23.038 Cell
Broadcast Data Coding Scheme in integer format).
When USSD is transmitted in coding mode, the MT supports GSM 7-bit and GSM 8-bit, but

4.21.2 Interface Description
This command allows the TE to specify a minimum acceptable profile, which is checked by
the MT against the negotiated profile returned in the PDP context establishment and PDP
context modification procedures.
The set command specifies a profile for the context identified by the (local) context
identification parameter, <cid>. The specified profile will be stored in the MT and checked
against the negotiated profile only at activation or MS-initiated modification of the related
context. Since this is the same parameter that is used in 7.1 AT+CGDCONT-Define PDP
Context and AT+CGDSCONT (refer to 3GPP TS 27.007 subclause 10.1.2), the
AT+CGEQMIN command is effectively an extension to these commands. The QoS profile
consists of a number of parameters, each of which may be set to a separate value.
A special form of the set command, AT+CGEQMIN=<cid> causes the minimum acceptable
profile for context number <cid> to become undefined. In this case no check is made against
the negotiated profile.
The read command returns the current settings for each defined context.

5.1.2 Interface Description
This parameter determines how the state of circuit 109 relates to the detection of received line
signal from the distant end. Changing the parameter will take effect immediately in both the
command and online command states.
In AT&C1 mode of operation, circuit 109 is not turned off until all data previously received
from the remote DCE is delivered to the local DTE. However, such buffered data shall be
discarded and circuit 109 turned off if the DTE turns off circuit 108 (if AT&D1 or AT&D2 is
set).
- If the command is sent from the USB interface or 2-pin serial port, OK is returned.
However, the command is invalidated.
- If the command is sent from the UART port, the command is validated.

Upon an on-to-off transition of circuit 108/2, the DCE instructs the underlying
DCE to perform an orderly cleardown of the call. The disposition of any data in
the DCE pending transmission to the remote DCE is controlled by the +ETBM
parameter (see 6.5.6 in ITU-T V.250) if implemented; otherwise, this data is sent
before the call is cleared, unless the remote DCE clears the call first (in which
case pending data is discarded). The DCE disconnects from the line. Automatic

6.7.2 Interface Description
The execution command writes a phonebook entry in location number <index> in the
currently selected phonebook memory storage. If the execution command contains only the
<index> parameter, the phonebook entry at the location specified by <index> will be deleted.
If <index> is left out, but <number> is given, the entry is written to the first free location in
the phonebook.
- If an entry is written successfully and <index> is not provided, +CPBW:
<written_index> is returned, indicating the location of the entry. The <number> field
cannot be null and the <text> field can be null.
- If no location is free, +CME ERROR: memory full is returned. Phonebook entries can be
written only when the phonebook storage type <storage> of the selected phonebook
memory storage is "SM" or "ON". If the phonebook storage is of any other type, an error
message will be returned, indicating that the write operation is not allowed.
- If the UE is unable to display the full text or email, they are cut from the tail end.
The read command returns the latest value of <written_index> or returns –1 when the value of
<written_index> is invalid.
After running the AT+CPBS command to change the current phonebook storage, you need to set
<written_index> to an invalid value.
The test command returns:
- The location range supported by the current storage;
- The list of supported <type>s;
- The maximum lengths of the <number> (excluding '+') and <text> fields.
When writing a phonebook entry, ensure that the lengths of all fields do not exceed their
maximum lengths.

7.1.2 Interface Description
The MT locally saves a group of PDP contexts with <cid> as the index. Each record of the
saved setting environment contains a group of PDP-related parameters.
The set command saves the group of PDP-related parameters in the PDP contexts that use
<cid> as the index. Each PDP context is initially undefined. After the set command saves a
group of parameters in a PDP context, the PDP context is defined. The number of defined
PDP contexts that can be saved at the same time is determined by the value range of <cid>.
A special form of the set command, AT+CGDCONT=<cid> causes the values for context
number <cid> to become undefined.
Because the LTE module needs a default PDP context (profile 0) to register on the LTE network, the
default PDP context should not be removed. And the corresponding <cid> is 0, so you cannot execute
AT+CGDCONT=0.
The read command queries the current settings for each defined context displayed in a
separate line.
If all PDP contexts are undefined, the default parameters of PDP context are returned. In which, the
default value of <cid> is 1, and it will be saved when MT is powered off.
The test command returns all the values supported for each context. In the response, the
<PDP_type> value supported by the MT is taken as the index and displayed in a separate line.
Each context has a confirmed <PDP_type> value and includes the supported value ranges of
other parameters with the specified<PDP_type> value. Each context is displayed in a separate
line.
7.1.3 Parameter Description
<cid>:
0-11
Index of a PDP context. Other PDP-related commands can use this index to
use the defined PDP context.
12-20
Reserved for internal use, not configurable.
21-31
Reserved for the network side for initiation of PDP context activation, not
configurable.

