Defines attributes used in PDP context requests sent from the MNs to the SGSN.
Starting NSAPI |
The starting Network Service Access Point Identifier. A combination of this value and the IMSI uniquely identifies a PDP context. This value increments for each primary and secondary PDP context associated with a given mobile subscriber. Range: 5 — 15 (0 — 4 are reserved for GGSN error handling) Default: 5 Tcl Parameter: SmNsapi |
|
PDP Type |
Select the Packet Data Protocol type that is requested by the MNs. Options: IPv4 or IPv6 Default: IPv4 Tcl Parameter: PdpType |
|
Signalling Connection |
Use the drop-down list to define whether the Iu signalling connection is maintained after PDP context activation. If Keep Active is not selected, the RNC will send a Release Request at the time specified. The MN will initiate the Service Request procedure to re-establish the connection when necessary.
Options: Keep Active, Tear Down Upon Context Active, or Tear Down After Delay Default: Keep Active Tcl Parameter: SmKeepSigActive If you select Tear Down After Delay, you can enter the number of seconds to wait, after context activation, before sending the release in the Delay field. Tcl Parameter: SmSigConnTearDnDly Related Measurements |

Teardown Indicator | Available on MME Nodal (Iu-PS) and UMTS test cases. Per TS 24.008 section 9.5.14.1. Select to Tear Down indicator in "GSM A-I/F DTPA - Deactivate PDP Context request". This IE is included in the message in order to indicate whether only the PDP context associated with this specific TI or all active PDP contexts sharing the same PDP address and APN as the PDP context associated with this specific TI shall be deactivated. Tcl Parameter: SmTeardownIndEn | |
PDP Context Update
|
Use to configure the SGSN Node to send periodic Update PDP Context messages. Enter the Update Interval in seconds. Range from 0 to 10000. Default = 5. Tcl Parameter: PdpContextUpdate Tcl Parameter: PdpContextUpdateInterval | |
Available in MME Node when Mobility = Inter-Tech or Command Mode and Interface = Target Iu-Ps or Target Gb. Select to configure the "Activate PDP Response" with one of the possible options: Options: Respond with Requested Type (default), Respond with IPv4 Address Only, Respond with IPv4 Address Only. Tcl Parameter: SmPdpResponseType |
||
|
In SGSN Node test case, select Deactivate PDP and enter the Deactivate Interval to periodically send a Deactivate PDP Context (with cause code: reactivation required) after the PDP context is Activated. You may configure to Deactivate once or select Continuous Deactivate PDP. Tcl Parameter: DeactivatePdpEn Tcl Parameter: DeactivatePdpInterval Tcl Parameter: DeactivatePdpContinousEn |
Access Point Name |
Use the APN sub-tab to define the APN values assigned to PDP contexts. You can define one APN for all contexts, a different APN for every context, or a set of APNs that are distributed among all contexts. With the retry capability, you can also configure alternate APNs that will be used if a context cannot be established using the preferred APN. You can manually define different APN values, generate incrementing values during test execution, or use a combination of both methods. You can choose to use the same APN configuration for all contexts (Summary) or define an APN configuration by primary context (Individual). Select Individual and the number of tab depends on the number of Default Bearer per Session you selected on the Test Configuration Tab | Mobile Subscriber pane. For example, if you selected 4 Default Bearer per Session, APN P0, P1, P2, and P3 sub-tabs displays for each primary context assignments. |
Starting Auto-Incrementable APN |
The format used to generate incrementing APN values. See the Auto-Increment section in Parameter Types and Features for more information incrementing formats and methods. Range: N/A Default: ssenoauth146 Tcl Parameter: SmApn_0
|
Manually Specify First |
Use the drop-down list to select the number of APN values that you will manually define. The appropriate number of value fields (APN 0 — APN 9) are enabled based your selection. The values that you define in these fields will always be used first when you select Round Robin mode. Tcl Parameter: SmApnNumSpecifiedApns_0
|
Total APNs |
The maximum number of APN values that will be generated for the contexts, including both incrementing values and manually-defined values. Range: Variable (limited by the maximum number of PDP contexts) Default: 1 Tcl Parameter: SmApnTotalApns_0
|
Round Robin |
Use the checkbox to enable round-robin APN assignment. When you define multiple APN values, the first value in the list is assigned to the first context, the second value is assigned to the second context, and so on. Manually-defined values are always selected first and when that list is exhausted, incrementing values are used. After the test has cycled through the total number of APNs, the next context is assigned the first APN value in the list. A context will use the same APN through the life of the test as long as the context can be successfully established using that APN. In a Session Loading test, for example, a new APN is not obtained every time the context is re-established. Tcl Parameter: SmApnRoundRobin_0
|
Retries |
The number of times the PDP context will attempt to be activated if the first attempt did not succeed. When you enable Retries, each retry attempt will use the next APN value in the list if you have defined multiple APN values. Range: Variable (limited by the maximum number of PDP contexts) Default: 0 (retries are disabled) Tcl Parameter: SmApnRetries_0 Related Measurements |
The Quality of Service pane allows you to specify the QoS parameters for a primary PDP context. The GGSN/SGSN needs the QoS information for IP packet Uplink and Downlink. The GGSN/SGSG SUT ensures that the granted QoS does not exceed the Authorized QoS per IP flow. The authorized bit rate/sec is defined separately for Uplink and Downlink packet flow.
You can define one QOS for all Primary PDP contexts or a different QOS for each Primary PDP context.
When you select Individual, a Primary Context eg; P0) sub-tab is displayed for each Primary Context per subscriber (selected on the Mobile Subscriber pane on the Test Configuration tab). the number of tab depends on the number of Default Bearer per Session you selected on the Test Configuration Tab | Mobile Subscriber pane. For example, if Default Bearer per Session is 3, the Primary Context QoS tabs displayed are Default, P0, P1, and P2. |
||
In UMTS and GPRS testing, select the R97 Only checkbox to send only 4-byte R97 QoS attributes (2G specification).
|
The Modified Quality of Service pane allows you to specify the QoS parameters for secondary PDP context. In MME Nodal test case, the Mobile Quality of Service pane is available on the Target Iu-PS | SM tab and Target Gb | SM tab when Handoff Protocol is UMTS (IuPS over IP) or GPRS respectively, and Test Activity is Sequencer or Command Mode (MME Nodal Test Configuration).

