1 Introduction

1.1 Introduction to Interface between TE and MS

In order to communicate each other between TE and MS, we must use AT commands.

Figure 1.1 illustrates the interface. In addition, we will describe about SIM, list

management, mobility management, call control, supplementary service, short

message, cell broadcast, base-band and the other service in next section.

Figure 1.1

1.1.1 Explanation

Command Possible response(s)

ME Mobile equipment

MS Mobile station. Basically, a mobile station is mobile equipment with a SIM card.

TE Terminal Equipment that is the same as the controller in this case.

1.1.2 Getting started

For testing AT commands, the MS can be connected to any computer environment,

as long as it has a V.24/V.28 serial interface. The commands can be issued with, for

example, HyperTerminal in Microsoft Windows or other emulator programs.

1.1.3 Syntax description

This section gives a brief description of the syntax used for the command set. The MS

may echo characters which is received, depending on the setting of the command E.

As a default, echo is enabled. In addition, the received characters are echoed by

the same rate, parity, and format.

The character defined by parameter S5 (default, BS, IRA 8) is interpreted to be a

request from the TE for deleting the previous character.

TE MS

AT COMMAND

M7-21-0010-121 - 14 - Version: 1.2.1 – 2010/12/30


Command Possible response(s)

<CR> Carriage return character, whose value is specified by command S3, default IRA 13.

<LF> Line feed character, whose value is specified by command S4, default IRA 10.

<…> The name enclosed in angle brackets is a syntactical element. The brackets do not appear in the command line.

[…] Strings enclosed in square brackets are optional items (sub-parameters). The brackets do not appear in the command line.

Other characters, including ‘?’,’=’, parentheses, etc, appear in commands and

response as written.

1.1.4 AT command syntax

A command line is composed of three elements: the prefix, the body and the

termination character. The prefix part starts from the characters ‘AT’ and follows by

basic syntax command (eg: ATV1), or by a plus sign (+) together with extended

syntax command (eg: AT+CFUN=1) which MS supports as well.

Basic syntax command

The format of basic syntax commands, except for the command D, is as follows:

<name>[<value>]

Example:

� ATV1

Extended syntax command

+<name>[=<value>]

Example:

� AT+CMUT=0

Test command syntax

+<name>=?

Example:

� ATS3=?

Read command syntax

+<name>?

Example:

� AT+CACM?

If the indicated name is not recognized, an Error code is issued.

The <response> can be:

� Basic format result code

� OK

� Extended syntax result code, prefixed with a plus sign (+)

� +<name>: <value>

The result codes will be separated by commas if it includes several values. The

<value> followed by the colon is separated by a space. It is also possible that result

codes have no value. Unlike basic format result codes, extended syntax result codes

have no numeric equivalent, and are always issued in alphabetic form.

There are two types of result code responses:

Final result code

A final result code indicates to the TE that execution of the command is completed

and another command may be issued.

If you type an implemented AT command, you should get the result code OK.

If you type an AT command which is not ready for users, or the parameter or syntax

you provide is wrong, you will get the result code ERROR or something else, for

example, +CME ERROR followed by an error code.

Unsolicited result code

Unsolicited result codes, such as RING, indicate that the occurrence caused by an

event is not directly associated with a command which is issued from TE.

2.9 A/: Repeating a command line

If the prefix "A/" or "a/" is received, the DCE will immediately execute the body of the

preceding command line once again. No editing is possible, and no termination

character is necessary. A command line may be repeated multiple times through this

mechanism, if it is requested. Responses from the repeated command line shall be

issued using the same parity and format as the original command line, and the same

rate of the "A/". If "A/" is received before completely executing any command line,

the preceding command line is assumed to be empty (that results in an OK result

code).

Syntax

2.10 Z: Reset to default configuration

This command instructs the DCE to set all parameters to their factory default values

specified by the manufacturer. Moreover, the settings of hardware configuration

switches or non-volatile parameter storage (if it is implemented) may be took into

consideration as well. If the DCE is connected to the line, it will be disconnected and

will terminate any call in progress once ATZ command is executed.

All functions of the command shall be done completely before the DCE issues the

result code. The DTE should not include additional commands on the same

command line after the Z command; otherwise, these extra commands may be

ignored.

An OK result code for this command is issued using the same rate, parity, and format

as the DTE command line that contains the command, but the different new values

for parameters that affect the format of result codes (e.g. Q, V, S3, S4).