1
Directly send SMS-DELIVER indications to the TE. When a SMS-DELIVER
indication cannot be sent (for example, when in online data mode), it will be
discarded.
2
Directly send SMS-DELIVER indications and message status reports to the TE.
When a SMS-DELIVER indication and message status report cannot be sent (for
example, when in online data mode), they are buffered in the ME and sent to the
TE when they can be sent.
SMS-DELIVER indications are buffered in the MT's volatile memory. If the MT is powered off before
the indications are sent, messages may be lost. Therefore, when <mode> is set to 0 or 2, messages are
not recommended to be directly sent to the TE (that is, <mt> is not supported to be set to 2 or 3).
<mt>: sets the rules for saving messages and sending SMS-DELIVER indications. There are
four modes for storing new messages and sending new message indications.
0
No SMS-DELIVER indications are routed to the TE. (default value)
1

- AT+CNMI=1,1,0,1,0
Class 1 messages are stored to the MT, and then storage locations are reported (+CMTI:
"SM",1). Message status reports are directly sent (+CDS:).
If SMS-DELIVER indications cannot be sent (for example, when in online data state),
they will be discarded.
- AT+CNMI=1,1,0,2,0
Class 1 messages are stored to the MS, and then storage locations are reported (+CMTI:
"SM",1). Message status reports are stored to the MS, and then storage locations are
reported (+CDSI: "SM",2).
If SMS-DELIVER indications cannot be sent (for example, when in online data state),
they will be discarded.(The SMS messages and SMS-DELIVER indications are stored in
the MS and can be read using the AT+CMGL command; however, the TE cannot receive
the indications.)
- Other commonly-used settings include:
AT+CNMI=1,1,0,0,0: store the messages, and then send the storage locations to the TE;
do not send the message status reports.
AT+CNMI=1,2,0,0,0: do not store the messages but directly send them to the TE; do not
send the message status reports.

8.4.2 Interface Description
The execution command acknowledges the reception of a new message that is routed directly
to the TE. This acknowledgement command shall be used when AT+CSMS parameter
<service> equals 1. For the use of this command, see 8.3 AT+CNMI-New Message
Indications to TE.
- Set AT+CSMS=1 before AT+CNMI is set.
- The unsolicited report CDS is not supported to be confirmed by the command AT+CNMA currently.
In PDU mode, either positive (RP-ACK) or negative (RP-ERROR) acknowledgement can be
sent to the network. The parameter <n> defines which acknowledgement to be send.
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 9.14 AT+CMGS-Send Message (PDU Mode), except that the format of <ackpdu> is used
instead of <pdu>. PDU shall not be bounded by double quotation marks.
Before the previous message is acknowledged, the MT will not send another +CMT result
code to the TE.
If the MT does not receive acknowledgement within required time (network timeout), the MT
will send RP-ERROR to the network and automatically set both <mt> and <ds> values of
AT+CNMI to zero to prevent SMS-DELIVER indications and message status reports from
being sent to the TE. To enable the MT to send SMS-DELIVER indications and message
status reports to the TE, <mt> and <ds> must be reset.
If the command is executed when no acknowledgement is expected, +CMS ERROR: <err> is
returned.
The test command returns a list of supported <n> values. If the value supported is 0 only,
sending of TPDU is not supported.

<TP-UD>: indicates the user data field may contain a user data header. If the header is
contained (that is, the value of bit 6 in byte 0 is 1), the value of TP-UDL equals to the length
of the User-Data-Header plus the length of the User-Data. The value of <TP-UDL> depends
on the encoding scheme:
- If the default encoding scheme (7-bit encoding) is used, <TP-UDL> indicates the
number of septets contained in the user data.
- If the 8-bit encoding scheme is used, <TP-UDL> indicates the number of octets
contained in the user data.
- If the UCS2 encoding scheme is used, <TP-UDL> also indicates the number of octets
contained in the user data.
- If 7-bit, 8-bit or UCS2 compression encoding is used, <TP-UDL> indicates the number
of octets contained in the compressed user data.

