2. CDMA-LTE Mobility Description

2.1. Overview

This chapter provides a high-level overview of the key software and hardware components necessary to configure and use the CDMA-LTE Mobility Test Packs.

2.2. Description

The CDMA-LTE Mobility Module is an integrated software component that allows you to perform interactive and automated testing of mobility scenarios on a UE device.

Support is provided for:

• CDMA 2000/EV-DO Bands: North American Cellular, North American PCS, JTACS, Korean PCS, NMT-450, IMT-2000, North American PCS 1.9GHz, and AWS.

• LTE Bands: 1, 2, 3, 4, 5, 7, 10, 12, 13, 14, 17, 20, 24, 25, and 26.

The CDMA-LTE Mobility 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 CDMA-LTE Mobility Test Packs

3.1. Overview

This chapter provides information on using CDMA-LTE Mobility 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

9. Setting up a New UE with the Data Client

3.2. Configuring the Platform Parameters

3.2.1. Supported Platforms

The CDMA-LTE Mobility 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 present in the system, as shown in Figure 3-1.

Chapter Three: Using the CDMA-LTE Mobility Module | 9

Set the SR8078 Enabled parameter to True to support the use of technologies in addition to LTE. Set the SR3452 Enabled parameter and SR3462 Enabled parameter to True to support CDMA/EV-DO. Set the E2010S Enabled parameter to True to support LTE. Set the SR5500 Enabled parameter to True to support SR5500 static mode.

Figure 3-1: 8100-B Series Platform Parameters

You must configure the LTE Mode parameter in the SR8078 Test Configuration Unit group and the Duplex Mode parameter in the SR3452 CDMA Network Emulator group according to the UE antenna configuration.

NOTE: The cable connections between the SR8078, SR3452 and SR3462 need to be consistent with the settings of LTE Mode and Duplex Mode parameters.


The following table shows the mapping between these parameters and UE antenna configuration.

LTE Mode Duplex Mode UE Antennas

Antenna Supported Technology

LTE-SVDO Config 1 False Ant 1 LTE TX/RX EVDO TX/RX

Ant 2 LTE Rx Div 1x TX/RX EVDO RX Div

LTE-SVDO Config 2 False Ant 1 LTE TX/RX EVDO TX/RX 1x TX/RX

Ant 2 LTE RX Div EVDO RX Div

LTE-SVDO Config 3 True Ant 1 LTE TX/RX EVDO RX Div

Ant 2 LTE RX Div 1x TX/RX EVDO TX/RX

LTE-SVDO Config 4 False Ant 1 LTE TX/RX EVDO TX/RX 1x RX

Ant 2 LTE RX Div 1X TX EVDO RX Div

LTE-SVDO Config 5 False Ant 1 LTE TX/RX

Ant 2 LTE RX Div

Ant 3 1x TX/RX EVDO TX/RX

NOTE: All platform parameters except LTE Mode and Duplex Mode, described above, are correctly configured when the system is delivered. It should not be necessary to modify them.


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, shown in Figure 3-2, 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. 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.

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 is used as a fallback if a command fails or is not provided.


3.3.2. UE Manual Interface Parameters

If the UE Control Method parameter under the UE Interface tab is set to “Manual”, if a command fails, or is not provided by the selected UE Control Method, the parameters of the UE Manual Interface are used. In this case, a window displays prompting you to perform the necessary action on the UE.

• Timeout Parameters: Specify how long the system waits before automatically selecting the defined Timeout Button. The timeout value is selected from a drop-down menu providing a range from "Disabled" to "Indefinite." A value of "Disabled" indicates no user prompt will display and testing proceeds 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; this 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.

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 CDMA-LTE Mobility 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.

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. CDMA-LTE Mobility makes use of the following commands:

Enable IMS Client

Disable IMS Client

Reset

Send SMS

Attach to Internet PDN

• Test AT Commands – Use this wizard to test AT commands to check if the UE responds correctly and reliably before testing.


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.

3.3.4. UE Capabilities Parameters

The UE Capabilities tab stores all general UE information and reflects the current settings of the UE. The CDMA-LTE Mobility module makes use of the common parameters shown in Figure 3-4. The security settings are shown in Figure 3-5 and Figure 3-6. The packet data settings are shown in Figure 3-7.