2.18 S3: Command line termination character

This S-parameter represents the decimal IA5 value of the character recognized by the

DCE from the DTE for terminating an incoming command line. It is also generated by

the DCE as part of the header, trailer, and terminator for result codes and information

text, along with the S4 parameter (see the description of the V parameter for usage).

The previous value of S3 is used to determine the command line termination

character for the entry of the command line which contains the S3 setting command.

However, the result code issued will base on the value of S3 set during the process of

the command line. For example, if S3 was previously set to 13 and the command line

“ATS3=30” is issued, the command line shall be terminated with a CR character (IA5

0/13), but the result code issued will use the character with the ordinal value 30 (IA5

2/14) in place of the CR.

2.25 &C: Circuit 109 (Received line signal detector) behavior

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 &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 has to be turned off if the DTE turns off circuit

108 (if &D1 or &D2 is set).

Syntax

AT&C[<value>]


Parameter(s)

<value> Numeric

0 The DCE always presents the ON condition on circuit 109.

1 Circuit 109 changes in accordance with the underlying DCE, which may include functions other than the physical layer functions (e.g. Recommendation V.42, V.110, V.120 and V.13).

2.26 &D: Circuit 108 (Data terminal ready) behavior

This parameter determines how the DCE responds when circuit 108/2 is changed from

the ON to the OFF condition during online data state.

Syntax

AT&D[<value>]


Parameter(s)

<value> Numeric

0 DCE ignores circuit 108/2.

1 Upon an on-to-off transition of circuit 108/2, the DCE enters online command state and issues an OK result code; the call remains connected.

2 Upon an on-to-off transition of circuit 108/2, the DCE instructs the underlying DCE to perform an orderly clear down of the call. The disposition of any data in the DCE pending transmission to the remote DCE is controlled by the ETBM parameter 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 answer is disabled while circuit 108/2 remains off.

2.27 +IPR: Fixed DTE rate

This command, the numeric extended-format parameter specifies the data rate

which the DCE will accept. in addition to 1200 bit/s or 9600 bit/s. It may be used to

choose operation with the rates which the DCE is not capable of automatically

detecting the data rate that is being used by the DTE. Specifying a value of 0 disables

the function and allows operation only at rates which can be automatically detected

by the DCE. The specified rate takes effect according to the issuance of any result

code(s) associated with the current command line.

The rate specified does not apply to online Data State if direct mode of operation is

chose.

The rate value specified shall be calculated in bits per second for the DTE-DCE

interface to handle, e.g. "19 200" or "115 200". The rates supported by a particular DCE

are manufacturer-specific; however, the IPR parameter should permit the setting of

any rate supported by the DCE during online operation. Rates which include a

non-integral number of bits per second should be truncated to the next lower integer

(e.g. 134. 5 bit/s should be specified as 134; 45.45 bit/s should be specified as 45). If

the rate is unspecified or set to 0, automatic detection will pick up a rate. In addition,

the character format is also forced to auto-detect, ICF 0.

It is recommended that the default value for this parameter is set to be the automatic

detection setting (0), which facilitates initial DTE-DCE communications.

2.28 +ICF: DTE-DCE character framing

This extended-format compound parameter is used to determine the local serial port

start-stop (asynchronous) character framing that the DCE shall use while accepting

DTE commands and while transmitting information text and result code, if this is not

automatically determined; IPR 0 forces ICF 0. Note that the definition of fixed

character format for online data state is for further study.

Format determines the number of bits in the data bits, the presence of a parity bit,

and the number of stop bits in the start-stop frame.

2.30 +ILRR: DTE-DCE local rate reporting

This extended-format numeric parameter controls whether or not the

extended-format "ILRR: rate" information text is transmitted from the DCE to the DTE.

The rate reported shall represent the current DTE-DCE rate. If it is enabled, the

intermediate result code is transmitted after any modulation, error control or data

compression reports are transmitted, but before any final result code (e.g. CONNECT)

is transmitted. The rate is applied after the final result code is transmitted.

The DTE-DCE port rate will only be changed under the situations of (1) neither

3.9 D: Dial

This command instructs the DCE to create a call. This may include several steps,

depending upon the DCE type, such as: connecting to the line (going off-hook),

waiting for the network to indicate readiness to receive call addressing information

(wait for dial tone), signaling call addressing information to the network (dialling the

number), monitoring the line for call progress signals (e.g. busy), and instructing the

underlying DCE to start the call procedure (modulation handshaking).