9.14.2 Interface Description
The execution command sends a message to the network in the following procedure:
First, the TE sends AT+CMGS=<length><CR> to the MT.
After the MT responds to the TE with <CR><LF><greater_than><space>(IRA 13, 10, 62, 32),
the TE sends the PDU packets ending with <ctrl-Z>(IRA26).
9.14.3 Parameter Description
<length>: indicates number of actually sent TPDU characters/2 in decimal format ranging
from 0 to 9, and maximum length is 178.
<mr>: indicates message ID; a decimal number ranging from 0 to 255.
<ackpdu>: when <value> of AT+CSMS is 1 and supported by the network, this field will be
returned. Except that there is no <SCA>, the format of <ackpdu> is the same as that of the
PDU. This field is not supported currently.
<ctrl-Z>: indicates the end of a PDU. The characters are "0x1A".
<ESC>: cancels the sending of the message. The characters are "0x1B".
The format of a PDU is as follows: (The characters allowed in a PDU are '0'-'9', 'A'-'F', and
'a'-'f'. Two characters forms one octet. For example, '23'=0x23, '2a'=0x2a, all are
hexadecimal.)

For example: If <SCA> is 13902900, then <number> is 31099200.
If the length of <SCA> is an odd value, for example, 139029001, then <numbers> is
31099200F1.
If the number type is 'A1', then <SCA> is 05a131099200.
If the number type indicates that it is an international number 'A1', but the number 13902900
is a national number in China, it is necessary to add 86 before the number. In this case,
<SCA> is 06a16831099200.

11.12.2 Interface Description
This command unlocks a SIM locked MT and queries MT's SIM lock state. If the SIM locked
MT is customized by the operator, MT can only use the SIM card specified by this operator
(in the following description, a valid SIM card is a SIM card specified by the operator; an
invalid SIM card indicates a SIM card not specified by the operator). When an invalid SIM
card is installed on the MT, <unlock_code> is requested for unlocking the SIM lock. If the
unlock code is not entered, SIM-related services, including network registration, calling, and
messaging, are unavailable, but emergency calls are available.
The set command unlocks the MT's SIM lock.
- If the correct unlock code is entered, the MT's SIM lock will be removed permanently.
The MT can work with any SIM card and the unlock code will never be requested. After
the MT's SIM lock is removed permanently or the MT's SIM lock is disabled, if a unlock
code is entered, +CME ERROR: 3 will be returned.
- If the number of consecutive incorrect unlock code entry attempts exceeds 10 (the
number of consecutive incorrect unlock code entry can be specified. Generally, it is 10),
the MT's SIM lock will be locked permanently. The MT can only work with valid SIM
card. After the MT's SIM lock is locked permanently, if a unlock code is entered again,
+CME ERROR: 3 will be returned.
The read command queries the current SIM lock status and remaining number of unlock
attempts.
- When the MT's SIM lock is locked permanently, no matter that the MT's SIM card is
locked or not, 3 is returned for <status>.
- When the MT's SIM lock is removed permanently or the MT's SIM lock is disabled, no
matter that the MT's SIM card is locked or not, 2 is returned for <status>.

13.10.2 Interface Description
When a voice test is performed for the module, the voice frequency response curve varies by
the speaker and microphone, resulting in different voice qualities. To facilitate the frequency
response curve test, AT^PCMFR is used to modify the NV of the curve and ensure the voice
quality.
This command is used to set and query the NV value of the frequency response curve.
The set command sets NV values.
The read command queries the current NV value.
The test command returns the string length of the frequency response.
13.10.3 Parameter Description
<string>: a character string indicating the NV value of the frequency response curve. Each
character can be '0'–'9', 'a'–'f', or 'A'–'F'.
<length>: an integer type value indicating the number of characters in one character string.
The number of characters is 232.

For example, the "03" value indicates LTE only.
- The "030201" value indicates the order of LTE->WCDMA->GSM.
- The "0302" value indicates the order of LTE->WCDMA, without GSM.
- The "030402" value indicates the order of LTE->CDMA->WCDMA.
- In specialty, the "99" value is not combined with other values, indicating no change of
the network access order.
- The "00" value is not combined with other values, indicating automatic network access
order that is determined by the module.
UMTS contains TD-SCDMA and WCDMA.
- If the module supports WCDMA and does not support TD-SCDMA, and then "02" means WCDMA
only.
- If the module supports TD-SCDMA and does not support WCDMA, and then "02" means
TD-SCMDA only.
- If the module supports both TD-SCDMA and WCDMA, and then "02" means TD-SCDMA and
WCDMA, and TD-SCDMA is prior to WCDMA.
- The AT^SYSCFGEX command does not support setting and querying the TD-SCDMA bands.
In case that <acqorder> is a combination list with muti-network, currently, HUAWEI products

