2. Data Retry - LTE Description
2.1. Overview
This chapter provides a high-level overview of the key software and hardware
components necessary to configure and use the Data Retry - LTE Test Packs.
2.2. Description
The Data Retry - LTE Module is an integrated software component that allows you to
perform interactive and automated testing of Data Retry scenarios on a UE device.
Support is provided for:
•LTE Bands: 1, 2, 4, 5, 7, 10, 12, 13, 14, 17, 20, 24, 25, and 26.
The Data Retry - LTE module test cases run with the Test Manager software. This provides
an easy way to automate test sessions with analysis and reporting capabilities.

3. Using the Data Retry - LTE Test Packs
3.1. Overview
This chapter gives information on using Data Retry - LTE from Test Manager .
This includes the following steps:
1. Configuring the Platform Parameters
2. Configuring the UE Parameters
3. Configuring the Session Parameters
4. Selecting the Parameter Files for Session Execution
5. Locating the Test Cases
6. Creating a Custom Test Suite
7. Configuring Test Case parameters
8. Running a Test Suite
3.2. Configuring the Platform Parameters
3.2.1. Supported Platforms
The Data Retry - LTE Test Packs support the following platforms:
•8100-B Series
3.2.2. 8100-B Series Platform Parameters
The parameters for the 8100-B Series platform configure the technologies that are
present in the system, as shown in Figure 3-1. Set the
E2010S Enabled parameter to
True to support LTE. The SR8078 Enabled parameter can be set as either True or False;
depending if TCU is integrated in the Data Retry - LTE system.
NOTE
: The platform parameters are correctly configured when the system is delivered.
It should not be necessary to modify
them.

Chapter Three: Using the Data Retry-LTE Test Packs | 9
Figure 3-1: 8100-B Series Platform Parameters
3.3. Configuring the UE Parameters
The level of automation and reliability of the system is heavily dependent on the ability
of the system to control the UE. UE parameters are configured to facilitate these
activities.
3.3.1. UE Interface Parameters
The UE interface parameters specify how the UE is controlled during test case execution.
The options for the
UE Control Method are:
•Manual: The system prompts the operator to perform actions on the UE.
•AT: The system issues the specified AT commands to control the UE.
•Custom: (Advanced) Allows custom UE control. If Custom is selected, the UE Control
Sequence File parameter specifies the Control Sequence file used by the system.
The ability of the system to return the UE to a known state before execution of a test case
is important. If the UE supports a reliable reset command, set the
Reset for Ensure Idle
parameter to True.

10 | 8100: Data Retry-LTE User Manual
Figure 3-2: UE Parameters Window – UE Interface Parameters
NOTE
: In cases where the UE Control Method is set to anything other than
“Manual”, the Manual method will be attempted as a fall-back if a command fails or
is not provided.
3.3.2. UE Manual Interface Parameters
If the UE Control Method parameter of the UE Interface tab is set to “Manual”, if a
command fails, or is not provided by the selected UE Control Method, the UE Manual
Interface parameters are used. In this case, a window displays prompting you to perform
the necessary action on the UE.
•Timeout Parameters: Specifies how long the system waits before automatically
selecting the defined Timeout Button. The timeout value is selected from a drop-
down box providing a range from "Disabled" to "Indefinite."
A value of "Disabled" indicates no user prompt will be displayed and testing will
proceed as if the UE control was completed successfully. A value of “Indefinite”
indicates the function will wait indefinitely.
Note that even if Manual control is not selected, it may be used in case of failure. If
the timeout value is set to “Indefinite”, the system will wait indefinitely, which may
not be desirable.
•Timeout Button Parameters: If a timeout other than "Disabled" or "Indefinite" is
specified, these parameters specify if the OK or Cancel button is selected when the
timeout expires.

Chapter Three: Using the Data Retry-LTE Test Packs | 11
Figure 3-3: UE Parameters Window – UE Manual Interface Parameters
Configuring these parameters correctly can be effective in allowing some level of
automation; even if AT commands are not available or supported for the UE under Test.
For example, if the UE can be configured to auto-answer an incoming call, you can set
the timeout for
Answer Voice Call . This allows the UE time to auto-answer the call, and
the Timeout Button for
Answer Voice Call can be set to OK. This configuration allows the
device to reliably answer network-initiated voice calls.
3.3.3. UE AT Interface Parameters
If the UE reliably supports AT commands, AT control can be very useful. The UE is
connected to the Data Client PC for AT control after the manufacturer's driver software is
installed.
The following parameters are provided:
•Client IP Address: Set this parameter to the IP address of the Data Client PC. NOTE:
The default address 192.168.0.61 should not be changed.
•Primary COM Port Settings/Secondary COM Port Settings: These parameters
configure the standard serial port parameters. Two COM ports can be used for
different commands. NOTE: The Data Retry - LTE Module only makes use of the
Primary COM Port.
Port: Set this parameter to the port on the Data Client PC assigned to the modem
when the UE is connected.
Bits per Second: Configure the baud rate.
Data Bits: Configure the number of data bits.
Parity: Configure the parity.

12 | 8100: Data Retry-LTE User Manual
Stop Bits: Configure the stop bits.
Flow Control: Configure the flow control.
Enable DTR: Enables Data Terminal Ready Signaling.
Enable RTS: Enables Request To Send Signaling.
New Line: Specifies the new line terminator to use.
•Commands: Configure the available AT command strings.
•Test AT Commands: Use this wizard to test AT commands to check if the UE
responds correctly and reliably before testing.

Chapter Three: Using the Data Retry-LTE Test Packs | 13
3.3.4. UE Capability Parameters
UE Capability parameters configure the security and authentication settings for the UE as
shown in Figure 3-5. These parameters also include configuring the PDN number and
properties, as shown in Figure 3-6.
The following parameters are provided for security and authentication settings:
•AS Security: AS Security settings
•NAS Security: NAS Security settings
•NAS Authentication: NAS Authentication settings
•HSS Settings: HSS Settings
Figure 3-5: UE Parameters Window –Security and Authentication Parameters
The following parameters are provided for configuring PDN number and PDN properties:
•PDNs: Parameters for supported PDNs.
•PDN [N]: Specifies valid PDN settings.
•IP Address Type: Specifies the type of IP address the UE will request. Valid Values:
IPv4, IPv6, IPv4v6.
•APN: Specifies the Access Point Name (APN) the UE will communicate with.
•Services: Parameters for mapping services to PDNs.
•Service [N]: Parameters for mapping the service to the PDN.
•Service: Specifies the service. Valid Values: Administrative, Application, IMS, and
Internet.
•PDN: Specifies the PDN that carries this service.

Figure 3-6: UE Parameters Window – UE Capability Parameters for PDN
NOTE
: There is great variability in the AT commands supported by UE vendors and
how reliably they work. Experimentation may be necessary to determine the best
settings.
3.4. Configuring the Session Parameters
Session Parameters control the execution of the session, as shown in Figure 3-7.
•Re-running Test Cases: These parameters control the automatic re-running of test
cases that end with a final result of “Incomplete” or “Failed”.
•Re-running Test Case Iterations: These parameters control the behavior of iteration-
based test cases.
NOTE
: Because Data Retry – LTE test cases are not iteration-based; these parameters
are not used.
•Reset UE between Test Cases: Resetting the UE between test cases can improve
system performance and stability in some cases.
NOTE
: The Data Retry – LTE test cases automatically reset the UE at various points
during the test
; it is not necessary to set this parameter to “True”.