Selecting Additional Parameters allows you to further select P-CSCF IP Address request, DNS address request, DHCP address allocation request, IM CN flag request, MSISDN request, etc as part of PCO IE.
Type: True/False
Default: False
Tcl Parameter: PcoAddEn
Tcl Parameter: NasAddEn
Tcl Parameter: Gtp2PcoAddEn
NOTE: The P-CSCF is the entry point to the IMS domain and serves as the outbound proxy server for the UE. The UE attaches to the P-CSCF prior to performing IMS registrations and initiating SIP sessions. The P-CSCF may be in the home domain of the IMS operator, or it may be in the visiting domain, where the UE is currently roaming. For attachment to a given P-CSCF, the UE performs the P-CSCF discovery procedures. Attachment to the P-CSCF is necessary for the UE for initiating IMS registrations and sessions. In these procedures, the UE first establishes the IP connectivity access network (IP-CAN) bearer. Then, the UE sends a query to the DHCP server for retrieving the IP addresses and FQDN (Fully Qualified Domain Name) of the P-CSCF. After the DHCP query, the UE performs a DNS query on the FQDN received from the DHCP server. In response to the DNS query, the IP address of the P-CSCF is returned (referred as the DHCP-DNS procedure for P-CSCF discovery). If the FQDN of the P-CSCF is pre-configured in the UE, the UE can directly query the DNS server and get the IP address of the P-CSCF. |

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.)