15.4.2 Interface Description
This command queries the service provider name and the information contained in the EFSPN
file of the SIM card.
If the service provider's short and long names is released from the network side in
GMM/MM/EMM information, the MT must run the ^EONS: 0 command for unsolicited
reporting to the TE.
<type> specifies the query type. Its value can be 1, 2, 3, 4, or 5 in 3GPP mode and only 1 in
3GPP2 mode.
- When <type> is set to 1, 2, 3, or 4:
− The command format is AT^EONS=<type> or AT^EONS=<type>,<plmn_id>. If
<plmn_id> is not included, information about the current registered network is
returned.
− In the response, <plmn_name1> indicates the long name, while <plmn_name2>
indicates the short name. The value of <plmn_name1> or <plmn_name2> contains
a maximum of 128 hexadecimal characters (32 valid characters). If a name exceeds
the maximum length, the first 128 characters are retained. If <plmn_name1> or
<plmn_name2> cannot be obtained, its value is left empty.
− In the response, <spn_cond> and <spn> are handled as follows: If the SIM card for
the current registered network has an EFSPN file that is not empty, the content of the
EFSPN file is returned. Otherwise, nothing is returned.
- When <type> is set to 5:
− The command format is AT^EONS=<type> or
AT^EONS=<type>,,<plmn_name_len>. If <plmn_name_len> is not included, its
default value is used.

− In the response, the maximum number of hexadecimal characters that can be
contained in the value of <plmn_name1> is the value of <plmn_name_len> divided
by 4. An empty value is returned for <plmn_name2>.
− The response does not need to contain <spn_cond> or <spn>.
A UCS2 hexadecimal character string is converted using the big-endian encoding scheme. For
example, character 'A' is represented by 0041.
15.4.3 Parameter Description
<type>: specifies operation type.

15.5.2 Interface Description
This command queries and reports the signal strength of the current service network. If the
MT is registered with multiple networks in different service modes, you can query the signal
strength of networks in each mode.
No matter whether the MT is registered with a network or not, you can run this command to
query the signal strength or allow the MT to unsolicitedly report the detected signal strength if
the MT camps on the network. If the MT is not using any service network or the service mode
is uncertain, "NOSERVICE" will be returned as the query result, and MT will not
unsolicitedly report "NOSERVICE".
The read command queries the current network signal strength detected by the MT.
The test command returns the list of service modes supported by the MT.
The URC command allows the MT to unsolicitedly report the current signal strength when the
strength changes.

15.13.2 Interface Description
This command obtains the list of cells in the specified network mode and at the specified
frequency. In the list, cells are displayed by signal strength in a descending order.
The test command returns the supported number of cells, thresholds, and network modes.
During the process of obtaining frequency information, you can enter an interrupt character
string to interrupt the process. If interrupted, the module will output the information of found
frequencies and "OK" (not affected by the settings of NV
en_NV_Item_AT_ABORT_CMD_PARA). The interrupt character string can be set using NV
en_NV_Item_AT_ABORT_CMD_PARA. If it is set to any ASCII code, the process can be
interrupted by any character string.
Execution of this command will be interrupted by voice calls, frequency lock, TCP/UDP,
location area updates, and route area updates.
This command cannot be executed if the frequency lock is enabled, regardless of the network
mode. The cell lock will not affect execution of this command.
The maximum execution time of this command is 2 minutes.
Limitations:
1. When the module does not reside in a TD-SCDMA cell but performs the NETSCAN
operation to scan TD-SCDMA frequencies, the module will be disconnected from the
network. When the NETSCAN operation is complete, the module will reconnect to the
network. This limitation also applies to the LTE cell.
2. When the NETSCAN operation is complete, the module may not be able to reside in the
cell that it resided before the NETSCAN operation.
3. When the NETSCAN operation is complete, the module may report the service status
again and may not be able to restore to the pre-NETSCAN operation service state.
4. When the module resides in a GSM cell and performs the NETSCAN operation to scan
WCDMA frequencies, the network connection and service status does not change. If the
frequency settings specified for scanning conflict with the frequency settings specified
by AT^SYSCFGEX, an error response will be returned for AT^NETSCAN. This
limitation also replies to the case where the module resides in a WCDMA cell and scans
for GSM frequencies.

TCP/IP Protocol Stacks and AT Interfaces
Internet services refer to data services based on built-in TCP/IP protocol stacks of terminals. A
user can deliver AT commands to terminals to establish an IP/PPP link for user data
transmission. This chapter describes the AT commands related to the Internet services.
Services related to built-in protocol stacks are limited to physical ports.