All characters follow the "D" and up to a semicolon character (IA5 3/11) or the end of

the command line are considered to be part of the call addressing information and

be signaled to the network, or to be modifiers used for controlling the signaling

process (this is known as a "dial string"). If the dial string is terminated by a semicolon,

the DCE does not start the call procedure defined for the underlying DCE, but returns

to command state instead after signaling the call addressing information to the

network.

Any characters within the dial string that the DCE does not recognize as a valid part

of the call addressing information or a valid modifier shall be ignored. This permits

characters such as parentheses and hyphens to be included since they are typically

used as part of the telephone numbers.

Syntax

<text> Connection status String

M7-21-0010-121 - 72 - Version: 1.2.1 – 2010/12/30


3.10 W: Wait for dial tone

This causes DCE to listen to dial tone on the line. If a valid dial tone is detected, the

DCE continues processing the remainder of the dial string.

If DCE decides to abort dialing because the dial tone does not occur within the

connection timeout period specified by parameter S7, the NO DIALTONE or NO

CARRIER result code is issued and the remainder of the command line is ignored.

The DCE may, but is not required to, detect busy signal while listening to dial tone. This

capability may be conditioned upon the setting of the X command. The BUSY or NO

CARRIER result codes may be issued if the DCE detects a busy signal while listening to

dial tone; in this event, the remainder of the command line is ignored.

however, it is recommended that the DTE explicitly specify pulse or DTMF dialing with

an appropriate dial modifier (P or T) at the beginning of each dial string.

4.16 +CPOL: Preferred PLMN list

This command is used to edit the PLMN selector with Access Technology lists in the SIM

card or active application in the UICC(GSM or USIM).

Execute command writes an entry in the SIM/USIM list of preferred PLMNs previously

selected by the command +CPLS. If no list has been previously selected, users will

control PLMN selector with Access Technology, EFOPLMNWACT, which is the default

one considered.

If <index> is provided but <oper> is not, entry is deleted. On the other hand, <oper> is

put into next free location if <oper> is provided without <index>.

If only <format> is provided, the format of the <oper> in the read command will be

changed.

The Access Technology selection parameters makes Read command return all used

entries from the SIM/USIM list of preferred PLMNs previously selected by the command

+CPLS with the Access Technologies for each PLMN in the list.

Note: It is recommend to add a preferred PLMN with numeric format. There is an

internal list which stores all PLMNs’ long names, short names and numeric names in

the module. AT+COPN is able to display the list. The numeric information is the MCC

and MNC of the PLMN. Once long/short format is chose for inserting a preferred PLMN

that does not exist in the internal list, the module will reject the command because of

it’s failing to get the MCC and MNC of the PLMN.

Test command returns the whole index range supported by the SIM.

5.6 +CRSM: Restricted SIM access

By using this command instead of Generic SIM Access +CSIM TE application will be

easier but have more limitation to access the SIM database. Set command transmits

the SIM <command> and its required parameters to ME. ME internally handles all

SIM-ME interface locking and file selection routines. As response to the command, ME

sends the actual SIM information parameters and response data. ME error result code

+CME ERROR may be returned when the command cannot be passed to the SIM;

however, failure in the execution of the command in the SIM is reported in <sw1> and

<sw2> parameters.

It is coordination that commands used for requesting SIM access externally and those

issued by GSM/UMTS application inside the ME are implement-dependent. However

the TE should be aware of the precedence from GSM/UMTS application commands

to TE commands.

6.5 $SMRC: Sim Index Manually Update

For faster searching address book, module backups phone book on SIM into FFS, and

create an index for SIM. If another SIM card is inserted, module will detect the

inconsistence of IMSI and then re-create the index.

There is a scenario makes index asynchronous with SIM. If user remove a SIM card,

edit its address book on another ME, and insert it back to module, module will not

update the index because the same IMSI is detected.

Under this scenario, SIM index need to be updated manually, and AT$SMRC=1 is

suggested. This command sets a flag in FFS, and effect permanently.

Syntax

AT$SMRC=[<enable>][,<number>[,<type>[,<text>]]]

Response(s) � OK � +CME ERROR <err>

AT$SMRC?

