User Control Services
Item Description
Class-of-Service The MSC/HLR allows users to be grouped based on the
Class-of-Service (COS) groups. Network Class-of-
Service (NCOS) allows additional differentiation within
each customer group. There are a maximum of 256
NCOS per subscriber group that can define the
originating and terminating restrictions on a MS. The
combination of COS and NCOS allows the service
provider to manage the type of customer services such as
barring of 900 calls and abbreviated dialing.
Closed User Group This feature allows service providers to customize calling
privileges among user groups. If a business owner desires
to restrict telephone usage the providers can customize
calling privileges by:
• Call Origination/Termination
• to/from the PSTN
• to/from other CUG members
• to/from the PSTN / PLMN
Call Restrictions The most common call restrictions requested by service
provider are Barring Incoming Calls, Barring Outgoing
Calls, Barring Of Outgoing International Calls, Local
Calls Only and Class Of Service.
Incoming Calls Only Barring All Outgoing Calls (BAOC) denies outgoing
calls by subscriber. Emergency calls (911) are not barred.
Local Calls Only A user may be restricted to calls within a defined local
area using allowed and or denied NXXs tables. This
feature does not interact with Call Forwarding.

Source Directed Routing Source Directed Routing will direct mobile originated
calls from one or more cells to predetermined
destinations based on Translation Table in the MSC.

Routing
Time of Day (TOD) Routing enables or disables trunks,
trunk groups, and trunk routes based on a time of day
scheduling. Schedules may be day of week, day of year,
weekends and statuary holiday requirements.

be defined for any day, or set of days on a weekly basis,
or for any specific day of the year.
Connecting Comfort Tone
and Call Forwarding
Announcement
A comfort tone is sent to the calling party while the MS
is being paged. The tone is a recorded announcement.
Typically a pip tone is used.
Comfort Tone on Hold Comfort Tone on Hold allows service providers to record
a custom announcement that is sent when the calling
party is on hold. When an MS places a call on hold, the
announcement is played, reassuring the calling party that
their call is still in process.