16.1.2 Interface Description
This command has the same dialing function as a modem.
This command configures basic parameters for dialing and establishes connections with
networks. A local IP is obtained after the command is run. Only after network connections are
established by running the AT^IPINIT command, you can perform further operations such as
opening the TCP links and transmitting UDP data.
Aborting AT^IPINIT will not abort the PDP activation operation. It will only abort the AT^IPINIT
command to allow other AT commands to be run. But if any new AT commands about IPStack are run
when the PDP deactivation operation is in progress, +CME ERROR: 1042 ("PDP operation in progress,
please wait.") will be reported.
16.1.3 Parameter Description
<APN>: a string type value with quotation marks that indicates the access point name, with a
maximum of 99 characters, as shown in the example. (If only comma is specified or no
character is specified, it indicates that APN is null)
<user_name>: a string type value with quotation marks, with a maximum of 31 characters,
which can be left out.
<password>: a string type value with quotation marks, with a maximum of 31 characters,
which can be left out.
<ip_addr>: a string type value with quotation marks, with a maximum of 40 characters. This
parameter can be set to a static IPv4 address by a request. However, an actual IPv4 address
may be obtained for this parameter.
<auth_type>: indicates the authentication mode.

16.7.2 Interface Description
This command transfers the command mode of a physical port where a link locates to data
mode. In data mode, all the data input except the +++ command for exiting the data mode is
transmitted as user data. This command returns OK if it runs successfully, and then the user
can receive and send data in data mode.
If a user enters three consecutive signs (+++), the physical port exists the transparent
transmission mode.
Requirements of the three consecutive plus signs are detected as follows: No data is input 900
ms before the three consecutive plus signs are entered. The time interval between two '+' input
must be less than 900 ms. No other data is required 900 ms after the third plus sign is entered.
The twelfth parameter of the AT^IPCFL command sets the transparent transmission mode of a
UDP link to mode 0 or mode 1.
In mode 0, the module sends any data from the host computer to socket as user data, and
determines delay and timing of the assembled data packets and data packet sending length
based on parameters 5 and 11 of AT^IPCFL.
In mode 0, data is sent as follows:
- If the length of the data received from the host computer reaches the data packet sending
length, the module sends the data to socket and continues to process the data.
- If the length of the rest data received from the host computer does not reach the data
packet sending length, the module starts or resets the packet delay timer.
- If the timer expires, the module sends the rest data to socket.
- If the module receives new data from the host computer when the packet delay timer is
running, repeat steps 1 to 3.
In mode 1, the host computer needs to add the 0x7E end character for each data packet of the
user data. If the module detects 0x7E, the module considers that a data packet ends and then
sends it to socket. Therefore, end characters of the user data need to be escaped. That is, the
host computer needs to check all the user data and convert their end characters. The module
then escapes the converted end characters to the original characters and sends the original
characters to socket.
The escape rule of the user data to be sent is as follows: The 0x7E end characters contained in
the user data are escaped as the 0x7D 0x5E end characters. The 0x7D end characters
contained in the user data are escaped as the 0x7D 0x5D end characters.
At the same time, the host computer needs to process the data received from the module. The
host computer escapes the 0x7D 0x5E end characters to the 0x7E end characters, and escapes
the 0x7D 0x5D end characters to the 0x7D end characters. The 0x7E end characters indicate
the end of a UDP packet and are not the actual user data. Mode 0 is applicable to sending and

16.8.2 Interface Description
This command sends the user data based on established links. Among three data sending
modes available, mode 2 is recommended.
- Mode 0 is compatible with the AT^IPSEND functions backwards.
- Mode 1 is a mandatory data conversion mode. In this mode, the original data requested
by a user to be sent must be converted from hexadecimal digits to character strings. After
the character strings are converted to the original data, the module sends the original data
to the peer. For example, the user can enter the AT^IPSENDEX=1,1,"01081B2C"
command to send the quartet data: 0x01, 0x08, 0x1B, and 0x2C. The receiving end will
receive the quartet data.
- Mode 2 is a length-limited full-character mode. In this mode, the user sends a command
to notify the module of the length of the data to be sent first. After the module returns
OK, the user enters data until the data length reaches the requested length.
- If the length of the input data is less than the expected length, the module waits for the user to enter
the rest data.
- If the length of the input data is greater than the requested length, an error is returned.
16.8.3 Parameter Description
<link_id>: indicates the ID of established links. The value ranges from 1 to 5.
<mode>:
0

1
Mandatory data conversion mode
2

<data>: indicates user data with quotation marks. The maximum length of the user data is
1500 characters in both mode 0 and mode 1.
<len>: indicates the maximum length of the data requested by a user to be sent, which cannot
exceed 1500 characters.
<eof>: indicates the end of the user data during FTP put.
0
Data is pending.
1
End of file or data
It is suggested that the user data be sent over a TCP link with the <MSS> value being the maximum
length. Otherwise extra packets are generated, affecting the transmission rate. For example, if the
<MSS> value is 1460, 1460 characters are recommended for the maximum length of <len>.

