20.15 Closed User Group +CCUG
20.15.1 Description
This command is used to:
• activate/deactivate the control of CUG information for all following outgoing
calls,
• select a CUG index,
• suppress Outgoing Access (OA). OA allows or not a member of a CUG to place
calls outside the CUG.
• suppress the preferential CUG. Preferential is the default CUG used by the
network when it does not receive an explicit CUG index.
The Closed User Group Supplementary Service enables subscribers to form groups
with restricted access (both access to and from).
The CUG supplementary service is described in GSM 02.85 [25]. This service is
provided on prior arrangement with the service provider. Subscription options should
be selected at implementation.
