The execute command accepts an incoming or ongoing voice group or voice broadcast call. Refer to clause 9.2 for possible <err> values. See command +CALCC to get a list of current voice group or voice broadcast calls.

The execute command rejects an incoming voice group or voice broadcast call indicated by RING or +CRING, the command is applicable as long as the indication is pending. Refer to clause 9.2 for possible <err> values. If the call is once rejected the RING or +CRING indication is not repeated to TE although the call is still running and notifications for the call are received. See command +CALCC to get a list of current voice group or voice broadcast calls.

<GId> <GCA> <service>

The execute command forces the MT to leave the active voice group or voice broadcast call without terminating it. The command is only applicable if the MT is in group receive mode. The MT returns to idle mode. Refer to clause 9.2 for possible <err> values.

The execute command emulates the Push To Talk function for VGCS talker access. If the parameter <mode> is set to value "0" i.e. "RELEASED" the PTT key is assumed to be released immediately. If the parameter <mode> is set to value "1" i.e. "PUSHED" the PTT key is assumed to be pushed immediately for the period of <time> in seconds. If the command execution is repeated before the <time> expires the PTT timer will be loaded with the new <time> value and the PTT key remains "PUSHED" for the period of new <time> in seconds. If the parameter <mode> is set to value "2" i.e. "PUSHED" the PTT key is assumed to be pushed immediately for an infinite period of time and can be released by <mode> value 0. For <mode>=0 if the parameter <time> is issued it is ignored. If the PTT timer expires after <time> seconds during <mode> "PUSHED" an unsolicited result code +CAPTT: 0 is issued to the TE. Refer to clause 9.2 for possible <err> values. The read command returns the current <mode>. The test command returns values supported as compound values.

<mode> <time>

The set command enables or disables the presentation of uplink access status for an active VGCS call. When enabled the unsolicited result code +CAULEV: <status> is returned from MT to TE whenever the call uplink status changes. Refer to clause 9.2 for possible <err> values. Read command returns the current uplink <status> and the selected <mode>. The test command returns values supported as a compound value.

<mode> <status>

Mandatory for a MT supporting AT commands only and VGCS is implemented.

The set command returns for <mode>=1 the active voice group or voice broadcast call and for <mode>=0 a list of all current running voice group and voice broadcast calls for which the user has a subscription and the GId is activated on the SIM. If the command succeeds but no calls are available, OK response is returned. Refer to clause 9.2 for possible <err> values. Test command returns the values supported as a compound value.

<mode> <GId> <GCA> <service> <stat> <dir> <ack_flag> <priority>

Optional. Recommended for an MT supporting AT commands only and VGCS or VBS is implemented.

The set command enables or disables the presentation of unsolicited result code +CACSP: <da>,<ua>,<comm>,<oi> from MT to TE if the call control state attributes of the active voice group or voice broadcast call changes. Read command returns the current call control state attributes <da>, <ua>, <comm>, <oi> and selected <mode>. Refer to clause 9.2 for possible <err> values. The test command returns values supported as a compound value.

<mode> <da> <ua> <comm> <oi>

Optional. Recommended for a MT supporting AT commands only and VGCS or VBS is implemented.

The set command enables or disables the presentation of unsolicited result code +CANCHEV: <status> from MT to TE if the status of the network NCH support information changes. Read command returns in parameter <status> the network NCH support information in the selected cell and the selected <mode>. Refer to clause 9.2 for possible <err> values. The test command returns values supported as a compound value.

<mode> <status>

Optional. Recommended for a MT supporting AT commands only and VGCS or VBS is implemented.

This command allows control of the Originator-to-Dispatcher Information and Compressed Originator-to-Dispatcher Information according to TS 44.068 and TS 44.069. When <message> and <OTDIE> are both present the string specified in <OTDIE> is included in the corresponding group or broadcast control <message> as the value part of the Originator-to-Dispatcher Information Element or Compressed Originator-to-Dispatcher Information Element (as defined in TS 44.068 and TS 44.069) into all subsequent messages of type <message>. If parameter <message> is present but parameter <OTDIE> is not present then the Originator-to-Dispatcher Information Element shall not be present in sub-sequent messages of type <message>. Refer to clause 9.2 for possible <err> values. The read command returns the content of <message> and of <OTDIE>. If no <OTDIE> is available, no information text shall be returned. Test command returns values supported as a compound value.

<message> <OTDIE>

Optional.

The execute command emulates the Short Data Transmission during ongoing VGCS according to TS 42.068 and TS 43.068. The application indicator <mode> is used to identify whether the application data is an application-specific data or is a confirmation. The data identifier <dataid> is to provide a sequence number of the sending of application data. The value of the data identifier <dataid> is dependent on the value of the application indicator <mode>. If the application indicator <mode> indicates sending application data to the network, the data identifier <dataid> contains a number from the range between 0 and 15 which is generated by the mobile station. If the application indicator <mode> indicates sending confirmation of the reception of the application data, the data identifier <dataid> shall contain the data identifier which was received in the data identity sent by the previous sender. The distribution parameter <dist-param> contains information to which participants shall be transferred the short data. The response CEPTT string from the network to the other participants is returned in a subsequent unsolicited result code +CEPTT: <mode>,<data>,<dataid>,<dist-param>[,<number>]. Refer to clause 9.2 for possible <err> values. Test command returns values supported as compound values.

<mode> <data> <dataid> <dist-param> <mode>

Execution command returns the MT Group Id prefix management capability, according to TS 43.068. Refer to clause 9.2 for possible <err> values.

<status>

Optional.

This Dial command extension is a service request application according to TS 22.030. No further commands may follow on the AT command line. Responses When the call has terminated, either as a result of an orderly termination or an error, the MT shall return the NO CARRIER final result code. Possible error responses include +CME ERROR: <err> when error is related to MT functionality. The requested service, GId and priority level are checked against the subscriptions of the user and the status of the GId stored on the SIM. In case if no subscription is available for this service, GId or priority level or the GId is deactivated an ERROR or +CME ERROR result code is returned. The requested Group Id prefix is not checked against susbscription. The Group Id prefixes are not stored in the SIM/USIM card. If Service Code for Group Id prefix is used, but is not managed by MT, an ERROR or +CME ERROR result code is returned. See +CME ERROR extensions for VGCS, VBS and eMLPP in clause 9.2.3. Detailed error report of an unsuccessful originated call can be obtained with command Extended Error Report +CEER (if implemented).

This command works with SIM Card and when the GSM Application is selected in UICC. Function with USIM is for further study. The set command is used to edit the status of the GId EFVGCSS on the SIM. The read command returns all subscribed GIds in EFVGCS and their status in EFVGCSS from the SIM. Refer to clause 9.2 for possible <err> values. The test command returns the values supported by the UE as compound values.