Response(s) � $SMRC: [<enable>] OK

Parameter(s)

8 Fax Control

8.1 +FDT: Send a page

The FDT command requests the DCE to transmit a Phase C page. It is issued at the

beginning of each page, either in Phase B or in Phase D. When the DCE is ready to

accept Phase C data, it shall issue the negotiation responses and the CONNECT result

code to the DTE. Negotiation responses are controlled by the FNR sub parameters

(8.5.1.11/T.32).

In Phase B (after ATA, ATD or the end of a document), the FDT command releases the

DCE to keep processing with negotiation and releases the DCS message to the

remote station. In Phase D (after sending a page), the FDT command resumes

transmission after the end of a previous page.

The FDT command returns a positive CONNECT result code response if the DCE is

ready for data; otherwise, it will return others (e.g. FHS:<hangup code>). Following the

CONNECT message, the DTE shall deliver image data to the DCE as negotiated. After

image data is delivered, the DTE shall deliver a <DLE><ppm> a pair of characters

(8.3.3.7/T.32) to mark the end of the data and to indicate subsequent actions.

The FDT command results in an ERROR result code response if the DCE is on-hook.

Syntax

M7-21-0010-121 - 186 - Version: 1.2.1 – 2010/12/30


8.2 +FDR: Receive a page

The command initiates transition to Phase C data reception after the following

circumstances: answering, dialing, a document is received, or a page is received.

The DCE may report the negotiated T.30 parameters, with the remote ID and NSS

frame information if available. When the DCE is ready to commence data transfer, it

shall issue a CONNECT response code. After the DTE receives the CONNECT response

and the DTE is ready to accept data, it shall issue a <DC2> character (T.50 1/2) to the

DCE.

From the +FDR command to the end of Phase C Data, the DCE is in a data transfer

state and shall not respond to DTE command lines. The DCE shall respond to four T.50

control characters: <DC1> (1/1) and <DC3> (1/3) flow control characters, <CAN> (1/8)

(8.3.4.6/T.32) and to <"?"> (3/15) (8.3.4.7/T.32); all other characters are discarded.

When the DCE delivers the last octet of a page, indicated by the <DLE><ETX> stream

termination sequence, the DCE shall report the Page Status via the +FPS:<ppr>

response, described in 8.4.3/T.32 (http://www.itu.int/rec/T-REC-T/e). The Page Status is

also stored in the +FPS parameter (8.5.2.2/T.32). The <ppr> response codes are

described in Table 18.

After a Page Status is reported, the DCE shall report the post page message from the

remote facsimile station via the +FET:<ppm> response (8.4.4.1/T.32), which signals the

intentions of the remote station. <ppm> response codes are described in Table

19/T.32 (http://www.itu.int/rec/T-REC-T/e).

The DCE shall use the <ppr> code stored in the +FPS parameter to determine the Post

Page response to the remote facsimile station. The DTE may modify the +FPS

parameter before issuing the +FDR command, which releases that message. The DTE

must issue a +FDR command to release Post Page Messages.

The +FDR command shall return an ERROR result code if the DCE is on-hook or if the

capability of receiving is missed or disabled (FCR0, 8.5.1.9/T.32).

8.3 +FKS: Terminate a session, orderly fax abort

The +FKS command causes the DCE to terminate the session in an orderly manner. In

particular, it will send a DCN message at the next opportunity and hang up. At the

end of the termination process, the DCE shall report the +FHS response with result

code, defined in 8.4.5,/T.32 (http://www.itu.int/rec/T-REC-T/e), go On-Hook and set

FCLASS0 if FCLASS0 is supported.

The DTE may also invoke this operation using the T.50 <CAN> (Cancel, T.50 1/8)

character during Phase C data reception (see 8.3.4.7/T.32). If the DTE issues this

command while the DCE is On-Hook, the DCE shall report OK.

8.4 +FIP: Initialize service class 2 parameters

The +FIP command causes the DCE to initiate all Service Class 2 Facsimile Parameters

to the manufacturer who determined default settings. This command does not

change the setting of +FCLASS. This command has the same effect as if the DTE had

issued individual parameter setting commands.

This command may be issued during a session. The DCE shall use the new settings

they are sampled next time; for example, a new + FIS setting would be used next

time the DCE enters Phase B.

