15.3.1 CNAP/Normal Operation – Name indication contained in Setup message

15.3.1.1 Definition

To check that the UE presents the calling name identity correctly when name indication is sent in SETUP message to UE.

15.3.1.2 Conformance requirement

The calling name identity is made up of calling party’s name – up to 80 characters.

The UE shall be given one of the following in the name indicator:

– calling name identity;

– presentation indicator of presentation restricted;

– presentation indicator of name unavailable; or

– calling name identity and presentation restricted (for the case where the CNAP override category is provisioned).

If the network has received a non-zero SS screening indicator from the MS, then calling name information indicated above shall be sent to the MS as defined in figure 15.3.1-1. If the network did not receive a non-zero SS screening indicator form the MS, then calling name information shall not be sent to the MS.

Description of the user’s commands and of display of the answers from the network for interrogation of CNAP.

Initial conditions

System Simulator:

1 cell, default parameters.

User Equipment:

The UE is in CC state U10.

Test procedure

The UE is made to request interrogation of CNAP for all basic service groups.

Upon receipt of the interrogate operation in REGISTER message, the SS answers with a RELEASE COMPLETE message with the Facility information element containing a Return Error (return_error: SS not available) of the InterrogateSS operation.

The SS sends STATUS ENQUIRY, the UE responds with STATUS message indicating CC state U10.

Then again, the user requests interrogation of CNAP for all basic service groups.

Upon receipt of the REGISTER message, the SS answers with the RELEASE COMPLETE message (same PD and TI that in the REGISTER message) with the Facility information element containing a Reject (invoke_problem: resource limitation) of the InterrogateSS operation.

The SS sends STATUS ENQUIRY, the UE responds with STATUS message indicating CC state U10.
