0 Scope
The present document describes the Supplementary Services belonging to the group Line Identification Supplementary
Services.
The general aspects, including definitions and recommended provision, of the description of the Supplementary
Services are given in 3GPP TS 22.004.
The group of Line Identification Supplementary Services is divided into the following four Supplementary Services:
CLIP - Calling line identification presentation (clause 1);
CLIR - Calling line identification restriction (clause 2);
COLP - Connected line identification presentation (clause 3);
COLR - Connected line identification restriction (clause 4).
Definition of line identity: The line identity is made up of a number of information units:
- the subscriber's national ISDN/MSISDN number (MSISDN number is the number stored in the VLR);
- the country code;
- optionally, subaddress information. The PLMN cannot be responsible for the content of this subaddress. (For
definition of the subaddress see ITU-T Recommendation E.164 [3] subclause 11.2).
In a full ISDN environment, the line identity shall include all the address information necessary to
unambiguously identify a subscriber.
The calling line identity is the line identity of the calling party.
The connected line identity is the line identity of the connected party.
If for the line identity of the calling party or the connected party additional line identification is received (additional
calling party/connected party number) in a PLMN this additional line identification shall be used for the presentation
purpose of the line identification presentation services.
Definition of Presentation and Screening Indicators: In addition to or instead of the line identity, the network may
give a Presentation Indicator (PI) and/or a Screening Indicator (SI) to the served subscriber. The following information
may be given:
- Presentation Indicator showing:
a) presentation allowed, or
b) presentation restricted, or
c) number not available due to interworking;
If Presentation Indicator is set to "Presentation Restricted", then the MS can get additional information on the Cause of
no CLI, if provided by the network.
The Cause of no CLI value may be one of the following :
- Unavailable
- reject by user
- interaction with other services
- coin line / pay phone
- Screening Indicator showing:
a) user provided, verified and passed, or

b) user provided, not screened, or
c) network provided.
If the line identity is that of a PLMN subscriber, then:
the national number and the country code shall always be provided by the network;
the subaddress shall only be included if it is provided by the user (or user equipment);
the screening indicator shall indicate "network provided".

1 Calling Line Identification Presentation (CLIP)
1.1 Definition
The CLIP Supplementary Service provides the called party with the possibility to receive the line identity of the calling
party.
1.2 Description
1.2.1 Description
This Supplementary Service provides for the ability to indicate the line identity of the calling party to the called party.
The network shall deliver the calling line identity to the called party at call set-up time, regardless of the terminal
capability to handle the information.
1.2.2 Applicability to telecommunication services
The applicability of this Supplementary Service is defined in 3GPP TS 22.004 [2].

1.3 Normal procedures with successful outcome
1.3.1 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.
Override category within a PLMN
Override category within an ISDN/PLMN. Depending on national regulations, some networks may define
categories of subscribers that have the ability to override the presentation restriction (CLIR, clause 2) and have
the calling line identity presented (e.g., the police). The ability to have such override category is a national
option.
Override category between a PLMN and a network providing calling line identification restriction
Override category between ISDN/PLMNs. When a call originates in one ISDN/PLMN and terminates in another
ISDN/PLMN and the CLIR Supplementary Service is applied, the rules and regulations of the destination
network shall apply. For example, the override category may not be applicable in the originating network but
may be applicable in the destination network. In this situation, a call with the CLIR Supplementary Service
applied can still be overridden in the destination network.
The override category is only applicable within the HPLMN country.
1.3.2 Withdrawal
The CLIP Supplementary Service shall be withdrawn at the customer's request or for administrative reasons.
1.3.5 Activation
The CLIP Supplementary Service is activated as a result of provision.
1.3.6 Deactivation
The CLIP Supplementary Service is deactivated as a result of withdrawal.
1.3.7 Invocation
The network shall automatically invoke the CLIP Supplementary Service in the call set-up phase.
1.3.8 Normal operation with successful outcome
A user who has subscribed to the CLIP Supplementary Service and receives a call shall also receive the line identity of
the calling party.
Note: The decision of whether the user-defined name stored in the handset should take precedence over the line
identity of the calling party is a handset implementation issue. However for user experience it may be
preferable to display the user-defined name available. In case there are several names associated with the
number it is up to the handset implementation to choose which name to display.
In addition to or instead of the calling line identity, the subscriber may be given a Presentation Indicator and/or a
Screening Indicator with the relevant information. If provided by the network, the subscriber may also be given some
additional information on the Cause of no CLI in case of a presentation restricted.
1.3.11 Interrogation
Status check
The mobile subscriber can request the status of the Supplementary Service and be informed if the service is provided to
her.
