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.

3.3. 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

• 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
parameter to True.

UE Control Method

are:

Reset for Ensure Idle

10 | 8100: Data Retry-LTE User Manual

NOTE

Figure 3-2: UE Parameters Window – UE Interface Parameters

: 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 drop­down 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
timeout expires.

OK or Cancel button is selected when the

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

Timeout Button for

the

Answer Voice Call

Answer Voice Call

. This allows the UE time to auto-answer the call, and

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.
