34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification
15.1.1 CLIP / Normal operation
15.1.1.1 Definition
To test that the UE correctly presents to the user the calling number.
15.1.1.2 Conformance requirements
The calling line identity consists of a calling party BCD number and optionally, a calling party subaddress and/or a cause of no CLI.
The calling party BCD number information element is made up of a number of information units as indicated in 3GPP TS 24.008.
In addition to or instead of the calling party’s digits, the subscriber may be given the following information:
– screening indicator;
– presentation indicator.
Indicator values are given in 3GPP TS 24.008.
The calling party subaddress information element is made up of a number of information units as indicated in 3GPP TS 24.008.
The cause of no CLI information element is made up of a detailed cause of no CLI as indicated in TS 24.008.
A called mobile subscriber subscribing to calling line identification presentation service receives the call with the information indicated above, see figure 1.1.

SETUP
<————————————————————————————————————————
Calling party BCD number (screening indicator, presentation indicator, calling party digits),
Calling party subaddress, Cause of No CLI
NOTE: The calling party subaddress is passed to MSb if it is received from the originating network.
Figure 1.1: Notification by the network to the called mobile subscriber
When the calling line identity is not available, the presentation indicator which is given to the called mobile subscriber takes the value of "number not available".
Reference
3GPP TS 24.081 clause 1.1.
15.1.1.3 Test purpose