8.14 DCE responses, +FPS: Report T.30 phase C page reception

The +FPS:<ppr> is generated by the DCE at the end of Phase C data reception within

the execution of a +FDR command.

The initial <ppr> is generated by the DCE; it depends on the DCE for T.4 or T.6 error

checking capabilities, controlled by the +FCQ parameter (8.5.2.3/T.32). Note that the

<ppr> value may be changed by the DCE in response to a remote request for

procedure interrupt (8.5.2.2/T.32).

The receiving DCE may count lines, bad lines, maximum consecutive bad lines, and

octets lost due to DCE buffer overflow, and report them:

<lc>: line count;

<blc>: bad line count;

<cblc>: maximum consecutive bad line count; this is the number of lines in the largest

group of consecutive bad lines;

<lbc>: lost octet count.

The line counts are qualified by the DCE’s copy quality checking capabilities,

controlled by the +FCQ parameter (8.5.2.3/T.32). If the DCE is not configured to count

lines, or if line counts are irrelevant (e.g. in Binary File Transfer mode,

Recommendation T.434) the DCE shall set the line counts to 0.

A receiving DTE may inspect <ppr>, and write a modified value into the +FPS

parameter. The DCE shall hold the corresponding Post Page Response message until

it is released by a subsequent +FDR command from the DTE.

8.32 +FIE: Procedure interrupt enable

This command decides the operation upon receipts Procedure Interrupt Requests

from remote station.

For transmission (+FDT), Procedure Interrupt Requests from the remote station are not

reported directly; only the +FVO response is reported.

For reception (+FDR), Procedure Interrupt Requests from the remote station are

reported in the +FET: response. The value stored in the +FPS parameter will be

adjusted to 4 or 5. If the DTE issues a subsequent +FDR command with the +FPS value

intact, the DCE will complete the negotiation and issue a +FVO response.

Syntax

M7-21-0010-121 - 221 - Version: 1.2.1 – 2010/12/30


8.33 +FPS: Page status

The +FPS parameter which contains a value represents the post page response, and it

also includes copy quality and related end-of-page status. These values correspond

to post page response messages defined in Recommendation T.30. The receiving

DCE sets this parameter after it receives a page of Phase C data. The transmitting

DCE sets this parameter with the status reported by the receiving station. The DTE may

inspect or modify this parameter.

Valid <ppr> is defined below. Its value is also reported by the +FPS:<ppr> response to

the +FDR command (8.4.3/T.32).

The DCE may set this parameter to values 1, 2 or 3 based on its own copy quality

checking or access to received signal quality. The DCE shall set this parameter to a

value of 1 if copy quality checking is disabled (+FCQ=0, see 8.5.2.3/T.32).

Copy quality checking is the responsibility of the DCE. However, a receiving DTE may

do its own Copy Quality checking.

The DTE may request a Procedure Interrupt from the remote station using this

parameter. To do so, the DTE shall modify the value reported by the DCE before it

issues the next +FDR command, which in turn instructs the DCE to send the resulting

post page response to the remote facsimile station.

8.34 +FCQ: Copy quality checking

The +FCQ compound parameter controls copy quality checking and correction by a

facsimile DCE. The <rq> subparameter controls copy quality checking and correction

of data which is received from the remote station and delivered to the local DTE; the

<tq> subparameter controls copy quality checking and correction of image data

which is received from the local DTE and sent to the remote facsimile station.

For any data type supported, DCE is responsible for Receive Copy Quality Checking.

However, the DTE may turn off copy quality checking by setting +FCQ=0,0, or by

setting +FND=1.

Copy quality checking consists of determining if the incoming image data conforms

to the negotiated standard format, e.g. Recommendation T.4 or T.6. Copy quality

correction consists of detecting errors and altering the data in some way to

guarantee that only valid data (according to negotiated parameters) is delivered.

The methods used for copy quality checking or for correction are not a subject of T.32.

The DCE may use the associated T.30 control parameters to condition its Copy Quality

Checking behavior. Common procedures for Copy Quality correction include

deletion of bad lines or replacement of bad lines by previous good lines.

The DCE shall report on Received Copy Quality to the DTE in the page status report,

+FPS:<ppr>,<lc>,<blc>,<cblc>,<lbc>, and record it in the +FPS parameter.

