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
WCDMA Module
6
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.
WCDMA Module
14
+CSTA=[<type>]
+CSTA?
Command
+CSTA=?
Defined values
<type>: type of address octet in integer format (refer TS 24.008 [8] subclause
10.5.4.7); default 145 when dialling
string includes international access code character "+", otherwise 129
3.3 +CMOD Call mode
Description
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?
Command
+CMOD=? +CMOD: (list of supported <mode>s)
Defined values
<mode>:
0 single mode
1 alternating voice/fax (teleservice 61)

3.17 +ZFLSH Send Flash/Flash with Information
Descriptions
The command is used to send a Flash/Flash with information to the base station,
and it is usually used for call waiting and conference call. When receiving a call from a
third party, use AT+ZFLSH command to send FLASH signals to switch between two
differenct lines. If one FLASH signal is sent to the base station, the module will return
with +ZFLSH. Please note that this doesn’t guarantee the switching between two lines
for CDMA network because the network does not return the confirmation to the
module. In a conference call, define the first called party as the first party, dial the first
party, use AT+ZFLSH=< second called party’s number to call the second party, and
the first party would automatically enter the call held status; once the second call is
connected, use AT+ZFLSH command to realize the conference call. If you send a
FLASH signal again, it will disconnect the call from the second party. Use ATH
command to hang up all calls.

4.3 +COPS PLMN selection
Description
Set command forces an attempt to select and register the GSM/UMTS network
operator. <mode> is used to select
whether the selection is done automatically by the MT or is forced by this
command to operator <oper> (it shall be
given in format <format>) to a certain access technology, indicated in <AcT>. If
the selected operator is not
available, no other operator shall be selected (except <mode>=4). If the
selected access technology is not available,
then the same operator shall be selected in other access technology. The
selected operator name format shall apply to
further read commands (+COPS?) also. <mode>=2 forces an attempt to
deregister from the network. The selected
mode affects to all further network registration (e.g. after <mode>=2, MT shall
be unregistered until <mode>=0 or 1 is
selected). Refer subclause 9.2 for possible <err> values. This command should
be abortable when
registration/deregistration attempt is made.
Read command returns the current mode, the currently selected operator and
the current Access Technology. If no
operator is selected, <format>, <oper> and < AcT> are omitted.
Test command returns a set of five parameters, each representing an operator
present in the network. A set consists of
an integer indicating the availability of the operator <stat>, long and short
alphanumeric format of the name of the
operator, numeric format representation of the operator and access technology.
Any of the formats may be unavailable
and should then be an empty field. The list of operators shall be in order: home
network, networks referenced in SIM or
active application in the UICC (GSM or USIM) in the following order: HPLMN

Description
By using this command instead of Generic SIM Access +CSIM TE application
has easier but more limited access to the
SIM database. Set command transmits to the MT the SIM <command> and its
required parameters. MT handles
internally all SIM-MT interface locking and file selection routines. As response to
the command, MT sends the actual
SIM information parameters and response data. MT error result code +CME
ERROR may be returned when the
command cannot be passed to the SIM, but failure in the execution of the
command in the SIM is reported in <sw1>
and <sw2> parameters. Refer to subclause 9.2 for <err> values.
Coordination of command requests to SIM and the ones issued by GSM/UMTS
application inside the MT is
implementation dependent. However the TE should be aware of the precedence
of the GSM/UMTS application
commands to the TE commands.
