Defined Values
<SC
1
>: Service Code is a digit string which identifies a request to use
value 17 Voice Group Call Service
value 18 Voice Broadcast Service
<SC
2
>: Service Code is a digit string which identifies a request to use eMLPP priority . Service Code values for
different priority levels are specified in 3GPP TS 22.030 [19]
<GId>: a digit string that specifies the group identification of a called party.
Implementation
Mandatory for a MT supporting AT commands only and VGCS or VBS is implemented.
11.2.2 Termination of an Voice Group or Voice Broadcast Call 'H'
The V.250 'H' or 'H0' (On-hook) command may be used to terminate an ongoing voice group or voice broadcast call.
The MT responds with OK. It is an error to issue the 'H' command when there is no outstanding network request.
It is an error to issue the 'H' command if the user is in group receive mode or the user is not the originator of the call and
a ERROR or +CME ERROR result code is returned to the TE.
NOTE: This is an extension to the usage of the 'H' command that is described in ITU-T V.250.
Implementation
Mandatory for a MT supporting AT commands only and VGCS or VBS is implemented.

Description
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 EF
VGCSS
on the SIM. The read command returns
all subscribed GIds in EF
VGCS
and their status in EF
VGCSS
from the SIM.
Defined values
<GId> integer type, group Id as specified in 3GPP TS 22.030 [19]
<status>: integer type, value
0 deactivated
1 activated
Implementation
Mandatory for a MT supporting AT commands only and supporting VGCS.