8.35 +FRQ: Receive quality checking

The DCE may use this compound parameter to make the "Copy Quality OK" decision

in the T.30 flow chart (Figure A.7/T.30). If this is used, the DCE shall judge Copy Quality

that is unacceptable if either the percentage of good lines is too low or too many

consecutive lines contain errors. Bad line counts are reported in the +FPS:<blc>

response, described in 8.4.3/T.32 (http://www.itu.int/rec/T-REC-T/e). A value of 0

disables either subparameter for using in copy quality checking.

8.39 +FIT: Inactivity timeout

A service Class 2 facsimile DCE shall provide an inactivity timer that allows the DCE to

break away from an unsuccessful connection attempt at any stage of a facsimile

transfer. The inactivity timer only works while the DCE is off-hook.

The <time> parameter indicates the inactivity timeout in seconds. The required

timeout is from 1 to 255 seconds. The value of 0 indicates that timeout is disabled. The

-Phase C data – T.4 or T.6 encoded data, or any other type of data (e.g. T.434 BFT),

transferred during execution of +FDT or +FDR commands.

-Phase B/D data – T.30 Phase B and Phase D control messages that are reported to

the DTE in +FHT: and +FHR: reports only (8.6) as well as enabled by the +FBU parameter

(8.5.1.10/T.32).

8.43 +FFC: Image data format conversion

This compound parameter determines “the DCE response to mismatches” between

the Phase C data delivered after the +FDT command and the data format

parameters negotiated for the facsimile session. [See +FCS: response (8.4.2.1/T.32)

and +FCS parameter (8.5.1.3/T.32).]

For mismatch checking, the DCE depends on the DTE to indicate the data format

with embedded <DLE><format> character pairs. If these format indicators are not

provided, the DCE shall assume that the format is as negotiated for that session.

For each subparameter, value 0 determines that mismatch checking is disabled, and

all format codes of this type are ignored. Value 1 determines that mismatch checking

is enabled, with session termination if the format codes do not match the negotiated

format reported in +FCS: responses. Other values enable degrees of format

conversion. Unspecified values are reserved.

9 GPRS Related Commands

9.1 +CGDCONT: Define PDP context

The set command specifies PDP context parameter values for a PDP context

identified by the (local) context identification parameter, <cid>. The number of PDP

contexts that may be in a defined state at the same time is given by the range

returned by the test command.

A special form of the set command, +CGDCONT= <cid> causes the values for

context number <cid> to become undefined.

The read command returns the current settings for each defined context.

The test command returns values supported as a compound value. If the MT supports

several PDP types, <PDP_type>, the parameter value ranges for each <PDP_type>

are returned on a separate line.

The set command specifies a profile for the context identified by the (local) context

identification parameter, <cid>. Since this is the same parameter that is used in the

+CGDCONT and +CGDSCONT commands, the +CGQREQ command is effectively an

extension to these commands. The QoS profile consists of a number of parameters,

9.3 +CGQMIN: Quality of Service profile (minimum acceptable)

This command allows the TE to specify a minimum acceptable profile which is

checked by the MT against the negotiated profile returned in the Activate PDP

Context Accept message.

The set command specifies a profile for the context identified by the (local) context

identification parameter, <cid>. Since this is the same parameter that is used in the

+CGDCONT and +CGDSCONT commands, the +CGQMIN 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.

9.4 +CGATT: GPRS attach or detach

The execution command is used to attach the MT to, or detach the MT from, the

Packet Domain service. After the command has completed, the MT remains in

V.25ter command state. If the MT is already in the requested state, the command is

ignored and the OK response is returned. If the requested state cannot be achieved,

an ERROR or +CME ERROR response is returned. Extended error responses are

enabled by the +CMEE command.

Any active PDP contexts will be automatically deactivated when the attachment

state changes to detached.

The read command returns the current Packet Domain service state.

The test command is used for requesting information on the supported Packet

Domain service states.

9.5 +CGACT: PDP context activate or deactivate

The execution command is used to activate or deactivate the specified PDP context

(s). After the command has completed, the MT remains in V.25ter command state. If

any PDP context is already in the requested state, the state for that context remains

unchanged. If the requested state for any specified context cannot be achieved, an

ERROR or +CME ERROR response is returned. Extended error responses are enabled by

the +CMEE command. If the MT is not PS attached when the activation form of the

command is executed, the MT first performs a PS attach and then attempts to

activate the specified contexts. Once the attach fails, the MT responds with ERROR or

with an appropriate failure-to-attach error message if extended error responses are

enabled.

