Description

Spirent’s Landslide™ LTE Test Application enables mobile service providers and the equipment vendors to test the performance of their LTE networks and devices. The system emulates mobile users and applications at scale ensuring networks are capable of keeping up with the massive amount of control traffic generated by millions of smartphones and deliver the bandwidth and quality of service necessary to deliver a broadband experience over the mobile network.

Landslide LTE Test Applications provide a comprehensive end-to-end test system that emulates millions of mobile data subscribers, all simultaneously accessing the LTE-enhanced packet core network or handing over between the LTE network and GSM, UTMS, or eHRPD networks. By emulating the key LTE packet data network elements and combining control plane and data plane simulation, the Landslide LTE Test Applications provide real-world emulation of millions of UEs in various stages of activation, deactivation and handovers between cells. Emulation takes place while sending and receiving real-world application data.

Applications

• Validate system scalability and identify capacity limits
• Measure control plane capacity
• Stress data plane performance
• Perform Intra-LTE and I-RAT mobility testing
• Characterize system before trial/delivery
• Identify performance ceilings
• Busy hour Call Attempt Testing

Features & Benefits

• TCL Interface allows the user to control/monitor the Landslide from a higher-level management system, thus making it possible to compile specific test reports for both the emulation (Landslide) and the device under test
• Realistic, real-world simulations that allow equipment vendors to accurately specify the performance characteristics of their equipment under real-world conditions
• Simultaneous control and user plane that allow service providers to measure the performance of their network and to validate new features and services in the lab
• Unmatched scalability allows the user to simulate subscriber loads ranging from a small rural town to the largest metropolitan city
• Standard Web browser interface means no need to load software onto user equipment
• Emulation of multiple network elements allows the user to test in a variety of network topologies which provides more effective utilization of lab equipment and reduces capital expenditure and ongoing support costs associated with a test lab
• Automation control allows the user to run many test cases simultaneously or serially on multiple Landslide test servers, creating real-world scenarios for heavy load and long duration stability tests
• MME Nodal Testing allows the user to isolate the MME in a “nodal” configuration to specifically test the performance and scalability of the MME itself
• Intra-LTE Mobility—Landslide provides the ability to test virtually all Inter-LTE mobility scenarios
• Inter-Technology/I-RAT Mobility—Landslide provides the ability to test virtual all handover scenarios between LTE and GSM, UMTS, and eHRPD networks. Landslide can emulate or allow a real SGSN or HSGW for this testing
• SGW Nodal—The user can isolate the SGW in a “nodal” configuration to specifically test the performance and scalability of the SGW itself
• PDN GW Nodal—The user can isolate the PDN GW in a “nodal” configuration to specifically test the performance and scalability of the PDN GW itself
• End-to-end testing allows the user to test the entire LTE core
• With Landslide’s LTE Gateway Functional Test Option the user has the capability to edit message headers and add/modify/delete message IEs for GTPv2 messages. Both methods can be used to generate error conditions
• Landslide also offers a PCRF Node Emulator that can be used in cases where a real PCRF is not available. The PCRF emulator supports the Gx and Gxx interfaces for LTE
