4 Connected Line Identification Restriction (COLR)
22.0813GPPLine Identification supplementary servicesStage 1TS
4.1 Definition
The COLR Supplementary Service enables the connected party to prevent presentation of its line identity to the calling party.
4.2 Description
4.2.1 Description
The COLR Supplementary Service is a Supplementary Service offered to the connected party to prevent presentation of the connected line identity, to the calling party. In the case where the calling party has an override category, see subclause 4.4.
4.2.2 Applicability to telecommunications services
The applicability of this Supplementary Service is defined in 3GPP TS 22.004.
4.3 Normal procedures with successful outcome
4.3.1 Provision
This Supplementary Service is provisioned for all Basic Services subscribed to and to which it is applicable, i.e. not provisioned for any subset of these Basic Services.
4.3.2 Withdrawal
This Supplementary Service will be withdrawn at the subscriber’s request or for administrative reasons.
4.3.5 Activation
The COLR Supplementary Service shall be activated on provision.
4.3.6 Deactivation
The COLR Supplementary Service shall be deactivated on withdrawal.
4.3.7 Invocation
The network shall automatically invoke the COLR Supplementary Service for each incoming call at call set-up phase.
4.3.8 Normal operation with successful outcome
If the calling party subscribes to the COLP Supplementary Service and the COLR Supplementary Service has been invoked, then the calling party shall receive an indication that the connected line identity is not available due to restriction.
When the COLR Supplementary Service is invoked, the destination network shall provide the originating network with a notification that the line identity of the connected party is not allowed to be presented to the calling party.
4.3.11 Interrogation
Status check
The mobile subscriber can request the status of the Supplementary Service and be informed if the service is provided to her.
4.4 Exceptional procedures or unsuccessful outcome
If the calling party has a relevant override category (see subclause 3.3.1) the restriction service will be overridden and the connected line identity will be presented to the calling party.
4.5 Alternate procedures
A VPLMN which supports the COLR service shall ensure that the line identity of a subscriber whose HPLMN does not support the COLR service shall not be displayed to the calling party unless the calling party has COLR override capability.
4.6 Interactions with other Supplementary Services
4.6.81.3 Connected line identification presentation
See subclause 3.6.81.4.
4.6.82.1 Call forwarding unconditional
If a forwarded-to user subscribes to the COLR Supplementary Service, then the forwarded-to user’s line identity shall not be provided with the notification that the call has been forwarded.
A calling user that subscribes to the COLP Supplementary Service and who has override capability shall not be able to receive the forwarded-to user’s line identity as part of the diverting notification information, but can invoke the COLP Supplementary Service with override in order to receive the connected line identity when the call is answered.
4.6.82.2 Call forwarding on mobile subscriber busy
Same as the interaction with call forwarding unconditional.
4.6.82.3 Call forwarding on no reply
Same as the interaction with call forwarding unconditional.
4.6.82.4 Call forwarding on mobile subscriber not reachable
Same as the interaction with call forwarding unconditional.
4.7 Interworking consideration
On calls from or via non-ISDNs, it cannot be assured that a connected line restriction indication can be carried to the originating network. As a national option, the destination network can restrict any information identifying the connected party from being returned to the originating network when the COLR Supplementary Service is applicable. If an originating network receives a connected line identity without any indication of presentation allowed or restricted, the originating network shall act according to its rules and regulations.
For inter-network calls, when the COLR Supplementary Service is invoked, the destination network shall provide the originating network with a notification that the line identity of the connected party is not allowed to be presented to the calling party.
NOTE: When the COLR Supplementary Service is invoked, some network providers may not send the identity of the connected customer to other network providers.
