4 Applicability to Supplementary Services (SS)

22.0413GPPOperator Determined Barring (ODB)TS

Operator Determined Barring is a network feature and hence applies to Supplementary Service aspects of subscriptions.

Operator Determined Barring is applied independently from Supplementary Services. Nevertheless the following interactions occur:

Call Barring:

Calls will be denied if either Operator Determined Barring or Subscriber Controlled Barring determine that the call should be barred.

If a call is barred due to both Operator Determined Barring and Subscriber Controlled Barring, then the message or notification returned towards the caller will be the same as if the barring was due solely to Operator Determined Barring (see Section 5).

There is no other interaction.

Call Forwarding:

If a call forwarding programme is in contravention of an Operator Determined Barring Category, when the latter is activated, then the activation shall result in making call forwarding quiescent. If the subscriber attempts to activate a new call forwarding programme in contravention of an Operator Determined Barring Category, then the activation shall be denied, and the subscriber informed of the denial. There is no other interaction.

Closed User Group:

CUG restrictions must be met in addition to Operator Determined Barring restrictions for a call to proceed.

If a call is barred due to both Operator Determined Barring and CUG restrictions, then the message or notification returned towards the caller will be the same as if the barring was due solely to Operator Determined Barring (see Section 5).

There is no other interaction.

Call Transfer:

If the subscriber attempts to invoke a call transfer in contravention of an Operator Determined Barring category, then the invocation shall be denied, and the subscriber informed of the denial. There is no other interaction.

Multi-Party, Advice of Charge, CLIP, CLIR, COLP, COLR, Call Wait, Call Hold:

There is no interaction.

Call Completion to Busy Subscriber, User to User Signalling, Malicious Call Identification, Mobile Access Hunting:

For further study.

The application of a Barring of Roaming category (see subclauses 3.1 and 3.2 below) will, if the Mobile Station is roaming appropriately, prevent the Mobile Subscriber from undertaking any form of Supplementary Service management.