If no <cid>s are specified the activation form of the command activates all defined

contexts.

If no <cid>s are specified the deactivation form of the command deactivates all

active contexts.

An active secondary context can exist if and only if the corresponding active primary

context exists. If the primary PDP context associated with a PDP address is

deactivated, all the associated secondary contexts are also deactivated and the

data transfer for that PDP address is disabled.

The read command returns the current activation states for all the defined PDP

contexts.

9.6 +CGDATA: Enter data state

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 GPRS

PDP types. This may include performing a GPRS attach and one or more PDP context

activations.

If the <cid> value is not defined to the MT, the MT will return an ERROR or +CME ERROR

response. Otherwise, the MT issues the intermediate result code CONNECT and enters

V.25ter online data state.

GPRS attachment and PDP 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 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.

M7-21-0010-121 - 247 - Version: 1.2.1 – 2010/12/30


If no <cid> is provided 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 completed, 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.

9.8 +CGAUTO: Automatic response to a network request for PDP context

activation

The set command disables or enables an automatic positive response (auto-answer)

to the receipt of a Request PDP Context Activation message from the network. It also

provides control over the use of the V.25ter basic commands 'S0', 'A and 'H' for

handling network requests for PDP context activation. The setting does not affect the

issuing of the unsolicited result code RING or +CRING.

The test command returns the values of <n> supported by the MT as a compound

value.

When the +CGAUTO=0 command is received, the MT shall not perform a PS detach if

it is attached. Subsequently, when the MT announces a network request for PDP

context activation by issuing the unsolicited result code RING or +CRING, the TE may

manually accept or reject the request by issuing the +CGANS command or may

simply ignore the network request.

When the +CGAUTO=1 command is received, the MT shall attempt to perform a PS

attach if it is not already attached. Failure will result in ERROR or, if enabled, +CME

ERROR being returned to the TE. Subsequently, when the MT announces a network

request for PDP context activation by issuing the unsolicited result code RING or

+CRING to the TE, this is followed by the intermediate result code CONNECT. The MT

then enters V.25ter online data state and follows the same procedure as it would

after having received a +CGANS=1 with no <L2P> or <cid> values specified.

For <n> = 1 Packet Domain network requests are automatically accepted according to the description above. For <n> = 2, automatic acceptance of Packet Domain network requests is controlled by the 'S0' command. Manual control uses the 'A' and 'H' commands, respectively, to accept and reject Packet Domain requests. (+CGANS may also be used.) Incoming circuit switched calls can be neither manually nor automatically answered. For <n> = 3, automatic acceptance of both Packet Domain network requests and incoming circuit switched calls is controlled by the 'S0' command. Manual control uses the 'A' and 'H' commands, respectively, to accept and reject Packet Domain requests. (+CGANS may also be used.) Circuit switched calls are handled as described elsewhere in this specification.

9.9 +CGANS: Manual response to a network request for PDP context

activation

The execution command requests the MT to respond to a network request for Packet

Domain PDP context activation which has been signaled to the TE by the RING or

+CRING: unsolicited result code. The <response> parameter allows the TE to accept

or reject the request.

If <response> is 0, the request is rejected and the MT returns OK to the TE.

If <response> is 1, the following procedure is followed by the MT.

Commands follows the +CGANS command in the AT command line shall not be

processed by the MT.

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.

The detailed behavior 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 more detail is provided

in 3GPP TS 29.061[39] and the specifications for the relevant PDPs. PDP context

activation procedures shall take place prior to or during the PDP startup.

One or more <cid>s may be specified in order to provide the values needed for the

context activation request.

During the PDP startup procedure the MT has the PDP type and the PDP address

provided by the network in the Request PDP Context Activation message. The MT

may also have some or all of the following information -

The MT may have a priori knowledge, for example, it may implement only one PDP

type.

Maybe the command has provided an <L2P> parameter value already.

The TE may provide one or both of PDP type and PDP address to the MT in the PDP

startup.

If any of this information is in conflict, the command will fail.

