The highly configurable end-points emulate real-world control and data plane traffic of millions of subscribers moving through the LTE, GSM, UMTS, eHRPD and Wi-Fi networks while consuming IMS and Over-The-Top services

Mobile Core

Mobile core networks are under constant pressure to support the demands of more subscribers and more data. Applications like VoLTE and Emergency Calling demand responsive, stable connections and high priority while the Internet of Things is driving a massive increase in the number of end-points that must be supported. Having a scalable, high-performance mobile core ensures responsive services and eliminates the chance of outages caused by the network.

Why Landslide Core?

Landslide Core is a scalable, high-performance platform designed to test and emulate 2G/3G/LTE mobile core networks. It generates the real-world control and data plane traffic of millions of mobile subscribers as they move through the network. Equipment manufacturers and operators worldwide use Landslide to redefine the boundaries of mobile network technology.

Landslide Core Key Features

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

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

Landslide Core Test Case
  • Landslide Core Test Cases
  • 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 Modeling
  • Mobility to/from LTE, GSM, UMTS, eHRPD and Wi-Fi networks
VoLTE/IMS node and SIP UE emulation
Voice over LTE (VoLTE) is the combination of IMS-based voice, messaging and video services over the 4G mobile network. To ensure a successful transition, mobile carriers and equipment manufacturers must ensure that voice quality and call reliability are as good as, if not better than, existing circuit switched voice services.

 
 
 


Landslide Wi-Fi

Mobile core networks are under constant pressure to support the demands of more subscribers and more data. Applications like VoLTE and Emergency Calling demand responsive, stable connections and high priority while the Internet of Things is driving a massive increase in the number of end-points that must be supported. Having a scalable, high-performance mobile core ensures responsive services and eliminates the chance of outages caused by the network.

Wi-Fi Offload

With the ability to test from the core network to the Wi-Fi offload gateways now extended to the access points, Spirent Landslide ensures that mobile operators can deliver reliable and seamless services to subscribers under fully loaded conditions. Mobile operators and equipment vendors can validate subscriber experience as they move between nationwide mobile networks, carrier Wi-Fi hot-spots and private wireless networks.

Landslide Virtual

With the emergence and growing success of new services such as voice over LTE (VoLTE) and the Internet of Things (IoT), Mobile Carriers are evaluating the current state and capacity of their deployed infrastructure. The most commonly adopted, cost effective solution to grow capacity and performance is virtualization. Early adopters are already deploying virtual networks for the following functions:
  • 3GPP and 3GPP2 2G/3G/4G Mobile Packet Cores
  • VoLTE/VoIP
  • IMS systems
  • Diameter clients and servers
  • Wi-Fi APs and offload gateways
  • Integrated Firewalls, DPI engines and security gateways

Virtualizing the EPC brings with it a complex set of technical challenges that mobile carriers will need to overcome. This paper describes those challenges, and sets out a 4-step validation methodology to guarantee a successful vEPC deployment, as well as optimal management of the live network.