Figure 3-4: UE Parameters Window – Common Parameters

Figure 3-5: UE Parameters Window – LTE Security Parameters


Figure 3-6: UE Parameters Window — CDMA Security Parameters

Figure 3-7: UE Parameters Window — Packet Data Parameters


NOTE: Receiver Type specifies if the UE is a single receiver device of a dual receiver device. PDSN IP Mode and the PDN parameters in the UE file reflect the settings of the UE. The settings actually applied to the emulated network are specified by the test cases. If a test case does not specify these parameters, the settings in the UE file are used. The PDN x in test cases corresponds to the PDN x in UE file, where “x” is the number of PDN in the PDN array.

3.4. Configuring the Session Parameters

Session Parameters control the execution of the session as shown in Figure 3-8.

• Rerunning Test Cases: These parameters control the automatic rerunning of test cases that end with a final result of “Incomplete” or “Failed”.

• Rerunning Test Case Iterations: These parameters control the behavior of iteration-based test cases.

NOTE: Because CDMA-LTE Mobility 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 CDMA-LTE Mobility test cases automatically reset the UE at various points during the test; it is not necessary to set this parameter to “True”.

Figure 3-8: Session Parameters


3.5. Selecting the Parameter Files for Session Execution

2. Refer to Section 3.2.2 for more details on configuring the system for the specific UE you are testing.


3.10.5. Software and Services

Some of the tests supported by the CDMA-LTE Mobility test packs require the UE data connection to time-out and go dormant before continuing with the test. Modern devices tend to provide an “always connected” user experience. This is accomplished by various applications or services initiating data transactions in the background. This behavior can keep the UE from entering the dormant state and cause issues with testing.

In order to address this issue, these applications and services must be disabled after the specific UE is set up with the system. These applications and services are often UE-specific; so that no instructions can be given here for disabling them. Below is a list of services/settings/applications on the Client Laptop that may cause issues. In addition, advanced smart phone devices may have services running on the device itself that cause similar issues.

• IP services enabled in the Properties window of the network connection (only the QoS Packet Scheduler, Microsoft TCP/IP version 6, and Internet Protocol (TCP/IP) services are required).

• NetBIOS over TCP/IP

• teredo

• SSD

Parameter

Procedure Pathname Specifies the location of the test procedure file to be displayed in the Procedure result pane.

RAN Configurations File Path Specifies the location of the RAN configurations file. This file contains the configuration details of the RANs that are selected for performing mobility scenarios. This parameter is configured via a wizard. The wizard also provides access to edit the selected RAN Configuration file as discussed in Section 4.4.3.1 below.

Handover Type Specifies the Packet Call State required during the handover portion of the test. Valid Values: Idle/Dormant, Active.


Parameter

Handover During Partial Context Specifies whether or not the dormant handover to eHRPD is performed before the expiration of the UE Context Maintenance Timer.

Setup Voice Call on 1xRTT Registration Specifies whether or not a mobile terminated voice call is setup after UE registers on the 1xRTT network.

Mobility Phases Mobility Phase[x] Parameters for the different mobility phases. A mobility phase is a certain radio environment which is presented to the UE and the associated requirements for the UE behavior in that environment. For details on configuring Mobility Phases, refer to Section 4.4.3.2 below.

MPSR Timer Duration of MPSR Timer.

Phase Transition Behavior Specifies how to transfer between phases. "Enable/Disable RANs" enables RANs in next phase first, and then disables RANs in the previous phase. "Disable/Enable RANs" means RANs are disabled in the previous phase first, and then enables RANs in next phase.

Phase Transition Delay Specifies how much time to wait during phase transition.

Enable Strict Timeouts Enables or disables use of strict timeouts. If enabled, the test case will wait for the maximum timeout specified for each mobility phase even if all the requirements are met before the maximum timeout has expired (i.e. disabling this parameter may result in shorter test times).

RLP Logging Enabled Specifies if RLP Logging Enabled is triggered in C2K.