If one or more <cid> is provided, an attempt shall be made to identify an appropriate

context definition by matching the PDP type and PDP address in the network request

M7-21-0010-121 - 253 - Version: 1.2.1 – 2010/12/30


with the PDP type and PDP address in each of the specified context definitions (in the

order in which their <cid>s appear in the command) as follows -

The PDP type must match exactly.

The PDP addresses are considered for matching if they are identical or if the address

in the context definition is unspecified.

The context shall be activated using the values for PDP type and PDP address

provided by the network, together with the other information found in the PDP

context definition. An APN may or may not be required, depending on the

application.

If no <cid> is provided or if there is no matching context definition, the MT will attempt

to activate the context using the values for PDP type and PDP address provided by

the network, together with any other relevant information known to the MT. The other

context parameters will be set to their default values.

If the activation is successful, data transfer may proceed.

After data transfer is completed, 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 startup, 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. It is also an error to

issue the +CGANS command when there is no outstanding network request.

NOTE: This is not the same as if the MT issues a +CGDATA (or +CGACT) command

after receiving a +CRING unsolicited result code. A +CGDATA (or +CGACT) does not

command the MT to acknowledge the network request but rather to make a new

request for context activation. The network request would be ignored.

The test command returns the values of <response> and <L2P> supported by the MT

as compound values.

This command may be used in both normal and modem compatibility modes.

9.14 D: Request GPRS service

This command causes the MT to perform any action that is necessary to establish

communication between the TE and external PDN.

The V.25ter’D’(Dial) command causes the MT to enter the V.25ter online data state

and, with the TE, to start the specified layer2 protocol. The MT shall return CONNECT to

confirm acceptance of the command prior to enter the V.25ter online data state. No

further commands may follow on the AT command line.

The detailed behavior after the online data state has been entered is dependent on

the PDP type. It is described briefly in clauses 8 (for X.25) and 9 (for IP) of GSM 07.06.

GPRS attachment and PDP 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.

When the layer 2 protocol has terminated, either as a result of sequentially shut down

of the PDP or an error, the MT shall enter V.25ter command state and return the NO

CARRIER final result code.

If <called_address> is supported and provided, the MT shall automatically set up a

virtual call to the specified address after the PDP context has been activated.

If <L2P> and <cid> are supported, their usage shall be the same as in the +CGDATA

command. Commands such as +CGDCONT, +CGQREQ, etc. may then be used in

the modem initialization AT command string to set values for PDP type, APN, QoS etc.

If <L2P> is not supported or is supported but omitted, the MT shall use a layer 2

protocol appropriate to the PDP type.

If <cid> is not supported or is supported but omitted, the MT shall attempt to activate

the context using:

any information provided by the TE during the PDP startup procedure, e.g. the TE may

provide a PDP type and/or PDP address to the MT,

or (b) a prior knowledge, e.g. the MT may implement only one PDP type,

or (c) using the ‘Empty PDP type’ (GSM 04.08). (No PDP address or APN shall be sent in

this case and only one PDP context subscription record shall be present in the HLR for

this subscriber.)

This command may be used in both normal and modem compatibility modes.

9.15 S0: Automatic response to a network request for PDP context activation

The V.25ter ‘S0=n’ (Automatic answer) command may be used to turn off (n=0) and

on (n>0) the automatic response to a network request for a PDP context activation.

When the ‘S0=n’ (n>0) command is received, the MT shall attempt to perform a GPRS

attach if it is not already attached. Failure will result in ERROR being returned to the TE.

Subsequently, the MT will announce that a network request for PDP context activation

by issuing the URC RING or CRING to the TE, follow by the intermediate result code

CONNECT. The MT then enters V.25ter online data state and follows the same

procedure as it would after having received a +CGANS=1 with no <L2P> or <cid>

values specified.

Set command disables or enables the use of result code +CME ERROR: <err> as an

indication of an error relating to the functionality of the ME. When enable, ME related

errors cause +CME ERROR: <err> final result code instead of the regular ERROR final

result code. ERROR is returned normally when error is related to syntax, invalid

parameters, or TA functionality.

12.2 +CME ERROR: ME error result code

The operation of +CME ERROR:<err> result code is similar to the regular ERROR result

code: if +CME ERROR:<err> is the result code for any of the commands in a command

line, none of the following commands in the same command line is executed.

(neither ERROR nor OK result code shall be returned as a result of a completed

command line execution). The format of <err> can be either numeric or verbose. This
