MSCC (Vendor Variant 1)

MSCC Tab

 

 

           

MSCC (Vendor Variant None)

MSCC Tab

 

Credit Reported (Vendor Variant None)

  

Related Measurements

Measurements collected for Diameter Base related processing are reported on the Diameter DCCA Node report tab. Credit Control measurements are reported on the DCCA report tab.

 

DCCA Test

The DCCA Test is available only when Vendor Variant is None on the Test Configuration tab. Use the drop-down list to select whether the DCCA test is a One Time Event or Session Based.

Selecting the option as a One Time Event makes all the parameters on this tab unavailable.
CCR-T Delay on Terminated MSCCs (s)  

Use to configure a delay for the CCR-T Delay on Terminated MSCCs ensure that the Server has time to send RAR message.

NOTE:  Ensure that CCR-T Delay on Terminated MSSCs (Client side), is greater than the RAR Delay (on Server side) in OCS Node | OCS App.

Enter the number of seconds to wait before the session is terminated via CCR-T after receiving FUI (Final-Unit-Indication) AVP on all MSCCs.

A zero value indicates that session will be immediately terminated via CCR-T once all MSCCs are in terminate state.  

Tcl Parameter: DiaClnCcCcrtDelayOnMscc  

Options: 0 - 65535

Default: 0
Default CCF-Handling

Use the drop-down list to select the default failure handling mode for the Client node when Dedicated SUTs are defined.

Options: Terminate, Continue, or Retry-Terminate

Default: Continue

Tcl Parameter: DiaClnCcfHandling

 
Default Failover

When the SUT configuration includes a secondary server or proxy, you can use the drop-down list to enable or disable failover support.

Options: Supported or Not Supported

Default: Supported

Tcl Parameter: DiaClnCcFailover

Failure Handling

The server SUT may notify the Client node whether it supports failover with the CC-Session-Failover AVP, and it may instruct the node how to handle temporary or transport layer failures with the Credit-Control-Failure-Handling AVP. If the server does not include either or both AVPs in a CCA, the node's default behavior is governed with the following settings. If the server does include the AVPs, the values received will override the default behavior.
MSCC

The type of credit requested with the initial CCR and the actual credit usage that is reported by the Client with every update and termination CCR are defined in the Multiple Services Credit Control (MSCC) pane. The MSCC AVP is always included unless you check the Request Service Unit At Message Level box. A sub-tab is displayed for each MSCC, and the Client node will only report usage against a Rating Group if the DCCA SUT grants credit units for that group.
Number of MSCCs

Use the drop-down list to select the maximum number of MSCC AVPs.

NOTE: The Number of MSCCs can be > 1 only when you select Multiple Services Support.

Separate sub-tabs, labeled MSCC n, are displayed for each MSCC configuration.

Options: 1 — 10

Default: 1

Tcl Parameter: DiaClnNumMscc

 
Multiple Services Support

Use the Multiple Services Support checkbox to indicate Multiple Services Support during DCCA testing (RFC-4006).

NOTES:
  • Multiple Services Support is not available if Vendor Variant is not None (on the DCCA Server Nodal Test Configuration tab).
  • If Multiple Services Support is not selected and the Number of MSCCs is > 1, an error message displays and the Number of MSCCs is reset to 1.  

Tcl Parameter: DiaClnCcMssEn

Type: True, False

Default: True

NOTES: If Multiple Services Supported is not selected, (MULTIPLE_SERVICES_NOT_SUPPORTED), then the MSI (MULTIPLE SERVICES INDICATOR) is set to 0 (MULTIPLE_SERVICES_NOT_SUPPORTED) in the CCR. The DCCA Server Nodal emulation accepts the CCA response with the MSCC AVP that either does or does not have the Rating-Group AVP.

 
Include All MSCCs in Update Message

Use this checkbox to include all the Multiple-Service-Credit-Control (MSCC) AVP in the update message. (The MSCC AVP is in the Credit Control Answer (CCA) sent from the DCCA). This parameter is available only when Vendor Variant is None on the Test Configuration tab.

Tcl Parameter: DiaClnCcUpdateAllMsccsEn

 
Include Rating Group ID

The identifier of the Rating Group associated with a credit service.

Enter a valid Rating Group ID.

Range: N/A

Default: 1

Tcl Parameter:

DiaClnCcRatingGroupEn_1 DiaClnCcRatingGroup_1
DiaClnCcV1RatingGroupEn_1 DiaClnCcV1RatingGroup_1

 
AVP Configuration

Click the View/Edit button to view or modify the RADIUS VSA or Diameter AVP configuration for the test.