16.9.2 Interface Description
When data is sent over a TCP link, the peer end, if it receives the data, sends ACK to the
sending end. After the ME receives the ACK from the peer end, the ME confirms that the data
is successfully sent.
No ACK is required when data is received or sent over a UDP link. Only the sums of the data
packets sent to and received from the peer end are recorded.
The set command clears the data packet statistics of the designated TCP/UDP link, including:
- Uplink: the sum of the data packets received from the host computer, and the sum of the
data packets sent to socket, the sum of the confirmed data packets.
- Downlink: the sum of data packets received from socket and the sum of data packets sent
to the host computer
The read command queries the data packet statistics of all current TCP/UDP links.
The test command returns the sequence number of the supported TCP/UDP link.
16.9.3 Parameter Description
<link_id>: an integer type value that indicates the TCP/UDP sequence number.
0
Indicate clearing the statistics of all TCP links.

The read command queries the current priority of voice call and data service.
16.15.3 Parameter Description
<mode>:
0
Voice call prefer (default value)
In this state, an incoming voice call will suspend the data transmission. If data
service is not in transparent transmission mode, all ports (PCUI port, MODEM port,
and UART port) will report RING message. If data service is in transparent
transmission mode, all ports will report RING message except the port which is
processing data service, and the RING pin is dredged. The data transmission will
keep on going after stopping the voice call. But there is one risk that the transmitted
data maybe loss during the process of voice call, only the last packet (less than 1600
byte) can be sent successfully
1
Data service prefer
In this state, When the TE performing IP Stack asynchronous command or in the
transparent transmission mode, an incoming voice call will be hung up by the
module automatically.
In this state, the TE can originate a voice call. And a new incoming voice call during
the call will not be hung up automatically.
To change the priority of voice call and data service, you can use AT^DVCFG=0 command,
or AT^IPCLOSE=7 to close IPSTACK, which can return back to answer the voice call when it
coming.

16.21.2 Interface Description
This command is used to manage certificates and other security data like private key.
Brief information about AT^SSLMNG command:
- Certificates must be in PEM format.
- For large size of certificate (greater than 1024 bytes), we have to break the certificate
data into packages and maximum size of each package is 1024 bytes.
- Each package should have the unique identification number (1–10).
- It supports up to 10 kb (10 * 1024) size.
- Packages can be given by any order in AT^SSLMNG command.

OK
- After giving all the packages, the SSLMNG will integrate all the packages and do the
Base 64 decoding and finally store/delete/load the file into/from file system.
- If any error appears in any one of the package, then all previously received packages will
be cleared.
- If the module starts to execute any of the SSLMNG operation with multiple packages,
before completing that operation (before giving all the packages), any other operation
cannot be executed in AT^SSLMNG.
The read command queries the name of files (certificates) stored in the file system. When the
module is powered off and reset, the last operation of SSLMNG will not be saved. When the
certificate is not completely stored, the return of AT^SSLMNG? will not contain the file name
of certificate and key.
The test command returns the SSL manage command capability.
Only the following encryption types are supported for password protected encrypted certificates.
- DES-CBC
- DES-EDE3-CBC
- AES-128-CBC
- AES-192-CBC
- AES-256-CBC
16.21.3 Parameter Description
<SSL_id>: an integer indicates the SSL socket ID.
1
Secure socket connection
2
FOTA secure socket connection.
<data_type>: an integer indicates the certificate or key to be stored.
0
Certificate of the client (the module). It is needed when the server or client
authentication mode has been configured.
1
Root CA certificate of the remote server used to authenticate the remote server. It
is needed when <scur_level> of AT^SSLCFG is set to 1 or 2.
2
RSA private key of the client (the module). It is needed if the server or client
authentication mode has been configured.

