1 Definitions and abbreviations
1.1 Command line
See figure 2 for general structure of a command line. Standardized basic commands are found only in
V.250 [14].
GSM/UMTS commands use syntax rules of extended commands. Every extended command has a
test command
(trailing =?) to test the existence of the command and to give information about the type of its
subparameters.
Parameter type commands also have a read command (trailing ?) to check the current values of
subparameters. Action
type commands do not store the values of any of their possible subparameters, and therefore do not
have a read
command.
If verbose responses are enabled with command V1 and all commands in a command line has been
performed
successfully, result code <CR><LF>OK<CR><LF> is sent from the TA to the TE. If numeric
responses are enabled
with command V0, result code 0<CR> is sent instead.
If verbose responses are enabled with command V1 and subparameter values of a command are not
accepted by the TA
(or command itself is invalid, or command cannot be performed for some reason), result code
<CR><LF>ERROR<CR><LF> is sent to the TE and no subsequent commands in the command line
are processed. If
numeric responses are enabled with command V0, result code 4<CR> is sent instead. ERROR (or 4)
response may be
replaced by +CME ERROR: <err> (refer clause 9) when command was not processed due to an error
related to MT
operation.
1.2 Information responses and result codes
The TA response for the example command line of figure 2 could be as shown in figure 3. Here,
verbose response
format is enabled with command V1. If numeric format V0 would have been used, <CR><LF> headers
5
WCDMA Module
of information
responses would have been left out and final result code changed to 0<CR>.
So called intermediate result codes inform about progress of TA operation (e.g. connection
establishment CONNECT),
and so called unsolicited result codes indicate occurrence of an event not directly associated with
issuance of a
command from TE (e.g. ring indication RING).

3 Call control commands and methods
3.1 ATD\ATA\ATH\ATS0
V.250 [14] dial command D lists characters that may be used in a dialling string for making a call or
controlling
supplementary services in accordance with 3GPP TS 22.030 [19]. Their use in GSM/UMTS is listed in
this subclause,
as well as new dial modifiers applicable only to GSM/UMTS are introduced. For a MT supporting AT
commands only,
it is mandatory to support the control of supplementary services in accordance with 3GPP TS 22.030
[19] through the
dial command or through the specific supplementary service commands (+CCFC, +CLCK, etc.),
where 3GPP TS 22.030
[19] identifies the supplementary services as mandatory.
V.250 dialling digits
1 2 3 4 5 6 7 8 9 0 * # + A B C (implementation of these characters is mandatory for GSM/UMTS)
D (implementation of this character is optional for GSM/UMTS, and it is ignored)
V.250 modifier characters
, (implementation of this character is mandatory for GSM/UMTS, but it may be ignored)
T P (implementation of these characters is mandatory for GSM/UMTS, but they are ignored)
! W @ (implementation of these characters is optional for GSM/UMTS, and they are ignored)
V.250 semicolon character
In GSM/UMTS, when semicolon character is given after dialling digits (or modifiers), a voice call
originated to the
given address. TA returns to command state immediately (or after possible +COLP result code; refer
subclause
"Connected line identification presentation +COLP"). Refer Annex G for a detailed example.
GSM/UMTS modifier characters
> (refer subclause "Direct dialling from phonebooks")
I or i (override the CLIR supplementary service subscription default value for this call; I = invocation
(restrict CLI
presentation) and i = suppression (allow CLI presentation); refer subclause "Calling line identification
restriction
+CLIR")
G or g (control the CUG supplementary service information for this call; uses index and info values set
with command
+CCUG; refer subclause "Closed user group +CCUG")
3.2 +CSTA Select type of address
Description
Set command selects the type of number for further dialling commands (D)
according to GSM/UMTS specifications.
Test command returns values supported a compound value.

+CSTA=[<type>]
+CSTA?
+CSTA=?
10.5.4.7); default 145 when dialling
string includes international access code character "+", otherwise 129
3.3 +CMOD Call mode
Description
Command
Defined values <mode>:
Set command selects the call mode of further dialling commands (D) or for next
answering command (A). Mode can be
either single or alternating (in the present document, terms "alternating mode"
and "alternating call" refer to all
GSM/UMTS bearer and teleservices that incorporate more than one basic
service (voice, data, fax) within one call).
When single mode is selected the call originating and hangup procedures are
similar to procedures specified in ITU-T
Recommendations V.250 [14], T.31 [11] and T.32 [12]. In GSM/UMTS there can
be voice followed by data (refer
3GPP TS 22.002 [1]), alternating voice/data (refer 3GPP TS 22.002 [1]) and
alternating voice/fax calls (refer 3GPP TS
22.003 [2]). Refer next two subclauses for alternating call control methods.
+CMOD=[<mode>]
+CMOD?
+CMOD=? +CMOD: (list of supported <mode>s)

TS 22.067 [54].
<subaddr>: string type subaddress of format specified by <satype>
<satype>: type of subaddress octet in integer format (refer 3GPP TS 24.008 [8]
subclause 10.5.4.8)
<PDP_type> ,<PDP_addr> and <APN> are as defined in the Define PDP
Context (+CGDCONT) command. The
optional <L2P> proposes a layer 2 protocol to use between the MT and the TE.
It is defined in the Enter GPRS Data
Mode (+CGDATA) command. If the MT is unable to announce to the TE the
network's request (for example it is in
V.250 online data state) the MT shall reject the request. No corresponding
unsolicited result code shall be issued when
the MT returns to a command state.
<GCA> is a part of the group call reference as specified in 3GPP TS 23.003 [7]
and indicates group call area.
<GId> is a part of the group call reference as specified in 3GPP TS 23.003 [7]
and indicates group call
identification.The <ackflag>=1 proposes that a predefined confirmation
procedure is to be used after the call is ended.
For <ackflag>=0 no confirmation procedure is required.

Description
Command
This refers to the amplification by the TA of audio samples sent from the TA to
the computer. The command operates
on an integer <n>, range 0...255. Values larger than 128 indicate a larger gain
than nominal. Values less than 128
indicate a smaller gain than nominal. The entire range of 0...255 does not have
to be provided. A value of zero implies
the use of automatic gain control by the TA.

Description
Command
Defined values <n>:
This refers to an integer <n> that defines the length of tones emitted as a result
of the +VTS command. This does not
affect the D command. A value different than zero causes a tone of duration
<n>/10 seconds. The value zero causes a
"manufacturer specific" value.

Description
Defined values 1. <DTMF>. A single ASCII character in the set 0-9, #,*,A-D. This is interpreted
This command allows the transmission of DTMF tones and arbitrary tones (see
note). These tones may be used (for
example) when announcing the start of a recording period. The command is
write only. In this profile of commands,
this command does not operate in data or fax modes of operation
(+FCLASS=0,1,2-7).
+VTS=as above Command
+VTS=? (list
as a single ACSII character whose
duration is set by the +VTD command.
NOTE 2: In GSM this operates only in voice mode.
2. [<tone1>,<tone2>,<duration>]. This is interpreted as a dual tone of
frequencies <tone1> and <tone2>,
lasting for a time <duration> (in 10 ms multiples).
NOTE 3: This does not operate in GSM.
3. {<DTMF>,<duration>}. This is interpreted as a DTMF tone of different
duration from that mandated by the
+VTD command.