 
AVP Database Size (bytes)

AVP Database size for each Mscc configuration is set to zero by default. This buffer is used only when the auto increment is selected in the AVP Template and the AVP Database size should be large enough for holding the AVP Data. If the auto increment is not selected, the AVP Database size may be 0.

DB Size (bytes) has been added to the VSA/AVP configuration window. This is the value the AVP Database estimator calculates that is required for the AVP Database size. It should be used when determining the size of the AVP Database Size in Bytes.

Default: 0

Tcl Parameter: DiaClnMsccVsaDbSize_1

 
Max Num AVPs

Enter the maximum number of AVPs that can be included in a CCR message.

Tcl Parameter: DiaClnCcV1MsccVsaDbList_1

 
Apply Test Data File to AVP Configuration

See Applying TDFApplying TDF.

See Test Data Files for further explanation and sample files. If a sample is not found for the specific TDF, you can obtain a sample file from your Technical Support representative. You may also use the following options to select an existing TDF or create/edit TDF-CSV files (TDF-CSV Editor). 

For most TDF Parameters used for Applying Parameters, each row in the file is the overridden value for a different “Session”, aka a different UE. But some TDFs are done in other dimensions, like Bearers, eNodeBs, Subscribers (2 per UE sometimes) or even Hosts, etc. Tooltips on the TDF Parameter: 

Note that the “ID” is a unique ID. Please Provide the ID when reporting issues with a TDF. For TDFs that do not apply / override Parameters, but instead are just their own configuration or data or media files you won’t see TDF ID row details.

TIP: When including large files, please be aware of memory limitations, since the TDF Editor shares memory with the Client.

NOTE: The available TDF options vary. on the L3-7 | IPSec tab > IKE with RSA Settings you may only select the Certificate TDF from TAS (these are non-CSV TDFs).

In addition, where applicable, any rules for defining TDFs are included in specific Test Cases. (For example, In MME Node test case, see MME Node - Provisioning TDF.)

From the DMF Window, press Shift+Alt+A to display the  Save DMF as Tcl window. Click the Save to File button to save as Tcl file. See additional details on Using the Tcl API.

 

Select/Create a new TDF-CSV

Allows you to create a new TDF by entering a file name that doesn’t already exist or select an existing file by entering a file name that already exists.

Click to open the Select Existing or Create window.

  • Navigate to the relevant library/folder,

  • Enter the name of the file:

  • If the file name already exists, the file is selected and applied in the test case.

  • If the file name does not exist, a message displays that says you are creating a new TDF and the embedded TDF-CSV will be launched.

    • Click Yes to launch the TDF-CSV Editor and create/save the new TDF-CSV.

    • Click No to select a different file

NOTE: If you do not have permission to save in the selected library, an error displays when you try to create a new file.
TIP: You may also navigate to the relevant library/folder and select file, and click OK.

 

Upload a New TDF to TAS

Click to import a new TDF file from your local folder and select in the test Case (instead of having to go to TDF Admin).

  • Navigate to the file on your local folder and select.
  • Then navigate to the location (library) where you want to save it on the TAS. You may rename the file, if required.  

View Edit Selected TDF in TDF-CSV Editor

Available only when you have selected a TDF on TAS. Click to open the selected file in TDF-CSV Editor (in place, that is, within the Test Case).

Edit the file and save. You may also click Save As to save the edited TDF-CSV to a different library and also rename the file, if required.

NOTE: You may also select a TDF from a library to which you do not have write permissions, edit the file as required, and save (Save As) only to a different library with the same file name or a different name.

The only options available are Save As and Cancel.

Open Selected TDF in Standalone TDF-CSV Editor

Available only when you have selected a TDF on TAS. Select to retrieve the CSV file and open it in the stand alone TDF-CSV Editor.

Generate Stub TDF-CSV

TIP: Available only when a CSV specification has been defined for in the Test Case for the TDF widget ( View TDF Actions/Options Menu)

 

Opens an example context specific test data parametersexample context specific test data parameters, which you may save as a .CSV file or open in the TDF-CSV Editor.

 

Launch Standalone TDF-CSV Editor

Click to open a blank TDF-CSV Editor.

The Launch Standalone TDF-CSV editor options handles very large TDFs that may use too much Client memory if opened within the Test Case/in the embedded editor.  You may set the standalone TDF-CSV Editor memory high to edit large TDFs.