Load certificate
<file_name>: the file name for "". The maximum length of the file name is 255.
<package_id>: package identification number. The value ranges from 1 to 10.
<total_no_of_packages>: total number of packages after splitting the Base 64 encoded format
certificate data of each package, of which the maximum size is 1024 bytes. The value ranges
from 1 to 10.
<cert_info>: a string type indicates the broken certificate package (converted into Base 64
encoded format before splitting the package) data. The length ranges from 1 byte to 1024
bytes.
<password>: a string type indicates the password for private key (the length ranges from 4
bytes to 80 bytes) plain text.
- <package_id>, <total_no_of_packages> and <cert_info> are optional if <action> is 1 or 2.
- <password> is applicable only if <action> is 2 and when loading the private key with password.
- It is not required to give the password in every package, but the last package must contain the
correct password.
- For FOTA SSL, it is required to give the password in every package, but the last package must
contains the correct password.
<list_of_file_names>: the name of the files stored in file system.
- On "Delete" action, currently the certificate is only deleted from the file system. To delete from SSL
library context, socket needs to be disabled and re-enabled again.
- If more than one client and key certificates are available in the file system, then users need to load
the corresponding certificate by using AT^SSLMNG command with the <action> as 2 (reading data)
to succeed the hand shake during the open socket.
- AT^SSLMNG for <action>=0 (storing data) can store a maximum of 10 certificates (10 each for
ca-cert, client cert and client key) in the file system beyond which it would display error "Certificate
maximum limit reached".
- AT^SSLMNG for <action>=2 (reading data) can load a maximum of 10 certificates from the
buffer/file system during a particular session beyond which it would display error "Certificate
maximum limit reached".
- AT^SSLMNG? command would display first 10 certificates stored in the file system for each type
(CA, Client, Private Key) of certificates.
- Usage of <password> parameter is applicable in case of "Load" of "Private Key" during client
authentication and it is required to set the password if the private key is encrypted. So this password
parameter is an optional parameter.
- Certificate store/delete operations will not be controlled by SSL enabled or disabled.
- On FOTA SSL connection, RAM storing is not supported. Users have to store the certificate first and
then use LOAD operation to load the certificate.
- FOTA SSL socket connection (<SSL_id>=2) store/delete/load operations will not be controlled by
SSL enabled or disabled.

16.25.2 Interface Description
This command is used to receive the data through the secure or normal socket.
The test command returns the SSL received command capabilities.
- For the Sync mode (if the socket is opened with <mode>=0), AT^SSLRX will work in
the synchronous mode. If AT^SSLRX command is run, the module will receive the data
from the server.
- For the ASync mode (if the socket is opened with <mode>=1), AT^SSLRX will work in
the asynchronous mode. Whenever the data is available in the server, the module will
receive the data automatically.
- In the Sync mode, if the server sends data that exceeds the maximum length, AT^SSLRX
can be executed to read the entire data.
- In 2G network, AT^DVCFG can be used to set the priority of call or data.
If the AT^SSLRX operation time exceeds the preset threshold, a timeout occurs.

If you want the module to discard the server-sent packet which content is "123"(0x313233) and do not
report it, you can set the <ACK data> as either "123" or "3132333". But when you set the <ACK data>
as "313233", the wake-up packet that server sent should avoid being set as "313233"(0x333133323333)
because both the strings "313233" and "123" will be discard.

This command configures basic parameters for dialing and establishes connections with
networks. A local IP is obtained after the command is run. Only after network connections are
established by running the AT^IPINITEX command, you can perform further operations such
as opening the TCP links and transmitting UDP data.
Aborting AT^IPINITEX will not abort the PDP activation operation. It will only abort the AT^IPINIT-
EX command to allow other AT commands to be run. But if any new AT commands about IPStack are
run when the PDP deactivation operation is in progress, +CME ERROR: 1042 ("PDP operation in
progress, please wait.") will be reported.
When using AT^IPINITEX to dial both IPv4 and IPv6, the return value of OK does not mean that both
ipv4 and ipv6 have been dialed. Before issuing AT^IPOPEN to open a link, you should ensure that your
device has obtained the address you want to use.
16.31.3 Parameter Description
<channel_id>: channel ID. Currently, the channel ID can only be set to "1".
<PDP_type>: Character string type, which specifies the dialing type.

actual maximum valid length is 63 characters.
<user_name>: Character string with double quotation marks not exceeding 31 characters and
can be omitted.
<password>: Character string with double quotation marks not exceeding 31 characters and
can be omitted.
<auth_type>: This parameter indicates the authentication mode, which can be omitted. If this
parameter is omitted, the default value is used.

20.5.2 Interface Description
Locally save a group of usernames and passwords, etc. indexed by <cid>, and each one
contains a set of saved settings environmental parameters associated with the handshake
agreement.
The set command stores a set of parameters of the handshake protocol to a group of data
storages indexed by <cid>. Each data storage is initially undefined, after a set of parameters
stored into by the set command, the data storage then becomes a defined state. And the
number of defined data storages can be saved is determined by the value range of <cid>.
A special set command AT^AUTHDATA=<cid>, will clear stored parameters indexed by
<cid>. Then this data storage returns to an undefined state.
The read command queries all defined parameter values, and each group of handshake
agreement data displays in a line.
The test command returns all supported values.

