7 2. LTE-NAS Functionality Testing 2.1. Description This test pack is designed to provide test scenarios for testing LTE NAS functionalities. NAS aka Non Access Stratum is a present in the Layer 3 LTE Protocol Stack. It is responsible for mobility management, session management, and connection management. NAS test packs provide a flexible testing environment that is easy to customize and includes a variety of scenarios for optimal UE testing. The test pack includes both success and negative scenarios. Test cases range from UE attach to IPv4/IPv6/IPv4v6 type PDN, multiple PDN scenarios, service request scenarios, and Attach Reject scenarios. The CS8 Mobile Device Test System supports multiple band and bandwidth ranges. Support is provided for: LTE Bands: 1, 2, 3, 4, 5, 7, 10, 12, 13, 14, 17, 20, 24, 25 and 26. LTE Bandwidth: 1.4, 3, 5, 10, 15 and 20. NOTE: 1.4M, 3M, 15M, and 20MHz bandwidths and Band Classes 1, 2, 3, 5, 12, 20, 24, 25, and 26 have not been fully validated Supported Platforms The Reference Test Packs support the following platforms: LTE-Only Platform: E2010S SR3620 Landslide PDSN Emulator (R610) SR3920 V2 Application Server (R610) Client Laptop Cisco 1921 Router Dell 6248 Switch LTE-UMTS-FADE Platform: E2010S SR5500 SR3620 Landslide PDSN Emulator (R610)

Customizing Test Cases This section provides detailed instructions to customize test cases from the test pack to your requirements for testing. To customize a particular test case: 1. Select the test case from Test Manager. Under the Test Case Parameters pane, expand the Initial Conditions step, as shown in Figure 2-1. Figure 2-1: Test Manager Selecting a Test Case 1. Click Subtype. The Spirent Interactive Editor window displays, as shown in Figure 2-2.

Update the corresponding parameters and click OK to save your changes Additional Information The following tips can assist you in configuring a NAS-related test case. 1. Updating multiple configurations at the same time is only possible in the Initial Conditions Step 1. All other steps only allow you to update parameters associated with a single item. 2. Testing NAS-specific test cases requires you to modify the LTE and Core Network parts. 3. You can change or modify band or EARFCN parameters by navigating to SS>LTE>eNodeB[]>eNodeB>PHY, as shown in Figure 2-3. After making changes, click OK.

Although Test Manager allows you to add AT commands directly into the test case, defining AT command in UE file is a best practice for managing AT commands throughout the suite. 5. You can type in the AT commands for the UE in the UE file, name it, and save the changes for future use, as shown in Figure 2-4. For more information, refer to the Test Manager Reference Manual.

11 Chapter Two: LTE-NAS Functionality Testing 9 Figure 2-4: Entering AT Commands 6. To use AT commands in your test case: a. In the Test Case Step select Type as "Action" and Subtype as "ExecuteATCommand". b. Click the button. A new Spirent Interactive Editor window displays, as shown in Figure 2-5. c. Enter the command name within square brackets and click OK.
