4 Anonymous Communication Rejection (ACR) and
Communication Barring (CB)
4.1 Introduction
The Communication Barring (CB) service offers the following services:
- The Incoming Communication Barring (ICB) is a service that rejects incoming communications that fulfil
certain provisioned or configured conditions on behalf of the terminating user.
- The Anonymous Communication Rejection (ACR) is a particular case of the ICB service, that allows barring of
incoming communications from an anonymous originator on behalf of the terminating user.
- The Outgoing Communication Barring (OCB) is a service that rejects outgoing communications that fulfil
certain provisioned or configured conditions on behalf of the originating user.
4.2 Description
4.2.1 General description
The Incoming Communication Barring (ICB) service makes it possible for a user to have barring of certain categories
of incoming communications according to a provisioned or user configured barring program and is valid for all
incoming communications. A barring program is expressed as a set of rules in which the rules have a conditional part
and an action part. Examples of conditions are whether the asserted originating public user identity matches a specific
public user identity or whether the originating public user identity is restricted (anonymous). The action part could
specify for a rule that contains a matching condition that the specific incoming communication is barred. The complete
set of conditions and actions that apply to this service and their semantics is described in clause 4.9.
The Inhibition of Incoming Forwarded Calls is a special case of the ICB and allows the served user to reject incoming
communications from users or subscribers who have diverted the communication towards the served user. The
communication history information will be used to trigger the service as described in clause 4.9.
The Anonymous Communication Rejection (ACR) service allows the served user to reject incoming communications
on which the asserted public user identity of the originating user is restricted. In case the asserted public user identity of
the originating user is not provided then the communication is allowed by the ACR service.
An example where the originating user restricts presentation of the asserted public user identity is when he activated the
OIR service 3GPP TS 24.607 [3].
The originating user is given an appropriate indication that the communication has been rejected due to the application
of the ACR service.
The Anonymous Communication Rejection (ACR) service is a special case of the ICB service, which is highlighted
here because it is a regulatory service in many countries. The ACR service can be activated for a specific subscriber by
configuring an ICB service barring rule where the conditional part contains the "Condition=anonymous" and the action
part "allow=false".
The Outgoing Communication Barring (OCB) service makes it possible for a user to have barring of certain categories
of outgoing communications according to a provisioned or user configured barring program and is valid for all outgoing
communications. A barring program is expressed as a set of rules in which the rules have a conditional part and an
action part. An example condition is whether the request uri matches a specific public user identity. The action part can
specify for a rule that contains a matching condition that the specific outgoing communication it to be barred. The
complete set of conditions and actions that apply to this service and their semantics is described in clause 4.9.