22.2.2 Interface Description
The set command enables or disables the TTS function. TTS converts GBK character strings
into voice, which is played through the voice channel. If TTS is disabled, voice is not played.
The set command cannot be issued again until the ^AUDEND command, which indicates that
the audio playback ends, is reported. This command is affected by the TTS protection
function. On modules that do not support TTS, TTS protection is enabled, and ERROR will
be returned when this command is executed.
After this command is executed:
- When a voice call is set up, voice is played on the receiving end.
- When a voice call fails to be set up, a new call comes in, or recording is in progress, an error
message is returned.

23.8.3 Parameter Description
<timestamp>: a string type value that specifies the time when the IVS receives the AL_ACK
sent by the PSAP. Format: "yyyy/mm/dd,hh:mm:ss±zz". <timestamp> indicates the internal
system time of the module. The value of yyyy ranges from 2000 to 2100. The minimum unit
is second.
<AL_ACK>:
0
The PSAP confirms that the MSD data have been verified.
2
The PSAP confirms that the MSD data have been verified and requires the IVS to
hang up the eCalls.
As the PSAP sends AL_ACKs at a very short interval, AL_ACKs may be reported at the same
time.
The PSAP sends the AL_ACK to the IVS when the PSAP receives and successfully verifies
the MSD data. The AL_ACK with a clear-down mark requests the IVS to hang up the eCall.
The received AL_ACK contains only the following bits:
Bit 4
Reserved (currently 0)
Bit 3
Reserved (currently 0)
Bit 2
Status - 0 (Positive ACK), 1(Clear-down)
Bit 1
Format version - 0/1 of the format version (currently 0)
That is, only the last four bits of the AL_ACK are valid. Bit 2 has two options and other bits
are all 0. For details, refer to section 7.5.5 in EN 16062:2013 protocol.

(exclude <file_type>). If files already exist, they are replaced directly, and no error
is returned.
<para1>: an integer type value indicating a packet number, which is used to save or
read recording files. If <mem> is 0 (RAM), the <para1> has a value range of 1–120;
else if <mem> is 1 (Flash), the value range is 1–600.
<para2>: an integer type value indicating the total number of packets, which is used
to save or read recording files. If <mem> is 0 (RAM), the <para2> has a value range
of 1–120; else if <mem> is 1 (Flash), the value range is 1–600.
3
Indicate the delete operation.
When <mode> is set to 3, the AT^FILEIO command only needs to include <mode>
and <file_name>.
<file_name>: indicates the file name with quotation mark.
This command is used to save or read recording files, which are named RAM, REC1.AMR,
EC2.AMR, REC3.AMR, REC4.AMR, and REC5.AMR. To ensure the file integrity, send one
file only after the previous one is completely sent. Otherwise, an error will be returned. If you
want to change the file that is being sent, use the delete operation to delete the file.
<mem>: an integer indicating the storage media.
0
RAM. Only one file can be saved, and its name is fixed at "RAM". This file is not
saved upon a power-off. For the recorded file access function, the maximum size
of each file is 60 KB.
1
Flash memory. Multiple files can be saved, and they are saved upon a power-off.
For the recorded file access function, a maximum of five files can be saved, and
each file's size does not exceed 60 KB.
<file_type>: an integer indicating the type of files. The value ranges from 0 to 255. This
parameter helps to distinguish various files for a product that supports the function to
download these files. (not supported currently)
<pkg_data>: indicates packet data with the quotation mark. The value is in the format of
ASCII characters with a range of '0'–'9' and 'A'–'F'. If the data (without the quotation mark) is
empty or has a length over 1024, an error is returned.
The hexadecimal code data of each byte in the uploaded file is converted into two-byte ASCII characters.
For example, 0x65 is converted into 65.)
<rcv_len>: an integer indicating the length of the received data in bytes.
<file_size>: an integer indicating the total length of the data in bytes.
<file content>: the contents of the data, containing double quotation marks. The value is a
string of ASCII characters, ranging from '0' to '9' and 'A' to 'F'. The maximum length of data
(without the double quotation marks) is 512 bytes. The encoded contents with the double
quotation marks are converted into ASCII characters, and the total length cannot exceed 1024
bytes.

- If data is stored in RAM, the offset value must be set to 0. Otherwise, an error is returned.
- If the file to be deleted does not exist, OK is returned.
- The host sends 0x32 to the module, the module will just save 0x32. But AT^FILEIO needs to display
the data, all characters will be encoded to ASCII. The ASCII codes of '3' and '2'are respectively "33"
and "32", so the content of AT^FILEIO is 0x33 0x32. And the maximum length of each packet is
512 Bytes, if you need to write 300 KB data to the module, the host should totally send 600 packets.
- When AT^FILEIO is used to write data, the data must have AMR file header. If not, the module will
consider the data is illegal and response +CME ERROR: 65290 (amr file header lost).
