Key Features

  • Unique and purpose-built test solution for testing fixed-mobile converging (FMC) networks and services such as LTE, IMS, VoLTE and VoIP
  • Large-scale emulation of subscribers, network elements and network clouds
  • Line-rate generation and analysis of 130 Gbit/s user-plane data
  • Hardware-based line-rate generation and analysis of user-plane data
  • Ability to generate and analyze tens of millions of any stateful user-plane sessions at line rate using the unique SmartReplay function, which is user-defined or imported from capture
  • Complete lifecycle testing: feature, load, interoperability and regression testing
  • Linear scaling—no performance degradation when expanding platform



Long-term evolution (LTE) and IP multimedia subsystem (IMS) technologies promise to deliver true fixed-mobile convergence by providing rich user experiences in both wireline and wireless networks.

Network service providers (NSPs) are struggling to cope with a massive amount of data on their 3G HSPA/HSPA+ networks and are now accelerating their LTE rollouts in order to deliver a truly mobile broadband experience to their subscribers.

IMS has been chosen has been chosen as the service delivery architecture to deliver rich user services over the LTE network, including voice (also known as voice-over-LTE or VoLTE), video and SMS services.

LTE and IMS are very complex to design and to deploy. In both networks, there are several network elements that need to interoperate with the existing networks (e.g., 2G/3G and VoIP) in order to provide a user experience that exceeds customer expectations.

Network equipment manufacturers (NEMs) and network service providers (NSPs) will need to perform extensive testing of both the IMS and LTE networks to reduce the risks that are typically associated with developing and deploying new and complex technologies.

Mobile Network Operators (MNOs) are constantly evolving their networks. And to meet rising competitive threats, they are aggressively planning to adopt software-based networks based on the principles outlined by Network Functions Virtualization (NFV). Successful deployment of NFV can only be done effectively through lab testing that incorporates both simulation and analyzing functions to achieve a faster mean time to identify failure.

Service providers are adopting web real-time communications (WebRTC) technology that provides many new monetizing opportunities to extend existing communication services (voice, video and data), and to create and augment wholly new and robust real-time services by leveraging existing investments on high-speed networks, such as long-term evolution (LTE) and IP multimedia subsystem (IMS).

Although WebRTC creates many great opportunities, service providers need to be careful what they wish for—customer expectations in today’s highly competitive environment leave little room for failure when it comes to the delivery of such innovative technologies and services. Operators can only accomplish their goals by offering uncompromising performance. This is best achieved by understanding the best practices for testing WebRTC networks, devices and services, as such knowledge will help ensure reliable network infrastructure in labs, in turn mitigating live network failures and avoiding customer dissatisfaction.
